Abstract

In order to produce delectable, nutritious and affordable pricing, tofu products go through a labor-intensive manufacturing process that demands physical exertion and muscular vigor. In Indonesia, particularly in Semarang, Central Java, the tofu manufacturing process is still carried out manually, including the handling of raw soybeans and finished tofu, generally called Manual Material Handling (MMH). Among the tasks performed by MMH workers include lifting soybean, holding soybean extraction, lifting and carrying tofu barrels. Lifting loads range from 10 to 70 kg. The objective of this paper is to assess the degree of ergonomic risks and complains among MMH workers. The method used is quantitative analysis with a cross-sectional research design that refers to SNI 9011: 2021. Research methods to collect data include observations, interviews, and surveys. 80% of respondents complained of experiencing pain. Painful body parts with a high level of frequency and severity are located in the neck, right shoulder, upper back, lower back, arm, and right hand. A score of 9 indicates a high-risk level for MSD concerns. The total score of potential ergonomic risks is in the range of 11–19, with body scores vary from 2 and 8, material handling scores is 8. In order to reduce the risk of ergonomic hazards in MMH activities, risk control efforts are carried out by dividing the load into acceptable limits, lifting loads balance on both sides of the body. Providing assisting devices, such as ergonomic hand trolleys, can handle huge amounts with fewer frequent material handlings. Counseling is carried out for workers to help them because more aware and knowledgeable about how to conduct MMH activities safely.

Abstract

Time measurement is carried out to determine the length of time required for workers to complete the production process, starting from raw materials to finished goods. Due to the low production volumes, the Barokah Tegal Tempe Home Industry's tempeh production process is not producing optimal results, which prevents them from fulfilling customers’ demands. Limited production capabilities due to lengthy processing times. Extended processing durations may result from non-value-adding movements or activities, as well as manual labor techniques. The aim of this research is to examine the tempe production process, with a focus on the three primary work stations—the peeling, washing, and mixing operations. The method used is the Maynard Operation Sequence Technique (MOST), where measurements are carried out on existing conditions and proposed work improvements. The research results show that the existing time measurement in the peeling process is 104,840 Time Measure Units (TMU), washing 316,020 TMU, and mixing 127,360 TMU. In order to reduce processing time, work tools should be able to do away with pointless movements. The proposed work improvement time for peeling process is 60,680 TMU, washing 93,800 TMU, and mixing 50,300 TMU. Calculations of the existing condition and proposed improvement can result in a 62% increase in working time efficiency.
