Abstract

ABSTRACT Guava (Psidium guajava L.) is one of medicine plant which leaf has all kind of purpose. Guava leaf contains alkaloid, flavonoid, tanin, saponin and etherial oils which effect to kill mosquito larvae. The purpose of this research is to know the effectiveness of guava leaf extract as an Aedes spp. mosquito larvacide in ovitrap and the value of LC50 within 24 hours. This study is a quasi experiment. The method of research using Completely Randomized Design which consist 6 concentrations of guava leaf extract (0 ppm, 500 ppm, 2.500 ppm, 4.500 ppm, 6.500 ppm and 8.500 ppm) by 4 times repetition. Seven hundred and twenty (720) mosquito larvaes are used in 100 ml solution of guava leaf extract. Observation times of Aedes spp. mosquito larvae mortality are 2 hours, 12 hours and 24 hours. Data was analized using Friedman and Kruskal Wallis test with 95% of credibility and probit analysis. According to statistics result indicates average difference of Aedes spp. mosquito larvae death in various guava leaf extract concentration and all time observation is showed by p-value < 0,05. The result of probit analysis showing that LC50 of guava leaf extract on concentration 2.502,67 ppm. As larvacide, the toxicity of guava leaf is safe for non-target organism. The conclusion of this research is guava leaf extract contains chemical substance which can be used as larvacide that most effective on concentration 8.500 ppm (93,33% death percentage) and the amount of the dead Aedes spp. mosquito larvae descended after 12 hours. Guava leaf is expected to be an alternative on Aedes spp. mosquito larvae restraint.

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 Indonesia 70% has caused by motor vehicle emissions that contribute almost 98% of lead into the air. Lead (Pb) is a toxic and dangerous heavy metals that can be toxic to the environment and have an impact on the entire system in the body. Which can be contaminated environment can be air, water, soil, food and others. Vegetables are the example of food that can be contaminated by lead. The objective of this study was to determine the content of lead (Pb) in lettuce and cabbage that sold in Kampung Lalang market Medan based on the distance of trade locations from the highway. The research method is descriptive survey. The examination using Atomic Absorption Spectrophotometer. The study found that the highest lead levels found in lettuce that sold at trade location 0 meter from the highway before washing in the amount of 1.43 mg/kg, once washed lettuce levels of lead decreased to 1.07 mg/kg, and lettuce which closed the levels of lead of 0.69 mg/kg. The highest lead levels in cabbage  that sold at trade location 0 meter from the highway before washing in the amount of 0.57 mg/kg, once washed cabbage levels of lead decreased to 0.39 mg/kg, and cabbage which closed the levels of lead 0.29 mg/kg. The conclusion of this study was the closer the location of trade to the highway, the higher the lead levels found in vegetables. Metal content of lead (Pb) that is checked is still below the threshold limit value requirements established by the Director General of POM Decree No: 03725/B/SK/VII/89 on the maximum limit metal contamination in food that is 2 mg / kg. Traders are advised to pay more attention to the cleanliness of vegetables lettuce and cabbage, for example, provide cover on the vegetables being contaminated by pollutants.
