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

Mangrove Apple (Sonneratia caseolaris) is a fruit native from tropical area that has antioxidant activity. This study aims to produce transparent soap with pedada fruit antioxidant enhancing agents and the observation of transparent soap quality in accordance with SNI 03-3532-1994 and antioxidant activity of transparent soap. Research began with pre-treatment process, namely extraction of mangrove apple enhancing agent by maceration and infundation method using methanol and water solvent. The obtained extracts were then added as variation of coconut oil soap production formula. The obtained soaps were then tested for free alkali rate, free fatty acid rate, moisture content, foam stability, pH and antioxidant activity by DPPH method. The antioxidant activity of the obtained soap shows that with the formulation by 0.5 g of methanol maceration extract of mangrove apple resulted in soap with IC50 antioxidant activity of 122.30 μg/mL.

Abstract

Bacterial cellulose (BC) is biomaterial from bacterial fermentation that contain high purity of cellulose, but 90% of BC pellicles retained water from the fermentation process. In this study, BC was modified with glycerol immersion in different concentrations (0%; 2,5%; 5%; 7,5%; 10%). For wide application, water content on BC must be removed by drying. Various oven drying condition are temperature 80 °C and 120 °C and time 60 minutes. The physical and mechanical properties of the dried BC biofilm were determined including tensile strength and elasticity. BC biofilm bound was identified by FTIR and EDX. The results showed that glycerol concentration was able to increase biofilm elasticity from 3.46% to 27.743%. However, glycerol immersion above 7.5% caused a decrease in the tensile strength of BC biofilm. The drying variation of 120 °C produces the highest tensile strength of 7.161 MPa when soaked in 7.5% glycerol. The drying variation of 80 °C produced a biofilm with the best elasticity of 27.473%. The results of FTIR and EDX analysis confirmed that there were differences in the contents of the modified BC.
