Abstract

Menggunakan metode konvensional, menilai efektivitas pendekatan MI pada menaikkan pemahaman peserta didik terhadap mata pelajaran Fikih, serta mengidentifikasi jenis kecerdasan beragam yg paling mayoritas berkontribusi terhadap peningkatan pemahaman peserta didik pada MTs Istiqlal Medan Marelan. Penelitian ini menggunakan pendekatan kuantitatif menggunakan metode quasi eksperimen serta desain pretest-posttest pada dua gerombolan , yaitu grup eksperimen (menggunakan pembelajaran berbasis MI) serta gerombolan kontrol (metode konvensional). Data penelitian dikumpulkan melalui tes pemahaman siswa pada materi Fikih dan dianalisis secara statistik. yang akan terjadi penelitian menunjukkan bahwa pembelajaran berbasis MI secara signifikan mempertinggi pemahaman siswa dibandingkan metode konvensional, menggunakan nilai rata-homogen posttest kelompok eksperimen (93,65) lebih tinggi daripada gerombolan kontrol (73,70). Uji statistik (thitung = 7,581 > ttabel = 1,682) menegaskan bahwa pendekatan MI efektif dalam meningkatkan pemahaman siswa. Selain itu, akibat observasi mengidentifikasi kecerdasan interpersonal dan kinestetik menjadi jenis kecerdasan yg paling lebih banyak didominasi berkontribusi terhadap peningkatan pemahaman peserta didik. Penelitian ini merekomendasikan penerapan pembelajaran berbasis Multiple Intelligences di madrasah buat mengakomodasi keragaman potensi siswa dan menaikkan efektivitas pembelajaran Fikih.

Abstract

This study aims to analyze the implementation of the washathiyah principle in Islamic business contracts from the perspective of the Qur’an, as well as to identify the obstacles that arise in practice. This research is classified as qualitative library research. The methodology combines a normative–theological approach with conceptual analysis of the washathiyah principle in Islamic business contracts. The findings indicate that the washathiyah principle is reflected in several components of Islamic contracts, such as mechanisms of information transparency, fairness in price determination, and proportional risk-sharing among the parties. Nevertheless, its implementation has not been fully consistent, as it is still influenced by limited sharia literacy, weak ethical business oversight, and the dynamics of the modern market, which often encourage practices that are not aligned with the values of moderation. Therefore, strengthening sharia education, improving the quality of regulation, and internalizing washathiyah values are essential steps toward realizing more just and sustainable Islamic business contracts.

Abstract

Liquid smoke has been widely applied in various fields. Several studies have developed methods, tools and materials for making liquid smoke. This research aims to design a tool for making liquid smoke using a simple pyrolysis method on a laboratory scale. The goal is that this tool can be used by students for practicums to further increase students' insight and skills regarding liquid smoke. The stages of this research start from literature study, technology design, tool fabrication and testing as well as the evaluation stage. The results obtained in this research are that a liquid smoke pyrolysis device has been successfully made with a capacity of 6 kg. Based on the test results, grade 3 liquid smoke was produced.

Abstract

Background/problems: Biodiesel from animal fats is vulnerable to metal-catalyzed oxidation that degrades fuel quality because of the unsaturated fatty acid content. This study investigates the oxidative stability and physicochemical changes of chicken fat and its biodiesel upon FeCl₃-catalyzed oxidation. Methods: Chicken fat was transesterified to produce biodiesel; chicken fat (CF) and chicken-fat biodiesel (CF-BD) were then subjected to an FeCl₃ oxidative condition. Acid value (AV), iodine value (IV), peroxide value (PV), kinematic viscosity at 40 °C, and density were determined using standard titrimetric and physical methods; FTIR assessed spectral changes. ANOVA compared group means. Findings: Oxidation significantly increased AV and PV for both matrices, with a marked PV rise in CF-BD (6.17 ± 0.29 to 88.17 ± 5.35 meq/kg), and decreased IV (CF-BD 84.3 ± 4.51 to 48.7 ± 4.32 g I₂/100 g). Viscosity and density increased modestly. Visually, CF-BD shifted from clear yellow-green to brown and turbid with sediment, consistent with polymer formation and methyl-ester degradation. FTIR showed attenuation/shift of ester carbonyl and aliphatic bands. Conclusion: FeCl₃-induced oxidation measurably deteriorates CF-BD quality, breaching key limits in ASTM/SNI for acid value and viscosity. Impact: Results underscore the need to control trace metals and apply antioxidant/metal-deactivator strategies in storage and distribution, and validate the FeCl₃ assay as a practical accelerated-degradation model for stability and additive screening.
