PERUBAHAN SIFAT FISIK GAMBUT AKIBAT KEBAKARAN DI DESA TELUK BINJAI KECAMATAN TELUK MERANTI KABUPATEN PELALAWAN
Abstract: This research is
conducted to compare the physical characteristic change between burnt & unburnt
peat soil and also to understand its change on both seven days & four
months after burn. This research is held in “Teluk Binjai Village, District
ofTeluk Meranti, Regency ofPelalawan” and its physical analysis is held at Soil
Science Lab of Riau University Agricultural Faculty on January until June 2014.
Moreover, it uses survey method to determine its location and purposive
sampling for sampling method. Both peat soil sampling & field observation
are done twice. First sampling is conducted on seven days after burn and the
second sampling is done four months later (after burn). Its data analyzed by
using descriptive statistic and presented on tables & graphs. In addition,
the observed parameters are Particle Size Distribution (PSD), water holding-capacity,
Bulk Density (BD), Particle Density (PD), porosity and permeability. The
results show that fire on peat land causes physical characteristic change on
peat soil with the sign of decreasing on water holding-capacity, porosity and
permeability. Meanwhile, both Bulk Density (BD) and Particle Density (PD) are
increasing on the burnt rather than the unburnt one. Physical characteristic
change of peat soil from seven days until four months after burn causes
re-increasing on water holding-capacity, porosity and permeability at the depth
of 10-20 cm. Moreover, there are increasing on fine particle size (88 µm and
106 µm) at the depth of 10-30 cm and increasing on both Bulk Density (BD) &
Particle Density (PD) at the depth of 20-25 cm.
