Abstract

Home-industry is a job that depend on human labor. Coconut milling is a home-service which is depend on manual material handling through production process services. Early result based on Nordic Body Map questionnaire (NBM) exposed that coconut milling operators had skeletal muscle complaints, so an ergonomic risk evaluation was needed to prevent skeletal muscle disorders. The purpose of this study is to evaluate ergonomic risk in order to prevent coconut milling operators from being affected by musculoskeletal disorders. Workplace Ergonomic Risk Assessment (WERA) and Job Strain Index (JSI) are ergonomic approaches that are used based on the risk of repetitive motion, vibration strength, contact stress and task duration involving five main areas of the body, namely shoulders, wrists, back, neck and legs which can cause Musculoskeletal Disorders. The results showed an improvement in working posture which initially had a WERA value of 44 for operator 1 and 45 for operator 2, then improved to 27 at the low level. Furthermore, the improvement of working posture in the neck should be in a position of 10°-20° at medium level and moderate movement with multiplied pause activities. Conditions for improving work activities at the JSI value of 9 for operator 1 and 20 for operator 2 were then improved to 4.5. Improved working posture, namely in operator 1's wrist which is too bent, it is recommended for operator 1's wrist not to form an angle of less than 15° to reduce the risk.

Abstract

This Community Service Program was carried out in Tenggor Village with the aim of improving the productivity and efficiency of catfish farming through the application of the biofloc system. The biofloc method was selected for its ability to utilize microorganisms to convert organic waste into natural feed, thus reducing feed costs and maintaining water quality. The program was implemented using a participatory approach, involving stages of field surveys, socialization, technical training in biofloc pond construction, cultivation assistance, and evaluation for sustainability. The results show the successful construction of one biofloc pond with a capacity of 1,000–1,200 fish, an increase in community knowledge from 40% to 85%, faster growth rates with a survival rate of 90%, and operational feed cost efficiency of 20–30%. In addition to its economic benefits, the program strengthened community cooperation and improved entrepreneurial awareness. These outcomes indicate that the biofloc system has strong potential to be expanded as a model for sustainable local economic development based on aquaculture.

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.
