Abstract

This reseach was conducted to determine the antibacterial activity against Staphylococcus aureus and Eschericia coli from pandanus fragrant ethanol extract formulated in the form of hand gel antiseptic preparations. The ethanol extract was prepared by percolation using 96% ethanol solvent. Phytochemical screening is done on fragrant pandan leaves. Evaluation of hand antiseptic gel preparations included organoleptic testing, homogeneity testing, pH determination, spreading test, stability, irritation testing and antibacterial testing of Staphylococcus aureus and Eschericia coli. The results of phytochemical screening showed that the pandanus fragrant leaves contain alkaloids, tannins, saponins, flavonoids and polyphenols. The pandanus fragrant leaves ethanol extract can be formulated into hand gel antiseptic preparations because the pH is about 6.0-7.1, the spreading power is about 5.06-5.15 cm, stable for 12 weeks and organoleptically a formula with a very 2.5% concentration Favored and does not irritate the skin. The results of antibacterial activity test showed that the preparation with concentration of 10% had the strongest activity with the diameter of 13,23 mm to Staphylococcus aureus and 13,13% to Eschericia coli almost same with dettol stock on the market with diameter 16,43mm to Staphylococcus aureus and 16 , 03% against Eschericia coli.

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.
