Abstract

  UMKM Banjar Biscuit "Bu Min" in Sumber Nongko Village, Jombang Regency produces traditional snacks made from sticky rice using manual methods, especially at the dough-pounding stage. This manual process causes physical fatigue in workers, affects production efficiency, and threatens product hygiene. With increasing market demand, UMKM faces major challenges in meeting consumer needs. To overcome this problem, an ergonomic dough-pounding tool was designed with dimensions of 140 cm high, 50 cm wide, 50 cm long, and a mortar diameter of 30 cm. This tool successfully reduced the Work Heart Rate (WHR) of workers from 118-149 to 93-124 beats/minute, indicating a significant reduction in cardiovascular load. In addition to increasing production efficiency, this tool maintains product hygiene and reduces the risk of worker injury. From a financial perspective, the cost of making the tool of Rp 5,306,000 has proven to be economical with an IRR of 5.26% per month (51.2% per year), a Profitability Index of 6.04, a positive NPV, and a Payback Period of only 2 months. This innovation helps MSMEs improve the quality and quantity of production while strengthening competitiveness in a competitive market. Keywords: Anthropometry, Cardiovascular Load, Engineering Economics

Abstract

PT. XYZ has problems in supplying large amounts of activated carbon to large companies; so far the company still relies on third-party expedition services to rent trailer trucks for its deliveries. To address this issue, we conducted an investment feasibility analysis using the capital budgeting method for truck procurement. The results of the analysis show that investment in the UD Quester GDE280 Euro 5 truck is feasible. The payback period (PP) was recorded at 3.91 months, the net present value (NPV) was Rp9,581,482,520, and the internal rate of return (IRR) reached 40.66%, far exceeding the minimum attractive rate of return (MARR) of 8.53%. The Profitability Index (PI) was also positive at 13.28%, and operational cost efficiency showed potential savings of 33.31%. Based on these indicators, the investment in truck procurement is not only financially feasible but also able to significantly increase the company's operational efficiency.

Abstract

Plastic seed products are products made from recycled plastic materials such as raw materials for plastic bags and some screen printing plastics. UD. ABC is a company that produces PP (Polypropylene) plastic pellets. The existing problems include the discovery of instability in the production of plastic pellets which is in a negative direction for the company, namely there are product defects in plastic pellet products that exceed the standard defect tolerance limit of the company by 2%. Based on the Pareto diagram, it can show that the type of protrusion defect is 69.56% more dominant than the type of connecting defect, which is 30.44%. Based on the control chart based on the p-chart, it shows that some dates are outside the limits of the control chart, namely the sample lot number 3 (March) of 0.0352, 4 (April) 0.0273, 7 (July) 0, 0134, 8 (August) 0.271. The data that comes out of the control chart limits exceeds the upper control limit (BKA/UCL) of 0.02649 and the lower control limit (BKB/LCL) of 0.02395. So what must be done to repair the engine factor is to carry out periodic briefings on how the machine works starting from setting the temperature and changing the filter. Meanwhile, the human factors section, namely directing the replacement of machine filter workers with temperature operators so that workers do not get tired easily, conducting periodic supervision of each worker for the leader and providing guidance on knowledge about machine work systems, mixing raw materials and operating machine temperature controls regularly.
