Abstract

Belawan River in Lalang Village is the river that contained domestic and market activity. The existence of dumping waste into rivers affecting water quality straight with the level of pollution generated. This study aims to determine the water quality of Belawan river in Lalang Village based on physic, chemical, and biology (makroozoobenthos) parameters. Physic and chemical parameters were analyzed by Storet method, while biological parameters (macrozoobenthos) were analyzed by Abudance and Biomass Comparison (ABC) curve. The study was conducted in January to February 2014. The method used Purposive Random Sampling. Stations are used Station 1 (control), station II (domestic activity), and station III (market activity). Physic and chemical parameters is temperature 26.33 ? 29.00 °C, turbidity (TSS) 8.79 ? 12.99 mg/L, DO 4.37 ? 6.57 mg/L, pH 5.17 ? 6.43, BOD 0.52 ? 0.64 mg/L, nitrate 0.65 ? 0.87 mg/L, phosphate 0.11 ? 0.13 mg/L, abudance and biomass of makroozoobenthos: 0 ? 88% and 0 ? 87%. Based on physical and chemical parameters of water, the station I had score 0 which indicates the water quality is satisfying the quality standard (class I), whereas station II and III had score -10 which indicates water quality is mild contaminated (class II). Biological parameter (makroozoobenthos) produce overlapping curves that show the quality water is medium at each station.Keywords : Belawan River, Lalang Village, Macrozoobenthos, Water Quality

Abstract

Babura River is one of the three river in Medan.Where this river is already contaminated which is caused by the plastic product disposal, disposal of household waste that flowed trough the trenches, and also the disposal of the waste water of the tofu industry. The purpose of this research is to know more regarding how far the effect of the disposal of the waste water of the tofu industry to the quality of Babura River. This research was conducted in August until September 2013 with determining 3 stations. Which every stations divided into three point for water sampling which is taken 100 m from every station. The physic and chemical parameter that is taken for observed are temperature, brightness of the water, Colour, Turbidity, TSS,TDS,DO, BOD, COD, Nitrate, Phosphate and pH.Based on the result of the research using the storet methode we got total score of the each stations in the amount of -29 in the station 1, -22 in the station 2 and -30 in the stations 3 based on the result we can conclude that the contaminations level from the three stations is categorized as c class contaminations which is contaminated with score -11 up to -30.Keywords: Babura river, Storet methods, waste water from tofu industry

Abstract

The rapid growth of water hyacinth and high durability made plant growth is extremely difficult to control. This study aimed to determine the effect of nitrate and phosphate content of the relationship to the gowth of biomass wet hyacinth different locations in the waters Rawa Kongsi during an interval of two weeks. The research was conducted in March to April 2016. Length parameter is water hyacinth plant height, weight parameter consist of fresh weight of water hyacinth, and parameter number consists of the amount of water hyacinth leaves. Water quality parameters measured were dissolved oxygen, pH, temperature, brightness, nitrate and phosphate. The results obtained through the measurement of dissolved oxygen water quality is 1,6 mg/l-4 mg/l, pH is 6,3-6,6, water temperature is 30ºC-32ºC, brightness values is 42-119,5 cm. Nitrate values at Station I, II, and III is 0,25-0,73 mg/l; <0,001-2,09 mg/l; <0,001-2,4 mg/l. Phosphate values at Station I, II, and III is <0,001-0,019 mg/l; <0,001-0,026 mg/l; <0,001-0,032 mg/l. At station III gives better results on the growth of biomass compared to treatment at another location. The highest growth of water hyacinth biomass is found in the observation of the 2nd with biomass wet is 70.6 g and relative growth rate is 3.56% g/day.Keywords : Nitrate, Phosphate, Rawa Kongsi, Water Hyacinth, Wet BiomassGrowth

Abstract

The Rate of Aquatic Primary Prod uctivity (RAPP) is the formation of organiccompounds from inorganic compounds with the aid of sunlight and chlorophyll. KongsiSwamp is stagnant water system utilized by people for agriculture, livestock, fishingand waste disposal that cause a negative effect. This study aims to know RAPP in RawaKongsi and to know RAPP relationship with chlorophyll-a and physical chemistryparameters of water. The study took place from February until March 2016. Thesampling location choosed by purposive sampling which divided into 4 stations basedon different activities. The analysis were method water quality, chlorophyll-a, primaryproductivity and Pearson correlation. The results of water quality analysis showed thatKongsi swamp was moderately polluted based on the average of DO 2,28 mg/L, thevalue average of aquatic primary productivity Kongsi swamp 487,968 mgC/m3/hari,levels trophic based on the value average of chlorophyll-a 2.461 mg/m3 including thecategory of low fertility (oligotrophic). The correlation between primary productivitywith chlorophyll-a and chemical physics of water in Kongsi Swamp is very strong.Keywords: Aquatic Primary Productivity, Chlorophyl-a, Kongsi Swamp, Water Quality

Abstract

Strait of Malacca is a strait that located between the Peninsular of Malaysia (Thailand, Malaysia, Singapore) and the island of Sumatra (Indonesia). The strait of Malacca linked between the eastern part of the Pacific Ocean and the Indian Ocean in the west. The aim of this study was to determine the variability of the concentration of chlorophyll-a and sea surface temperature (SST) as well as its relationship with the catch of tuna (Euthynnus sp.). The method used in this study is a sampling of respondents directly in the field with the interview. The factors of abundance fish Sea Surface Temperature (SST) and chlorophyll-a concentrations, to get the value of SST and chlorophyll-a concentrations using a satellite imagery Aqua?s Moderate Resolution Imaging Spectroradiometer (MODIS). The data of pelagic tuna (Euthynnus sp.) obtained from the Fishing Port Ocean in Belawan. The monthly average of SST in the Malacca Strait from Aqua MODIS satellite imagery in 2009 ? 2014 range between 28,9°C? 32,29°C. The SST of Malacca Strait is following of the wind pattern that occurred in Indonesian water. The highest mackerel tuna catches occurred in the west season and the second transition. The concentration of chlorophyll-a in the research area (2009 ? 2014) of Aqua MODIS satellite imagery in (2009 ? 2014) ranged between 0,59 ? 1,89 mg/m3. The west season is the most dominating of the chlorophyll-a concentration around 1,89 mg/m3. The relationship between SPL and the concentration of the chlorophyll-a by catch tuna showed the negative correlation. In the west and the first transition season, tuna fish has a high correlation to chlorophyll-a and low SST.Keywords : Malacca Strait, Aqua MODIS,Wind, Chlorophyll and Sea Surface Temperature, and Mackarel Tuna.
