Abstract

River is one of the most important sources of water for human, because it can serve as a source of drinking water, tourism, animal husbandry, and fishery. Positive impact of tourism activities in economic development can also lead to negative effects of environmental degradation. Therefore, a research had been conducted at Betimus River District of Sibolangit, Region of Deli Serdang in June– July 2013 by analyzing the water quality of Betimus Riverand compare it with the water quality standards based on PP No 82 tahun 2001and perceptions of visitors and managers. The Waters quality parameters thatanalyzed, i.e, stream. temperature, brightness, dissolved oxygen,pH, BOD5, ammonis,Colifaecal, and perceptions of visitors. The results showed that water quality value for eight parameters of Betimus River was meet the standard of quality based on PP No 82 tahun 2001 and visitors felt comfortable with these attractions.Key Words :Colifaecal, Betimus River, Tourism, Water Quality.

Abstract

One of the various forms of business which produces fish optimally and do not damage fish populations and environment is a good freshwater fish farming. Currently catfish become one of the leading commodity in the fishery. Bacterial diseases arising from injury affecting the outcome of catfish farming. This research had been conducted on September – October 2013. It purpose was to determine the type of bacterias that commonly found in catfish (Pangasius djambal) wound. Sampling was done one time to collect 10 fishes. Samples were fishes which showed of clinical symptoms such as wound, skin discoloration, defect on the fins, tail and antennae, slow-moving, swim on the surface, tend to be solitary (not clustered ) and also fish without no clinical symptoms. Bacteria only found in injury catfish they are Aeromonas hydrophilla, Pseudomonas aeruginosa, Pseudomonas pseudomallei and Morganella morganii.Keywords: Catfish (Pangasius djambal), Fish disease, Types of Bacterias, Wound.

Abstract

Plankton is aquatic organism that flying and its moves within the water current. Plankton is classified into phytoplankton (classified as plant) and zooplankton (classified as animal). The present of plankton in the water is determined by the physic and chemical condition of the water. Plankton has a limitation to tolerate the environment parameter so, its diversity is different depend on physical and chemical conditions. This research was conducted during April to May of 2013. The sample was taken from four observation stations 4 repetitions. Using Purposive Random Sampling with method. The result of research indicates thast there are 7 class of phytoplankton,they are : Bacillariophyceae, Chlorophyceae, Conjugatophyceae, Coscinodiscophyceae, Cyanophyceae, Eulenophyceae, Ulvophyceae and 12 class of zooplankton, they are : Branchiopoda, Cladocera, Clitellata, Copepoda Crustaceae, Filosia, Gastropoda, Lobosea, Monogonta, Oligotricheae Tubulinea, and Turbellaria The highest total number of plankton is found in station 4 (2043,707 ind/l) and the lowest total number of plankton isfound on station 3 (1519,707 ind/l). The highest diversity index value (H-) for each station is found onstation 3 (1,206) and the lowest on station 4 (0,929). The Pearson correlation of analysis indicates the current, BOD5, phosphate and nitrate have positive correlation to diversity of plankton while temperature, brightness, DO and pH have negative correlation to diversity of plankton.Keywords : Plankton, Asahan River, Diversity.

Abstract

Solution of fabric softener contained cationic surfactant by type quaternary ammonium chloride compounds that harm aquatic life and the environment led to the death of fish. This reaserch intend to determine the level of attack power and influence of fabric softener toxicity to carp seed, this research was conducted on July − November 2013 in the Department of Agriculture and Marine Medan. Stages of testing include : a preliminary test, a definitive test to determine the LC50 until 96 hours and sublethal tests with various concentrations. The results showed of the preliminary test studies have upper threshold value ( N ) of 100 ppm and below the threshold value ( n ) 75 ppm. Test results obtained definitive 96 hour LC50 value of 87.10 ppm. The test results on the highest survival sublethal concentration of 2.61 ppm treatment that is equal to 80 % while the lowest survival at 7.84 ppm concentration and 46.66 %, the highest feed efficiency at treatment concentrations of 2.61 ppm is equal to 4.98 % and the lowest in the treatment of 1.55 % 7.84, and the highest growth rate in the treatment concentration of 2.61 ppm is 0.15 % while the lowest at treatment concentrations of 7.84 ppm at 0.05%. Water quality parameters were observed during the definitive test decreased DO 2.0 − 6.4 mg / l, the temperature increased 27.1 − 30.20C and pH decrease during each treatment concentration of 3 − 6.6 . Water quality parameters at sublethal test that does not decrease drastically DO range 5.2 − 7.6 mg/l, temperature range 27 − 290C and a pH range of 3.4 − 7.5 .Keywords : Fabric Softener, Cyprinus carpio L., toxicity

Abstract

The efficiency of freshwater resources utilization is need to improve in order to increase the production. The purpose of this research is to determine the stocking density of seeds that able to increase Nila growth and survive ability. This research used Nila Gesit with average length in 3,44 cm and average weight in 0,86 gram. Nila gesit was kept in aquarium sized 60 cm x 30 cm x 30 cm, fill with 32 L of water. The research design is complete random plan with 3 treatment and 3 repeatable. The treatment of stocking density are 2 seed/l, 4 seed/l, and 6 seed/l. The results during 28 days are : the highest value 2 seed/l of survival rate (78,65 %), the value of daily growth (3,12 %), and the value of absolute growth (1,07 cm). The result for highest feed conversion in found treatment 3 (6 seed/l) is 4,29. The result has shown that difference of density stock is very significantly affecting rate of daily growth and absolute growth. While degree of survival rate and feed conversion on this research hasnt affected the stocking density. Chemical factor of water quality during the research are : DO (disolved oxygen) 2,8 – 4,9 mg/l, pH 7,1 – 8,6, temperature 26,7 -28,2.Keywords : stocking density, nila gesit, survive rate, growth.

The river is one of the old used by man for a variety of activities in life, with the decline in the quality of human needs and river due to the presence of one of the various waste pollution accidents are heavy metals. This research aims to analyze the content of Pb and water quality standards based on raw fachir PP No 82 of 2001 by using the method tsoret and determine any metal Pb in sediment and ascertaining the quality of sediment based on raw IACD / CEDA. This research was carried out in November-Desember, 2013.The sample using methods purposive sampling by observing three stations. Parameters observed fisika-kimia waters, is the parameter pb on heavy metal concentration and sediments using atomic there water absorption spectrophotometry ( AAS). The level of heavy metals are on board in the highest station of a 0,08 mg / l based by Government Regulation no. 82 of 2001 and the quality of being inducted into a second. Calamity tackling in the metals concentration is found in sedimentary highest station of 2.7 mg / kg, based on environmnetal quality standars iacd / ceda and still classified as low, the sediment yet exceeding quality standards.Keyword : Storet Method and level of pollution Pb in water, sediment, Percut River
