Abstract

PT. Daux Cosmetic, an eyelash manufacturer located in Garut, Indonesia, faces challenges in optimizing the production mix of two eyelash models—Model A and Model B—under limited production and quality control time. This study aims to determine the optimal production combination to maximize profit using Linear Programming (LP). Two complementary approaches were employed: the graphical method for feasible-region visualization and the simplex method for iterative algebraic solution. Based on the LP formulation with objective function Z = 10,000,000X? + 4,500,000X? and two capacity constraints, the optimal solution was obtained at point B (X? = 10, X? = 60), allocating 10 hours to Model A and 60 hours to Model B, yielding a maximum profit of IDR 370,000,000. Both methods yielded consistent results, confirming LP as a reliable production-planning tool and a sound basis for operational decision-making.

Abstract

The use of computers as a tool for completing work in the field of information system technology is increasingly widespread and growing in all fields. Computers are felt to have many advantages, because computers can be programmed so that they can be adjusted to the wishes of the user. One way to get optimal results by managing data quickly and accurately is to use a computerized system and use system development, namely the Software Development Life Cycle (SDLC) with the Waterfall method in designing information systems, starting from analyzing software requirements, design, implementation, and Testing.Toko Agnia is currently still not optimal because sales and purchase data processing is carried out manually so it becomes ineffective. Based on the results of the reports that have been made, several conclusions can be drawn as follows: With the implementation of a desktop-based information system users will easily process sales, purchases and stock inventory, can speed up the processing and preparation of sales and purchases reports, the accuracy of calculations in this program can be relied upon.
