Abstract

Ecosystem Study of Revegetation of Former Mine Land of PT. Semen Indonesia East Java. This study aims to examine understorey species and analyze the importance value index (INP) by measuring vegetation forms including (density, relative density, dominance, relative dominance, frequency and relative frequency) and diversity index (H') in the revegetation area of ex-mining land. PT. Semen Indonesia (Persero) Tbk. The data collection method is observation to obtain primary data from the field. Quantitative data analysis methods include: type, diameter and height of each type of vegetation to determine the importance value index (INP) and diversity index (H'). Research results have found undergrowth consisting of 8 families, 10 genera and 10 species. The types of plants found in the Revegetation Area consist of 3 families and 6 species, including: Tectona grandis Linn. f, Cassia siamea L, Swietenia macrophylla King, Samanea saman (Jacq). Merr, Leucanea leucocephala L, Acacia tomentosa Willd. The species with the highest Importance Value Index (INP) is Tectona grandis Linn f. It can be proven that of all growth phases. The diversity index (H') of all phases belongs to the low category, indicating the ability of a plant species to be unable to adapt well to different environments.
