Abstract

PT. XYZ is a manufacturing company that operates in the field of fertilizer and non-fertilizer production with the aim of helping the country realize a food self-sufficiency program. It is known that PT. XYZ has problems with excessive machine downtime in its production process. Problems occur because there is repeated damage to the machine, activities that involve waste, so that the maintenance system on one machine has not been carried out optimally. The aim of this research is to analyze maintenance activities implemented in the Company and then minimize waste in maintenance activities using a lean maintenance approach. Downtime data collection was carried out in April 2024, then data processing was carried out using equipment effectiveness to see how effective the existing equipment was, then continued with Maintenance Value Stream Mapping (MVSM) to find out waste that occurred during the maintenance process, after the cause of the waste. is known, several suggested options are given to minimize the waste that occurs. From the implementation of the recommendations made, the machine equipment effectiveness value increased from 92% to 97%, the maintenance effectiveness value increased from 41.6% to 66.7%.

Abstract

This research aims to measure the supply chain performance of a furniture company located in Gresik Regency, namely UD. AZB. In its production process, not only growth occurs but the company also faces problems, including a lack of product marketing strategies and miscommunication between the owner and suppliers, the owner and workers, and the owner and customers. Supply Chain Operation References (SCOR) is the methodological approach used in this research. In addition, weighting was also applied to each core process, attribute, and Key Performance Indicators. Meanwhile, snorm de bour normalization was used to standardize the values of the Key Performance Indicators. The results of the production performance measurement of flooring furniture at UD. AZB obtained 14 KPIs. The production performance value is 84.58 good indicators. This research is expected to help improve the performance of UD. AZB by conducting evaluations and enhancements in areas that are still lacking in order to increase customer satisfaction.

Abstract

Tofu producer is a small and medium enterprise that produces white tofu in the food industry. In supply chain activities, many risks still disrupt the smooth running of industrial activities. These risks or disruptions include delays in the delivery of soybean raw materials, business owners having difficulty planning raw materials, disruption of the production process due to machine damage, and various other potential risks. Based on this, this research identified risk events and causes of risk events, as well as proposed mitigation actions that could be applied using the House of Risk (HOR) method. The research found 19 risk events and 20 risk risk agents. HOR 1 phase findings include that insufficient maintenance management posed the most significant risk. The poor maintenance led to the highest overall Risk Potential score. The HOR 2 calculation identified nine mitigation to minimize risks throughout the supply chain process

Abstract

This study aims to evaluate the risk of Musculoskeletal Disorders (MSDs) during manual material handling activities at Firm DCF's warehouse. Tasks such as lifting, moving, and arranging goods manually can cause risk due to non-ergonomic postures. The research began with observation and Nordic Body Map (NBM) questionnaires, followed by posture analysis using the Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) methods. The results indicate that the highest risk occurs during receiving and picking activities, with REBA scores of 11 and RULA scores of 7. This result shows the need for immediate corrective action. The primary contributing factors are bending postures, heavy loads, and repetitive movements. Recommended improvements include providing training on proper lifting techniques, using mechanical aids such as hand pallets or trolleys, and adjusting rack heights to match optimal reach distances. Implementing ergonomic risk principles is expected to reduce injury risks, enhance work comfort, and sustain productivity among warehouse employees at PT DCF.
