Abstract

ABSTRACT                This study is about the use of local government assistance in increasing the income of members of fishermen groups carried out in August 2018 in the nanggari manggopoh palak gadang ulakan tapakis district padang pariaman district. This study aims to find out how members of the fishing group utilize local government assistance in increasing the income of members of the fishing group, hopefully. The method used in this study is a survey method that is analyzed using the simple T-test method and the number of respondents in this study, namely 19 respondents who were used using SPSS 16.               From the results of this study the income of fishermen's catch increased by 75% after obtaining assistance, while the net income of fishermen increased by IDR. 1,500,000 per month. After the pairet simples test, the value of T count is -23,117, while the value of sig (2tailed) (0,000) <(0,05) can be concluded that rejecting H0 and accepting Hi means that there are differences before and after receiving assistance. Keywords:utilization of assistance, regional government

Abstract

ABSTRACTThe research was carried out for 40 days from 18 April to 28 May2019, in the fish hatchery and BreedingLaboratoryDepartment of Aquaculture, Faculty of Fisheries and Marine. University of Riau. The purpose of this researchwas to determine the effect of initial feeding and different feed combinations on the growth and survival of silver barb larvae (Barbonymusgonionotus). The larvae was reased for 40 days, in 16 -Lplastic jar, with 2Larvae/L.The larvae were stockedat 20 larvae/jar. The method used in this research was the experimental method. The design used was a Completely Randomized Design (CRD) one factor with six treatments and three replications.

AbstractThe aim of this research was to determine the effect of stocking density and kind offeed on growth and survival rate of Java barblarvaereared with a water recirculation system. This research was conducted from November-December 2018 at the Fish Hatchery and Breeding Laboratory, Fisheries and Marine Science Faculty Riau University. The Method used was a Factorial Completely RandomizedDesign with two factors.The first was stocking density with three levels, namely 5 larvae/L (T5), 10 larvae/L (T10) and 20 larvae/L (T20). While the second factor waskind of feed with two levels namelyArtemia nauplii (Pa) and Tubifex warm (Pt).The larvae were reared in 10 L-glass aquariumwith a water recirculating system for 40 days. The result showed that stocking density and kind of feedgave asignificant effect in absolute weight, absolute length, average growth rateand survival rateof java barb larvae. The larvae stocked at density of5 larvae/L and fed onArtemia naupliwere significanthy(P<0,05) the highest inabsolute weight (1,11 gr), absolute length (4,35 cm), spesific growth rate (12,49 %/day)and survival rate (99,33 %). The water quality parameters during research were rangedtemperature25,3-27,8°C, pH 5,1-6,5 and dissolved oxygen 4,1-5,2 mg/l. Keywords : Stocking denstity, Kind of feed,Java barb larvae,Growth and Survival rate

Abstract

ABSTRACT               This research was conducted in April 2019 which aims to determine the level of fishermen's satisfaction with sea food supply services at Bungus Ocean Fisheries Port (PPS), West Sumatra Province using the survey method. Determination of the value of satisfaction level is determined using the analysis of the Customer Satisfaction Index (CSI) and analysis of Importance Performance Analysis (IPA). The results showed that the value of the Customer Satisfaction Index (CSI) of each item was very high at 0.84 for clean water, 0.89 for the value of the Customer Satisfaction Index (CSI) of diesel and the value of the Customer Satisfaction Index (CSI) of 0, 87. This number is in the range of 0.81-1.00 which is categorized as very satisfactory. And the results of the IPA analysis show that in each item scattered the attributes of four airports except that clean water is not found in quadrant I.Keywords: West Sumatra Province, level of satisfaction, PPS Bungus

Abstract

ABSTRACT             Phytoplankton is a primary producer organism in aquatic ecosystem and it supplies oxygen to the waters through photosynthesis process. A research aim to determine types and abundance of phytoplankton in the Koto Tibun Reservoir has been carried out on February-March 2018. Sampling taken at three stations, namely Station 1 (riverine zone), Station 2 (transition zone) and Station 3 (lacustrin zone), once/week. Parameters measured were temperature, brightness, depth, pH, DO, CO2, nitrate (NO3) and phosphate (PO4). The types of phytoplankton found in the Koto Tibun Reservoir were 27 species that consist of 5 classes, namely Chlorophyceae (11 species), Baccillarophyceae (8 species), Zygnematophyceae (3 species), Cyanophyceae (4 species) and Euglenophyceae (1 species). The abundance of phytoplankton in Koto Tibun Reservoir ranges from 2,544-3,708 cells/ L. The water quality parameters were as follows:transparency 75.33-78.66 cm, temperatures 25.3-25.6 0C, pH 5, DO 4.78-5.62 mg / L, CO218.64-19.44 mg / L, phosphate 0.093-0.113 mg / L, nitrate 0.186-0.193 mg / L. Based on the abundance of phytoplankton, Koto Tibun Reservoir can be categorized as mesotrophic.Keyword: Phytoplankton, Water Quality Parameters, Koto Tibun Dam,Mesotrophic

Abstract

ABSTRACT Peat Swamp Ecosystem is one of the ecosystems in the wetlands, which is experiencing a shift in the function of oil palm plantations and Industrial Plantation Forests (HTI). This study aims to determine the types of aquatic plants that live in the Peat Swamp Ecosystem Pelalawan Village, Pelalawan Regency, Riau Province. The method used is the method of observation, with descriptive analysis. Sampling is carried out every day for one week until no new species are found. Samples of aquatic plants were identified by Steenis (1981). The results found that there were 4 classes, 10 families and 10 species of aquatic plants that live in the peat swamp ecosystem. Water growth consists of 2 patterns of life, namely floating type, and emergent type. There are aquatic plant species in the peat swamp ecosystem are Eicchorniacrassipes, Ipomoea aquatica, Salvinianatans, Pistiastratiotes, Lycopodiumclavatum, Echinodoruspalaefolius, Paspalumcommersoni, Cyperusrotundus, Nymphaestellata, andLimnocharisflavaKeyword: Peat Swamp Ecosystem, identification, aquatic plants

Abstract

Abstract The water in the pond at PT Bumi Siak Pusako-Pertamina Upstream Eor Plant Gathering Station is polluted by oil. The presence of oil in pond water triggers gene mutations in bacteria so that the bacteria can produce biosurfactants to degrade oil. The aim of this study was to obtain a biosurfactant-producing bacterial isolate and was carried out in January - February 2019. Bacterial isolation was started by taking 5 ml of pool water samples and mixed with 40 ml of Bacterial Fertilizing media namely Brain Heart Infusion (BHI) and then incubated for 1 x 24 hours . Then the bacteria are grown using Mac conkey media. Pure bacteria are biochemically tested and emulsified. Morphological and biochemical characteristics show that 2 species of bacteria, namely Provindensia sp and Citrobacter sp. Emulsification index results show that all bacteria obtained have the potential to produce biosurfactants.Keywords: Providensia sp, Citrobacter sp

Abstract

ABSTRACTRasau and Selempaya riveris one of the Pelalawan village. However, the information about these kinds of fish in the area is still limited. To understand the types of fish present in the rasau and selempaya river, a study has been conducted in March  2019. Catching is carried every day for two weeks until there is no longer found a new species of fish. Fish catching was done by using line fishing’s, “langgi” and “togun”. Fish sampled were then identified based on Kottelat et al. (1993) and Saanin (1968). Results shown that the caught fish consistsof  3 orders, 11 families, 13 genera and  21 species. The condition of the water quality at rasau and selempaya river shows that temperature of  28oC-31oC, brightness of 30-76.5 cm, depth  1,6-4 m, flow velocity 0.010-0.017 m / sec, pH of 5-5.5, dissolved oxygenof 3,7-4,4 mg/L and carbondioxide 16-17 mg/L. Keywords: Identification, Rasau River, Selempaya River
