Abstract

This research discusses the hadith in Sahih Bukhari that narrates that one of the places of misfortune is women. Textually, this hadith is controversial as it is perceived to contain misogynistic suggestions conveyed by the Prophet Muhammad (peace be upon him). The purpose of this research is to comprehensively understand the process of transmission and the scholars' interpretation of this hadith. Additionally, this research also attempts to interpret the hadith through the contemporary Fiqh al-Hadith methodology proposed by contemporary scholars. The researcher employs a qualitative inductive method, obtaining data and information by collecting classical Islamic texts, including those that specifically explain the related hadith as well as other relevant books. These include books on hadith terminology, hadith commentaries, hadith text, and hadith narrator studies, among others. This research finds that the Sahih Bukhari hadith number 5093 is of hasan quality. This hadith also has many corroborating and supporting narrations of better grades. Meanwhile, the meaning of misfortune contained in it, according to the majority of scholars, is attributed to women temporarily and not permanently. Misfortune is associated with women when they have bad character, infertility, and other non-permanent negative traits. In the mubadalah (reciprocal) method, misfortune is not only attributed to women but also to men, as men can also experience infertility, bad character, and other non-permanent negative traits.

Abstract

This research explores the important role of learning interest in increasing students' understanding of mathematical concepts, especially on the topic of Systems of Linear Equations in Two Variables (SPLDV). Using a quantitative approach and correlational survey method, this research analyzes the relationship between students' learning interest and their understanding of concepts. Data was collected from 94 grade 10 students at Al Falah Vocational School, South Jakarta. The research results show that students who have a high interest in learning have better understanding, with a correlation coefficient of 0.70 and a determination coefficient of 49%. These results show that almost half of the variation in students' SPLDV understanding can be explained by their learning interest. This research also emphasizes the need for innovative teaching methods to increase student engagement and understanding. Implications for educational strategies and future research directions are discussed.

Abstract

This study describes the manufacture of modified composites from recycled HDPE plastic waste and TKKS fibers. The comparison of matrix composition with TKKS fibers used is (70:30); (80:20) and (90:10) %. The mixing process of HDPE with OPEFB was carried out using the melt blending method and extruded to obtain composite pellets. Composite characterization obtained high tensile strength in HDPE composites: OPEFB ratio (70:30) % of 36.50 Mpa, while the tensile strength of HDPE: OPEFB ratio (80:20) and HDPE: OPEFB ratio (90:10) % were obtained respectively 23.50 MPa and 26.50 MPa. The results of the surface structure test with SEM showed that there was a bond between the HDPE matrix and TKKS fibers which was marked by a brittle fracture shape on the surface of the composite and the fibers were not uniformly broken. The impact test results of HDPE composite: OPEFB ratio (80:20) % have a high impact value of 0.363168 Joules. The FT-IR test results show deformation of C-H vibrations and pyranose C-O-C which are typical of OPEFB at wave numbers 1070.49 & 1151.50 cm- and intermolecular O-H bending in TKKS at wave numbers 3672.47 cm-. The TGA test results of HDPE composite: OPEFB ratio (70:30) and HDPE: TKKS (80:20) obtained degradation temperature values (Te) of 535.57ᴼC and 529.74ᴼC, respectively.

Abstract

In the current era of globalization, science and technology are developing rapidly. One example of very popular technology is gadgets. Gadgets have a positive impact on children's thinking patterns, such as helping them regulate the tempo when playing, designing strategies in games, and improving right brain abilities. Notwithstanding these benefits, the use of gadgets can have detrimental effects on children's development, with a heightened impact on teenagers. The radiation produced by gadgets can damage a child's nerve tissue and brain if used too often. More importantly, children become less mobile and are rarely exposed to sunlight, which affects their physical health. As a result, children tend to become less interactive, less creative, and more comfortable being alone with their gadgets. This can trigger individualistic attitudes and reduce feelings of concern for parents, friends and other people around them, as well as their physical health. Physical education and sports carried out in the right proportions can make children fitter, so they can remain active and productive.

Abstract

This study focuses on examining the concept of religious pluralism as contained in Quraish Shihab's monumental work Tafsir Al-Misbah, with particular emphasis on the significance of his thinking in the contemporary Indonesian landscape. As is widely known, Indonesia is a nation with extraordinary diversity in terms of religion and culture, and it constantly faces the challenge of maintaining social cohesion amid the potential for friction between religious communities. Tafsir Al-Misbah presents a perspective that promotes inclusiveness towards religious pluralism, based on the fundamental universal principles contained in the Qur'an, such as justice, empathy, and respect for diversity. This study implements a qualitative methodology through content analysis techniques on relevant arguments in Tafsir Al-Misbah, particularly those related to interfaith interaction. The results of this study show that: First, Quraish Shihab emphasises the importance of understanding pluralism as sunnatullah (God's decree) and the basis for creating a mutually respectful society. Second, Quraish Shihab's contextual interpretation refers to Indonesia's experience as a multireligious nation.

Abstract

Biomaterial adalah material yang digunakan untuk mengganti struktur biologis yang hilang atau sakit. Material ini harus dapat diterima oleh tubuh. Salah satu biomaterial yang paling banyak digunakan untuk aplikasi bone plate adalah stainless steel 316L. Saat diaplikasikan pada tubuh pasien, material ini akan mendapatkan beban sejajar permukaan. Beban ini merupakan beban yang cukup dominan diterima oleh bone plate stainless steel 316L. Beban yang diterima bone plate stainless steel 316L akan berubah dan bervariasi. Sehingga perlu dilakukan simulasi tegangan degan memberikan gaya tekan pada bone plate stainless steel 316L. Simulasi tegangan dilakukan dengan menggambar dan menganalisis tegangan dengan menggunakan Autodesk Fusion 360. Selanjutnya material tersebut diberikan beban berupa static load mulai dari 150 N sampai 2300 N. Hasil analisis tegangan menunjukkan distribusi tegangan terdapat ditengah dan ujung bone plate. Regangan dan perubahan bentuk menunjukkan peningkatan seiring dengan kenaikan nilai tegangan. Gaya tekan 150 N sampai 600 N merupakan beban yang aman karena masih dibawah titik luluh 170 MPa. Gaya tekan 700 N sampai 2300 N merupakan beban yang tidak aman karena sudah melebihi titik luluhnya. Hal ini akan menyebabkan material mengalami deformasi plastis dan patah.
