Abstract

The research species diversity of fish in estuary waters Karang Gading Wildlife Sanctuary was held in May-June, 2015. It was conducted in three stations by natural zones and utilization. This study aims to determine the diversity of fish species and strong influence parameters with the diversity of fish species in the estuary. The Fish densities were analyzed using the formula Odum (1994). The Diversity Index using the formula Ludwig and Reynolds (1988) and correlation with a diversity index of chemical physics parameters of waters using Pearson correlation analysis with a computerized method of SPSS version 18.00. The results of this study were 19 species of fish. The highest density at station 3 (18,401 ind / m2) and the lowest at station 2 (5,237 ind / m2). The highest diversity index at station 1 (2.35) and the lowest is station 3 (1.62). Current speed, pH, DO and BOD were very strong positively correlated to the value of fish diversity index while the temperature was very strong negative correlation to the index of fish diversity.Keywords : Fish, Diversity, Karang Gading Wildlife Sanctuary Estuary.

Abstract

Mangrove forests in coastal areas physically serves as a barrier of mud and sediment trap. Mangrove are often utilized by people aquaculture activities by means of mangrove forest logging and timber extraction as building materials and firewood, thereby reducing the catch mangrove roots as sediment traps. The purpose of this study was to determine in fluence of mangrove density on the sediment transfort rate in Coastal Pulau Sembilan Village. The research was conducted for two months from March to April 2014 in Coastal Pulau Sembilan Village. The method used is the method of transects and sediment trap method. The results of this study is the highest density of mangrove are found at statiun 4 with a value of 4930 stands/ha and lowest were in station 5 with a value 3662 stands/ha and categorized good. Relationship between the mangrove density and sedimen transfort rate exhibits a negative correlation with a value of -1 this means that sediment rate will be lower when mangrove density higher and vice versa.Key Word : Mangrove Density, Transect Method, Sediment Traps Method, Sediment .Transfort Rate.

Abstract

The mangrove litter which has been decomposed contributes organic matter as source of nutrients, mangrove and natural food source for many species of fish and other organisms in the mangrove ecosystem. The purpose of this research is to know the decomposition of R. apiculata leaf litter and to know the nutrient content of carbon (C), nitrogen (N) and phosphorus (P) in the R. apiculata leaf litter which been released during the decomposition time. This research was done at the waters of the Pulau Sembilan Districs Langkat District Pangkalan Susu, North Sumatra Province during March until June 2016. This research used purposive sampling method at three stations and the determination of the station is done by seeing the availability of R. apiculata at the waters of the Pulau Sembilan. The results showed that the decomposition of R. apiculata litter leaf on day 75 are 8,53 in stasiun I, 8,58 in station II and 10,18 in III station. The fastest decomposition is the station I with 10,18 and the slowest decomposition is the station I with 8,53. The nutrient of carbon during decomposition in 75 days are 17,41% at station I, 15,84% at station II and 17,41 % at station III. Nutrient of nitrogen which beendecomposed on day 75 are 0,98% in station I, 1,18 % in station II and 1,18 % in station III. Nutrient of phosphorus during decomposition in 75 days are 0,08% in station I, 0,09 % in station II and 0,10 % in station III.Keywords : Decomposition, Pulau Sembilan, R. apiculata. nutrient.

Abstract

The development of the technology has driven the growth of industry, on the one side can increase economic growth, but on the other side can lead to destruction of the environment especially marine organisme that fish due to the negative impact of the waste it generates. The objective of the the research are to analize the heavy metal concentration of Pb in sea water and small pelagic fishes (Decapterus sp, Rastrelliger sp and Sardinella fimbriata) landed at PPS Belawan and analysis the correlation of heavy metal Pb in sea water and body of fishes. The research was conducted at Medan Belawan Subdistrict, North Sumatera Province. Analysis of heavy metal Pb content in sea water and body of fishes was carriedout at the Medan Research and Industry Standarization Laboratory. Result showed that the range concentration of Pb in sea water was 0.17 ppm to 0.20 ppm, while in body of fish of Decapterus sp was 0.50 ppm to 1.18 ppm, Rastrelliger sp was 0.24 ppmto 0.97 ppm and Sardinella fimbriata was 0.23 ppm to 0.50 ppm. Compared to Regulation of National Standarization on 2004 the concentration of heavy metal Pb in body fishes had exceeded the level standard of 0.2 ppm. Based on the regresion analysis the correlation (r) of heavy metal contentration in sea water was very strong to heavy metal concentration in body fishes with value 0.73.Keywords : Plumbum, Sea Water, Small Pelagic Fish, Belawan

Abstract

Highly market demand on Mackerel fish (Rastrelliger spp.) effected overfishing without controling by fishermen. The purpose of this research was to determine the potential of sustainable with optimum effort, utilization rates and insistence, sustainability and management of fish resources in Malacca Strait. The analysis of data compresed catches data and fishing effort of Mackerel last 10 years from the Belawan Ocean Fishing Port North Sumatera. The potential of sustainable prediction was performed with Fox model. Value Maximum Sustainable Yield (MSY) Mackerel fish was 6,276,538.129 kg / year with optimum effort was 7939.647596 trips / year. Average utilization rate of 70,39% with an average insistence rate (TAC) 179,49%, while allowable catch 150,1587365 kg/year. Based on the value of MSY and optimum effort Mackerel fish has been overfishing. While based on average utilization rate, Mackerel fish in Belawan aquatic was still in condihtion of solid catch.Keywords : Malacca Strait, Potential, Rastrelliger spp., Sustainability, Utilization

Abstract

Activitieson mangrove areas Bagan Deli Village, Medan Belawan district resulted inwater quality decrease, causing changes in ecological condition of the biota, especiallymacrozoobenthos. This research aims to determine the community structure of macrozoobenthosand water quality based on Abundance and Comparison (ABC) curve. This research was conductedin the mangrove area of the village of Bagan Deli Medan District Belawan from March until April2016. It was done by using purposive random sampling method on three stations. The samplingmacrozoobenthos and watter quality measurement was done and a half month. There were 13species of macrozoobenthoswhich found, namely Telescopium telescopium, Turritella terebra,Nassarius reeveanus, Cerithide acingulata, Chicoreus capucinus, Nerita lineata, Cerithidea obtusa,Littoraria melanostoma, Cassidula aurisfelis, Natica Tigrina, Uca vocans and Uca rosea. Thehighest density is worth 900 ind/dm2. Diversity index was ranged from 1,79 to 2,09 which is in highrated level. Uniformity index was ranged from 0,7 to 0,82 and dominance index was ranged from0,15 to 0,2. The conditional of mangrove area in Bagan Deli village is in the medium pollutedcategory based on the ABC curve.Keywords : ABC curve, Community Structure, Macrozoobenthos, Pollution Levels

Abstract

Lake Kelapa Gading is an artificial lake located in Kisaran Naga district, Asahan. Through the time, Lake Kelapa Gading has been used not only as a rain shelter, but also as a tourism place and floating fish cage. The purpose of this study was to determine the status of water quality of Lake Kelapa Gading. This research used Purposive Random Sampling method by selecting five activity-based-stations on Lake Kelapa Gading. Data were analyzed by using Storet Method and Pollution Index. Water sampling is done by using a modified Van Dorn Water Sampler. The measured parameters were Physics (temperature, TSS, Brightness and conductivity), Chemistry (DO, pH, BOD, COD, Nitrate and Phosphate) and Biology (total coliform). The result of water quality status using Storet Method, based on standard class II and III, scored -30 and -7 of each. The status of water quality using pollution index method, based on class II and III, scored 2.75 and 1.53 of each. Based on the Storet Method, the status of water quality of Lake Kelapa Gading was medium-polluted, while based on the pollution index, it was low-polluted.Keywords : Kisaran, Lake, Pollution, Water Quality.
