Abstract: Sea urchin is one of the marine species with high economic value. It also plays an important role in maintaining the equilibrium of ecosystem in its habitat. There are many ecological differences found in intertidal zone such as sandy area, rocky area, and muddy estuaries. The aim of this research was to determine the relationship between physical-chemical factors and diversity index of Sea urchin at kampung baru coastal, Banda Island Central Maluku. The belt transect method was the sampling method used in this research. The research area was divided into three stations with 225 m-distance between stations. The area of each station was 1000 m2 where three lines transects each with 50 m long were placed perpendicular to the coastline starting from the highest tide to the lowest tide. Each transect was separated by a distance of 50 m. At each transect, five 1m x 1m square plots were placed alternately with the 10 m distance between the plots. The physical and chemical factors were measured at the time of high tide, whereas the observation of Sea Urchin was done at the time of low tide. The results of the research show that the index of diversity is in the low category and the diversity values are in a range of 0.279 to 0.497 with a uniform distribution pattern. The result of the research also shows that there is no correlation between the physical-chemical factors and the diversity of Sea Urchin on Kampung Baru coastal area, Banda Island.
