Abstract

Energy security is a strategic element in supporting sustainable development and national security, particularly in Indonesia's outermost islands. Wetar Island in Southwest Maluku Regency faces serious challenges in the form of high dependence on fuel oil and limited energy distribution systems. This study aims to conduct an in-depth analysis of the challenges of distribution and dependence on BBM and their impact on the energy security of Wetar Island. The study uses a qualitative approach with a case study method through analysis of policy documents, energy institution reports, and related scientific studies. The results of the study show that the dominance of BBM, logistical obstacles due to geographical conditions, and high energy costs have led to low resilience in the local energy system. In addition, the limited use of renewable energy has increased the region's energy vulnerability. This study emphasises the need for energy diversification, strengthening of local infrastructure, and integration of central and regional policies in order to achieve sustainable energy security for Wetar Island.

Abstract

Cultivating critical thinking skills in colloidal subjects is difficult due to the intricacy of abstract concepts, even though they are pertinent to daily life. This study seeks to evaluate the efficacy of the Predict-Observe-Explain (POE) learning model in improving high school students' critical thinking skills in colloid science. This pre-experimental study employed a one-group pretest-posttest design with 36 11th-grade science students chosen via purposive sampling. The research instrument comprised an essay test formulated according to Facione’s critical thinking indicators. The findings demonstrated a substantial enhancement in students’ average scores, rising from 32.55 to 75.14, accompanied by a Normalized Gain (N-gain) of 0.635 (moderate). An analysis based on indicators showed that the POE model was best at helping students improve their deduction and inference skills, but it still needed work on helping them figure out how trustworthy information sources are. This study concludes that the POE model is effective in enhancing scientific argumentation; however, it necessitates supplementary scaffolding to fortify students' metacognitive skills in the validation of external information.

Abstract

Interest in learning is one of the crucial elements in science learning. Based on interviews conducted by researchers, students' interest in learning is still relatively low because the learning media used are less interesting and boring and the learning methods used tend to be monotonous. One solution that can be taken to foster interest in learning is by developing Adobe Animate-based learning media. The purpose of this study is to analyze the level of product validity and the level of readability test of Adobe Animate-based learning media with the theme of food around me in fostering learning interest in junior high school/Islamic junior high school students. The research method used is Research and Development (R&D) according to Borg and Gall which is modified according to the needs of researchers which is limited to the design validation stage until product revision. The instruments used are assessment sheets for media experts, material experts and practitioners as well as readability test sheets. The study was conducted in 2 junior high schools and 1 Islamic junior high school in Cilegon City. Data were analyzed quantitatively and qualitatively. The validation results showed that this learning media obtained a score of 90.45% with a "very valid" category. The results of the readability test were 95.73% in the "very good" category. This shows that the Adobe Animate-based learning media with the theme of food around me is considered very valid for fostering the learning interest of junior high school/Islamic junior high school students.

Abstract

Indonesia's forests play a strategic role in maintaining ecosystem balance, but increasing deforestation and land degradation have increased the risk of environmental disasters, particularly flooding in Sumatra. As scientific attention has increased, research on Indonesian forests has grown rapidly but remains multidisciplinary and fragmented. This study aims to map the knowledge structure, thematic dynamics, and patterns of global collaboration in deforestation and disaster research in Indonesia, and to examine the integration of digital transformation into these studies. This study uses a descriptive quantitative approach through bibliometric analysis of 175 Scopus-indexed journal articles extracted using the keyword "Indonesian forest." The analysis was conducted using VOSviewer to map keyword co-occurrence and author collaboration by country, and to interpret the role of digital technologies such as Geographic Information Systems (GIS), remote sensing, and spatial analysis. The analysis shows that deforestation and forest fires are dominant themes closely related to disaster risk, air pollution, and health impacts. Digital technologies, particularly remote sensing and GIS, have become key methodological components in forest cover monitoring, carbon emission analysis, and flood-prone area mapping in Sumatra. Indonesia occupies a central position in global collaboration networks, with strong involvement from countries with high technological capacity, although the use of predictive and early warning systems remains relatively limited. The novelty of this research lies in the integration of bibliometric analysis with disaster and digital transformation perspectives, linking the thematic structure of research, international collaboration patterns, and their implications for flood mitigation in Sumatra. These findings provide important contributions to the development of forestry research and policy, and the strengthening of digital transformation in forest management and disaster risk reduction in Indonesia.

Abstract

The implementation of science practicums in junior high schools should support meaningful learning. However, in reality, they are often considered merely a supplement to theory. This study aims to compare the perceptions of students and teachers regarding the meaningfulness of science practicums in junior high schools in Pontianak City. The research was conducted using a survey method with a closed-ended questionnaire, the Meaningful Learning in the Laboratory Instrument (MLLI), which had been modified for use at the junior high school level. There were four indicators in accordance with the MLLI, namely motivation, critical thinking, procedural skills, and the benefits of practical work. Samples were randomly selected from 12 junior high schools that granted permission for the research. The results showed that students rated the meaningfulness of practical work at an average of 74% (in the high category), while teachers rated the meaningfulness of practical work at an average of 79% (in the very high category). The indicator of practical benefits received the highest score, while the indicators of critical thinking and skills were still low. These findings suggest that practical work has provided valuable learning experiences, but requires optimization through a more intensive inquiry and guidance approach to further develop students' critical thinking skills.
