PENGARUH AIR LINDI PADA TERHADAP pH DAN ZAT ORGANIK PADA AIR TANAH DI TEMPAT PENAMPUNGAN SEMENTARA KELURAHAN PAHANDUT KOTA PALANGKARAYA (Effect of Leachate to pH and Organic Substances of Ground Water in The Waste Transfer Station in Kelurahan Pahandut Kota Palangka Raya)

Abstract

Abstrak

Tumpukan sampah di Tempat Penampungan Sementara (TPS) maupun Tempat Pemrosesan Akhir (TPA) yang menghasilkan air lindi perlu dilakukan pemantauan untuk mengetahui air lindi sebelum dibuang guna mencegah terjadinya pencemaran air tanah. Penelitian ini bertujuan mengetahui pengaruh dari kualitas air lindi terhadap air tanah warga di sekitar lokasi TPS di Kelurahan Pahandut, Kota Palangka Raya. Penelitian dilakukan dengan melakukan pemeriksaan parameter air lindi, seperti Total Suspended Solid (TSS), Dissolved Oxygen (DO), kandungan minyak dan lemak. Selain itu, parameter kualitas air tanah juga diperiksa, seperti pH dan kadar zat organik pada 2 titik lokasi dengan jarak masing-masing 50 meter. Hasil penelitian menunjukkan bahwa kadar TSS air lindi di sekitar TPS melebihi baku mutu yaitu 130 ppm dan berpotensi sebagai penyebab tercemarnya air tanah di lokasi sekitar TPS tersebut. Kadar zat organik air tanah pada titik 1 dan 2 melebihi baku mutu yaitu sebesar 17 dan 15,1 ppm dari baku mutu yang diharapkan 10 ppm serta pH yang di bawah rentang pH yang diizinkan yaitu 6,5-9.

Abstract

Piles of domestic waste in Temporary waste transfer station (TPS) and Final Processing Station (TPA) that produce leachate need to be monitored to find out the leachate before disposal to prevent contamination of groundwater. This study aims to determine the effect of leachate water quality on groundwater of residents around the TPS location in Pahandut Village, Palangka Raya City. The study was conducted by examining the leachate quality parameters, such as Total Suspended Solid (TSS), Dissolved Oxygen (DO), oil and fat content, and also examining the groundwater quality parameters, such as pH and organic matter at two water samples from two locations of sampling site with a distance of 50 meters. The results showed that the TSS value of leachate was 130 ppm, which exceeded the permitted quality standard. It can lead groundwater pollution in area around the TPS. The organic substance levels of two site of groundwater exceeded the groundwater quality standards, 17 and 15.1 ppm respectively. The pH of two site of groundwater was 6.5-9, which was below the groundwater quality standards.
