The used chemically rodenticides to control rodent pest can have a negatively impact on the environment and human life. Utilization of eco-friendly natural materials such as “miang “ Dendrocalamus asper(bambu betung) is one kind of solution that is expected to be used as an alternative material to control rodent pest. This research purposed to determine the effectivenes of “miang” Dendrocalamus asper(Bambu Betung) against mortality of white rats (Rattus novergicus, L.) by used the baits mixed with bamboo miang betung at various concentrations (0%, 5%, 10%, 15%, 20%) on rodent morbidity and mortality rate . The results of this research indicates that mixing the bamboo miang into baits, effect on mortality of rodent. The concentration of 10% of the measure is the most effectivebecause has killed 100% of rats. This research indicates that miang bamboo high toxicity and very potential to be develope as an eco-friendly plant-based rodenticides. Keywords: Dendrocalamus asper,miang, rat, rodenticides, mortality

Indonesia is one nation that has a very extensive tropical forests. Types of diverse plant are largely not been identified promising a great opportunity as a source of useful chemical compounds. Biopesticides are one of the products made from poisonous plants that can be an alternative to the use of chemical pesticides. Biopesticide producing plant species very much and making it relatively easy. By utilizing a poisonous plant as biopesticides, the use of synthetic pesticides can be reduced. This study is expected to be the basis of research methods in the development of poisonous plants in Indonesia. This poisonous plant exploration research aims to identify and analyze the types of chemical compounds of poisonous plants in Gunung Leuser National Park Resort Sei Betung, North Sumatra. The method used is purposive sampling plots with spacious circular plot of 0.05 acres.This research had three phases. The first was aspect local knowledge with survey local knowledge. The second was aspect biodiversity with analysis of vegetation data collection. And the third was aspect phytochemical with detect the contain of secondary metabolit. The kinds of Poisonous plant found in the Gunung Leuser National Park Resort Sei Betung were Hibiscus heterophyllus, Crhysanemum sp., Macaranga denticulata, Macaranga hypoleuca, Pteruspermum javanicum, Artocarpus dadah, Macaranga gigantea, Clidemia hirta. The result of this research showed that all of kinds of aromatic plants contained secondary metabolit. Keywords: Eksploration, Poisonous plant, Phytochemical, Biopesticide.

Data obtained from respondents are tabulated, then used as an analysis to determine the total economic value of forests and to determine the factors that influence it. The total economic value of Tele forest is Rp 806.357.253.000 / year or Rp 11,962,692 / year / ha. Economic values contained in Tele forest is direct benefits in the form of firewood forests, orchids, andaliman and indirect forest benefits such as the value of household water, irrigation water value, the value of carbon sequestration as well as the option value and existence value.
