Abstract

CV. Aceh Raya Banda Aceh is a company engaged in the contractor and supplier sector which has a large number of transactions both from purchasing and project management, but recording transactions that occur every day still uses the manual method, this sometimes makes financial reports with various types of transactions seem sluggish to the owner, the author only discusses the problem of the Financial Report Information System on the CV. Aceh Raya Banda Aceh using web-based. The research objective was to identify and design a financial reporting information system at CV. Aceh Raya Banda Aceh web-based. The collection of data needed in writing this research was obtained by two methods, namely literature studies related to library books and other scientific works, field studies by carrying out interviews and direct observation of objects related to this research as well as the system development method. used is the waterfall method. Financial Report Information System on CV. Aceh Raya Banda Aceh is carried out by one of the administrative staff and assisted by 2 (two) administrative staff in the field of administration to record and input transaction data. From the results of the study it can be concluded that the Financial Report Information System at CV.

Abstract

Red betel leaf (Piper crocatum Ruiz & Pav) is a plant that grows widely in the Puruk Cahu area of Central Kalimantan and is empirically used as an antiseptic to treat wounds. Red betel leaves contain flavonoid compounds that have antiseptic activity.   Objective: To determine the total flavonoid content at the fraction level of red betel leaf extract using the UV-Vis Spectrophotometry method.  Methods: Experimental method by looking at qualitative data results through color reaction tests and quantitative data to see the effect of total flavonoid levels using UV-Vis Spectrophotometry.  Results: Qualitative analysis of flavonoid compounds using a color reaction test showed positive results containing flavonoids. Quantitative analysis using UV-Vis Spectrophotometry showed that the total flavonoid content of the n-Hexane fraction, ethyl acetate fraction and distilled water fraction was 38 mg QE/g or 3.8%; 42.8 mg QE/g or 4.28%; and 25.6 mg QE/g or 2.56%. The highest total flavonoid levels were found in the ethyl acetate fraction. The results of the One Way Annova test obtained a significance value of 0.000 (p<0.05).  Conclusion: Red betel leaf extract at fraction levels contains flavonoid compounds with total flavonoid levels in the n-Hexane fraction, ethyl acetate fraction and distilled water fraction respectively 38 mg QE/g or 3.8%; 42.8 mg QE/g or 4.28%; and 25.6 mg QE/g or 2.56%, so it was concluded that there was a significant influence of total flavonoid levels on the fraction level of red betel leaf extract using UV-Vis spectrophotometry.

Abstract

Background: Free radical exposure poses significant threats to public health by damaging cells and causing degenerative diseases like cancer and premature aging. Antioxidants are vital in neutralizing these radicals. Jatropha curcas L. leaves contain bioactive compounds with promising antioxidant and wound healing properties, warranting evaluation in a practical gel form. Methods: This study used a true experimental design with a posttest-only control group; quercetin was the control, while the treatment groups received different gel formulations of Jatropha curcas L. leaf extract. Results: The pure extract had very strong antioxidant activity (IC50 0.32 ppm). Gel formulations (Formula 2 and Formula 3) also exhibited strong antioxidant activity, with IC50 values of 30.90 ppm and 35.85 ppm, respectively; Formula 2 performed better. Quercetin showed strong activity at 1.22 ppm. One-way ANOVA (p < 0.01) confirmed significant differences between groups. Conclusions: The Jatropha curcas L. leaf extract gel has significant antioxidant potential and is effective in preventing oxidative damage, supporting its use in safe, gel-based herbal skin products.
