Optimization of Hijab Production Profits for UMKM Saveer Hijab Using the CPLEX Application

Introduction

Optimization of hijab production profits for umkm saveer hijab using the cplex application. Optimize hijab production profits for MSME Saveer Hijab using CPLEX. Determine optimal production volume for Malay Scarf & Pashmina Square to achieve max profit of IDR 7,000,000.

Abstract

Micro, Small, and Medium Enterprises play a major role in economic growth in Indonesia and must continue to be supported and developed in order to compete at a global level. Saveer Hijab is one of the hijab fashion brands in the MSME sector that produces various types of hijab. Saveer Hijab experienced a decline in sales because the number of requests was not balanced with production costs due to the increase in raw material prices. This study aims to formulate an optimization model to determine the optimal production volume so that maximum profit is obtained using the CPLEX application. The results of the study showed that to optimize profits, Saveer Hijab must produce 200 pcs of Malay Scarf hijab and 120 pcs of Pashmina Square hijab. Thus, the profit obtained by Saveer Hijab is IDR 7,000,000.00 or 75%. Saveer Hijab obtains maximum efficiency for the amount of fabric and thread inventory, because in the production process of both types of hijab, it requires a fabric inventory of 500 m and a thread of 800 m, which is in accordance with the amount of material availability capacity. Furthermore, the amount of plastic packaging inventory still leaves 180 pcs because in the production process the amount of plastic used is 320 pcs.

Review

This paper presents a timely and relevant study addressing the challenges faced by Micro, Small, and Medium Enterprises (MSMEs) in Indonesia, specifically focusing on the Saveer Hijab brand. The core problem—declining sales due to increased raw material costs and an imbalance between requests and production—is a common issue for many small businesses. By employing the CPLEX application to formulate and solve an optimization model, the study aims to determine the optimal production volume for maximum profit. The abstract clearly articulates the problem, methodology, and key findings, making a direct link between quantitative analysis and practical business solutions. The study offers a valuable contribution by showcasing the practical application of advanced optimization techniques for a real-world MSME. The concrete recommendations to produce 200 units of Malay Scarf hijab and 120 units of Pashmina Square hijab, leading to an IDR 7,000,000.00 profit, provide actionable insights for Saveer Hijab. Furthermore, the paper highlights efficient resource utilization, demonstrating that the optimized production plan effectively uses all available fabric and thread, thus minimizing waste and maximizing efficiency for key inputs. This direct translation of optimization results into tangible business decisions and resource management is a significant strength. While the study provides clear recommendations, a few areas warrant further detail and consideration. The abstract mentions a profit of IDR 7,000,000.00 "or 75%"; this "75%" needs clearer context—is it a profit margin, a percentage increase from previous profits, or another metric? Understanding the full scope of the optimization model, including all constraints beyond just fabric, thread, and plastic packaging (e.g., labor, production capacity, market demand, sales channels), would enhance the study's robustness. Future work could benefit from sensitivity analysis to explore how profit levels and optimal production volumes change with fluctuating raw material prices or varying demand. Additionally, a brief overview of the model's structure (objective function and key constraints) would increase the transparency and replicability of the findings for other MSMEs facing similar challenges.
