Abstract

The problem of increasing waste generation in Indonesia, particularly in Karawang Regency, poses a serious environmental threat if not properly managed. One sustainable alternative is to utilize paper and cardboard waste as raw materials for eco-briquettes. This study aims to develop eco-briquette products and design a production machine capable of improving the efficiency of non-hazardous waste processing. The research method applied was experimental and engineering design. The experiment was conducted by producing several briquette samples with different compositions of paper, cardboard, and tapioca starch, which were then tested through burn duration and physical performance evaluation. The results showed that briquettes with a composition of 80% cardboard and 20% tapioca starch performed best, with a burn time of 21 minutes. Furthermore, a production system design was proposed, consisting of cutting, mixing, pressing, crushing, second mixing, and molding machines, with a production target of 100 briquettes per day. This design is projected to reduce paper and cardboard waste by approximately 1.197 tons per month. Therefore, this study demonstrates that utilizing non-hazardous waste for eco-briquette production not only provides a solution for waste reduction but also supports economic value and environmental sustainability. Keywords: Briquette, Design, Experiment, Paper, Waste

Abstract

This study aims to analyze the maintenance system of production machines at PT. ABC, a company engaged in die casting molds, plastic injection molds, precision parts, and jig fixtures. Based on failure frequency data from 2023–2025, Lathe Machine 1 was identified as the machine with the highest breakdown rate, with the dynamo component being the most critical part. To determine the optimal maintenance strategy, a reliability analysis was conducted using a lognormal distribution. The results showed that the Mean Time To Failure (MTTF) of the dynamo reached 287.87 hours, while the Mean Time To Repair (MTTR) was recorded at 3.34 hours. Based on these calculations, the optimal replacement interval was determined to be 154 hours, or approximately ±21 days, with an availability level of 0.9929 and a reliability level of 0.7617. From an economic perspective, the preventive maintenance method proved to be more cost-effective compared to corrective maintenance, offering potential cost savings of up to 61.86%. These findings highlight that the implementation of preventive maintenance not only reduces maintenance costs but is also effective in minimizing machine downtime, improving operational reliability, and ensuring smooth production processes. Therefore, preventive maintenance is strongly recommended as a key strategy to enhance operational efficiency and production sustainability at PT. ABC, while also serving as a valuable reference for future decision-making in the maintenance of critical machine components. Keywords: Age Replacement, Maintenance Cost, MTTF, MTTR
