Abstract:
Falitha 2019. Structure of the Mangrove community based on substrate in Tanjung Limau village, Muara
Badak, Kutai Kartanegara. This research was done in May 2019, when The data was undertaken with the
transek lines and tenement example (transect) plot line with stretched as far as the transek 100 m and make a
plot 10 x 10m plot as many as 10 plots. Chemical physical parameters waters in the form of temperature,
salinitas, pH, DO and substrate also pH of sediment and womb organic matter as well .A fraction and
textures of sample in each station were analyze as sand, with a value fraction ranged in 1st station arround
93,30 % to 97,60 % . the 2nd station in ranged 89,60 % to 96,10 % at 3rd station ranged from 90,30 % to
95,00 %. The pH in substrate were in ranged 6,70-6,90 in 1st station, 2nd station in ranged 6.60 savings
6.75 , and in ranged of 6,50-6.65 in 3rd station .The value of n-Total to station I ranged from 0,04 %-0,05 %,
on station II of 0,04 % and in station III bekisar between 0,04 0,11 % .I value c-organik on station ranges
from 0,19 % 0,58 %, on station ii ranged from 0,29 % 0,48 % and in station iii ranged from 0,29 % 1,79 %
and to value the ratio of c / n at station i ranged from 3,61 % 10,84 %, on station ii 6,87 % 11,45 % and in
station iii ranged from 6,87 % 15,58 %. Type mangrove found 13 types of Bruguiera gymnorhiza , Avicennia
rumphiana , Nypa , Avicennia officinalis ,Rrhizophora apiculata , Rhizophora mucronata , Avicennia alba ,
Bruguiera cylindrica , avicennia marina , sonneratia alba , ceriops zippeliana , sonneratia caseolaris ,
Rhizophora stylosa value and the density on mangrove ecosystem in coastal pangempang the highest the
species Bruguiera gymnorhiza with the highest be at the station 2 , the highest diversity at the station i with
0,0812 value.
Keywords: mangrove community, substrate, transect, the estuary of Muara Badak
