Abstract

This research has been done from March to April 2014 in the Bakuok Lake,Aursati Village, Tambang Subdistrict, Kampar District, Riau Province. This research aimsto understand the vertical profil of nitrate in this lake. The research used survey method.The nitrate samples were collected from three station namely station I at inlet of lake,station II in the middle of lake and station III in the end of lake. There were three samplingsites in each station were in the surface, 1,5 Secchi depth and bottom. Sampling was donethree times, once a week. The result shown nitrate concentration in surface : 0,01-0,03mg/L, in 1,5 Secchi depth 0,03-0,06 mg/L and in the bottom 0,05-0,12 mg/L. The nitrateconcentration in surface lower than in the 1,5 Secchi depth and in the bottom and nitrateconcentration increase with the depth. Water quality result shown pH:6, DO: 1,78-5,33mg/L, CO2: 4,66-15,31 mg/L, depth: 208-332 cm, transparency: 74,3-93,7 cm andtemperature: 29,6-30oC. Based on data obtained, it can be concluded the consentration ofnitrate in Bakuok Lake showed the trophic status was Oligotrophic and water quality stillsupport the life of aquatic organisms.Keywords: nitrate, the vertical profile, Bakuok Lake

Abstract

Periphyton is a group of aquatic microorganism that grew in the surface of natural substrates such as rock, wood, plants and aquatic animals. A research aims to understand the periphyton composition in the Salo River was conducted in April to May 2015. Sampling were conducted in 3 stations, they were in the upstream (St1), midstream (St 2), downstream (St 3), 4 times, once/ week. Results shown that there were 42 periphyton species present and they are belonged to 4 classes, namely Bacillariophyceae (28 species), Cyanophyceae (6 species), Chlorophyceae (7 species) and Dynophyceae (1 species). The abundance of periphyton in the upstream, midstream and downstream Salo River is significantly different, there were upstream (630 cell/cm2), midstream (1,499 cell/cm2), and downstream (4,545 cell/cm2) respectively. Periphyton abundance in the Salo River in general was around 630 – 4,545 cells /cm2.Keywords : Salo River, Periphyton, Composition

Abstract

Periphyton is a sessile microscopic organisms that attach on certain substrate. A research aims to understand the biomass of periphyton in the SaloRiver based on its Ash Free Dry Mass (AFDM) in ceramic substrate, a study has been carried out in July-August 2015. There were 3 stations, namely Station 1 (in the upstream), Station 2 (in the midlle part of the stream) and Station 3 (in the downstream) for placing the ceramic substrate and for taking the water samples. Samplings were conducted 4 times, once/week. The periphyton samples were scrapped from the surface of ceramic substrate (10 cm x 3 cm). The number of ceramic sampled in each station were 10, 7 and 5 pieces in Station 1, Station 2 and Station 3 respectively. Results shown that periphyton biomass in the Salo River in general was around 0.449–2.834 mg/cm2. The periphyton biomass in the ceramic substrate placed in the Station 1, Station 2 and Station 3 was significantly different, there were 0.449 mg/cm2, 1.442 mg/cm2, and 2.834 mg/cm2 respectively. In general, the periphyton biomass in the downstream was higher than those of the other areas, indicated that the productivity in the downstream was the highest.Keywords: Salo River, Periphyton, Ceramic Substrate, Biomass (AFDM)

Abstract

Nitrate and Phosphate concentration is related to fertility of the water andthus as a basis determine the trophic status of the waters. A research aims tounderstand the trophical status of the waters of the Solok Pulau lake, an oxbowlake located in the Tanjung Balam Village, was conducted in January-Febuary2015. A purposive sampling method was applied for taking the water sample.There were 4 stations, namely St 1 (in the inlet from the Kampar River), St 2 (inthe middle of the lake), St3 (in the lake inlet from the Tangon River) and St 4 (inthe distanct part of the lake). Samplings were conducted 3 times, once/ week.Water samples were taken from the surface.Results shown that the nitrate concentration was ranged from 0.082 -0.159 mg/L and phosphate 0.023 - 0.033 mg/L, temperature 28 - 29°C,transparency 46 - 53 cm, depth 147 - 297 cm, current speed 3 - 15 cm/s, pH 5.5,dissolved oxygen (DO) 1.29 – 2.17 mg/L. Based on nitrate concentration, thetrophic status of the Solok Pulau Lake was oligotrophic, while based onphosphate concentration, it can be categorized as mesotrophic.Keyword: trophic status, nitrate, phosphate, Solok Pulau lake, oxbow lake

Abstract

The area around the Boko-Boko peat swamp has been used for palm plantation. Remains of fertilizer and pestiside used in the plantation may enter the water and decrease the water quality of the swamp. To understand the trophic status of the Boko-Boko peat swamp’s waters, a research was conducted in March 2016. There were three sampling stations namely Station 1, Station 2, and Station 3 and in each station there were three sampling points, in the surface, 1.5 secchi and in the bottom. Samplings were conducted 3 times, once/week. Trophic status was calculated based on Carlson’s Trophic State Index (TSI). Results shown that the transparency was 49 – 60 m, total phosphorus 0.13 – 0.17 mg/L, chlorophyll-a 3.12 – 6.19 μg/L, depth 45 – 250 cm, temperature 30 - 31ºC, pH 4 – 5, dissolved oxygen 0.41 – 3.26 mg/L, free carbondioxide 7.33 – 21.31 mg/L and nitrate 0.44 – 0.72 mg/L. Based on Carlson’s TSI, the water of the Boko-Boko peat swamp is categorized as moderate-eutrophic.Keywords : Peat Swamp, Boko-Boko swamp, Trophic Status, Trophic State Index

Abstract

 AbstractLubuk Siam lake is an oxbow lake that is located in the Siak Hulu sub-district, Kampar district. There were several human activities around the Lubuk Siam Lake such as agriculture and palm plantation. This study aims to understand zooplankton vertical distribution in that lake and it was conducted in February to March 2017. There were 3 stations, namely Station 1 (inlet area), Station 2 (fish cage area), and Station 3 (outlet area). In each station, there were 3 sampling points: at the surface, 2 secchi depth (126 cm) and 3 secchi depth (189 cm). Water samples were taken once/week for 3 weeks periode. Water quality parameters measured were: temperature, transparency, pH, nitrate, dissolved oxygen and free CO2 . Result shown that total abundance of zooplankton in station I: 945-1680 ind/L, Station II: 1365-2190 ind/L, and Station III: 1.230-2.085 ind/L. Water quality parameters measured were as follow : transparency 63 - 69 cm,  temperature  27.5 – 31.10C, pH 6.83 – 7.27, dissolved oxygen 4.0984 – 7.8399 mg/L, free CO2 5.296 – 15.981 mg/L, and nitrate 0.0694 – 0.1688 mg/L.Keywords: Lake, Lubuk Siam, Zooplankton

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
