DISCUSSION

5.1 System Design
Electrical System Design Billing Information can facilitate in the calculation of billing KWH of electricity bills because the data already entered or previously entered first. so, if we want to find customer data or data items can press the button that has provided the data that we need will appear by itself.
Stage - the design phase of this system include:
a. determination Formulas
b. designing DataBase
c. designing interfaces

5.2 Determining the Formula
Before applying the code to the user interface System Information necessary to determine the formula for calculating kwh electricity bills, the formula - a formula that is used as follows:
a. KWH formula → 1 item
usage = Watts * hours of use
KWH = usage / 1000 * 30

b. Formulas KWH → 2 items or more
use of (a) = a * Watts goods usage hours a disposable item
usage (b) = b * Watts goods usage hours disposable goods b
KWH = (a + consumption goods consumption goods b) / 1000 * 30
5.2.1 Calculate Process
a. If KWH ≤ 30 then, pay = KWH * 169
b. If KWH> 30 to ≤ 60 then, pay = (30 * 169) + (KWH - 30 * 360)
c. If KWH> 60 then, pay = (30 * 169) + (30 * 360) + (KWH - 60 * 495)
Cost = power * 11
Total = (pay + expenses) * 1:04
5.2.2 Process Deviation
a. Max power consumption = 400 * / 1000
b. Min power consumption = 180 * / 1000

5.3 Design DataBase
In Designing Database Software required DBMS (Data Base Management System), which is used in the design of applications systems Billing Information Sepatan Electricity in the service area is Oracle.
This database consists of several tables contains a field - the field required in the design of Information Systems.

5.3.1 DFD (Data Flow Diagram)
DFD describes the data flow from the PLN as a source of data providers (input) to consumers PLN as the recipient of the data (output).

5.3.2 normalization
• Form Unnormal
Is a table consisting of all the fields that will be used in an Electric Billing Information System database
• 1NF

 
In each slice of the column and each row has a value of data - each.

 • 2NF
All fields depending on nomor_pelanggan, because nomor_pelanggan is as key

 • 3NF
At this stage of 3NF is eligible to be a relation scheme.

5.3 Designing the interface
In making the user interface writers to use software tools for Microsoft Visual Basic 6.0 Implementation and design looks.
5.3.5 Design Input
Electricity Billing Information System design requires input that serves to incorporate customer data into the Computer System.

5.4 Implementation Results
The results of implementation contained in the Application of Electricity Billing Information System are as follows:
1. When Customer Complaints

OPEN SOURCE

Choosing suitable software for education is not just done by comparison of the functional features of perangkar software. Moreover, just choose the software that is popular in industry and taught its users among students. For elementary school students, the software selection should be more careful. Aspect of education should be a primary consideration, not only pragmatic and economical.

     As an example of the type edutainment software, namely an educational software that is entertainment. software is intended for children so hopefully the process of studying a material can be fun. Unfortunately when choosing this edutainment software, often the focus is more directed than the quality of the graphics or sound educational values ​​behind the use of the device lynak. pertimabangan edukasinya value is not just learning the material presented, but more than that, those things that educate formed due to the use of software in the classroom.

     Values ​​in education are more often forgotten when considering the use of educational institutions of open source software or proprietary. consideration of educational value that makes the educational institutions abroad, instead of taking such devices are already ready to use edutainment (system and material), choose to use your device Squeakataupun Sophie lunakopen source such as a multimedia environment for children's learning. Teachers with proteges building edutainment software.

      Knowledge and educational aspects in a very difficult ataslah obtained using the software propeitary in education. so that for basic education, then the choice of the use of open source software seems to have pointed in the right direction. It was originally like a hassle, but in teaching and learning, where there is no hassle. Pengguanaan open source will provide added value to the educational process, both for educators and for students. not to mention including the teaching of intellectual property rights from the beginning. One thing that is overlooked in basic education in Indonesia.
