Abstract

Kebutuhan gula nasional yang tinggi tidak sebanding dengan produksi dalam negeri mendorong eksplorasi bahan baku alternatif untuk produksi glukosa cair. Umbi suweg (Amorphophallus campanulatus) sebagai tanaman lokal dengan kadar pati tinggi, memiliki potensi besar untuk dimanfaatkan sebagai bahan baku pembuatan glukosa cair. Penelitian ini bertujuan untuk mengetahui pengaruh variasi waktu sakarifikasi (2-6 jam) dan kecepatan pengadukan (200-400 rpm) terhadap kadar glukosa dan kadar air dalam glukosa cair dari hidrolisis pati umbi suweg menggunakan metode enzimatis. Proses hidrolisis diawali dengan pembuatan pati dari umbi suweg, dilanjutkan likuifikasi dengan enzim α-amilase, dan sakarifikasi menggunakan enzim glukoamilase. Hasil menunjukkan bahwa peningkatan waktu sakarifikasi dan kecepatan pengadukan berbanding lurus dengan kadar glukosa yang dihasilkan dan menurunkan kadar air. Kadar glukosa tertinggi tercapai pada kondisi 6 jam dan kecepatan 400 rpm dengan nilai sebesar 27,5 °Brix. Namun, nilai ini belum memenuhi standar SNI yakni sebesar 70 °Brix. Kadar air yang dihasilkan berada dalam kisaran 7,229-18,139%, yang masih memenuhi batas maksimal menurut SNI 01-2978-1991. Penelitian ini menunjukkan bahwa umbi suweg memiliki potensi sebagai bahan baku alternatif dalam produksi glukosa cair, di mana waktu sakarifikasi serta kecepatan pengadukan merupakan faktor signifikan dalam meningkatkan hasil glukosa. Penelitian lanjutan disarankan untuk memperpanjang waktu sakarifikasi agar mencapai kadar glukosa yang sesuai standar.

Abstract

Furfural is a valuable furan-based organic compound widely used in the chemical and pharmaceutical industries, and as an intermediate in the production of furfuryl alcohol and furanone. However, Indonesia still relies on imports due to the absence of local furfural producers. Rice husk, an abundant agricultural waste rich in pentosan, offers promising potential as an alternative raw material. This study aims to determine the kinetic equation for furfural formation from rice husk (Oryza sativa) using a two-stage method with sulfuric acid as a catalyst. The process involves hydrolysis of pentosan into pentose, followed by dehydration into furfural. Temperature (80–100 °C) and reaction time (20–60 minutes) variations were applied to observe their effect on furfural concentration, analyzed using the iodometric titration (Excess Iodine Method). Results show that the reaction follows first-order kinetics, with linear graphs and R² values approaching 1. Furfural concentration increased with both temperature and time. The activation energy obtained was 21.62 kJ/mol and the pre-exponential factor (k₀) was 14.26. This study confirms that the two-stage method is more effective in enhancing furfural production from rice husk biomass.

Abstract

Corn silk, a part of the maize plant that plays a role in pollination, is often considered agricultural waste and has not been optimally utilized. However, it contains bioactive compounds with potential antimicrobial properties. The main problem addressed in this study is the underutilization of corn silk as a source of valuable bioactive compounds, particularly flavonoids and alkaloids, which can be developed for health-related applications. This research aims to investigate the effect of extraction temperature and time variations on the levels of flavonoid compound 9,12-Octadecadionic Acid (Z,Z)-, Methyl Ester and alkaloid compound 6-(Dimethylnitroryl)-4,4-Diphenyl-3-Heptanone in corn silk extract. The method used was maceration with 80% ethanol as the solvent, followed by analysis to determine the optimum conditions. The results showed that the optimum condition for 6-(Dimethylnitroryl)-4,4-Diphenyl-3-Heptanone was achieved at 50°C for 5 hours, yielding a concentration of 21.57%. Meanwhile, the optimum condition for 9,12-Octadecadionic Acid (Z,Z)-, Methyl Ester was obtained at 40°C for 5 hours, with a concentration of 21.62%. These findings indicate that corn silk has promising potential as a source of bioactive compounds, offering added value for agricultural waste utilization. Furthermore, this study provides implications for the development of corn silk–based products with economic and health benefits.

Abstract

The frigate tuna (Euthynnus affinis) is known for its high protein content in the head, making it suitable for the production of protein concentrate used in animal feed. This research aims to investigate the influence of adding a methanol-acetone mixture solvent, the duration of the extraction process, and the protein content in the resulting concentrate using the Kjeldahl method. The protein concentrate is produced through the maceration extraction method, where 30 grams of the frigate tuna head sample is mixed with a methanol-acetone solvent in various ratios (1:9; 3:7; 5:5; 7:3; 9:1) at a temperature of 50 °C and a stirring speed of 500 rpm, with extraction times ranging from 2 to 6 hours. Subsequently, filtration is performed, and the precipitate is dried using an oven at 100 °C for 30 minutes. The dried sample is then subjected to protein content testing using the Kjeldahl method. Research results indicate that both protein content and extraction yield values increase with the duration of the extraction process, while the water content decreases. The optimal result in maceration extraction is achieved with the methanol-acetone mixture (9:1) treatment and a 6-hour extraction time, yielding a protein content of 89.15 %, water content of 5.57 %, and an extraction yield of 23.86 %.Protein concentrate can be used as animal feed to increase protein needs. Animals that are given sufficient protein will fatten and make the animal healthy

Abstract

The synthesis and characterization of cellulose acetate were carried out using cellulose derived from corn stalks. Cellulose acetate was obtained through the esterification of cellulose, a natural biopolymer commonly sourced from wood or plant fibers. During the acetylation stage, the hydroxyl groups in cellulose were replaced with acetate groups from acetic anhydride. The acetylation process involved varying the volume of glacial acetic acid (CH₃COOH) at 25, 35, 45, 55, and 65 milliliters and reaction times of 1, 1.25, 1.5, 1.75, and 2 hours, using 0.5 milliliters of 98 percent sulfuric acid as a catalyst. Cellulose was first extracted by delignification using 17.5 percent sodium hydroxide, followed by bleaching with 4 percent sodium hydroxide and 4 percent hydrogen peroxide. The results showed that increasing the volume of acetic acid led to an acetyl content of up to 40.4 percent and a degree of substitution of 2.5. Extension of the acetylation time to 1.5 hours also increased the yield of cellulose acetate to a maximum of 70.2631 percent before decreasing at longer durations. These optimal results, including 70.2631 percent yield, 40.4 percent acetyl content, and a degree of substitution of 2.5, were achieved with 65 milliliters of acetic acid and 1.5 hours of acetylation. FTIR analysis confirmed successful acetylation by identifying hydroxyl (O–H), carbonyl (C=O), and ester (C–O) functional groups.

Abstract

The production of ethanol from molasses generates vinasse as a by-product of the distillation process. Vinasse waste produced by PT Energi Agro Nusantara contains COD and BOD levels of 910.5 ppm and 460.5 ppm, respectively, which significantly exceed the maximum limits set by wastewater quality standards, necessitating treatment. One treatment method is the use of Advanced Oxidation Processes (AOPs), which utilize hydroxyl radicals to oxidize organic pollutants in vinasse. One such process is the electro-Fenton process. In this study, 500 ml of vinasse was placed in a beaker and stirred for 90 minutes. A 25 ml addition of hydrogen peroxide was made, with a 2 cm gap between the iron electrode plates. Voltage variations of 3V, 6V, 9V, and 12V, along with electrode thicknesses of 2 mm, 3 mm, 4 mm, 5 mm, and 6 mm, were tested. COD and BOD levels were analyzed using the titrimetric method. The results showed that increasing the voltage and electrode thickness reduced COD and BOD levels, while the percentages of COD and BOD removal increased. The highest voltage (12V) and electrode thickness (6 mm) yielded the lowest final COD and BOD values of 163.5 ppm and 88.9 ppm, respectively, with COD removal at 82% and BOD removal at 81%.
