Abstract

This study aims to determine the influence of brainstorming learning methods on the ability to think creatively in chemistry of grade XI science students. The type of research used is Quasi Experiment with a nonequivalent control group pretest-posttest design. The population of this study is all students of grade XI science for the 2022/2023 school year, totaling 158 students distributed in five classes. The sample used in this study was 60 students who were determined by cluster random sampling technique. Through random, class XI Science 4 was determined as a control class and in learning using conventional learning methods, namely lectures and discussions, and class XI Science 3 as an experimental class using brainstorming learning methods. Data on creative thinking skills were collected by test techniques using instruments in the form of description questions. The research hypothesis was tested using an independent t-test to analyze the difference between the n-gain of the control class and the experimental class using the help of SPSS 25 software. An independent t-hypothesis test yields a sig. (1-tailed) of 0.000 is less than the significance value (0.05). In the N-Gain test, experimental class N-Gain 0.6353 was obtained which was greater than that of control class 0.4255. Based on the t test and N-gain comparison, there is a positive and significant influence of brainstorming learning methods on students' creative thinking skills.

Abstract

This research aims to determine the effect of the problem-based learning model on the learning outcomes of reaction rate material in class XI students at SMAN 1 Lingsar. The type of research employed is a quasi-experiment, specifically a non-equivalent control group design. The population in this study consisted of all the students in class XI MIPA at SMAN 1 Lingsar, totaling 143 students divided into 4 classes. The sampling technique used is purposive sampling. The samples in this study were class XI MIPA 2 as the experimental class and XI MIPA 3 as the control class. The experimental class employs a problem-based learning model, while the control class utilizes a conventional learning model. The student learning outcomes were focused on the reaction rate material in the cognitive domain. The data analysis test used in this study is the t-test Gain. The gain in the experimental class (0.47) was greater than the gain in the control class (0.28). The analysis results showed that tcount (3.45) > ttable (2.03) at the 5% significance level, indicating a positive and significant effect of the problem-based learning model on the learning outcomes of reaction rate material for class XI students at SMAN 1 Lingsar.

Abstract

Sampah menjadi salah satu permasalahan dalam kehidupan manusia sekarang ini. Kurangnya kepedulian masyarakat akan keadaan lingkungan hidup dan juga kurang memahami cara mengolah sampah yang baik dan benar. Melimpahnya sampah plastik di lingkungan sekolah menjadi persoalan yang serius sehingga harus cepat untuk di selesaikan dan mencari solusi akan hal tersebut. Kretivitas pemanafaatan barang bekas menjadi kerajinan tangan adalah solusi yang cukup baik untuk saat ini agar dapat mengubah sampah botol plastik minum menjadi barang yang lebih berguna kembali, bahkan bisa memiliki nilai jual serta dapat di kreasikan menjadi barang yang mempunyai nilai estetika.

Abstract

This study aims to develop a three-tier diagnostic test instrument with minimally feasible criteria to identify the profile of understanding of the concept of buffer solution material in class XII MIPA students of State Senior High School (SMAN) 3 Mataram in the 2024/2025 academic year. The type of research used is research and development (R&D) with reference to the 4D (Define, Design, Develop, Disseminate) research model. The subjects of this study were 2 lecturers of chemistry education FKIP Unram and 2 chemistry teachers for the instrument validity test and class XII MIPA students of SMA Negeri 3 Mataram for the instrument practicality test. Data analysis techniques used include expert validity tests using Aikens'V analysis, empirical validity tests were analyzed using product-moment correlation techniques, reliability tests using Alpha Cronbach techniques, and practicality tests using percentage techniques. The three-tier diagnostic test instrument that has been developed meets the criteria of very feasible based on very valid expert validity with an Aikens'V value of 0.91, valid criteria based on empirical validity with a value range of 0.265 - 0.858, categorized as high based on reliability with a value of 0.7749, and very feasible based on practicality tests with a percentage value obtained of 81% - 100%. In the concept of buffer solution material, most students experienced misconceptions, namely 64.10% compared to students who understood the concept of 24.74%, 11.07% of students did not understand the concept, and 0.69% of students guessed.

Abstract

Proses pembelajaran merupakan proses komunikasi yang membutuhkan media yang bisa mewakili guru menyajikan informasi belajar kepada siswa sehingga pembelajaran kimia yang dianggap sulit dapat diatasi dengan adanya media yang telah banyak dikembangkan. Media pembelajran berupa majalah kimia dapat dijadikan sebagai sumber belajar alternatif dan dirasa lebih efektif dibandingkan modul cetak, buku dan bahan ajar lainnya. Survey di 3 lokasi sekolah, yakni SMAN 1 Labuapi Lobar, SMAN 2 Gerung, dan SMA Hang Tuah Mataram menunjukkan bahwa lebih dari 80% siswanya menyatakan suka dengan pelajaran kimia namu merasa kesulitan memahami pelajaran dan bahkan merasa bosan dengan penjelasan dari guru karena kurangnya media bacaan yang menarik dan menyenangkan. Solusi yang diberikan adalah mengenalkan kepada siswa media ChemMag, yakni suatu media pembelajaran kimia bebentuk majalah dengan konten konsep-konsep kimia pada proses pembuatan minyak kelapa. Pembuatan minyak kelapa adalah salah satu etnokimia lokal masyarakat Lombok yang sudah familiar bagi siswa setempat. Mengambil sampel di SMA 6 Mataram sebagai tempat untuk melaksanakan sosialisasi tentang media ChemMag seri ke-6 brtujuan untuk meningkatkan antusisme siswa dalam pembelajarn kimia. Hasil kegiatan sosialisais ini tergambar dari nilai respon siswa dan guru kimia di sekolah tersebut terhadap beberapa aspek penilaian. Aspek kemenarikan masuk kategori sangat praktis dengan persentase sebesar 81.62%; dari aspek kemudahan penggunaan masuk kategori sangat praktis dengan nilai persentase 84.31%; dari aspek isi masuk kaegori sangat praktis dengan nilai kepraktisan 83.23%; dari aspek manfaat tergolong sangat praktis dengan persentase sebesar 83.27%. Kesimpulan yang dapat diambil adalah: Siswa dan guru sangat tertarik dengan media majalah yang diperkenalkan; Respon siswa dan guru terhadap kegiatan sosialisasi media Chem Mag sangat bagus; Guru merasa tertarik untuk bekerjasama dengan tim pengabdian untuk mengembangkan media majalah pada tema yang lain di waktu yang akan datang.

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.
