Abstract

ABSTRACTThis research was conducted in March 2019 at MedangKampai Waters of Dumai City. This study aims to determine the relationship between particle size and sediment organic matter with abundance of macrozoobenthos in MedangKampai waters. The method used is survey. Determination of stations using purposive sampling method. Sampling was carried out in the field and then taken to the Marine Chemistry Laboratory for analysis of sediment and organic material fractions. The identification of macrozoobenthos was carried out at the Marine Biology Laboratory. The results of the study of sediment fractions showed different types of sediments, namely sandy mud, gravel sand, and mud. Particle size and density of silt sediments (4.90 - 7.30 Ø). The content of organic ingredients is 3.37% - 19.40%. And the abundance of macrozoobenthos ranges from 1.11 ind / m2 - 3.56 ind / m2 with 16 numbers of species found from the dominating class of gastropods. The relationship of sediment particle size (Mz) to the abundance of macrozoobenthos has a value (r) = 0.0721 a very weak relationship (H0.1 is accepted). The relationship between the total organic matter content of sediments and the abundance of macrozoobenthos has a value (r) = 0.1044 which means it has a very weak relationship (H1.1 is accepted). Keywords: Particle Size, Organic Material, Macrozoobenthos,

Abstract

The research was carried out on the breakwater rocks in Water Conservation AreaPariaman West Sumatra Province in May 2013. The goal in conducting this study is tofind out how to survive gastropods in breakwater and sandy beach ecosystems areconstantly subjected to pressure waves. The method used was a survey method thatdirectly observe the behavior and movement of gastropods.There are 5 types of gastropods which have distinctive way of life to survive inthe face of pressure waves. Gastropods movement in the face of pressure waves in thesubmerged breakwater when high tide and exposed to the atmosphere when the low tidesas well as having an active movement, slow and settled. Life pattern gastropods in thesandy habitat gastropods will be attached to rock fragments and other fossil biota. Therewas slow movement that occurs when the wave came. Human impact on the gastropodswill always avoided by attaching themselves to the substrate tightly, closing their shellimmediately and move quickly. Gastropods movement in rock breakwater depends on thecause as something approaching movement (humans and other organisms), exposure tofree air (drought) and the most important is the availability of food.Keywords: Gastropods, survive, breakwaters, pressure waves, West Sumatera

Abstract

The research was conducted in January 2015, in the coastal waters of Bela River Village, Indragiri Hilir Regency, Riau Province. The research aimed to determine the correlation between abundance of windowpane oyster (Placuna sp) and characteristics of sediment in the coastal water of Bela River Village. The research used survey method by performing sampling at 3 stations and each station consisted of 4 sampling points. The stations were chosen from 3 different areas namely estuary, settlement area and mangrove environment.The result showed that abundance of windowpane oyster (Placuna sp) in the coastal water of Bela River Village in January was relatively small. The highest abundance on station 3 at the sampling point 2 was 6000 ind/ha. The lowest abundance on station 1 at the sampling point 3 was 1000 ind/ha. Sediment type of Bela River Village Coast was sandy mud. The correlation between abundance of windowpane oyster and sand fraction was negatively correlated with the value of the correlation coefficient r = 0.573. The correlation between abundance of windowpane oyster and mud fraction was positively correlated with the value of the correlation coefficient r = 0.568, and the correlation between abundance of windowpane oyster and organic materials was also positively correlated with the value of the correlation coefficient r = 0.864.Keywords: abundance, sediment, Sungai Bela, windowpane oyster

Abstract

 ABSTRACT                Microalgae are very potential to be developed as biofuel feedstocks when compared to food crops because they have several advantages such as rapid growth, high productivity, enabling the use of freshwater and seawater, and production costs are not too high. Spirulinaplatensis has a high nutrient content so it is used as a health food ingredient. Once the importance of the role of nutritional value of S. platensis for humans and some marine organisms, then the right culture medium to get the maximum nutritional content needs to be studied more deeply. This study aims to determine the effect of different doses of nutrition on the density of biomass cultivation of S. platensis microalgae with indoor and semi outdoor system. This research has been conducted from April to May 2018. The method by used the experimental method. The data obtained were analyzed statistically using simple linear regression equation. The results showed that the influence in the dose of nutris media guillard, S.platensis increased with the dose of nutrients as much as 0.60 ml either indoor or semi outdoor system. The relationship experienced between biomass with different doses of nutrients is a positive medium with both indoor and semi-outdoor systems, this can be seen from the results of simple linear regression test, namely r = 0.3443 for indoor system and r = 0.4492 for semi-outdoor system. As for the amount of biomass density S. platensis in the semi-outdoor system the amount of biomass density is higher than the indoor system.Key words: Microalga, Spirulina platensis, Sediment, Media Guillard

Abstract

AstractOne of the biota that lives in mangrove ecosystems is the gastropod telescopium telescopium. Telescopium telescopium has more active behavior at spring tide (high tide and low tide) than low tide (low tide and high low tide). The weight of the gonad will reach a maximum of a moment when the mangrove snail will spawn, then the weight of the gonad will decrease rapidly as long as the spawning is in progress until complete. This research was carried out in June-July 2018, sampling in the mangrove ecosystem of Ketapang Beach waters, Sungai Cingam Village, Rupat District, Bengkalis Regency, Riau Province. The samples were analyzed at the Marine Biology Laboratory of the Faculty of Fisheries and Marine Sciences, Riau University. This study aims to determine the population structure of gonad maturity index and habitat conditions of T. telescopium gastropods in Ketapang Beach waters, Sungai Cingam Village, Rupat District. The method used in this research is survey method. Measurement of water quality parameters is carried out in situ, namely temperature, and determination of sampling locations by purposive sampling, salinity and pH, type of substrate in sandy mud dominance. Water quality parameters are still supportive for the life of mangrove snails. Average density of Tcopcopium T in the mangrove forest of Sungai Cingam Village is low. There were no differences in density between the research stations but there were differences in density between the study zones. The average distribution pattern of T. telescopium is clustered. The size of T. telescopium found ranged from 38-87 mm. The main habitat of T. telescopium is in zone 2 (lowere zone).Keywords: Population structure, Telescopium telescopium, Rupat Island.

Abstract

The aim of this research is to know the condition of coral reefs including the live coral cover, the diversity index, the uniformity index, and the dominance index of the waters of Banyan Tree Bintan. This research had been conducted in the waters around Banyan Tree Bintan from September until November 2016. There are three stations with two depth; Angsana House Reef, Rawa Island and Manjin Island. The data of coral reefs were collected by using Underwater Photograph Transect (UPT) method. The result which was analyzed by using CPCe application revealed that the condition of the coral reefs was ranged around 21,88 % to 32,87% which can be classified as poor to moderate category sequentialy. The low number of coral covers was caused by rising sea temperature and coral bleaching. The highest coral cover was located in the Angsana House Reef at a depth of 5 meters in otherwise the lowest one was located in the Rawa island at 2 meters depth. The quality of water such as temperature, salinity, pH, current velocity and the visibility of the research location was good for coral reefs recovery and growth. The diversity index moderate, the uniformity index was low, and the dominance index was ranged from low to moderate level.Keywords: Terumbu Karang, Banyan Tree Bintan, Underwater photograph Transect (UPT), Coral Bleaching.
