Studi Eksperimental Co-Pyrolysis Biomassa Dan Sampah Plastik Jenis Low Density Polyethylene (Ldpe) Sebagai Bahan Bakar Alternatif

---

ABSTRACT
Co-pyrolysis offers a promising approach to reducing Indonesia’s dependence on fossil fuels, which has led to serious environmental problems such as greenhouse gas emissions and air pollution. This study aims to evaluate the effects of temperature variation and blending ratios in the co-pyrolysis of oil palm empty fruit bunches (OPEFB) and low-density polyethylene (LDPE) on bio-oil yield, physicochemical properties, calorific value, and chemical composition. The experiments were conducted in a fixed-bed reactor at temperatures ranging from 400 to 600°C with OPEFB:LDPE ratios from 100:0 to 0:100. The results indicate that the temperature for maximum bio-oil yield (37.40%) was 550°C. A 50:50 blending ratio produced the highest liquid yield, while a 25:75 ratio provided the best balance between high-quality bio-oil and energy-rich bio-char. Increasing LDPE proportion decreased the density and viscosity of bio-oil but significantly enhanced its calorific value, reaching the highest value in pure LDPE pyrolysis. GC-MS analysis revealed a notable increase in hydrocarbon fractions and a reduction in oxygenated and N/S compounds with higher LDPE content. Overall, the co-pyrolysis of OPEFB and LDPE effectively improves the physical and chemical quality of bio-oil while simultaneously providing an integrated solution for biomass and plastic waste management, supporting the transition toward cleaner and more sustainable energy.
