Abstract

UD. X is a distributor of LPG and mineral water located in the Sukoharjo area. Currently UD. X has not implemented information system technology in recording goods data, causing discrepancies in the actual inventory data. Inventory data discrepancies occur three to four times a week. To overcome these problems, it is necessary to have an information system that can make it easier to store data. The design of information systems begins with making ERD, context diagrams, and DFD. After that, it is continued by calculating the optimal order interval and calculating the minimum and maximum inventory needed by UD. X. Then proceed with making an information system application based on Microsoft Excel. The final result of the design of the information system is an application that has been designed to make it easier for admins to record accurately the inventory of goods and assist the owner in supervising the activities in and out of goods.

Abstract

SPP is a section of PT X manufacturing that produces packaging. KPI (Key Performance Indicators) of SPP are safety and sustainability, quality, delivery, and cost. Cost is divided into DIM (direct material) waste and productivity. DIM waste data percentage is recorded in the SPP production information system, including production report and material report. The problem is there is gap between the percentage of DIM waste in the production report and in the material report. This is caused by the three weaknesses of the SPP production information system. The SPP information system is not simple, the records are inaccurate, and not standard. The design of a new production information system is carried out in order to amend the weaknesses of the old production information system. This can support the company to minimize the gap between the percentage of DIM waste in the production report and in the material report results.
