Abstract

In new product development, the selection of production machines is one very important part because it will greatly affect the success of product development. PT X is a company engaged in the packaging manufacturing industry. Currently PT X is developing biodegradable packaging products that meet food grade standards. In this project's case study, there are four engine brands that will be considered for selection. This study aims to determine priority criteria and the best alternative Pulp Molding machine. This study integrates the AHP method with TOPSIS. The AHP method is used to weight assessment criteria supported by the use of Super Decisions software, while the TOPSIS method is applied to sort the ranking of alternative machines. This study succeeded in determining the most important criteria in determining the choice of engine, in this case the production capacity with a weight of 0.395, while the best alternative machine to choose is JKE with a preference value of 0,503. Thus, this research can contribute to PT X in determining the choice of Pulp Molding machine.

Abstract

Background: This community service program was implemented to address musculoskeletal complaints among production workers who frequently adopted squatting postures, which imposed static loads on the lower back, knees, and calves, resulting in discomfort and reduced productivity. Contribution: This study introduces ErJo (Ergonomic Jojodog), a culturally adaptive ergonomic innovation that integrates traditional sitting design with modern ergonomic principles to enhance worker comfort and foster cultural acceptance. Method: A participatory ergonomics approach involving ten production workers was employed through design, testing, and evaluation stages. Musculoskeletal complaints were assessed using the Indonesian National Standard (SNI 9011:2021), complemented by field observations and semi-structured interviews. Results: After two weeks of ErJo implementation, musculoskeletal complaints in the knees and calves decreased from 67% to 20%, while lower-back discomfort declined to 40%. Participants reported greater comfort, stability, and ease of movement, with the belt-equipped model achieving the highest usability score. This study demonstrates that integrating ergonomics with local wisdom enhances worker well-being and promotes sustainable occupational practices. Conclusion: ErJo effectively reduced musculoskeletal complaints and improved work comfort in squatting tasks. This innovation supports SDG 3 (good health and well-being) and SDG 8 (decent work and economic growth), with potential for broader application across similar manual occupations.
