Abstract

The UMKM Keripik Umi is a micro-scale enterprise that produces banana chips but currently lacks a structured and systematic production planning approach. Production decisions are still based on historical demand trends, leading to inefficiencies, especially when customer demand fluctuates. This study aims to optimize production quantities, minimize total production costs, and maximize sales revenue for three product variants: original, balado (spicy), and chocolate-flavored banana chips. To achieve these objectives, the Goal Programming method is utilized due to its effectiveness in solving multi-objective optimization problems, especially when there are conflicting goals. The results of the optimization show that the ideal production quantities are 4,191 packs for the original flavor, 8,187 packs for the balado flavor, and 5,434 packs for the chocolate flavor. With this production allocation, the minimum total production cost is achieved at IDR 123,479,100, while the maximum projected annual sales revenue reaches IDR 54,640,900. These findings demonstrate that the Goal Programming method can be a valuable decision-support tool for Micro, Small, and Medium Enterprises (MSMEs), particularly in managing limited resources while pursuing multiple business objectives. By implementing structured production planning using this method, MSMEs like Keripik Umi can significantly improve their operational efficiency, adapt more effectively to market dynamics, and enhance profitability in a competitive business environment

Abstract

PT. IKI is a shipbuilding company owned by the Indonesian government which carries out several industrial activities such as ship building, repair and docking. The results of initial observations found that there were still workers in the production division who experienced work accidents and occupational diseases. In this research, it is very important to analyze the factors that influence the behavior of production division workers to find out what suggestions for improvements are appropriate in overcoming problems with production division workers. This research employs the SEM-PLS method to investigate the impact of knowledge factors (X1), attitudes (X2), and the availability of facilities (X3) on the occupational safety and health of production division workers. It aims to provide valuable insights for enhancing workplace safety by identifying factors that positively influence these outcomes. The findings of this study reveal a significant correlation between the availability of facilities (X3) and occupational safety and health, as evidenced by a p-value of 0.000, which is less than the predetermined significance level of 0.05. Based on these results, recommendations for improvement can be proposed. The company is advised to uphold and enhance the implementation of Standard Operational Procedures about Occupational Safety and Health (K3) while also ensuring the continuous provision of comprehensive Personal Protective Equipment (PPE) for all employees
