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.

Abstract

Furfural and levulinic acid are chemicals that can be produced from lignocellulosic biomass. In this research, mass balance simulation of furfural and levulinic acid production at scale of 100 tons of biomass/year was examined. This research using various models of kinetic reaction and biomass to solvent ratio from lignocellulosic biomass raw materials consisting of cellulose, hemicellulose, lignin, ash, and water composition of 35%, 30%, 25%, 3%, and 7%. The kinetic models used in this research were separate kinetic models and simultaneous model (model-3). The separate kinetic models were divided into two models which separate kinetic model 1 (model-1) and separate kinetic model 2 (model-2). SuperPro Designer 9.0 software was used to calculate mass balance simulation. From the research, it was found that variations in kinetic reaction model affected furfural and levulinic acid production. Higher biomass to solvent ratio produced higher furfural and levulinic acid production. The highest furfural produced from simulation process was kinetic reaction model-2 with a biomass to solvent ratio of 1:30 and 0.67 liter furfural/hour. While the highest levulinic acid produced from the simulation process was kinetic reaction model-1 with a biomass to solvent ratio of 1:30 and 2.37 liter levulinic acid/hour.

Abstract

Abstrak Limbah kertas dan nata de coco merupakan material yang mengandung selulosa. Selulosa yang terdapat pada limbah kertas dan nata de coco dapat dimanfaatkan untuk memproduksi produk dengan nilai jual tinggi yaitu karboksimetil selulosa (CMC). Pada penelitian ini diteliti produksi CMC dari limbah kertas dan nata de coco serta membandingkan nilai derajat subsitusi (DS) yang dihasilkan nya. Berdasarkan penelitian yang telah dilakukan diperoleh bahwa CMC dari nata de coco memiliki derajat subsitusi tertinggi yaitu 0,661 dengan konsentrasi NaOH dan natrium monokloroasetat (NaMCA) yang digunakan sebesar 20% dan 16 gram. Sedangkan CMC dari bahan baku limbah kertas memiliki derajat subsitusi terendah yaitu 0,066 dengan konsentrasi NaOH dan NaMCA yang digunakan sebesar 10% dan 10 gram. Konsentrasi NaOH dan NaMCA mempengaruhi nilai DS CMC, dimana semakin tinggi konsentrasi NaOH dan NaMCA yang digunakan akan menghasilkan nilai DS CMC yang tinggi. Pada penelitian ini diperoleh nilai DS CMC nata de coco lebih tinggi dibandingkan dengan DS CMC limbah kertas. Nilai DS pada CMC dapat diperoleh maksimal dengan adanya proses pretreatment bahan baku dan optimasi jumlah NaOH dan NaMCA pada proses produksi CMC. Abstract Paper waste and nata de coco contain cellulose. The cellulose which found in paper waste and nata de coco can be used to produce products with high selling value, namely carboxymethyl cellulose (CMC). In this research, CMC production from paper waste and nata de coco was examined and the value of degree of substitution (DS) produced was compared. Based on research that has been carried out, it was found that CMC from nata de coco had the highest DS, namely 0.661 with NaOH and sodium monochloroacetate (NaMCA) concentration used were 20% and 16 grams. Meanwhile, CMC from paper waste raw had the lowest DS, namely 0.066 with NaOH and NaMCA concentration used were 10% and 10 grams. The concentration of NaOH and NaMCA affects the DS CMC value, where higher NaOH and NaMCA concentration used will produce higher DS CMC value. In this study, the DS CMC of nata de coco was higher than the DS CMC of paper waste. The maximum DS value in CMC can be obtained by raw materials pretreatment and optimizing the amount of NaOH and NaMCA in the CMC production process.

Abstract

Clinker is the main ingredient in cement production which was produced by calcination process in a kiln with a burner. In this research, air requirements for the combustion process in burner to produce clinker were investigated. Based on the results, it was found that the air requirement for fuel combustion process was 127,403.849 (Nm3/hour). The combustion air requirement if 8% primary air used was 10,192.3 (Nm3/hour) and for 10% primary air used was 12,740.38 (Nm3/hour). The operational primary air flow (10.6%) was close to the theoretical primary air flow (10%), which operational primary air flow was 13,504.8 (Nm3/hour) and theoretical primary air flow (10%) was 12,740.38 (Nm3/hour).

Abstract

One of the most widely applied cellulose derivative products in industry is nitrocellulose which was produced through a nitration reaction between cellulose and nitric acid. In this research, the determination of the active intermediate reaction mechanism for nitrocellulose production was investigated. Four active intermediate mechanism models were used to predict the nitrocellulose formation reaction. Based on the results, it was found that models 3 and 4 which were active intermediate models that did not consider the effect of the sulfuric acid catalyst in the nitration reaction with irreversible nitration reaction. NO2+ ion was an active intermediate compound which had an important role in producing nitrocellulose. Sulfuric acid in the nitration reaction used to break down nitric acid into NO2+ ions without affecting the cellulose nitration process.

Abstract

Limbah kulit pisang dan limbah kulit pepaya merupakan limbah buah hasil konsumsi yang cukup banyak dihasilkan di Indonesia. Potensi kandungan mineral dan gula yang terdapat di dalam kedua limbah ini dapat digunakan sebagai media fermentasi untuk memproduksi biomaterial salah satunya adalah selulosa bakteri atau nata. Pada penelitian ini akan diteliti perbandingan produksi selulosa bakteri dari bahan baku limbah kulit pisang dan limbah kulit pepaya yang disertai pengaruh produksi selulosa bakteri terhadap penambahan etanol. Penelitian ini menunjukkan bahwa kulit pisang dan kulit pepaya dapat digunakan sebagai bahan baku dalam produksi selulosa bakteri dengan yield tertinggi sebesar 9,33% diperoleh dari media limbah kulit pepaya tanpa adanya penambahan etanol. Sedangkan yield terendah nata sebesar 1,33% diperoleh dari media fermentasi kulit pepaya dengan penambahan 3% etanol. Penambahan etanol pada penelitian ini menghambat proses fermentasi dikarenakan tingginya konsentrasi etanol yang digunakan. Etanol yang semula pada penelitian ini diharapkan sebagai sumber karbon berubah menjadi senyawa toksik bagi pertumbuhan Acetobacter xylinum.

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.
