Abstract

Small and medium enterprises in flour processing still rely heavily on manual drying processes, which pose high risks of musculoskeletal disorders and low productivity. This community service program aimed to implement an ergonomically designed spreading and leveling machine to improve working posture and production performance at Kusuka Ubiku SME in Bantul Regency. The program was conducted through problem identification, assessment of workers’ physical complaints using the Nordic Body Map, posture risk analysis using Rapid Entire Body Assessment, ergonomic machine design based on anthropometric data through the Need–Idea–Decision–Action approach, followed by on-site implementation and mentoring. The results show a significant reduction in posture risk from a high-risk category to a low-risk category and an increase in worker productivity by 53.6 percent. These findings demonstrate that the application of ergonomics-based appropriate technology effectively enhances occupational health and operational efficiency in food-processing SMEs.

Abstract

This study develops an optimization model to enhance the distribution efficiency of a frozen food distributor. The company faces operational inefficiencies due to excessive fleet capacity and conventional route assignment methods, which increase travel distances and overall distribution costs. To address these challenges, an extended Capacitated Vehicle Routing Problem with Time Windows (CVRPTW) model is proposed, which integrates heterogeneous fleet characteristics and prioritizes customer service constraints. The model is solved using the Large Neighborhood Search (LNS) metaheuristic to determine optimal routing and fleet allocation strategies. The optimized model achieves a 15.95% reduction in total travel distance and a 21.84% decrease in total distribution costs compared with the company’s current operations. The findings confirm the effectiveness of the LNS-based CVRPTW approach in improving logistics performance and provide practical insights for companies seeking to minimize distribution costs through strategic route planning and fleet management.
