Abstract

Brown rice contains anthocyanin compounds. Antosianin is a natural pigment that gives red color to brown rice. Anthocyanin is an unstable compound, so it is necessary to optimize the extraction method to find out the proper extraction method in obtaining the largest anthocyanin level in brown rice. Optimization of extraction conducted in this study include, solvent, addition of HCl and size of brown rice Measurement of levels in this study using the method of differential pH with visible spectrofotometer tool. Determination of levels that have been done obtained anthocyanin levels on samples of fine methanol rice, intact methanol, 1% HCl 1% methanol and 1% HCl 1% respectively are 0.0591 (mg / 100g), 0.0551 (mg / 100g), 0.1503 (mg / 100g), and 0.1212 (mg / 100g) respectively, . The results obtained by the fine rice samples dissolved with 1% HCl methanol had the highest anthocyanin levels.

Abstract

Red ginger rhizome (Zingiber officinale Roscoe var. Sunti) is one of the herbs that is widely used as traditional medicine. The present study was to determine the secondary metabolites contained in red ginger rhizome plants and antibacterial activity against Staphylococcus aureus and Escherichia coli bacteria. A total of 483.2 grams of red ginger powder was extracted by maceration method obtained from ethyl acetate extract 15.85 g. Antibacterial activity of red ginger extract against S. aureus and E. coli using microdilution method showed that ethyl acetate extract could inhibit S. aureus growth by MIC (Minimum Inhibitory Concentration) 6.3% and MBC (Minimum Bactericidal Concentration) 25% and extract Ethyl acetate red ginger rhizome can Minimum MIC (E. Inhibition Concentration) E. coli with a minimum inhibitory concentration of 25% and MBC (Minimum Bactericidal Concentration) 50%. The results showed that the red ginger rhizome ethyl acetate extract was the most influential and had more potential to inhibit the growth of Gram positive bacteria compared to inhibition of Gram negative.

Abstract

Cassava peels contained carbon elements about 59.31%, it became the base of using cassava peels as activated carbon. One of utilization of activated carbon was adsorption metal lead. Production of activated carbon was conducted in 3 steps were dehydration, carbonation and activation. Study had been conducted by comparing characteristic of activated carbon without activator and activated carbon with variation of KOH concentration as activator were 0.2 M; 0.4 M and 0.6 M so that could be known the optimal KOH concentration. Characteristic testing was conducted for water content, ash content, adsorption of iodium and adsorption of methylene blue also adsorption of lead metal. Measuring of adsorption metal lead was done by Atomic Absorption Spectroscopy. Experiment result shows activated carbon with KOH 0.4 M has best characteristic by water content 3.79%, ash content 8.09%, adsorption of iodium 863 mg/g and adsorption of methylene blue 3116 mg/g also adsorption of metal lead 98%.

Abstract

Kalkon is a secondary metabolite of the flavonoid group that is found in nature, especially in plants. Kalkon has various activities such as cytotoxic, antiviral, anesthetic, antimicrobial, antiinflammatory, and so forth. The aim of this research is to know the antibacterial activity of kacco-based derived paracetamol compound by using docking method against bacterial protein Escherichia coli and Bacillus subtilis. The results showed that the compound 3- (4-Metoxyphenyl) -N- (4-Chlorophenyl) Acrylamide, 3- (4-Hydroxyphenyl) -N- (4-Chlorophenyl) Acrylamide, and 3- (4-Hydroxy-3-Methoxyphenyl ) -N- (4-Chlorophenyl) Acrylamide showed good activity with an average rmsd-refine score <2. The kalkon derivative binds complex with amino acid bacteria such as Ile 173, Asn 267, Lys A449, Thr 265, and Arg A389.

Abstract

Rice husk has the content of organic and inorganic compounds that have not been utilized maximally, one of them is silica. High silica content in rice husks can be used as an alternative source of potential silica for the synthesis of calcium silicate as a base material of Trioxide Aggregate mineral composites in tooth biocement. In this study, calcium silicate was obtained through two stages of the process, namely silica isolation from rice husk ash by sol-gel method, and reacting between silica and calcium oxide. Silica and calcium oxide are reacted to the mole ratio between silica to calcium oxide of 7:3, 6:4, 4:6, and 3:7. The isolated silica is characterized by the distribution of the size and composition of each element with Particle Size Analyzer (PSA) and EDS. The formation of calcium silicate and its size distribution from the synthesis stage is determined by XRD and PSA. The result showed that silica isolation from rice husk ash with sol-gel method obtained silica with content and particle size of 71.6% and 52.82 mm. While the optimum condition of calcium silicate synthesis was achieved at the mole ratio of silica to calcium oxide by 4:6. In the mole ratios obtained calcium silicate type b-dicalcium silicate with an average particle size of 102.2 mm.

Abstract

Dental plaques are formed by biofilms that cover the surface of the tooth. Biofilm is a mucous layer consisting of millions of bacterial cells, saliva and food scraps. When biofilm formation is out of control, it will easily thicken on the tooth surface called plaque. This biofilm is a good place for colonization and growth of various types of bacteria, one of which is the Sterpotococcus mutans bacteria. S. mutans bacteria can form colonies that are firmly attached to the tooth surface and are cariogenic bacteria that are able to ferment sucrose (carbohydrates) into acid, reduce the pH of the tooth surface and cause tooth mineralization. So for the control of these bacteria, preparations containing antibacterials are used, one of which is natural ingredients, namely Kecombrang. The aim of this study was to determine the antibacterial activity of the Etlingera elatior (Jack) R.M.Sm. stem extract extracted by solvent based on the level of polarity. Antibacterial activity testing of extracts was divided into 5 groups, namely for n-hexane, ethyl acetate, ethanol extract 20, 40, 60 and 80%, positive control of minosep and negative control (DMSO). The test results showed that E. elatior (Jack) RMSm.) contained secondary metabolites of flavonoids, tannins, saponins, triterpenoids and alkaloids, ethyl acetate extracts with concentrations of 20, 40, 60 and 80%, having strong antibacterial activity against S. mutans of 17.22; 17,55; 17.77 and 18.55 mm, higher than the positive control of Minosep which has antibacterial activity of 16.55 mm.

Abstract

Salicylic acid is an anti-acne as well as keratolytic which is commonly given topically. The purpose of this study was to determine the levels of salicylic acid in anti-acne creams circulating in traditional markets, supermarkets, and skin care in Bandung, and to compare the levels of salicylic acid in samples with the maximum salicylic acid content limit determined by the Center for Drug and Food Control (BPOM). Qualitative analysis using the thin layer chromatography (TLC) method with the toluene mobile phase: acetic acid (4: 1) and color test using FeCl3 reagent. While the quantitative analysis of salicylic acid in anti-acne cream using ethanol solvent and measured by a UV spectrophotometer. Method validation to prove that the method used has reached the requirement. Salicylic acid levels in sample G were 2.33%, C 1.54%, B 0.71%, R 0.85%, and I 0.82%. Samples C, B, R and standard sample set by BPOM which is no more than 2%. Sample G does not unqualified because the level is more than 2%.
