Abstract

The research was conducted in December 2016-January 2017 in the mangrove ecosystem of Sungaitohor Village, Riau Province. The objective of this research was to analyze the biomass potential of mangrove ecosystem, to know the difference betwen above ground biomass potential (Above Ground Biomass, AGB) and underground biomass (Below Ground Biomass, BGB). Of the ANOVA test results on the levene test count has a value of 5.822 with a probability value of 0.009 (<0.05) then the three variants of the population are identical so that the biomass content of Station 1. Station 2 and Station 3 is not significantly different, the results showed that in the t-independent test results showed no significant differences in the potential value of AGB and BGB. Based on the ANOVA test the finding shawed no significant difference to total biomass at each station in Sungaitohor Village, Meranti Islands District.Keyword : Mangrove, Biomass, Sungaitohor, Meranti

Abstract

This study has been done in Bantan Beach of Bengkalis Regency in Riauin December 2014. This research aims to understand the analyze oil contentdistribution, observing the environmental conditions. The research used surveymethod. The samples were taken from three stations, The water qualityparameters measured were covering temperature, transparency, pH, salinity, andcurrent speed. The result showed the highest oil concentration highest tide was atthe station II,i.e: 0.189 ppm and lowest at stationIII,i.e:0.130 ppm. The highest oilcontent at low tide was at station III,i.e: 0.111ppm and the lowest was at station I,i.e 0.058 ppm. The water quality parameter at the highest tide was temperature31oC–32 oC; transparancy 46-48 cm; pH: 8; salinity: 30.3-31 ppt, currentspeed:0.17-0.24 and lowest tide were temperature of 30.3oC–31 oC; transparancy43-45 cm; pH: 8; salinity: 29.67-30 ppt, current speed:0.16-0.22 m/sec. Theresults obtained showed that the average oil content the tide was higher than theaverage oil content at low tide. The concentration of oil content in Bantan Beachshowed in the range support the aquatic organisms life.Keywords : The oil content, highest tide and lowest tide, Bantan Beach
