Abstract

This study was conducted from March to April 2016 in the Laboratory of PhysicalOceanography Marine Science Department Faculty of Fisheries and Marine Science University ofRiau. This study aimed to explain a relationship between current velocity and wave propagationspeed, and sediment particle size to the results of sediment transport volume. The method used wasan experimental design with 4 treatments. Current velocity and wave propagation speed wereconsists of 2 level factors (V1 and V2) and sediment particle size were consists of 2 level factors(D1 and D2). Observations used the flume tank and wave generator for 10 minutes. The resultsshow that there was an effect of current velocity, wave propagation, and sediment particle size tosediment transport volume. If the current velocity increase so sediment transport volume alsoincreased. While if sediment particle size increase the sediment transport volume decreased.Observations in the laboratory and calculation of sediment transport that used an Engelund-Hansenformula showed differences. Differences caused by oceanographic factors such as water andsediment density, gravity, water depth, salinity and consistency.Keywords: The Volume of Sediment Transport, Current, Wave, Particle, Velocity.

Abstract

AbstractMangrove is a tree that normally grows in the intertidal zone of marine coastal environments. The study aim to analyze density of mangrove, to analyze the biomass content, carbon content and ability to absorb carbon dioxide gas in mangrove ecosystem, to analyze the effect of mangrove density on biomass, carbon stock and CO2 uptake and to analyze the comparison of biomass, carbon stock and CO2 uptake between stations. This research was held in November 2017 by survey method and used the data of mangrove species, it’s number and diameter of breast height (DBH) on each sub plot. Measurement of mangrove biomass was done allometric equation method. The result of carbon stock and CO2 uptake in mangrove indicates that Station I was higher than Station II and III.  The result of calculation density of mangrove was equal to 2.839,50 ind/ha. The average yield of mangrove carbon stock and CO2 uptake was 670,89  ton/ha and 2.459,35 ton/ha. As for the average yield of soil organic carbon was 1.758,65 tons/ha. The density of mangrove biomass, carbon content and CO2 uptake which has a strong relationship. The content of biomass, mangrove carbon and CO2 uptake were significantly different (p <0.05) among stations. Keywords: Mangrove, Carbon, Sungaitohor Village

Abstract

Sea surface temperature (SST) and chlorophyll-a are important water qualityparameter in the sea, especially the coastal areas. The research was conducted inJanuary - March 2017 in the waters of Belawan, North Sumatera Province with theaim to determine the relationship of sea surface temperature and chlorophyllconcentrations-a.The method used is survey with direct measurements in the watersof Belawan, North Sumatera and using MODIS Aqua satellite image data in March2016 - February 2017. Sea surface temperature MODIS Aqua satellite image datain March 2016 - February 2017 ranged from 29.45 to 31.7oC and chlorophyll-arange of 0.48 to 2.62 mg / l. Field data sea surface temperature ranges from 26-30°Cand chlorophyll-a range of 2.08 to 17.62 mg / l. Interpretation of the data from theMODIS Aqua satellite imagery and field data to explain that the sea surfacetemperature and chlorophyll concentrations-a very weak, r = 0.1791. Data weremapped to show the variability of sea surface temperature and chlorophyll-aconcentrations March 2016 until February 2017.Keywords: Sea Surface Temperature, Chlorophyll-a, Belawan Water

Abstract

The research has conducted in November 2016-April 2017 in Rokan Hilir Regency and was aimed to identify and inventory the data of mangrove forest area in 1994-2017 at Rokan Hilir Regency using Landsat image data analysis . The research was conducted by survey method. The quantitative method was used on the change of mangrove forest area observation. The result of 473 RGB composite on Landsat 5 and 564 RGB composite on Landsat 8 image showed the mangrove areas in 1994, 2004, 2007 and 2017 are 31,550 ha, 28,370 ha, 23,357 ha and 19,724 ha. There was a decrease of 3,180 ha in total of mangrove area in 1994-2004, in 2004-2007 was 5,013 ha and in 2007-2017 was of 3,633 ha which if added in the period of 23 years there was a decrease of 11,826 ha of mangrove area. The accuracy test of interpretation results and ground check results obtained a value of 100% accuracy, while the accuracy test between landsat images and the the results of classification obtained 95.6%.Keywords : Mangrove Forest, Change of Area, Landsat Image, Rokan Hilir

Abstract

This research was conducted in July 2016 at the coastal waters of Pasir Jambak Padang City West Sumatera Province with intention to determine the characteristics of wave and tidal currents. The stasion observation way is determined by using a purposive method. Research location divided into three stations, where each station consists of three sampling points, the distance between stations of approximately 100 m. Performed during 15 days of observation. Every station was placed parallel to the coastline, a distance less than 100 meters from the beach toward the Sea. High wave at high tide ranges from 0.21 - 0.33 m and 0.23 - 0.35 m at low tide. Wave period ranges from 1.54 to 2.23 seconds at high tide and 1.43 to 1.97 seconds at low tide. Wavelength ranges between 3.86 to 7.8 m at high tide and 3.35 to 6.08 m at low tide. Current velocity ranges between 0.37 to 0.64 m/sec at high tide and 0.36 to 0.51 m/sec at low tide. At the high tide the flow towards the southeast and at the low tide towards to the southwest.Key words: Current, Wave, Pasir Jambak, Padang, West Sumatra
