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

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.

Abstract

The purpose of this study is to determine the effect of the Socio-Scientific Issue (SSI) teaching approach on the chemical science literacy skills of students at MA NW Kembang Kerang. The indicators of science literacy skills measured include the ability to explain scientific phenomena, identify scientific problems, and use evidence in a scientific manner. This research utilizes a Quasi-Experiment design with a pre-test and post-test control group design, conducted in class XI at MA NW Kembang Kerang, involving 41 students. The control class (XI MIPA 1) was taught conventionally, while the experimental class (XI MIPA 2) used the Socio-Scientific Issue teaching approach. Data on chemical science literacy were collected using a test instrument administered before and after the teaching process. The data were analyzed using the N-Gain test and used to draw conclusions. The results of the study show that the SSI teaching approach has an effect on students' chemical science literacy, based on the t-test results where thitung > ttabel. The increase in chemical science literacy in the experimental class is categorized as moderate (N-Gain = 0.60), while the control class is in the low category (N-Gain = 0.28). It is expected that these results can assist both teachers and students in chemistry learning that connects school learning with contextual issues in daily life.

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 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

The purpose of this research was to determine the level of independence learning, chemical learning outcomes and the correlation between independence learning and chemical learning outcomes during the Covid-19 period in class XI MIPA SMAN 6 Mataram in 2020/2021. This type of research is called correlational research. The population used was all students from class XI MIPA SMAN 6 Mataram in 2020/2021, which consisted of 4 classes totaling 126 students and the sample used was 56 students using the Slovin formula. The sampling technique is proportional random sampling. Data in the form of the level of independence learning were collected using a questionnaire distribution technique, while the learning outcomes data were collected using a documentation technique from the value of chemistry test result. The data analysis technique used is non-parametric statistics using contingency correlation coefficient test. The results showed that the level of independence learning and chemical learning outcomes were categorized as moderate. The results also show a contingency correlation coefficient (C) which is 0.612 and compared to a rtable of 0.266 which shows there is a positive and significant relationship between independence learning and chemical learning outcomes during the Covid-19 period in class XI MIPA SMAN 6 Mataram Years 2020/2021
