Abstract

This study aims to determine the total flavonoid content in the ethanol extract of keji beling (Strobilanthes crispa) leaves using the UV-Vis spectrophotometric method with AlCl3 reagent. The research process includes maximum wavelength testing, preparation of quercetin standard solution, and analysis of total flavonoid levels. The results showed that the total flavonoid content in the extract was 144.347 ± 134.854 mg QE/g extract, with an extract yield of 0.4% and extract moisture content of 5.256%, which showed good potential in preventing the growth of microorganisms. Phytochemical screening revealed the presence of alkaloids, flavonoids, and tannins, while saponins, triterpenoids, and steroids were not detected. These findings confirm the importance of secondary metabolite compounds in plants and the potential of keji beling leaf extract as a source of active compounds with health benefits, including antioxidant and antibacterial activities. This study provides a basis for further research into the medical applications of this plant extract.

Abstract

Most Indonesian people still use traditional medicine because Indonesian medicinal plants can potentially be the main ingredient in medicine They contain various types of natural chemical compounds with diverse pharmacological and biodiversity effects. Several plants that usually grow around the yard and are easy to grow are beluntas (Pluchea indica (L.)). Beluntas are consumed as an additional ingredient when eating or processed as a herbal concoction. This study identified secondary metabolite compounds and total flavonoid levels in beluntas leaves. Beluntas leaves (Pluchea indica (L.)) were extracted using ethanol solvents and then tested using several reagents to identify their compound content. The total flavonoid test in the beluntas leaf extract was also conducted by adding a 10% aluminum chloride solution, sodium acetate, and aquadest to the extract sample, then incubated and measured for absorption using UV-Vis spectrophotometry in the wavelength range between 415-440 nm. This study demonstrates that beluntas leaves contain bioactive compounds including steroids, alkaloids, flavonoids, and tannins with a total flavonoid content recorded at 71.567±70.446 mg/g.

Abstract

Mulberry leaves (Morus alba Linn.) are a plant whose potential has been widely studied because it contains phytochemical compounds such as flavonoids and phenols which have various health benefits. This plant belongs to the Moraceae family and has the characteristics of a woody trunk, branches and brown bark with a height of between 5 and 10 meters, has oval or heart-shaped leaves with tapered tips, and has oval-shaped fruit that is black when ripe. This research aims to analyze chemical compounds in mulberry leaf extract (Morus alba L.) using spectrophotometric methods. Phytochemical screening showed positive results for flavonoids (Shinoda and NaOH test), alkaloids (Wagner and Dragendorff test), tannins (Braymer's solution and base) test, and steroids (Salkowski test). UV-Vis spectrophotometric analysis at a wavelength of 200-800 nm shows maximum absorption at 786 nm for the 10-2 dilution sample. Analysis of total flavonoid content using standard quercetin showed concentrations of 50.06 mg/g and 52.87 mg/g for the 1000 ppm and 500 ppm samples, respectively. The extract yield was 29.086%, with a water content of 4.415% and an ash content of 0.1%. These findings indicate that mulberry leaf extract contains various bioactive compounds with potential pharmacological properties, especially flavonoids which can be useful for medicinal applications.

Abstract

Student worksheets (LKPD) are assignment sheets that must be completed by students in learning which contain instructions, steps and basic competencies to be achieved. This research aims to measure the validity, practicality and effectiveness of Contextual Teaching and Learning-Based Participant Worksheets in Thematic Learning. The research model used is the development of a 4-D (Four D) model, consisting of 4 stages, namely; define, design, develop, and disseminate. The results of this research are in accordance with the assessment of 2 validator experts, namely that student worksheets with a percentage of 85% are categorized as valid, meaning that the LKPD developed is suitable for use. Apart from that, the results of practicality by expert LKPD practitioners with a percentage of 83% were categorized as practical. Furthermore, the effectiveness of the LKPD is said to be effective if it meets the cognitive, affective and psychomotor domains. It can be seen from the cognitive learning results reaching 93%, while the affective learning results are 3 students who are in the very good category with a percentage of 13%. There are 8 students who are in the good category with a percentage of 70. % there are 3 students who are in the quite good category with a percentage of 13%, there is 1 student who is in the need guidance category with a percentage of 4%. Judging from the psychomotor learning results, there are 11 students in the good category with a percentage of 75% and there are 4 students with a fairly good category with a percentage of 25%.
