Since 1990s, the conversion of peatlands in Central Kalimantan from forest land cover and shrubs to
agricultural land can cause the change of the characteristics of the peat. For this reason, this research
on the condition of peat properties is needed, especially the physical properties as a reference material
in the management of sustainable peatlands. This study was aims to determine the characteristics of
peat under several land cover in the transition peat and the inland peat as well as the relationship
between the parameters. The research was conducted in September - December 2017, where located in
West Kanamit Village, Maliku Subdistrict and Taruna Jaya Village, Jabiren Raya Subdistrict, Pulang
Pisau Regency, Central Kalimantan Province. The laboratory analysis at the Laboratory of Agronomy
and the Laboratory of Analytical, University of Palangka Raya. Sampling in this study was uses a
profile with the size of one m2
. This study was uses regression analysis and correlation methods that
are conducted to determine the pattern of relationships and the relationship between the variables of
the physical properties of the peat. The results of the study indicate there is a similarity in the physical
properties of the transition peat of West Kanamit Village and the inland peat of Taruna Jaya Village.
The level of decomposition of peat from all locations was sapric with black to reddish black color. The
average values of the peat in West Kanamit Village are bulk density (0.09-0.18 g cm-3), water content
(451.52-1,013.18%), fiber content (7.62-14.60%), ash content (1.73-26.15%), and organic C (42.83-
57.00%). The results of the study in Taruna Jaya Village had the average values as follows as bulk
density (0.10-0.17 g cm-3), moisture content (361.79-846.99%), fiber content (7.62-14.60 %), ash
content (0.84-2.69%), and organic C (56.44-57.52%). Hydrophobicity in all study locations were 1.1-
3.4 seconds with the WDPT method and the ratio of 0.06-0.49 with the FTIR methods. Moreover, the
relationship between the peat characteristics shows a positive relationship and a negative relationship.
