Abstract

This research was conducted on April-May 2016 located at Jln. Kamboja No. 38, Simpang Baru, Panam, Pekanbaru. The purpose of this research to determine the population of Daphnia magna were cultured on different media and stocking density that generates the highest population. This research method used is an experimental method. The experimental design used was completely randomized design (CRD) with factorial design 2 factors which consisted of factors A: Media different that Poc Nasa 12 ml/l, Chicken Manure 12 g/l, Elephant Grass 12 g/l, Banana Stem 12 g/l and factor B: Solid different initial stocking 10 ind/l, 20 ind/l and 30 ind/l as many as 12 treatments, 3 repetitions so obtained 36 experimental units. Media and stocking density is very real (P<0,01) effect on the population Daphnia magna. The best treatment of Daphnia magna population during the 20 day study period generated by treatment of K12P30 (Chicken Manure 12g/l+ Stocking Density 30 ind/l) with an average value of 190. While the lowest for the treatment population N12P10 (Nasa 12 ml/l+Stocking Density 10 ind/l) with an overall average of 25 ind/l.Based on the analysis of the content of nutrients nitrogen (N) at the beginning and end of the study the culture medium Daphnia magna there are differences of each culture medium which is to Content Nitrogen (N) at the beginning of the study on media Chicken Manure 1,295 mg/l, Poc Nasa 0,622 mg/l, Elephant Grass 0,414 mg/l, and Banana Stem 0,518 mg/l. while the Content of Nitrogen (N) at the end of the study on Chicken Manure media 1.008 mg/l, Poc Nasa 1,915 mg/l, Elephant Grass 3,326 mg/l, and Banana Stem 0,907 mg/l. Water quality during the study showed a good range for growth of Daphnia magna is Temperatures range between 28,1 - 30,8 °C, DO ranged from 3,1 – 5,8 ppm and pH ranging from 7,1 – 8,5.Keywords : Media, Stocking density, Population, Daphnia magna

Abstract

ABSTRACT Rhizophora sp. is one of the mangrove plant which potentially for antibacterial compound, because it has an alkaloids, saponins, flavonoids and tannins. This research purpose was to know the proper dose of Rhizophora sp. leaves extract in healing the MAS disease (Motile Aeromonas Septicaemia), which can be seen through the leukocytes differentiation of Pangasius hypophthalmus. The method in this research was the experimental method using the Completely Randomized Design (CRD) with one factor, four treatment levels and three times replication. The treatments were P0 (without immersion)and the immersion with leaves extract at dose P1 (1300 ppm), dose P2 (1600 ppm), and dose P3 (1900 ppm). The immersion was implemented twice in 24 hours for about 5 minutes. The fishes were used at 13-15 cm of length for 120 fishes which were infected by leaves extract. The results showed that the immersion of Rhizophora sp.leaves extract at dose 1600 ppm of leaves extract dose could treat the MAS disease (Motile Aeromonas Septicaemia) of Pangasius hypophthalmus. The total average of leukocytes was 69,61×103cell/mm3, leukocytes differentiation was 81,33% of lymphocytes, 9,66% of neutrophils, 9,00% of monocytes. The fagocyte index was 36,66% and the survival rate was 84,61%.Key Words : Leukocytes, Pangasius hypophthalmus,Rhizhopora sp.leaves extract

Abstract

Nirwana Beach in West Sumatera,is commonly used for tourism, fisheries and domestic activities that potential in affecting the water quality. This research aims to determine the relationship between water quality parameters and the phytoplankton abundance in the seagrassecosystem in that beach. Samplings were conducted in September 2016, 3 times, once/ week in 3 stations.          Results shown thatthere were 30 phytoplankton types, consists of five classes, namely Bacillariophyceae (17 spesies), Chlorophyceae (6 spesies), Cyanophyceae(5 spesies), Dinophyceae (1 species) and Xantophyceae (1 species). The abundance of phytoplankton ranged from 12,292 to 23,646 cells/L. the H' was 4.017 to 4.425; C was 0.057 to 0.088 and E was 0.819 to 0.902. Water quality parameters value indicates that it supports the life of phytoplankton. There is a very strong relationship (95%) between the abundance of phytoplankton and water quality parameters. Keywords: NirwanaBeach, Phytoplankton Abundance, Seagrass Ecosystem, WaterQualityParameters

Abstract

In the Koto Panjang Reservoir, the floating net caged fish culture produced organic meterials that negatively affects the water quality. A study aims to understand the concentration of BOD5 in the lacustrine and transition zones has been conducted from March to April 2016. There were 4 sampling sites, in the lacustrine 1 (L1), lacustrine 2 (L2), transition 1 (T1) and transition (T2). The vertical sampling points were decided based on transparency of the waters (at the surface, 3m, 6m, 12m, and in the bottom). The number of vertical sampling sites was depended on the depth of the water. 2 Secchi depth, 4 Secchi depth, 6 Secchi depth and in the bottom of the water. Water quality parameters measured were dissolved oxygen, free carbondioxide, nitrate, pH, phospate, temperature, and transparency. Results shown that BOD5 concentration in the lakustrine zone was 2.92 – 9.34 mg/L and in transition zone was 2.13 – 7.81 mg/L. Two way anova analysis shown that there was no difference in BOD5 concentration between zones. The floating net cage activity influences the BOD5 concentration in the Koto Panjang Reservoir.Keywords: Koto Panjang reservoir, BOD, lacustrine, transition
