Abstract

Naftalena merupakan salah satu polutan yang sulit untuk didegradasi karena termasuk kedalam kelompok PAH dan bersifat karsinogenik. Tujuan dari penelitian ini adalah untuk menguji efektifitas isolat fungi indigen dari Provinsi Riau untuk mendegradasi senyawa toksik naftalena dengan penambahan glukosa sebagai kosubstrat pertumbuhan. Degradasi naftalena oleh isolat fungi dipengaruhi oleh beberapa parameter, diantaranya biomassa, pH dan persentase degradasi yang diukur pada 0, 4, 8, 12 dan 16 hari inkubasi. Berdasarkan dari parameter biomassa isolat fungi Penicillium sp. LBKURCC153 mengalami fase eksponensial sampai hari ke-16. Pada fase eksponensial terjadi pertambahan jumlah sel secara maksimum yang menunjukkan respon positif terhadap penggunaan glukosa dan naftalena sebagai sumber karbon dan energi. Isolat mengalami penurunan pH dari 7 sampai 3,8 yang artinya ada aktivitas pertumbuhan yang menghasilkan asam-asam organik dari proses degradasi naftalena. Isolat juga mampu mendegradasi naftalena sebesar 27,5% oleh Penicillium sp. LBKURCC153 pada media dengan penambahan glukosa pada waktu optimum selama 4 hari inkubasi. Kesimpulannya, penambahan kosubstrat glukosa dapat meningkatkan persentase degradasi naftalena oleh Penicillium sp. LBKURCC153

Abstract

Chemistry cannot be separated from laboratory experiments as a form of increasing understanding and proof of the chemical theory. The problem is that chemical practices require a very large budget and high handling facilities, equipment facilities, chemicals and storage facilities. So there is a new learning method that uses Chemcollective's Virtual Chemistry Laboratory Technology Application by simulating a chemical lab in a computer application called Virtual Lab / Vlab. This is intended to facilitate the understanding of chemistry through practical simulation and solving solutions for the limitations of laboratory equipment. The method used is the stage of software installation and training to practice the chemicals with Vlab. Learning practicum objects with Vlab is one of them is Acidimetry and Stoichiometry. Stoichiometry is chemistry that studies quantitative relationships between substances involved in chemical reactions. Acidimetric titration is the process of determining the concentration of bases using acid solutions as a standard. On Acidimetri Pre Test 54 and Post Test 70, object Stoichiometry Pre Test 80 and Post Test 81. The significant results of the Post Test versus Pre Test in training at SMAN 1 BungarayaSiak have shown that the Vlab method can improve students' understanding of the concept of chemistry. and it was concluded that the Vlab was very good for further introduction, study and application at different schools.

Abstract

This study was aimed to conduct the inhibitory activity of the MAO-A enzyme (PDB ID: 2Z5Y) by the active compounds of Areca catechu L. The method used is in silico approach using AutoDock Vina, PyMol, and Discovery Studio (DSV). The prediction of pharmacokinetic properties and drug-likeness used the Swiss-ADME online website. The docking results exhibited guvacoline has a binding free energy value of -5.9 kcal / mol compared to homoarecoline (-5.4 kcal / mol), and positive control (-5.7 kcal / mol). Guvacoline compounds have a hydrogen bond in the active site of the enzyme. Areca nut compounds obtained good results on pharmacokinetic properties, but not so good on the BBB parameter. The compounds obtained good results for the parameters of the Lipinski, Veber rule, bioavailability score, but the guvacoline compounds could not meet Ghose's rule. The results of the bioavailability radar showed that the compounds have properties as oral drug.

Abstract

Riau Province is one of the largest producing areas of crude oil. Drilling and refining petroleum often produce waste crude oil in large quantities. One method that can be used to degrade waste is biodegradation using a consortium of microorganisms. This study examined the effectiveness of a consortium of indigenous bacteria in degrading hydrocarbon compounds. Growth tests and the ability of isolates to degrade hydrocarbons were carried out by inoculating isolates in liquid Bushnell Haas media containing crude oil of about 5% and incubating for 16 days. The potency of the indigen bacterial consortium during the degradation process is influenced by several parameters, including pH, OD (Optical Density), dan CO2 observed on days 0, 4, 8, 12 and 16 days of incubation. KB4 is the superior consortium in degrading hydrocarbon crude oil. Based on the analysis using GC-MS instruments, the bacteria consortium can degrade two hydrocarbon compounds in crude oil.

Abstract

Naphthalene is one of the pollutants that is difficult to degrade because it belongs to the PAH group and it was carcinogenic. The purpose of this study was to test the effectiveness of an indigenous fungi isolate from Riau Province to degrade naphthalene toxic compounds with glucose as growth cosubstrate. Naphthalene degradation by fungi isolates was influenced by several parameters, including biomass, pH and percentage degradation measured at 0, 4, 8, 12 and 16 days of incubation. Based on biomass parameters, the isolate of Penicillium sp. LBKURCC153 experienced an exponential phase until the 16th day. In the exponential phase, the maximum number of cells increases which shows a positive response to the use of glucose and naphthalene as the carbon and energy source. Isolate decreased their pH from 7 to 3,8, that mean proves the growth activity produce organic acid metabolites of degrade naphthalene. Isolate were also able to degrade naphthalene respectively 27,5% by Penicillium sp. LBKURCC153 in medium with glucose at optimation time until 4 th day incubation. In conclusion, glucose cosubstrate can increase naphthalene degradation percentage by Penicillium sp. LBKURCC153.
