Abstract

This research is development research or Research and Development (R&D) which aims to produce Student Worksheets (LKPD) which are categorized as minimally feasible and practical. The research and development model used in this research is a 4D model which consists of four stages, namely defining, designing, developing and disseminating. In this research, the 4D model is limited to the development stage. Validation of the LKPD was carried out by two Chemistry Education lecturers and two Chemistry subject teachers at high school level. Data analysis in the expert validation test uses the Aiken's V Index formula. The validation results show that the LKPD validity index is generally 0.84 with a very valid validity category, which means the LKPD is very feasible based on validity. After the LKPD was tested for validation and revision, it was then tested for practicality on 25 students and 2 chemistry subject teachers. The test results show that the practical level of LKPD generally reaches 86% based on student responses and 95% based on teacher responses, both of which are classified as very practical. Based on this, this LKPD is declared very suitable for use as a learning medium regarding acid-base solutions at the high school level.

Abstract

Sumbawa oil is a traditional medicine renowned for its efficacy in treating various ailments. This oil continues to be produced today using a variety of spices. Most of the production residue comes from coconut milk curd (blondo). The caramelization process of blondo produces a sweet flavor. This residue is then processed into high-value snack products. Dodal is tested organoleptically to ensure the taste, color, and aroma of the spices in the product are pleasant to consume. This testing is conducted to ensure the quality of the dodal due to high-temperature heating. Dodal is packaged in ready-to-eat packaging, making it convenient for use and storage. This processing ensures that the oil residue (in the form of dodal) has a long shelf life for extended storage and adds economic value to the local community.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan keterampilan guru kimia SMA di Lombok Timur dalam mengintegrasikan nilai-nilai budaya lokal suku Sasambo (Sasak, Samawa, dan Mbojo) ke dalam praktikum kimia. Panduan praktikum memanfaatkan teknologi digital sehingga disajikan dalam E-Panduan. Kegiatan ini dilatarbelakangi oleh keterbatasan pengetahuan dan kompetensi guru dalam merancang praktikum berbasis budaya lokal dan minimnya panduan praktikum yang menggunakan kearifan lokal sebagai konteks pembelajaran. Adapun tahapan dalam pengabdian ini yaitu, tahapan persiapan (observasi, koordinasi dengan Tim MGMP Kimia Lombok Timur, penyusunan instrumen); tahapan pelaksanaan (sosialisasi, pelatihan, dan pendampingan penyusunan e-panduan praktikum); tahapan evaluasi (pretest dan postest). Hasil dari kegiatan pengabdian ini menunjukkan bahwa terdapat peningkatan yang signifikan pada empat aspek utama, yaitu pengetahuan guru mengenai etnokimia Sasambo, pengalaman penerapan etnokimia sasambo, penguasaan teknologi e-panduan praktikum berbasis etnokimia, serta sikap dan minat dalam mengembangkan e-panduan praktikum kimia terintegrasi etnokimia sasambo.

Abstract

Research and development were conducted with the aim of describing the chemistry concepts contained in the traditional gold mining culture in Prabu village, Middle Lombok and gold crafts in Sekarbela, Mataram. This research is a qualitative descriptive study with a survey approach, conducted in collaboration with 4D Research and Development. The data in this study were collected using the triangulation method, which included interviews, observations, and literature studies. The data analysis technique employed the Miles and Huberman method, which involved data reduction, data presentation, and drawing conclusions. The results of the study indicate that in the traditional gold mining culture in Prabu Village, Middle Lombok, and the gold craft cultural activities in Sekarbela Mataram, there are chemical concepts, including elemental chemistry, reaction equations, oxidation-reduction reactions, the application of the solubility product of salts to separate chemical components from their mixtures, the concept of acids and bases, and the concept of colloids. Teaching materials in the form of ethnochemistry magazines from research and development have a feasibility category that is very feasible, based on the magazine's size, cover design, and content design, with an average V coefficient of 0.94. The feasibility of ethnochemistry magazines, based on the material component indicator, with sub-indicators of material suitability and stimulating curiosity, as well as the feasibility of presentation, with sub-indicators of presentation techniques and presentation support, and the linguistic component indicator, is classified as very feasible, with an average V coefficient of 0.93. In general, ethnochemistry magazines from research and development are classified as very feasible, with an average V coefficient of all aspects of 0.935.

Abstract

Chemistry is a subject that students tend to dislike. Student learning outcomes are still low due to the lack of student interest in learning which is caused by the lack of media used for learning both at home and at school. To overcome this deficiency, interesting learning media is needed as a complement to learning resources that students can use anywhere and anytime, one of which is Android-based mobile learning media. The aim of this research is to determine the effectiveness of using Android-based mobile learning chemistry learning media to increase students' interest in learning chemistry on the topic of buffer solutions. This type of research is Quasi Experimental Design in the form of Nonequivalent Control Group Design. The subjects of this research were students of class XI MIPA 1 and XI MIPA 2 at SMAN 3 Mataram, totaling 58 students. Data collection techniques include interviews and questionnaires. The data analysis used was N-gain score analysis as well as normality, homogeneity and t-tests. The research results showed that the N-gain for the experimental class was 0.618 with medium criteria (effective) while the control class obtained 0.299 with low criteria (not effective). Normality and homogeneity tests showed that the N-gain data was normally and homogeneously distributed. The results of the t-test at the 5% significance level were obtained a significance value showing 0,000 < 0,05. These results indicate that the use of mobile learning media is effective in increasing students' interest in learning chemistry on the topic of buffer solutions.

Abstract

This study analyzes the learning loss of first-year students' chemistry concepts at FKIP, University of Mataram. The research sample was 112 first-year students taking introductory chemistry courses at FKIP University of Mataram, 14 male students (12.5%) and 98 female students (87.5%)—these students, as a whole, face two years of online learning in high school. The primary data in this study is the analysis of respondents' test results related to prior knowledge of chemistry concepts during one semester of lectures. The results showed that the idea of limiting reagents and percent composition showed the highest learning loss (53.57%), while the concept of moles and molar mass and matter showed the lowest learning loss percentage of 32.14%. Furthermore, the results of statistical tests show the relationship between the average score before the UTS implementation and after the UAS implementation. The previous lack of online learning to strengthen students' prior knowledge indicates the cause of learning loss in chemical concepts. Questionnaire analysis stated that education through WA groups, the duration of chemistry learning was low, and the lack of feedback given by teachers on assignments students were working on during the learning process strengthened the current conditions.
