https://doi.org/10.26418/pf.v9i2.49494Abstract
Penelitian ini dilakukan dengan tujuan mengetahui nilai sifat fisika tanah gambut di daerah sekitar TPA Batu Layang Pontianak, Kecamatan Pontianak Utara, Kota Pontianak. Data yang digunakan dalam penelitian ini adalah sampel tanah gambut berjumlah 10 sampel dilihat berdasarkan warnanya yaitu tanah gambut jenis hemik dan fibrik dengan pengeboran hingga kedalaman 5 m. Parameter yang diuji di laboratorium terdiri dari: bobot isi, porositas, permeabilitas dan konduktivitas. Hasil uji laboratorium menunjukan tanah gambut di TP1 dan TP3 jenis hemik memiliki bobot isi sebesar 0,21 g/cm3, 0,21 g/cm3, dengan porositas sebesar 86,27 %, 87,74 %, serta permeabilitas sebesar 2.97×10-5m/s, 6.01×10-5m/s dan konduktivitas sebesar 0.062 s/m, 0.156 s/m. Tanah gambut di TP1, TP2, dan TP3 memiliki sifat fisika jenis fibrik dengan bobot isi sebesar 0,16 g/cm3, 0,31 g/cm3, 0,18 g/cm3, serta porositas sebesar 92,92 %, 83,43%, 91,85, permeabilitas sebesar 7.05×10-5 m/s, 3.43×10-5 m/s, 8.31×10-5 m/s dan konduktivitas sebesar 0.025 s/m, 0.050 s/m, 0.200 s/m.
Kata kunci: Jenis Tanah Gambut, Sifat Fisika Tanah.
