Upaya Meningkatkan Stabilisasi Pada Tanah Bekas Timbunan Sampah Dengan Penambahan Bahan Kapur
Keywords:
Stabilisasi, Tempat Pembuangan Sampah, KapurAbstract
Sampah yang dihasilkan oleh aktifitas manusia baik yang berasal dari limbah industri maupun limbah rumah tangga dibuang dan terkumpul di satu wilayah tertentu yang biasa disebut tempat pembuangan sampah. Adanya sampah yang tertumpuk di Tempat Pembuangan sampah selama bertahun-tahun dengan volume yang cukup besar akan menghasilkan air rembesan sampah (leachate) yang mengandung unsur kimiawi serta bahan organik yang merupakan hasil dekomposisi sampah organik akan mempengaruhi kualitas tanah yang ada dibawahnya. Untuk meningkatkan stabilisasi tanah perlu dilakukan perbaikan dengan metode pencampuran bahan lain sebagai langkah perbaikan sifat-sifat fisik tanah. Pada penelitian ini dilakukan perbaikan tanah dengan menambahkan
bahan kapur dengan variasi 0%, 5%, 10%, 15%, dan 20%. Pada masing-masing variasi dilakukan pemeraman antara 0 hari, 7 hari, 10 hari dan 14 hari. Pengujian sifat fisik antar lain kadar air, batas cair (LL), batas plastis (PL), batas susut (SL), dan specific gravity, direct shear. Semakin tinggi kadar kapur akan menurunkan prosentase kadar air, nilai batas cair, nilai batas plastis, indek plastisitas namun akan menaikkan nilai spesific gravity. Dari pengujian direct shear nilai optimum didapatkan terjadi pada kadar kapur 15% yang terjadi pada semua kondisi pemeraman.
