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

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 merupakan metabolit sekunder dari golongan flavonoid yang banyak ditemukan di alam terutama pada tumbuh-tumbuhan. Kalkon memiliki berbagai aktivitas seperti sitotoksik, antivirus, anestesi, antimikroba,  antiinflamasi, dan lain sebagainya. Tujuan penelitian ini adalah untuk mengetahui aktivitas antibakteri senyawa turunan kalkon berbasis parasetamol dengan menggunakan metode docking terhadap protein bakteri Escherichia coli dan Bacillus subtilis. Hasil penelitian menunjukkan bahwa senyawa 3-(4-Metoksifenil)-N-(4-Klorofenil) Akrilamida, 3-(4-Hidroksifenil)-N-(4-Klorofenil) Akrilamida, dan 3-(4-Hidroksi-3-Metoksifenil)-N-(4-Klorofenil) Akrilamida menunjukkan aktivitas yang baik dengan rata-rata skor rmsd-refine <2. Turunan kalkon tersebut berikatan kompleks dengan asam amino bakteri seperti Ile 173, Asn 267, Lys A449, Thr 265, dan 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

Asam salisilat merupakan zat anti jerawat sekaligus keratolitik yang lazim diberikan secara topikal. Tujuan penelitian ini adalah untuk mengetahui kadar asam salisilat pada krim anti jerawat yang beredar di pasar tradisional, swalayan, dan skin care Kota Bandung, dan membandingkan kadar asam salisilat dalam sampel dengan batas kandungan asam salisilat maksimum yang ditentukan oleh Balai Besar Pengawas Obat dan Makanan (BPOM) yaitu < 2%. Analisis kualitatif menggunakan metode kromatografi lapis tipis (KLT) dengan fase gerak toluen : asam asetat (4:1) dan uji warna menggunakan pereaksi FeCl3. Sedangkan analisis kuantitatif asam salisilat pada krim anti jerawat menggunakan pelarut etanol dan diukur dengan spektrofotometer UV. Validasi metode dilakukan untuk membuktikan bahwa metode yang digunakan telah memenuhi persyaratan. Kadar asam salisilat dalam sampel G adalah 2,33% , C 1,54 %, B 0,71%, R 0,85 %, dan I 0,82%. Sampel C, B , R dan I memenuhi persyaratan yang telah ditetapkan oleh Balai Besar Pengawas Obat dan Makanan (BPOM) yaitu tidak lebih dari 2%, sedangkan sampel G tidak memenuhi persyaratan yang telah ditetapkan karena kadarnya lebih dari 2%.
