Abstract

Eco-enzyme represents a biological solution derived from the fermentation of organic materials, evaluated for its effectiveness in industrial wastewater treatment. This study examines  to investigate the effectiveness of eco-enzymes in improving the quality of industrial wastewater by analyzing their impact on four specific types of liquid waste: landfill leachate, tofu wastewater, batik wastewater, and laundry wastewater. Samples were treated with eco-enzyme at specific concentrations and incubated for 5 days, followed by chemical analysis. Eco-enzyme reduced ammonia levels in landfill leachate by 57% to 8.83 mg/L, though COD and BOD values rose to 18,114.6 mg/L and 46,709 mg/L, respectively, exceeding effluent standards. In tofu wastewater, COD and BOD decreased by 72% and 75% to 4,189.68 mg/L and 2,395.3 mg/L, respectively, but remained above regulatory limits. Batik wastewater showed increases in most parameters, with COD and BOD reaching 6,838.85 mg/L and 3,193.5 mg/L. For laundry wastewater, surfactants decreased by 55% to 12.97 mg/L, but BOD and TSS increased. These findings indicate that while eco-enzyme can reduce specific pollutants like ammonia and surfactants, its application can also elevate COD and BOD levels in some cases. Additional treatment processes, such as aeration or coagulation, are required to achieve effluent standards. Despite its limitations, eco-enzyme holds potential as an environmentally friendly option for industrial wastewater management when integrated with complementary technologies.

Abstract

Langkah awal tempat terjadinya partikel plastik yang berukuran 0,3 mm sampai dengan 5 mm disebut mikroplastik dapat masuk ke badan air melalui Tempat Pemrosesan Akhir (TPA) terutama pada proses pengolahan air lindi. Untuk mencegah terjadinya pencemaran mikroplastik pada badan air, perlunya menganalisis dan mengidentifikasi mikroplastik pada air lindi di TPA Talang Gulo Kota Jambi sistem open dumping dan sanitary landfill. Pengambilan sampel pada inlet dan outlet. Tahapan penelitian meliputi penyaringan partikel, pengeringan sampel, pemisahan dengan senyawa organik, dan penyaringan supernatan yang mengandung mikroplastik. Identifikasi mikroplastik dilakukan secara visual menggunakan mikroskop digital, sedangkan identifikasi jenis polimer plastik ditentukan dengan uji streptoskopi inframerah transformasi Fourier (FTIR). Data dianalisis secara kuantitatif, deskriptif dan inferensial untuk membandingkan rata-rata kelimpahan mikroplastik dengan menggunakan uji ­t-paired dan corelations dari air lindi. Kelimpahan mikroplastik yang ditemukan di inlet sebesar 2 partikel/L. Sedangkan pada outlet sebesar 1 partikel/L. Berdasarkan identifikasi ditemukanya tiga bentuk mikroplastik seperti film 16%, fragment 17% dan fiber 67%. Sedangkan, untuk jenis polimer mikroplastik yang ditemukan Polystyrene (PS) dan Nylon Polyamides. Penurunan kelimpahan mikroplastik pada air lindi sebesar 10% sebelum dibuang ke badan air. Peningkatan proses pengolahan air lindi di TPA Talang Gulo perlu dilakukan sebelum dibuang ke badan air guna mencegah terjadinya pencemaran.
