The island of Java has a wet tropical climate and has a variety of vegetation stands. Each vegetation stand has a composition of species, age, and vegetation density that varies and affects the level of soil fertility. This study examines the analysis of vegetation and soil organic carbon (SOC) characteristics at  forest stands of Mount-Merbabu National Park (Pine (Pinus merkusii), Puspa (Schima noronhae Theaceae), Acacia (Acacia decurren Fabaceae), Bintamin (Cupressus sp), and Mixed) and upland farming at a soil depth of 0-70 cm. Observations of vegetation analysis were made by Observing Plot Units measuring 50 m x 50 m and 3 replicates, while the observations of soil organic carbon included: organic-C and bulk density soil at a depth of 0-70 cm (0-10, 10-20, 20-30, 30-50, and 50-70 cm) and 3 replicates. The research data were analyzed descriptively, followed by the F-Test and DMRT Test at 5% level. The results obtained: (a) the forest stands of Mount-Merbabu National Park has the highest important value index in Puspa (Schima noronhae Theaceae) forest stand, followed by Pine (Pinus merkusii), Acacia (Acacia decurren Fabaceae), Bintamin (Cupressus sp), and Mixed; (b) the content of SOC decreased with increasing soil depth (0-10, 10-20, 20-30, 30-50, 50-70 cm). At soil depth (0-70 cm) the highest of SOC content was in the Puspa (Schima noronhae Theaceae) forest stand (5.34%), followed by Mixed (5.00%), Bintamin (Cupressus sp) (2.81%), Acacia (Acacia decurren Fabaceae) (2.44%), and the lowest is Pine (Pinus merkusii) (2.01%); while the upland farming (1.53%). Puspa (Schima noronhae Theaceae) can be recommended as a good type of revegetate plant (reforestation).
