Abstract

This research has been conducted with the tittle the diversity of gastropods on the river water environment Empayang Lahat regency of South Sumatra province. The aim of this research species diversity of gastropods contained the region. This research was implemented conducted in October 2015, a river Empayang Kasap Sukajadi Lahat regency. The methods of this research is purposive random sampling method with 5 sampling stations, each station is divided into three substations (edges first, middle, edge 2) was determined by linear transects (line transect). The data of the sample was taken in the morning and afternoon. The results of this research were obtained 8 species of gastropods (Melanoides granifera, Elimia acuta, Brotia tetidinaria, Lymnae stagnalist, Lymnae rubiginosa, Pomacea canaliculata, Pila polita and Menetus sp) with 7 genus, and of the six tribes (families) of 4 order. The total index of the diversity in the river Empayang Kasap Sukajadi Lahat district was of 2.09 to 2.46. The highest levels of diversity found in the station V (2.46) and the lowest at station I (2.09). While the value of dominance index (C) with a range of 0.17 to 0.26 at five stations in the lower state, the highest level of dominance index at station I (0.26) and the lowest at station III (0.17). River water quality conditions greatly affect the existence of gastropods.

Abstract

Odonata are considered to be good indicators of enviromental health and water quality with it’s presence and diversity in the Jakabaring lake are (Water Ski and OPI). The research location (Water Ski and OPI) untilized by the community as water catchment areas (flood control), recreation and habitat. The Activity in the lake area can affect the benefit of the lake, affecting the quality of the lake waters as a living habitat for animals and plants.However, to describe the diversity of odonata as indicator of the waters in the area of Water Ski and Lake OPI lakes, there is no such thing, therefore the researchers to look at odonata diversity in the area of Water Ski Lake and Lake OPI Jakabaring Palembang-South Sumatera. The location of the study was determined using the purposive sampling method conducted in April 2018. The species found to identified at the FMIPA Animal Taxonomy Laboratory of Sriwijaya University. Sampling in the morning (07.00 – 10.00 AM) and afternoon (15.00 – 18.00 AM). The results of research in the lake area found 2 suborder, 2 families, 11 genere, and 18 species, the total number of all 984 individual species. Odonata species data obtained in the analysis using Past3 software. The diversity index in the Water Ski lake is 1.992 and the diversity index in the OPI lake is 1.758. Diversity index value (2.014), dominance index (0.7922) and evenness index (0.4165). Odonata and enviromental conditions of the lake (Water Ski and OPI) still have relationship, the condition of lake water quality is still below water quality criteria threshold. This is what makes the diversity on both lakes has a moderate value.
