Abstract

Essential oils are oils derived from plants that are aromatic. Numeg leaves are part of plant that containing essential oil. Each of essential oils from different plants will have different physical properties. In this study, the essential oil is produced using steam distillation method. The purpose of this study was to determine the physical properties of essential oils of nutmeg leaves South Aceh. The physical properties of essential oils can be evaluated from the percentage of moisture content, ash content, aroma, color, and rendemen. The results showed that the essential oil of nutmeg leaves are pale yellow, has a characteristic smell of nutmeg, the percentage of moisture content and ash, viscosity, density is respectively 6.8%, 2.1%, 0.4% yield density, 3.8 P, 0576 g/cm3. The essential oil of nutmeg leaves South Aceh can be used as pharmaceuticals. But the density of leaf nutmeg oil does not comply with ISO Standard.

Abstract

This research was conducted to determine the species diversity of macrozoobenthos and determine the condition of physical and chemical factors in the waters of estuary river in  Nipah Village Perbaungan District Serdang Bedagai Sumatera Utara. The result of diversity of macrozoobenthos obtained 28 species with one phylum, 2 class, 7 orders, 18 families and 20 genera. Measurement of physical and chemical factors waters obtained an average pH 7 both ebb and tide conditions; in conditions of salinity waters receded an average of 0 and at high tide the average of 5; the ebb and tide conditions an average temperature of 27-30°C; Average current speed 10,5-19,1 cm/s; Brightness average water 14-16,3cm; and an average depth of 40,3-150cm. Values obtained by the abundance of species which are 3378-5322 ind/m2. Macrozoobenthos types that dominate the river mouth Nipah are gastropods. Values Diversity Index (H ) macrozoobenthos of 2.152 to 2.762 were classified into well water. Uniformity index (E) showed a value of 0.397 to 0.532 (deployment is not uniform or uneven). Value Dominance Index (C) showed a value of 0.074 to 0.170 (the dominance of low or no kind dominance). In general, relatively good water conditions and suitable for life macrozoobenthos.

Abstract

The purpose of this research was to determine whether there is a relationship of senile cataract with blood sugar levels for people with diabetes who checked in BKIM (Balai Kesehatan Indera Masyarakat) Medan. Research was done through two stages, blood sampling and examination of blood glucose levels and data analysis. The patients blood is taken at any time from the patients fingertip. Data were analyzed calculated the correlation relationship where the cataract as the parameters x and y are the blood sugar levels. Correlation calculation results indicate the number r = 0:46, which means there is less close relationship between cataracts and blood sugar levels but percentages show increased in the percent of patients with both cataracts relation to blood sugar levels as well as cataracts with age. From a study of 60 patients aged 45-65 years who suffer from cataracts are less significant association between cataract with blood sugar levels.

Abstract

The 21st century learning science paradigm is not simply recite facts and understanding the concept but should be able to explain how to build skills to solve problems together. The purpose of this research is to describe; (1)  the granting of aid (schaffolding) by teachers and students to other students who are still in need of assistance in the teaching and learning process, and (2) to describe student behavior after learning over at the SDIT Lukmanul Hakim Langsa about environmentally conscious efforts. The research is used descriptive qualitative methode. Data collecting tool used is a form of observation. The results showed that the importance of environmentally conscious inculcation efforts early on to be done simultaneously and consistently by all stakeholders of the school. The easiest thing is to provide live examples to the students so that they are interested in learning science.

Abstract

This study aims to determine the ability of watercress plants in absorbing mercury (Hg). Mercury is one type of heavy metals dangerous and toxic (Hakim, 2003). If the amount in the water has crossed the threshold will cause pollution. For that required effort to minimize the levels of Hg metal before the waste into the waters, such as by using watercress plants as phytoremediation agent. Research was conducted experimentally. The purpose of this study is to know the ability of watercress in accumulating mercury in water media.Phytoremediation media in the form of HgNO3 solution with concentration 0,5 and 1 ppm and addition of NPK 1 gram in insert plastic container as much as 1 liter. Measurements of Hg concentration in plants were performed on day 5, 10, 15 using SSA. The resulting data is processed using qualitative method of descriptive. The result showed that there was no accumulation of mercury in watercress concentration of 0,5 and 1 ppm during exposure 5, 10, 15 days, and concentration 5 ppm during exposure 5 and 10 days, but accumulated at concentration 5 ppm for 15 days exposure that is equal to 0,116 ppm, therefore watercress is still safe from mercury at low concentration of 0,5 and 1 ppm, but dangerous at concentration of 5 ppm.

Abstract

The levels of Pb, Cu, Cd and Zn in sawi (Barsssica rapa), ground kuna (Ipomea reptans), and spinach (Amaranthus tricolor) in the area of Paya Rumput Titipapan Medan village have been done. The goal is to know the levels of these metals in vegetables grown in the agricultural area of Paya Rumput Titipapan Village. Samples taken randomly in wash drained and weighed. Wet weight then dried at a temperature of 50-100o C for 3 hours, After dry on weigh in gerus until smooth. The sample was destructed with concentrated nitric acid with temperature 80o C, the sample was analyzed by using atomic absorption spectrophotometric (AAS). The results showed the highest levels of lead found in spinach is 6 mg / kg. Levels of cadmium in kale and spinach is 3 mg / kg. While the Cu content on the analysis results are still within the maximum limit. The concentration of Pb, Cd, Zn in each sample exceeds the maximum allowed by the Decree of Dit Jend POM No 03725 / B / SKVII / 89 and SNI 7387: 2009.
