Today the fuel used for broad commercial flights is Jet A-1. Problems arise because fossil fuels are primary energy with non-renewable resources which are the largest energy consumption in the world. Indonesia has the potential to develop bioavtur made from biomass as Indonesia is one of the largest coconut producing countries in the world. This research aims to analyze and compare the values of performance parameters, such as compressor outlet temperature, turbine inlet temperature, turbine outlet temperature, fuel flow, air flow, specific fuel consumption (SFC), thermal efficiency, AFR, and combustion efficiency also exhaust emissions parameters, like CO, CO2, NOx, HC, smoke, and O2 in gas turbines using jet biofuel mixtures of 0%, 2%, and 10%. Jet Biofuel is produced through the Hydro-Processed Esters and Fatty Acid (HEFA) process. Tests are carried out on the Rover 1s/60 Gas Turbine. The performance results for mixture of jet biofuel concentrations of 2% and 10% in compressor outlet temperature, turbine inlet temperature, turbine exhaust temperature, fuel mass rate, air mass rate, SFC, AFR, and thermal efficiency have a percentage difference of 0,01%–1,64% to the performance of Jet A-1. In combustion efficiency, the percentage difference in the mixture of jet biofuel concentrations 10% is 2.13% higher than Jet A-1. Meanwhile, in the jet biofuel mixture the concentration of 2% is 0.90% higher than Jet A1.While the results of exhaust emissions for CO, NOx, HC, smoke opacity, and oxygen show that the Jet A-1 occupies the highest position followed by mixture of jet biofuel concentrations 2% and 10%. However, on CO2 emissions, the mixture of jet biofuel concentrations 10% produces the highest CO2 followed by mixture of jet biofuel concentrations 2% and Jet A-1.
