Abstract

Dependence on social media among students has become a phenomenon that negatively impacts their critical thinking abilities, including difficulties in analyzing information, evaluating sources, and drawing logical conclusions. This study aims to examine contextual learning strategies as an effort to overcome the decline in critical thinking skills caused by social media dependence. The method used is a library research approach by reviewing various scientific sources such as books, journals, and previous studies relevant to contextual learning and critical thinking. The results of the study indicate that contextual learning can improve students’ critical thinking skills by linking learning materials to real-life situations, using authentic problems, and encouraging active student involvement in the learning process. This strategy promotes students to become more reflective, analytical, and independent in responding to information, including content obtained from social media. In addition, contextual learning helps students develop the ability to filter information and build deeper understanding. The implication of this study suggests that the consistent implementation of contextual learning strategies can serve as an effective solution to enhance students’ critical thinking skills and reduce the negative effects of social media dependence in the learning process.

Abstract

Belimbing wuluh (Averrhoa bilimbi L.) is a medicinal plant known to contain various secondary metabolites, particularly flavonoids, which possess potential biological activities. This study aimed to isolate flavonoid compounds from the ethanol extract of belimbing wuluh fruit and determine the total flavonoid content. The research was conducted through sample preparation, ethanol extraction by maceration, solvent evaporation, liquid-liquid fractionation using n-hexane, ethyl acetate, and water, followed by phytochemical separation using column chromatography, preparative thin-layer chromatography, and two-dimensional thin-layer chromatography. The isolated fraction was further analyzed, and the total flavonoid content was determined using UV-Visible spectrophotometry with quercetin as the reference standard. The extraction process produced an extract yield of 22.70%, while solvent evaporation resulted in a concentrated extract with a yield of 8.8%. Fractionation indicated that the polar fraction was obtained in the highest proportion. Column chromatography generated 50 fractions with different color characteristics, indicating successful separation of compounds based on polarity. Thin-layer chromatography showed an Rf value of 0.4 in the ethyl acetate mobile phase, while preparative and two-dimensional thin-layer chromatography produced a single dominant band, suggesting a relatively pure isolate. The UV-Visible analysis showed excellent linearity and revealed a total flavonoid content of 230.76 mg QE/g or 23.08%, exceeding the minimum quality standard. These findings demonstrate that belimbing wuluh fruit is a promising natural source of flavonoids and has potential for further pharmaceutical and phytochemical development.
