Abstract

The increase in demand for crackers during the Ramadan period requires optimal labor management to keep production efficient. This research aims to determine the optimal number of workers to maximize cracker production. The method used is linear programming with a simplex approach, with data obtained through interviews and processed using MATLAB. The model is formulated with a decision variable in the form of the number of workers at each stage of the production process. The purpose function is formulated to maximize total production by considering capacity constraints, operational time, and labor costs. The results of the study show that the optimal solution is obtained in . The maximum value of the objective function obtained is 80kg/day of production or equivalent to a 300% increase in cost efficiency per kg of Rp333.33. The allocation shows the most efficient distribution of labor in meeting resource limitations. Further research is recommended to consider dynamic demand factors and variations in production capacity.

Abstract

“Es Kul-Kul” production business located in a shop called the Muawanah Cooperative, is experiencing difficulty in maximizing profits due to changing consumer demand and challenges in determining the supply of raw materials needed. The owner continues to produce “Es Kul-Kul” based on the average daily consumer order, thereby sacrificing the efficiency of utilizing raw materials and capital. This study aims to analyze production planning to maximize profits from the sale of “Es Kul-Kul” at the Muawanah Cooperative UMKM using the simplex method. The research method employed in this study is a case study, with data analysis and processing conducted using linear programming, specifically the simplex method. The results of the study showed that the optimal production combination consisted of 50 banana-flavored skewers, and 100 strawberry-flavored skewers, with a total profit of IDR 800.000 per day. This approach has succeded in increasing production cost efficiency and optimizing profits, which is relevant for application to other UMKM. Possible further research is research based on optimization problems that occur in the surrounding environment with different methods and more detailed instruments to produce more accurate and realistic research.

Abstract

This study aims to optimize production planning at UMKM Mie Ratu Situbondo, particularly for two main products, namely Mie Ratu Galak and Mie Ratu Ganas, in order to maximize daily profit and reduce inefficiencies in the use of raw materials. The background of this research is the production decision-making process that is still based on estimation, which often leads to suboptimal results and potential waste. The research method used is linear programming with the Simplex method, followed by the Branch and Bound method to obtain integer solutions. Data were collected through observation and interviews with the business owner over a period of more than seven days and were aggregated into daily average values. The analysis was carried out using MATLAB software. The results show that the optimal production combination is 63 portions of Mie Ratu Galak and 67 portions of Mie Ratu Ganas per day, resulting in a maximum profit of Rp1,434,000 per day. Compared to the previous condition, this result indicates an increase in profit and a more efficient allocation of resources. This study provides practical benefits for UMKM actors by offering a systematic and quantitative approach to production planning, which can support better managerial decision-making and improve business performance.
