【 摘 要 】

Pitcher plants (Nepenthes sp.) is a plant with unique shape either of shades of colors, pouch shape and its capability in catching insects. Pitcher plant (Nepenthes sp.) is one of the plants that protected under Law Number. 5 of 1990 about Conservation of Biological Resources and Ecosystem and Government Regulation Number 7/1999 about Preservation of Plants and Animals. Sebangau National Park is one of representative of peat swamp ecosystem and one of some types of pitcher plants (Nepenthes sp.) habitat. This study aimed to determine the types and diversity levels of pitcher plants (Nepenthes sp.) and the trapped insects inside in Sebangau National and to determine the differences of diversity levels of pitcher plants (Nepenthes sp.) and the trapped insects inside in the opened and closed forest in Sebangau National Park. The research type was conducted descriptive qualitative research. The method used survey method with purpossive sampling technique.The result of the study the number of pitcher plants (Nepenthes sp.) obtained in opened forest were three types consist of Nepenthes mirabilis, Nepenthes rafflesiana and Nepenthes gracilis with two types insects trapped inside those were Diptera ordo and Hymenoptera ordo. While the number of pitcher plants (Nepenthes sp.) obtained in closed forest as many as two types consist of Nepenthes ampullaria and Nepenthes rafflesiana with two type insects trapped inside those were Diptera ordo and Hymenoptera ordo. The results of the analysis calculation pitcher plants (Nepenthes sp.) species diversity index in opened and closed forest showed lower category. The diversity in row were 1 and 0,45 with H' criteria ≤ 1 low diversity. The results of the study of insects trapped inside of pitcher plants (Nepenthes sp.) obtained in opened and closed forest showed low category. The diversity in a row were 0,63 and 0,52 with the criteria of H' ≤ 1 low diversity.
