Abstract

Batu Belubang Beach is located in the area of Batu Belubang Village, Pangkalan Baru District, Central Bangka Regency. This region has good marine resource potential, but over time with the increasingly sophisticated technology the potential for marine resources is not only used by fishermen to find fish but also used by the community for floatingmining activities. This can affect the existence of marine ecosystems, especially macrozoobenthos, which are organisms that are very vulnerable to environmental changes. This study aims to analyze the diversity index, uniformity and dominance of macrozoobenthos in the coastal region of the middle bangka belubang rock. Data retrieval was carried out in March 2018 on Batu Belubang beach, the research method used was purposive sampling by taking 3 stations for each station divided into 3 substations 3 times. Data analysis using the correlation analysis method, the parameters taken are the physical chemical parameters of the water. The results of data analysis obtained at the diversity index value at station 1 were 1.33 with the moderate category, the diversity index value at station 2 and station 3 were 0.97 and 0.89 categorized as low. The uniformity index value obtained at station 1 and station 3 is equal to 0.04 and 0.30 with a low category, at station 2 the value of 0.32 is categorized as moderate and the dominance index obtained at stations 1,2 and 3 is 0.30 , 0.29 and 0.30 in the low category. The results of the correlation analysis obtained from the physical chemical parameters on the correlation results of TSS, depth and mud with very influential categories with a correlation value of> 0.75-0.99. The results of the correlation on the value of temperature, pH, current velocity and DO are categorized as strong correlations with values> 0.5-0.75 and the correlation value of the sand is categorized sufficiently with a value of> 0.25-0.5.
