Abstract

Used cooking oil or often referred to as used cooking oil is one of the needs for food processing for humans. Repeated processing of cooking oil in the frying process can reduce the quality of the cooking oil. Therefore, one of the efforts to process used cooking oil is adsorption using activated charcoal from kepok banana peels. The use of activated charcoal as an adsorbent can be beneficial because activated carbon can absorb some unwanted odors and reduce the amount of free fatty acids, thereby improving the quality of the oil. The purpose of this study was to study the addition of the amount of kepok banana skin size of activated charcoal (mesh) with adsorption time on the quality of used cooking oil. The variables used were varying the size of the activated carbon particles of 100 mesh, 120 mesh, 140 mesh and 160 mesh with adsorption times of 3 hours, 5 hours and 7 hours. The refined oil will be analyzed for oil density, fatty acid content in the oil, and water content. From the research results it is known that the best particle size is 160 mesh. The density value is 0.889 g/ml. The results obtained are that the density value still does not meet the SNI (2002) cooking oil quality standard requirements, namely 0.900 g/ml. FTIR analysis shows that there is an increase in wave number which is the peak of the OH (hydrogen bond) structure using purified chorcoal. The C=O (carboxylate) FFA molecule is shown around the wave number 1060 cm-1 increasing to 1070 cm-1. Keywords: Adsorption, activated charcoal, kepok banana, free fatty acid (FFA), water content, density

Abstract

Styrofoam is one type of food packaging that we often find. Styrofoam has excellent heat and cold resistance so it is used as an insulator. The ability to withstand good temperatures, lightweight and practical encourages the use of styrofoam as a food and beverage packaging material. However, Styrofoam contains many harmful substances and is not environmentally friendly. One solution is to replace the material for making styrofoam which is environmentally friendly called biodegradable foam. Sugarcane bagasse fiber has the potential as a basic material for making biodegradable foam. The purpose of this experiment is to determine the effect of the addition of bagasse fiber on the characteristics of biodegradable foam. This experiment uses a complete randomized design method with sugarcane bagasse fiber concentration treatment. The characteristic tests carried out include tensile strength test, water absorption test, biodegradation test, and thermogravimetric analysis. From the results of bagasse fiber decomposed 9,130 mg and still remaining 1,13 mg. The optimum concentration of biodegradable foam bagasse fiber on water absorption, biodegradation rate, and tensile strength in the 90:10 composition sample. The results of functional group analysis showed O-H and C-O groups which indicated that biodegradable foam is easily degraded by microorganisms in the soil. Keywords: Biodegradable foam, bagasse, cassava starch, packaging.

Abstract

ABSTRACTNitrogen is a basic compound in the chemical industry. Nitrogen is an inert gas compound so it is suitable for various applications covering various aspects of manufacturing, processing, handling and shipping chemicals. The aim of this research is to analyze the influence of impurities, pressure and air flow rate on the purity of nitrogen gas products produced using the Pressure Swing Adsorption (PSA) method, then carry out a comparison or simulation of actual field data with Aspen Adsorption V.10. The research method used is descriptive qualitative, the data in this research is field operational data and data collection techniques are carried out periodically through data log sheets. From the research results, it was found that Purity in October to November 2023 on October 5 and 27 was 99.98%, with a flow of 52.2 Nm3/h, while for November there was 98.01% (purity) with flow 105.0 Nm3/h. And after carrying out simulations using Aspen Adsorption V.10 and varying the input data, Purity was obtained at 99.98%, 99.97%, 99.91% with a flow of 100 Nm3/h, 150 Nm3/h, 200 Nm3/h or 0, 4461 kmol/s, 0.6692 kmol/s, 0.8992 kmol/s in Aspen Adsorption V.10 applications.Keywords: Nitrogen, Pressure Swing Adsorption (PSA), Aspen Adsorption, Carbon Molecular Sieve (CMS)

Abstract

ABSTRACT Making lotion from Virgin Coconut Oil (VCO) and Aloe Vera to which an emulsifier has been added requires antimicrobial ingredients, because the water phase facilitates the growth of microorganisms. The presence of methyl paraben preservative is very important in oil-in-water emulsions, because the shelf life of the product will last longer. This research aims to determine the effect of span 60 on homogeneity properties. The physical properties of the lotion include homogeneity test, pH test, viscosity test and specific gravity test based on SNI-16-3499-1996. The experimental process was carried out with varying weights of span 60 (sorbitan monostearate) 1 mg, 3 mg, 5 mg, 7 mg, methyl paraben with varying weights of 1.5 mg, 2 mg, 2.5 mg, 3 mg and a stirring time of 21 minutes. With the liquid phase and the heated oil phase.0.95- 1.05 g/ml. Keywords: Virgin Coconut Oil (VCO), Aloe Vera, Emulsifier, Span 60 (Sorbitan Monostearate), Methyl Paraben, Homogeneity.

Abstract

ABSTRAK Penelitian tentang pembuatan asam asetat dari limbah cair kulit kopi (coffea arabika. Sp) telah dilakukan. Limbah cair kulit kopi dapat dimanfaatkan untuk menghasilkan asam asetat, dan diharapkan dapat menghasilkan mutu asam asetat yang baik sesuai dengan standar mutu asam asetat dari nira aren (Arenga pinnata) SNI 01-4371-1996. Proses fermentasi dilakukan dalam dua tahapan, tahap pertama adalah fermentasi limbah cair kulit kopi menjadi alkohol secara anaerob, tahap kedua adalah fermentasi alkohol menjadi asam asetat secara aerob. Fermentasi secara aerob dilakukan dengan memvariasikan penambahan bakteri acetobachter aceti dan tanpa penambahan acetobachter aceti, serta variasi waktu yaitu selama 7, 10, dan 15 hari. Hasil penelitian menunjukkan bahwa asam asetat yang diperoleh tanpa penambahan bakteri A. Aceti tidak memenuhi standar mutu sedangkan dengan penambahan bakteri A. aceti telah memenuhi standar mutu yaitu: kadar asam asetat: 6,48%, kadar alkohol: 4,35%, TPT: 1,27%, pH: 4 dan cemaran logam (Pb: -0,3116, Cu: -0,7397, Zn: - 0,5623).Keywords: fermentasi, kopi, Acetobachter aceti, SNI 01-4371-1996.
