Abstract

The main problem at UD. Fazal Tani lies in the inefficiency of transaction processes and inventory management, which are still carried out manually, often leading to recording errors, delays in reporting, and inaccurate stock data. This study aims to develop and implement an Android-based Point of Sale (POS) system using the Mandatory, Desirable, Inessential (MDI) approach to effectively and efficiently identify and prioritize system feature requirements. The research method employed is qualitative descriptive through observation, interviews, and literature study, while the system development follows the Waterfall method with stages of requirement analysis, design, development, testing, and maintenance. The implementation results show that the developed POS system is capable of handling sales transactions, inventory management, receipt printing, and sales reporting in a more structured and faster manner. Black box testing indicates that all functions operate as expected. The application of the MDI method focuses system development on the main features required by users, reducing the average transaction time from 30 minutes to 4 minutes, achieving an efficiency of 86.67%.

Keywords: Point of Sale, Mandatory Desirable Inessential, Information System, Android, Inventory Management.
