This helps to understand the mechanism of corrosion inhibition of metals on an atomic and molecular scale. Some of the common computational techniques used are DFT theory, MD and Monte carlo simulations. According to the literature, choosing organic compounds through modeling helps researchers determine the efficiency of the right inhibitor, saving time and money. Another advantage of this computational model is that it can easily determine the active sites/adsorption sites and the orientation of organic compounds. This review discusses indicators of corrosion inhibition contained in several computational models. The mechanism of corrosion inhibition by natural compounds and the types of inhibition of compounds are also discussed through polarization potentiodynamics.","PeriodicalId":159745,"journal":{"name":"Jurnal Penelitian Dan Pengkajian Ilmiah Eksakta","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114388050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the ingredients that can be used as an antibacterial product is black cumin seed oil (Nigella sativa oil), it is known that black cumin seed oil contains Thymoquinone and α-pinen which are efficacious as antibacterial. This research aims to produce a cosmetic preparation in the form of a face wash that effectively cleans the skin from dust and dirt from makeup, as well as preparations that have antibacterial activity against Staphylococcus epidermidis by using the well diffusion method. Black cumin seed oil is formulated into facial foam in several concentrations, namely 3% (FI), 5% (FII) and 7% (FIII). Evaluation of fa cial foam preparations includes examination of organoleptic, pH, foam power, skin irritation, homogeneity, wetting power, alcohol insoluble portion, freeze and thaw, examination of mineral oil, washability and antibacterial activity. Data analysis using One Way ANOVA statistical test and descriptive. The result showed that the physical stability test, the three facial foam formulas have good physical stability and meet the pH requirements of topical cosmetic preparation. In the antibacterial activity test, it was found that the facial foam preparation of black cumin seed oil give inhibition of 15.37 mm (FI), 16.52 mm (FII) and 17.25 mm (FIII). Based on the one way ANOVA statistical data, the p value <0,05 which means that three is a significant difference in inhibition diameter between FI, FII and FIII which negative control and positive control.
