Abstract

Abstrak- Desa ranggang merupakan sentra produksi arang kayu di Kalimantan Selatan. Arang kayu diproduksi dalam tungku dari tanah liat berbentuk kubah dengan diameter sekitar 4 meter dan tinggi 3-4 meter. Di Desa Ranggang ini terdapat lebih dari 500 buah tungku dengan kapasitas produksi arang kayu sekitar 2-3 ton arang/tungku untuk tiap kali produksi. Asap yang keluar dari tungku arang pada proses produksi arang jumlahnya sangat besar selama ini terlepas ke lingkungan yang berpotensi menimbulkan polusi udara dan mengganggu pengrajin arang tersebut.. Penelitian tentang potensi asap cair sebagai produk samping pembuatan arang kayu desa ranggang tersebut dilakukan dengan memodifikasi model tungku arang desa Ranggang berupa penambahan instalasi kondensasi asap pada bagian knalpot tungku. Tungku arang percontohan telah dibuat dengan kapasitas produksi 3 ton arang setiap kali produksi. Bahan baku yang digunakan adalah limbah kayu ulin (Eusideroxylon zwageri Teijsm. & Binn.). Asap cair yang diperoleh dari tungku tersebut sejumlah 47 liter untuk setiap kali produksi. Asap cair yang dihasilkan didominasi fraksi suhu 95-105 0C, yaitu sebanyak 81%, memiliki kadar  asam (dihitung sebagai asam asetat) 0,825 molar dengan pH berkisar. 2,91-3,08. Kata kunci: asap cair, produk samping, produksi arang, kondensasi asap dan tungku arang Ranggang

Abstract

Abstract - Research on the effect of the use of HCl concentrations in the hydrolysis process of cellulose from medang wood (Neolitsea latifolia) on the characteristics of microcrystalline cellulose has been studied. The purpose of this study was to determine the effect of HCl concentration on the characteristics of microcrystalline cellulose. The analysis carried out included yield, pH, color, functional group characterization using FTIR and crystallinity index using XRD. The hydrolysis process was carried out at 105 °C for 15 minutes with variations in HCl concentrations of 1.5 N, 2.5 N and 3.5 N. Based on the results of the research conducted, the results showed that the use of variations in the concentration of HCl in the hydrolysis process affected the yield, color, TCI (Total Crystallinity Index) value of FTIR data and crystallinity index of XRD data. The yield of microcrystalline cellulose produced from each variation of concentration was 64.41, 61.94 and 53.99. The color of microcrystalline cellulose is getting darker as the concentration of HCl is used. Based on FTIR data, the TCl value of microcrystalline cellulose from each variation of concentration was 0.861%, 0.907% and 0.976%. XRD data shows an increase in crystallinity index produced from each variation in concentration on microcrystalline cellulose amounted to 80.52%, 82.17% and 83.49%.
