Oil Palm Empty Fruit Bunch (OPEFB) is biomass by-products from palm oil processing mills. The cellulose content in OPEFB, which reaches 38.70%, presents a potential raw material for various cellulose-based products, such as nanocrystalline cellulose (NCC). NCC can be used as a raw material in various industrial sectors, including paper, packaging, food, pharmaceuticals, cosmetics, and electronics industries. The bioprocess technology for producing nanocrystalline cellulose from OPEFB has been successfully developed and is expected to be applied on an industrial scale. Therefore, an economic feasibility analysis is required to evaluate investment viability and the impact of parameter changes on investment using sensitivity analysis for the production of nanocrystalline cellulose from OPEFB with bioprocess technology. Based on the data processing of investment feasibility analysis with assumptions of cost data and other parameters using Internal Rate of Return (IRR), Net Present Value (NPV), and Payback Period (PP), it was found that the industry is feasible and profitable with an IRR of 113.99%, NPV of $763,804,208.84, and a Payback Period of 1 year. Additionally, using sensitivity analysis, it was determined that to maintain investment viability, the raw material price can only increase by a maximum of 35%, the product selling price can only decrease by a maximum of 15%, and production costs can only increase by a maximum of 20%. This research is expected to provide information to stakeholders such as investors, government, and industry regarding the opportunities for developing nanocrystalline cellulose production from OPEFB in Indonesia. Keywords: nanocrystalline cellulose, techno-economic study, oil palm empty fruit bunch, bioprocess technology

Improper working postures are one of the main causes of Musculoskeletal Disorders (MSDs), particularly in manual and repetitive tasks such as packaging operations. This study aims to analyze the ergonomic risks associated with workers’ postures at the packing station of an oleochemical company and to propose corrective measures to reduce potential MSDs. The assessment employed two ergonomic evaluation methods: Rapid Entire Body Assessment (REBA) to determine posture risk levels and the Nordic Body Map (NBM) questionnaire to identify body regions experiencing discomfort. The results revealed that Worker A obtained a REBA score of 8, indicating a high-risk level that requires immediate corrective action, while Worker B had a score of 3, categorized as low risk. The most frequent complaints were concentrated in the lower back, shoulders, and wrists, primarily caused by repetitive bending and lifting movements from the conveyor to the pallet. The findings suggest that the main contributing factors are improper workstation height, repetitive tasks, and prolonged standing durations. Therefore, ergonomic improvements such as adjusting the height of the conveyor and worktable, implementing scheduled microbreaks, and providing posture training are recommended. These interventions are expected to reduce the risk of MSDs, improve worker comfort, and enhance overall productivity at the packing station.

The Caribbean region, despite its abundance of tropical agricultural commodities such as mangoes, continues to face challenges in product diversification and value-added processing. This community engagement program aimed to strengthen the productive capacity and economic empowerment of Caribbean communities—particularly small-scale farmers, agroindustry actors, and homemakers—through mango-based product development. Implemented by Politeknik ATI Padang in collaboration with the Non-Aligned Movement Center for South-South Technical Cooperation (NAM-CSSTC), the program was conducted virtually over two days in May 2025 using an integrated explicit–tacit knowledge transfer approach. Explicit knowledge was delivered through structured digital materials and video-based instruction, while tacit knowledge was reinforced through experiential learning, practical assignments, and interactive discussions. A total of 297 participants enrolled for the program, with 30 participants actively engaging through Zoom sessions and 267 participants accessing the training via YouTube livestreaming. The primary outcomes of the program included measurable improvements in participants’ technical competence, production readiness, and sustainability awareness. Evaluation results showed an increase in participants’ average scores from 84.4 (pre-test) to 89.2 (post-test), indicating enhanced understanding of mango jelly processing, packaging, waste utilization, and basic business planning. Moreover, participants successfully demonstrated their ability to independently produce mango jelly and apply organic waste management practices using mango peel residues. Beyond skill acquisition, the program fostered entrepreneurial motivation and promoted the adoption of circular economy principles at the community level. These findings highlight the effectiveness of virtual community empowerment initiatives in achieving tangible capacity-building outcomes and supporting sustainable, resource-based economic development across geographically dispersed regions.

Automation is increasingly applied in food-processing industries to enhance production efficiency. However, in onion-processing operations, peeling machines often fail to completely remove the outer skin, requiring workers to perform manual re-peeling to ensure raw-material quality. This task involves repetitive hand motions and forward-leaning postures, which may contribute to musculoskeletal strain. This study aims to evaluate the work posture of manual onion re-peeling workers using the Nordic Body Map (NBM) and Rapid Upper Limb Assessment (RULA) methods. Four workers participated in the study through direct observation, photo documentation, and questionnaire administration. NBM results indicated that the most frequent complaints occurred in the the shoulders, upper arms, elbows, forearms, wrists, and lower back. The average RULA score of 6 indicates a high-risk posture requiring prompt ergonomic intervention. The strong alignment between NBM and RULA findings reinforces the accuracy of the ergonomic diagnosis. This study highlights the need for ergonomic improvements such as workstation height adjustment, provision of lumbar-supported seating, micro-break scheduling, and simple tool redesign to reduce MSD risks and improve productivity in food-processing operations.

This study aims to identify inefficiencies in the tofu production process in small-scale tofu industries in Padang City, West Sumatra, and to propose improvements through an integrated work mapping approach. The analysis employs five types of work mapping tools, namely the operation process chart, flow process chart, layout flow diagram, man–machine chart, and right-hand–left-hand chart. The research method used is a qualitative case study conducted through direct observation, production cycle time measurements, and semi-structured interviews with the owner and workers. The results show that the total production cycle requires approximately 390 minutes, with the soaking stage (120 minutes) and molding stage (60 minutes) being the most time-consuming processes. The flow process chart identifies seven transportation activities with a total time of 16 minutes. Meanwhile, the man–machine chart reveals an imbalance in resource utilization, where the grinding machine operates for 33.1 minutes while the operator is active for only 3.1 minutes, resulting in 30 minutes of idle time. The right-hand–left-hand chart also indicates the dominance of right-hand movements in the cutting process, suggesting ergonomic inefficiency. The novelty of this study lies in the integration of five work mapping tools within a single analytical framework to provide a comprehensive evaluation of process flow, spatial layout, human–machine interaction, and manual motion patterns. The proposed improvements include workflow optimization, task redistribution, ergonomic workstation redesign, and the development of standard operating procedures (SOPs) to enhance efficiency and productivity in small-scale tofu industries.
