Abstract

This study examines the moral crisis occurring within contemporary educational settings, marked by declining honesty, responsibility, and respect among students. The purpose of this research is to analyze the relevance of perennialism as a philosophical foundation for strengthening moral and character education in the modern era. The study employs a library research method by reviewing books, scientific articles, and authoritative documents related to perennialism, morality, and Islamic education. Data were analyzed using content analysis through three stages: data reduction, thematic classification, and conceptual synthesis. The results indicate that perennialism emphasizes universal and timeless values, character formation through intellectual discipline, and the central role of teachers as moral guides. These principles align closely with the aims of Islamic education, which prioritizes the development of noble character. The study concludes that perennialism holds strong relevance in addressing moral degradation among students and recommends its integration into character-based curricula, teacher competence development, and Islamic educational practices. Keywords: perennialism, moral crisis, character education, Islamic education

Abstract

Very High Resolution Satellite Image (VHRSI) data for Indonesian Government license is required by ministries/agencies, TNI, police, and local government to support national programs. But Indonesia did not have a VHRSI data recipient facility to directly acquire this data. In accordance with Law 21/2013 on Space, LAPAN is mandate to provide high resolution satellite data, and based on a roadmap for provision of satellite data in 2017, LAPAN will provide a VHRSI data reception facility through direct receiving system (DRS). This will be more efficient than other methods in providing the data. Priority provision of satellite data is for acquiring Pleiades and TerraSAR-X operating in the frequency range 8 GHz (X-Band). Therefore, to receive both data, it requires antenna subsystem with optimum coverage throughout Indonesia. Parameters to obtain the minimum antenna specifications include Free Space Loss (FSL), Carrier to Noise Ratio (C/No) and Antenna Gain to Noise Temperature (G/T). The calculation of G/T antenna is done for both satellites based on satellite parameters and analysis of antenna product availability in the market. Based on the calculation of satellite parameters shows that the minimum G/T value with the elevation of 5 degrees is 27.71 dB/K for Pleiades data reception and the minimum G/T value of 26.10 dB/K for the TerraSAR-X data reception. In general, the minimum G/T value for receiving the Pleiades and TerraSAR-X data is at 28 dB/K. While based on the calculation of antenna products availability in the market is require G/T value of 33.45 dB /K for the elevation of 5 degrees with a diameter of 7.5 mm antenna. This can be conclude that the antenna products meets the minimum requirements specification and to receive both satellite data. Â However, both calculation for the antenna subsystem still will be evaluated further in order to be directly installed at Parepare Remote Earth Station (SPBJ), South Sulawesi.

Abstract

This study aims to examine the relationship between learning motivation—both intrinsic and extrinsic—and academic achievement among students at SMP Darul Akhlaq, Probolinggo Regency. The research employed a quantitative correlational approach involving 34 students from three grade levels in the 2024/2025 academic year. Data were collected through a Likert-scale questionnaire and academic report documentation, then analyzed using SPSS 24. Validity testing confirmed that all questionnaire items were valid, and the reliability test yielded a Cronbach’s Alpha value of 0.581, indicating acceptable reliability. Simple linear regression analysis showed an R value of 0.717 and R² of 0.514, indicating that learning motivation contributes 51.4% to variations in students’ academic achievement. These findings underscore the significant role of motivation in academic success and highlight the need for school-based interventions to create a supportive learning environment. This study offers contextual contributions by focusing on an Islamic school setting, which remains underexplored in research on this topic.

Abstract

The rapid development of digital technology, particularly Artificial Intelligence (AI), has significantly influenced educational practices, including Islamic Religious Education (PAI). A major issue lies in how AI can be implemented effectively without undermining the spiritual, moral, and character-building values that are central to Islamic education. This study aims to examine the implementation of Artificial Intelligence in Islamic Religious Education learning in the era of school digitalization, focusing on its concepts, forms of application, teachers’ roles, benefits, as well as challenges and ethical considerations. This research employs a qualitative library research method. Data were collected from reputable academic journals, scholarly books, proceedings, and relevant official documents, and analyzed using content analysis techniques through data reduction, data display, and conclusion drawing. The findings indicate that AI has substantial potential to enhance PAI learning through personalized learning systems, adaptive learning media, and data-driven assessments. However, its implementation requires strong teacher supervision, adequate digital literacy, and alignment with Islamic values to prevent the marginalization of teachers’ moral and spiritual roles. In conclusion, Artificial Intelligence serves as a supportive tool in Islamic Religious Education and must be applied wisely, ethically, and in accordance with the fundamental objectives of Islamic education.

Abstract

Red mud, yang merupakan residu utama dari proses Bayer dalam pengolahan bauksit, masih mengandung sejumlah oksida logam berharga seperti Al₂O₃, Fe₂O₃, SiO₂, dan TiO₂. Karakteristik ini menjadikan red mud potensial sebagai sumber sekunder logam, meskipun selama ini lebih banyak diperlakukan sebagai limbah berbahaya. Penelitian ini bertujuan untuk mengevaluasi efektivitas berbagai jenis pelarut asam kuat, yaitu HCl, H₂SO₄, dan HBr, dalam proses leaching konvesional menggunakan labu ukur 2 dengan penutup kondensor spiral magnetik, guna mengetahui kondisi operasi optimum serta kecenderungan selektivitas pelarutan terhadap unsur-unsur utama. Metode yang digunakan adalah leaching dengan konsentrasi asam 0.5 M untuk larutan HCl dan H2SO4 waktu 6 jam dan konsentrasi 4.41 M waktu 4 jam pada larutan HBr kondisi refluks diikuti analisis residu padat menggunakan X-Ray Fluorescence (XRF). Hasil penelitian menunjukkan bahwa jenis pelarut memberikan pengaruh signifikan terhadap komposisi residu red mud. Perlakuan dengan HCl memperkaya kandungan Al₂O₃ dalam residu hingga 59,23%, menunjukkan selektivitas tinggi terhadap pelarutan pengotor. Sebaliknya, H₂SO₄ menurunkan Al₂O₃ menjadi 50,44% disertai peningkatan Fe₂O₃ dan SiO₂, sedangkan HBr menghasilkan penurunan drastis Al₂O₃ hingga 28,53% dengan pengayaan signifikan pada Fe₂O₃ dan SiO₂. Hasil ini menegaskan bahwa pemilihan jenis pelarut menentukan arah pemanfaatan red mud: HCl lebih sesuai untuk memperkaya alumina dalam residu, sementara H₂SO₄ dan HBr lebih potensial untuk menghasilkan residu kaya oksida besi, silika, dan titania. Temuan ini memberikan kontribusi terhadap strategi pemanfaatan red mud sebagai sumber sekunder logam bernilai, sejalan dengan prinsip ekonomi sirkular dan pengelolaan limbah berkelanjutan.

Abstract

This study aims to analyze the effect of Phenomenon-Based Experiential Learning integrated with Formative Assessment on improving students’ scientific literacy in the topic of static fluids. The research employed a quasi-experimental method with a control group Pre-test–Post-test design, involving 71 eleventh-grade students from one of the Islamic Senior High Schools (MAN) in Padangsidimpuan, Indonesia. The experimental class received instruction using the Phenomenon-Based Experiential Learning model accompanied by Formative Assessment, while the control class was taught through conventional learning. Data were collected using eight essay questions covering the topics of hydrostatic pressure, Pascal’s law, and Archimedes’ principle. The findings revealed a significant difference between the two classes, with an N-gain score of 0.66 (medium category) in the experimental class and 0.29 (low category) in the control class. The analysis of each scientific literacy indicator also showed that the Explain Phenomena Scientifically (EPS) and Interpret Data and Evidence Scientifically (IDES) indicators achieved high improvement categories, while the Evaluate and Design Scientific Enquiry (EDSE) indicator increased within the medium category. These results indicate that Phenomenon-Based Experiential Learning integrated with Formative Assessment is effective in enhancing students’ scientific literacy skills.

Abstract

This study aims to examine the effect of capital structure and profitability on firm value in PT United Tractors Tbk for the period 2014–2023. The variables used in this research include capital structure measured by the Debt to Equity Ratio (DER), profitability measured by the Return on Assets (ROA), and firm value measured by the Price to Book Value (PBV). This research employs a quantitative approach with multiple linear regression analysis. The results indicate that partially, capital structure (DER) has no significant effect on firm value, with a significance value of 0.100 > 0.05. Meanwhile, profitability (ROA) has a significant and negative effect on firm value, with a significance value of 0.003 < 0.05 and a regression coefficient of –0,069. Simultaneously, capital structure and profitability significantly influence firm value, as evidenced by the F-statistic of 9.836 greater than the F-table value of 4.74 with a significance level of 0.009 < 0.05. These findings suggest that the combination of financing decisions and profitability performance jointly shapes investor perceptions of firm value, although DER individually does not play a significant role.
