Kinerja Performansi Mesin Otto Menggunakan Campuran Bahan Bakar Bensin Bio dari Pyrolisis Sampah Plastik dengan Perbandingan Konsentrasi B10, B20, B30 dan B40

Abstract

This research identifies the performance of an otto engine that uses a mixture of plastic waste pyrolysis fuel, mixed with Pertalite in various ratios. The aim of this research is to evaluate the properties of this biofuel and their impact on engine performance, including torque, power, specific fuel consumption, thermal efficiency and exhaust emissions. The plastic waste used includes common types such as HDPE, LDPE, PET, and PP, and then mixed with Pertalite gasoline in the ratio B0 (100% Pertalite), B10 (10% Plastic Pyrolysis : 90% Pertalite), B20 (20% Plastic Pyrolysis : 80% Pertalite), B30 (30% Plastic Pyrolysis : 70% Pertalite), and B40 (40% Plastic Pyrolysis : 60% Pertalite). This research uses a Tiger 2880 generator engine for performance testing, focusing on various parameters such as heating value, density, viscosity and octane number. Research methods include collecting plastic waste to be processed, making plastic oil through a pyrolysis process, refining plastic oil into gasoline, and performance testing on otto engines. The results show that the biofuel mixture from pyrolysis of plastic waste with pertalite can function as an alternative fuel, and has the potential to reduce the accumulation of plastic waste as well as dependence on fossil fuels. This research contributes to developing sustainable fuel alternatives and highlights the feasibility of recycling plastic waste into a valuable resource.
