Abstract

The utilization of water hyacinth (Eichhornia crassipes) as a raw material for woven handicrafts has become an environmentally friendly economic activity in several rural communities in Indonesia. However, one of the persistent challenges in the production process lies in the preparation of the wire frame, which functions as the main structural support for shaping the product. Manually straightening wire is labor-intensive, inconsistent, and ergonomically harmful, especially for women artisans. This community service initiative aimed to improve the quality and efficiency of water hyacinth woven products through the introduction of an appropriate technology innovation: a manually operated wire straightener machine. The design was developed based on participatory ergonomics principles and tested in a home-based handicraft production setting in Banyumas, Central Java. The implementation involved tool handover, training, and evaluation of its impact on product quality and work comfort. Results showed a significant improvement in wire straightness, reduced physical fatigue among artisans, and better structural consistency of the final products. The findings demonstrate that simple ergonomic innovations can effectively enhance artisanal productivity and occupational well-being. This initiative has the potential to be replicated in other craft-based communities to support sustainable microenterprise development.

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.
