Opis:: This study aims to determine what is the influence of the density of mangroves on the rate of coastal sediment transport and abrasion that occurred in the Sikakap Coastal area of Mentawai Island district. The research method used is the quadratic transect method and the sediment trap method. The type of mangrove vegetation that dominates in the Sikakap Coastal area of Mentawai Island district is Avicennia marina. Tree level mangrove density at Station I is 1,450 stands / ha and categorized as good, while the tree level mangrove density at Station II is 900 stands / ha and categorized as heavily damaged mangrove forests. The relationship between mangrove density and transport sediment rate in Sikakap Coastal, Mentawai Island district shows a negative correlation with the value -1, meaning that when mangrove density is high, the transport sediment rate will be low, and vice versa, when mangrove density is low, the transport sediment rate will be high.

Opis:: This research was conducted on November 2018 - January 2019. The method used was the survey method by making direct observations on the stations that have been determined. The results of the research include two types of mangroves found, they are Rhizophora stylosa and Aviciena marina. The highest mangrove density was found at station 1, as many as 2302 ind / ha which dominated by R. stylosa. Gastropods found were Casidulla aurisfelis, Cerithidea sp., C. cingulate, C. alata, C. obtusa, Polinices sp., Puperita sp., Tarebia sp., Telescopium telescopium, and Turricula flammea. The Diversity Index obtained is 0.998 - 2.547, indicating moderate diversity. The uniformity index obtained is 0.10 - 0.27, indicating that there was a dominant community. While the relation between mangrove vegetation density and gastropods was 0.95, this shows that there is a very strong relation between the density of mangroves and gastropods.

Opis:: This research was conducted in Mempawah Mangrove Park, West Kalimantan on July – August 2018. The research aims to map the benthic macrofauna community structure and its relationship with the structure of mangrove vegetation. The research method was a survey and use purposive sampling data method in observation stations based on different stages of mangrove vegetation. The observation stations consists of Avicennia marina and Rhizophora stylosa as the species of mangroves. Station 1 consists of mangroves in seedling size, station 2 consists of mangroves in pole size, and station 3 consists of mangrove trees. The benthic macrofauna consist of 8 species from 3 different classes, merostomata, malacostraca, and gastropods. The highest abundance value (155 ind/m2), diversity index (1,875) and similarity index (0,668) is in station 2. The relationship between benthic macrofauna abundance and mangrove density has -0,356 as the correlation coefficient which indicates that an increase of benthic macrofauna abundance is in line with the decrease of mangrove density. High density value in research shows that the mangrove is in seedling size, and vice versa a low density value indicates the mangrove trees. The coefficient of determination (0,1272) indicating that the abundance of benthic macrofauna is affected by the mangrove density as 12,72% and 87,28% affected by other factors.
