CHAP III RESEARCH
METHODOLOGY 3.1. Method of Data Collection
1. Studies Library At this stage of data collection by the
literature study, the authors find references relevant to the object to be written.
Reference searches carried out in libraries, bookstores and online through the internet.

In addition to the literature study authors also collect references and
material from the thesis or research paper in which one object of the discussion is
almost the same as those written by authors, for example, is a thesis about the
E-Commerce
3. Observation Authors performed data collection in
the field to obtain information about system requirements. Observations carried
out by coming directly to the agency concerned ie BPPT Agency for the
Assessment and Application of Technology, to see how directly the
actual object of research. This is done to obtain clear information about the data and
information required in the design application.
4. Kueisioner Kueisioner aims to find out how many
products are in demand in the market with consumers from various circles, especially
students. The questionnaire in the form of questions which will be incorporated into
the return channel TV poll
3.2. Systems Development Methods
In the method of system development, the author uses one model SDLC System
Development Life Cycle is the waterfall. Metod waterfall is often called linear sequential model
sequential liniear provides the approach flow in the software life sekensial or sequentially starting
from the analysis, design, coding, testing, and stage support support.

Stages of the Waterfall method
1. Analysis of application requirements
Collection process needs to be done intensively mespesifikasikan application
needs to be dipaham. Moreover the analysis performed to understand the
applications that will run in order to define the problems so that applications can
determine the application requirements outlined in preparation to the design phase.
2. Design
At the design stage is given a clear overview to the user and the complete
design of the application to be made to the parties involved in developing a
application. This phase starts from the beginning of the design process, tools or
equipment with the help of Data Flow Diagrams DFD as a tool and as a process
flowchart
3. Coding and Implementation
The design must be translated into a software program. The results of this stage
is a computer program in accordance with the design have been made at the design
stage.
4. Testing
Phase of testing was conducted to obtain and ensure that the software produced is
valid and in accordance with the needs that have been described. This is done to
minimize the error error and make sure the output output generated in
accordance with the design.
5. Support or Maintanance
There’s possiblelity that the application would change when it was run. Change
can occur because of errors that arise and are not detected during testing.
Maintenance phase can repeat the process of development without having to create
new applications. Besides the maintenance phase or maintenance is also performed as
a maintenance activities are also updating
the information contained in the application in accordance with the
conditions that currently occur.
CHAP VI RESULTS
In general, digital TV broadcasting is not too different from the analog TV broadcasting. Only, in
the broadcasting digital TV signals sent by pemancara not broadcast but was in the form of
digital data that has been processed previously. This is possible because in some of the analog TV
stations already use digital devices in the production process in the studio source release.
Initially the results are still shaped analog broadcasts will be digital undergo a process of
change by using a DAC Digital-to-Analog- Converter to be broadcast. With conditions like
this, analog TV stations are already doing in the studio digitization process will be easier to
immigrate.
Picture 4.1. Illustrations in the DAC One of the advantages of digital TV
broadcasting is there an application that can run between the digital data broadcast called MHP
middleware. With the middleware will enable an application running on a digital TV broadcasting so
that digital TV can be interactive TVs that connect producers and consumers indirectly.
To design the application in general easy to understand and to devise solutions to problems that
have been found. The design of the transition diagram using two different diagrams of Data Flow
Diagrams DFD as tools and as process flowchart
Stages of Development of the Waterfall
1. Analysis
At this stage of analysis the authors find the data and information according to the
needs of the application is also designing the concept of the application and look for
software that is compatible with making the application.
To create an T-Commerce application with Return Channel workmanship performed
by the same two stages of file creation. NKR for T-Commerce and Return Channel and
making a server for the Return Channel Designing applications for digital TV
using the two software is iCareus and NetBeans.
On the concept of the menu on the application used the concept of a scene that is
the turn of the menu display content according to the selected menu. In addition to the
concept of a scene menu there is also the concept of a sub-menu menu, only if using
this concept will make the application look untidy.
2. Design
Once the needs analysis is complete the next step can be executed is the design phase.
Stage design Design is making an application specification, the specification that
will be created with the following stages:
1.The design uses state transition diagrams 2. The design of the prototype
3. The design of the interface interface
3. Coding and Implementation
Designing for the return channel of MHP can be done once completed. Creating a
software return channel is required in accordance with the contents of coding to be
used on the return channel. Make the return channel only requires 2 software that is
NetBeans and Java. There are several things that must be considered in the use of such
software is
• NetBeans used to be versu 6.7.1 or more. This because there are several components
in NetBeans 6.7.1 needed to manufacture the return channel. This component is
absent in NetBeans with a lower version. One is called JavaServer Faces
frameworks
• For Java, there are 2 two types used JDK is JDK 1.4. and JDK 1.6. Each JDK has a
function each to run several different visual library.
• Visual Library run in accordance with the required program and on the run with the
corresponding JDK. If one library or the JDK does not work then the project will
not be able to run properly.
