Abstract

The Kampar River received pollutants originated from anthropogenic activities along the river and thus negatively affect the water quality in general. To understand the water quality of the river based on periphyton community structure and WQI-NSF Index, a research was conducted from January to March 2017. There were five (5) sampling points. Water samples were taken 3 times/ week. Water quality parameters measured were temperature, turbidity, transparency, current speed, total suspended solid, depth, pH, DO, BOD5, nitrate, phosphate and types of periphyton present. Results shown that there were 5 classes of periphyton present, namely Cyanophyceae (8 species), Chlorophyceae (16 species), Bacillarophyceae (18 species), Xantophyceae (2 species) and Euglenophyceae (2 species). Water quality parameters are as follows : Temperature 30.3-310C, turbidity 8.1-11.22 FTU, transparency 61.25-79 cm, current speed 25-36 cm/s, TSS 10.3–16.17 mg/L, TDS 11.17– 16.75 mg/L, depth 17-138 cm, pH 5–5.17, dissolved oxygen 5.47– 6.23 mg/L, BOD5 2.59–3.38 mg/L, nitrate 0.0822-0.1803 mg/L and phosphate 0.4352-0.4823 mg/L. The value of the WQI-NSF index was 62-66, indicates that the river is on moderate condition.Keywords : Kampar River, Water Quality, WQI-NSF, Periphyton

Abstract

This research was conducted in April 2016 at the Strait of Bengkalis, Riau Province. The aim of research is to determine the pattern salinity and temperature distribution at ebb tide and flood tide. Research used survey method. Tide data obtained were presented in the form of chat the map and discussed descriptively. Based on the research it showed that average salinity at flood tide 23.56‰ and ebb tide 22.90 ‰. The average of salinity at ebb tide was lower than flood tide. In contrast to the temperature, the temperature measurement at flood tide lower than ebb tide and the average value at flood tide 31,18ºC and ebb tide was 31,53ºC. The results showed that distribution of salinity and temperature during flood tide and ebb tide is fluctuated. The pattern of distribution of salinity, temperature and other environmental parameters (pH, transparency, current velocity and depth) were different betwen the flood tide and ebb tide.Keywords: Salinity, Temperature, Distribution Pattern, Bengkalis Strait

ABSTRACTKampar Kanan River has strong current and rocky substrate and it may affect the type and abundance of phytoplankton and ephylitic periphyton. To understand the type and abundance those organisms, a study has been conducted in February to March 2017. Parameter measured were types and abundance the phytoplankton and ephylitic periphyton, temperature, brightness, current, depth, pH, DO, free CO2, nitrate and phosphate.Samplings were conducted 3 times, once/ week, in 3 stations.Results shown that there were 38 phytoplankton species present, namely Bacillariophyceae (16 species), Chloropyhceae (14 species) , Cyanophyceae (4 species) ,Euglenophyceae (2 species), Chrysophyceae and Dinophyceae (1 species).  The average of phytoplankton abundance was around 2,023to 2,252  cells/L. the H’ was 4.465to 4.624; C was 0.071to 0.115  and E was 0.765to 0.840. Results shown that there were 45 the ephylitic periphyton species present, namely Bacillariophyceae (23species), Chlorophyceae (18species), Cyanophyceae (3species), andXantophyceae (1 species). The average the ephylitic periphyton abundance was 5,322to 8,479  cells/ cm2. The H’ was 3.725to 4.469; C was 0.071to 0.115  and E was 0.765 to 0.840. Based on the abundance of phytoplankton and ephylitic periphyton, the Kampar River in the Air Tiris Village is classified as moderate fertility rate.Keywords: Phytoplankton, ephylitic periphyton, Air Tiris Village Kampar River, Water Quality

Abstract

Mangrove is a tree that normally grows in the intertidal zone of marine coastal environments. This study aims to estimate the carbon content of mangrove forest ecosystems within a certain area, to analyze biomass differences, carbon stocks and CO2 uptake and to analyze the effect of mangrove density on biomass, carbon stock and CO2 uptake. This research held on February 2017 by survey method and used the data of mangrove species, it’s number and diameter of breast height (DBH) on each sub plot. Measurement of mangrove biomass was done allometric equation method. The result of carbon stock and CO2 uptake in mangrove indecates that Station III was higher than Station I and II. The average yield of mangrove carbon stock and CO2 uptake is 1333,99 ton / ha and 4891.30 ton / ha. For the highest soil organic carbon is found in Station 1 with an average soil organic carbon of 1446.75 tons / ha. The density of mangrove biomass, carbon content and CO2 uptake which has a strong relationship. The content of biomass, mangrove carbon and CO2 uptake were significantly different (p <0.05) between stations. Keywords: Mangrove, Carbon, Jorong Ujuang Labuang

Abstract

ABSTRACT This research aim to determine the optimal dose of additional herbal supplements in feed toward the growth performance and survival rate of red tilapia (Oreochromis niloticus) by using biofloc system on peat swamp water. This research was conducted on January 30-March 10, 2018 at Technical Service Unit (UPT) of Hatchery, Marine and Fisheries Faculty, University of Riau. This research was using experimental method by completely random design (RAL) one factor with three replications. The treatments were: A: 0 mL/kg of feed (control), B: 25 mL/kg of feed, C: 50 mL/kg of feed, and D: 75 mL/kg of feed. The herbal supplements were consisted of turmeric, kencur, temulawak and ginger with Bacillus sp. and yeast (Rhizopus oligosporus). The results showed that a different doses of additional herbal supplements affecting the growth performance and the survival rate of red tilapia usingbiofloc system on peat swamp water. In addition, it also affected the absolute weight growth, absolute length growth, feed efficiency and feed conversion ratio.The optimal dose was at 25 mL/kg of feed as it showed significantly different results compared to control and was not differ significantly at higher doses. So that while being applied in terms of economy, 25 mL/kg  was the most efficient dose, by giving the specific growth rate was 2,33%, survival rate was 80%, absolute weight growth was 3,12 g, absolute length was 2,71 cm, feed efficiency was 89,66% and feed conversion ratio was 1,12.                                                                                      Keyword : herbal supplements, red tilapia, biofloc, peat
