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

Periphyton is a sessile microscopic organism attach on certain substrate. Research aims to determine the type and abundance of periphyton on ceramic substrate has been carried out in April-May 2015 in the Salo River. There are 3 stations (S1, S2 and S3) for placing the ceramic substrate and for taking water samples. Samplings are conducted once/week for a 4 weeks period. The periphyton samples are brushed from the surface of ceramic substrate (8 cm x 3 cm). The number of ceramic sampled in each station is 10, 6 and 3 pieces in S1, S2 and S3 respectively. Results shown that there are 54 types of periphyton present and they are belonged to 5 classes, namely Bacillariophyceae (36 species), Cyanophyceae (8 species), Chlorophyceae (6 species), Dynophyceae (1 spesies), and Xanthophyceae (3 species). The abundance of periphyton in the ceramic substrate placed in the S1, S2 and S3 is significantly different, there were 9,169 cell/cm2 ; 22,002 cell/cm2 and 67,913 cell/cm2 respectively.Keywords : Salo River, periphyton, ceramic substrate, type and abundance

In floating cage fish culture activities, degradation of feed remain and fish feces willincrease the Phosphate content in the surrounding area. A research aims to understand thePhosphate concentration in the water from the cage area and from the area that has no cage hasbeen done from July - November 2014. There were 3 stations, namely 200 m upstream nof thecage area (S1), in the cage area (S2) and 200 m downstream of the cage area (S3). Samplingswere conducted in the DAM site 4 times, once/2 weeks. In each station, water samples werecollected from 3 different depth, surface; 2 secchi and 4 secchi depths. Parameters measuredwere pH, Phosphate concentration, Dissolved Oxygen, transparancy, temperature and depth.Results shown that the concentration of Phosphate in the S1was 0.03 mg/L – 0.13 mg/L; in theS2 was 0.13 mg/L – 0.35 mg/L; and in the S3 was 0.07 mg/L – 0.22 mg/L. The highestconcentration of the Phosphate was in S2, while the lowest was in the upstream (S1). Phosphateconcentration indicates that the DAM site area of the Koto Panjang can be classified aseutrophic, especially in the area around the cage. Other water quality parameter measured weretemperature: 30.6oC – 31oC; transparancy 1.98 m – 2.55 m; depth 27 m – 40 m; pH 5 and freeCO2: 4.66 mg/L- 15.31 mg/L. the values of water quality parameters indicate that the waterquality in the DAM site of the Koto Panjang is good and might be able to support the life ofaquatic organisms in thet area.Keywords: phosphate, cage fish culture,Koto Panjang Dam

Abstract TSI is one of methods used to determine the trophical state of waters. The TSI was calculated based on physical, chemical and biological parameters and it is more representative for analyzing the trophical state of waters.This research was conducted in February-March 2017 and it aims to understand the trophic state of the Lubuk Siam lake. There were three sampling stations namely Station 1 (inlet), Station 2 (pen cage area ), and Station 3 (outlet). In each station, there were three sampling points, in the surface (50 cm), 2 secchi depth (150 cm) and 3 secchi depth (220 cm). Samplings were done once/week for 3 weeks period. Water quality parameter measured were chlorophyll-a, total phosphorus, transparency, temperature, pH, nitrate, and free carbondioxide. Trophic status was calculated based on Carlson’s Trophic State Index (TSI). Result shown that the transparency was 63-89cm, totalphosphorus 0.01–0.23 mg/L, chlorophyll-a 10.27-72.52µg/L, depth 300-700 cm, temperature 27.6-31.1 oC, pH 6.7-7.5dissolved oxygen 4.098-8.264 mg/L,free carbondioxide 3.902 – 15.981mg/L andnitrate 0.054-0.241 mg/L. Based on Carlson’s TSI value, the Lubuk Siam Lake can be categorized as mesotrophic to light eutrophic. Keywords : Lubuk Siam, Lakes, TrophicState Index, Water Quality

This research aims to understand thevertical profile of chlorophyll-a in this lake. The research used survey method. Thechlorophyll-a samples were collected from three station namely station I at inlet of lake ,station II in the midle of lake and station III the end of lake. There were three samplingsites in each station were in the surface, 1.5 Secchi depth and 2.5 Secchi depth. Samplingwas done three times, once a week. The result shown chlorophyll-a concentration insurface :17.26 μg/L -21.44 μg/L, 1.5 secchi depth 11.60 μg/L-14.43 μg/L and in 2.5 secchidepth 9.98 μg/L - 12.41 μg/L. A chlorophyll-a concentration in surface higher than in the1.5 secchi depth and 2.5 secchi depth. The chlorophyll-a concentration decrease with thedepth. Water quality result shown pH:5; DO: 2.60-5.88 mg/L; CO2: 6.79-13.31 mg/L;nitrate: 0.0134-0,093 mg/L; phosphate: 0.03-0.15 mg/L; phytoplankton abundance:3,420,423-4,293,075 cell/L; depth: 180.67-429 cm; transparency: 52.5-54.5 cm;temperature: 28oC-28.34oC. Based on data obtained, it can be concluded the consentrationof chlorophyll-a in Pinang Dalam Lake showed the trophic status was mesotrophic and allwater quality still support the life of aquatic organisms.Keywords : Chlorophyll-a, the vertical profile, Pinang Dalam Lake

Periphyton is a sessile microscopic organisms that are able to attach in some natural subsrates such as rocks, woods, plants and aquatic animals. Research aims to determine the type and abundance of periphyton attached in ceramic substrats in the Parit Belanda River has been carried out in March-April 2016. There were 2 types of ceramics used, the rough surfaced ceramics and smooth surfaced ceramics. There were three stations namely station 1 (in the up stream), station 2 (in the middle of the stream), and station 3 (in the down stream). Samplings were conducted once/week for a 4 weeks period. The periphyton samples were brushed from the ceramic surface (8 cm x 3 cm). Type of periphyton were identified based on Bigg and Killroy (2000), Yunfang (1995), and Presscot (1974). Result shown that there were 63 types of phytoperiphyton present, they were belonged to 5 classes, namely Bacillariophyceae (13 species), Chlorophyceae (10 species), Chrysophyceae (2 species), Cyanophyceae (7 species) Dinophyceae (2 spesies) and zooperiphyton are belonged to 7 classes, namely Cilliate (2 species), Euglenophyta (5 species), Monogononta (11 spesies), Oligotrichia (2 spesies), Protozoa (2 spesies), Rhizopoda (2 species) and Rotatoria (2 species). The abundance of phytoperiphyton attached in the rough surfaced ceramic was 62,370-82,470 cells/cm2 and the zooperipyton was 9,080-53,220 organisms/cm2. While in the smooth surfaced ceramic was 80,200-101,550 cells/cm2 and the zooperiphyton was 16,720-64,320 organisms/cm2. Based on the composition of periphyton, it can be concluded that the Parit Belanda River can be categorized as eutrophic.Keywords: Parit Belanda River, Periphyton, Rough surfaced ceramic and Smooth surfaced ceramics
