Increasing the need for fuel oil is something that can’t be avoided, while the supply of fossil fuels is running low. Biodiesel is one of the right solutions to overcome this problem. This vast ocean in Indonesia, makes Indonesia the potential to create biodiesel from fish canning industry waste. The purpose of this research is to analyze the effect of dexlite fuel mixture with biodiesel from fish canning industry waste on fuel consumption and exhaust gas opacity in agriculture diesel engines. This type of research uses experimental research. The object of this research is the exhaust emissions and fuel consumption. The results of the study obtained by the researchers are the results of mixing dexlite of Pertamina (gasoil/high speed diesel oil) fuel with biodiesel of fish waste oil to be used in diesel engines. The highest exhaust gas opacity results in a mixture of 70% dexlite with 30% biodiesel (B30) of 2.6% at 1000 RPM (± 5). The results of the test fuel consumption that most quickly runs out occur in pure dexlite for 131 seconds in 10 ml of fuel at 1000 RPM (± 5). The results of testing the exhaust gas opacity level are increasing, as well as the results of testing fuel consumption which is increasingly economical, due to the high water, carbon and ash content in biodiesel.
