Abstract

Penelitian ini bertujuan untuk mengetahui perbandingan rendemen minyak yang diperoleh dari limbah plastik HDPE dengan membandingkan bahan bakar minyak yang dihasilkan secara kuantitatif dan kualitatif. Pengolahan sampah plastik menggunakan proses pirolisis dilakukan dengan volume pelarut yang bervariasi (20%; 40%; 60%; 80%; 100%) yang dilakukan pirolisis selama 2 jam. Dalam suatu percobaan diperlukan 500 gram sampah plastik, 250 gram katalis dolomit dan % ml pelarut H2SO4 sesuai variasi. Penelitian ini dilaksanakan di Laboratorium SKL Jurusan Teknik Universitas Jambi dengan parameter yang diuji meliputi analisis volume, massa, %-yield, densitas dan GC-MS. Hasil penelitian menunjukkan bahwa secara kuantitatif volume, massa dan % rendemen terendah terdapat pada variasi volume 20%, dan tertinggi pada variasi volume 100%. Hasil pengujian sampel produk CHP pada variasi pelarut 100% menggunakan instrumen GC-MS menunjukkan bahan bakar jenis bensin dengan rantai karbon C5-C12 sebesar 79,72% dan senyawa aromatik yang terkandung didalamnya sebesar 12,62%. Bahan bakar yang dihasilkan sesuai standar SNI 3506-2017 dengan jenis bensin RN 88 yang mempunyai massa jenis 0,7600 gram/ml.

Abstract

Palm oil shells are solid waste from the palm oil processing industry. In 1 ton of palm oil produces 6.5% shell waste. Solid waste can be converted into fuel as a substitute for oil, namely bio-briquettes as an alternative fuel through a combustion process with less air. This study aims to determine the effect of time variations on the quality and yield of bio-briquettes produced using a combined pretreatment method of densification (with additional binder) and torrefaction at a temperature of 275 oC and time variations of 30, 45, 60, 75 and 90 minutes. Torrefaction is a new method in the briquetting process where this method takes place at low temperatures. The results showed that the longer the torrefaction time, in general, the value of water content, ash content, volatile matter content, fixed carbon value and burning time also increased. However, this is inversely proportional to the yield value of the resulting product, so the best quality is obtained in 75 minutes with a moisture content of 0.86%, ash content 2.38%, volatile matter content 18.23%, fixed carbon value 78.51 %, product yield is 36.3165% and calorific value is 5964 Kcal/kg.
