Abstract

Produksi sampah yang semakin tinggi khususnya di perkotaan, dipicu dengan adanya proses modernisasi dan pembangunan segala bidang yang akhirnya menyebabkan terakumulasinya sampah sehingga semakin hari semakin menumpuk. Air lindi (leachate) adalah air hasil degradasi dari sampah dan dapat menimbulkan pencemaran apabila tidak dilakukan pengolahan terlebih dahulu sebelum dibuang ke lingkungan. Penggunaan metode open dumping di banyak TPA Indonesia belum memiliki fasilitas perlindungan lingkungan hidup yang memadai, yang mana produk sampingan yang dihasilkan dari kegiatan penimbunan, yaitu gas dan air lindi (leachate) akan terakumulasi dan mengakibatkan pencemaran di suatu waktu, baik saat masih berjalannya proses pengelolaan ataupun pasca kegiatan.
Kualitas air tanah di sekitar wilayah bekas TPA Keputih telah mengalami pencemaran. Air tanah ini belum memenuhi standar baku mutu Permenkes RI No.32 Tahun 2017 tentang Standar Baku Mutu Kesehatan Lingkungan dan Persyaratan Kesehatan Air untuk Keperluan Higiene Sanitasi, Kolam Renang, Solus Per Aqua, dan Pemandian Umum. Parameter yang tercemar antara lain; TDS (1630 mg/L), kekeruhan (29,4 NTU), warna (173,7 Unit PtCo), Fe (2,01 mg/L), Mn (0,76 mg/L), kesadahan total (621,43 mg/L), deterjen (1,27 mg/L) dan zat organik (11,4 mg/L). Salah satu alternatif teknologi remediasi air tanah tercemar air lindi dapat menggunakan media filter pasir silika dan filter karbon aktif. Pemilihan alternatif teknologi remediasi ini mengacu pada matriks scoring dengan nilai aspek pemeliharaan dan perawatan, investasi modal, efisiensi pengolahan, biaya operasional, waktu pemulihan air tanah dan kebutuhan tenaga ahli. Perencanaan awal teknologi remediasi ini dilakukan dengan menentukan kapasitas pengolahan dengan proyeksi kebutuhan air bersih 120% dari kebutuhan air rata-rata. Teknologi remediasi yang dirancang memiliki kapasitas sebesar 8.930 L/hari. Desain teknologi yang direncanakan yaitu ; pompa sumur dangkal, unit filter pasir silika, unit filter karbon aktif dan tandon air dilengkapi dengan pompa Backwash. Proses remediasi dilakukan dalam 3 cycle per hari. Waktu setiap cycle selama 8 jam, dengan waktu proses remediasi 80 menit. Debit yang mengalir tiap cycle sebesar 2.970 L/cycle. SOP yang disusun yaitu SOP Operasional Teknologi, SOP Pemeliharaan dan Perawatan (Pembubuhan Kaporit Tablet, Backwash dan Pembuangan Endapan). Biaya yang direncanakan dari teknologi remediasi ini sebesar Rp.28.000.000

The increase of solid waste generation especially in urban areas, prompted by modernization and holistic development of all fields, have led to solid waste accumulation, resulting in the piling up of solid waste as each day passes. Leachate is water produced from waste degradation that possesses the potential to contaminate the environment if not properly treated ahead of disposal. The operation of open dumping method in many landfills in Indonesia has not met the appropriate environmental protection facility standards, in which case gas and leachate as the byproduct of landfilling activities, will accumulate and eventually pollute the environment, whether in the timeframe of its treatment or post-treatment. The groundwater quality in the area of ex-TPA Keputih is contaminated. The groundwater quality exceeds the quality standard set by Permenkes RI No.32 Tahun 2017 tentang Standar Baku Mutu Kesehatan Lingkungan dan Persyaratan Kesehatan Air untuk Keperluan Higiene Sanitasi, Kolam Renang, Solus Per Aqua, dan Pemandian Umum. The parameters that exceed the quality standards are as follows: TDS (1630 mg/L), turbidity (29,4 NTU), colour (173,7 Unit PtCo), Fe (2,01 mg/L), Mn (0,76 mg/L),total hardness (621,43 mg/L), detergents (1,27 mg/L) and organic matter (11,4 mg/L). One of many remediation technology alternatives for leachate-contaminated groundwater is quartz sand, gravel and activated carbon, treats contaminated groundwater through adsorption and filtration. This selection of remediation technology is based on its high score in matrix of operation and maintenance, capital cost, treatment efficiency, operational cost, water treatment media recovery speed, and labour of expertise needs. The initial design step of this remediation technology is carried out by determining the treatment capacity by projecting 120% of the average water demand. This remediation technology has a capacity of 8,930 L/day. The technology designs are as follows: Shallow Sump Pump, silica sand filter unit, activated carbon filter unit, and Water storage tank equipped with Backwash Pump. The remediation process is conducted in 3 cycles per day. The duration of each cycle is 8 hours, with remediation process of 80 minutes. Each cycle operates with a flowrate of 2.970 L/cycle. The Standard Operation Procedures that are composed are the following: Operational Technology SOP, Operation & Maintenance SOP (Tablet Caporite Feeding, Backwash and Sedimentation Disposal). The estimated cost of this remediation technology is Rp. 28.000.000
