Waste generated from community life activities continues to increase along with economic development and population growth. Systematic, comprehensive, and sustainable waste management is needed to overcome problems related to waste generation, both through efforts to reduce and handle waste. One waste management innovation is using fuel waste, called Refuse Derived Fuel (RDF). Utilization of RDF can process waste on a large scale and can be a substitute for fossil fuels for industry, one of which is the cement industry. This research analyzes the financial feasibility of processing waste into RDF for cement factories. The case study was carried out at a landfill in Ogan Komering Ulu Regency - South Sumatra Province, with PT Semen Baturaja Tbk as offtaker of RDF. Financial feasibility analysis uses Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP), and Profitability Index (PI) indicators. A sensitivity analysis of financial feasibility was carried out on changes in RDF selling prices and operational costs. This analysis of the scenario 1 (70% equity : 30% debt) and the scenario 2 (30% equity : 70% debt) shows that the Project of RDF Plant is feasible to implement. Sensitivity analysis of scenario 1 and 2 are not feasible at 20% decrease in selling price and scenario 2 is not feasible at 20% increase in investment. [ABSTRACT FROM AUTHOR]

This research was conducted to analyze the impact of construction costs and traffic volume as the main parameters to the feasibility of an investment project with a case study on part of the road of the Sumatran toll road network, located on the Island of Sumatera, which is one of the largest islands in Indonesia. Financial analysis uses indicators of Net Present Value (NPV), Internal rate of return (IRR) and Benefit Cost Ratio (BCR). Investment costs are based on current actual conditions, while revenue is derived from the realization of traffic volume crossing the toll roads. The results of the analysis show that due to the high increase in investment costs accompanied by a decrease in income due to the large difference in traffic volume projections, the project that was originally feasible change to financially not feasible. Therefore, further efforts possible are needed to make the investment feasible. The results show that the required increasing toll tariffs is 1.996 times higher than the initial one, while the extension of the concession does not show any improvement in financial feasibility. Therefore, a proposal is needed so that the tariff is according to the ability and ability of road users while maximizing the potential for non-tariff income. [ABSTRACT FROM AUTHOR]
