Abstract

Dragon scale (Drymoglossum piloselloides) leaf is a plant that contains secondary metabolites with antioxidant potential. This plant is known for its easy to grow nature and has a wide habitat distribution. The extraction method using acetone solvent has been proven effective in extracting secondary metabolites from this plant. To improve the extraction efficiency, this study used an optimization approach using the Central Composite Design (CCD) method. CCD involves three main factors in extraction experiments, namely solvent concentration, extraction time, and extraction temperature. Experiments were conducted with variations of these factors to find the optimal extraction conditions. The results of CCD method showed that the solvent concentration of 70%, extraction temperature at 52°C, and extraction time of 60 minutes. Statistical analysis showed that the model used was significant, with an F-value of 9.20 and a P-value less than 0.01159, indicating that the factors tested had a significant effect on the extraction results. The results of this study have great potential in maximizing the use of dragon scale leaves as a source of antioxidant secondary metabolites.

Abstract

Clean water is a vital requirement for children at the primary school level as it supports their learning process. The availability of clean water not only facilitates learning activities but is also an important aspect in supporting a lifestyle that is responsible for natural resources, especially in the context of using renewable energy. The emphasis on an appropriate lifestyle in the utilisation of clean water became the focus of the community service conducted at SD Negeri 2 Rantau Pulut. Through this socialisation activity, students were given an understanding of the importance of a clean lifestyle that utilises clean water sources wisely, while integrating the use of renewable energy. The results of this service showed positive progress. Students' understanding of the importance of a clean lifestyle and the utilisation of clean water with renewable energy has increased significantly, reaching an understanding level of 91.67%. From this, it can be concluded that this socialisation successfully achieved its goal of raising students' awareness of the importance of clean water and a sustainable lifestyle.
