Abstract

Buffer solution content in Chemistry textbooks plays a significant role in achieving these educational objectives. This study aims to analyze buffer solution material in class XI Chemistry textbooks using the 4S TMD selection criteria, focusing on curriculum consistency, concept accuracy, and value education. A qualitative evaluative approach was employed, comparing the data collected from two textbooks (Book A and Book B) against established standards. The evaluation covered the scope and depth of the material, the accuracy of concepts, and the integration of values. The analysis found that both textbooks included six relevant concept labels, though Book B contained one overly general label. Regarding concept depth, Book A had two concepts with insufficient depth, while Book B had one overly shallow concept and one excessively detailed. Both books achieved the standard for concept accuracy. For value education, Book A integrated six core values, such as discipline and responsibility, while Book B incorporated eleven values, including creativity, democracy, and honesty. The findings suggest that Book A aligns more closely with the 4S TMD evaluation criteria than Book B. This highlights the importance of balancing curriculum alignment, conceptual depth, and value integration in educational materials.

Abstract

This study aims to determine whether there is an influence of the problem based learning model on the chemistry learning outcomes of SMA Negeri 1 Tanjung Batu. The research method was using a quasi-experimental design with non-equivalent control group design. The sample used was students of class XI MIPA 1 as the experimental class and class XI MIPA 2 as the control class. From the research results obtained, the average prates value in the experimental class is 29.39 and the average pascates is 68.18. While the average prates in the control class is 22.35 and the pascates average is 54.70. The results of the hypothesis test analysis using the t test at a significance level of 5%, obtained t (count) > t (table), that is (2.988)> (1.997). Thus H0 is rejected, meaning that there is an influence of the problem based learning  model on the chemistry learning outcomes of the salt hydrolysis material of students in eleventh grade of SMA Negeri 1 Tanjung Batu. It is recommended for teachers to be able to use the problem based learning model as an alternative learning model in an effort to improve student learning outcomes and activeness.

Abstract

Handbody lotion was formulated using guava leaf extract (Psidium guajava L.) and virgin coconut oil (VCO) as the main ingredients. The guava leaf extract was obtained through a maceration process using 96% ethanol as the solvent, resulting in a yield of 8.2%, while the VCO was produced enzymatically with a yield of 25.17%. The lotion was developed in three formula variations: F1 (5% extract, 10% VCO), F2 (6% extract, 15% VCO), and F3 (7% extract, 20% VCO). Physical characteristics were evaluated by assessing homogeneity, pH level, spreadability, viscosity, and specific gravity. The results indicated that all formulations met the quality standards in accordance with SNI 16-4399-1996. Based on the hedonic test, formula F1 was the most preferred in terms of texture, fragrance, and color.

Abstract

Salah satu tantangan yang sering dihadapi oleh guru kimia adalah minimnya ketersediaan sarana dan prasarana untuk menunjang pelaksanaan praktikum di laboratorium. Pada program studi pendidikan kimia Universitas Sriwijaya telah dilaksanakan beberapa riset/penelitian yang berkaitan dengan inovasi alat praktikum kimia. Salah satunya yaitu penelitian “Pengembangan Alat Elektroforesis Koloid Melalui Modifikasi Sumber Arus Listrik”. Oleh karena itu perlu dilakukan penyuluhan mengenai alat praktikum inovatif yang telah dikembangkan melalui riset/penelitian tersebut.  Kegiatan pengabdian ini dilakukan dalam tiga tahapan: penyampaian materi, praktik langsung, dan evaluasi. Tahap persiapan mencakup koordinasi antara pengabdian dan pihak terkait. Pada tahap pelaksanaan, materi disampaikan melalui presentasi, diikuti dengan praktik penggunaan alat elektroforesis koloid oleh peserta. Dari kegiatan pengabdian dapat disimpulkan bahwa khalayak sasaran pada mulanya terkendala melakukan praktikum dikarenakan kurangnya fasilitas. Dengan diperkenalkan dan dipraktikkan penggunaan alat praktikum inovatif, khalayak sasaran menjadi berminat dan membuat ide untuk mengembangkan alat praktikum inovatif lainnya yang sesuai dengan materi SMA. Alat praktikum inovatif ini mudah digunakan oleh guru dan dapat membuat pembelajaran menjadi lebih menyenangkan.

Abstract

Team-based learning is learning that is imposed on students to improve students' critical thinking, problem solving, solution finding, and communication skills. This learning is also useful for lecturers as teaching staff to improve higher abilities and skills. Researchers will combine practicum instructions with a team-based learning model. Team-based project practicum instructions will be able to make students together do practicum utilizing the surrounding environment to produce practicum products. This research is a research development with ADDIE development model and Tessmer formative evaluation. The research stages consist of self evaluation, expert reviews, one to one, small group. The innovation and originality of this research is the valid and practical team-based project practicum instructions used in Biochemistry practicum lectures. The results of the research were tested and used in Biochemistry team-based project practicum lectures. The results of laboratory development validation show the Aiken coefficient of 0.86 for material experts and 0.90 for design experts. The results of the implementation show the practicality of 96.45%. It can be concluded that the biochemistry lab instructions on team based project developed in the Biochemistry practicum is valid and practical.

Abstract

This development research aims to develop LKM green chemistry physics chemistry practical worksheet based on case method as supplementary teaching materials for students of the Chemical Education study program at Sriwijaya University using the 4STMD (Four Step Teaching Materials Development) method. The steps of the 4STMD method, namely the first stage is the selection stage, carried out by analyzing needs, curriculum and analyzing the material by looking for references in various sources. The second stage, namely the structuring stage, is carried out by adding or subtracting material and compiling the material. The third stage is the characterization stage, carried out by developing the results of material analysis. The fourth stage is the didactic reduction stage, but the researcher did not carry out the didactic reduction stage. Data collection techniques used in the form of interviews, pre-research questionnaires and validation questionnaires. In the material validation test, the validity of teaching materials was obtained based on the Aiken coefficient of 0.75 which was categorized as high. Based on these results, it shows that the development of LKM Green Chemistry Physics Chemistry Practical Worksheet Based on Case Method has met the valid criteria.
