Abstract

Macrozoobenthos is a living organism attached to the bottom of the water or on the surface of the bottom waters. This study aims to determine the level of macrozoobenthos diversity and water quality based The biodiversity Index This study was conducted in May-June 2015 by using purposive sampling method in five different locations of community activities. The research showed 20 species belonging to the 17 families, 4 orders, and 2 classes. The highest density on the station I found the Anadara cornea species of 171.43 ind/m2, the station II on the Anadara cornea species of 304.76 ind/m2, the station III on the species of Murex trapa amounted to 266.67 ind/m2, the station IV in species Volema Myristica and Anadara cornea of 190.48 ind/m2, the station V on the species Monodonta canalifera of 152.38 ind/m2. The highest diversity index of 2.88 at the station I classified in the level of diversity rate as medium and the lowest at station IV of 2.70 were classified in the level of diversity rate as medium. Uniformity index ranged from 0.92 to 0.96 with the uniformity of species category is relatively evenly distributed. Based on the diversity index is known that the estuarine waters of the Coral Ivory wildlife reserve in the category of medium polluted.Keywords :Macrozoobenthos, Diversity, Pollution Level.

Abstract

Ajibata is one of the tourist area in Lake Toba travelers who declined significantly in recent years.The objectives of this research are determining the effect of the presence of ferry ports and floating net cages to the carrying capacity of the Ajibata waterworks tourist area, knowing the environmental suitability as a tourist destination and knowing the perception of tourists to the carrying capacity of the waterworks environment. The research was conducted from April-May 2016 in Ajibata district which was divided into three (3) stations. The existence of ferry port and floating net cage aquaculture activities have an impact on tourism activities seen through the content of nitrate and phosphate on all respectively < 0.50 and 0.01. Ajibata tour area is still quite suitable as a tourist area with suitability index of 66.66%. Carrying capacity region with the area of 15.476 m2 which is 767 people/day. Tourist adequate attraction of Ajibata tour area seen from the perception of tourists that are 66.66% stated a slight smell, brown waters of 78.57%, 38.46% dissatisfied in touring, lack of tourist facilities 83.33%, 53.84% stated quite comfortable, the accessibility stated as quite easy as much as 66.66%, and 69.23% stated beautiful, so Ajibata is less attractive as the tourist destination to be visited.Keywords: Capability Areas, Tourist Attractions, Keramba Cage, Travel Suitability Index, Ferry Ports

Abstract

Percut Sei Tuan Estuary has 3,820 meters length, is influenced by the tide and the shipping line and tourist activity. Macrozoobenthos diversity and the measurement of physical and chemical factors is one of the parameters used to determine changes in water quality in the estuary Percut Sei Tuan. The purpose of this study was to determine the physical and chemical waters in relation to water quality standards under PP No. 82 of 2001 with Storet method as well as the density and macrozoobenthos diversity. This research was conducted over two months, from March until April 2016 Percut Sei Tuan estuary District of Deli Serdang North Sumatera province. Percut Sei Tuan Estuary is categorized at third class water classificatized that can be used for water recreation facilities, fishing ponds and water tourism and for irrigation. Pollution level belongs to the class C is lightly polluted accordance with Method Storet. Values Index Diversity (H') macrozoobenthos obtained at each research station : station 1 is 1,375, station 2 is 1,444 station 3 is 2,050. These results indicate that the diversity of macrozoobenthos was moderate. Pearson correlation analysis results showed that the temperature, salinity and pH highly correlated, BOD5 classified as moderate, and light penetration is low DO and COD relatively very low correlated.Keywords: Estuaries Percut Sei Tuan, Macrozoobenthos Biodiversity, Water Quality

Abstract

Catfish is consumption fish , with a chewy meat structure, easily separated with its thorns and low calorie content, 120 calorie each 3.5 ounce. Catfish are also used as ornamental fish in the aquarium with a shiny silver body color, as well as agile body movements make catfish widely favored ornamental fish lovers. The purpose of this study was to determine effect of probiotic in addition on growth and feed conversion ratio of catfish. This study used a Completely Randomized Design (CRD) with four treatments, namely, P0 (without the addition / control), P1( probiotic addition 1 g / kg), P2 (probiotic addition 2 g / kg), P3 (probiotic addition 3 g / kg ). The treatment P1 provides a significant influence on weight gain, but no significant effect on the length catfish. The treatment P1 is the best dose for the growth catfish with growth 8,54 cm long value and weight value 7,56 g and feed conversion ratio 0,82.Keyword: Catfish, Growth, Probiotics. FCR

Abstract

Many activities by human and industry in Bagan Deli Village and along the Deli river could be caused the present of heavy metal in acuatiq environmental and could be harm to aquatic organism. The purpose of researching in to analyze the content of heavy metals Cadmium (Cd) and Plumbum (Pb) on roots, barks, leaves and knowing the ability of A. alba in accumulating heavy metals. The sample was located in Bagan Deli Village, District of Medan Belawan. The analysis of heavy metals Cd dan Pb was carried out in a Balai Riset dan Standarisasi Industri Medan, by using the metod Atomic Absorption Spectrophotometry (AAS). The results of this research indicated that the heavy metal content of Pb in the roots, barks, and leaves is larger more than Cd. The result of this research, based on the bioconcentration factor, the ability of A. alba in accumulate heavy metals Cd and Pb categorized low, the average value of BCF Pb was 21,38 and BCF Cd was 3,66. The results of chemical physics parameter in Bagan Deli Village stilled in the normal range. Concentrations of Cadmium (Cd) in the water column at each station in average 0,0013 mg/l and the concentration of lead metal (Pb) in the water column 0,15 mg/l. Concentrations of Cadmium (Cd) in the sediment column at each station in average 0,002 mg/kg and the concentration of lead metal (Pb) in the sediment column 11,38 mg/kg. These results indicated the concentration of heavy metal Cu and Pb in the water column had exceeded the quality standard, while concentrations of Cu and Pb in sediments had not exceeded the quality standard.Keywords : Avicennia alba, Heavy Metal, Cadmium (Cd), Plumbum (Pb), AASPENDAHULUANMeningkatnya industri memberikan dampak

Abstract

Tilapia culture is highly affected by fish diseases, which may be occured because of change in environment. This study was aimed to know potential pathogenic bacteria in nila fish (Oreochromis niloticus). Screening and isolation of the bacteria were done in Balai Karantina Ikan, Pengendalian Mutu dan Keamanan Hasil Perikanan Kelas I Medan I. Identification of the bacteria was conducted using Vitek 2 Compact in RS Murni Teguh. Five potential pathogenic bacteria were found to infect nila fish i.e. Kocuria kristinae and Stenotrophomonas maltophilia of brain, Aeromonas hydrophila of liver, Staphylococcus lentus of kidney and Staphylococcus warneri of skin sample. Water temperature was 32 oC with pH of 6,9 and DO of 2,96 mg/lKeywords : Patumbak, Potential Pathogenic Bacteria, Tilapia, Water Quality.

Abstract

Sili Fish (Family: Mastacembelidae) can be characterized by an elongated proboscis down the snout. Family Mastacembelidae are divided into three genera namely Mastacembelus (61 species), Macrognathus (24 species), and Sinobdella (1 species). The Research on Sili Fish is still limited, even for the North Sumatra region has never been done before. Seruai River is one of the rivers in North Sumatra that obtained Sili Fish populations. This raserch aimed to determine the character of Morphological and Abundance of Sili Fish (Family: Mastacembelidae) in Seruai River. This research was conducted in August 2016. The result showed that Sungai Seruai only have two species of Sili Fish, They are Mastacembelus unicolor (yellow hue on the parallel roundly body, caudal fin separate from dorsal and anal fins) and Mastacembelus notophthalmus (there are black vertical lines on the muzzle area nearby the eye , caudal fin merges with the dorsal and anal fins). The abundance of Sili fish with the use of 0.15 ind/m² and 0.07 ind/m² nets are in station 1 and 3. The abundance value by using 2.13 ind/m² traps is only found in the station 2. The attendance of Sili Fish is very rarely to be found.Keywords : Abundance, Mastacembelus unicolor, Mastacembelus notophthalmus, Seruai River.
