Abstract

We used a few financial ratios in this study: the price-earning ratio (PER), net profit margin (NPM), debt-to-equity ratio (DER), current ratio (CR), and economic ratio (ER). Our goal is to gather actual data regarding changes in the financial performance of nickel companies listed on the BEI before and after the implementation of Permen No. 11 in 2019 regarding the export restrictions of nickel ore. This is a quantitative study that uses SPSS and the Paired T-test method. The financial accounts of nickel companies serve as a secondary data source for our investigation.

Abstract

The increasing demand for sustainable energy solutions in rural areas has prompted the utilization of biogas and bio-slurry as alternative resources. This study aims to evaluate the economic feasibility of household-level biogas systems by integrating Cost-Benefit Analysis (CBA), Net Present Value (NPV), Benefit-Cost Ratio (BCR), and Undiscounted Payback Period (UPBP), complemented with sensitivity analysis. Primary data were collected from 16 households operating biogas systems, while secondary data supported the estimation of cost and benefit components. Results show that biogas adoption provides positive economic returns, with average NPV reaching Rp 12,749,000, BCR above 1.0, and UPBP within four years, indicating financial viability. Sensitivity analysis reveals that variations in LPG prices and livestock numbers significantly affect economic outcomes, demonstrating the importance of market and production factors in ensuring project sustainability. The findings conclude that household biogas systems are economically feasible and resilient under certain conditions. Future studies are suggested to expand the scope by incorporating environmental and social benefits,a s well as exploring scalability at the community level.
