(2013-07-23) Kurniawan, Nurmasadi; Budijono; M.Hasbi
This study was conducted in May 2013 in the waters of River Tarai District of Kampar Regency Mines. While the analysis of parameters of BOD, COD, TSS and ammonia performed at the Laboratory of the Department of Public Works, Pekanbaru. This study aims to determine the impact of the disposal of liquid waste on water quality River Village Tarai Tarai district of Kampar Regency Mines aspects of physics (pH, temperature, flow velocity, TSS, depth) and chemical (DO, BOD, COD, Ammonia. From the research this can be concluded that, wastewater effluent know an impact on the physical and chemical quality of river water Tarai as TSS increased, the depth and speed of flow, BOD, COD, pH and NH3. overall impact of discharges liquid waste into the waters of river Tarai still not exceed the assimilation capacity of the river Tarai based on the availability of dissolved oxygen conditions which still meets or is above the minimum requirement of fish life, which is 3 mg /l.

(2013-07-23) Oktafia, Dhela
Trichogaster pectoralis (Anabantidae) is a type of fish that commonly inhabit flood plane of rivers in Riau and it is known as ornamental fish. The biological aspects of this fish, however, is poorly known. To understand the reproductive biology of this fish, a research study has been conducted on Februari to April 2013. Fish samples were captured from flood plane area of the Tangkerang Barat District and Delima District. Parameters measured were sex ratio, GSI, maturity level, fecundity, and egg diameter. There were 87 fishes (32 male and 55 female). The ratio of male and female was 1:2. The GSI of the fish was 0,07-9,58%, egg diameter was relative small (0,48-0,51 mm). The fecundity of fish from the flood plane was3341-22692eggs/ fish. During the sampling period, the maturity level of the fish captured was various, indicate that the T. pectoralis spawning period is relatively long and it peaks in Februari. It is predicted that the T. pectoralis is a parsial spawner.

(2013-06-25) Aswad, Fadillah
Waters around the fish cage culture is rich with organic materials and it is a sufficient habitat for phytoplankton. To understand the types and abundance of phytoplankton around the floating cage area in the Koto Panjang dam, a study was conducted on May – June 2012. There were 3 stations, in the Tanjung Alai (St 1), Batu Bersurat (St 2) and Pulau Gadang Baru (St 3). In each station there were 2 sampling sites, close to the cage and 5 meters from the cage. Samplings were conducted 3 times, once/ week. Phytoplankton was identified based on Sachlan (1980), Davis (1995) and Yun Fang (1995). Results shown that the highest abundance of phytoplankton present in the St 1 (5,360 cells/ ml, 18 species), followed by St 2 (4,162 cells/ ml, 16 species) and St 3 (2,559 cells/ ml, 15 species). Types of phytoplankton around the fish cage culture in general are as follow: Bacillariophyceae (8 species), Cholorophyceae (12 species), Cyanophyceae (7 species) and Xanthophyceae (2 species). The diversity of phytoplankton in the study area are medium (H was 1.74 to 2.06), and there was no dominant species (C was 0.25-0.36). Nitrat concentration in the study area was relatively high, 0.62-1.03 mg/l, and phosphate concentration was 0.03-0.10 mg/l. Based on data obtained, it is concluded that the abundance of phytoplankton in the floating cage area is relatively low.

(2013-06-20) Mayunita, Rizka
The research was conducted from July to August 2012 in Bandar Khayangan Lembah Sari Reservoir. This research aims to understand the vertical profile of dissolved oxygen in this reservoir. Water samples were collected from six station, namely station R.1 and R.2 in riverine zone, T.1 and T.2 in transition zone and L.1 and L.2 in lacustrine zone. In each station, there were three sampling sites namely: in the surface, 2 Secchi depth and in the bottom. Sample was done three time and sampling interval once week. Water quality parameters measured were dissolved oxygen, free carbon dioxide, transparancy, pH, temperature, depth, current, nitrate, phosphate, ammonia and phytoplankton abundance. The result shown dissolved oxygen range 2,40 - 6,83 mg/l, free carbon dioxide 5,33 - 9,32 mg/l, transparancy 47,00 - 55,83 cm, pH 5, temperature 31,0 - 31,7 oC, depth 1,20 - 5,00 m, current 2,61 - 3,06 cm/sec, nitrate 0,01 - 0,09 mg/l, phosphate 0,02 - 0,25 mg/l, ammonia 0,06 - 0,29 mg/l, phytoplankton abundance in the surface range 480 - 936 cells/l, and in the 2 Secchi depth 432 - 904 cells/l. The highest concentration of dissolved oxygen in the surface of riverine zone (6,83 mg/l) and the lowest concentration in lacustrine zone. Based on the vertical profile of dissolved oxygen, it can be concluded dissolved oxygen concentration in lacustrine zone has decreased rapidly due to floating cage activity than the other zones.

(2013-06-04) Melani
Gastropods commonly inhabit mangrove area and it is predicted that there is a relationship between mangrove and gastropod communities. In the Mesjid Lama Village, part of mangrove area has been used for housing and tourism area. As any changing in the mangrove may affects the gastropod communities, a study aims to understand the community of gastropods in the mangrove area has been conducted in December 2012. There were 3 stations namely in the area where most of mangrove has been cut (St 1), in the tourism destination where several mangrove has been cut (St 2) and in the good mangrove forest (St 3). Parameters measured were abundance, diversity index (H'), dominance index (C) and equitability index (E). Results shown that there were 5 families, consisted of Potamididae (3 species), Ellobiidae (2 species), Littorinidae (1 species), Neritidae (1 species) and Assimineidae (1 species). Results shown that gastropod community is related strongly to mangrove density. In the St 3, the density of mangrove (1.722 tree/ha) as well as that of the gastropod (208.889 organisms/ha) are the highest. In contrast, in the St I, the mangrove and the gastropod densities are the lowest (444 tree/ha and 38.889 organisms/ha respectively). Water quality parameters in all stations are almost the same, water pH is 8 and that of the soil is 7.63 – 7.75. Water temperature, however is slightly different, as the St1 (31oC) is hotter than those of the other stations (30,7 oC in St 1 and 29,7 oC in St3).
