Antibiotics are commonly used as food additives in broiler farms and their use tends to be excessive regardless and incorrect that can leave some antibiotic residues in chicken meat. The aimed of this study was to analyze on antibiotic residues level amoxicillin and tetracycline in chicken meat sold in Medan. The antibiotic residues analysis was conducted by extracting the antibiotic from chicken meat with water and acetonitrile (2:8, v/v) and detected by high performance liquid chromatography-mass spectrometry detector using C-18 column (4.6 mm i.d., length 30 mm, particle size 1.8 Âµm) at 35 oC, with the mobile phases, 0.1 % formic acid solution in water and 0.1 % formic acid solution in methanol with gradient elution technique at a flow rate of 0.5 ml/minute. The result exhibited that the chicken meat that were collected from five markets in Medan apparently contained antibiotic residues tetracycline . The level of tetracyclin residue in chicken meat was 0.1157-1.4436 Âµg/g, which exceed the maximum level for tetracyclin residue allowed in foodstuffs of animal origin which is 0.1 ug/g.

The nutritional value and biochemical properties of oil are measured by the fatty acids composition in oil and the position of fatty acids (sn-1,2,3) in the triacylglycerol (TAG) molecule. The purpose of this study was to measure the nutritional value based on the fatty acids composition of virgin coconut oil (VCO) and palm kernel oil (PKO), and the position of lauric acid in sn-2. The VCO used was VCO obtained from one of the Pharmacies store in Medan, and PKO from the Oil Processing Plant. The total fatty acid composition was measured by Gas Chromatography. The nutritional value of fat was evaluated by the percentage deviation from 33.33% (ratio: 1: 1: 1) of each group of fatty acid (saturated fatty acids; SFA: monounsaturated fatty acids; MUFA:polyunsaturated fatty acid (PUFA). The distribution of lauric acid in TAG was conducted through hydrolysis by using specific lipase enzymes active at sn-1,3 positions, so that free fatty acids and 2-monoacylglycerol were produced from one TAG molecule. Then free fatty acids were determined by Gas Chromatography. The distribution of lauric acid at sn-2 position was the difference between total lauric acid on TAG before hydrolysis and free lauric acid from sn-1.3 position after hydrolysis. The results showed that PKO nutritional value was better because of the smaller deviation (95.29%) compared with nutritional value of VCO with a greater deviation (118.55%). Lauric acid in sn-2 from VCO and PKO showed that the distribution of lauric acid in sn-2 position was not different,48.33and 48.59%. Keywords: virgin coconut oil, palm kernel oil, composition of fatty acids, sn-2 position, lauric acids

At this time, there is a lot of ready-to-drink drinking water consisting of mineral water and demineralized drinking water such as Reverse Osmosis (RO) both in packets and refills. Drinking water must meet biological, chemical, and physical requirements so that it does not have negative effects on health. One of the chemical requirements is about the main mineral content of calcium and magnesium in drinking water. Based on research results, drinking water with low minerals (usually expressed as low water hardness) if consumed for a long time will cause health problems, for example increasing the risk of several diseases such as cancer, coronary heart disease, and others. Absorption of toxic metals such as Pb will occur if the minerals calcium and magnesium are very low in drinking water. So, if there is a small amount of Pb toxic metals in food, it will be easily absorbed by the body when calcium and magnesium levels are low in drinking water. However, if calcium and magnesium are sufficient in drinking water, the absorption of Pb, both in drinking water and other food, will be inhibited or not occur. Means can avoid diseases caused by these toxic metals. Therefore, the World Health Organization (WHO) determined that the calcium and magnesium content in drinking water each with a minimum requirement is 20 mg of calcium and 10 mg of magnesium in one liter of drinking water. The Indonesian Ministry of Health in 1975 only stated that the maximum calcium content in drinking water was 75 mg / liter of drinking water and there were no minimum requirements. Then the Ministry of Health in 2010 did not include the calcium and magnesium requirements but only the hardness requirements. So low-mineral drinking water will absorb (trap) the minerals present in other foods and dispose of them so that the body lacks minerals in the long run. Water without minerals will also reduce the process of absorption of minerals in digestion, and can even bind minerals from the body if consumed without other food. Low mineral water is not good as drinking water, especially demineralized drinking water that does not contain minerals can cause health problems especially water without minerals such as RO drinking water. The results showed that the levels of calcium (Ca) and magnesium (Mg) in bottled and refilled drinking water in Medan more did not reach the minimum levels of calcium and magnesium, meaning that drinking water was low in minerals. Even more important is that producers of refilled RO drinking water are in Medan (some claim to get permission from the government) and there is even a bottled RO drinking water product which means getting permission from the Drug and Food Control (POM).

Fruits and vegetables are food ingredients that contain a lots of nutrients such as vitamins, minerals and fiber that are needed by the body. Indonesia is a country that is very rich in fruits and vegetables. However, in fact, fruits and vegetables are rarely consumed by people, especially teenagers. Lack of intake in consuming fruits and vegetables can cause the body to lack nutrients such as vitamins, minerals, fiber and an imbalance in the body's acid and alkaline, which can lead to various diseases. The purpose of this community service is to provide counseling and educate students and teachers about the adequate intake of vitamins and minerals from fruits and vegetables to increase immunity in Senior High School students in Tanjung Morawa District. This community service activity was carried out by means of a lecture method by disseminating the activity plan to the children of the Yayasan Pendidikan Pauly Mandiri students, then demonstrations by conducting counseling. Community service activities in general received a very good response and high enthusiasm from students, and several teachers who attended and the chairman of the Pauly Mandiri Education Foundation in Tanjung Morawa asked to be resumed. The results of community service, especially practicing how to create fruits and vegetables by making salads from various fruits and vegetables that can be applied by students and teachers in their daily lives. The enthusiasm of the participants hoped that this outreach activity could be resumed, namely how to make it easier for children to make it easier for children to remember the importance of consuming fruits and vegetables.

This study reported that the sample used in the study was an infusion using fresh coriander leaves samples taken in the Lubuk Pakam area. Several studies have shown that the active components of coriander seeds are essential oils such as sabiene, myrcene, alphaterpine, ocimene, linalool, graniol, decanal, desilaldehyde, trantridecen, petroselinic acid, octadesenic acid, d-mannite, scopoletin, psimena, kamfena and felandren. These components cause coriander to have a good effect as a medicinal component. In previous studies, Linalool is believed to have antioxidant, anxiety, antibacterial (especially gram-positive) and antifungal effects. This activity is suspected because coriander contains secondary metabolites such as alkaloids, saponins, flavonoids, tannins, steroids, triterpenoids, glycosides. So this research was conducted to determine the content of secondary metabolites in coriander leaves by phytochemical screening. Phytochemical screening is a test to determine the class of chemical compounds present in coriander leaf infusion samples. Fourier transform infrared spectroscopy (FTIR) analysis was performed to find the isolating compounds in coriander leaves. The results showed that one secondary metabolite compound was negative in examining steroid secondary metabolites. The results of extract assistance with FTIR showed the presence of saponins with a molecular weight of 873.0 g/mol at a retention time of 19,287 minutes, but the peaks produced were not dominant.
