Abstract

The Indonesian Ministry of Education and Culture changed the curriculum from the 2013 curriculum to the Independent Learning Curriculum. The term "independent learning" refers to a policy prepared by the government to improve the quality of education, which will ultimately create superior students and university students who are ready to face the very complex challenges of the future. The purpose of this study is to determine the effect of using interactive animated video media on the learning outcomes of fifth grade students at SDN Tambakrigadung II Lamongan. The method used was a quasi-experimental design. This research type is quantitative, and the design used in this study is a Nonequivalent Control Group Design. This study was conducted in the even semester. The sample in this study were fifth-grade students of SDN Tambakrigadung II Lamongan. Data collection techniques used were tests (pretest and posttest) and documentation. The results of this study showed that the average (mean) posttest score of students in the experimental class was 85.50 with a standard deviation of 1.850, while in the control class the average was 77.20 with a standard deviation of 2.142. This difference in averages indicates that students in the experimental class who used interactive animated video media achieved higher learning outcomes than students in the control class who did not use such media.

Abstract

Forest and peatland fires are significant environmental issues in Central Kalimantan, particularly in Basarang Village, Kapuas Regency. This study aims to analyze community perceptions and knowledge regarding forest and peatland fires to support more effective prevention efforts. A quantitative approach was used, employing survey techniques through questionnaires administered to 30 respondents. The results indicate that the level of public perception is categorized as moderate, with an average score of 65.8%, and the level of knowledge is also moderate, with an average score of 75.0%. The community generally understands the definition, impacts, and regulations related to land fires; however, a gap remains between knowledge and actual practice in the field, such as participation in outreach programs and reporting fire incidents. It was also found that although residents are aware of the dangers of land clearing by burning, some still practice it due to economic constraints and traditional habits. This study recommends enhancing outreach efforts, providing contextual education, and offering tangible government support to strengthen community involvement in sustainable forest and peatland fire prevention.

Abstract

This research is motivated by the low independence of elementary school students in mathematics, especially fractions, due to conventional methods and the lack of innovative teaching materials. The objective is to develop and test the effectiveness of Applied Behavior Analysis (ABA)-based mathematics teaching materials to improve student independence. Using the ADDIE development model, this research began with an analysis of student needs and the curriculum. The design stage included designing a fraction addition module, including visual elements. Development involved validation by material and media experts, as well as revisions. Implementation was carried out through a trial in grade V of SD Negeri 1 Moyot, with data from response questionnaires and learning outcome tests. Product evaluation showed that this teaching material was very feasible (media experts 98%, material experts 80%). Student responses were positive ("Good" 66.48%), and learning outcomes improved ("Good" 75.64%), with classical completeness of 76%. The implication is that ABA teaching materials are effective in improving student independence and mathematics learning outcomes, and serve as a reference for the development of innovative teaching materials

Abstract

Solar cells are devices composed of solar panels that convert light into electrical energy. Conventionally, energy is primarily derived from fossil fuels, which are non-renewable resources. Consequently, many researchers have sought alternative sources of energy. One such innovation is the Dye-Sensitized Solar Cell (DSSC). This study aims to investigate the effect of Antigonon leptopus flower dye as an active material in Dye-Sensitized Solar Cells (DSSC). The absorbance testing was conducted using a UV-Visible Spectrophotometer (1601 PC), while current and voltage (I–V) measurements were carried out using a Keithley instrument. The results showed that the natural dye extracted from the leaves of Antigonon leptopus exhibited an absorbance spectrum in the range of 200–800 nm. These findings suggest that Antigonon leptopus has potential as a natural sensitizer material for application in Dye-Sensitized Solar Cells (DSSC).

Abstract

This study analyzes the seismicity parameters of Lombok Island using ZMAP 7.1 to better understand the region’s earthquake characteristics. The results indicate a high level of seismic activity, with an a-value of 10.257 and an annual a-value of 8.743, corresponding to an average of approximately nine earthquakes per year. The calculated b-value of 1.58 ± 0.07 also reflects high seismicity, suggesting that rocks in the study area have a limited capacity to withstand stress and store energy, thereby favoring the occurrence of low-magnitude events. Conversely, zones with lower b-values are relatively stronger and capable of generating higher-magnitude earthquakes. The predominance of moderate to high b-values across Lombok Island indicates that much of the accumulated energy was released during the 2018 earthquake sequence associated with the Flores back-arc thrust.

Abstract

Misconceptions are incorrect understandings of concepts as recognised by experts. This study aims to analyse junior high school students’ misconceptions on temperature, heat, and expansion using the Three-Tier Test diagnostic tool. The research involved 115 Grade VII and VIII students from public and private junior high schools in Burneh, Bangkalan. A descriptive quantitative approach was applied to classify students into three categories: knowing the concept, misconceptions, and not knowing the concept. The instrument was a three-stage test consisting of 10 multiple-choice questions, reasons, and confidence levels. The findings showed that misconceptions among public junior high school students reached 66.78% (high category), while in private schools the level was 59% (medium category). These differences may stem from several factors, including variations in teaching methods, availability of learning facilities, the effectiveness of instructional media, students’ motivation, and their involvement in the learning process. This study highlights the need for more interactive strategies and effective media that emphasise students’ active role in learning. Addressing misconceptions is essential to improve the quality of science education at the secondary school level.
