Hakim, ArifRahman (2014) Indikasi Penyebaran Kontaminan Sampah Bawah Permukaan Dengan Menggunakan Metode Magnetik (Studi Kasus: TPA Supit Urang, Malang). Magister thesis, Universitas Brawijaya.
Abstract
Telah dilakukan penelitian mengenai kontaminan sampah di TPA Supit Urang untuk mengetahui keberadaan dan pola penyebarannya. Penelitian ini dilakukan dengan menganalisis data magnetik yang diperoleh di lapangan yang melingkupi daerah sekitar TPA yang jaraknya dekat dengan pemukiman warga dengan jarak antar titik pengukuran sebesar 10 meter. Penelitian dimulai dengan melakukan koreksi data yang meliputi koreksi diurnal dan koreksi IGRF sehingga diperoleh nilai anomali magnetik total daerah penelitian yang berkisar antar -1150 nT sampai 400 nT. Selanjutnya dilakukan reduksi ke kutub dan kontinuasi ke atas sehingga diperoleh nilai anomali magnetik sisa yang berkisar antara -800 nT sampai 1100 nT. Berdasarkan hasil pengolahan data menunjukkan bahwa kontaminan dapat ditentukan berdasarkan batuan pembawanya yaitu batu pasir. Kontaminan sampah yang terdapat di TPA ini diduga berupa lindi dengan nilai suseptibilitas antara 0.0001 Wb/Am sampai 0.001Wb/Am. Dari hasil penelitian, diketahui bahwa lindi di TPA cenderung terakumulasi di bagian dalam TPA, kemudian menyebar hampir ke segala arah menuju topografi yang lebih rendah. Leachate yang terakumulasi di bagian dalam cenderung merembes ke arah selatan karena daerah tersebut merupakan jalur pembuangan lindi dari TPA menuju sungai yang berada di sebelah selatan TPA. Leachate ini terdeteksi hingga kedalaman 25 meter dan diperkirakan dapat merembes lebih dalam lagi. Selain itu, berdasarkan hasil penelitian dapat diketahui bahwa lapisan struktur bawah permukaan TPA Supit Urang didominasi oleh batuan sedimen seperti batu pasir, lempung, tufa, tufa breksi dan breksi.
English Abstract
re has been conducted a research about contaminant in Supit Urang garbage disposal area to identify presence and distribution pattern of contaminant. This research was conducted by analyzing magnetic data gotten from field which consists of inside, north, south and east parts of garbage disposal area located near residence with 10 m gap of measurement spots. This research was begun by doing a data correction, consists of diurnal correction and IGRF correction so that researcher got total magnetic anomaly value of research area which ranges between -1150 nT to 400 nT. n, researcher did reduction to pole and upward continuation so that he got remaining magnetic anomaly value ranging from -800 nT to 1100 nT. Based on result of data processing, it showed that could be determined based on carrier stone which was sandstone. Contaminants garbage contained in landfill suspected is leachate with susceptibility values between 0.0001 Wb/Am to 0.001 Wb/Am. Based on research, it was shown that leachate in garbage disposal area tended to be accumulated inside garbage disposal area, n spread almost everywhere to lower topography. leachate which was accumulated inside tended to leak south because that area was leachate disposal track from garbage disposal area to river on south of disposal area. leak of leachate was detected up to 25 m in depth and predicted to leak deeper. Moreover, based on research results, it was identified that underground layer structure of garbage disposal area was dominated by sedimentary stones, such as sandstones, clays, tuffs, breccial tuffs and breccias.
