Abstract

Penelitian ini bertujuan untuk mengevaluasi efektivitas starter organik dalam pembuatan pupuk organik padat dari limbah sayur, daun, kulit kopi, dan limbah rumah tangga. Tiga perlakuan yang diuji adalah tanpa starter, starter DLH, dan starter EM4, untuk memantau perubahan pH, suhu, dekomposisi, serta kualitas fisik dan kimia pupuk. Proses berlangsung selama 21 hari dengan pengukuran setiap 3 hari menggunakan Rancangan Acak Kelompok (RAK). Hasil penelitian menunjukkan bahwa perlakuan dengan EM4 menghasilkan pH dan suhu yang lebih stabil, tekstur halus, aroma tanah yang khas, serta volume pupuk yang lebih stabil dibandingkan perlakuan lainnya. Starter DLH mempercepat dekomposisi namun menunjukkan fluktuasi pH yang lebih signifikan, sementara perlakuan tanpa starter menunjukkan perubahan yang kurang konsisten. Efektivitas starter organik bergantung pada karakteristik bahan organik yang digunakan. Berdasarkan hasil tersebut, penggunaan starter EM4 direkomendasikan untuk menghasilkan pupuk organik berkualitas tinggi yang mendukung praktik pertanian berkelanjutan.

Abstract

This study aims to analyze the principle of i’ānah as the ethical foundation for transactions within Islamic banking, utilizing a qualitative approach grounded in literature review and thematic analysis. The principle of i’ānah is conceptualized as the value of mutual assistance, serving as the moral cornerstone for all Islamic economic activities. By employing a qualitative methodology with a library research design and thematic analysis, this research conducts an in-depth examination of i’ānah as the ethical basis for Islamic banking transactions. The findings indicate that i’ānah functions not merely as an ethical guideline but also as a philosophical framework that reinforces the social orientation and justice inherent in Islamic banking transactions. An analysis of various classical and contemporary literature, alongside regulatory documents, demonstrates that integrating i’ānah values into Islamic banking products, services, and governance can enhance ethical compliance, strengthen accountability, and bolster institutional reputation. This study emphasizes the strategic urgency of implementing i’ānah values to fortify moral legitimacy and promote public benefit (maslahah) within Islamic financial practices. These findings pave the way for future research concerning the empirical measurement of i’ānah values regarding institutional behavior and customer perception.
