The use of CFC refrigerants (Chloro Fluoro Carbon) leads to destruction of ozone layer and global warming. An alternative refrigerant is hydrocarbon refrigerant, but it has the disadvantage of easily exploded. This experimental study has been conducted to study the effect of addition of TiO2, which are flame retardant, on the performance of hydrocarbon refrigerant R600a (nanorefrigeran TiO2-R600a). Test of Performance conducted according to refrigerants national standards IEC 60335-2-24-2010. The result is R600a-TiO2 is safe and efficient to be used as a refrigerant without any modification on refrigerator. TiO2 increases the thermal conductivity and heat transfer of refrigerant. The best performance is obtained at TiO2 concentration of 1 g / L (COP = 4,821). It is expected that the nanorefrigeran TiO2-R600a can be used as the primary refrigerant in the future that are environmentally friendly and efficient.Â Keywords: Â Nano-Refrigerant, R600A, TiO2, COP

MTs AL Munawarah is one of the madrasas under the auspices of the Al Munawarah Islamic Boarding School in Jombang Regency. The curriculum used in the teaching and learning process at this madrasa is the K13 curriculum. This curriculum is very helpful for teachers in developing learning materials in terms of material exploration to how to present the exercises used. The researchers here want to help develop the teaching materials used in accordance with the characteristics of the k13 curriculum. From this development, new K13-based teaching materials emerged that could be used by teachers, especially Arabic teachers. This research approach using developmental (R & D) for Borg and Gall theory consists of: (1) preliminary study, (2) planning, (3) hypothetical model development, (4) hypothetical model review, (5) revision, (6 ) limited trial, (7) revision of test results. From the previous statement, the researchers determined the formulation of the problem: (1) How to prepare reading learning teaching materials using a scientific approach at MTS Al Munawarah Diwek - Jombang. and (2) the characteristics of the preparation of teaching materials for learning to read using a scientific approach at MTS Al Munawarah Diwek - Jombang. Based on the assessment of design experts obtained 88.3% very good standard. The expert's assessment of the content of the book obtained a very good standard of 81.53%. The assessment of the student and teacher questionnaires came in at 90%, which is at the level of "very good." This case shows that this book is very good to use in teaching Arabic from the results of assessments and suggestions from experts and also from the responses of teachers and students.

This paper applies Nasr Hamid Abu Zayd’s contextual hermeneutics to four Qur’anic verses often invoked in Islamic political discourse: QS. al-Nisā’ [4]:59, QS. al-Baqarah [2]:30, QS. al-Shūrā [42]:38, and QS. al-Mā’idah [5]:44. Traditional interpretations have frequently endorsed literal and authoritarian readings, framing obedience, governance, and divine law as rigid imperatives. By engaging Abu Zayd’s concept of tārīkhiyyat al-dalālah (the historicity of meaning), this study reinterprets these verses through their socio-historical contexts and ethical substance. The analysis finds that each verse contains dynamic ethical imperatives: conditional obedience, ecological stewardship, participatory governance, and values-based jurisprudence. Abu Zayd’s methodology reframes Islamic political thought as a field grounded not in legal absolutism, but in moral dialogue. This approach supports a pluralistic, just, and context-sensitive reading of the Qur’an, offering new possibilities for integrating Islamic teachings with contemporary values of justice, human rights, and ethical leadership

This article critically evaluates contemporary Islamic ecological piety and secular ecological ideologies to propose a spiritually enriched framework for meaningful environmental engagement. Employing a qualitative, philosophical-reflective methodology, it integrates conceptual analysis with comparative philosophical discussions between anthropocentric, ecocentric, and theocentric paradigms. The findings reveal significant shortcomings in current ecological practices, including superficiality within Islamic contexts and ideological limitations in secular ecologism. Although deep ecology offers insightful critiques against anthropocentric perspectives, its secular foundation limits practical implementation among religiously-oriented communities. Reflective insights from Islamic spirituality, notably the principles of tawhid and khalifah, are presented as practical ethical foundations for transformative ecological engagement. These concepts foster deep ecological consciousness and communal responsibility, enabling substantive rather than symbolic environmental actions. The study advocates integrating spiritual ethics within educational and religious institutions, exemplified by successful eco-pesantren models. This research contributes significantly by bridging spiritual and ecological ethics, suggesting practical approaches to ecological sustainability informed by Islamic spirituality, and encourages further empirical exploration into spiritually-based ecological frameworks.

Penelitian ini bertujuan untuk mengkaji secara mendalam pengaruh judi online terhadap siswa Sekolah Menengah Atas (SMA). Judi online merupakan fenomena yang berkembang pesat seiring kemajuan teknologi digital dan internet, yang memungkinkan akses mudah bagi remaja, termasuk siswa SMA. Penelitian ini menggunakan metode kualitatif dengan pendekatan studi literatur dan wawancara mendalam terhadap siswa yang terlibat dalam aktivitas judi online. Hasil penelitian menunjukkan bahwa judi online berdampak negatif secara signifikan terhadap aspek akademik, sosial, psikologis, dan ekonomi siswa. Dampak tersebut meliputi penurunan prestasi belajar, gangguan hubungan sosial, kecanduan yang memicu stres dan gangguan mental, serta kerugian finansial yang dapat memicu perilaku kriminal. Oleh karena itu, diperlukan upaya pencegahan dan penanganan terpadu dari pihak sekolah, keluarga, dan pemerintah untuk meminimalisasi dampak buruk judi online bagi siswa SMA.

In general, sorting waste is still done manually by human hands. For example, it is still done manually by human hands to sort metal and non-metal waste from a pile of garbage. This results in less efficiency in terms of time and energy and also greatly impacts the health of oneself and others. With these conditions, one solution is to build a metal and non-metallic waste sorting system in the trash. The metal and non-metal waste sorting system that is made can sort metal and non-metal waste automatically because it is equipped with an inductive proximity sensor system which functions to detect metal waste plus a NodeMCU module which functions as a data sender of information on the weight capacity of the waste. With this automatic waste sorting system, waste can be sorted according to predetermined types of waste such as metal waste and non-metal waste.
