Abstract

Some region in East Java is known as biota producer that almost a along time produce a such as snail and mollusk. One of region in East Java which be known as snail and mollusk (mollusca) of sea in big quantity is Situbondo region. One of district in this region from Situbondo regency are Bungatan district where this region have one of village, namely Bungatan village. Setting of this district about 26.9 km from city center, with area 66.70 km. Expansion of this area is proposed in order writer will be easy to carry out study to inventory or collect samples from Gastropoda. The goal of this study is to see mollusca kind, (class gastropoda) what everything contain in coastal Bungatan village based on the low ebb up to maximal boundary along with how density degree, frequent and important value index of mollusca (class gastropoda) in coastal of Bungatan village, Bungatan District Situbondo regency. The study method is descriptive method. Study location and time is carried out in coastal ebb region of Bungatan village Bungatan district Situbondo regency, it was started 3 up to 10 May 2007. The population of this study are all of gastropoda class in coastal of Bungatan village by 1000 m area or 1 ha and the samples of this study are gastropoda class which contain in observation plot in 600 m or 0.06 ha. In this study, the data which be gained from observation result with three steps: step to determine location of samples study, step of samples taking, step of samples identifying. Based on the observation result which have been gained, ant then it is analyzed by follow formula: absolute density (Di = total of individual/total wide of sampling, relative density (Rdi) = species density/total density from all of species, absolute frequent (Fi = total plot in species I/total plot of all species, relative frequent (Rfi) = frequent of species I/total of species frequent, Important Value Index (INP) = relative density + relative frequent. Based on the study result may be concluded that gastropoda class in coastal of Bungatan village Bungatan district Situbondo regency is found 11 mollusca and the highest is nassarius arcularius while lowest is murex tropa.
