Abstract

Lindi kompos mengandung bahan organik, amonia, dan padatan tersuspensi dalam konsentrasi tinggi yang berpotensi mencemari lingkungan apabila tidak dikelola dengan baik. Penelitian ini mengevaluasi efektivitas sistem pengolahan bertahap menggunakan pretreatment zeolit, zeolit alami dan zeolit teraktivasi yang dikombinasikan dengan Tumbuhan fitoremediator kayu apu (Pistia stratiotes) dan enceng gondok (Eichhornia crassipes) dalam menurunkan kadar pencemar lindi yang bersumber dari Rumah Kompos Wonorejo, Surabaya. Penelitian dilakukan pada skala laboratorium menggunakan Rancangan Acak Lengkap (RAL) dengan variabel bebas meliputi jenis zeolit, jenis Tumbuhan fitoremediator, dan waktu kontak hidrolik (12 dan 24 jam). Karakteristik lindi awal sebelum pengolahan tercatat dengan kadar COD sebesar 2.520 mg/L, BOD sebesar 1.249 mg/L, TSS sebesar 340 mg/L, dan amonia sebesar 785,79 mg/L. Pengamatan dilakukan selama 21 hari dengan pengambilan sampel pada hari ke-3, ke-5, ke-7, ke-14, dan ke-21. Hasil penelitian menunjukkan bahwa seluruh variasi perlakuan mampu mereduksi kadar pencemar secara konsisten sepanjang periode pengamatan. Reaktor terbaik adalah kombinasi zeolit teraktivasi dengan waktu kontak 24 jam dan enceng gondok (24-ZA-EG), yang menghasilkan efisiensi removal COD sebesar 87,3%, BOD sebesar 92,0%, TSS sebesar 86,5%, dan amonia sebesar 70,8% pada hari ke-21. Enceng gondok secara konsisten menunjukkan kinerja yang lebih baik dibandingkan kayu apu, sedangkan zeolit teraktivasi menghasilkan effluen yang lebih rendah dibandingkan zeolit alami pada seluruh variasi perlakuan.

Compost leachate contains high concentrations of organic matter, ammonia, and suspended solids, which may cause environmental pollution if not properly managed. This study evaluated the effectiveness of a sequential treatment system consisting of a zeolite pretreatment stage using natural zeolite and activated zeolite combined with phytoremediation plants, namely water lettuce (Pistia stratiotes) and water hyacinth (Eichhornia crassipes), in reducing pollutant concentrations in compost leachate collected from the Wonorejo Compost House, Surabaya. The experiment was conducted at laboratory scale using a Completely Randomized Design (CRD) with independent variables including zeolite type, phytoremediation plant species, and hydraulic retention time (12 and 24 hours). The initial characteristics of the untreated leachate showed COD, BOD, TSS, and ammonia concentrations of 2,520 mg/L, 1,249 mg/L, 340 mg/L, and 785.79 mg/L, respectively. Observations were carried out over a 21-day period with sampling conducted on days 3, 5, 7, 14, and 21.
The results demonstrated that all treatment variations consistently reduced pollutant concentrations throughout the observation period. The best-performing reactor was the combination of activated zeolite with a 24-hour contact time and water hyacinth (24-ZA-EG), which achieved removal efficiencies of 87.3% for COD, 92.0% for BOD, 86.5% for TSS, and 70.8% for ammonia on day 21. Water hyacinth consistently exhibited better treatment performance than water lettuce, while activated zeolite produced lower effluent concentrations than natural zeolite across all treatment variations.
