Abstract

The implementation of digital technology has had a significant positive impact on education by expanding access to learning, allowing students to learn anytime and anywhere digitally. This study aims to observe and analyze the edupark at the Bukit Langkisau tourist attraction and the relationship between physics materials and the tourist attraction. After the analysis, this Edupark e-book can be developed. The results of this study indicate that printed books are still predominantly used in schools, and the use of non-printed books is still lacking; the average results of student knowledge and skills are still low; learning materials integrated with Edupark at tourist attractions are still rarely used; and have not been able to improve students' digital literacy. The conclusion of this study is the need to develop an integrated physics education e-book at tourist destinations. The Bukik Langkisau tourist attraction has the potential to be used as an educational park for learning, but has not been optimally implemented due to difficult access to the tourist location. Therefore, the purpose of this study is to develop an integrated physics education park e-book at the Bukit Langkisau tourist attraction.

Abstract

Through the use of online graphic design platform CANVA and waste management programs, this study seeks to create electronic student worksheets to enhance students environmental awareness using Model Problem Based Learning on alternative energy. The ASSURE model, which includes the development stage, is applied uses the Research and Development methodology. At SMA Negeri 8 Padang, observations the school environment and needs analysis involving 1 physics teacher and 28 students were conducted as part of the analysis stage. Based on these initial observations, it was found that students' environmental awareness was still low. In addition, students understanding of alternative energy was quite limited because digital teaching materials had not been fully utilized. Based on these identified problems, digital student worksheets on waste management programs were created to boost environmental awareness using the Model PBL. By using the Kappa Moment, the product feasibility validity test test conducted by three physics lecturers confirmed the content, language, presentation, and graphics were valid. Revisions were made based on their feedback. Based on results, it was shown the electronic student worksheet on alternative energy based on the waste management program "Nabuang Sarok" is appropriate to use, especially in the independent curriculum, to improve students' environmental awareness.

Abstract

Electrical energy has become a human need along with economic improvements and technological advances that require an unlimited supply of energy. Its nature is limited to fossil energy sources and also causes environmental pollution, so it is necessary to use renewable energy as another energy source to overcome this problem. Solar energy is freely available, is an environmentally friendly energy source whose application results have been proven and have promising prospects for the future. This paper presents the results of a research review on the use of solar energy as an alternative source of renewable energy, the basic concept of obtaining it and some results of using this energy. Next, we will briefly review the potential and use of solar energy sources in Indonesia. The high potential of solar energy in Indonesia needs to be processed and regulations that support the development of solar energy power plants as an alternative energy. Technically, solar photovoltaic energy has the potential to become an alternative energy source for the masses in the future as a substitute for fossil energy and to meet the electrical energy needs of remote areas.

Abstract

This study investigates the relationship between SiO₂ composition and magnetic properties of Lampung Tuff from Hatta Bekauheni using an integrated approach combining rock magnetism and portable geochemical analysis. Magnetic susceptibility measurements were conducted using a Bartington MS2B sensor at low and high frequencies to determine χlf and χfd (%), while elemental composition was analyzed using Portable X-Ray Fluorescence (Portable XRF). The results indicate that all samples exhibit ferrimagnetic behavior, reflecting the presence of magnetic minerals such as magnetite or titanomagnetite with varying concentrations and grain sizes. The χfd (%) values suggest a mixture of superparamagnetic and coarser grains, indicating heterogeneous depositional and post-depositional processes. SiO₂ content varies among samples, representing local geochemical differentiation of volcanic material. However, regression analysis shows a very weak correlation between SiO₂ and magnetic parameters, as indicated by low coefficients of determination. These findings demonstrate that magnetic properties are primarily controlled by mineralogical factors rather than silica composition. The integration of magnetic susceptibility and Portable XRF provides an efficient, non-destructive framework for comprehensive volcanic material characterization.

Abstract

Mount Singgalang is a volcano that has erupted after 1600. Several types of volcanic rocks found around the Mount Singgalang area are Basalt, Andesite, Tuff Breccia, Lava Breccia, and Pumice tuff. Where, andesite and tuff pumice Mount Singgalang originated from the maninjau eruption. Pumice has several minerals, namely cristobalite, feldspar, quartz, obsidian, cristobalite, and tridymite. Pumice has one of the magnetic minerals, namely hematite (Fe2O3), but it is not known how much magnetic mineral content in it. This study aims to determine the abundance of magnetic minerals (magnetic susceptibility) in pumice around Mount Singgalang, West Sumatra. The method used is the rock magnetism method, where this method can investigate the magnetic properties of a material. The instrument used is the Bartington Magnetic Susceptibility Meter. The magnetic susceptibility value of Pumice (Pumice) in the area around Mount Singgalang, West Sumatra, where is the abundance of magnetic minerals in Pumice Rock TDK 20-02 > TDK 20-03 > TDK 20-10. The TDK 20-02 sample has a lot of superparamagnetic grains due to its low susceptibility value and high-Frequency Dependent Susceptibility, while the TDK 20-10 sample has little or almost no superparamagnetic grains due to the high susceptibility value and low-Frequency Dependent Susceptibility.

Abstract

Pumice is a silica-rich volcanic product that provides important information on magma characteristics and petrogenetic processes. This study aims to characterize the major and trace element geochemistry of Pumice from the Maninjau Caldera, West Sumatra. Pumice samples were analyzed to determine their major and trace element compositions and interpreted based on magma geochemistry. The results show that the Pumice is dominated by SiO₂ (75.33%) and Al₂O₃ (17.46%), whereas K₂O, Fe₂O₃, CaO, and TiO₂ occur in lower concentrations. Trace elements are dominated by Th, Rb, and Sr, while Zr, Y, and Nb occur in relatively low amounts. These geochemical characteristics indicate that the Pumice originated from felsic magma with rhyolitic to dacitic composition that experienced advanced magmatic differentiation through crystal fractionation, particularly of plagioclase. This study demonstrates that pXRF is an effective, rapid, efficient, and non-destructive method for preliminary geochemical characterization of volcanic rocks.
