Abstract

In advanced clean energy technologies, rare earth elements (REEs) are an important component. The position of rare earth elements in the future is increasingly strategic so it is necessary to strive to be developed sustainably. At the southern tip of Lampung province, rare earth elements are not yet known. The aims of this study were to analyze the magnetic susceptibility value, composition and percentage of rare earth elements, and the relationship of rare earth elements with magnetic mineral concentrations in pumice at the southern tip of Lampung Province. The method employed is rock magnetic method with Bartington Magnetic Susceptibility Meter Type B and X-Ray Fluorescence. Pumice in the southern region of Lampung Province has diverse magnetic susceptibility values, pumice from Bandar Lampung City has the highest magnetic susceptibility value, while the lowest is in South Lampung Regency. This pumice has antiferromagnetic and ferrimagnetic magnetic properties, and was found to have almost no superparamagnetic grains and also found a mixture of superparamagnetic and coarse grains. The composition of rare earth elements contained in pumice at the southern tip of Lampung Province obtained 3 rare earth elements, samples from Bandar Lampung City contained europium, cerium, and yttrium elements and samples from South Lampung Regency contained europium and yttrium elements. Rare earth elements and magnetic mineral concentration have a relationship, the obtained values decrease with increasing percentage of rare earth elements.

Abstract

Rare earth elements are part of one of the strategic minerals and are included in the "critical minerals". Concentrations of rare earth elements are economically precious deposits that can be used as mining commodities. Pumice is the result of volcanic eruptions and it is one of the minerals containing the rare earth elements, one of which is found in Sigura-Gura, North Sumatra. The research aims to determine the composition of rare earth elements, the relationship between rare earth elements and magnetic mineral concentration, and to determine the concentration of magnetic minerals in pumice in Sigura-gura. The method employed is rock magnetic method with Bartington Magnetic Susceptibility Meter Sensor type B (MS2B), and X-Ray Fluorescence (XRF). Results indicated that Sigura-Gura pumice samples, and Sigura-Gura Waterfall have quite varied magnetic mineral concentrations with a range of values from 111,3 x 10-8m3/kg to 349,9 x 10-8m3/kg, with antiferromagnetic magnetic properties and grain types with almost no SP grains. Samples of Sigura-Gura pumice contain elements of Eu, Ce, and Y, while samples from Sigura-Gura Waterfall contain elements of Eu and Y. There is a correlation between the amount of magnetic minerals and rare elements, and the more elements are present in a sample, the lower the value that is produce, and the greater the percentage of elements obtained, the smaller (%) is obtained.

Abstract

Indonesia is a country prone to earthquake disasters, because Indonesia is located in the collision area between plates, and one of the areas in Indonesia where plate movements often occur is Mentawai. Analysis of waveform data on the 2022 earthquake in the Mentawai region was carried out to determine the type of fault. The data used in this research is local seismic data downloaded from webdc.eu. Seismic data was analyzed using waveform inversion method implemented in ISOLA program. In the ISOLA program, data processing is carried out which includes: inputting 3-component seismic data, earthquake info events, selecting stations, green functions, performing inversion, and displaying results in the form of tensor moment values, strike, dip, and rake values. From the data analysis, the moment tensor value is obtained with the range of each component of M11 is -8.348 to -3.673, M22 is 0.710 to -2.037, M33 is 7.639 to 5.710, M31 is 2.050 to 3.761, M32 is 3.484 to -5.672, M12 is -2.751 to 2.455. Then the inversion results obtained in the form of fault parameters, namely strike, dip, and rake for two nodals that will be analyzed to determine the fault plane. Based on the moment tensor value, it is found that the type of earthquake fault in 2022 in Mentawai region is dominated by reverse fault and oblique fault patterns.

Abstract

Edupark is an educational park concept that combines educational and recreational elements in a contextual and enjoyable learning environment. Meer Von Kandi was selected as the location for developing a physics learning module due to its rich potential for physics concepts, strategic location, and the fact that it has not been previously used as a research object. Attractions at this site such as a water slide, tipping bucket, and a replica of a Dutch windmill contain various physics concepts including work and energy, motion kinematics, force, and rotational dynamics. This study uses the EDUPARK development model, which consists of seven stages, focusing on the first three stages, namely EDU: Edupark Finding, Direct Observation, and Understanding of Teacher, Student, and Curriculum Characteristics. Data were collected through direct observation, teacher interviews, and student questionnaires. The results indicate that most students have a dominant visual learning style, yet their recognition of physics concepts in the tourist site remains low. These findings serve as a fundamental basis for designing a contextual physics learning module based on Problem Based Learning (PBL), which is relevant to the surrounding environment and can enhance students’ interest and understanding in learning physics.

Abstract

City Park Cindua Mato is a green open space located in the center of Batusangkar city and serves as a place for recreation, sports, and social interaction. The existence of facilities such as basketball courts and reflection stone rides make this park an environment rich in phenomena that can be studied scientifically. Despite having the potential of an environment rich in physical phenomena, its utilization in the context of education is still very limited. Problems found based on direct observation show that students often have difficulty in understanding physics concepts because the teaching materials used tend to be theoretical. Observations also show a lack of learner involvement in learning because the media used has not been able to attract their attention, especially those with visual learning styles. In addition, the teacher said that the current teaching materials have not utilized local potential as a source of learning, so students feel that the material presented is less relevant to their daily lives. This research aims to identify the needs of teaching materials that are in accordance with the characteristics of students and the surrounding environment. This research is a preliminary study of the research and development method with the EDUPARK model, which at this stage is focused on the EDU stage. Data were collected through interviews with 3 physics teachers and distributing questionnaires to 31 students of Class XI Phase F Moving Physics 1 SMAN 1 Sungai Tarab. The results of the analysis show that the available teaching materials have not accommodated the local potential and learning styles of students optimally. Therefore, a teaching material is needed in the form of a physics enrichment book integrated with City Park Cindua Mato Batusangkar that is in accordance with the characteristics of students and their learning environment.
