Abstrak

Pirolisis merupakan teknologi inovatif yang dapat mengubah berbagai jenis limbah menjadi produk yang bernilai tinggi. Minyak Pirolisis (MP) yang dihasilkan dapat digunakan sebagai bahan bakar alternatif. Penelitian ini bertujuan untuk mengetahui sifat fisik dan kimia MP ban bekas dan sampah plastik jenis HDPE dan PP yang selanjutnya dibandingkan dengan karakteristik bahan bakar komersial. Pirolisis dilakukan pada suhu 350 °C dalam waktu 4 jam. Hasil analisis menunjukkan sifat fisik MP HDPE C mirip dengan bensin dengan densitas 0,807 g/mL, viskositas dinamik 0,623 cP, dan viskositas kinematik 0,771 cSt. Tetapi, nilai kalornya masih sangat rendah dibandingkan dengan bensin. MP PP C memiliki nilai kalor hampir sebanding dengan bahan bakar komersial, yaitu sebesar 38,237 MJ/kg. Sedangkan pada MP Ban, sifat fisik dan nilai kalornya tidak memenuhi karakteristik bahan bakar. Analisis GC/MS menunjukkan Ban C1 memiliki kandungan senyawa olefin dan aromatik yang tinggi. Disisi lain, MP HDPE C memiliki kandungan senyawa parafin dan olefin yang tinggi, namun tidak mengandung senyawa aromatik. MP ban bekas dan sampah plastik berpotensi untuk digunakan sebagai bahan bakar. Kondisi pirolisis sangat mempengaruhi kualitas MP. Oleh karena itu, diperlukan optimalisasi kondisi pirolisis supaya dihasilkan MP dengan karakteristik yang mirip dengan bahan bakar.
