Abstract

Indonesia has a lot of promising mineral wealth, one of which is copper, but its processing into cathodes is still minimal while domestic demand is not yet sufficient. In accordance with the strategic downstream investment plan for mineral commodities, especially copper, which has been included in the state downstream document, it requires a comprehensive financial feasibility document, especially for PT. X. The analysis in this research uses a reference capacity of 25,000 tons of cathode. This research aims to determine the technical factors in building a copper cathode factory, determine the amount of investment required in the form of CAPEX and OPEX, and determine its financial feasibility. The method used in financial feasibility analysis at PT. This X is Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PP). Based on the research results, it was found that the total CAPEX (Capital Expenditure) costs that had to be incurred were $ 330,589,628 and the total OPEX (Operational Expenditure) costs that had to be spent was $ 312,257,456 with an NPV value of $ 27,505,439, an IRR value of $ 27,505,439. 15.1%, and PP value for 6 years 10 months. Therefore, the project to build a copper cathode factory at PT. X is worth continuing.

Abstract

This study examines the implementation of Green Supply Chain Management (GSCM) in the Indonesian sports shoe industry and its impact on the company's competitive advantage. The objectives of the study were to analyze GSCM practices implemented by the Indonesian sports shoe industry, identify factors that influence the success of GSCM implementation, and measure its impact on the company's environmental performance and competitive advantage. The study used a quantitative approach with a survey method on 120 APRISINDO member sports shoe companies. Data analysis used Structural Equation Modeling (SEM) with AMOS software. The results showed that the implementation of GSCM including green purchasing, eco-design, green manufacturing, and reverse logistics had a significant positive effect on environmental performance (β=0.672, p<0.01) and competitive advantage (β=0.583, p<0.01). The main supporting factors for the success of GSCM were top management commitment, green technology capabilities, and collaboration with suppliers. This study provides theoretical and practical contributions to the development of GSCM in the Indonesian sports shoe industry.

Abstract

This study evaluates the technical and economic feasibility of constructing a 100 KL/day bioethanol production plant from sugarcane as part of Indonesia's national energy mix strategy. The research employs comprehensive analysis including mass balance, energy balance, technical design, and financial evaluation. The plant design utilizes fermentation and distillation processes with an annual production capacity of 36,500 KL bioethanol. Mass balance calculations show that 1,200 tons/day of sugarcane feedstock is required, producing 100 KL ethanol, 480 tons bagasse, and 120 tons vinasse daily. Energy balance analysis indicates the plant can achieve energy self-sufficiency through bagasse combustion for steam and electricity generation. Technical evaluation confirms the feasibility of implementing proven bioethanol production technology. Financial analysis reveals total investment requirement of USD 45.2 million with Net Present Value of USD 12.8 million, Internal Rate of Return of 18.5%, and payback period of 6.2 years at 12% discount rate. Sensitivity analysis demonstrates project robustness against feedstock price and ethanol selling price variations. The study concludes that the bioethanol plant is technically feasible and economically viable, contributing significantly to Indonesia's renewable energy targets and rural economic development while reducing dependency on fossil fuel imports

Abstract

Abstract: With the increasing demand for herbal medicine and efforts to reduce the import value of herbal drugs, PT Tugu Semar Production plans to enhance production by establishing a new factory. The planning utilizes the Systematic Layout Planning (SLP) method and conducts a financial feasibility analysis related to the investment. The prospective location is in Blitar, with a production capacity of 100 liters or 500 bottles. The research also encompasses a financial feasibility analysis using capex data of Rp. 4,539,800,000 and first-year opex of Rp. 3,646,980,053. The financial feasibility analysis results in an Internal Rate of Return (IRR) of 21%, indicating the financial viability of the investment. With a significant IRR, the project estimates a return on investment within 4 years and 8 months. These findings provide a comprehensive insight into the success of herbal medicine factory planning using the SLP method and instill confidence that this investment holds high financial feasibility potential. The implications of this research are expected to offer strategic guidance to PT Tugu Semar Production in decision-making concerning the development of the herbal medicine factory in Blitar.
