Abstract

The homemade snack food business is rapidly growing due to the high interest of the community in a variety of food options. Homemade food products are chosen because they are considered to have better quality and cleanliness. For example, sweet potatoes are processed into chips, and equipment such as sweet potato slicers and pots for frying sweet potatoes are crucial factors in determining the outcome of the chips. Initial observations with partners indicate difficulties in slicing and frying sweet potatoes due to limited equipment. Partners only have a double-edged knife for slicing sweet potatoes, resulting in unfulfilled customer orders. Emmi Snack Business faces challenges in meeting customer orders and requires innovation in attractive and secure packaging to ensure product quality.In this community service initiative, the main goal is to provide simple technological tools such as sweet potato slicers and fryers to increase production, as well as packaging equipment such as a vacuum sealer. This initiative also includes training on the use and maintenance of the equipment, as well as training on business management and simple bookkeeping. The results of this initiative will be published through scientific articles covering the service process and the achievements attained.

Abstract

Used cooking oil that is repeatedly used can be dangerous for health due to changes in composition and the release of acrolein, which can potentially cause cancer. This community service activity aims to raise awareness among the public about the dangers of consuming used cooking oil repeatedly. However, awareness of the dangers of cooking oil has created a new pollution problem related to waste disposal. People still dispose of used cooking oil directly into dishwashing sinks, drains, or even into the ground. The challenge faced by the Green Group partners so far is the fluctuation in the level of public interest and activity in collecting used cooking oil waste. Although the public has been educated about the impact of using used cooking oil waste and its indiscriminate disposal, the amount of oil collected is still not as expected. This challenge is being addressed by selecting one exemplary district, Datuk Bandar Sub-district, in Tanjungbalai City. Education is conducted collectively in village halls, door to door, and through the distribution of brochures and flyers. The public can submit used cooking oil waste to Green Group partners, which can be exchanged for money or basic necessities. The implementation team of the community service program is forming several community groups to extend the chain of public understanding about health and environmental preservation. The sub-districts in Datuk Bandar Sub-district become the pilot location that will later spread to other sub-districts, so that more people understand and participate in the activity. The hope is that the implementation of this community service program will achieve the third Sustainable Development Goals (SDGs), which is to ensure healthy lives and promote the well-being of people of all ages.

Abstract

A furniture company that produces dining chairs, coffee tables, and sofa has a common problem, namely the company's inability to complete production targets within the specified time period. These general problems are the result of less efficient production paths because there is backtracking, by-passing, cross movement, and material transfer between stations that are far apart. This problem can be resolved by using improvements to the production floor layout using BLOCPLAN, Systematic Layout Planning, and Algorithms Differential Evolution. This research aims to design a production floor layout that can minimize distance, total movement moment, and material handling costs, with a line efficiency rate above 75%. The results of this research show that the proposed layout was selected using the Differential Evolution Algorithm with a displacement distance of 231.24 meters, a total displacement moment of 15,820.93 meters/month, material handling costs of IDR 1,865,920/month, and a line efficiency rate of 81.94 %.

Abstract

Occupational health risks from chronic exposure to noise and airborne particulate matter remain a major concern in metal casting workplaces, especially in small-scale foundries with limited controls. The parameters measured in this study include noise exposure (Leq, dBA), particulate matter concentrations (PM₂.₅ and PM₁₀), and workers’ health symptoms. Field measurements at CV. Karya Yudita Baroqah showed exceedances of regulatory limits: noise levels in Molding and Finishing reached 89–93 dBA, and PM₂.₅ and PM₁₀ concentrations reached 72–80 µg/m³ and 155–174 µg/m³, surpassing recommended thresholds. These conditions indicate that workers are consistently exposed to hazardous environments that may lead to cumulative health impairments. This study aims to predict occupational health risk using a two-stage Random Forest model integrating environmental exposure data and workers’ symptoms. Stage-1 classified environmental risk levels with 99% accuracy, while Stage-2 predicted symptom-based health risk categories with 71% accuracy. PM₁₀ and PM₂.₅ were the strongest predictors, followed by noise intensity. The model demonstrates reliable performance and captures individual variability that traditional threshold-based assessments often overlook. The findings highlight that a combined machine-learning and HRA approach provides a practical, data-driven tool for early detection of high-risk workers and supports targeted interventions in metal casting workplaces.

Abstract

This literature review examines the application of methods such as Life Cycle Assessment (LCA), Design for Environment (DfE), Cradle to Cradle (C2C), Biomimicry, Circular Economy, and Sustainable Material Selection (SMS) in Sustainable Product Design & Development (SPDD). This study aims to synthesize existing research on the benefits, challenges, and integration of methods for environmentally sustainable product design through a narrative literature review of academic sources from 2008 to 2025, including textbooks and journals such as the Journal of Cleaner Production. The findings highlight that these methods collectively reduce environmental impacts by up to 70%, enhance resource efficiency, and foster innovation. However, challenges such as high implementation costs, data scarcity, and scalability issues persist. This review argues that an integrated framework combining LCA, DfE, and Circular Economy effectively mitigates these barriers by streamlining data requirements and optimizing long term cost efficiency through proactive design. Consequently, this integrated approach offers optimal outcomes for sustainable product development while supporting global regulations. Future research should prioritize empirical studies and interdisciplinary collaboration to further bridge the gap between theoretical frameworks and practical application.
