Abstract

The river has an important role in the life of every living creature. In his role, the water will affect and are affected by the condition / other components. Water is often contaminated by inorganic components include a variety of dangerous heavy metals. Some heavy metals are widely used in a variety of daily needs and directly or indirectly, can pollute the environment and when it exceeds the limit specified hazardous to life. This study aims to analyze the content of heavy metal lead (Pb) and Copper (Cu) in the central part of Belawan River flow and water quality based Belawan River water quality standards. This research was conducted in March-April 2014 in the district of Medan Belawan River Sunggal Medan. The number of stations observed were 3 stations. Parameters measured were physical-chemical parameters of waters, concentrations of heavy metals lead and copper in the water column were analyzed using Atomic Abrsorption Spectrophotometry (AAS). Concentrations of heavy metals Lead (Pb) in water between 0 to 0.241 mg / l, and the concentration of heavy metals Copper (Cu) between 0 to 0.025 mg / l. This shows the heavy metal content of Pb and Cu in the central part of Belawan River flow has exceeded the standard.Keywords : Heavy metals Pb, Heavy metals Cu, Belawan River

Abstract

Goldfish (Carassius auratus) is a beautiful freshwater ornamental fish. Price of goldfish depends on several factors, one of them is the body color. Goldfish have stable price in the market whether market demand that continues to increase. Goldfish have characteristics from the type of colors and the beauty of their fins. Color is aesthetics ornamental fish that affect it economical values. Thus, the color should be upgraded and maintained its quality. Such efforts to increase color will be done by adding natural pigment into the feeds. Pigments natural resources can be obtained from Spirulina platensis. The purpose of this research is to know dosage Spirulina platensis that optimal to increase the color of Goldfish. This Research using Complete Random Design (CRD) with three repetition, with the dose treatment by 0 %, 1 %, 3 %, and 5 % for up during 28 days. Additional Spirulina platensis through the feed can increasing colors of the Goldfish. The nutrient that enriched with Spirulina platensis dosage 3% can produce colors brighter than the other dose. Additional Spirulina in the feed has no effect on growth of Goldfish.Keywords: Carassius auratus, Goldfish, Spirulina platensis, Color

Abstract

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