Abstract

Toona sinensis (Surian) is a species of the Toona genus of the Meliaceae family that is highly resistant to cold weather compared to other Meliaceae families. T. sinensis is widely used as a traditional medicine such as a worm medicine, dysentery, expectorant, as a tonic and can also be used to lower blood sugar and for the treatment of syphilis and many other benefits. Based on previous research, it is known that the content of secondary metabolites found in the surian plant includes limonoids, phytol, flavonoids, essential oils, phenol triterpenoids, and catechins. This study was conducted to obtain T. sinensis leaf extract through a maceration process using ethanol solvent, and phytochemical tests to determine the content of secondary metabolites in it. The extraction results obtained in the form of a dark green isolate, with a mass of 24.82 grams and a yield of 17.98%. Phytochemical testing showed that the ethanol extract of Surian leaves contains secondary metabolite compounds such as alkaloids, steroids, phenolics, and quinones.

Abstract

Chemistry is one of the elective subjects at the secondary education level that some students find difficult because it involves abstract concepts and is full of symbols. This condition necessitates learning innovation that offers a fun chemistry learning experience for students. This community service activity, conducted by the Chemistry Department, Faculty of Mathematics and Natural Sciences, Mulawarman University, aimed to introduce 11th-grade students at SMA Negeri 1 Kota Bangun to a fun chemistry learning method using the Chemistry Detective Kit. This kit was developed as a learning media innovation using a case-solving approach, where students were invited to analyze cases through a series of simple chemistry experiments, mimicking the work of a detective. The activity included group practical work, followed by a discussion of the chemistry concepts underlying each experiment. The results of the activity's evaluation through questionnaires and interviews indicated that participants responded very positively to the activity, both in terms of the materials and the activity's execution, and in its improvement in students' understanding of chemistry. The majority of students felt that each chemistry detective case provided a fun learning experience (71.9% Strongly Agree, 25.0% Agree). The evaluation results also showed that the learning activities in the form of investigative games helped students understand chemistry concepts and motivated them to learn more about chemistry.
