KAJIAN PERMEABILITAS BEBERAPA JENIS TANAH DI SEI KRIO KECAMATAN SUNGGAL DAN DI PTPN II KECAMATAN TANJUNG MORAWA KABUPATEN DELI SERDANG MELALUI UJI LABORATORIUM DAN LAPANGAN
ABSTRACT: Permeability of the
soil is one important factor indesigning drainage channels. The determination
of soil permeability can be done in the
field and in laboratory. The research was aimed to determine the value of
permeability rate in Sei Krio Alluvial, Entisol, and Ultisol soils in PTPN II
Tanjung Morawa thorugh laboratory and field tests. Results of laboratory
studies showed that the rateof permeability on Alluvial, Entisol, and Ultisol
soils were, 4.39 cm/hour, and 2,14 cm/hour respectively. The value of
permeability rate in the field on Alluvial, Entisol and Ultisol soils were
3.45cm/hour, 4,12 cm/hour, and 2,01 cm/hour respectively. Factoraffecting the
permeability differences between thethree types of soil were effective depth
and porosity of the soil.
Differences in soil
permeability in laboratory
and in the
field were because
of the thickness of the soil.
