Abstract

This research aims to develop interactive multimedia based on Problem Based Learning that can be installed on Android, and test the effectiveness of its use on the ability to analyse students' ecosystem material. This research is a type of Research and Development, this research was conducted at one of the Bogor Regency State High Schools with the research sample, namely IPA 6 class as the experimental class. The novelty of this research lies in the development of interactive multimedia based on Problem-Based Learning (PBL) specifically designed for ecosystem material to improve the analytical skills of senior high school students, which has not been extensively explored in the context of science education. This development research procedure uses the (4D) model consisting of 4 stages, namely Define, Design, Develop, and Disseminate. The field trial implementation used a one group pretest-postest research design. The techniques used were tests (pre-test and post-test), checklist questionnaire sheets, and documentation. The assessment results show that interactive multimedia gets a very feasible category. This is based on the average percentage of assessment from the expert validation team which is 87%. Interactive multimedia based on Problem Based Learning on android is proven to be effective in improving the ability to analyse students, with an N-gain value of 68.02 included in the medium category. This shows that interactive multimedia based on Problem Based Learning can improve students' analytical skills.

Abstract

The potential of Palu local shallot roots as an antifungal agent has not been optimally utilized. The aim of this research is to determine the effectiveness of Palu local shallot root extract against the fungus Candida albicans, identify the optimal concentration for inhibiting the growth of Candida albicans, and to use the findings as an educational medium. This research employed a laboratory experimental method with a completely randomized design (CRD) consisting of 5 treatments and 4 replications at concentrations of 0% as a negative control, 25%, 50%, 75%, and 100%. The Candida albicans fungus was obtained from Paramartha Lab Mojokerto with strain code ATCC-14053. The parameter observed was the diameter of the inhibition zone formed. The data were analyzed using Analysis of Variance (ANOVA), followed by a Least Significant Difference (LSD) test. The results of this study showed that the extract of Palu local shallot roots effectively inhibited the growth of Candida albicans* at a concentration of 100%. This research is feasible to be used as an educational medium in the form of a digital flipbook with an eligibility percentage of 87.08%.

Abstract

This research aims to identify the learning difficulties of 8th-grade students in Science (Biology) at SMP Negeri 19 Palu. This type of research is descriptive. The subjects in this research were all students of classes VIII A and VIII B, consisting of 46 students. The data collection technique used was a questionnaire on factors influencing students' learning difficulties. The results of the study showed that the average internal difficulty factor for the "agree" response was 27%, while "disagree" was 73%. For the external difficulty factor, the "agree" response was 31%, while "disagree" was 69%. These results indicate that students' learning difficulties are classified as high in both internal and external factors. Therefore, it can be concluded that both external and internal factors significantly contribute to the high level of learning difficulties in the Science subject at SMP Negeri 19 Palu.

Abstract

The nature of Natural Science as a science that originates from nature and has several abstract concepts that cannot be presented directly into the classroom is a challenge for teachers to convey these concepts. The rapid development of technology allows humans to interact directly without being limited by space and time. One technology that can be used to visualize several abstract concepts in science lessons is augmented reality. This study aims to develop science teaching materials based on Augmented Reality (AR) on the material of energy in life systems. This type of research is development research referring to the development of Borg & Gall which was modified from (Sugiyono, 2014). This study consists of 10 stages, namely (1) Potential and Problems; (2) Data Collection; (3) Product Design; (4) Product Design Validation; (5) Product Design Revision; (6) Product Trial; (7) Product Revision; (8) Usage Trial; (9) Product Revision; and (10) Mass Production. By implementing all these stages, it is expected to produce science teaching materials based on Augmented Reality that are valid and reliable based on expert responses and trial results. The output of this study is a research article published in an accredited national journal and HAKI science teaching materials based on Augmented Reality.

Abstract

This researcher aims to develop handouts based on Contextual Teaching and Learning (CTL) to increase motivation and learning outcomes for Class VII students at SMP Negeri 7 Lubuklinggau. The method used is Research and Development (R&D) with a 4D development model but its application only reaches the 3D stage, namely: definition stage, design stage, development stage. The research sample or research subjects were students in class VII-2 of SMP Negeri 7 Lubuklinggau. The data collection technique uses a validation sheet. Based on validator analysis, it shows that the quality of learning media meets the very valid criteria with (1) 28 media validation results with a range of 25.2 < X ≤ 30, 21 language validation results with a range of 17.38, (2) increasing motivation 36.16 and 42.96 and (3) learning outcomes 0.58. So it can be said that the Contextual Teaching and Learning (CTL) based handouts were developed and validated as innovative teaching materials that can increase motivation and can be used in learning, with validation categories of good media expert, very good language expert, and very good material expert. Meanwhile, learning motivation shows a good category with an average N-gain of learning outcomes in the High category.

Abstract

The study of incorporating computational thinking (CT) into science, technology, engineering, and mathematics (STEM) education has gained interest. We carried out a semi-systematic review of 50 empirical papers on this topic. Our findings highlighted the following crucial points: (a) the majority of research utilized domain-general descriptions for CT, while a few studies suggested domain-specific terms that addressed STEM education; (b) problem-based instruction developed as the most common teaching approach, with popular contextual topics including game design, robotics, and computational modelling; (c) assessments of student learning in combined CT and STEM varied in objectives and formats, with approximately one-third evaluating both CT and STEM integration. Based on our findings, we make recommendations for future study and implementation, with an emphasis on defining and evaluating CT in STEM contexts, developing successful instructional strategies for incorporating CT into STEM, and investigating approaches to promote inclusiveness in integrated CT and STEM education.
