Abstract

Due to increasing fuel prices, most people in Indonesia choose to use fuel with an octane rating of 90. However, using fuel with a lower Research Octane Rating or RON can affect the performance and efficiency of vehicle engines, especially if the compatibility between fuel octane and the engine's compression ratio is neglected. One solution to this problem is adding an octane booster to RON-90 gasoline to resemble gasoline with an octane rating of 92. The purpose of this research is to conduct an experimental study to see the effect of using a commercially available octane booster on the fuel consumption of a multi-purpose vehicle with an engine capacity of 1500 cc. Fuel consumption testing was performed using a road test based on the full-to-full method. The measurement results show that using an octane booster in RON -90 gasoline can reduce vehicle fuel consumption by 6.82%. However, the decrease in fuel consumption is still less compared to vehicles using RON-92 gasoline. Economic analysis found that using an octane booster in a motorcar could be a cost-efficient alternative to a more expensive RON-92 petrol.

Abstract

The insulator system in substations is essential in maintaining safety and efficiency in electricity transmission and distribution lines. The purpose of this research is to conduct High Voltage tests to check possible malfunctions in a gas-insulated switchgear (GIS) in a 150 kV substation following IEC standard 62271-203. Insulation Resistance (IR) measurement results for components in the GIS system show that the system still has high insulation resistance for the R, S, and T phases. High voltage testing results for the three-phase Gas Insulated Switchgear also did not exhibit current leakage, meaning the system still operates satisfactorily.
