Abstract

This study analyzed the biophysics of mangrove vegetation environment and the distribution pattern of Teredo navalis L in four mangrove species. Survey method was used and data were obtained by determining, each research station using the path and plot lines, the size of each station with a length of 100 m x width of 50 m, each station placed 5 quadrants measuring 10 m x 20 m, as well as cutting four mangrove species as sample of the Teredo navalis L distribution with a length of 70 cm, which is 10 pieces for each of the mangrove.The results of environmental biophysical measurements show six vegetation species, including: Rizophora, Avicennia, Sonneratia and Bruguiera sp. The coastline's length of stations I and II is 100 meters; these are the Kimalaha and Sangaji rivers. The land is textured with sandy clay, rocky, muddy and black peat soil, and its salinity is in the range of 31 -32 ‰. The water temperature is between 320c - 340c, while the pH value is between is 7.5 - 7.7. The highest T. navalis L distribution index was Rhizopora, and Avicennia sp = 1.2, and the lowest were in Sonneratia and Bruguiera sp = 1.0. At station II, the highest index values for Rhizopora and Avicennia sp were 1.5 and 1.3, while the lowest were Sonneratia sp and Bruguiera sp of 1.0 respectively. Therefore, the distribution pattern of T. navalis L is categorized as clustered and random.
