Abstract

Background: Tempeh Micro, Small, and Medium Enterprises (MSMEs) are largely home-based industries that rely on manual production processes. These manual tasks often involve inefficient movements, leading to musculoskeletal disorders and significant work fatigue. Objectives: This study aims to implement a Lean Ergonomics approach to reduce motion waste, musculoskeletal complaints, and work fatigue among workers in the tempeh industry. Method: This experimental study used a within-subject design (treatment-by-subject). The research was conducted in two phases: before improvement (P1) and after improvement (P2). Data collection involved identifying waste, analyzing work posture using the Rapid Upper Limb Assessment (RULA) and Rapid Entire Body Assessment (REBA), measuring musculoskeletal complaints via the Nordic Body Map (NBM), and assessing fatigue levels using the Industrial Fatigue Rating Committee (IFRC) questionnaire. Results: Interventions included redesigning worktables to improve posture, implementing the 5S methodology to refine work methods, and optimizing the facility layout. The results demonstrated a significant reduction in unnecessary movements, decreasing from 15 in P1 to 7 in P2. Work posture scores improved, with RULA and REBA scores decreasing by 1.81 and 2.87, respectively. Furthermore, musculoskeletal complaints decreased by 22.4% (9.31 points), and work fatigue levels were reduced by 22.14%. Conclusion: The application of Lean Ergonomics effectively reduces motion waste, improves work posture, and lowers levels of musculoskeletal pain and fatigue. These improvements enhance overall work comfort and performance within tempeh MSMEs.

Abstract

Currently, there is a growing trend of processed foods made from natural and healthy ingredients. One such ingredient is cassava, which provides good nutritional value. Additionally, this ingredient is tasty, affordable, and readily available in local communities. One of the residents of the Special Region of Yogyakarta is the community of Kalijeruk I and II Hamlets. This community has abundant cassava resources in its area because the hamlets still have many rice fields. However, the women in this community have not yet produced a variety of processed cassava products. Therefore, these women need to learn more about the different types of processed cassava products. A team of lecturers and students from the University of AKPRIND Indonesia carried out this community service activity. The activity was divided into several stages: first, socialization about the competition; second, the cooking contest; third, food presentation; fourth, food evaluation; and fifth, announcing the winners. This event provided the mothers with basic knowledge and motivation to create delicious, nutritious, and economically valuable cassava-based dishes. This was demonstrated by the 12 different cassava dishes prepared by the mothers.
