Abstract

ABSTRACTSeveral activities in  Bakuok Lake contributed the input of organic and anorganic matter that affects the water quality, especially nutrient concentration in waters. A research aims to understand the trophic state of  Bakuok Lake based on TSI has been conducted in June-July 2019. There were three stations namely station 1 (plantation area), station 2 (residential area) and station 3 (fish cage area).In each station, there were 2 sampling points, in the surface (0.15 m) and 2 Secchi depth (1.74 m). Sampling were conducted 3 times, once/week. Water quality parameters measured were total phosphate, chlorophyll-a, transparancy, dissolved oxygen, CO2,pH and temperature. The value of water quality is as follows: the total phospatewas 0.10-0.22 mg/L, chlorophyll-a12.00-14.43 µg/L, transparency:58-87 cm, dissolved oxygen:6.57-7.54 mg/L, CO2:9.37-13.86 mg/L, pH: 5, temperature:29-31oC and TSI (Trophic State Index) value: 62.54-68.00. Based on TSI value, the Bakuok Lake can be categorized asmoderate to eutrophic.Keywords:Kampar River,Eutrophic, Oxbow Lake, Water Quality

Abstract

ABSTRACTMany activities in the Pekak Lake contribute the input of organic and anorganic matter that affects the water quality, especially nutrient concentration in waters. A research aims to understand the trophic state of the Pekak Lake based on TSI has been conducted in March-April 2018. There were 3 stations, namely in the inlet, midle part of the lake and the end area of the lake. In each station,   there are 2 sampling points, in the surface (0.2 m) and 2 Secchi depth (0.75 m). Sampling were conducted 3 times, once/week. Water quality parameters measured were total phosphate, chlorophyll-a, transparancy, dissolved oxygen, CO2,pH and temperature. Results shown that the total phospate was 0.152-0.508 mg/L, chlorophyll-a 7.061-11.186 µg/L, transparency: 0.69-0.77 m, dissolved oxygen: 5.36-5.96 mg/L, CO2:8.81-16 mg/L, pH: 5, temperature: 27-30oC and TSI (Trophic State Index) value:  64.559-70.465.

Abstract

Abstract Trophic State Index (TSI) is a method 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 analysing the trophical state of waters. This research was conducted in March to April 2018 and it aims to understand the trophic state of the Akap Resevoir. There were three sampling stations namely Station 1 (inlet), Station 2 (in the middle of Akap Reservoir), and Station 3 (outlet). 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 TSI. Results shown that the transparency was 24-30 cm, total phosphorus 0.24-0.54 mg/L, chlorophyll-a 25.56-38.38 µg/L, depth 1.63-2.53 m, temperature29-30 0C, pH 5-5.6, dissolved oxygen 2.95-3.28 mg/L and free carbondioxide 7.99-11.98 mg/L, TSI value 67.55-69.9. Based on Carlson’s TSI value, the  Akap Reservoir  can be categorized as moderate eutrophic. Keywords :Akap dam,Chlorophyll-a, Moderate eutrophic

Abstract

                     AbstractMany activities in the Tanjung Balam Lake contribute the input of organic and anorganic matter that affects the nutrient concentration and increasing the growth of phytoplankton. A research about Trophic State of Tanjung Balam Lakeby Phytoplankton in Buluh Cina Village Kampar District Riau Province has been conducted in June-July 2019. The location of the water samples to measure water quality defined 3 stations, namely in the inlet, the curve of the lake, and in the end of the lake. In each station, there were 2 sampling points, namely in the surface (0.15 m) and 2 Secchi depth (0.90 m). Samplings were conducted 3 times at intervals of a week. Water quality parameters measured were temperature, transparency, depth, dissolved oxygen, CO2, pH, nitrate and phosphate contents. Results shown that there were 61 species of phytoplankton that were belonged to 7 classes, namely Chlorophyceae (23 species), Trebouxiophyceae (4 species), Zygnematophyceae (4 species), Euglenophyceae (14 species), Bacillariophyceae (12 species), Cyanophyceae (3 species), and Cryptophyceae (1 species). The phytoplankton abundance in the Tanjung Balam Lake was 606,144-982,688 cells/L. The most common type of phytoplankton present was Monoraphodium griffithii. Results shown that the temperature was 28-30.3oC, transparency was 49.7-54 cm, depth was 151-236.7 cm, pH was 5, dissolved oxygen was 4.03-6.57 mg/L, CO2 was 3.83-6.13 mg/L, nitrate was 0.016-0.03 mg/L, and phosphate was 0.083-0.108 mg/L. Based on the type and abundance of phytoplankton present, it can be concluded that the Tanjung Balam Lake can be categorized as mesotrophic.Keywords: Kampar River, Oxbow Lake, Mesotrophic, Phytoplankton abundance

Abstract

A study on the strategy of the development of sustainable floating-net cagefisheries in the reservoir of Koto Panjang Hydro-electric Power Plant, Kampar, RiauProvince, was conducted on May-October 2009.. Based on its carrying capacity, thenumber of FNC units which can be exposed in the reservoir during the period of thestudy is 19,599 – 33,515. units. The existing utilization level for 900 KJA is actuallyabout 2.7-4.6 % of the capacity. This indicates that FNC is potential to be develoved.At the time of FNC research with operations in reservoirs are concentrated in theforbidden zone as compared with cultivation zone . The strategy of developmentfloating net cage in reservoir of Koto Panjang for the use of wastes, cultivationtechnology, and environmentally friendly quality feeding, so that the waste from FNCcan be reduced and the adversely impact can be minimized and the reservoir qualitycan be controlled up to floating net cage fisheries in the reservoir sustainable.

Abstract

A study on carrying capacity in the reservoir of Koto Panjang Hydro-electricPower Plant, Kampar, Riau Province, was conducted on May-October 2009. The studyaims to assess the quality and carrying capacity of the reservoir for the development offloating net cages (FNC) units that can be sustainably implementd. Carrying capacity ofthe reservoir was estimated based on P total and dissolved oxygen availability in thewater, while number of FNC was estimated based on the total P availability against thebiomass of fish in the FNC. Based on its carrying capacity, the number of FNC unitswhich can be exposed in the reservoir during the period of the study is 19,599 – 33,515.units. The existing utilization level for 900 FNC is actually about 2.7-4.6 % of thecapacity. This indicates that FNC is potential to be develoved. Regarding the potency ofpollution from Kampar and Batang Mangat river basin (allochtonous sources) and fromthe existing FNC (autochtonous sources) as well as regression analysis of total P contents,it is precdicted that the carrying capacity of the reservoir will considerably decreaseTherefore, it is recommended that number of FNC to be operated in Koto Panjangreservoir should be gradually reduced approximately to 1.32 % a year, up to a minimumnumber of 19,599 units, especially in the potential utilization zone of the reservoir.
