Abstract

AbstractThis research was conducted in January-February 2019. To determine the types of sediment constituents material and the environmental conditions of the Selat Padang waters based on the texture of surface sediment. The sediment was taken using grab sampler from three station, in which each station consists of three sampling point. The results showed that sediment types were in the waters of the Selat Padang indomination by sandy mud.Sediment parameters in the Selat Padang have an average diameter (Mz) of 5.2-5.33 Ø with the classification of medium silt, sortingthat is2.16-2.93 Ø with the classification is the disaggregated very bad, skewness (-0.12)-(- 0.48) Ø with classification very rough, kurtosis is 4.80 - 25 Ø with the classification very sharp once classified into platikurtik .The sediment compositions found were lithogeneous and biogeneous dominated bylithogenous, indicate the sediment comes from coastal erosion carried by ocean currents and then deposited in the bottom of the watersThe highest average value of organic materials contained in the station 1 (12.76%) located in Sei Selari port which is included in the classification of the medium organic matter indicate little supply of organic material from the sea to the coast. Keywords: Selat Padang, Sediment, Sediment Composition, Organic Material

Abstract

This research was conducted from January to March 2016 in Sironjong Gadang Island. The island is located in the sub-district of Koto XI, in the region of South Coast Regency of West Sumatera Province. The aimed of this research was to determine the growth and the survival rate of Acropora intermedia plantations. Experimental methods were applied by measuring the growth rate and counting the survival rate of the coral transplants. Besides, the surrounding parameters of water quality were also measured in the field. The result showed that the lateral growth of the transplant was faster than the vertical one; the values were 0.748 cm and 1.512 cm consecutively. In addition, the survival rate reaches 90 %, however, bleaching coral and dead coral with algae was also found in the first 20 days of observation.Keyword: Acropora intermedia, Growth Rate, Sironjong Gadang Island

Abstract

This research was conducted in January 2015 with the aim to determine the characteristics of the sediment vertically in Bengkalis Strait. This research used survey method which divided into 7 stations. Sediment samples were taken by using gravity cores. Analysis of the sediment was carried by the size of the analytical method and the drying method.The results showed that sediments in the location was dominated by sand fraction, then mud and gravel fractions. The result of Sediment grain size analysis showed that Bengkalis Strait have characteristics of coarse sand, medium sand, fine sand, very fine sand, silt and medium coarse silt with sorting coefficient consists of well sorted, moderately well sorted, moderately sorted, sorted pooly and very pooly sorted. The distribution of sediment was very fine skewed, fine skewed, near symmetrical, coarse and very coarse skewed. Common sediment characteristics between the station was also seen in the cluster analysis. The results of cluster analysis showed that the sediment grouped into five groups showing clearly different in the characteristics of the sediment between the stations in this area.Keywords: Vertical Distribution, Sediment, Bengkalis Strait, characteristics

Abstract

Tiger shrimp is one of the most popular fishery products in the world. H. scabra has been shown to be a potential antibacterial agent. Potential antibacterial extract from H. scabra can be derived from the presence of antibacterial agents i.e steroids, saponins and triterpenoids. Bacteria V. harveyi is one of pathogenic bacteria which according to some research can cause disease in shrimp cultivation. Diseases caused by vibrio bacteria are usually called vibriosis. The purpose of this research is to know the effect of antibacterial activity of sea cucumber extract (H. scabra) on the growth of V.harveyi bacteria on tiger shrimp (P. monodon), to know the character and structure of bacteria which is inhibited by sea cucumber extract (H. scabra). This research was conducted in August 2016 in Marine Microbiology Laboratorium of Riau University. Based on the results of research that sea cucumber extract has the ability to inhibit the activity of V. harveyi bacteria. The mean value of the inlet zone is 4.06 - 6.26 mm.Keywords: Sea cucumber, Antibacterial, V. harveyi

Abstract

The research was conducted in June 2015 in the estuary of Kampar River of Teluk Meranti Pelalawan Riau Province. The purpose of this study was to determine the content of organic materials in sediments and abundance of macrozoobenthos. The method used in this study was a survey method. The stations was determined based on a purposive sampling which consisted of 3 stations, and each station was divided into 5 plots. The results showed that the sediment in the estuary of Teluk Meranti was dominated by sandy mud with organic materials content ranging from 1.15 to 2.08%. There were two classes of Macrozoobenthos found, Bivalves and Polychaetes with abundance 46-70 ind/m2. Its diversity index (H') was low, but high in term of dominance index (C). The uniformity index value (E) showed that species spread unevenly. The relationship between organic content and abundance of macrozoobenthos indicates an intermediate correlation with Y = 90,326-21,95x (r = 0.41, R2 = 0.1696). It seems that abundance of Macrozoobenthos in this area was more influenced by other environmental factors.Key words : Organics materials, abundance, macrozoobenthos, Teluk Meranti

Abstract

AbstractThis study was conducted in the intertidal zone of Surantih Beach, South Coast Regency, in the West Sumatra province. It aims to learn the distribution pattern and abundance of bivalves (D. cunneatus and D. deloides). Sampling locations were chosen purposively with different characteristic. The field samples were collected with shovel along the transect line then filtered with 1 sq. mm in size for further analysis in the lab. The result showed that these two species are found, namely, D. cunneattus and D. deltiodes. The abundance of these bivalves in the intertidal of Surantih Beach ranges from 2.83 -3.63 individual per sq. meter where the highest one was found in the third station. These species have aggregated distribution structures in the area under study.Keywords: Bivalvia, Intertidal Zone, D. Cunneatus, D. Deltoides, Abundance, Distribution Patterns, Surantih Beach.

This research was conducted in December 2015 in the Belimbing Bay coastal area of the PesisirSelatan Regency, West Sumatra Province. The purpose of study was to determine the distribution andabundance of bivalves in the intertidal zone. Bivalves samples were taken by using Quadrant TransectSampling Method, in which at each station had one line transect, divided into three plots with a size of3x3 m2, respectively. The study found the abundance of the bivalves at station I (middle zone) washigher (0.15 ind/m2) than in the lower zone (0.07 ind/m2). In station II the lower zone was 0.07 ind/m2lower while the middle zone was 0.16 ind/m2. In station III the highest abundance was in the middlezone (0.15 ind/m2) and the lowest abundance was in the lower zone (0.08 ind/m2). The highest organicmatter content in the station I was 6.97% and the lowest was in the upper zone (4.85%). The lowestorganic matter at station II was lower zone (5.48%), followed by the upper zone (5.74%), and thehighest is in the middle zone (5.96%).
