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.

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.
