Abstract

The Palak Siring Waterfall is a natural tourism object located in Kemumu Village, Armajaya District, North Bengkulu Regency were the area have variety of vegetation. This research aims to analyze the Terrestrial Fern Diversity in that area. The benefits of ferns in an ecosystem are as one of the pioneer organisms that open and start a new life in an ecosystem, food sources, and planting media. The method used is transect by forming (five) plots based on the slope of the land, consist of flat, sloping, rather steep, steep, and very steep areas. Plot size of 20 x 20 m placed along the transect line. Based on the survey was found 22 species with 13 types of family ferns in the Palak Siring Waterfall. The Diversity Index value of ferns (pteridophyta) belongs to the medium category. This certainly indicates that there is a fern that can adapt to the environment as well as other plants in area. Diversity of fern have the potential to be applied to junior high school science learning through several Basic competencies, materials, and forms of learning activities.

Abstract

This research aims to identify the abundance, diversity, dominance and evenness of gastropods at the mouth of the Ketahun River, North Bengkulu. The method used is the "purposive" method. The sampling location was divided into 4 (four) stations, namely in the tidal area and on the right and left in the downstream part of the estuary. The sampling technique uses transects, at each station measuring 20m. Gastropod data analysis uses the Shannon Wiener index, Simpson index, and Pielou index. The research results showed that at the mouth of the Ketahun river, 18 species of gastropods were obtained consisting of 7 genera and 3 families. The diversity index shows, a) station I has an index value of 1.81 (medium category); b) station II has an index value of 0.49 (low category); c) station III has an index value of 1.89 (medium category); d) station IV has an index value of 0.82 (low category). The dominance index shows, a) station I has an index value of 0.23 (low category); b) station II has an index value of 0.70 (medium category); c) station III has an index value of 0.19 (low category); d) station IV has an index value of 0.63 (medium category). The evenness index shows, a) station I has an index value of 0.62 (high category); b) station II has an index value of 0.17 (small category); c) station III has an index value of 0.65 (high category); d) station IV has an index value of 0.28 (small category). The most common gastropod found is the genus Clithon with a total of 1369 individuals. Abundance, diversity, dominance and evenness are determined by abiotic parameters and environmental conditions such as substrate and water quality. Keywords: Bengkulu, Gastropods, Ketahun River
