ABSTRACT The purpose of this study to determine diversity of Kantong Semar (Nepenthes spp) and level of dominance. Determination of observation using purposive sampling method with plot size of 40 mx 40 m. In the region there are 3 types of Nepenthes spp, among other Nepenthes ampullaria, Nepenthes xhookeriana, and Nepenthes rafflesiana. The most dominant type is Nepenthes ampullaria with value (INP = 105.57%), followed by Nepenthes xhookeriana with (INP = 71.60%), lowest type of Nepenthes rafflesiana with (INP = 22.83%). The dominant species is Nepenthes ampullaria with highest dominance value (C = 0.2786), While lowest is the Nepenthes rafflesiana (C = 0.0130). The highest diversity index Nepenthes xhookeriana namely (H '= 0.1597) and type of Nepenthes ampullaria (H' = 0.1465), while lowest diversity index for the types of Nepenthes rafflesiana (H '= 0.1076). The value of highest abundance of Nepenthes spp was Nepenthes xhookeriana with an abundance of types of 0.3347 and lowest abundance found in Nepenthes rafflesiana kind of 0.2255.
