Abstract:
This study aims to analyze land suitability in reclamation and revegetation sites for sengon,
trembesi, mahogany and acacia plants. Research was conducted in November 2022 at PT
Adaro Indonesia Site Tanjung, South Kalimantan Province. Data collection was in the form of
analysis of soil quality in the reclamation areas of Wara 1, Wara 2, Wara 3 and Wara 4 and
data on land characteristics as a condition for growing sengon, acacia, trembesi and mahogany
plants, then a matching method was carried out to obtain land suitability for these plant types.
The results showed that the actual land suitability for sengon plants in the entire study area
was incompatible with the inhibiting factors for nutrient retention and quite compatible with
the inhibiting factors for water availability (S3nr.S2wa) and the potential land suitability was
S2nr. Land suitability for acacia plants in all study areas found land that was not suitable for
nutrient retention inhibiting factors (S3nr) and potential land suitability was S2nr. Land
suitability for trembesi plants in Wara 1 and Wara 2 obtained land yields that were not in
accordance with the nutrient retention inhibiting factor (S3nr) and S2nr potential land
suitability, while in the Wara 3 and Wara 4 areas suitable land yields were obtained without
any limiting factors. Land suitability for mahogany plants in all study areas found land that
was not suitable for the limiting factor of nutrient retention and quite suitable for the limiting
factor for water availability (S3nr.S2wa).
