This research aims to study was to determine the effect of various types of active ingredient on mortality Trichogramma sp. In the imago stadia and look for a safe pepticide for Trichogramma sp. In the imago and praimago stadia. Research method using experimental method. Test of pepticide effect on pre-epochal mortality and imago Trichogramma sp. Using the fress method of contact residue. The study was prepared based on Completely Randomized Design with 2 factors and 2 replications. The first factor was the active ingredient of pepticide consisting of 10 treatments namely Lamda Silahotrin 25 gr /L (P1), Dimehipo 400 gr/L (P2), Isoprophilamine Glifosat 480 g/L (P3), Brodifakum 0.005% (P4) , Methyl metsulfuron 20.05% (P5), Triadimefon 200 gr/L (P6), Sipermetrin 50 gr/L (P7), Propiconazole 125 g / L and Tricyclazole 400 gr / L (P8), Cypermethrin 113 g / L ( P9), Annonain (P10).

This research was conducted to determine the type of substrate and its composition in Kampung Nipah ecosystems Perbaungan Serdang Bedagai District of North Sumatra in February to March 2016. Sampling by using the pipe with descriptive methodsÂ and the purposive random sampling technique, while the measured variable is the biology variables that includes physical and chemical factors waters. Physical and chemical factors include pH, salinity, temperature. The study of these types of substrates include gravel, sand is very coarse, coarse sand, medium sand, fine sand, very fine sand, silt and clay. Measurement of physical and chemical factors waters obtained an average pH 7 both estuaries, mangrove rehabilitation and natural; salinity of estuarine waters at 200/00 and the rehabilitation of 280/00 natural mangrove 240/00; average temperature of 29-30Â°C. At the mouth of the river, gravel 0.95%, 97.56% sand and mud of 1.58%, obtained ma sand and mud of 1.58%, obtained mangrove rehabilitation of gravel 0.16%, 93.53% sand, and mud 6.12%, while the natural mangrove 0% gravel, sand 29.88%, 69.89% and mud. So we get the type of substrate on river estuaries nypa and mangrove rehabilitation is the sandy substrate and on a natural mangrove is a muddy substrate.

TheÂ study aimed to determine the effect of chitosan on Â the kidney of rats (Rattus sp.) exposed to lead acetate. Thirty five male animals weighing 250g were divided into 7 groups: Â K group as a control (without treatment), P1Â received Â Pb (40 mg/kg bw as lead acetate), Â while P2, P3, and P4, all received Pb (40 mg/kg bw) and chitosan (0,5%, 0,75%, and 1% respectively). P5 group received only chitosan (1%) and P6 group received acetic acid. After 7 weeks ofÂ treatment, the animals were sacrificed and the kidneys were isolated. Kidney damage was observed with microscopis. Result showed, treatment of Pb (40 mg/kg bw) in male rats caused demage microscopis. Chitosan able to decrease kidney damage resulted from Pb treatment. In conclusion, chotosan has the ability to reduce residue of Pb as well as microstructure damage of rat kidney exposed to Pb.

The potential of Plant as one alternative medicine has been explored. One of the plants that have potential as a drug in inhibiting the fungus is a turmeric leaf. Turmeric leaf have secondary metabolite such as flavonoid, steorid, curcumin, essential oils, tannins. Secondary metabolite are thought to have the ability to inhibit the growth of the Candida albicans. Ethanol extract turmeric leaves used of concentration 10%, 20%, 30%, 40%, 50% and 60%. Each concentration after being tested to Candida albicans has different capabilities in inhibiting fungal growth. The best concentration in inhibiting fungal growth is a concentration of 60% with a mean diameter of the inhibit zone by 7.47 mm. Inhibitor zone that is formed belongs to the medium category. The result obtained showed the higher concentration of ethanol extract of turmeric leaf the the ability to inhibit the groeth of fungis is also getting bigger.
