Abstract

Bioethanol is ethanol produced from glucose (sugar) fermentation, followed by the distillation process. Another method besides distillation is needed to increase the bioethanol produced. This study aims to increase the levels of bioethanol from pineapple skin using a cracking former catalyst by comparing the effectiveness of the use of chemically activated adsorbents using a base (NaOH) and acid (HCl). The adsorbent used in this study is the former RU III cracking catalyst, the FCC catalyst. The adsorbent is as a substitute for natural zeolite adsorbents, which are relatively expensive compared to the FCC catalyst. The results showed that the most effective ratio for bioethanol levels was 10 mL: 6 gr of adsorbent that activated by HCl, was 63.73%.

Abstract

Waste from sugar cane, bagasse or bagasse contains cellulose which is the main raw material for making pulp. The lack of utilization of sugarcane bagasse makes sugarcane bagasse into a pile of garbage that pollutes the environment. This research aims to make pulp from sugarcane bagasse using NaOH as a cooking solution and H2O2. The research method was carried out by varying the cooking solution at 2%, 4%, 5%, 6%, 8%, and 10% NaOH concentrations at temperatures of 100oC, 110oC, 120oC, 130oC and 140oC, then proceed with calculating the percentage of yield and permanganate numbers . The highest percentage of yield is at a temperature of 140oC with a concentration of 2% NaOH, while the lowest permanganate number is at a temperature of 140oC with a concentration of 10% NaOH.
