The development of learning resources through Benthic species study in mangrove ecosystem Reuleung Leupung for invertebrate zoology learning

This study aimed at developing learning resources through the use of bottom water biota aquatic Mangrove Ecosystem Reuleung, Leupung, and to analyse the composition of biota bottom waters as a source of learning of invertebrate zoology of the students of Undergraduate Program in Biology Education. The research was conducted from July to September 2017 in mangrove ecosystem area of Reuleung Leupung, Indonesia. Two lecturers and three laboratory assistants from Syiah Kuala University and Ar-Raniry Islamic University participated in this study. Data on aquatic biota species as a learning resource was analysed by using percentage formula, while the dominant level of marine biota was analysed by using dominance formula. The results showed that the amount of aquatic biota used ranged from 3.13% to 93.75% and the composition of the use of each species ranged 0.03 to 0.94. It can be concluded that bottom biota which has the highest percentage as learning resource used in study is Moluska Phylum from Class Gastropoda, while Phylum Crustacea from class is widely used in learning is the Malacostraca Class. The composition bottom biota as a learning resource in Invertebrate Zoology learning is low to high.
