Abstract

The area around the Parit Belanda Riverhas been used by human activity. Remains of the activity may enter the water and decrease the water quality of the river. To understand the water quality of the Parit Belanda River, a research was conducted in March-April 2016. There were three sampling stations namely Station 1 in up stream, Station 2 in the middle of the stream, and Station 3 in down stream. Samplings were conducted 4 times, once/week.Water quality parameters measured were temperature, transparency, velocity, pH,DO,CO2,nitrate and phosphate.Results shown that temperature: 29-30oC, pH : 5, DO:3.15-3.96 mg/L, CO2: 22.98-56.93mg/L,velocity : 0.9-0.27 cm/second, transparency: 30.75-38.75 cm, nitrate: 0.13-0.21 mg/L, and phosphate 0.25-0.33 mg/L. Nitrate concentration indicate that the Parit Belanda River was categorized as oligotrophic, but base on phosphate concentration indicate that the Parit Belanda River is mesotrophic.Keywords : River , Parit Belanda River, Water Quality, oligotrophic, mesotrophic

Abstract

ABSTRACTPeriphyton is a microscopic organism that lives attached to a submerged substrate. This study aims to determine the trophic status based on periphyton on a glass substrate at Lake Perupuk conducted in June-July 2019. There are three sampling stations, namely S1 (at the inlet lake), S2 (in the middle of the lake). lake) and S3 (at the end of the lake). Sampling is done once / week for 3 weeks. Periphyton samples were brushed from glass substrate (8 x 3) cm2. The number of media in S1, S2 and S3 is 24 pieces each. Water quality parameters measured are brightness, temperature, pH, dissolved oxygen, free carbon dioxide, nitrate, and phosphate. The results showed that there were 29 types of periphyton found consisting of 5 classes, namely Bacillariophyceae (11 species), Chlorophyceae (7), Cyanophyceae (6 species), Zygnematophyceae (3 species) and Euglenaphyceae (2 species). The abundance of periphyton in the glass substrate at S1 on the surface was 8,763 cells / cm2, at S2 it was 11,939 cells / cm2 and at S3 on the surface was 21,339 cells / cm2. Water quality parameters are as follows: oxygen range: 5.32-6.40 mg / L, CO2: 5.99-15.98 mg / L, temperature: 28-30 0C, brightness: 44.3-49.3 cm, pH: 5, phosphate: 0.0125-0.0646 mg / L, nitrate: 0.0553-0.2146 mg / L. Data obtained shows that the quality of perupuk lake water is suitable to support periphyton life.    Keywords : Type and abundance, sessile organism, aquatic algae, glass

Abstract

Periphyton is one of microorganisms that serve as primary producer in the aquatic environment. The periphyton contain Chlorophyll-a that is used for photosynthesis activity. To understand the concentration of Chlorophyll-a in glass substrate the Salo River, a study has been carried out in April-May 2015. The Chlorophyll-a data are used as a basis to calculate the primary productivity in the Salo River. There were 3 stations, in each station the water and periphyton were sampled once/week, for a 4 weeks period. The number of glass sampled in each station is following Berkman and Canova 2007, there are 30, 15 and 9 pieces in Stations 1, Stations 2 and Stations 3 respectively. The periphyton samples are brushed from the surface of glass substrate (10 cm x 3 cm). The chlorophyll-a concentration in the glass substrate ranged from 2.574 mg/m2 – 5.514 mg/m2. The chlorophyll-a concentration indicates that the trophic status of the Salo River is oligotrophic.Keywords : Salo River, Periphyton, glass substrate, chlorophyll-a

Abstract

Periphyton is a group of microorganisms that grow in some natural subsrates such as rock, wood, plants and aquatic animals. A research aims to understand the type and abundance of periphyton at smooth surface glass and rough surface glass in the Parit Belanda River has been carried out in March-April 2016. There are three station namely station 1 up stream, station 2 in the middle of stream, and station 3 at down stream. Sampling once/week for a 4 weeks period. The periphyton samples were brushed from the surface of glass substrate (8 cm x 3 cm). Type of periphyton was identified based on Bigg and Killroy (2000), Yunfang (1995) and Prescot (1974). Result shown that there are 36 types of phytoperiphyton are belonged to 4 classes, namely Bacillariophyceae (17 species), Chlorophyceae (10 species), Cyanophyceae (8 species) Rhodophyceae (1 spesies), whereas zooperiphyton are belonged to 5 classes, namely Monogononta (9 spesies), Euglenophyceae (3 spesies), Crustacea (1 spesies), Adenophprea (1 spesies) and Insecta (1 species). The abundance of phytoperiphyton attached in the smooth surfaced glass was 18,790-25,230 cells/cm2 and the zooperiphyton was 1,400-2,540 organisms/cm2. While the rough surfaced glass, it was 20,780-30,450 cell/cm2 and the zooperiphyton was 1,280-1,470 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, Glass Substrates

Abstract

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
