Abstract

In the Kampar River there are activities that affect the water quality in general and affect the abundance gastropoda. To understand the abundance of gastropoda in that river, a study has been conducted in February to March 2017. Parameters meansured were types and abundance of gastropoda, temperature, depth, turbidity, current speed, pH, dissolved oxygen, COD and BOD5 concentration. Sampling were conducted 3 times, once/week, in 5 statiun. Relationship between gastropoda abundance and organic material content was analyzed using a simple linear regression. Result shown that there were 6 gastropoda spesies present, namely Melanoides granifera (20/m2), Melanoides tubercullata (120/m2), Bellamya sp (45/m2), Brothia sp (28/m2), Pila ampullacea (25/m2) and Thiarascabra(4/m2). Organic material content in the sediment was 21.2-73.05%. While the type of sediment fractions that dominate the waters of theKamparRiver is sand and gravel. There was strong relationship between gastropoda abundance and organic material content (96%).Keywords:Makrozoobentos,Melanoides tuberculata, Organic Matter,Sediment Fraction, Kampar River

Abstract

Samsam swamp is located in the peat swamp area and flooded during rainy season. To understand the types and abundance of phytoplankton present in that swamp, a study has been conducted in March 2016. There were four sampling sites, namely S1 is in the upstream (almost no human activity); S2 ( around palm plantation); S3 (around the newly planted palm plantation) and S4 (far from palm plantation). Water sampler were taken once/week for 3 week period. Results shown that there are 21 species of phytoplankton present in the swamp. They were classified into three classes, `namely: Bacillariophyceae (12 species), Chloropyhceae (6 species) and Cyanophyceae (3 species). The average of phytoplankton abundance was around 2,804 – 4,135 cells/L. While the water quality parameters were as follows: temperature: 30 - 320C, transparency: 30 - 40 cm, depth: 83 - 114 cm, pH: 4 - 5, CO2: 8.66 - 9.32 mg/L, DO: 3.96 - 4.65mg/L, nitrate: 0.45 - 0.58 mg/L and phosphate: 0.36 - 0.56 mg/L. Based on the abundance of pyhtoplankton, it can be concluded that the Samsam peat swamp water can be categorized as oligotrophic.Keyword : Phytoplankton, Samsam Peat Swamp, Water Quality and Oligotrophic

Abstract

The research was conducted in December 2016-January 2017 in the mangrove ecosystem of Sungaitohor Village, Riau Province. The objective of this research was to analyze the biomass potential of mangrove ecosystem, to know the difference betwen above ground biomass potential (Above Ground Biomass, AGB) and underground biomass (Below Ground Biomass, BGB). Of the ANOVA test results on the levene test count has a value of 5.822 with a probability value of 0.009 (<0.05) then the three variants of the population are identical so that the biomass content of Station 1. Station 2 and Station 3 is not significantly different, the results showed that in the t-independent test results showed no significant differences in the potential value of AGB and BGB. Based on the ANOVA test the finding shawed no significant difference to total biomass at each station in Sungaitohor Village, Meranti Islands District.Keyword : Mangrove, Biomass, Sungaitohor, Meranti

Abstract

ABSTRACTThis study was conducted on June to October 2017 in the Laboratory of Parasites and Fish Diseases, Fisheries and Marine Science Faculty, Riau University. The objective of this research was to understand the best of Lawsonia inermis L. solution for immersion in preventing the  of Aeromonas hydrophila infection. There were five treatments applied namely negative  control (Kn) was the fishes were not infected with Aeromonas hydrophila and were not immersed with Lawsonia inermis L. solution, positive control (Kp)  was the fishes were not immersed Lawsonia inermis L.  solution but were infected with Aeromonas hydrophila. The dose of Lawsonia inermis L. solution were 2000 ppm (P1), 3000 ppm (P2), 4000 ppm (P3). The fish was immersed for five minute in once a week for five times immersion. The result shown that the immersing with Lawsonia inermis L. solution in 2000 ppm (P1) was the best dose with a total value of erythrocyte 1.92x106 cell/mm3, 37.33% of hematocrit and 7.80 g/dL of hemoglobin and  the survival rate  (P1) was 93,33 % .Keywords: Lawsonia inermis L., Pangasius hypophthalmus, Aeromonas hydrophila, erythrocyte, hematocrit

Abstract

This research was conducted in February 2017 in Koto Mesjid Village, Kampar Regency, Riau Province. The selection of the location of this research is done deliberately because the village of Koto Mesjid is an area that most of the fish farmers and almost every house has Wi-Fi access so that this village also bears the title of "Digital Village". This research uses qualitative approach. Informants in this research are the fish farmers in the Koto Mesjid village. The Characteristics of the use of cyber extension on fish farmers in the village of Koto Mesjid can be seen from the age of cultivators that is productive age, the level of higher education and the influence of the surrounding environment. The practice of using cyber extension to fish farmers in Koto Mesjid Village is by inter connecting access, internet calling and chatting. Sources of information obtained from several websites, groups and individuals that can be utilized for fish farming. Utilization of cyber extension on fish farmers in the village of Koto Mesjid can be said to be very useful. This can be seen with the existence of cyber extension, fish farmer become very helpful in finding information that can be applied to the aquaculture fishery activities.Key Word: utilization, cyber extention, fish farmer, interconnecting access.

Abstract

This research was conducted in April 2017 by taking samples of sediment and macrozoobenthos from Estuary of Batang Arau River of Padang City, West Sumatera Province. The aim of the study was to analyze the content of organic sediment and macrozoobenthos abundance and the relationship of organic sediment with macrozoobenthos abundance. The method used is a survey method consisting of 4 stations with 3 replications at each station. The results showed that the average content of organic sediment material in Estuary of Batang Arau River is 10.78% and the content of organic sediment material between different stations is significantly different (P<0.01) while the abundance of macrozoobenthos is 12 ind/m2 and the abundance of macrozoobenthos between stations is not significantly different (P>0.05). The content of organic sediment material and macrozoobenthos abundance showed a weak positive relationship with the regression equation Y = 7.024 + 0.461X.Keywords: Organic Material, Abundance, Macrozoobenthos, Estuary, Pollution
