Potential of Dipterocarpus retusus Blume Species in Situ Gunung Forest, Sukabumi. Titi Kalima and Marfu'ah Wardani. Analysis of the potential of Dipterocarpus retusus Blume species in Situ Gunung forest, Sukabumi, West Java, carried out in 2010 in a village location Kadudampit, Kadudampit districts, with the goal of uncovering potential and habitat conditions D. retusus in Situ Gunung forest. Data collection using the Systematic Sampling Strip with units such examples observation of 50 m x 20 m. The results showed that D. retusus recorded five induvidu stems of tree, the saplings (four individu) and seedlings (11 individu) at an altitude of 864-865 m above sea level, slope of 45%, and the soil pH from 6.0 to 6.9. The potential of D. retusus diameter rods >10 cm are 50 stems per ha with 35,061 volume m3/ha. The level distribution D. retusus low, grow clustered and sparse. Abundance values for trees 2.50 stems/ha, 2.00 stems/ha for sapling and 2.20 seedling/ha.
