Abstract

Qur'an explains najis mughallazah be purified using water as much as 7 times and one of which uses the ground. The addition of clay to the soap helps remove impure DNA attached to the surface of the skin. This study was conducted to determine the effect of an increase in the amount of kaolin and reaction temperature on water content and hardness of soap; determine whether the soap formulas meet the quality requirements of SNI and determine whether the soap formula capable of eliminating the derivatives pig DNA using PCR analysis method. The reaction was designed in 4 reaction temperatures (50ºC - 80ºC), the consistency of kaolin (10% - 20%), 35% NaOH concentration, reaction time 10 minutes and the stirring speed of 250 rpm. The results showed that all variations meet SNI standards. The best results were obtained in 15%; 50ºC and 17.5%; 60ºC. First, rinse the soap can eliminate DNA smeared unclean human hands. DNA washing using water and soap shows the remaining conventional PCR DNA electrophoresis. Kaolin solid soap formulation produced may eliminate DNA and meet the standard SNI 06-3532-2016.

Abstract

Najis mughallazah is excrement which comes from pigs which earthen soap can use to purify it.  Method to purify unclean that is necessary to use water seven times and the addition of bentonite to soap is expected to be able to remove unclean Deoxyribonucleic Acid (DNA) that is located on the surface of human skin. The purpose of this study was to determine the effect of the amount of bentonite filler and the reaction temperature on the quality of soap, knowing whether the soap formula meets the SNI quality requirements and knowing whether the soap formula can remove Pig DNA residues using the Polymerase Chain Reaction (PCR) analytical method. In this study, the operation conditions were designed at the reaction temperature (50 oC, 60 oC, 70 oC and 80 oC), bentonite consistency (10%, 12.5%, 15%, 17.5% and 20%), 35% NaOH concentration, reaction time 10 minutes and stirring speed 250 rpm. The analyzes carried out in this study include analysis of water content, free alkaline content, free fatty acid content and PCR method. The best results were obtained for 15% (70 °C) soap that had soap hardness characteristics close to conventional soap and 17.5% (50 °C) soap with the characteristics of soap that could remove najis mughallazah. The resulting solid bentonite soap formula meets the SNI 3523: 2016 standard and can eliminate mughallazah unclean.

Abstract

Tannins are phenolic compounds with considerable abundance in nature. In this study, the extraction of Indian gooseberry fruit was performed using Microwave Assisted Extraction (MAE) method with ethyl acetate as solvent. Two grams of Indian gooseberry fruit were extracted for 1 minute with variable microwave power operation (100, 180, 300, 450 and 600) W. The experiment is continued at the power that gave the highest yield of tannin with  variable ratio sample to solvent (1/10, 1/20, 1/30, 1/40 and 1/50) g/mL. Total tannins in the extract were analyzed using UV-Vis Spectroscopy method to find the yield of tannin. Functional groups that were contained in the extract were analyzed using Fourier-Transform Infrared Spectroscopy (FTIR) method. The results of this study indicate that the extract contains tannins in qualitative tests with gelatin and FeCl3 as well as in FTIR analysis. The highest yield of tannin was 36.86 mg/g which was obtained under conditions of power 100 W and ratio sample with ethyl acetate 1/50 g/mL.

Abstract

Biobriquette is a solid fuel derived from raw materials that can be renewed continuously because it is made from a mixture of biomass such as wood, twigs, leaves, grass, straw and other agricultural wastes. The research aims to examine the effect of variations in the composition of raw materials and particle sizes were 50 mesh, 70 mesh, 100 mesh, and 120 mesh. This research was started by carrying out the pyrolysis process on the raw material with temperature 350 oC for sixty minutes, then the refined pyrolysis charcoal powder was mixed with starch adhesive 10% of the weight of the raw material which was then manually pressed cylindrical. The measurement results in this research were compared with quality parameters based on Indonesian National Standard (SNI), Japan, England, and America. The best result for this research is obtained at a ratio of rubber fruit shells and wood twigs 1:5 with a particle size of 100 mesh, that is with inherent moisture of 4.50%, ash content of 2.19%, volatile matter of 13.73%, density 2.2502 g/cm3, and caloric value 6,653.60 cal/g.
