Abstract

Tempat Pemrosesan Akhir (TPA) Keputih di Kota Surabaya beroperasi pada tahun 1970-2001. Problematika utama yang muncul dari aktivitas di TPA Keputih adalah pembentukan lindi. Pada tahun 2001 pasca penutupan TPA Keputih, ditemukan lindi pada beberapa titik di sekitar lokasi. Penelitian ini bertujuan untuk mengetahui penyebaran lindi di TPA Keputih pasca penutupan dan pengaruhnya terhadap kualitas air tanah dangkal di sekitarnya.

Pada penelitian ini dilakukan analisis penyebaran lindi. Metode yang digunakan untuk penelitian ini yaitu metode Active Directory Magnetotelluric (ADMT) untuk memperoleh variasi impedansi setiap lapisan batuan di bawah permukaan tanah. Selain itu dilakukan pengambilan sampel air tanah dangkal di tiga titik yaitu sumur warga, kolam pantau TPA dan waduk di sekitar area TPA Keputih untuk menganalisis kandungan lindi. Pengolahan data menggunakan Software AIDU Prospecting, Surfer dan Voxler dan analisis konduktivitas hidrolik menggunakan persamaan empiris.

Hasil penelitian menunjukkan nilai konduktivitas hidrolik pada TPA termasuk pada klasifikasi tinggi dengan material pasir, pasir dan kerikil, dan lempung berpasir. Pola sebaran arah aliran air atau lindi menuju ke arah timur (laut). Penyebaran lindi dipastikan masih terjadi pada air tanah dangkal di lokasi TPA. Hal ini ditunjukkan oleh nilai BOD5, COD dan TSS yang melampaui baku mutu lingkungan untuk lindi.

The Keputih Landfill (TPA) in Surabaya City operated from 1970 to 2001. The problem appearing from activities at the Keputih landfill, there was found leachate. In 2001 after the Keputih landfill was closed, leachate was found at several points around the location. This study aims to determine the distribution pattern of leachate at the Keputih landfill after closure and its impact on the quality of the surrounding groundwater.

In this research, analysis of leachate distribution was carried out. The method used for this research is Active Directory Magnetotelluric (ADMT) to obtain the variation in the impedance of each layer of rock below ground surface. In addition, shallow groundwater samples were taken at three points, namely residents wells, TPA monitoring ponds and reservoirs around the Keputih TPA area to analyze leachate content. Data processing was carried out with AIDU Prospecting Software, surfer software, voxler software and hydraulic conductivity analysis using empirical equations.

The research results show that the hydraulic conductivity value at the landfill is included in the high classification with sand, sand and gravel, and sandy clay materials. The distribution pattern of water or leachate flow is towards the east (sea). The spread of leachate is confirmed to still occur in shallow groundwater at the landfill location. This is indicated by the BOD5, COD and TSS values exceeding the environmental quality standard for leachate.
