Abstract

Telah dilakukan penelitian yang bertujuan untuk menentukan efektivitas penggunaan metode aerasi, koagulasi biji kelor dan filtrasi dalam penurunan nilai zat besi (Fe) air gambut serta menentukan kualitas air. Sampel air berupa air gambut, diproses dengan menggunakan metode aerasi, koagulasi biji kelor dan filtrasi. Parameter yang diuji meliputi pH dan zat besi (Fe). Kondisi awal air tanah gambut sebelum menggunakan metode aerasi, koagulasi biji kelor dan filtrasi yaitu nilai pH sebesar 3,5, nilai TDS sebesar 38 mg/L, nilai kekeruhan sebesar 4,13 NTU, dan Fe sebesar 0,91 mg/L. Berdasarkan penggunaan metode koagulasi biji kelor untuk semua konsentrasi diketahui nilai parameter pH sebesar 3,5 s.d. 3,9. Hasil filtrasi memiliki nilai pH sebesar 3,6 s.d. 6,2, sehingga terlihat bahwa parameter pH belum memenuhi standar baku mutu. Parameter Fe telah memenuhi kualitas air bersih pada penggunaan metode koagulasi biji kelor dengan efektivitas mencapai 92%. Proses tersebut mampu menurunkan Fe dari 0,91 mg/L menjadi 0,077 mg/L. Penggunaan metode filtrasi tertinggi mencapai 93% berarti mampu menurunkan Fe dari 0,91 mg/L menjadi 0,063 mg/L pada konsentrasi 1/50. Penurunan nilai Fe air gambut efektif dilakukan dengan menggunakan metode aerasi, koagulasi biji kelor dan filtrasi. Kata Kunci: Aerasi, Air Gambut, Filtrasi, Koagulasi Biji Kelor, Zat Besi

Abstract

Islamic business has the phenomenon of being easy to grow and easy to leave. This study aims to analyze the sustainability of Sharia business from the perspective of risk management. This research uses a qualitative approach with a type of literature study employing the PRISMA Method (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Data was collected from various literature, both from books and related journals. This study introduces the Islamic view on risk management, the urgency of risk management for Sharia businesses, and the implementation of Islamic principles that emphasize the blessings and pleasure of Allah SWT in its operations. The main findings of this study indicate that the application of risk management following Sharia principles can enhance the sustainability of Sharia businesses. The practical implications of this study guide for Sharia business practitioners to consistently manage risks, thereby achieving business sustainability. As a result, businesses can endure and provide benefits for economic circulation in the community.
