Abstract

This study aims to analyze the effect of temperature, humidity, air speed and sunlight intensity on the electricity generated by solar panels. The research method used is the experimental method, by collecting data directly using two solar panels arranged in series and parallel and carried out in two different places, namely the coastal area and the highlands. The results showed that the temperature, humidity and air velocity with tcount were -0.5765; 0.0063; and 0.5608. The value of tcount is smaller than ttable 2.2281 indicating there is no significant effect between temperature, humidity and air velocity on solar panel electric power. For light intensity, the tcount value is 2.301. The value of tcount is greater than ttable 2.2281, so it can be concluded that there is a significant effect between light intensity and solar panel electric power.

Abstract

Indonesia is on the path of the "Pacific Ring of Fire," so it has a high risk of catastrophic volcanic eruptions. One of the active volcanoes that has the potential to have a big impact is Mount Kaba. To improve students' understanding of disaster mitigation, this study aims to develop and validate a science learning e-module about volcanoes that is integrated with the disaster mitigation of the eruption of Mount Kaba. This study uses a qualitative descriptive method with a 4D model Research and Development (R&D) approach, which consists of the Define, Design, Develop, and Disseminate stages, but only carried out until the development stage, namely validation. Data was collected through observations, questionnaires, and interviews involving teachers and validators from among disaster mitigation and science education experts. The validation results show that the e-module obtained an average score of 92% with the category "Very Feasible" based on the feasibility of content, language, and graphic display. These results indicate that the e-module has great potential as a learning medium for disaster mitigation in schools.

Abstract

The purpose of this study was to determine the NPK value, biomass increase, and pH as the effect of the use of variations in Chinese cabbage and papaya waste feed to reduce environmental pollution and also increase the benefits of organic waste, and organic vegetable and fruit waste has the potential to fertilize the soil. This study was conducted on July 22, 2024 to August 19, 2024 at the Sumber Belajar Ilmu Hayati Ruyani (Bengkulu) and used the RAL (Complete Randomized Design) research method. Data analysis was carried out using an analytical balance, pH paper, and NPK level testing carried out at the Soil Science Laboratory, University of Bengkulu on November 18, 2024 using the methods, namely Nitrogen (Kjeldahl or spectrophotometric method), Phosphorus (Sulfuric acid method followed by spectrophotometric method), Potassium (Extraction method followed by analysis using spectrophotometry). The results of the study showed that the highest NPK levels in sequence were Nitrogen (N) 2.05% in the 100% (Chinese cabbage) feed variation, Phosphorus (P) 0.58% in the 75% (papaya): 25% (Chinese cabbage) feed variation and potassium (K) 0.40% in the 50% (Chinese cabbage): 50% (papaya) feed variation. The highest biomass increase was obtained in the 100% (papaya) feed variation with a weight increase of 27.4g and the highest pH in the 100% (papaya) variation of 6.8 in the normal category. Based on the results of data analysis, it can be concluded that the addition of earthworms Lumbricus rubellus in making vermicompost can degrade Chinese cabbage and papaya waste into usable products, and the use of Chinese cabbage and papaya waste as feed in making vermicompost can increase NPK levels, Biomass and soil pH.

Abstract

This study aims to develop an Augmented Reality (AR)-based physics e-module that integrates landslide disaster mitigation within the topic of work and energy to improve students’ conceptual mastery and disaster preparedness. To support contextual learning, the study also identifies the predominant frequency (f₀), amplification factor (A0), and seismic vulnerability index (Kg) at MAN Insan Cendekia Bengkulu Tengah using the microtremor method. The development followed the 4D model Define, Design, Develop, and Disseminate including needs analysis, product design, expert validation, and both limited and large-scale trials. Expert validation showed the module was highly feasible, with scores of 99% for content and 97% for media. The large-scale trial involved 45 students, namely 30 in the experimental group using the AR-based e-module and 15 in the control group using printed textbooks. Results indicated that the experimental group achieved an average N-Gain of 0.470 (moderate), with 70% of students in the moderate to high category. In contrast, the control group obtained an N-Gain of only 0.180 (low). An independent t-test showed a statistically significant improvement within the experimental group (p = 0.001) and a significant difference between groups (p = 0.000). The Chi-Square test revealed significant differences in cognitive (p = 0.000) and conative (p = 0.003) aspects, while the affective aspect remained statistically insignificant. Overall, the AR-based e-module proves to be a relevant and effective tool to strengthen students’ conceptual understanding and readiness in responding to disaster risks through contextual physics education

Abstract

This research aims to evaluate the potential of yellow pumpkin peel (Cucurbita moschata) and king banana peel (Musa paradisiaca) as raw materials for bioethanol production, based on the alcohol content produced. The bioethanol production process includes hydrolysis using 5% HCl, fermentation for 7 days with adding nutrients (NPK and urea), and purification through distillation. The research results show that the combination of yellow pumpkin peel and king banana peel, adding NPK, produces the highest ethanol content of 13%. Meanwhile, the lowest content of 4% was obtained from the fermentation of the king banana peel without additional nutrients. The addition of nutrients, particularly NPK, has been proven to enhance the activity of microorganisms in natural fermentation, thereby accelerating the conversion of carbohydrates into ethanol. With the ethanol content produced, the bioethanol from this organic waste can be used practically as E5-type blended fuel without requiring any modifications to vehicle engines. This result shows that fruit peel waste can be an environmentally friendly and economical alternative for renewable energy.

Abstract

Environmental Physics concepts are very likely to be explored to facilitate the cultivation of spiritual attitudes because they are closely related to phenomena in everyday life. Visual media can help visualize environmental phenomena so that they are easier to understand. This study aims to instill spiritual values through the concept of Environmental Physics as an alternative learning that focuses on the affective domain with the help of visual media. This study involved 15 science education postgraduate students. This research used a Pre-experimental design with a Shoot Case Study. The research design includes pre-experiment, experiment, and analysis of experimental data results. In the pre-experiment stage, the concept of environmental physics and spiritual attitudes were analyzed, learning tools were prepared, and questionnaire instruments for student perceptions related to the cultivation of spiritual values were prepared. At the experimental stage, the implementation of Environmental Physics learning integrated with spiritual values was carried out. In the post-experiment stage, data analysis and interpretation were carried out to answer research problems. Based on the results of data analysis, it is known that 92.15% of respondents strongly agree that learning environmental physics can instill awareness of the nature of God. Based on the results of the open-ended questionnaire, it is known that students can explain the content of spiritual values in various phenomena in the environment. In addition, students stated that visual media can facilitate the activity of instilling awareness that God is omnipotent over all the universe. Thus it can be concluded that environmental physics learning activities can instil spiritual attitudes through environmental physics content assisted by visual media. Science content, especially environmental physics, is very relevant in instilling spiritual values
