Abstract

The distribution of sulfuric acid raw materials is still conducted conventionally and faces challenges regarding the quantity of supply for each product. Therefore, this research was conducted to help create a mathematical model for the distribution of sulfuric acid using the Goal Programming method with the assistance of LINGO 18.0 software. Goal Programming serves to minimize deviations from limits and targets based on priorities in order to maximize profit and achieve the optimal quantity of sulfuric acid in the distribution of sulfuric acid raw materials, as well as to supply several fertilizers containing sulfuric acid. The research results indicate that the annual sales revenue target of 982,937,304 USD was achieved without any deviations. Most of the optimal production targets for products X1 to X8 were also met, with deviation variables showing no shortfall in production quantities for these products. However, for product X2, there remains a production shortfall of 60,096.15 tons to reach the target of 405,823 tons.

Abstract

Muscle fatigue can cause problems or musical symptoms. The problem of musculoskeletal can be affected by such factors as energy, posture, action over and over - again, and longer working hours, with a 20% delay production percentage. It aims to analyze the body posture and mental workload on the production operator. The study's sample removal was made of 15 production operators at the XYZ corporation. The purpose of the study is, to know the impact of body posture, evaluate the risk factors of less-ergonomic working posture, and know the category of mental workload experienced by production operators at the XYZ pt. The data analysis techniques used in this study are Reba and MCH analysis. Research results by using the Reba method score 7 which means moderate risk work if carried on a long period, and changes need to be made immediately. On MCH methods obtained underload job classifications on purging and refining activities, installment of the plate, end of the plate, final fitting, casting, finishing, shipping, release of the product, PC strand cutting, and removal of the product. Whereas an optimum classification load on the scrounging activities section. Overload classification is the installation, spiral, and PC strand, and early 20% stress.

Abstract

CV. Central Karya Jaya, a rice distribution company, faced a 40% profit decline. This study aims to enhance company performance and customer satisfaction using the Balanced Scorecard and Importance Performance Analysis (IPA). Data from 70 respondents showed a financial ROE above 12%, but customer satisfaction had a 72.25% conformity, revealing unmet needs. Key improvements are needed in managerial friendliness, employee responsiveness, and personalized service. Recommendations include fostering better employee relations and understanding customer needs, with future research suggesting the use of Quality Function Deployment (QFD) for further service enhancement. Highlights: Financial Performance: ROE above 12% indicates solid financial health. Customer Satisfaction: 72.25% conformity shows areas needing improvement. Key Improvements: Enhance managerial friendliness and employee responsiveness Keywords: Performance Measurement, Balanced Scorecard, Customer Satisfaction, Rice Distribution, Importance Performance Analysis

Abstract

UKM Gudang Dompet is a company that produces wallets. The number of orders will affect employee performance because the number of targets achieved will increase the workload for employees, causing fatigue. To prevent excessive fatigue felt by workers in the production division at the Dompet Warehouse, it is necessary to measure workload. The Full Time Equivalent (FTE) method measures working time, which is based on working time, measuring the time needed to complete a particular task and then converting it into an FTE index value. The cardiovascular load (CVL) method measures physical workload based on comparing pulses. Working pulse with a maximum pulse. This research showed that worker fatigue occurred in the packing section, indicated by a CVL value of more than 30%, so FTE calculations were carried out to determine energy consumption. Based on energy consumption calculations, the results obtained are an additional rest time of 32.85 minutes in the packing section. Keywords: workloads; full-time equivalent; CVL; work system design.
