Abstract

This study aims to determine the level of gastropod diversity in Kandara Rice Fields,. This research is an ecological research with a quantitative approach. This study uses a quadratic transect method and sampling using the purposive sampling method. The gatropoda found were Pomacea canalicuta, Melanoides tuberculata, Achatina fulicia, which consisted of 2 orders (Mesogastropoda and Pulmonata), 3 families (Ampullaridae, Thiaridae, and Achatiniadae), 3 genera (Pomacea, Melanoides, and Achatina). The results of the calculation of the ecological index showed that the highest species abundance index was Pomacea canalicuta species with a total of 138 while the lowest species abundance was Achatina fulicia with a number of 12 and a relative abundance of 10.00%, which means it has a low abundance level. The dominance index is 0.50 which means it is in the medium category. The diversity index is 0.81which means the level of diversity is low.

Abstract

The purpose of this research is to know the diversity of plants and the use of plants as learning media in the form of a herbarium. This type of research is a descriptive ecological research with a quantitative approach. Based on the results of the research, it is known that the diversity of herbaceous plants in the Payeti River is classified as moderate with a value of H' = 2.703. Analysis of other ecological indices such as density is known to be the largest density by Digitaria setigera with a relative density value (KR) of 9.54% while the smallest density by Eleocharis geniculate which has a relative density value (KR) of 0.27%, the highest frequency is owned by Digitaria setigera which has a relative frequency value of 11.14% while Eleocharis geniculata has a low frequency species with a relative frequency value of 0.59% and a dominance index of herbaceous plants of 0.071 which is relatively low. The diversity of herbaceous plants was used as a learning medium in the form of a herbarium which obtained an average validation value of 95.06 and was classified as very valid.
