Abstract

This study aims to determine the level of validity of the content and suitability of augmented reality (AR)-based learning media developed using the Assemblr Edu application for molecular structure material. This study employs the Design-Based Research (DBR) method with the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model, modified up to the development stage. Data collection techniques include interviews, validity questionnaires, and media feasibility questionnaires. Data validity analysis uses Aiken’s V formula, while media feasibility is measured using a percentage formula. The learning media product was tested on 28 eleventh-grade students at SMAN 1 Wanasaba. The validity test results showed that the media was highly valid with an Aiken’s V value of 0.92. The feasibility test results showed that the media was highly feasible with a percentage of 86.86%. This media is deemed valid and suitable for use as an innovative learning alternative to enhance students' understanding of molecular structure concepts. This study demonstrates that integrating AR technology into learning can serve as a strategic tool for optimizing the visualization of abstract concepts in a contextual, engaging, and relevant manner aligned with 21st-century needs.

Abstract

This study aims to determine the effect of POE (Predict, Observe, Explain) learning model on chemical learning outcomes of acid-base material in class XI IPA SMAN 1 Langgudu. This type of research is a quasi experimental design. The population is all students of class XI IPA SMAN 1 Langgudu which amounted to 50 people. The sampling technique used saturated sampling. Determination of control and experimental classes is based on the average value of the midterm assessment, students of class XI IPA 1 obtained a greater average value of 78.76 than class XI IPA 2 which is 70.16 so that class XI IPA 1 is designated as the control class and XI IPA 2 as the experimental class. Data collection techniques using test instruments. The average value of the experimental class pretests (49.12) was lower than the control class (52.28). While the average value of the experimental class posttest (84.4) is higher than the control class (76.92). The N-Gain test results show that the increase in learning outcomes of experimental class students is more in the high category than the control class. The t-test results obtained tcount of 2.4091> ttable 2.0106 then H0 is rejected and Ha is accepted. While the results of the percentage of student activeness of the experimental class at each meeting were higher than the control class, so that experimental class students were more active than the control class. The results of this study can be concluded that the POE learning model (Predict, Observe, Explain, and Explain) is an effective learning model.

Abstract

This study aims to examine the effect of the cooperative learning model Talking Stick on students’ learning outcomes in the colloid topic among Grade XI students at MA NWDI Wakan. A quasi-experimental method with a pretest–posttest control group design was employed. The sample consisted of 40 students from classes XI MIPA 1 and XI MIPA 2. Data were analyzed using N-Gain analysis, normality testing, homogeneity testing (F-test), and hypothesis testing with an independent t-test. The hypothesis testing at a significance level of α = 0.05 yielded a t-value of 3.972, which exceeded the t-table value of 2.024, indicating a significant difference between the experimental and control groups. These findings demonstrate that the implementation of the Talking Stick cooperative learning model has a positive effect on students’ learning outcomes in the colloid topic.

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

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman guru MGMP Kimia Lombok Timur terhadap profil, akreditasi, prestasi, serta prospek karier lulusan Program Studi Pendidikan Kimia FKIP Universitas Mataram sebagai dasar dalam memberikan arahan studi lanjut kepada siswa. Latar belakang kegiatan ini adalah masih terbatasnya informasi yang dimiliki guru sekolah mitra mengenai capaian program studi dan keragaman jalur karier alumni pendidikan kimia. Metode pelaksanaan meliputi sosialisasi profil program studi, orientasi karier lulusan pendidikan kimia, diskusi interaktif, serta evaluasi melalui angket respon guru. Kegiatan dilaksanakan secara luring dengan melibatkan 22 guru MGMP Kimia Lombok Timur. Hasil kegiatan menunjukkan bahwa 76% guru baru mengetahui akreditasi unggul Program Studi Pendidikan Kimia FKIP UNRAM, 82% guru menyatakan bersedia merekomendasikan siswa untuk melanjutkan studi ke program studi tersebut, dan 70% guru menyatakan masih membutuhkan referensi tambahan terkait peluang karier kimia di luar profesi guru. Temuan ini mengindikasikan peningkatan pemahaman dan persepsi positif guru terhadap pendidikan kimia sebagai bidang studi dengan prospek karier yang luas. Luaran kegiatan berupa penguatan jejaring kemitraan antara universitas dan MGMP, peningkatan literasi karier sains guru, serta data persepsi mitra yang bermanfaat bagi pengembangan strategi promosi program studi.
