The aim of this study is to control the production and reduce the company’s production costs at Rail and Query (RAQUER) by using information system implementation. This study found the problems that arise in production activities, causing leakage of high production costs in RAQUER. RAQUER is a medium-scale cottage industry engaged in the business of bag-making convection. This study was conducted by applying a qualitative descriptive approach and system development using a prototype model. System development included the identification of needs, data modeling, interface design, and application models. System testing was done to meet user needs that had been obtained from the identification of needs. The results achieved from this study are systems that able to control the production of bags at RAQUER so they can create production costs that are used more efficiently. If RAQUER is able to control its production process through this information system, cost efficiency can be achieved because there is no more random and useless production.
