DEVELOPING ACHUSI SYSTEM AS BUSINESS SYSTEM SOLUTION

FOR C.V. X

(SALES, INVENTOR Y, AND ANALYSIS SUBSYSTEM )

Abstract

  This paper is a summary about our thesis that is about making information system for a consumer goods distributor company. The major problem of the company is the transaction is still done in paper based and incomplete/unorganized historical database.

  In making the thesis we are using modified waterfall model as the system development life cycle. Using that SDLC the business software is made including the hardware architecture as the place to run the software. The modules of the software are separated into three parts for the three members of the groups while the other part such as analysis and design is made together by the three members of the group. Those three parts of modules are Inventory and Sales (including sales transaction and analysis) subsystem will be made by Danie Susanto; Accounting (including account receivable and account payable) subsystem will be made by William Hartanto; and Utility, Cost, and Bonus subsystem will be made by Willy Suryadi. Those modules are made on top of C# Language in Windows Form and using Microsoft SQL Server Express as the DBMS.

  Besides that, the new business system is made to improve the business process to use the software in day to day transaction. In this new business system, new posts are created such as logistic manager, sales manager, and accounting manager. Another new post are administrator that is intended for inputting the day to day transaction and warehouse person as the man who is responsible for stocks in the warehouse.

  By making software, preparing the hardware, and the new system to run the business daily activities, the company’s business process will move one step forward in this information era.

PREFACE

  At the first, I want to thank God for his guidance and blessings so that I can finish the thesis on the schedule with the expected result. This thesis is made as the final duty to graduate from Bina Nusantara University and gain Sarjana Komputer Degree majoring in Computer Science.

  One of the purposes of this thesis is to implement what I have learnt during his study in Bina Nusantara University and also learns new things before I start my career.

  I would also like to express my gratitude to all of those who have helped me whether it is directly or indirectly in completing this thesis:

• Bina Nusantara University which provides me with the facilities to complete my thesis.
>Erwien Nurwihatman, M.Kom as my thesis supervisor who always support and guide us how to make a good thesis until the last mom
• Ir. Tri A. Budiono. M.I.T., as Head of School of Computer Science, Binus

  International, Universitas Bina Nusantara who issues the thesis rules as the guidance for me and team members in developing the thesis.

• Mr. Kiki Purwanto as my project sponsor, the one who gives the requirement, verifies the system, and shares his business knowledge.
• Mr. Raymondus Kosala Phd., Mr. Yahya H. Msc., Mr. Adrianus Haryo MSCS.,

  Mr. Totok Soefijanto Phd., Mr. Abu Bakar Siddiq, and all other lecturers who have helped and shared their knowledge with me and team members.

• Aida Wiguna, MM. my aunt who shares her knowledge about business.
• All the staff of University of Bina Nusantara who give their support in the thesis period.
• My family who always give their pray and support.
• My group members who were willing to work with me and helped each other almost everyday whether it is on campus or in the one of the group member’s house from the start to the end of the thesis period.
• All other friends who have supported and helped me during the thesis development.

  Final words, this thesis is devoted to the company in order to have a better system in day to day transaction and as the example for those who wants to develop information system solution with .NET Programming Language and using Waterfall SDLC.
