Abstract

Indonesia the outbreaks of disease in red spotted fish is caused byA.hydrophila bacteria. Many efforts have been made by the experts to address thisoutbreak by both giving vitamins and giving probiotics and antibiotics. However aprolonged uncontrolled usage and improper dosage may lead to negative impactsto the species. Thus, the use of medicinal plants or fitofarmaka is a solution toovercome these problems. This research aims to know the effectiveness ofFrangipani leaf extract (Plumeira rubra) on the growth of bacteria A. hydrophilaand to determine the minimum dose of Frangipani leaf extract necessary to inhibitthe growth of bacteria. The research was conducted at Laboratory of FishQuarantine, Quality Control and Fisheries Product Safety Level I, Medan I. Theresearch used a completely randomized experiment method with 6 treatmentlevels and 3 replications. The research shows that, the Frangipani leaf extractdoses has highly significant effect on the growth of bacteria A .hydrophila, andthe minimum dose to inhibit the bacteria is 2 % with a clear zone diameter of 6.4mm.Key words : Effectiveness , Frangipani leaf extract, A. hydrophila

Abstract

The Purpose of Lake Toba were very diverse and required water qualityand fulled certain requirements. Otherwise, the used of the lake for the variousactivities of the society also gave impact to water quality degradation. Thisresearch were conducted from May to July 2013 in Lake Toba. This research usedPurpossive Random Sampling. There were 3 locations. Station I: Ajibata area,Station II: Haranggaol area and Station III: Porsea as the outlet of Lake Toba.Sampling activities were conducted once/month. This research aimed to knewheavy metal consentrate of Lead (Pb) and Copper (Cu) in water and sediment.This results showed indicated chemical physics parameter of Lake Tobastilled in the normal range. Concentrations of copper (Cu) in the water column ateach station in sequence 0.027 mg/l, 0.025 mg/l, 0.033 mg/l and the concentrationof lead metal (Pb) in the water column 0.039 mg/l, 0.014 mg/l, 0.029 mg/l. Whilemetal concentrations of copper (Cu) in sediments at each station in sequence1.092 mg/kg, 2.85 mg/kg, and 2.483 mg/kg and the concentration of lead metal(Pb) of 3,058 mg/kg, 3.592 mg/kg and 2,833 mg/kg. These results indicated theconcentration of heavy metal Cu and Pb in the water column had exceeded thequality standard, while concentrations of Cu and Pb in sediments had notexceeded the quality standard.Keyword: Cuprum (Cu), Lead (Pb), Toba Lake, Water Quality

Abstract

Binahong leaves are one of natural product to be used to treat the diseaseof living organisme due to having secondary metabolite to show antibacterialactivity. The purpose of this research was to study secondary metabolite ofBinahong leaves of which showing antibacterial, to analysis effectivity ofantibacterial Binahong leaves extract to inhibit growth of bacteria Aeromonashydrophila. An experimental laboratory with six treatments and three replicationsfor in vitro was tested. A paper disc soaked in a solution of Binahong leavesextract was used for in vitro at a concentration of 0% (w/v); 0,2%; 0,4%; 0,6%;0,8%; positive control (Oxytetracycline). In vitro test showed that Binahongleaves extract inhibited the growth of bacteria A. hydrophila with a inhibitionarea around the paper disc. Diameter Inhibition area that formed was 0 mm ( 0 %negative control ), 8.4 mm (0.2 %), 9.4 mm (0.4 %), 10.5 mm (0.6 % ) ; 11 , 9 mm(0.8 % ), 27.5 mm (positive control). The increase concentration of Binahongleaves extract enhanced the growth inhibition area. Phytochemical screening ofBinahong leaves extract showed that the extracts contained flavonoid, phenol,saponin, alkaloid, steroid/triterpenoid.Keywords : Binahong leaves, Aeromonas hydrophila, flavonoid, phenol, saponin,alkaloid, triterpenoid, β –sitosterol

Abstract

Coastal area constitute appointment room between continent and ocean. Coastal area constitute ecological unique area because this region have natural resources potency which can be developed as tourism area. One part of the coastal area which is not developed as tourism area is Talugawu Beach at North Nias Regency. Therefore, need to do an analysis by looking at the existing conditions at the beach. Analysis which is used in this research is descriptive analysis, analysis of suitability land for beach tourism recreation category, analysis of community participation and SWOT analysis. Talugawu beach have an attractive natural beauty. From the results of questionnaire, the community around the Talugawu beach has a fairly high involvement in the development of Talugawu beach tourism potential. From the result of suitability land analysis, acquired the value of suitability tourism of Talugawu beach included on S2 category is suitable. From the result of SWOT analysis, acquired the result calculation of IFE and EFE matrics showed above 2.50.Keywords : Coast region, tourism area, SWOT analysis, suitability land analysis, natural beauty, Talugawu beach

Abstract

Aquaculture of Catfish has several advantages, such as rapid growth, high ability to adapt in environmental, and high nutritional content. Nowdays, most of the African catfish aquaculture used intensive farming systems. One of important factor for catfish aquaculture pests and diseases. Disease problems are usually a major obstacle because it can harm aquaculture such as total mortality, productivity and in water quality. One of the diseases that often attack the catfish is A. hydrophila bacterium. This research had been conducted on September – November 2013. This reseach intend to identify and determine spreading of the bacterium A. hydrophila in catfish especially in Medan Tuntungan Sub-district. This research used sampling method, bacterial diagnosis and identification of bacteria. The result showed, from 90 isolates, 19 of them infected by A. Hidrophila bacteria, that was 7 species in pond I, 0 species in pond II, 7 species in pond III, 3 Species in pond IV, 2 species in pond V.Keyword : Cathfish (Clarias batrachus), Bacteria Identify, Types of Bacterias, Aeromonas hydrophila Bacterium.

Abstract

Mangrove ecosystem at Kuala Langsa has been used as one of the tourist area which offer tourism to get closer to nature. At this area had built shelters in the middle of the mangrove forest. Futhermore, there are rivers used as a fishing area, and mangrove forests which still inhabited by monkeys makes potentially used as a mangrove ecotourism.This study was conducted in June until July 2013 and held at mangrove areas of Kuala Langsa at District of West Langsa, Langsa, Province of Aceh. This research using analysis vegetation of the mangroves, tourism suitability analysis, analysis of ecotourism attraction, analysis of the economic value and SWOT analysis.Kuala Langsa mangrove ecosystem inhabited by 5 species are Rhizophora apiculata, Rhizophora mucronata, Xylocarpus granatum, Brugueira gymnorrhiza, Scyphipora hydrohyllaceae. Greatest density of mangrove species is Rhizophora apiculata. Index of ecological suitability for tourism activities in the mangrove Kuala Langsa included into the category corresponding conditional. This category has the limiting factor which shows that to make this site as the location for ecotourism, protection of mangrove ecosystem in order to balance and prevent biodegradation of mangrove that cause damage is important thing to do.Keywords : Ecotourism, Kuala Langsa, Mangrove, Potency.
