Abstract

This research aims to utilize the Arabica coffee cascara waste as a resource for reducing sugar production, including the investigation on the temperature and time required of the acid hydrolysis. The samples were initially pretreated (drying and milling), followed by delignification with the organosolv technique using alcohol. Then, the hydrolysis was carried out using sulfuric acid (1%) at a particular temperature (95, 100, and 105 °C) and time (2, 4, and 6 h) variations. Yield percentage, density, and reducing concentration were analyzed in each trial to generate a response surface methodology model. Based on the results, the hydrolysis can be optimized at 96.46 °C for 2.59 h, yielding 16.7696% reducing sugar.

Abstract

Rice straw is a waste from rice plants that contains 37.71% cellulose, 21.99% hemicellulose, and 16.62% lignin. High cellulose content in rice straw can be used as raw material for the manufacture of Carboxymethyl Cellulose (CMC). CMC is a cellulose derivative widely used in food, pharmaceutical, detergent, textile and cosmetic products industries as a thickener, stabilizer of emulsions, or suspensions and bonding. This study aims to process rice straw waste into CMC with variations in sodium monochloroacetate of 5,6,7,8 and 9 grams. The method used in this research is by synthesis using 15% NaOH solvent, with a reaction time of 3.5 hours and 5 grams of rice straw. The results showed that the best CMC was obtained at a concentration of 9 grams of sodium monochloroacete with a yield characterization of 94%, pH 6, water content of 13.39%, degree of substitution (Ds) of 0.80, and viscosity of 1.265 cP.

Abstract

Salah satu pencemar yang berbahaya dalam limbah buangan industri yaitu logam berat besi (Fe2+). Banyak teknik pengolahan yang dilakukan untuk mwnurunkan kadar logam berat besi. Salah satunya diantaranya adalah dengan teknik adsorbs.  Adsorpsi sering digunakan karena prosesnya yang sederhana dan efektif untuk mengurangi kadar logam berat. Penelitian ini bertujuan untuk menganalisis efektifitas karbon aktif kulit singkong sebagai adsorben pada penyerapan logam besi (Fe2+), mengkaji pengaruh waktu kontak dan variasi konsentrasi aktivator terhadap daya serap besi (Fe2+) serta mekanisme penyerapan melalui metode pendekatan isotherm adsorpsi Freundlich dan Langmuir. Penelitian ini dilakukan dengan suhu karbonasi 300 ºC selama 2 jam dengan variasi konsentrasi aktivator 10%, 20%, 25%, dan 30% serta memvariasikan waktu kontak selama 30, 60, 90, dan 120 menit. Hasil yang diperoleh adalah, % efisiensi adsorpsi maksimum yaitu 94,07% serta kapasitas adsorpsi maksimum yaitu 470,35 mg/g pada konsentrasi aktivator 30% dan waktu kontak 120 menit. Mekanisme adsorpsi yang terjadi mendekati persamaan isotherm Langmuir dengan nilai R2 = 0,9999, diduga proses penyerapan terjadi secara kimisorpsi monolayer. Dari hasil yang diperoleh dapat disimpulkan bahwa semakin lama waktu kontak dan semakin tinggi konsentrasi aktivator maka semakin tinggi kapasitas adsorpsi dan % efisiensi adsorpsi Fe2+ yang diperoleh.

Abstract

Kopi  adalah  salah  satu  tanaman  yang  menghasilkan  produk  samping dalam  proses  pengolahannya yakni  kulit  kopi. Tujuan penelitian ini adalah untuk mengkaji pengaruh waktu delignifikasi dan konsentrasi NaOH pada hasil gula reduksi. Penelitian ini sudah banyak dilakukan sebelumnya menggunakan pelarut etanol dan asam kuat, yang belum dilakukan adalah menggunakan pelarut basa kuat. Penelitian ini menggunakan pelarut NaOH untuk mendegradasi lignin yang terdapat pada bahan baku. Pada proses pretreatment fisika kulit kopi dibersihkan lalu dimasukkan kedalam oven selama 24 jam, tujuannya untuk menghilangkan kadar air, kemudian dihaluskan menggunakan blender agar diperoleh hasil berbentuk serbuk. Proses delignifikasi menggunakan metode organosolv dengan variasi konsentrasi NaOH 1%, 3%, 5% dan 7% dengan variasi waktu delignifikasi 30 menit, 60 menit, 90 menit dan 120 menit. Proses hidrolisis menggunakan katalis H2SO4 1% pada suhu 100oC  selama 4 jam, kemudian diuji yield, densitas dan kadar gula reduksi menggunakan metode luff schrool untuk mengetahui berapa banyak kadar gula reduksi pada kulit kopi arabika. Kadar gula reduksi tertinggi terdapat pada konsentrasi NaOH 7% dan waktu delignifikasi 120 menit sebesar 68,28%. Yield tertinggi terdapat pada konsentrasi NaOH 7% dan waktu delignifikasi 120 menit sebesar 60,98%. Densitas tertinggi terdapat pada konsentrasi NaOH 7% dan waktu delignifikasi 120 menit sebesar 0,985 g/cm3. Hasil penelitian menunjukkan semakin besar konsentrasi NaOH dan lama waktu delignifikasi maka kadar gula reduksi yang dihasilkan akan semakin banyak.

Abstract

Rice straw is one of material containing cellulose to produce Carboxymethyl Cellulose (CMC). CMC is a non toxic polysaccharide that produces from cellulose that widely used in the pharmaceutical, food, textile, detergent, and cosmetic products industries. There are two stages usually use to produce CMC which are mercerization and esterification processes. Rice straw waste is one of the materials to produce CMC, it has a cellulose content of 37.7%, hemi-cellulose 21.99%, and lignin 16.62 %.  BPS Aceh shown that the total rice harvested area was 310.01 hectares, with a total production of 1.71 million tons, and rice produced at 982.57 thousand ton. This study aims to reduce waste and environmental pollution caused by rice straw and collects information of rice straw as a basic material to produce of carboxymethyl cellulose and to increase the economic value of rice straw.  The effects of various wieght parameters sodium monochloroacetate on chemical properties of CMC that produce from rice straw were investigated in this research. Rice straw was collected from a rice field in Nisam, North Aceh. The research conducted by synthesizing 5 grams rice straw for 5.5 hours using NaOH and Sodium Monochloroacetate solutions. With variations weight of sodium monochloroacetate are 5,6,7,8 and 9 grams. The characterization of CMC was carried out by Fourier Transform Infrared (FTIR), CMC yield, DS, Viscosity, water content, pH. The result shows that addition of sodium monochloroacetate was significant factors influence the chemical properties on CMC. The CMC that produced in this study achieved to National Indonesia Standard (SNI).

Abstract

In the development of materials science, especially polymers, natural fibers such as areca nut shell fiber are increasingly attractive to use. The use of synthetic polymer materials made from fiber can replace conventional materials such as metal, wood and leather. They can replace conventional materials with the advantages of lower price, environmental friendliness, and recyclability. Areca nut shell fiber, as an example of a natural fiber, has great potential in the furniture industry, crafts, and as an ingredient in traditional medicine. This fiber is used as a reinforcing material in composites with an Unsaturated Polyester Yukalac resin matrix. Unsaturated Polyester Yukalac resin, with characteristics such as stiffness, flexibility, water resistance, chemical resistance and weather resistance, is used as a matrix in making composites. The aim of this research is to make a plastic composite prototype reinforced with areca palm fiber, varying the volume fraction of areca nut shell fiber by 30%:50%, 50%:60%, 70%:70%, 90%:80% and for the matrix using polyester resin. BQTN 157 EX. The fiber composition is arranged in a mold in the same direction using the hand lay up method. Composite testing is in the form of a tensile test referring to the ASTM 638-03 standard. The results of the largest tensile testing process were with a volume fraction of 50% with an average value of 7.11 MPa, and for tensile testing the lowest was a volume fraction of 70% with an average value of 6.17 MPa, it can be concluded for reinforced plastic composites Areca nut shell fiber has considerable ability to be applied as a structural material. This is a step towards the development of innovative and environmentally friendly composite materials for various industrial applications.
