Abstract

The decrease in mangrove area by 30-50% over the past half century provides functionally estimates that mangroves will be lost. Utilization of mangrove ecosystems increasingly large can cause loss of quality and physical function of mangroves, it is feared would disrupt ecological conditions and mangrove vegetation. This study aims to assess the condition of mangrove vegetation of density, frequency, dominance and diversity index mangrove species, to study the distribution pattern of salinity found in mangrove areas and examines the relationship between salinity of the mangrove species that dominate in the Mangrove Ecosystem Percut Sei Tuan Deli Serdang. The technique of taking a vegetation analysis performed using line transect sampling techniques or so-called squared (quadrat sampling technique) to determine the three stations that have each 3 plots and taking 30 points in all three observation stations salinity. This study using ArcGIS 9.3 software to create distribution maps of salinity. The results showed that the value of diversity index mangrove tree on the first station is 2.01, at the second station is 1.24 and at the third station is 1.64, so that the third grades of each stations in the criteria for being classified. Overview of the distribution of salinity produces a range of salinity fluctuated relatively small at between 23 - 24.5 ‰, 24.6 - 26.1 ‰, 26.2 - 27.6 ‰, 27.7 - 29.1 ‰ and 29.2 - 30.6 ‰ contained in all three observation stations.Keywords: Vegetation Analysis, Distribution Salinity, Mangrove Ecosystem

Abstract

Mangrove is the living plant community between the sea and the land that was influenced by the tides. West Sentosa Village still has a natural mangrove ecosystem. But, mangrove in West Sentosa Village has long been used by the local community as a source of livelihood especially mangrove forest logging for aquaculture. This research aimed to know the ecological condition, condition of the mangrove waters and gastropod diversity associated with mangrove vegetation. This research is done in February until April 2016. Methode of the research is Purposive Random Sampling method by taking and observing of biotic components which was mangrove vegetation and density of gastropods and the measurement of water quality parameters. There are 11 kinds of mangrove which found in the research location, namely Acrostichum speciuosum, Avicennia alba, Avicennia marina, Bruguiera sexangula, Excoearia agallocha, Lumnitzera littorea, Nypa fruticans, Rhizophora apiculata, Rhizophora stylosa, Sonneratia caseolaris dan Sonneratia ovata.

Abstract

The mangrove litter which has been decomposed contributes organic matter as food source for many species of fish and other organisms in the mangrove ecosystem. This study aims to determine the effect of salinity on the rate of leaf litter decomposition A. marina and to know the nutrient content of carbon (C), nitrogen (N) and phosphorus (P) in the A. marina litter leaf which been released during the decomposition time. This research was done at Hamparan Perak base Deli Serdang sub-district of North Sumatera Province during February until May 2017. The results of the study of leaf litter A. marina at 0-10 ppt salinity level more quickly decomposes. The average weight of the rest of the leaf litter A. marina which decompose at a rate of 0-10 ppt salinity, 10-20 ppt and 20-30 ppt yaitu 1,46 grams, 5,86 grams, dan 6,53 grams.The rate of leaf litter decomposition A. marina at a rate of 0-1 0 ppt salinity, 10-20 ppt and 20-30 ppt was 28.61, 17.68, and 14.97. Carbon levels of nutrients in the leaf litter A. marina ppt salinity level 0-10, 10-20 ppt and 20-30 ppt was 18,61%, 18,97%, and 18,58%. Levels of nutrients nitrogen in leaf litter A. marina ppt salinity level 0-10 ppt, 10-20 ppt and 20-30 ppt was 1,51%, 1,68%, and 1,18% . As well as the levels of the nutrient phosphorus leaf litter A. marina on ppt salinity level 0-10 ppt, 10-20 ppt and 20-30 ppt was 0,58%, 0,52%, and 0,51% respectively.Keywords :A. marina,decomposition, mangrove leaf litter, nutrients, salinity.

Abstract

Organic mangrove material is mostly used as a detritus such mangrove leavesthat fall throughout the year. Organic particles or litter become living places for bacteria, fungi and other microorganisms. The objective research was to measure decomposition and know the nutrient content of carbon (C) nitrogen (N) and phosphorus (P) leaf litter A. alba released during decomposition in Bagan Asahan Village, Tanjungbalai Sub-district of Asahan Regency. The study was conducted from February to April 2017 using purposive sampling method by looking availability of A. alba Bagan Asahan Village. Result of highest carbon nutrient content (C) station I 18,85% lowest station III 11,58%. The highest nitrogen (N) station III 2, 62% lowest station II 2,29%. The highest phosphorus (P) with the same value station III 0,03% lowest station II 0,01%. Highest C/N station results station III 6,44% lowest station II 4,70%. Dry weight of litter decreased period during the 90 days of the highest average station II 21,70 g lowest station II 2,13 g compared with the initial weight of 50%. The highest value decomposition rate between station III 2,81 lowest value 0,52. The highest average value decomposition rate (k) station I e.i. 41,70 lowest station III e.i. 1,66.Keywords: Avicennia alba, Bagan Asahan Village, Decomposition, Element Nutrient, Leaf Litter, Mangrove.

Abstract

The reseacrh aimed to determine reef fish diversity index, uniformity index of reef fish, reef fish species composition, percentage of reef fish and water quality. The research in was conducted on March, 2016, which was located in theJanggi Island NauliTapian Central Tapanuli, North Sumatra. The method used in the research is Underwater Fish Visual Census (Underwater Visual Census/ UVC) on two points of the station with the line length of 50 m and a width transect each to left and right as many as 5 m and three replications, observations had done for 15- 20 minutes.The quality index of reef fish diversity in Janggi Island was low category (H ' ≤ 2.0). Results of analysis of the data for evenness index of target fish, major fish and indicator fish categorized as low (0 <E ≤ 0.5). For the composition of reef fish species were found 30 species and 8 families, the highest analysis contained on major fish at 69%, target fish at 21% and the lowest at 10% is indicator fish.Keyword : Underwater Visual Census, Transect,Reef Fish, Janggi Island, Tapanuli Tengah District

Abstract

The purpose of this research is aimed to get information for the relation of mangrove ecosystem and fishery resources in Langsa City. This research used descriptive method based on land cover, regression and correlation analysis. Types of data used in this research were primary data of observation and interview, secondary data of mangrove fish catching result and mangrove area change from Landsat. The result shown that the mangrove change area of the period from 2011 to 2016 has decreased by 84 ha as well as the production of fishery resources from mangroves was from 2011 amounted to 1,762 tons decreasing became 414.4 tons in 2016. There was a real influence between the change of mangrove forest area to the production of fishery resources as yielding the equation y = 11,82x - 46427 with the correlation coefficient 0,73. Thus, the production of fish, shrimp or crabs is influenced by the area of mangrove forest, and the more extensive mangrove forest, production is also higher.Keywords: fishery resources, mangrove, land cover, Langsa city
