Abstract

Mollusca is a soft-boned animal (from the Latin molluscus, soft), and largely secretes a hard protective shell made of calcium carbonate. Mollusca plays a very important role in this life. Some species of this phylum become a source of protein for humans, as an environmental bioindicator. In addition, Mollusca can be a pest for agriculture. The objective of the research is to know the diversity and abundance of Mollusca in the rice field area of Sekarputih Village Widodaren District of Ngawi Regency as a module containing Mollusca diversity found around the rice field area. The method used in this research is the cruising method following the pattern of plots of rice fields that have been determined, and sampling using quadrant sample technique. Six species of Mollusca from 4 classes, four species of Gastropoda class were Pilla ampullaceae, Achatina fulica, Sulcospira testudinaria, Tarebia granifera, and 2 species of Pelecypoda class were Pilsbryoconcha exilis, Corbicula javanica. Pilla ampullaceae has a high abundance, while the lowest abundance is the species Corbicula javanica. The validation of the Invertebrate Animals module (Mollusca) indicates that the module that has been prepared has the criterion "Very good" and feasible to use.
