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.

Abstract

Occupational Safety and Health (OSH) plays a critical role in maintaining safe and sustainable production, particularly in small-scale agro-industrial operations such as coffee processing. This study applies the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) framework to evaluate workplace hazards at Kopi Lanange Jagad, a micro-scale coffee producer in Malang Regency, Indonesia. Field observations and structured interviews were conducted to identify potential hazards across four production stages roasting, grinding, sieving, and packaging. Quantitative measurements were also taken, including ambient temperature, noise level, and airborne dust concentration, to provide empirical data for risk evaluation. The findings identified a total of 12 hazards, classified into three risk categories: high (25%), moderate (50%), and low (25%). The roasting process exhibited the highest risk score (R = 18.4), with average workplace temperatures reaching 85°C–120°C, significantly exceeding the national occupational limit of 30°C for moderate workloads (Permenaker No. 5/2018). The grinding stage also presented considerable hazards, with airborne dust concentrations averaging 2.4 mg/m³, approaching the Ministry of Manpower’s threshold limit value (TLV) of 3 mg/m³. Manual packaging was associated with ergonomic strain, where workers lifted 15–20 kg sacks repeatedly, leading to potential musculoskeletal disorders. Risk evaluation revealed that existing control measures such as natural ventilation and sporadic use of personal protective equipment (PPE) were insufficient to ensure worker safety. To reduce these hazards, the study recommends implementing engineering controls such as local exhaust ventilation and machine insulation, combined with administrative measures including job rotation, scheduled rest breaks, and regular safety training. Ensuring consistent PPE use especially heat-resistant gloves, dust masks, and ear protection can further mitigate residual risks. Overall, the application of the HIRARC framework at Kopi Lanange Jagad demonstrates its effectiveness as a low-cost and practical tool for identifying, prioritizing, and managing occupational hazards in small-scale coffee industries. Implementation of the proposed control strategies is projected to reduce total workplace risk by 35–40%, improving both worker well-being and operational productivity.
