Abstract

ABSTRACT Salted fish is one of fishery products that have an important position and also is one of the nine basic foods on a national scale.Curring aims that preserve the fish doesn’t relieves metal properties. Metal properties can not demolished. Metal will dissolved in the water and absourbed by microoganism then eaten by fish and finally that’s happen bioaccumulation and biomagnification so that fish which make processing, it doesn’t relieve metal properties that contained the fish. The method used in this research is descriptive survey. Samples were obtained from salted fish producers in kelurahan Bahari, Subdistrict of Medan Belawan, checked in Health Laboratory, Province of North Sumatra and Center for Research and Industry of Medan.The five samples of salted fish are ikan Lemuru (Sardinella Aurta), ikan Gelama (Pseudoceina amoyensis), ikan Kresek(Trissa mytax), ikan Gembung (Restreluger kenagona), dan ikan Cincaru (Eleutheronema aurta). To determine the content of mercury (Hg) and Cadmium (Cd) is performed by Spektrofotometri Serapan Atom(SSA) method. To result showed that the content of Mercury (Hg) in salted fish produced in Kelurahan Bahari has been qualified according to BPOM in 2009, which is 0.5 ppm. The content of Cadmium (Cd) contained in a salted fish which exceed the NAB set by BPOM, namely Lemuru fish 0.480 ppm.The four different salted that fish are qualify according to BPOM in 2009, which is 0.1 ppm. Society may consume salted fish produced in Kelurahan Bahari with the exposure limit and not constantly

Abstract

ABSTRACT Fresh fish is the type of fish which has the same characteristic as living fish, in shape, smell, taste and texture, hasn’t gone through preserving process or any other further processing. The fish which is taken mostly comes from Belawan Sea, with the size of 1 kg, 0.5 kg an 0.3 kg. One of the closest fish market with the Belawan Sea is KUB (Kelompok Usaha Bersama). The purpose of this research is to find out the content of cadmium (Cd), metal (Pb) and formaldehyde in the fresh fish which comes from KUB Belawan. The method is descriptive survey to analize the content of cadmium (Cd), lead (Pb) and formaldehyde in some fresh fish. The result showed that the level of cadmium (Cd) in tuna fish (Euthynnus affinis) with the size of 1 kg, 0,5 kg and 0,3 kg are 0,04 mg/kg, 0,01 mg/kg and 0,003 mg/kg and in white snapper fish (Lates calcarifer) are 0,01 mg/kg, < 0,003 mg/kg and < 0,003 mg/kg. The result showed that the level of lead (Pb) in tuna fish with the size of 1 kg, 0,5 kg and 0,3 kg are 0,167 mg/kg, 0,131 mg/kg and 0,101 mg/kg and in white snapper fish are 0,140 mg/kg, < 0,0025 mg/kg and < 0,0025 mg/kg. Formaldehyde showed is negative result. Based on SNI 7387:2009 regarding the maximum limit of heavy metal pollution in food product, which was drafted by taking into account the Ditjen POM Decision No.03725/B/SK/VII/1989, the level of cadmium and lead in tuna fish and white snapper are under the treshold limit value which are 0,1 mg/kg and 0,3 mg/kg. The highest level of cadmium and lead was found in fish with the bigger size and the value of formaldehyde in fishes that were taken from KUB Belawan is negative. The fish from Belawan Sea is safe to consume, but it’s better to consume the small size fish instead of the bigger ones.

Abstract

Abstract Air pollution in urban area dominated by as much as 70% by vehicle activity. Carbon monoxide (CO) and sulfur dioxide (SO2) are included as the pollutants that produced by vehicle and also included as air quality parameters. If the concentration in air exceeds the quality standard can cause health promblems for humans. The objective of research would be to know the difference of CO and SO2 concentration in air by virtue of the traffic volume and quantity of tree at Jl. Dr. Mansyur and Jl. Jend. A.H. Nasution in Medan city for 2015. This research used survey and descriptive method in order to know the description about difference of CO and SO2 concentrations in air by virtue of traffic and quantity of tree at Jl. Dr. Mansyur and Jl. Jend. A.H. Nasution in Medan city for 2015. The result of research the highest concentration of CO and SO2 were found at Jl. Jend. A.H. Nasution with the highest traffic volume and less of tree with the number of CO is 17.750 µg/Nm3 and the number of SO2 is 69,93 µg/Nm3, while the lowest concentration of CO and SO2 were found at Jl. Dr. Mansyur with the lowest traffic volume and many more of tree with the number of CO is 9.161 µg/Nm3 and the number of SO2 is 59,05 µg/Nm3. The conclusions of this research is concentrations of CO and SO2 were found on highway with high traffic volume and less of tree. Therefore it would be necessary to grow tree or other plant that can assorb air pollutant on the highway with hectic traffic acitivity.

Abstract

Abstract Aedes spp is vectors of any diseases such as dengue, phylariasis, chikungunya and yellow fever. Control of transmission of diseases is by control the vector of disease. One of efforts is by using toxic synthetic insecticide on human so it need the safe bio insecticide. The method applied in this research is complete random sampling in which the experiment with 3 treatments and one control, the spraying with concentration of extract duku (Lansium domesticum) peel for concentration 0%, 05%. 1% and 1.5% by 3 repetition. The result of research indicates that on the observation during 30 minutes, the number of dead mosquito  is differed  on each concentration. On concentration 0.5% the death  is 42%, concentration 1% is 56% death, concentration 1.5% is 82% the death and on control with concentration 0% there is not the death of Aedes spp. For observation during 24 hours indicates that the death for concentration 0.5%, 1%, 1.5% and 0% is 44%, 62%, 89% and 0%, respectively. The conclusion of this research is the concentration of duku peel extract (Lansium domesticum) that kill the Aedes spp is concentration of 1% with the death of mosquito is 60% in the observation for 30 minutes.
