Abstract

Effective biology learning requires various components to enhance learning, including implementing appropriate learning models and media. This study examines the effect of the SrVER learning model assisted by augmented reality (AR) media on the biology learning outcomes of 10th-grade students at SMAN 2 Mataram. This research employs a quantitative approach using a quasi-experimental method with a non-equivalent control group design. The study population consists of 13 10th-grade classes at SMAN 2 Mataram, from which four classes were selected as the research sample using purposive sampling. Data was collected through questionnaires and student learning outcome tests. The data analysis techniques used in this study include the N-Gain statistical test and the Mann-Whitney test. The results show that the experimental class achieved an N-Gain score of 0.4 (moderate), while the control class obtained an N-Gain score of 0.2 (low). Furthermore, the Mann-Whitney test yielded an Asymp. Sig (2-tailed) value of 0.001, which is less than 0.05, indicating a significant difference between the post-test scores of the control and experimental classes. These findings confirm that implementing the SrVER learning model assisted by augmented reality media can significantly improve the biology learning outcomes of 10th-grade students.

Abstract

Mangrove forests play an important role in protecting the coast from abrasion, providing habitat for marine life, and sequestering carbon. However, mangroves are threatened by land conversion, unsustainable activities, and lack of public awareness. This program aims to build a generation that cares about the environment and encourages active community involvement in coastal conservation. This approach is expected to create a generation that not only has environmental knowledge, but also has the care and skills to contribute to conservation efforts. The program began with field observations and interviews to collect data on the geographical conditions and understanding of the local community regarding mangrove ecosystems. The results of observations were used to design teaching media in the form of mangrove species identification books, books about mangrove ecosystems, animal association books in mangroves, and educational games about food chains in mangroves. Based on the results of the activities, this study shows that the use of teaching media in the form of mangrove food chain posters, pictures of mangrove ecosystem fauna, and books about mangrove species is effective in increasing children's knowledge about mangrove ecosystems.

The aim of this research is to determine kind of solvent which achieve better result. The method used is laboratory experiments for phytochemical screening and antioxidant activity assay. This research consists of 2 (two) stages. First stage aims to obtain extract of suji by using certain solvent, and the second stage is carried out to examine  secondary metabolite compounds of the extract using phytochemical screening and then to determine the antioxidant activity of extract using the DPPH method. This research used  2 kinds of solvent, ethanol plus ethyl acetate in the first sample, and the second one by ethanol only. Sample which extracted by ethanol plus ethyl acetate positively contains terpenoids, whereas flavonoid and  alkaloids are detected in a significant number. The DPPH test results obtained the equation y = 0.3492x + 12,059, indicating that the antioxidant activity of suji which extracted by ethanol plus ethyl acetate is classified as moderate as the IC50 value of the extract of suji is108,65 ppm. The other sample which extracted just by ethanol also contains terpenoid, flavonoid, and alkaloid, but in a greater number. In the second sample also detected steroid compound which undetectable in the first sample. DPPH score in the second sample which extracted  by ethanol. is y= 06352x + 18, 786. By using this equation we found 49.14 ppm as IC50 score. This score is classified as strong activity. This result shows that antioxidant activity of the second extract is stronger than the first one. The result also meaning that ethanol is more effective in extracting phytochemical compounds of suji than ethanol plus ethyl acetate.
