Abstract

This research aim to determine the optimal dose of additional probiotic in feed toward the growth performance and survival rate of tambaqui (Colossoma macropomum) by using biofloc system. This research was conducted on March 30-May 9, 2018 at Technical Service Unit (UPT) of Hatchery, Marine and Fisheries Faculty, University of Riau. This research was using experimental method by completely random design (RAL) one factor with three replications. The treatments were: A: 0 g/kg of feed (control), B: 0,5 g/kg of feed, C: 1 g/kg of feed, and D: 2 g/kg of feed. The probiotic (Bacillus sp) The results showed that a different doses of additional probiotic affecting the growth performance and the survival rate of tambaqui using biofloc system. In addition, it also affected the absolute weight growth, absolute length growth, feed efficiency and feed conversion ratio.The optimal dose was at 2 g/kg of feed as it showed significantly different results compared to control and was not differ significantly at higher doses. So that while being applied in terms of economy, 2 g/kg was the most efficient dose, by giving the absolute weight growth was 37,62 g, absolute length was 6,91 cm, specific growth rate was 7,00%, feed efficiency was 104,16%, feed conversion ratio was 0,96 and survival rate was 100%.

Abstract

This research was conducted on Desember 2016 - April 2017. The purpose of this study is to determine the amount of fermented flour from Moringa leaf in the feed which affect the growth, feed efficiency, feed digestibility and protein retention in gouramy (Osphronemus gouramy). This study uses a completely randomized design (CRD) with one factor, 5 treatments and 3 replications. The treatment with substitution of fermented moringa leaf flour, Controls (0: 100%), P1 (10: 90%), P2 (15: 85%), P3 (20: 80%), P4 (25: 75%). The feed contain protein of 30%. The results showed that the best result is the highest treatment from P2 (15: 85%) with a specific growth rate of 1.58% / day, feed efficiency rate of 18.44%, 73.82% of feed digestibility and protein retention 15.82%.

Abstract

Heterotrophic bacteria are bacteria that are able to utilize organic matte as a source of carbon and energy. Heterotrophic bacteria live and have an important role in aquatic ecosystems. Pathogenic bacteria V. alginolyticus, A. hydrophila and Pseudomonas sp are pathogenic bacteria against fish. This study aims to isolate, identify, test the ability of the bacteria as antibacterial against pathogenic bacteria and determine the characteristics of heterotrophic bacteria using 16S rRNA sequences.this research was conducted from January to March 2019 whivh took place in the Mnagrove Area in the Marine Station Dumai, Riau Province. Based on the results of the research that has been done, it was obtained 8 pure bacterial isolates used to observe the morphology of bacterial colonies, biochemical tests and antagonism tests against pathogenic bacteria. Based on the results of the antagonism test, it was obtained the best 2 isolates for DNA analysis. The results of DNA analysis using PCR 16S rRNA method and BLAST analysis were Bacillus amyloliquefaciens strain SH20, and Bacillus cereus strain NY180

Abstract

Research was conducted from October to December 2017, at the labory Examination of Fish Disease, Fisheries and Marine Faculty of Universitas Riau. The Purpose of this study was to determine the sensitivity of harumanis mango seed (Mangifera indica L) as antimicrobial to A. hydrophila, the range of Minimal Inhibitory Concentration (MIC) and the lethal dose (LD50) harumanis manggo seed (M. indica L) solution against to catfish (Pangasius pangasius) (7-9 cm) by immersion. The research method used doses; D1: 100%; D2: 90%; D3: 80%; D4: 70%; D5: 60%; D6: 50%; D7: 40%; D8: 30%; D9: 20% D10: 10%, and K : Control (Oxytetracyclin).The results showed that mango seed solution was sensitive to A. hydrophila bacteri and was able to inhibit A. hydrophila up to 0.09% dose with inhibit zone of 7.31 mm. Minimum Inhibitory Concetrantion (MIC) is 0.1% (1000 ppm) number of colonies 270.66 CFU/ mL.The dose of LD50 is 2115,85 ppm

Abstract

SSC (Sediment Suspended Concentration) is the concentration of suspended sediment. This research was conducted in June 2018 in the Muara Sungai Padang area, Bandar Khalifah District, Serdang Bedagai Regency, North Sumatra Province. This research aims to describe the distribution of vertical and horizontal SSC suspended sediments and the factors that influence them in Padang river estuary  area, Bandar Khalifah District, North Sumatra Province. The method used in this research is the survey method and determining the location of sampling by purposive sampling. Measurement of water quality parameters is carried out in situ, namely temperature, salinity, pH, depth, current speed, and brightness. The results of the study of the distribution of suspended sediments in the waters of the Padang river can be concluded that the pattern of the distribution of suspended sediments when the tide moves towards the upper reaches of the river while at low tide moves towards the sea, namely the waters of the Malacca Strait which is influenced by currents. the largest suspended sediment concentration at tide to low tide is at the sampling point 1 which is 179 mg / l and recedes to pairs at sampling point 1 which is 121 mg / l.

Abstract

Land can be said to be fertile seen from Biological factors. One of the Biological factors determining soil fertility is the population of bacteria in the soil. The purpose of this study was to calculate the population and describe the bacterial morphology of the Kampar Riau Sumatera Watershed. The method used in the this study is the observation and Coloni Counter method. Peat soil sampling was carried out at 8 peat soil points along the Kampar Riau Sumatera Watershed. Isolates were carried out using agar nutrient media and were fertilized for 24-48 hours at 370C. Macroscopic and microscopic observations were carried out to determine bacterial morphology. This research result obtained 16 isolates from 8 sample locations. The highest number of bacterial populations in the village of Kuala Terusan was 51,55 x 104 CFU/Unit and the lowest was found in Meranti Village with 12,93 x 104. Identified bacterial morfoligical characteristics are irregular, round, round with embossed edges and threaded threads. Cell shape 2 which is stem and round the catalase test are all positive

Abstract

This research was conducted in May - August 2018 in the waters of Sasak Beach Pasaman Barat, West Sumatra Province. The purpose of this research was to determine the relative sedimentation velocity, the type of benthic foraminifera, and the distribution pattern of benthic foraminifera in the waters of Sasak Beach Pasaman Barat, West Sumatra. The method used in this research is purposive sampling method which is divided into 3 stations. The highest relative sedimentation velocity is found at Station I with a value of 28.0%, the relative sedimentation velocity is highest at station II with a value of 35.0%, and at station III 20.0%. The most commonly found foraminifera species are Ammonia beccarii, Quinqueloculina disparilis and Quinqueloculina laviegata. Benthic foraminifera from 3 observation stations can be divided into 6 groups. Group I was characterized by Ammonia beccarii (Line Form B), Ammonia beccarii (Line Form C), Textularia aglutinans and Trochammina inflate. Group II is characterized by Ammonia beccarii (Line Form A, B and C), Nonionoides gratelouupi, Quinqueloculina laviegata, and Spiroloculina laviegata. Group III is characterized by Ammonia beccarii (Line Form A, B and C), Spiroloculina laviegata, and Triloculina oblonga. Group IV is characterized by Ammonia beccarii (Line Form A, B and C), Nonionoides gratelouupi, Quinqueloculina disparilis, and Miliolina subrotunda. Group V is characterized by Ammonia beccarii (Line Form A, B and C), Quinqueloculina laevigata and Spiroloculina laevigata. Group VI is characterized by Ammonia beccarii (Line Form A, B and C), and Sigmoilinita distort. The distribution pattern of benthic foraminifera tends to clumped

Abstract

This research was conducted from May to July 2018 in Tulang Island, Karimun Regency, Riau Islands Province.The purpose of this study is to understand the activities of community ports on Tulang Island and the economic driving factors of the Tulang Island community. The method used in this study is a qualitative method. Activities found from both people's port is the movement of people, goods and services. Economic driving factor in terms of trade slightly hampered in the process of loading and unloading goods, for service delivery factors there is no on the Tulang island, while fisheries and marine factors, in Tulang Island, it is in need of a decent port so that the process of loading catches such as shrimp, fish, and other commodities can be maximized.
