1. Multimedia Software
Multimedia software is components in data processing system, in the form of
programs to control working it multimedia computer system. This software
classified to become three parts that is multimedia programming language, system software
multimedia and software the application of multimedia.
Multimedia Programming Language
Multimedia Programming Language is languages applied by programmer for
makes the application of multimedia. Its(the example Assembly, C, C++, Power Builder, Delphi, SQL, Visual of Basic,
and Java.
System Software ( System Software)
This software consisted of Operating system ( Operating System) for example DOS ( Disc Operating
System), Windows 95/98/ME, Windows NT/2000, Windows XP, Windows Vista, UNIX, LINUX or Mac
OS. Other software is the application of utility ( utility application) for example the application of Antivirus.
Software The Application Of Multimedia
Software the application of multimedia is applications made by by personal or
organization for user operating in specific multimedia areas like graphic 2D,
modelling and animation.
Text Processor Peripheral
The application of text processor which many applied for example Microsoft Word, Word Star for Windows,
Word Perfect and Star Writer, while some the application of text processors having the character of open source
for example Open Writer, KWRITER and Abi Word.
Animation Processor Software and Graphic 2D
The application of graphic processor 2D is divided to to become two parts that is:
a. Graphic 2D Vector, for example Corel Draw, Macromedia Freehand and Adobe Illustrator.
b. Graphic 2D Image ( Raster), for example Adobe Photoshop, Jasc Paint Shop Pro, Gimp.
c. Animation, for example Macromedia Flash.
Animation Processor Software and Graphic Modelling 3D
Example of from software Animasi and modelling Grafik 3D is 3D Studio MAX, MAYA,
Softimage, LightWave, Blender and others.
Software Authoring Multimedia
Authoring is the application of computer giving opportunity to user for
develops a software with dragging and dropping various multimedia objects
without having to knows usage and programming language understanding, for example Macromedia
Authoring, while the application of authoring equiped with by programming for example Macromedia
Director by equiped [by] Lingo ( Programming language).
This peripheral type divided to become three categories that is authoring bases on page, authoring bases on
icon and authoring based on time.
Authoring bases on page is authoring is working bases on page or book with
organization of elements in the page or book. Example of from the application of this is
HyperCard and ToolBook Assistant.
Authoring bases on icon to apply concept flowchart to make elements stream
multimedia connected together or x'selfly peculiarly presents
activity flow diagram along the length of ramification line, its(the example is Microsoft Power Point and
Macromedia Authorware.
2
Authoring based on time was expansion of multimedia package as organization
object along the length of time line. Frame which is organizational in massage then is presented again
to user. Example of application using this way is Macromedia Director.
Authoring DVD is application applied to present menu interaktif movie, its(the example
it is Pinnacle Impression, Sonic ReelDVD and Ulead DVD Workshop.
Application Software Bases On Web
Example of design products web for example is Macromedia Flash applied for
makes graphical animation at web, Macromedia Dreamweaver and Microsoft Front Page.
The Application Of Multimedia for excellence competes in company
The application of company multimedia in various areas for example human resource,
produksi/operasi, accountancy and finance, information systems and marketing.
Application at Exploitation Area of Human resource
Multimedia is interesting and good training media recognized as term Computer
Based Training ( CBT). For example business IntallShield makes multimedia software which
majors for training. The application of other for example rekrutmen employee, like the one is done [by]
by L'OREAL.

Information network backbone and communications in Indonesia
Information network backbone and communications in Indonesia practically requires infrastructure backbone which is reliable, cheap and can be built according to requirement of support from ICT would for prosperity ( e-prosperity). E-inclusion involving outlying public to access Internet must be supported by election of correct technology. Wi-Fi is one of its(the choice. At this handing out will be studied about Wi-Fi, its(the comparison is with a few other information access technology, problem faced is including network security and interference, things which can be done to increase utility Wi-Fi, audit to exploiting of Wi-Fi which there have, and possibility that its(the development is in Indonesia especially as supporting facilities for infrastuktur information, communications and education in Indonesia.
1. WIRELESS FIDELITY ( Wi-Fi)
Wireless LAN gives level of flexibility and portability that is much higher is compared to ordinary LAN. WLAN mengkoneksikan other computer and component having wireless adapter into network through Access Point ( AP). Configuration WLAN in general is differentiated to become 2 kinds, that is infrastructure and ad hoc. At infrastructure type, AP incircuit direct to cable network. While at quad type hoc, AP incircuit to other AP passed mechanism of quad hoc. AP usually has coverage area to 100 metre, usual called as cell or range.
Wireless Fidelity ( Wi-Fi) be name given by Wi-Fi Alliance description of product wireless local area network to ( WLAN) which based on standard Institute of Electrical and Electronics Engineers ( IEEE) 80211. Kinds of variants 80211 has been released by visible IEEE at Tabel 1. Type that is most popular is applied in Indonesia and world is standard 80211b ( indoor) and 80211g ( outdoor). Both having compatibility from the angle of equipments user, so that user 80211b earns easily move to network 80211g when beyond room.
2. COMPARISON WITH OTHER TECHNOLOGY
Technology wireless long distance, hardly potency to be applied at area pedesaan/pedalaman. Main characteristic from this type technology is expense of its(the low development, amenity pambangunan, and its(the ability to reach wide geographical region. As access technology expected in the future, Wi-Fi must can give excellence signifikan compared to technology which there have now.
21. Comparison with WiMAX
Compared To Wi-Fi, WiMAX-yang has been diujicobakan in FTUI Februari 2006-adalah a real expensive technology in development initially. From the angle of its(the equipment industry, WiMAX also have been far lag compared to Wi-Fi. WiMAX designed to have standard which more pre-eminent and more completely is compared to Wi-Fi[2]. But, whereas WiMAX still in standardization level, equipments Wi-Fi has disseminated wide among world public, so that the price also downwards drastically. Now have been many companies, trying to university and hacker digs ability of deeper Wi-Fi again. And is not impossible thing if ability and popularity Wi-Fi would continuously increase during which will come. WiMAX possibly will very compatible applied for rural areas which its(the polpulation is low and distance between its(the populations is also far, while Wi-Fi would continuously grow and applicable to various network types like LAN, Neighbourhood Area Network ( NAN) and MAN [ 2].
22. Comparison with 3G
Compared to 3G, giving more Wi-Fi is opportunity compared to 3G because its(the cheap cost. 3G from initially just had required a real big cost for frequency spectrum license problem, while Wi-Fi using not to release cost at all for the thing. Peripheral 3G at side user which is the existing has started circulates also the price expensive, while communication means having adapter WiFi built indium have been many circulating and the price also increasingly downwards. From the angle of speed of its(the access, 3G promises will give speed of data until 2 Mbps, practically have never reached the speed one hundred %, because having to shares with other user [ 3]. usual maximum Throughput is given is around 100 Kbps.
3. FITUR SECURITY AND SAFETY Wi-fi
Main problem of which must be paid attention when choosing a form of information network is its(the security and safety facet. Mainstay a network hardly determined by fitur adequate security and safety. Standard Wi-Fi x'self has owned fitur elementary security and safety that is Service Set ID ( SSID) and Wired Equivalent Protocol ( WEP) [ 1].
31. Fitur elementary security and safety
3.1.1. Service Id Set ( SSID)
SSID is a string applied to define common roaming domain between a group of AP. SSID which is different at a group of AP enables overlapping in network wireless. SSID also can be conceived of password base. where an user will not can access network without his(its. Weakness from this fitur is that AP sends in broadcast its(the SSID the several per second so that equipment of analyst 80211 applicable to read it. That someone cannot step into network incidentally mere, hence SSID must be changed from its(the default value [ 1].
3.1.2. Wired Equivalent Protocol ( WEP)
To lessen security and safety problem, 80211b defines method autentikasi and encryption named by WEP. Encryption WEP based on algorithm RC4, what applies lock 40 bits and initializing vector ( IV) 24 random bits [ 1].

Programming with Java
Java as one of programming language has just promised many amenities for junior programmer and also senior. this Tutorial will bring you to recognize farther this language through solution of simple scheme model concept and guide its use.
Is Java?
Java was programming language orients object developed by Sun Microsystems since the year 1991. This language developed with model is looking like language C++ and Smalltalk, but is designed that easier to be used and platform independent, that is can be implemented in various operating system types and computer architecture. This language also designed for programming in Internet causing is designed that be safe and portabel.
Platform Independent
Platform independent means program written in language Java to earn easily is removed between various operating system types and various computer architecture types. This aspect of vital importance to be able to reach purpose of Java as programming language Internet where a program will be implemented by various computer types with various operating system types. This character valids for level source code and binary code from program Java. Differs from language C and C++, all data types in language Java has consistent measure in all platform types. Source code program Java x'self not necessarily be altered at all if you compile wish tore- in other platform. Result from compile source code Java is not machine code or instruction of specific processor to certain machine, but in the form of bytecode which in the form of extension file . class. Bytecode earns your direct execution in every platform that by using Java Virtual Machine ( JVM) as interpreter to bytecode.
JVM x'self is an application run is above an operating system and translates bytecode program Java and executes it, so that in concept can be considered to be an interpreter. execution process of describable Java program as in Gambar 1. In this way, a program Java which has been compilation will be able to run in what particular platform, so long as there are JVM over there.
Kompiler and interpreter for program Java is in the form of Java Development Kit ( JDK) what produced by Sun Microsystems. this JDK can be download is free from situs java.sun.com. Interpreter for program Java x'self often also is called as Java Runtime or Java Virtual Machine. Interpreter Java, without its(the kompiler, called as Java Runtime Environment ( JRE) can be download also in the same situs. To develop program Java is required [by] JDK, while if only wish to implement bytecode enough Java with JRE only. But to execute applet ( a bytecode Java also) you usually no more require download JRE because browser which Java-enabled has owned JVM x'self.
Library
Besides kompiler and interpreter, language Java x'self has library which is big enough of which can water down you are in making an application swiftly. this Library has included for graphic, design user interface, kriptografi, network, voice, database, and others.
OO
Java is programming language orients object. Object-oriented programming clearly is technique to organize program and can be done with most all programming languages. But Java x'self implementation has various facilities that a programmer can optimal of object-oriented programming technique.
A few additional comparisons with language C and C++, Java many inheriting orientation concept of object from C++ but by eliminating complication aspects in language C++ without lessening its(the strength. This thing waters down newbie programmer to study Java but lessens facility of experienced programmer in mengutak-atic a program. At the opposite of amenity that is on the market Java, facility broadness library Java x'self makes a programmer to require time which is not shortened to be able to master usage of library-library.
Starts Java Programming
To make program Java, like has been mentioned before all, you requires JDK. installation process of JDK hardly easy and doesn't require certain knowledge. But to apply it your need to do some adjustment with your operating system. Generally you that need to do is enter path to directory JDK Anda to setting path at your operating system. Takes example directory JDK Anda is C:\jdk14 hence at Windows 98 you enough adding comand line SET PATH=C:\jdk14\bin at your autoexecbat file. For Windows NT/2000/XP Anda enough adding directory C:\jdk14\bin at variable path in System Environment. Its way: icon right click My Computer, select;chooses Properties. Then select;chooses tab Advanced. Then clicked button Environment Variables, variable searching path, then adds path directory JDK Anda into the variable. For Linux, adds comand line SET CLASSPATH=(direktori your jdk) to your profile file. To try JDK, types java comand and javac at shell prompt ( or DOS Command Prompt). If the comand have been recognized hence java program or javac will present sintaks usage. For amenity and various your addition facilities can apply Integrated Development Environment ( IDEA) for language Java like Visual Café from Symantec or JBuilder from Borland.
Stages;steps sequence which you must do to make a program Java simple is:
1. Makes source code program with any text editor. Remembers, the file extension must . java and case sensitive.
2. Compile source code by order of javac. For example: javac HelloWorldjava. If success, result of his(its is file bytecode ends . class.
3. Executes bytecode by order of java. Parameter from this comand is file name result of compilation without extension . class. Example: java HelloWorld.
Source Code
Following code for HelloWorldjava:
public class HelloWorld
{
public static void main(String[] args)
{
System.out.println("Apa World News?");
}
}
And this an other example, that is simple applet to present text in applet. Calls this file so called HelloWorldAppletjava:
import java.awt.Graphics;
public class HelloWorldApplet extends java.applet.Applet
{
public void paint(Graphics g)
{
gdrawString("Apa Kabar Dunia?", 5, 25);
}
}
Clearly can be paid attention that second structure of program hardly looking like, and only differs in in execution context. Both this programs will be studied furthermore after we to study way of compile and executes the program.
Important to remember that language Java haves the character of case sensitive, so that you must pay attention to usage of uppercase and small. Besides writing of source code program is not must pay attention to certain form, so that you might possibly write down all lines source code in a line of you doesn't forget membubuhkan semicolon sign (;), or writes down every word in a line separate. But is suggested you to follow layout like at example of that your easy to read program and understood.
Compilation
After both files disave by the name of HelloWorldjava and HelloWorldAppletjava, we compile will second of the program by order:
prompt> javac HelloWorldjava
prompt> javac HelloWorldAppletjava
Need to be paid attention that active directory of you are the existing is directory place of you puts down the program files. You still your program compile can from directory differs from comand:
prompt> javac ( directory program)/namafilejava
After this comand completed, you will see that has been created two file . class, that is bytecode result of compilation source our code.
Sintaks Program
Now we will try studies elements in both source code.
In The Early Of Listing 2 we find import comand. At this early stage you should have knowledge that the statement only functioning waters down writing of method or in other programming language called as procedure or function. So You only need to write Graphics in the place of java.awt.Graphics, because we have imported java.awt.Graphics.
Then in each listing the

Builds The Application Of Web with AJAX
Most all sure people have ever applied gmail, yahoo mail, google sugest or Google maps, and sure of all people realizes that the application is application bases on web which is dynamic and applies new programming concept. If it is observed farther the application seen like the application of desktop without using any plug-in and also special facility from web browser.
What is it is returned that semua?konsep does about gerangan? Devils having devils simply concept used in the application of web is AJAX. Food is the AJAX? AJAX itself is elongation from Asynchronous Java and XML. Term AJAX applied at website having interaction with server through javascript in asinkron ( background), so that consumer is me-load not necessarily overall of contents of page. This thing causes time irritant and bandwidth, also yields website which more and more interaktif.
Usually at application bases on traditional web, to change content a page hence page di-load mustre-, however by using javascript or cascading style sheets ( CSS), programmer web can make an dynamic application without having to re- me-load keseluruhn contents of its(the page. In this article writer will try explains in detail how technics makes application to base on web using concept AJAX.
Definition AJAX
AJAX itself introduced by an expert of program maker especially programming bases on web. The a real meritorious man not other and not not be Rasmus Lerdorf, from this Rasmus Lerdorf green thumb also some times last borned PHP.
To the application of AJAX in website, what required is browser providing service Javascript, and component XMLHTTP for consumer Internet Explorer ( IE), and XMLHttpRequest for Firefox, Safary, other Opera and browser. The conditions is almost certain has fufilled, remembers internet consumer a lot to apply IE and Firefox.
Actually there is no new thing in AJAX, because applied is technology javascript, which notabene have been long enough been applied. Therefore, for which have been accustomed to javascript, would easily study AJAX. This solution doesn't emphasize at one of technology ( Javascript, AJAX, HTML, PHP), however entirety from the thing. This thing is because usage of AJAX is not only at side client ( browser), but also entangles response from server.
By using this concept, page HTML can make koneksi in asinkron to server by the way of taking XML or document text. Hereinafter XML or document of this text will be applied by javascript meng-update to or modifies Document Object Model ( DOM) at page HTML.
Henceforth this technology also is recognized web remoting or remote scripting. Developer Web can combine indium plug, java applets or hidden frame mengemulasikan interaction to between page HTML with document XML. In technology Javascript has been provided an object that is XMLHTTPRequest. This object have been many disupport by many browsers like Internet Explorer, Firefox, Opera, Netscape and others.
Following illustration depicting interaction AJAX with Server :
Concepted this AJAX idea initially told by Rasmus Lerdorf. Rasmus Lerdorft arises this AJAX concept in a miling list ( milist). Having beginning of from milist is concept AJAX then is recognized and developed by many people. Following contents of milist sent by Rasmus Lerdorf.

I find an lot of this AJAX stuff an beet of a hype. Lots of people has
been using similar things long before it became " AJAX". And it really
isn't ace complicated ace an lot of people make it out to is. Here is a
simple example from one of my apps. First the Javascript:
function createRequestObject() {
var ro;
browser var = navigatorappName;
if(browser == " Microsoft Internet Explorer"){
ro = new ActiveXObject("MicrosoftXMLHTTP");
} else{
ro = new XMLHttpRequest();
}
return ro;
}
var http = createRequestObject();
function sndReq(action) {
httpopen('get', ' rpc.php?action='+action
httponreadystatechange = handleResponse;
httpsend(null);
}
function handleResponse() {
if(httpreadyState == 4){
var response = httpresponseText;
update var = new Array();
if(responseindexOf('|' != - 1)) {
update = responsesplit('|');
document.getElementById(update[0]).innerHTML = update[1];
}
}
}
This creates a request object along with an as of neodymium request and handle
response function. So to actually use it, you could include this js indium
your page. Then to make one of these backend requests you would tie it
to something. Like an onclick event or a straight href like this:
< a href="javascript:sndReq('foo')">
That means that when someone clicks on that link what actually happens
is that a backend request to rpc.php?action=foo will is sent.
Indium rpcphp you might has something like this:
switch($_REQUEST['action']) {
case ' foo':
/ does something /
echo " foo|foo done";
break;
...
}
Now, look at handleResponse. It parses the " foo|foo done" string and
splits it on the '|' and uses whatever is before the '|' ace the dom
element indium id your page and the part after ace the new innerHTML of that
element. That means if you has a div tag like this indium your page:
< div id="foo">
< /div>
Once you click on that link, that will dynamically is changed to:
< div id="foo">
What is it is returned that semua?konsep does about gerangan? Devils having devils simply concept used in the application of web is AJAX. Food is the AJAX? AJAX itself is elongation from Asynchronous Java and XML.

Definition AJAX
AJAX itself introduced by an expert of program maker especially programming bases on web. The a real meritorious man not other and not not be Rasmus Lerdorf, from this Rasmus Lerdorf green thumb also some times last borned PHP.
To the application of AJAX in website, what required is browser providing service Javascript, and component XMLHTTP for consumer Internet Explorer ( IE), and XMLHttpRequest for Firefox, Safary, other Opera and browser. The conditions is almost certain has fufilled, remembers internet consumer a lot to apply IE and Firefox.
Actually there is no new thing in AJAX, because applied is technology javascript, which notabene have been long enough been applied. Therefore, for which have been accustomed to javascript, would easily study AJAX. This solution doesn't emphasize at one of technology ( Javascript, AJAX, HTML, PHP), however entirety from the thing. This thing is because usage of AJAX is not only at side client ( browser), but also entangles response from server.
By using this concept, page HTML can make koneksi in asinkron to server by the way of taking XML or document text. Hereinafter XML or document of this text will be applied by javascript meng-update to or modifies Document Object Model ( DOM) at page HTML.
Henceforth this technology also is recognized web remoting or remote scripting. Developer Web can combine indium plug, java applets or hidden frame mengemulasikan interaction to between page HTML with document XML. In technology Javascript has been provided an object that is XMLHTTPRequest. This object have been many disupport by many browsers like Internet Explorer, Firefox, Opera, Netscape and others.
Following illustration depicting interaction AJAX with Server :
Concepted this AJAX idea initially told by Rasmus Lerdorf. Rasmus Lerdorft arises this AJAX concept in a miling list ( milist). Having beginning of from milist is concept AJAX then is recognized and developed by many people. Following contents of milist sent by Rasmus Lerdorf.

I find an lot of this AJAX stuff an beet of a hype. Lots of people has
been using similar things long before it became " AJAX". And it really
isn't ace complicated ace an lot of people make it out to is. Here is a
simple example from one of my apps. First the Javascript:
function createRequestObject() {
var ro;
browser var = navigatorappName;
if(browser == " Microsoft Internet Explorer"){
ro = new ActiveXObject("MicrosoftXMLHTTP");
} else{
ro = new XMLHttpRequest();
}
return ro;
}
var http = createRequestObject();
function sndReq(action) {
httpopen('get', ' rpc.php?action='+action
httponreadystatechange = handleResponse;
httpsend(null);
}
function handleResponse() {
if(httpreadyState == 4){
var response = httpresponseText;
update var = new Array();
if(responseindexOf('|' != - 1)) {
update = responsesplit('|');
document.getElementById(update[0]).innerHTML = update[1];
}
}
}
This creates a request object along with an as of neodymium request and handle
response function. So to actually use it, you could include this js indium
your page. Then to make one of these backend requests you would tie it
to something. Like an onclick event or a straight href like this:
< a href="javascript:sndReq('foo')">
That means that when someone clicks on that link what actually happens
is that a backend request to rpc.php?action=foo will is sent.
Indium rpcphp you might has something like this:
switch($_REQUEST['action']) {
case ' foo':
/ does something /
echo " foo|foo done";
break;
...
}
Now, look at handleResponse. It parses the " foo|foo done" string and
splits it on the '|' and uses whatever is before the '|' ace the dom
element indium id your page and the part after ace the new innerHTML of that
element. That means if you has a div tag like this indium your page:
< div id="foo">
< /div>
Once you click on that link, that will dynamically is changed to:
< div id="foo">
CHICKEN CONDUCTING PETELUR
1. BRIEF HISTORY
Chicken petelur is female chickens of adult looked after is special to be taken its(the egg. Poultry chicken provenance is coming from partridge and mallard catched and looked after and can lay eggs quite a lot. Year after year partridge from world region is selected tightly by the expert. direction of Selection addressed to production which many, because the partridges can be taken its(the egg and flesh hence direction from production which many in the selections started specific. Chicken selected for purpose of produce of flesh is recognized as chicken broiler, while to producing egg is recognized as chicken petelur. Besides, selection also is aimed at finite eggshell colour then is recognized white petelur chicken and chicken petelur cacao. the Cross and selection is done sufficiently long so yielding chicken petelur like the one is present. In each time cross, bad thrown and goodness defended (" always is purified"). This then is recognized as pre-eminent petelur chicken.
Steps on beginning of year 1900-an, the permanent wild chicken at its(the place is chummy with life pattern of public is rural. Enters period 1940-an, people starts recognizes chicken besides the wild chicken. From here, people starts differentiates between Dutchman chickens ( Nation of that moment Dutch colonizes Indonesia) with wild chicken in Indonesia. This wild chicken then is named local chicken which then is called as kampong chicken because existence of the chicken of course in rural. Whereas Dutchman chicken called as with overseas chicken which then more chummyly with the title country chicken ( the scorpion still be pure blooded country chicken). A kind of this chicken able to be met in year 1950-an looked after by some people chicken devotee. Till end of period 1980-an, Indonesian people is not many recognizing classification of chicken. At the time, chicken character is assumed [by] like kampong chicken only, if(when its(the egg is delicious is eaten [by] hence its(the flesh is also delicious is eaten. But, the opinion simply not true, chicken negeri/ayam this race simply lays eggs many but not delicious of its(the flesh.
Chicken which first entrance and starts bred at this period is race chicken petelur white leghorn which is thin and generally after pot is clean a period of his(its productive. Antipathy people to race chicken flesh sufficiently long finite
nearing period end 1990-an. At the time starts merebak poultry broiler which of course special for flesh, whereas chicken petelur dwiguna/ayam brown petelur started mushroom also. Here public starts consciousness that race chicken has classification as reliable petelur and pedaging which delicious. Takes its rise also keen emulation between eggs and race chicken flesh with egg and kampong chicken flesh. Meanwhile brown race chicken's egg started to wind, while kampong chicken's egg starts depressed at usage of traditional food recipe only. Emulation this is indicating the hoisterous of poultry petelur.
Kampong chicken of course lays eggs and its(the flesh is of course lays eggs and its(the flesh is edible, but cannot be classified as double use chicken in komersial-unggul. Its(the cause, base genetis between kampong chickens and this double use petelur race chicken of course differs in far. Kampong chicken ably remarkable adaptation of the good. So kampong chicken can anticipate change of climate carefully is compared to race chicken. Only ability of its(the genetis differentiating second production of this chicken. Although the race chicken also comes from wild chicken in Asia and African.
2. SENTRA BREEDING
Chicken has been developed very fast in setiapa state. Sentra poultry petelur have been met in all pelosok Indonesia especially at Pulau Jawa and Sumatra, but poultry has disseminated in Asia and African and some of Europes.
3. J E Nitrogen I Sulfur
Chicken type petelur is divided to to become two types:
1) Light Petelur Chicken Type.
This chicken type called as with white petelur chicken. This light petelur chicken has body which ramping/kurus-mungil/kecil and eye shines. Its(the fur having colour clean white and red berjengger. This chicken comes from pure blooded of white leghorn. This strain chicken difficult to be searched, but commercial light petelur chicken many sold in Indonesia with various names. Every pembibit chicken petelur in Indonesia surely had and sells light petelur chicken ( white petelur) this commercial. This chicken can lay eggs more than 260 eggs per year produce of hen house. As petelur, chicken type this of course special to lay eggs is just so that all x'self abilities aimed at ability to lay eggs, because its(the only a few flesh. This sensitive light petelur chicken of hot weather bound and hubbub, and this chicken easy to surprise and if surprising this chicken its(the production would quickly downwards, so do if(when heat.
2) Chicken Type Petelur Medium.
This chicken body wight enough weights. Though that, wt. still residing in between light petelur chicken weights and chicken broiler. Therefore this chicken called as chicken type petelur medium. This chicken body not thin, but nor seen fat. Its(the egg is quite a lot as well as can yield flesh which many. This chicken called as also with double use type chicken. Because its(the brown colour, hence this chicken called as with chicken petelur cacao that is generally has brown fur colour also. Marketing people to tell preferred cacao egg than egg whites, if it is seen from its(the skin colour is of course more draws brown than white, but from the angle of gizi and same relative taste. One different things is the price is marketing, the price of costlier cacao egg than egg whites. This thing is because of heavier cacao egg than its(the egg whites and production slimmer cacao egg than egg whites. Besides flesh from chicken petelur medium would more saleably sold as broiler with delicious taste.
4. BENEFIT
The pre-eminent petelur chickens is very good used as germplasm to yield certifiable seed. Result of dirt and waste from cutting of chicken petelur is changeable by-product become manure, compost or energy source ( biogas). While like intestine and chicken viscera can be made as poultry foodder after dried. Besides chicken is exploited also in religious ceremony.

EXPLOITING of COMPUTER IN PUBLIC
11 ANTECEDENTS
Without we realize, computer has stood in public. This thing applies in developed countries and also in state is being growing in Indonesia. Computer actually doesn't differ from other tekhnologi product like train, plane, television car and others. What differentiating computer with other product be the ability to be able to be program to execute assorted of duty with high speed and correctness.
The physics experts, electronics and computer has developed microprocessor which big is capable. Such processor many applied as part of controller of other energy product like guided missile, motor vehicle, aeroplane, camera, personal computer and this thing always grows as according to development of epoch.
Computer at the moment many applied as a means of assists to process various data types like processing of student value with computer, making of value list, calculation average of class nor reports for kepentinag evaluation of education. Computer also have been many applied to print electrical invoice receipt, telephone, credit card and others.
Basically computer is applied as a means of assists menyimpan to, process and takes again data or information required. Work area that is also starts affecting as seen exemplified following :
" Preparation of correspondences up to storage of archive is office.
" Filming in the field of animation and effects 3 dimension
" Seeking of book based on book heading and author's name in library
" Administrative services and quality of medical service at hospital.
" Ordering of ticket peswat flies at perusahan international and also domestic air transport.
" administration of State like data administration of officer, data administration kependudukan, making of KTP, SIM and others.
" Usage of computer in the field of industry.
Some examples is upper is a few example of exploitings of computer in various work areas. Still many other areas which has not been mentioned. Appreciation to impact of a new product not always must have of circumstantial knowledge about the product. Observation to impact of computer is public able to be done by exploiting tekhnologi is around [by] public.
12 Some The Application Of Important
Computer is a real basic and important invention. Computer is not only assists works however changing mode of action and at the same time generates new challenge and problems in area.
1.2.1 Clever Cars
Microprocessor dimanfaatkat has to increase comfort and safety pilots car. For example in the year 1985, oldsmobile from US has applied control system to base on microprocessor at its(the product. Microprocessor gets data input from some sources, like :
" Metre injection pump ( machine burden)
" Alternator ( rotation mesin/menit)
" Machine cooling system
" Absolute pressure sensor to watch circulation and pembuanagan gas
" Transmission tooth
The input data diolah by microprocessor to perform [a] precaution that machine is not too temperature, watchs rotation of machine, machine burden and usage of correct transmission tooth and as according to requirement.
1.2.2 Electronic libraries
Space and time was two main problemses faced by Perpustakaan these days. Cost needed to by menyimpan book, magazine, journal, newspaper and handing out always swells. Beside the matter, library officer burden to serve reader to find reading material required increasingly day increasingly heavy because reading amounts that is increasingly increases. This thing results slow of service.
The problems is tried overcome with help of computer. Computer at this sat have been can replace powered katalogdan accomodated big. Data base system jugatelah grows so that able to manage data in jumlha which very big. Progress in tekhnik re- seeking is information had enabled done seeking to return inside information of a flash in the pan.
Development of tekhnik printing with help of computer membuaka new nuance in moth-balls information. Book or magazine printed always diolah and crosschecked with computer, so that information of obtainable elektronis directly.
1.2.3 Operations of Air Traffic
Air traffic was traffic that is very gristle in human life, although in indonesia number of its(the air transports still be relative low compared to advance nations. Even though operation of air traffic have been executed modernly, done with sophisticated equipments bases on computer. This thing is done by defaults in operation of air traffic will cause on fatal.
1.2.4 Weather Data Processings
Weather data collected from hundreds or even thousands of station of station of watcher in bumidan is space. This data channelled through international telecommunications channel to center weather data processing. To form model peraamalan of local weather.
1.2.5 Video Games
This game very quickly gets marketing and particularly in liking by the rising generation. Various game types which have never is realized to become reality. Place of game spread over dimana-mana in center expenditures, recreation or in nearly school. So young children started forgets its(the obligation as pupil or as member of public. The this game supporters express that game character is educate and increases coordination between eyes and hand. There is whereas pendapay telling that youngster taking a fancy to permaianan of video they will interest with computer and programmer however more personal computer in reality applied for game from at programmer.
Recognition of Internet
11 Internet Understanding
Internet is gathering of related personal computer one otherly in the form of network. Network is created [by] through telecommunications channel, like telephone. Personal computer can reside in various places that is separate, either in international and also national region.
Every personal computer merged into by network can communicate in the form of transfer of lateral data of image and voice. In a second and in two directions. Other term for internet is virtual world, cyberspace,homepage ata www ( world wide web)
Internet is property of world public. Nobody or institute which can claim Internet as property of his own. As member of internet, you can do transfer of text and various messages with having million man in business, academy, other goverment and organization, access software, documents about art, politics, culture, picture, map, weather, library catalogue and various information from various place of whole world.
Internet supposed as an fairish electronic town of giant, where every resident has address which applicable to send letter. If we like to circled enough town with its(the computer as vehicle.
Operation of convergent network to supporting facilities for telekominikasi. Its(the low-speed line using modem and telephone channel; while its(the throughway using ISDN or frame relay.
12 Development of Internet
Internet has created new world for human life. Which its(the apparition is started started [by] when department of defence of United States makes project of ARPA ( Advanced Research Project Agency) with the title ARPAnet. ARPANET semuala designed to find reliable computer network, and smpai how big movable information and all standards determined to become genesis for expansion of new protocol recognized as TCP\IP.
Then NSF ( National Science Foundation) continuing this project and then creates network x'self so called NSFnet based on technology IP used by ARPAnet with telephone channel as supporting facilities for transmission. Because its(the cost is too height, hence the side of NSF decides makes alternative where computer will relate to local network, then this local network distributes to other computer network.
This success alternative, so that its(the computer network is developed furthermore by Merit Network Inc to cooperate with IBM and MCI, however relationship still limited to academy area, governmental research institute and institution in United States.
13 Internet Facility
Internet as global computer network has proven can water down its(the user to communicate and memeperoleh information. Following is enclosed facilitys owned by internet, inter alia :
" E-mail
" Mailing List ( newsgroup)
" File server/transfer
" Web/Distributed Multimedia database, as plane
" Video and Suara
Electronic mail ( E-mail), By using this facility you can send letter and file between computers keseluruh world only pay [for] modulation of local telephone and news which you sends to until purpose in a few minute.
Newsgroup ( mailinglist), This facility built with the same tekhnik with electronic spreading process. With this facility news in distributing kebanyak user at the same time, so that its(the user can do discussion, seminar, delivered a lecture, had conference in electronic without engagement by time and space.
File server/transfer. This facility enables you copies file which you to require the in its(the internet and menyimpan at your computer file.
Web/Distributed Multimedia Database, facility facilitating you in doing navigation of information in internet.
Video Facility and Suara, with this facility you can find voice and picture which in big supply in internet.
14 Type Koneksi Internet
In doing tacking or conection with internet there are some ways adapted for level of access from internet communications. There is three type koneksi from internet that is :
" Online or dial, account through internet provider this account often is called as also as shell account. this more limited Pengguanaan majored at low cost. Online accounts provided from some facilities that is internet provider, online service commercially and university, goverment or organization non profit.
" Koneksi SLIP/PPP, With this koneksi hence transfer of quicker data so that you can implement the program is internet, you no more require sends data per character through modem
" Facility which can be rented or leased line. To use line rented need to use TCP/IP software at one particular LAN. To make a facility which can be rented very complex and required [by] time. Usually company using this line used to be sold again small and middle keperusahan.

way of having business with forex
Forex is not business making we are rich direct during quickly, we must many learnings ( if we have ever fallen in this business). Altogether need to process, uses virtual funds/demo former account. Didn't assume this business negativity if we loss have ever and didn't make easy this business if we profit have ever. Forex is pure of business, pure worked. We need to work not merely using physical but fikiran & our emotion also must be drawn up ( forgiveness is not pretend learns). Rata2 man who failed in this business is because terlau palters this too business idealist then of opinion quickly produces fruit result in a crack, in the end swimmingly directlies enter market that is in the end loses.
This of I sharing strategy would safe of forex my other trading of which you able to try. You please try in Virtual/demo former account to prove it.

How uranus helped neptunus
Yes, uranus helped astronomers discover the planet neptune! Just like trains, planeta also follow a time table as they move across the sky. Astronomers worled out a timetable that uranus was supposed to follow but it was unpredictable-sometimes it was late for a ‘station’ in the sky. It was as if uranus was hitting a bump on its path around the sun. Astronomers suggested that this bump could be another planet pulling at uranus with its force of gravity. Because they knew the ‘bus stop’ at which uranus was late, they could work out where the other planet should be.
Uranus
Uranus, the seventh planet from the sun, was the first planet to be discovered with a telescope. It consists of a rocky core, surrounded by a deep ocean and covered by thick clouds of gas. This planet is about 3000 million kilometres from the sun. Ayear on uranus is equal to eighty-four earth years and a day is about sixten to eighteen earth hours long.
The many-ringed planet
The most intriguing thing about saturn is the many rings around it. I bet you do not know that the rings are actually billons of piece if ice. Each piece of ice (from tiny specks to large clumps of snow) revolves around saturn just as the moon circles earth. Saturn is actually a huge ball of gas that gets thicker towards the centre. Although saturn is huge – it is also the second largest planet after jupiter- it is not as heavy as as ball of water of the same size. In fact, if there were an ocean big enough to contain it. Saturn would actually float int the water.
The giant planet
Jupiter is by far the biggest planet in the solar system. It is more then eleven times bigger than earth. Another special thing about jupter is that it is made of liquis. Mercury, venus, mars and earth are solid balls of rock but jupiter, the fifth planet from the sun, is a big ball of liquid with an iron core. Do you know that there has been a huge hurricane whirling in jupiter’s atmosphere for hundreds of years? Can you imagine living in a planet like that?
Life on mars
With all the similarities between earth and mars, many people thuoght that there could be life on mars. In 1877, schiaparelli, an italian astronomer, thought that he saw straight lines on the planet. Another american astronomer, percival lowell, thought that these lines were canals and concluded that they muast have been bilt by the people of mars. He said that the people of mars planted crops along the canals. Then a few years ago, some space craft, without people on board, visited mars. They had special automatie spades at tached to them. The spades dug up some soil in mars and brouht it back to earth. Test were carried out but they revealed no evidence of any life form on mars. Photographs proved there were no canals
The red planet
Mars is sometomes called the red planet because it shines with a reddish gleam. Fierce windstorms whip sand up from the plains of mars and fill the air with dust. This dust gives sky of mars its strange crimson colour. Like earth, mars has volcanoes, canyons and mountains but they are many bigger than those on earth. In fact, mars is more like our earth than any of other planets. It is not as close to the sun as mercury and venus, so it is not as hot as they are. Mars even has seasons like those on earth but they last twice as long.
Our earth
The planet earth is in the most favourable position in the solar system. Being the third planet away from the sun, it is neither too hot nor too cold. This is also one of the reasons why it is able to support animal life. The earth is not a round ball as everyone thinks it is. It is actually a sphere with a slightly flattened top and bottom, where the north pole and south pole are, respectively. You may find it hard to believe but the earth spins on its axis. What is an axis? It is an imaginary line that connects the north and south poles. And this is how you get night and day.
Earth’s twin
Venus is often called earth’s twin because it is nearly the same size as earth. But it is really nothing like our world! Firstly, the thick clouds are made of droplets of sulphuric acid – a chemical so strong it can dissolve metal. The winds in venus blow harder than the strongest hurricane on earth. The sky is constantly li by lightning, wich flashes as often as twenty times a minute. The atmosphere is hotter than that in mercury because it traps heat from the sun – like a greenhouse.
oil slicks
oil pollution is a major problem in the seas. when oil is spilt in the seas, it will float and form a slick. oil, as you know, does not dissolve and it is difficult to remove it. this will have a teerible effect on the environment. a spill can kill at least 30.000 seabords. that is how much damage an oil slick can do. imagine the hundreds of oil slick that occur due to human carelesssnes. effect of pollution in the water can endanger the lives of the animals liveing there

water pollution
we all know that water is very importan for our survival. we can't live without it. yet for something so importan, we treat it very badly.
there are many ways in wich we pollute the water. we use water tu flush away human waste products. we use rivers to carry away our waste. we dump refuse into the lakes and oceans. many industries dump unwanted chemicals into rivers and seas. this is because it cheaper to dispose of it this way. we have been dring this for thousands of years and you can imagine how polluted our rivers are now

Closest to the sun
Mercury is the closest to the sun. It is also the smallest planet, being two-fifth the size of earth. Like our moon, mercury is a bare, rocky planet covered with thousands of millions of craters. If you were on mercury, the sun will appear many times larger and brighter than it looks from earth. This is because mercury is only abotu 58 million kilomtres away from it. You will fry if you were on the side of mercury facing the sun because it is very hot
Do you know a year in mercury is a long s eighty-eight earth days? But a day in mercury is nearly as long as a year!

The sun’s family
Our earth is part of a family that belongs to the sung. The other members of this family are the eight planets. If you look at the solar system, you will notice that the sun is the other planets revolve around the sun in a path called an orbit.moons, on the other hand, revolve around their respective planets
Save our sun
Scream! Shout! Make as much noise as you can! The dragon is eating the sun!
What? Yes, that was what the ancinet chinese believed when there was and eclipse of the sun. An eclipse of the sun happens when the moon passes betwen the earth and the sun. This means that the sun will be totally blocked so there is darknes on that part of earth. The chinese believed that if everyone made a lot of noise, the dragon would be frightened into leaving the sun alone.
The people who lived long ago knew very litle about science and mathematics. They only knew about things that happened in the part of the world that they lived. So when they looked up at the sky and saw the sun slowly disappearing, they thought that the dragon was swallowing the sun.

When the planets were born
How old is the earth?no one really knos but astromomers think that the solar system began about 45000 million years ago. In the vast darknes of space, a gigantic cloud of gas and dust once spun around like a huge flat wheel, millions of kilometres across the universe. Most of the gas in the cloud, or nebula, was hydrogen.
After millions of years, the space of the nebula was changed by gravity. This is a force which pulls things towards each other. The gravity of the spinning nebula pulled gas and dust into the centre, creating a tightly packed lump. This huge lump was shaped like a ball and waas the beginning of the stars we call the sun
As the new star grew larger and more larger and more tightly packed, the gas at its centre became very hot, aking the sun shine brightly. Far away from the shining sun, the force of gravity began to pull gas and dust into much smaller centres, like whirlpools in space. Over millions of years, these whirlpools also became tightly packed balls of gas and dust. Today, we know them as the nine planets of our solar system.

In the beginning
Along, long time ago, in a galaxy far, far away, there was abig bang! Matter (dust and gas cloud) was sent flying out in all directions. But what caused the huge cosmic explosion? Astronomers(scientist who study the stars and galaxies) believe that all the matter in the universe was squeezed very tightly into firebll. The temperature of this fireball was so high that it exploded. And that is why this huge explosion is known as the big bang!
Can you guess what happened to the matter that was sent flying after cosmic explosion? It cooled and became stars and galaxies. One of these galaxies became a group of planets known as the solr system
