Abstract

Limbah kulit pisang dengan kandungan yang kaya akan nutrisi dan mineral memiliki potensi untuk dibuat selulosa bakteri. Pada penelitian ini akan diteliti kinetika reaksi pembuatan selulosa bakteri dari limbah kulit pisang. Model kinetika yang digunakan pada penelitian ini menggunakan metode kinetika fermentasi. Berdasarkan hasil penelitian yang telah dilakukan diketahui bahwa produksi selulosa bakteri berada pada tahap eksponensial dengan lama waktu fermentasi selama 14 hari. Waktu fermentasi mempengaruhi selulosa bakteri yang dihasilkan dimana semakin lama waktu fermentasi yang digunakan akan menghasilkan semakin besar massa selulosa bakteri. Kulit pisang sebagai bahan baku pada penelitian ini dapat memenuhi kebutuhan karbon untuk fermentasi selain glukosa. Parameter kinetika produksi selulosa bakteri dari limbah kulit pisang sesuai hasil optimasi antara data dan model kinetika diperoleh nilai parameter kinetika reaksi yaitu µmax (maximum specific growth rate), ks (konstanta monod), kd (konstanta laju kematian sel) dan m (konstanta sel maintanance). sebesar 0,297/hari, 2,059 g/L, 1,137/hari dan 1,325/hari.

Abstract

The need for paper results in a lot of paper waste. Paper waste, which is lignocellulosic, can be hydrolyzed using an acid catalyst to produce various cellulose degradation products. In this study, the effect of the sulfuric acid catalyst addition method on the waste paper hydrolysis process was investigated. The addition of the catalyst was carried out in three types. The Type-1 method was sulfuric acid addition in the 0th minute. The Type-2 method was sulfuric acid addition in the 0th and 30th minutes. The Type-3 method was sulfuric acid addition every 10 minutes. The results showed that the lowest residual mass of waste paper hydrolyzed was produced using the Type-3 method. This showed that the Type-3 method, sulfuric acid addition every 10 minutes, had an effect on the residual mass of the hydrolyzed sample. The Type-3 method was the most effective type of sulfuric acid catalyst addition compared to other types. On the other hand, variations in the concentration of the sulfuric acid catalyst affect the residual mass of the waste paper hydrolyzed sample, where higher sulfuric acid concentration will lower residual mass. The catalyst concentration of 2% sulfuric acid with The Type-3 addition method resulted in the highest conversion which was 38.27%.

Abstract

The hydrolysis reaction is a rupture reaction of reactants with water which is generally used to produce useful derivative products and can be reviewed for kinetics as a basis for reactor design. Nata or bacterial cellulose is a compound consisting of pure cellulose and water so that it can be hydrolyzed to produce various cellulose degradation products. This research examined the kinetic hydrolysis of bacterial cellulose using a sodium hydroxide catalyst. This study aimed to determine the kinetic parameters of the nata hydrolysis reaction using a base sodium hydroxide catalyst. The results showed higher temperatures and longer hydrolysis time performed better in hydrolysis reactions. The hydrolysis kinetics in this study were divided into two types, Type 1 hydrolysis kinetics which used the wet weight of bacterial cellulose, and Type 2, which used the dry weight of bacterial cellulose. From the calculation results, the order of bacterial cellulose hydrolysis reaction ranges from 5 – 6, with the kinetic constants of Type 1 hydrolysis kinetics at 40oC, 60oC, and 80oC were 0.000012, 40,255.4, and 299,839 min-1. In comparison, the reaction constants of Type 2 hydrolysis kinetics at 40oC, 60oC, and 80oC were 0.516851, 1.124119, and 2.408972 min-1. The activation energy of Type 1 hydrolysis kinetics was 558.3932 kJ/mol, and Type 2 hydrolysis kinetics was 35.31205 kJ/mol. The difference in kinetic parameter values for Types 1 and 2 will be a reference in designing a nata hydrolysis reactor from wet and dry nata reactants to produce various cellulose degradation compounds.ABSTRAKReaksi hidrolisis merupakan reaksi pemecahan reaktan dengan air yang umumnya dilakukan untuk memproduksi produk – produk turunan bermanfaat dan dapat ditinjau kinetikanya sebagai dasar dalam perancangan reaktor. Nata atau selulosa bakteri merupakan senyawa yang terdiri dari selulosa murni dan air sehingga dapat dihidrolisis untuk menghasilkan berbagai senyawa degradasi selulosa. Pada penelitian ini diteliti kinetika hidrolisis selulosa bakteri menggunakan katalis natrium hidroksida. Tujuan dari penelitian ini adalah untuk menentukan parameter kinetika reaksi hidrolisis nata menggunakan katalis basa natrium hidroksida. Hasil penelitian menunjukkan bahwa semakin tinggi suhu dan lama waktu hidrolisis akan meningkatkan kinerja reaksi hidrolisis. Kinetika hidrolisis pada penelitian ini terbagi dua tipe yaitu kinetika hidrolisis Tipe 1 yang menggunakan berat basah selulosa bakteri dan dan Tipe 2 yang menggunakan berat kering selulosa bakteri. Dari hasil perhitungan diperoleh orde reaksi hidrolisis selulosa bakteri berkisar antar 5 – 6 dengan konstanta reaksi kinetika hidrolisis Tipe 1 pada suhu 40oC, 60oC dan 80oC berturut – turut adalah 0,000012; 40.255,4; dan 299.839 min-1. Sedangkan konstanta reaksi kinetika hidrolisis Tipe 2 pada suhu 40oC, 60oC dan 80oC berturut – turut adalah 0,516851; 1,124119; dan 2,408972 min-1. Energi aktivasi kinetika hidrolisis Tipe 1 sebesar 558,3932 kJ/mol, dan energi aktivasi kinetika hidrolsis Tipe 2 sebesar 35,31205 kJ/mol. Perbedaan nilai parameter kinetika pada Tipe 1 dan 2 akan menjadi acuan dalam perancangan reaktor hidrolisis nata berbahan baku nata basah dan kering untuk memproduksi berbagai senyawa degradasi selulosa.

Abstract

Paper waste can cause environmental damage, so paper waste processing must be carried out. Paper waste which is a lignocellulosic compound can be processed with acid hydrolysis process to produce cellulose degradation products. In this research, waste paper hydrolysis was carried out using sulfuric acid with response surface methodology (RSM) optimization which the variables studied were mixing speed, time and S/L ratio. Based on the results of ANOVA test, it was known that mixing speed, time and solid liquid (S/L) ratio did not have a significant influence on %conversion. From the comparison of the independent variables, the mixing speed and time showed significantly influence %conversion compared to the S/L ratio. Higher %conversion was obtained from lower value of mixing speed, time and S/L ratio. In this study, 65% conversion was produced under operating conditions of 175 rpm stirring speed, 30 minutes reaction time, and 1:15 S/L ratio.
