Abstract

Solar energy is energy in the form of rays and heat from the sun. This energy can be harnessed using various technologies, such as solar panels. Solar panels consist of solar cells that convert light into electrical energy. The topic of this research is the use of solar panels for battery charging on electric tricycles. The process of developing an electric tricycle with solar power consists of several stages, from the preparation of the tricycle, the development design, and the manufacture of the solar panel frame and holder to the assembly and testing process. The result of this research is an electric tricycle uses a 48 Volt with two units solar panel 100 Wp, 7.2 Ah battery with a charging time of 1 hour 22 minutes, using a 350 Watt Brushless DC motor. The maximum speed of an electric tricycle with solar panels is as expected: a distance range of 45 km and a load of 120 kg (per person).

Abstract

This research stems from using learning materials that still consist mainly of textbooks and occasionally printed modules, resulting in low levels of students' critical thinking skills. This study aims to investigate the influence of an e-module based on the guided inquiry learning model on students' critical thinking skills on the topic of work and energy. The research method is a quasi-experimental design with a pretest-posttest control group design. The population in this study comprises all tenth-grade science students at SMA Negeri 3 Kota Tasikmalaya, and the sample was selected using cluster random sampling technique, with Class X MIPA 7 as the experimental group and Class X MIPA 8 as the control group. The data analysis technique includes prerequisite testing, hypothesis testing, and N-Gain analysis. Based on the hypothesis test results using the t-test, it was found that , specifically, 3.75 > 1.67, leading to the rejection of . Therefore, it can be concluded that using an e-module based on the guided inquiry learning model influences students' critical thinking skills on work and energy. The improvement in students' critical thinking skills was assessed using the N-Gain test, which yielded an average N-Gain score of 0.41, indicating moderate improvement.

Abstract

This research regarding applying science-worked examples in the context of local wisdom to improve students' problem-solving abilities is motivated by students' low problem-solving abilities, especially in science-physics learning. Students' standard problem-solving abilities are due to the lack of practice in the learning process. Through the application of Science Worked Examples, it is hoped that it will be able to help students in the learning process so that they can grow students' problem-solving abilities. The type of research used in this research is a quantitative method with an experimental approach. The subjects used in this research were class VIII A as a control sample and class VIII B as a testing sample at SMP N 2 Garung. The research results showed an increase of 31.9% in the control sample using conventional teaching materials and a rise of 44.1% in the experimental sample using Science Worked Examples. The effectiveness obtained using the N-Gain test was 1.38, so it was concluded that there was a difference in effective improvement where learning with worked example science teaching materials was stated to be more effective.

Abstract

This research aims to analyze the characteristics of superposition waves in the musical instrument known as "saron" in the gamelan ensemble. In this study, three types of gamelan sarons were used as research instruments: "saron demung," "saron barung," and "saron panerus" or "peking." The sounds produced by these musical instruments were recorded, mixed, and analyzed using Audacity software and Spectra Plus Sound Card Edition. The analysis results conducted with Audacity and Spectra Plus Sound Card Edition revealed the presence of superposition waves that either reinforced each other when they had the same phase and frequency or weakened each other when they had different phases and frequencies. Therefore, this study concludes that audio mixing that falls under constructive or reinforcing superposition of waves is the combination of "saron demung" with "saron demung." On the other hand, audio mixing that falls under the destructive superposition of waves includes the varieties of "saron barung" with "peking," "saron barung 1" with "demung," "saron barung 2" with "peking," and "saron barung 2" with "demung."

Abstract

Seismic stratigraphy is one of the efforts in interpreting stratigraphy from seismic data. In seismic data, things that can be construed include faults, facies, depositional environments, sequence boundaries, petroleum systems, etc. Studies related to seismic stratigraphy are an essential part of oil and gas exploration activities. These studies can support the analysis of results in early fields with minimal data or fields without good data. The results of stratigraphic analyses on subsequent seismic data are useful as a basis for further exploration activities. A simple method that can be used to interpret seismic data is by using a wheeler diagram. The interpretation results obtained from stratigraphic analysis on seismic data with a width of 5 Km and a depth of 50 ms are ten faults with a descending pattern, and there are five sequence boundaries based on the continuity pattern of seismic data. Based on the results of stratigraphic interpretation on seismic data, the reservoir deposition environment is in the transition area. The petroleum system that can be indicated from the seismic data is that the reservoir is in the off-lap section and also in the basin floor fan, the source rock is below the reservoir zone, the reservoir migration pattern passes through the fault, and the shale at the top of the reservoir layer can be a seal rock and the trapping pattern in the seismic data is generally a stratigraphy trap

Abstract

Ondel-ondel is one of the well-known local cultures from Jakarta. However, the role of ondel-ondel is not only in switching ceremonies and rituals but can be used as learning media. In addition to local cultural problems that are still not optimal in learning, the learning process must be carried out meaningfully. So, this study aims to analyze ondel-ondel culture from the point of view of Physics (especially on rigid body equilibrium material) and to implement it as learning media in Physics learning to achieve meaningful learning. This research is a mixed method research. Based on the results and discussion obtained, ondel-ondel has many physics concepts. In ondel-ondel, rigid body equilibrium is of special concern because equilibrium is the main focus so that the ondel-ondel remains stable when played without falling. In ondel-ondel culture, the concept of circular motion and heat also applies. The second conclusion obtained from this study is that the implementation of ondel-ondel as a learning medium is proven to realize meaningful learning for students. Achieving meaningful learning through implementing an ondel-ondel as learning media has very good criteria.

Abstract

Geothermal is a renewable energy strategically developed in Indonesia, but its utilization has not been maximized. Geothermal exploration requires high costs, so estimating energy reserves in potential areas is essential. This study was conducted to determine the electrical energy potential of geothermal area "Z" by volumetric method and determine the influence of saturation, porosity, and length of generation time on the potential of geothermal electrical energy. The volumetric method used is the lumped parameter model. The calculation was carried out with variations in water saturation 0% - 80%, rock porosity 10% - 40%, and the length of generation time 25 - 40 years. The highest estimated electrical energy of geothermal area "Z" is 188 MWe obtained at 80% water saturation, 10% porosity, and 25 years generation duration, while the lowest is 80 MWe obtained with 0% water saturation, 40% porosity, and 40 years of generation duration. At the same porosity, the greater the water saturation, the greater the value of geothermal electricity reserves of the area "Z." The greater the porosity, the greater the effect of increasing water saturation on increasing electrical energy reserves. The large porosity of rocks causes their energy to be smaller since the heat dominance of geothermal regions "Z" is given by the heat of rocks. The length of generation time affects the amount of geothermal electrical energy, that is, the longer the production time, the smaller the reserve.

Abstract

One of the biopesticides is derived from The Neem Tree (Azadirachta indica), which has been widely used in India for centuries. The purposes of this study are to examine the historical use of neem trees as biopesticides in ancient India, the adoption and integration of neem tree-based biopesticides in Indonesian agriculture, the cultural and historical context of neem tree use, and the impact of neem tree-based biopesticides on sustainable agriculture. The research design for this study is an ethnographic approach, which involves the systematic observation, documentation, and analysis of the cultural practices and beliefs related to using neem trees as biopesticides. The findings of this study demonstrate that the Neem tree has been widely described as a biopesticide used to control pests in agriculture in ancient Indian literature, such as the Rigveda and Atharvaveda. The neem tree held cultural and spiritual significance in ancient Indian society, associated with deities and religious beliefs. Historical connections between India and Indonesia facilitated the spread of neem tree-based biopesticides to Indonesia, where they were adopted and integrated into traditional agricultural practices. Indonesian farmers embraced neem tree-based biopesticides and recognized their efficacy in pest control, contributing to sustainable agricultural practices.

Abstract

Students poorly understand the magnetic field material concept due to difficulties visualizing it. So, it takes a skill that can support the ability to visualize magnetic field material to practice these skills requires the right strategy and learning media. Therefore, this study aims to develop and determine the feasibility and response of students to the acceptance of Visual Thinking Strategy in Augmented Reality (ViTSAR)  learning media technology to facilitate visual literacy skills on magnetic field material. The research method used is Research and Development  (R&  D) with a  4-D development model (Define, Design, Develop, and Disseminate). Through due diligence conducted by material experts, the average value of all aspects was 6.7 with feasible criteria, and media experts obtained an average value of 6.81 with feasible criteria. In contrast, the trial was limited to 15 3rd-semester students of  Physics Education at Sultan Ageng Tirtayasa University, who responded well to technology acceptance with an overall average assessment result of 6.36. These results show that ViTSAR learning media on magnetic field material can be used as a learning supplement in introductory Physics II lectures on magnetic field material.
