Abstract

Marine pollution is a change in marine environment including estuaries, which can cause bad consequences for marine living resources, danger to human health and reduce the quality of sea water and it’s function. This research aims to know the water quality of Batang Arau River and it’s organic pollution level. This research was held on December 2016 until February 2017 by using survey method. The quality of Batang Arau River is categorized as under adverse conditions. Based on this observation, found many garbage which makes the value of dissolved oxygen are low (DO <5 mg/L) and it’s not eligible for biota’s life. The value of BOD in Batang Arau River ranged from 0.2-2.1 mg/L, the value of COD range from 12.8-53.3 mg/L and the value of TOM ranged from 12.20-22.12 mg/L. The result of ANOVA shows that value of the water quality in Batang Arau River are very different between stations (p<0.001).Keywords: Organic pollution, Batang Arau River, Water Quality

Abstract

This research aims to evaluation and compared chemical proximate composition, amino acid and fatty acid, jelawat fish from different sizes small (400-500 gr), medium (700-800 g), and large (1000-1100 g). Jelawat fish used is 27 from cage in Kampung Jelawat, Kampar. Value of jelawat fish was evaluation, value of edible portion, processing waste, water holding capacity, sensory quality, proximate, amino acid and fatty acid. The research was showed that appearance, odor, edible portion, processing waste was not different between fish size. The highest flavors, texture is found in large sizes fish. The highest water holding capacity is found in medium size fish then large size fish and small size fish. Water content and ash content from large size fish was highest, then followed in a row by medium size fish and large size fish. The protein content of medium size fish is higher than small size fish and large size fish. The highest amino acid is found in large size fish followed by small size fish and medium size fish. The highest fatty acid is found in small size fish followed by medium size fish and large size fish.Kata kunci : Leptobarbus hoevenii, psychochemical and sensory, from different sizes.

Abstract

This research aims to determine the effect of “Attack” detergent addition at different concentration and exposure time on heterotrophic bacterial growth in sea water. The research was conducted from February to April 2017 used experimental method. The results showed that the highest number of heterotrophic bacteria was observed on the A5 day 1st exposure treatment of 6,69 x 107 (CFU/ml) and the lowest was in the 16th day of exposure treatment of 0,098 x 107 (CFU/ml). At day 1st, the value of the correlation coefficient (r) obtained by 0.277 showed the relationship between two variables with positive linearity, while day 6th to day 21th, the correlation coefficient (r) are 0,982, 0,9426, 0,9778 and 0,986, showed the relationship between moderate two was very strong variables with negative linearity. The regression relationship between exposure time and bacterial growth showed a strong correlation with negative linearity, where the coefficient value (r) was 0,87. Significant treatment of detergent concentration that was equal to 0,00 and exposure time that was equal to 0,00 < α (0,05). The bacterial growth on treatment A1 (control) was significantly different with treatment A2, A3, A4 and A5. Bacterial growth at day 1st was significantly different from 6th, 11th, 16th and day 21th. The result of this research showed that there were a effect of “Attack” detergent addition with different concentration and exposure time to the growth of heterotrophic bacteria in seawater.Keyword: Detergent, Concentration, Exposure, Growth, Heterotrophic Bacteria

Abstract

 ABSTRACT This study was aimed to effect of addition of pandan leaves (Pandanus amaryllifolius) extract on carrageenan pudding and produce carrageen pudding which has the distinctive color and odor of Pandan leaves on the manufacture of carrageen pudding and to find out the exact concentration of Pandan extract in the manufacture of carrageen pudding. Based on the research, the effect of addition of pandanleavesextract on carrageen pudding gives the color and the peculiar odor of pandan leaves, very significant effect on organoleptic value, water value, ash value, and carbohydrate value. The treatments were treated with 4 treatment levels: P0 (without pandan extract), P1 (30 ml of pandan extract), P2 (35 ml of pandan extract), P3 (40 ml of pandan extract). The results of selected carrageen pudding was the addition 40 ml of pandan extract with value of appearance (very greenish) 8.41, taste (sweet) 7.24, aroma (very fragrant of pandan aroma) 7.88, texture (solid) 7. 53, and chemical values of water content 19.27%, ash content 3.31%, and carbohydrate content 33.99%. Keywords: Pandanus amaryllifolius, pudding, carrageen

Abstract

Phytoplankton is a microscopic aquatic organisms that has limited movement. A research aims to determine types and abundance of phytoplankton has been carried out on December 2016 in the Parit Belanda River. There are three stations namely Station 1 (in the upstream), Station 2 (in the middle) and Station 3 (in the downstream). Samplings were conducted once/week for 4 weeks period. Water quality parameter measured were temperature, transparency, pH, DO, CO2, nitrate and phosphate. Phytoplankton was identified. Result shown that there are 53 types of phytoplankton and they are belonged to 7 classes, namely Bacillariophyceae (17 species), Chlorophyceae (18 species), Cyanophyceae (9 species), Cryptophyceae (1 species), Crysophyceae (1 species) Dinophyceae (3 species), and Xanthophyceae (2 species). Phytoplankton abundance in the Parit Belanda River range from 1,836 – 2,675 cells/L. Water quality parameters were as follows: temperature 28.25-29 oC, transparency 34.4-46.25 cm, pH 5-6, DO 1.95-4.42 mg/L, CO2 32.96-54.95 mg/L, nitrate 0.076-0.137 mg/L, and phosphate 0.194-0.264 mg/L. Based on the abundance of pyhtoplankton, the Parit Belanda River can be categorized as oligotrofic.Keywords:Parit Belanda River, Pyhtoplankton, Oligotrofic, Riau, Water quality.
