INDEKS KEANEKARAGAMAN CAPUNG (INSECTA: ODONATA) SEBAGAI PENGUKUR KUALITAS LINGKUNGAN SUNGAI DALAM KAWASAN TAMAN NASIONAL BANTIMURUNG BULUSARAUNG

Abstract

Dragonflies (Insecta: Odonata) has important roles in the ecosystem. They act as a predator, control population,and indicator of environmental pollution. The research objectives are to inventory and calculate the species diversity ofdragonflies in Bantimurung Bulusaraung National Park (Babul NP) region and also measure the environment quality ofrivers according to the Species Diversity Index (SDI). The study was conducted through exploration in the six resorts.Dragonflies specimens will be identified and confirmed to LIPI Cibinong, Bogor, West Java. SDI calculated by theShannon-Wiener formula. The results showed that there are 27 species of Odonata (17 members of the SuborderAnisoptera and 10 of Suborder Zygoptera) in Babul NP region. SDI shows >2.41 means that environmental quality is invery good category. The conclusion of this research was that dragonflies in the Babul NP is very diverse with thediscovery of 27 species in six working area resort.
