This paper discusses the case of PT Bintang Permata Sejati, a garment manufacturing company that faced multiple labor accidents at the buttonhole stations over a five-month period. The absence of occupational health and safety management practices within the company made it challenging to address these incidents, resulting in the temporary suspension of the production process and significant expenses for the corporation. To resolve this issue, the company employed the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) design, which involves analyzing and solving problems in three stages. By implementing solutions such as using iron gloves, duct tape insulation, cable ties, taking advantage of relaxation breaks, and changing chairs, the company successfully identified and addressed 17 problems related to people, materials, methods, machines, and the environment, of which 8 were low-risk, 3 were medium-risk, and 6 were high-risk. The cost of implementing these measures was significantly less than the profits earned by the company, highlighting the importance of maintaining an up-to-date HIRARC design and conducting research on its effectiveness. This case underscores the significance of occupational health and safety practices in reducing accidents and promoting employee welfare in manufacturing companies.

Metro Musik is a well-known music equipment store in Malang City that also provides music education services. This service quality research was conducted because Metro Musik assessed that the decline in business was not only caused by the pandemic but also by customer dissatisfaction with the services provided by Metro Musik, based on criticism from buyers about the quality of service at Metro Musik Malang. This study aims to identify service quality using the Servqual method, prioritize service quality improvements using the Importance Performance Analysis (IPA) method, propose improvements using the Quality Function Deployment (QFD) method to improve service quality, and measure service quality at Metro Musik Malang after improvement efforts have been implemented. Based on the GAP 5 calculation, it was found that none of the attributes met customer expectations, or the quality of service at Metro Musik Malang was considered inadequate. Then, based on the IPA analysis, four attributes were prioritized, namely attributes number 2, 8, 10, and 11. Five improvements were proposed for the four prioritized attributes, including training employees to be more responsive in serving customers, creating reminders with detailed schedules, displaying realistic product photos, explaining corresponding product specifications, planning to add 1 to 2 employees, and renovating the store. However, only three out of the five proposals were implemented. The results of the implementation provided a 35% increase in customer satisfaction with the quality of service at Metro Musik Malang. Attributes number 2, 8, and 10 experienced an increase in customer satisfaction, but attribute number 11 experienced a decrease.

Efficiency and quality are two crucial factors in the manufacturing industry in Indonesia. PT. SASL and Sons Indonesia is a manufacturing company in the coconut processing industry, with various stages of production separated into different rooms. However, the production room layout was found to be inefficient due to the distance and size between the rooms, which affected the flow of material movement. To address this issue, the Computerized Relationship Layout Method (CORELAP) was used to redesign the layout of each production room and improve the flow of material movement. Factors considered in the redesign included the sequence of production processes, the distance of material movement, and the dimensions of the machine and material handling equipment. The new layout resulted in a material movement distance of 53.963 meters, a reduction of 86.7% from the initial layout's distance of 406.75 meters. This study demonstrates the importance of optimizing production room layout for improved efficiency and material movement, which can ultimately lead to better quality products and customer satisfaction.

Publisher : Teknik Industri Universitas Ma Chung

This study examines the delayed development of the Soekarno Hatta-Tangerang Airport Accessibility project due to the Covid-19 pandemic, particularly in the construction of the main bridge. To address the delay, work optimization was carried out using the Critical Path Method (CPM) and project crashing method. Two optimization alternatives were identified: increasing working hours (overtime) and shift work. The research results show that both alternatives can perform crashing in 118 weeks, but there is a difference in direct cost. By using the alternative of increasing working hours, there is an additional cost of Rp 1,455,346,223.78, while by using the shift work alternative, the additional cost is Rp 1,562,626,223.78. The value of indirect cost is the same because the crashing duration is the same, and the direct cost increases because the crashing calculation is based on time and workers on the ground. Therefore, optimizing the main bridge construction work by increasing working hours is the alternative that suits the owner's request because the cost and duration calculations are in line with the owner's request. The findings of this study can help other construction projects facing similar challenges caused by the pandemic to determine the most appropriate optimization alternative. Keywords

This research aims to minimize waste and increase revenue by utilizing soybean waste in the form of soybean skins and cooking water to produce Tempeh flour and Nata de soya. The study was conducted at Amanah where approximately 50-60 kg of solid waste and more than 45 liters of liquid waste are generated every day. The waste was collected, analyzed, and processed using a business design analysis method. Data were collected through interviews and observations with the owner of Amanah. The financial aspect of the business plan was evaluated using the payback period (PP), net present value (NPV), and internal rate of return (IRR). The results showed that the business plan had a PP of 2.58 years and was considered feasible with an NPV of $42,321,728.56 and an IRR of 56%, which is higher than the minimum acceptable rate of return (MARR) of 17.1%. This research provides a solid foundation for Amanah to develop the project further in the future. Therefore, this study is expected to be useful for other Tempeh industries that want to minimize waste and increase their revenue through waste utilization.
