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

Pesticide poisoning occurs when there is a certain amount of pesticide material that reaches and / or enters the body. Pesticide poisoning is influenced by many factors including dose, amount, time, length, direction and frequency of spray. This study was an observational study using a cross sectional design that aims to determine the effect of dosage, amount of pesticides, PPE usage, direction, time, duration and frequency of spraying on the level of cholesteresterase farmers in Gawu-Gawu Bouso Village, Gunungsitoli Utara District, Gunungsitoli City. The population includes farmers and farm laborers who spray pesticides in Gawu-Gawu Bouso Village, Gunungsitoli Utara District with 44 research samples. Data analysis uses univariate, bivariate (chi-square test) and multivariate analysis with logistic regression. The results of the bivariate analysis showed that there were 6 independent variables that had a significant relationship with cholinestrase namely dose, amount, direction of spray, time, duration and frequency of spray. This is indicated by the significance value of the 6 independent variables is <0.05. Multivariate test results showed that there were 4 of the 7 independent variables that had a significant effect on cholinesterase ie dose, amount, time, and frequency of spray) (p<0.05) while the other 3 variables namely personal protective equipment, spray direction and duration had no significant effect . The most influential variable on colliniestarase is dose.

Abstract

Indonesia memiliki keanekaragaman hayati tanaman yang potensial yang dapat digunakan sebagai tanaman yang mempunyai kemampuan untuk mendegradasi dan mengakumulasi logam berat (hiperaccumulator). Tumbuhan hiperakumulator adalah tumbuhan yang mempunyai kemampuan untuk mengkonsentrasikan logam di dalam biomassanya dalam kadar yang luar biasa tinggi. Penyerapan dan akumulasi logam berat oleh tumbuhan dapat dibagi menjadi tiga proses yaitu penyerapan logam oleh akar, translokasi logam dari akar ke bagian tumbuhan lain, dan lokalisasi logam pada bagian sel tertentu untuk menjaga agar tidak menghambat metabolisme tumbuhan tersebut. Pemulihan lahan tercemar oleh logam berat secara biologi dengan menggunakan tanaman (fitoremediasi). Maka peneliti tertarik mengkaji tentang kajian akumulator tumbuhan air dalam menyerap beberapa logam berat dengan menggunakan metode teknik fotoremediasi. Hasil penelitian  tumbuhan air yang dapat dijadikan tumbuhan akumulator dalam memyerap logam berat yaitu tumbuhan Typha latifolia menyerap logam Cr, Hg, tumbuhan Eichornia crassipes menyerap logam Cr, Hg, tumbuhan Salvinia molesta , tumbuhan Hydrilla verticillata menyerap logam Hg, tumbuhan Ipomea aquatic menyerap logam Hg, tumbuhan hias lidah mertua memyerap logam Pb. Rata rata  tumbuhan air dalam menyerap logam berat  banyak terdapat pada  bagian akar. Tanaman air hyperaccumulator ini telah berevolusi melalui struktur dan fisiologinya, yaitu membentuk jaringan lakuna atau aerenkhima didalam akar dan batangnya untuk pertukaran materi dari bagian batang ke akar. Saat ini walaupun teknologi fitoremidiasi belum banyak diterapkan dalam pemulihan pencemaran tanah dan air, kedepan diharapkan  akan menjadi teknologi pembersih lingkungan yang potensial dengan keanekaragaman hayati tanaman di Indonesia yang dapat digunakan sebagai tanaman hiperakumulator, sehingga program pembangunan yang berkelanjutan (sustainable develeopment) dapat tercapai
