Each month (MarcheAugust) 21 core samples were taken at each of six sampling stations. Macrobenthic fauna were identified at the lowest taxonomical level possible and counted. Biomass was measured as ash-free dry mass (afdm). The average biomass over all stations and months was 3.62 g afdm m À2 , the highest biomass (47.45 g afdm m À2) found at a station in one month was due to abundant occurrence of the bivalve Anadara granosa. Low biomass of macrobenthic fauna at Sembilang peninsula cannot easily be explained but is in line with low biomasses found elsewhere in the tropics. For that reason we analyzed a data set of 268 soft-bottom intertidal biomasses collected worldwide to look for a relationship with latitude. It was shown that average biomass of intertidal macrobenthic fauna in the tropics was significantly (p < 0.05) lower than that at non-tropical sites. A significant second-order relationship between biomass of macrobenthic fauna and latitude was established.

Three replicated transect lines were located at each of six sampling stations. One transect line consisted of randomly 7 cores sampling monthly in 2004, 10 cores sampling monthly in 2005, 2006 and 2016. Macrozoobenthic was identified at the lowest taxonomical level, and counted. Biomass was measured as ash free dry weight. The data compiled by applying statistical analyzing. Stations variables showed significant diference (p<0.05). The highest biomass of macrozoobenthic found at Sungai Dinding estuarine. Macrozoobenthic species which had highest biomass was Tellina remies.
