Abstract

This research was conducted in March-May 2014 in central study mangrovemarine station University Riau. This study aims to determine the effect of spacingon percentage seedling survival and growth of Rhizophora apiculata. The methodused in this research were experimental methods. Spacing treatment tested in thisstudy were: (1) Planting with a distance of 25 cm x 25 cm (2) Planting with adistance of 50 cm x 50 cm (3) Planting with a distance of 75 cm x 75 cm and (4)Planting by distance planting 100 cm x 100 cm. The results of the study for 45days was observed that the percentage of survival of the seedlings of Rhizophoraapiculata in various types of treatment spacing of the percentage of live 100%.Seedling height growth of Rhizophora apiculata good are at a spacing of 75 cm x75 cm (treatment C3) with average growth height of 0.080 cm/day. Meanwhile,the best steam diameter growth is best on Rhizophora apiculata are at a spacing of25 cm x 25 cm (treatment A2), with a trunk diameter growth of 0.0030 cm / day.The highest growth the number of leaves on the seedlings reached 4.9 strandscontained in a spacing of 25 cm x 25 cm (treatment A1). The data showed thatthere was effect of spacing on height growth, diameter growth and number ofleaves on Rhizophora apiculata seedlings, while the Anova test obtained therewas no the significant effect of spacing (Sig. > 0.05). It means that the proposedhypothesis (Ho) is accepted and (Ha) was rejected, which indicates that theprovision of spacing did not significantly affect height growth, diameter growthand number of leaves on Rhizophora apiculata seedlings during the observation.Keywords: Marine station, Rhizophora apiculata, The Effect of Spacing.1).

Abstract

This research was conducted in May 2014 in the western part of the RupatStrait Riau Province with its aims to determine the distribution of benthicforaminifera and sedimentation relative velocity. The determination of samplingpoints was done by using purposive sampling method. The sediments were taken byusing Eckman Grab then preserved with Rose Bengal mixed by formalin .The results showed that benthic foraminifera was found in higher amounts inthe north and south of the study site. By contrast, the smaller number was found inthe middle of the strait and the shoreline with the mangrove. These areas werepredominantly influenced by the high flow of current and mangrove area, withrelatively moderate sedimentation velocity. In West Rupat the waters was dividedinto 3 clusters based on the data distribution of benthic species foraminefera namely:group I was found in the northern, central and southern part of the study sites,characterized by dominating species of Reussella hayasakai, Textularia orbica andBolivina humilis and sediment classified as very fine sand; group II was found in thenorthern part of the study site with species that as dominated wereFissuripolymorphina aequicellaris, Rosalina Concina and Bolivina humilis with highorganic matter content in the study sites; group III was found in the southern part ofresearch location with the dominating species were Ammonia beccari, Textulariaarticulata and Textularia neoconica with the bottom sediments belonging to very finesand.Keywords : benthic foraminifera, sediment, Rupat Strait..

Abstract

This research was take place in north Rupat island beach, Bengkalis regency Riau province on January 2016. The purpose of this research is to find out the contents of nitrate and phosphate in the water of seagrass ecosystem in north Rupat island and to find out the contents of nitrate and phosphate in the sediment of seagrass ecosystem in north Rupat island as well as to find out the difference of nitrate and phosphate contents in the water and sediment between station. The parameter that have been observed is the physics and chemist of water parameter. Transect squares device was use to calculated the density. While to determine nitrate and phosphate in the water leads to Saeni and Latifah in Sanggam, 2008 and to determine nitrate and phosphate in sediment leads to Siaka et al., 1998. Base on research result the average content of nitrate in the water is 0.2264-0.2417 mg/L, and in the sediment 0.1347-0,.5319 mg/L. While the average content of phosphate in the water was 0.1991-0.2433 mg/L, and in the sediment 0.2507-0.3872 mg/L. The density of seagrass on each station in north Rupat island beach was about 23.66-154.66 stands/m2. From the result of this research we found from the t test result, the significant differences of content of nitrate and phosphate in water an cediment show that the differences is not significant, show that the condition of north coatsal of Rupat island is water that has midlle level of pressure and polution.Keywords: density of seagrass, Nitrate, Phosphate, Water, Sediment, Seagrass Ecosystems, North Shore Rupat Island, Riau Province

Abstract

Seagrasses are plants adapted to live fully in the marine environment. Seagrass plays an important role in coastal areas due to critical habitat for many kinds of marine animals such as fish, molluscs, crustaceans, echinoderms. The research was conducted inJanuary 2015 inBeruk Island Waters in order to know the different of seagrass distribution and density in northern and southern partsof Beruk Island. The method used was line transect and applyingsix stations, namely stations I, II and III in the southern part of Beruk Island and stations IV, V and VI in the northern area of Beruk Island. The results obtained II seagrass species, i.e. Enhalus acoroides and Halophila ovalis.The pattern of distribution of seagrass at southern of Beruk Island was randomized and E. acoroideswas found as the most dominant species. However,the distribution  in northern of Beruk Island was cluster at station IV and V and randomized at station VI with the dominant species wasH. ovalis. The highest E. acoroides density was found in southern of Beruk Island at station II with the total density of 80 individuals/m2.The highest H. ovalis density in northern partof Beruk Island was at station V with the total density of40 individuals/m2.
