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. Aceh Raya Banda Aceh has followed the procedures and used a computer with a web-based programming language and MySQL as the database

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.

Abstract

Tempuyung (Sonchus arvensis L.) leaves are traditionally used as medicinal material and contain flavonoid compounds whose recovery may vary according to solvent polarity during extraction and fractionation. This study determines the total flavonoid content of the aqueous, ethyl acetate, and n-hexane fractions of S. arvensis leaf extract and identifies the fraction containing the highest concentration. A descriptive observational method was employed. The leaves were extracted by maceration with 96% ethanol, followed by liquid–liquid fractionation using distilled water, ethyl acetate, and n-hexane. Flavonoids were qualitatively identified using Mg-HCl and FeCl₃ reagents, while total flavonoid content was quantified by UV–Vis spectrophotometry using quercetin as the reference standard at a maximum wavelength of 421 nm. Qualitative screening confirmed the presence of flavonoids in the crude extract and all fractions. The aqueous, ethyl acetate, and n-hexane fractions contained 17.111 mg quercetin equivalents per gram (mg QE/g; 1.7111%), 91.887 mg QE/g (9.1887%), and 7.9333 mg QE/g (0.7933%), respectively. The ethyl acetate fraction therefore exhibited the highest total flavonoid content, followed by the aqueous and n-hexane fractions. These findings demonstrate that solvent polarity influences the distribution of flavonoids during fractionation and identify ethyl acetate as the most effective of the examined solvents for obtaining a flavonoid-enriched fraction of S. arvensis leaf extract. The study provides a practical basis for selecting an appropriate fraction for subsequent phytochemical and pharmacological investigation.

Abstract

Tempuyung (Sonchus arvensis L.) leaves are traditionally used by communities in South Kalimantan to treat gout and promote external wound healing. The leaves contain secondary metabolites, including alkaloids associated with pharmacological activities such as antibacterial effects. This study determines the total alkaloid content of different solvent fractions of S. arvensis leaf extract and identifies the fraction with the highest content. A descriptive observational study was conducted from December 2023 to July 2024 using leaves collected from Sungai Batung Village, Juai District, Balangan Regency, South Kalimantan, Indonesia. The plant material was extracted by maceration with 96% ethanol and subsequently fractionated using n-hexane, chloroform, and methanol. Alkaloids were qualitatively identified using Wagner’s and Dragendorff’s reagents, while total alkaloid content was quantified by UV–Vis spectrophotometry using caffeine as the reference standard at 289 nm. All three fractions tested positive for alkaloids. The total alkaloid contents of the n-hexane, chloroform, and methanol fractions were 4.821%, 7.867%, and 10.11%, respectively. The methanol fraction therefore contained the highest total alkaloid concentration. These findings demonstrate solvent-dependent differences in the distribution of alkaloids across S. arvensis leaf extract fractions and identify the methanol fraction as the most promising fraction for further alkaloid isolation. The study provides a scientific basis for subsequent pharmacognostic, phytochemical, and pharmaceutical investigations of this medicinal plant.
