Abstract
Burdened by oil imports and subsidies for more than 5000 diesel power plants, Indonesia aims to use crude palm oil (CPO) as fuel in the power plants. Previous studies only focused on the technical feasibility of using CPO. Therefore, this study aimed to enrich the existing literature by analyzing the technical feasibility of using CPO, degummed CPO, and bleached palm oil (BPO) fuels on endurance test for 500 operational hours with a 20 kW diesel engine capacity for each type of fuels. Our analysis included component rating and the measurement of specific fuel consumption, emissions, oil dilution, and deposit materials. The assessment concluded that diesel engines using CPO, BPO, and degummed CPO increased specific fuel consumption, deposit formation, and emissions of carbon monoxide and carbon dioxide compared to engines using a 30% FAME blend in HSD or Biodiesel 30. This implies that CPO, BPO, and degummed CPO could be used in diesel engines, though fuel consumption and maintenance costs tend to increase. Based on the test results, we provided an efficient CPO supply chain from CPO mills to diesel power plants.
