Abstract

The West Papua Provincial Government in 2018 declared West Papua as a Province of Sustainable Development, which was reinforced by the enactment of Regional Regulation No. 10 of 2019.  In its development, West Papua Province was then divided into two provinces, namely West Papua and West Papua South. With the enactment of the second revision of the Special Autonomy Law No. 2 of 2021, the threat of regional division has grown, including the shrinking of productive agricultural land in food-producing areas.  The objectives of this study are to (1) examine the development of provincial conservation policies in West Papua; (2) explore the agenda for regional division accompanied by commitments to sustainable development in West Papua Province; and (3) analyze the production capacity of staple foods in West Papua Province.  This research is a case study in which West Papua Province was deliberately selected. A descriptive method with a desk study approach was used as the data analysis method. The results of the study concluded that (1) the current West Papua Conservation Province policy is not running as it should; (2) the policy of forming new autonomous regions (DOB) has caused each cultural entity to focus on expanding itself and neglecting the sustainable development commitments initiated since 2015; and (3) the production of staple food commodities, particularly rice, in West Papua has experienced a drastic decline over the past five years, threatening local food security.  West Papua is projected to face a rice deficit of 23.27 tons by 2025.

Abstract

Infections caused by Salmonella typhi remain a serious global health problem, particularly due to the increasing bacterial resistance to conventional antibiotics. Therefore, the search for effective natural antibacterial sources is urgently needed. Rhizophora apiculata, a mangrove plant known to contain various bioactive compounds, has the potential to be an alternative antibacterial source. This study aims to identify the phytochemical content in R. apiculata fruit extract and evaluate its antibacterial activity against S. typhi using the disc diffusion method and bacterial cell morphology analysis via SEM. The phytochemical screening results revealed that the extract contains phenolics, tannins, alkaloids, and flavonoids. However, saponins and steroids were not detected. The antibacterial activity test showed that the extract at a concentration of 250 mg/mL significantly (p < 0.05) inhibited the growth of S. typhi, with the largest inhibition zone (11.6 mm). SEM observations supported this finding by showing a decrease in the number of bacterial cells at extract concentrations of 125 mg/mL and 250 mg/mL, where the highest concentration caused the most bacterial cell death. This study demonstrates the potential of R. apiculata fruit extract as an effective natural antibacterial source for the development of alternative treatments for S. typhi infections

Abstract

This study aims to analyze the needs for developing an integrated instructional model to enhance elementary pre-service teachers’ mathematical problem-solving skills in geometry and measurement. A qualitative needs analysis was conducted through diagnostic tests, interviews, classroom observations, and document analysis involving pre-service teachers and educators. Findings reveal significant difficulties in understanding abstract concepts, low confidence in problem-solving, and minimal integration of science contexts in current mathematics instruction. Despite these challenges, participants expressed strong interest in interdisciplinary, context-based learning. The results highlight the potential of integrating video and mathematical modeling into Problem-Based Learning (PBL) to improve problem comprehension and engagement. Based on the data, the PBL-ViMo model—combining PBL, video-based problem orientation (Vi), and mathematical modeling (Mo)—was developed as a responsive and structured approach. Video facilitates visual understanding of real-world problems, while modeling provides a systematic framework for translating contexts into mathematical solutions. The study concludes that the PBL-ViMo model addresses identified learning gaps and offers an innovative, learner-centered strategy to strengthen both conceptual understanding and pedagogical competence in mathematics teacher education.

Abstract

This research was motivated by low student motivation and learning outcomes in the Culinary Basics course at SMKN 6 Padang. Conventional learning models such as lectures and PowerPoint presentations are considered incapable of generating student enthusiasm and engagement in practice-based learning. The purpose of this study was to determine the effectiveness of implementing the Project-Based Learning (PjBL) model combined with video media in improving student motivation and learning outcomes in this subject. This study used a quantitative approach with a quasi-experimental design using a pretest-posttest control group design. Data collection used two main instruments: a learning outcome test to measure cognitive and psychomotor aspects, and a learning motivation questionnaire to measure students' affective factors. These instruments were tested for validity and reliability before use. Data were collected from two classes: an experimental class using PjBL with video media and a control class using the lecture method with PowerPoint. The results of data analysis showed a significant difference between the experimental and control classes. Students learning using the video-assisted PjBL model showed greater improvements in learning motivation and learning outcomes. The significance value obtained from the statistical test was below 0.05, indicating that the use of the video-based PjBL model was proven effective in improving the quality of culinary practical learning in vocational schools. Therefore, the implementation of video-assisted PjBL can be an innovative and engaging alternative learning strategy in vocational schools.

Abstract

Learning that still relies on conventional methods, such as lectures and textbooks, often fails to facilitate understanding of complex concepts, especially in subjects like Natural and Social Sciences (IPAS), which require in-depth and contextual understanding. Learner-centered education should be enhanced through innovative learning media, including the use of AI-based Hypercontent E-Worksheets (E-LKPD) to assess learning effectiveness. This study aims to develop a valid, practical, and effective AI-based Hypercontent E-LKPD for IPAS (Social and Natural Sciences) learning in Grade V of elementary school. The research was conducted in Class V of SDN 10 Sekayu with 50 student participants. The study followed a Research and Development (R&D) approach using the Rowntree development model and Tessmer’s formative evaluation. Data were collected through interviews, questionnaires, expert reviews, one-to-one and small group evaluations, and pretest-posttest. The validity score of the developed E-LKPD was 4.62 (very good). Practicality scores were 4.6 (one-to-one) and 4.42 (small group), both considered very practical. Effectiveness was measured through learning outcomes, showing a pretest score of 42.50%, a posttest average of 84.75%, and an N-Gain of 0.72 (high category). These results indicate that the developed AI-based Hypercontent E-LKPD is valid, practical, effective, and highly suitable for use in IPAS learning for Grade V elementary students.
