Abstract


ABSTRAK

Trikloroetilen (TCE) adalah pelarut organik yang sering digunakan dalam proses industri. TCE adalah salah satu contoh dari Non Aqueous Phase Liquid (NAPL) yang sudah banyak mencemari tanah dan air tanah. Tujuan penelitian ini adalah untuk mengetahui sifat-sifat pergerakan TCE dalam berbagai jenis tanah yang berbeda, mengkaji sifat-sifat pergerakan TCE dalam tanah dengan menggunakan kecepatan 1 dan 25 Gravitasi, dan mengetahui faktor-faktor yang mempengaruhi pergerakan TCE dalam tanah. Sifat pergerakan TCE dalam tanah riolit dan granit adalah TCE akan masuk langsung secara vertikal dan horizontal dalam tanah hingga ke dasar tanah. Pergerakan TCE akan terhambat pada tanah yang banyak mengandung partikel berukuran kecil. Pergerakan TCE secara vertikal pada gaya 1G dan 25G dalam tanah granit adalah paling cepat berbanding dalam tanah riolit. Pergerakan TCE dalam tanah kering dipengaruhi oleh sifat tanah terutama ukuran butir dan Kapasitas Pertukaran Kation (KPK).


ABSTRACT

Tricholoroethylene (TCE) is an organic solvent used in many industrial processes. TCE is one of Non-Aqueous Phase Liquid (NAPL) which has already contaminated soil and groundwater. The objectives of this study are to determine the migration of TCE in rhyolite and granite soil, to determine the migration of TCE in soil using 1 and 25 Gravity (G) force, and to determine the migration of TCE influencing factors in the soil. The characteristics of TCE migration in rhyolite and granite soil will migrate vertically and laterally to the bottom of the ground. The migration will be retarded in small particle size of soil. The fastest migration of TCE at 1G and 25G was found in the granite soil. The migration of TCE in dry soil is affected by properties of soil particularly particle size and cation exchange capacity.
