Abstract

This study aims to enhance the reliability of PT. XYZ Surabaya's rental fleet, which experienced numerous incidents of damage to Avanza units from 2019 to 2023. The Westinghouse analysis method was employed to determine repair intervals and calculate the Mean Time to Failure (MTTF) for component replacements. The findings revealed that the oil filter and clutch assy components were the most frequently damaged. The oil filter requires replacement every 1460 hours (60 days) with a reliability of 52.31%, while the clutch assy needs replacement every 3429 hours (142 days) with a reliability of 46.78%. The performance of mechanics in replacing these components was also analyzed to improve efficiency. This study assists PT. XYZ in minimizing downtime, extending component lifespan, and enhancing operational efficiency, ultimately contributing to customer satisfaction and the sustainability of the vehicle rental business.

Abstract

This study aims to analyze the content of DSN MUI Fatwa No. 116/DSN-MUI/IX/2017 on Sharia electronic money from the perspective of qiyas, focusing on the case of the LinkAja Syariah application. The research method used in this study is descriptive qualitative, and the approach employed is library research. The findings of this study indicate that the LinkAja Syariah application is a development model of the LinkAja application designed to facilitate transactions while adhering to Sharia principles in its operational system. Similarly, the transactions follow the principles of cash payments and interbank transfers in Sharia banking, implementing Sharia financial principles. Thus, using the digital wallet application through LinkAja Syariah is legally permissible (mubah) as it fulfils the requirements and conditions of qiyas.

Abstract

This study aims to analyze the physical and mental workload and their influence on work fatigue and musculoskeletal disorders among employees at CV XYZ, a metal fabrication company characterized by high operational intensity. Data were collected through direct observation, interviews, and questionnaires, including physical workload measurement using the Cardiovascular Load (CVL) method, mental workload assessment using the NASA-TLX method, work fatigue evaluation using a 30-item fatigue questionnaire, and musculoskeletal disorder assessment using the Nordic Body Map (NBM). The results showed that the average physical workload was categorized as moderate, with a CVL value of 53.31%. Meanwhile, the mental workload was found to be very high, with an average score of 82. The level of work fatigue after performing tasks reached an average score of 81, classified as high, indicating significant fatigue accumulation among workers. Additionally, musculoskeletal complaints yielded an average score of 34.45, categorized as moderate, with two workers experiencing high-risk symptoms. These findings indicate that employees exposed to substantial physical and mental demands that contribute to increased fatigue and musculoskeletal complaints. Therefore, ergonomic interventions, workload adjustment, and improvements in work conditions are essential to reduce fatigue levels and enhance worker well-being and productivity.

Abstract

This study analyzes physical workload and work-time efficiency in the tofu production process at UD Asal Lancar, where operations are still performed manually. A total of 12 production workers were included as research samples. Physical workload was measured using the Cardiovascular Load (CVL) method, work-time efficiency was evaluated through the Work Sampling method, and the optimal number of workers was determined using Work Load Analysis (WLA). The results show that the highest workload occurred in Worker 7, who recorded a CVL value of 53%, categorized as a heavy workload, while other workers fell into light to moderate categories. Work-time efficiency was found to be 84%, lower than the standard due to reduced effective working time caused by unproductive activities. The study recommends task redistribution, implementation of regular micro-breaks, and additional manpower in certain stages to balance workloads and improve work efficiency.

Abstract

This study discusses several ways to accelerate the building construction process. The study used two methods, namely crashing and overlapping. The crashing method involves adding overtime hours and labor to shorten the project duration. Meanwhile, overlapping is rearranging the relationship between tasks so that they can be done simultaneously without reducing the initial time, thus accelerating completion at a relatively comparable cost. The analysis results show that both methods are effective in accelerating projects, with the overlapping method requiring less cost and providing greater time reductions. The choice of the best method depends on budget constraints and the project's completion time requirements. Thus, this acceleration strategy can help project management in achieving time targets at an optimal cost.
