Abstract

This research was conducted in February to March 2017 in Dumai River estuary of Riau Province, with the aim to find out if there is any differences the total organic matter content and the abundance of phytoplankton between stations, and the relationship between total organic matter with the abundance of phytoplankton. The method used is a survey method consisting of 4 stations with 3 replications at each station. Based on the results, the highest average total organic content was found in Station 1 (24,01 mg/L) and lowest was at Station 3 (7,37 mg/L). There is a difference of total organic matter content between stations. There are 8 types of phytoplankton that found on the surface waters of the Dumai River estuary, where the most dominant type is Isthmia sp. The highest abundance of phytoplankton was found at Station 4 (4443,98 ind/L), and the lowest was at Station 2 (1367,41 ind/L). There was no difference in abundance of phytoplankton between stations. The relationship of total organic matter content with phytoplankton abundance shows a moderate negative relationship, which means that the increasing of total organic matter content will decrease the abundance of phytoplankton in the waters of Dumai River estuary.Keywords: Dumai River Estuary, Abudance of Phytoplankton, Total Organic Matter

Abstract

This research was conducted from September-October 2016 at Paya Kundur marine waters, Karimun Regency of Riau Islands Province. Samples were analyzed in the laboratory of Marine Chemistry, Marine Science Department, Faculty of Marine and Fisheries University of Riau. This study aims to determine the vertical profiles of suspended sediment in the marine environment Paya Kundur. This study used survey method, which consists of nine sampling points. Water samples were taken vertically, consists of three levels, namely surface waters, middle (columns), and bottom waters with a distance of ± 6 m. Vertically (surface, middle and bottom) of the distribution of suspended sediment influenced by tidal currents, the location and tin mining activities in bottom waters. The distribution pattern of suspended sediments at ebb tide and flood tide has the highest content at the bottom. The highest content of suspended sediment distribution dominated in the tin mining area to the west of Kundur. Based on quality standart for marine organisme and TSS for fisheries, it can be concluded that waters fertility of Paya Kundur has passed the quality standard and its not suitable for fisheries activities.Keywords: Suspended Sediments, Marine Waters Paya Kundur

Abstract

Nirwana beach is one of tourist destinations in the Sumatera Barat Province. The input of pollutant originated from anthropogenic activities, however, reducing the water quality and as a consequence negatively affects the seagrass ecosystem as well as the associated organisms, including gastropods. To understand the diversity of gastropod in the seagrass ecosystem and the water quality, a research was conducted on September 2016. There were 3 stations and in each stations there were 3 lines. In each line, 5 quadrants (1 x 1 m2) were placed. Gastropods present inside the quadrant were sampled manually. Results shown that there were 16 gastropods species present, they were Cerithium asper, C. litteratum, C. lutosum, Clithon sp., Clypeomorus bifasciata, Columbella sp., Conus sp., Cypraea sp., Morula margariticola, Nassarius sp., Natica sp., Nerita histrio, N. squamulata, Polinices tumidus, Strombus sp. and Turbo sp. The value of diversity index (H’) was 2.193-2.370 and the dominance index (C) was 0.2485-0.3147. The water quality parameters are as follows : temperature was 30-31 0C; depth was 0.24-0.54 m; pH was 8; salinity was 33.3 0/00 and DO was 4.20-6.35 mg/L. Data obtained indicate that the diversity and the water quality in the Nirwana Beach is good and able to support the life of gastropods.Keywords: Diversity, Gastropods, Nirwana Beach, Seagrass EcosystemPENDAHULUANPantai Nirwana terletak di Kecamatan Lubuk

Abstract

ABSTRACT The research was conducted from July to September 2017 in Estuary of Siak River. The purpose of this research is to examine thepopulation of heterotrophic bacteria in Estuary of Siak River, and heterotrophic bacteria antagonism against pathogenic bacteria (Vibrio sp, Aeromonas sp and Pseudomonas sp). And than identified by phenotype and genotype. This research use survey method. The samples analisis were conducted at the Marine Microbiology Laboratory of Marine Science Department of Fisheries and Marine Faculty and DNA analisis conducted at the Genetic Laboratory of Biology Department Mathematic and Natural Sciences. The result of antagonism test from 25 isolate heterotrophic bacterial was found 10 isolates which have ability to inhibit the growth of pathogenic bacteria (Vibrio sp, Aeromonas sp and Pseudomonas sp). From Vibrio sp bacteria the mean of clear zone is 1P11 isolate of 20,3 mm and the smallest is 1P19 isolate of 5 mm. Aeromonas sp bacteria the largest clear zone is 2P20 of 9,3 mm and the smallest is 1P12 isolate of 3,3 mm. Pseudomonas sp bacteria the largest clear zone is 1P12 isolate of 17 mm and the smallest is 1P11 and 2P22 isolate of 8,3 mm. the result of molecular identification using PCR 16S rRNA method and BLAST analisis showed 10 isolates of heterotrophic bacteria having kinship with bacteria of the genus Bacillus that is Bacillus cereus (1P11, 1P12, 1P14, 1P15, 1P19, 2P20, 2P21, 2P23), Bacillus toyonensis (2P22) and Virgibacillus salarius (1P18). Keyword : Heterotrophic Bacteria, Isolation, Antagonism test, Identification

Sampling using transect method squares and samples were analyzed at the Marine Biological Laboratory of the Faculty of Fisheries and Marine Sciences, then presented and discussed descriptively with various references. Based on the research of macrozoobenthos abundance is highest was at station 1 92.00 ind / m², and was lowest abundance at the station 3 is 9.20 ind / m². Found four classes of macrozoobenthos are gastropods, Malacostraca, Maxillopoda, and Ophiuroidae, where gastropods eight species, one species Malacostraca, one species Maxillopoda and one species Ophiuroidae. Species diversity index values ranging between 1.685 - 2.057, the dominance index ranges from 0.30676 - 0.45963, uniformity index ranging between 0.78784 - 0.99344. Batu Asahan waters condition based on water quality parameters measured was able to support the life in particular macrozoobenthos and marine organisms in general.Keywords: Macrozoobenthos, Abundance, Batu Asahan Beach, West Sumatera

Abstract

This research was conducted from January to March 2017 in the Kualu Nenas Village, Tambang district, Kampar Regency, Riau and in Environmental Quality Aquaculture, Faculty of Fisheries and Marine University of Riau. The objective of this research is to know the effect of vermicompost type on change of soil physics properties and peat pond water such as the soil color, crude soil fiber, bulk density, soil porosity, temperature, turbidity dan total suspended solid. The experimental design used a complete randomized design (CRD) with four treatments and three replications by linear model of Sudjana (1991). The treatments applied were without vermicompost (P0), vermicompost from human fecal (P1), vermicompost from cow dung (P2), vermicompost from chicken manure (P3). The result of this study showed that P1 (vermicompost from human fecal) was the best treatment for (crude soil fiber 60.3a %; BD 0.41a g/cm3 and porosity 65a %,). For the turbidity and TSS, The best result in P0 (control). For the soil colour of vermicompost is not effect. the temperature was water that range from 26-31oC the range temperature is still quite good for aquatic organism.Keywords : Lumbricus sp., Peat Land, Physical Parameter, Vermicompost
