Analisis Produksi Biogas Berdasarkan Bahan Baku Limbah Kotoran Sapi, Serbuk Gergaji, dan Effective Microorganisme-4 (EM4)
Authors: Adrianto Mario Dwi 
Published: September 2019

Biogas is an alternative energy made from organic waste. Organic waste which is often used as raw material for biogas is cow dung. Cow manure is used as raw material for biogas because the cellulose content in it is quite high and its availability is relatively large. However, if only one material is used, the optimum C / N ratio will not be achieved. If the optimum C / N ratio is achieved, the gas produced in biogas production will also increase. One way to get the optimum C / N ratio is by adding biogas filling material. In this study, variations in the composition of biogas filling materials were carried out, namely (1) cow dung, (2) cow dung and sawdust, and (3) cow dung, sawdust, and EM4. Of the three variations of this filling material, measurements of temperature, gas pressure, and pH will be carried out. The purpose of this study was to determine the effect of the composition of the biogas mixture on the variables of temperature, gas pressure, and pH. The biogas production process were divided into several stages, such as mixing filling material, inputting filling material into the digester, fermentation process, taking the data of observation, and analyzing the data. The results showed that differences in the composition of biogas raw materials affected the variable temperature and gas pressure. As for pH, the composition of the filling material does not have a significant effect.

Darkening of the skin results from excessive production of melanin in the skin caused by an increase in tyrosinase related protein 1 enzyme activity. Catechins are flavonoid compounds which contain antioxidants. This study aims to determine the affinity and mechanism of catechins as skin lightening agents by inhibiting tyrosinase related protein 1 target proteins in silico using molecular docking methods. The study was carried out exploratively with the stages of preparing a database of 3D structures of catechins and tyrosinase related protein 1, optimization of 3D structure of catechins, protein preparation, validation of molecular docking methods, and docking of catechins in tyrosinase related protein 1. Docking results are assessed from the bonding energy and hydrogen bonds formed between catechins and proteins. The smaller the bond energy value, the stronger the bond between the catechins and proteins. The results showed that catechins had activity as skin lightening agents because they were able to inhibit the tyrosinase related protein 1 with a bond energy value of -6,35 Kcal/mol. The energy value of the catechin bond with the tyrosinase related protein 1 is smaller than the tyrosinase related protein 1 with its native ligand. This shows that catechins have greater potential and affinity in inhibiting the tyrosinase related protein 1 enzyme with hydrogen bonds on amino acid residues, namely ARG374. Based on the results obtained, catechins have activity as skin lightening agents with the mechanism of inhibiting the tyrosinase related protein 1 enzyme so that the amount of eumelanin formed is less and the skin becomes brighter.
