Abstract

Toba Lake is a lake that is used as aquaculture land. Floating net cageactivities in the Toba Lake has been done by the public since 1986, but the rapiddevelopment of floating net cage occurred since 1998 through the intensive cultivationnet high fish density. This study aims to analyze potential areas for floating net cage iniToba Lake Girsang Sipangan Bolon, Simalungun by the suitability matrix method. Thisresearch use the scorring method/weighting. Determination of weighting and scoring isdone to put a value on criteria that support the aquaculture activities by linking thechemical physical parameters. These parameters include temperature, DO, pH,brightness, current, depth, BOD, and ammonia. The results showed that thesuitability grade in Toba Lake Girsang Sipangan Bolon is very suitable and suitableclass. This shows that Toba Lake Girsang Sipangan Bolon is a potential area forfloating net cage.Keyword : Toba Lake, Floating Net Cage, Suitability Index

River ecosystems is very important for human life because provide water for human activities such as agriculture, fisheries, industry and domestic. Community activities of agricultural and sand mining activities in the River Ular can be a source of water pollutant that which affect on water quality parameters of physics, chemistry and biology. Water had been studied and compared to the Quality Standard Government Decree No.82 of 2001 by using Storet method. The research was conducted in June 2014 through August 2014 along the River ular from Deli Serdang district boundary to the mouth of the river ular in Muara Pantai Indah. Measurement of water quality parameters was done at 3 stations with 3-point decision. The method used in the determination of water quality sampling station was purposive random sampling. River Ular water quality parameters based on chemicall physics with methods storet showed polluted water to moderate polluted condition. The highest a bundance of plankton found at agricultural area sand the lowest at estuary area. Plankton diversity index values was moderate, low uniformity and there is not dominant species. River Ular water quality based water quality standards according to Regulation No.82 of 2001can be utilized for the fish farming and agriculture to the designation of class III and IV.Keywords: Water quality parameter, Standards Regulation, Storet Method, River Ular

Abstract

Argulus sp. are parasites that act as mediators for viruses or bacteria frequentlycausing diseases by leaving a bite scar. This study was aimed to know potential pathogenicbacterial in the internal and external organs of gourami as result of ectoparasites Argulus sp.infestation. Twelve Argulus sp. were infested on gourami for 14 days. The isolation of thebacterial of the gourami and water was conducted using dilution methods. Bacterialcharacteristic was conducted to their morphology and biochemical properties followed byidentification of the bacterial. Two bacterial species were found in the samples of fish andwater, i.e. Corynebacterium aquaticum and Micrococcus luteus.Keywords : Osphronemus gouramy, Argulus sp., Corynebacterium aquaticum,Micrococcus luteus.

Abstract

Aquaculture is done highly intensive susceptible to outbreaks of diseas. The use of antibiotics in the prevention of bacterial diseases can cause negative effects to human health. Antibiotics can be replaced with the use of plant extracts containing antibacterial compounds, one of which frangipani leaves (Plumiera rubra L.). This study aims to determine the 96-hour LC50 value and safe concentration of frangipani leaf extract of red tilapia fish seeds. The study is divided into two stages, namely the preliminary test and the definitive test. Preliminary test was conducted to determine threshold concentrations above and below the threshold, where the concentration of the preliminary test is 0 ppm, 50 ppm, 100 ppm, 200 ppm, and 750 ppm. Definitive test using a concentration of 0 ppm; 98,40 ppm; 193,65 ppm; 381,10 ppm; and 750,00 ppm were obtained from calculations based on the threshold concentration of 750 ppm and below the threshold of 50 ppm. Percentage mortality of red tilapia in a preliminary test of the lowest to highest concentration of 3,33%; 16,67%; 46,67%; and 76,67%. Percentage mortality converted into the form used in the probit and probit analysis to obtain the 96-hour LC50 value of 510,63 ppm. Safe concentration of 10% of the LC50 within 96 hours, which is 50,2 ppm. In the 96-hour LC50 valuesindicate that the extract of frangipani leaf included in the category of moderate toxicity.Keywords : Plumiera rubra L., Oreochromis niloticus, LC50, phytochemistry

Abstract

This research aims to determine the physical environmental or socio - economic of local community gives more dominant influence to damage the mangrove forest, changes of shoreline has been occurred from 2003 – 2014, changes of shoreline due to the influence of erosion at coastal of Medan and the dominant species of mangrove as retaining abrasion at coastal of Medan. Changes of Shoreline can be seen with the overlay method. This research uses field observation and interview to the local community directly. The results of research shows that socio - economic of local community gives more dominant influence than physical environmental to damage the mangrove forest. changes of shoreline has been occurred from 2003 – 2014 is about 57 meter. Based on field observation, many mangrove forest are converted into farm and many illegal logging has been occurred in the location of research.Keywords : Physical Function, Mangrove, Abrasion, Overlay, Shoreline

Abstract

Tidal flood case is a problem that often happens in coastal areas. This happens because of the surface of the ground low or even the same compared to the surface of sea water. Besides that, this can also happens due to the increase of sea levels so that when there is a tide the sea water will come and flooded the coastal areas. The purpose of this research is to analyze the condition of tide in coastal areas of Medan city in Medan Belawan sub district and provide a map vulnerability to the increase of sea levels in Medan city. The number of increasing sea levels is obtained from the average of increase tidal per year. This number then will be associated with land use data, topography data, population data, and also direct interview with the local residents. After that, VCA method will be used based on PERKA BNPB N0. 2 the year 2012 to acquire the class vulnerability in each village and projected into the form of map with overlay method. The result of this research showed that the inundation area caused by the increase of sea levels always rising. Based from the VCA method and direct interview, resulted that most of vulnerability that happens in Medan Belawan sub district is belong to the high vulnerability. This result is also suitable with map vulnerability made by BNPB that stating North Sumatera is belonging in category of high vulnerability class. Therefore it needs further treatment to decrease the effect of the increasing sea levels.Keyword : Sea Level Rise, Rob, VCA method.

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.
