Abstract

This article aims to find out the form of connection that occurred between the Prophet Muhammad and the Jews in Madina. The population of Madina consists of a wide variety of tribes, religions, and social and economic levels. In this situation, it is perilous for conflict to occur. It is known that there were three popular Jewish groups in Madina, namely the Banu Qainuqā, the Banu Naḍīr, and the Banu Qurayẓah. In addition, the author wants to explore the factors that influence the dynamics of the connection between the Prophet Muhammad SAW and the Jews. In order to find out the answer to the question, this research was conducted using qualitative methods from the perspective of Ralf Dahrendorf's conflict theory. The results of this study were: First, the relations started when the Prophet Muhammad SAW moved to Madina and the involvement of the Jews in a mutual agreement. Furthermore, the axis of the conflict began to appear when there was a debate on the issue of faith and worship. Second, the factors that influenced the relations of the Prophet Muhammad SAW in the perspective of conflict theory were three factor; the factor of the seizure of authority, the ethnocentrism factor and transferred culture factor.

Abstract

Pemanfaatan ampas kopi sebagai material pendukung katalis TiO2 tidak hanya berpotensi untuk mengurangi limbah kopi yang belum dimanfaatkan dengan baik, tetapi juga dapat berperan dalam upaya pengolahan limbah logam berat Cr(VI) yang berbahaya. Salah satu cara pengolahan limbah logam berat Cr(VI) adalah dengan mereduksinya menjadi Cr(III) yang relatif lebih aman dan tidak toksik. Penelitian ini bertujuan untuk mengetahui karakteristik morfologi, komposisi unsur, luas permukaan spesifik, dan porositas dari material komposit TiO2-Ampas Kopi (TiO2-AK). Material TiO2-AK disintesis menggunakan metode hidrotermal dengan memvariasikan komposisi massa antara TiO2 dengan AK (1:9, 2:8, 3:7, dan 4:6). Material hasil sintesis dikarakterisasi menggunakan SEM-EDS dan adsorpsi-desorpsi nitrogen. Selain itu, dikaji juga aktivitas fotokatalitik material hasil sintesis dalam mereduksi Cr(VI). Hasil penelitian menunjukkan bahwa TiO2 berhasil menempel pada permukaan ampas kopi. Material komposit TiO2-AK yang disintesis memiliki struktur mesoporous dengan luas permukaan spesifik berkisar antara 23,354 m2/g hingga 30,281 m2/g. Penggunaan adsorben ampas kopi sebagai material pendukung TiO2 membentuk sinergi yang baik antara mekanisme adsorpsi dan fotokatalitik sehingga dapat mereduksi Cr(VI) dengan lebih cepat. Aktivitas fotokatalitik paling tinggi ditunjukkan oleh material TiO2-AK dengan variasi massa 2:8 yang mampu mereduksi Cr(VI) hingga 61,8% dalam waktu 6 jam iradiasi sinar UV.

Abstract

Every learning activity must involve students so that they can experience what they are learning. In order to achieve the best learning results, students must be actively involved in learning activities. Reciprocal learning is an independent learning activity in learning subject matter as well as an active and creative role as an educator in conveying all information to his friends. The existence of student confidence in active and independent learning will have a positive effect on student learning outcomes. Instruments used in the form of questionnaires and tests. The questionnaire is in the form of a number of written questions used to obtain information from the respondent, while the test is in the form of a list of questions or items. The analysis in this study uses multiple linear regression tests.

Abstract

This comprehensive research has explored the potential of enhancing dye-sensitized solar cells (DSSC) by harnessing environmentally friendly natural dyes, such as chlorophyll pigments from pandanus (664.1 nm) and papaya leaves (664.0 nm), as well as betacyanin pigments from sappan-mangosteen (536.2 nm). Electrochemical analyses elucidated the energy band gaps, revealing a hierarchy with the smallest band gap observed for papaya leaves (1.387 eV), followed closely by sappan-mangosteen (1.389 eV) and pandan leaves (1.396 eV). This research effectively addressed the persistent issue of electrolyte leakage in DSSC development by introducing a polymer electrolyte derived from polyvinylidene fluoride (PVDF) through electrospinning and phase inversion techniques. SEM characterization results and thermogravimetric analysis underscored the superior characteristics and high thermal stability of the PVDF nanofiber polymer for DSSC applications. The study's pivotal findings underscore the remarkable DSSC performance achieved with chlorophyll pigment from papaya leaves, reaching 1.31% efficiency without a polymer electrolyte. Moreover, the sappan-mangosteen dye emerged as a promising contender with the highest efficiency values when applied with polymer electrolyte, recording rates of 1.17% for PVDF NF and 0.95% for PVDF, which are notably comparable to the efficiency of liquid electrolyte at 1.26%.
