Abstract

This article discusses the influence of patriarchal culture on Tafsir Firdaus Al-Na'im by Thaifur Ali Wafa, who specifically analyzes the interpretation of gender verses. This research shows that the interpretation of Thaifur Ali Wafa still maintains the patriarchal element which states that a man is the leader of the family with greater responsibilities and rights than a woman. The background concludes that Tafsir Firdaus Al-Na'im still contains strong patriarchal elements because it is influenced by socio-cultural norms of Patriarchy using Classical Tafsir reference sources as well as traditional views on gender relations in Islam accompanied by an emphasis on ethics and responsibility. This research aims at how Tafsir Firdaus Al-Na'im answers contemporary issues occurring in the surrounding community. The research method used is a qualitative method or literature with a descriptive approach by collecting data from two types, namely primary data and secondary data.

Abstract

Gastropoda termasuk salah satu kelompok hewan yang memiliki jumlah terbesar dalam dunia hewan dengan jenis yang umum dikenal adalah siput, kerang, dan cumi-cumi. Limbah cangkang merupakan masalah yang harus segera diatasi karena memiliki dampak yang buruk pada makhluk hidup, seperti terjadinya pencemaran tanah dan air. Limbah organik dari cangkang juga dapat mempengaruhi kualitas udara jika terjadi pembusukan dan dapat menimbulkan penyakit ISPA (Infeksi Saluran Pernafasan Atas). Kreca (Bellamya javanica) merupakan salah satu hewan Mollusca yang hidup bebas di daerah persawahan dan dapat dikonsumsi masyarakat. Cangkang kreca mengandung kitin, mineral, kalsium dan protein, sehingga limbah cangkangnya memiliki potensi untuk diolah dan dikembangkan menjadi suatu produk bernilai ekonomi tinggi salah satunya sebagai sumber kitin- kitosan. Kitosan merupakan salah satu turunan dari senyawa kitin diperoleh melalui proses demineralisasi, deproteinasi dan deasetilasi. Penelitian ini bertujuan untuk mengetahui pengaruh perbedaan penggunaan refluksdan magnetic stirrer pada proses isolasi kitosan tahap deasetilasi terhadap persentase rendemen dan derajat deasetilasi kitosan yang dihasilkan. Pada penggunaan refluks didapatkan nilai rendemen yang lebih besar yaitu 10,819% daripada magnetic stirrer. Hasil analisis FTIR dari kitosan yang dihasilkan dari penggunaan refluks dan magnetic stirrer didapatkan beberapa gugus fungsi yaitu gugus OH, CH, CO Amida, CH2 dan COC, dengan nilai derajat deasetilasi pada penggunaan refluks sebesar 38,6% dan 47,8% pada penggunaan magnetic stirrer, sehingga disimpulkan penggunaan magnetic stirrer lebih baik daripada refluks dilihat dari nilai derajat deasetilasinya. Gastropods are among the largest groups of animals in the animal kingdom, with commonly known types being snails, clams, and squid. Shell waste is a problem that needs to be addressed immediately because it has a detrimental impact on living beings, such as causing soil and water pollution. Organic waste from shells can also affect air quality if it decomposes and can cause respiratory infections. Kreca (Bellamya javanica) is one type of mollusk that lives freely in paddy fields and can be consumed by the community. Kreca shells contain chitin, minerals, calcium, and protein, so the shell waste has the potential to be processed and developed into a high-economic-value product, one of which is as a source of chitin-chitosan. Chitosan is a derivative of the chitin compound obtained through the processes of demineralization, deproteinization, and deacetylation. This study aims to determine the effect of using reflux and a magnetic stirrer in the chitosan isolation process at the deacetylation stage on the percentage yield and the degree of deacetylation of the resulting chitosan. Using reflux resulted in a higher yield value of 10.819% compared to the magnetic stirrer. The FTIR analysis results of the chitosan obtained from using reflux and magnetic stirrer showed several functional groups: OH, CH, CO Amide, CH2, and COC, with the degree of deacetylation using reflux being 38.6% and 47.8% using the magnetic stirrer. Therefore, it is concluded that using a magnetic stirrer is better than reflux in terms of the degree of deacetylation.

Abstract

This study examines the classroom as a social system and the factors that influence social interaction in schools, especially in the classroom environment. From the perspective of the sociology of education, schools are understood as complex social systems with teachers, students, curriculum, and rules that interact with each other for educational purposes. The classroom not only functions as a place to learn, but also becomes a vital arena for social interaction between students and between students and teachers. Complex classroom dynamics are formed from the diversity of backgrounds, experiences, interests, personalities, and individual abilities of students. Positive interactions in the classroom are essential to creating a conducive and enjoyable learning environment, while less harmonious interactions can be an obstacle to the learning process. Through interviews with homeroom teachers, it was found that student heterogeneity (economic background, family, and learning readiness) is the main challenge that teachers must address wisely. The dynamics of communication between students vary, from those who are sociable to those who are selective in finding friends, requiring special guidance, especially in group work. The dynamics of communication between teachers and students are generally good, although there are differences in teaching styles among many subject teachers that require students to adapt. Individual differences in interests, personality, and abilities (IQ) also greatly affect social dynamics. Students with low abilities require more attention and motivation, while early interest direction is important to help students focus on the appropriate educational path. Understanding the class as a social system and the interactions within it is very relevant to creating a humanistic and meaningful learning environment. Keywords: Class as a Social System; Social Interaction; Class Dynamics; Sociology of Education; Learning Environment.   Abstrak Penelitian ini mengkaji tentang ruang kelas sebagai suatu sistem sosial dan faktor-faktor yang memengaruhi interaksi sosial di sekolah, khususnya di lingkungan kelas. Dari sudut pandang sosiologi pendidikan, sekolah dipahami sebagai suatu sistem sosial yang kompleks yang terdiri dari guru, siswa, kurikulum, dan aturan yang saling berinteraksi untuk tujuan pendidikan. Ruang kelas tidak hanya berfungsi sebagai tempat belajar, tetapi juga menjadi arena vital terjadinya interaksi sosial antar siswa dan antara siswa dengan guru. Dinamika ruang kelas yang kompleks terbentuk dari keberagaman latar belakang, pengalaman, minat, kepribadian, dan kemampuan individu siswa. Interaksi yang positif di dalam kelas sangat penting untuk menciptakan lingkungan belajar yang kondusif dan menyenangkan, sedangkan interaksi yang kurang harmonis dapat menjadi kendala dalam proses pembelajaran. Melalui wawancara dengan wali kelas, ditemukan bahwa heterogenitas siswa (latar belakang ekonomi, keluarga, dan kesiapan belajar) merupakan tantangan utama yang harus dihadapi oleh guru secara bijaksana. Dinamika komunikasi antar siswa bervariasi, ada yang mudah bergaul, ada yang selektif dalam mencari teman, sehingga memerlukan bimbingan khusus, terutama dalam kerja kelompok. Dinamika komunikasi antara guru dan siswa pada umumnya baik, meskipun terdapat perbedaan gaya mengajar di antara banyak guru mata pelajaran yang mengharuskan siswa untuk beradaptasi. Perbedaan individu dalam hal minat, kepribadian, dan kemampuan (IQ) juga sangat memengaruhi dinamika sosial. Siswa dengan kemampuan rendah memerlukan lebih banyak perhatian dan motivasi, sedangkan arahan minat sejak dini penting untuk membantu siswa fokus pada jalur pendidikan yang tepat. Memahami kelas sebagai sistem sosial dan interaksi di dalamnya sangat relevan untuk menciptakan lingkungan belajar yang humanis dan bermakna. Kata Kunci: Kelas sebagai Sistem Sosial; Interaksi Sosial; Dinamika Kelas; Sosiologi Pendidikan; Lingkungan Belajar.

Abstract

Penelitian ini mengkaji konsep nusyuz melalui pendekatan hermeneutika Amina Wadud dan Khaled Abou El Fadl. Dengan menyoroti penafsiran nusyuz dalam Al-Qur’an khsusunya dalam Q.S An-Nisa’ :34 dan 128, penelitian ini menegaskan perlunya pembacaan ulang terhadap tafsir patriarkal yang telah lama mendominasi tradisi. Amina Wadud melalui hermeneutikanya feminis yang memusatkan pengalaman perempuan dan mendorong pemahaman nusyuz yang kontekstual dan berkeadilan, yang menekankan relasi timbal balik dalam pernikahan.Berbeda dengan Khaled Abou El-Fadl yang menawarkan pendekatan hermeneutikanya melalui metodologi heremeneutikanya dengan menyajikan kerangka konseptual untuk membangun gagasan mengenai sebuah otoritas atau otoritarianisme dalam Islam. Adapun metodologi yang dipakai dalam tulisan ini penelitian ini adalah metode kepustakaan dengan kajian teoritis dari refrensi yang telah dikumpulkan melalui penyesuaian topik yang berkaitan secara konteks budaya, nilai serta norma yang berkembang pada situasi sosial yang diteliti.
