    Environmental Implication of Dumping Waste on Marine Ecosystem
    (2016-03-31) Dhahiyat, Yayat
    Based on law and government regulation of Republic of Indonesia dumping waste is prohibited. Law No. 32/2009 on the Protection and Management of Environment stated that any person prohibited from dumping deliberate wastes and/or materials to the environment without permission. However some activities on mining and exploration and production of petroleum as well as dredging of port pond activities at Indonesian marine ecosystem still conducted with permission from the Ministry of Environment. There are some potential impact of dumping wastes on marine ecosystem such as physical disturbance to sea bed, physical and chemical disturbance to water column, organism-level effects for example acute/or chronic toxicity, effects on growth and reproduction, ecological/ecosytem level responses, and human resources use for example aesthetic effects.This paper will explain the activities of mining and exploration and production of petroleum at the Indonesian sea and potential effects on marine ecosystem such as sensitive area (coral reef, sea grass bed, mangrove ecosystem), migration of mammal sea, the area of capture fisheries, and transportation lane in the sea. The specific activities of mining is tailing wastes from gold mining, while exploration and production petroleum activites is dumping of drilling cutting, drilling fluid and drilling mud on the sea.

    Potential Research Bioremediation of POPs (Persistent Organic Pollutant) in Indonesia
    (2015-01-27) Rossiana, Nia; Dhahiyat, Yayat
    The Stockholm Convention aims to protect human health and environment from Persistent organic pollutants (POPs). As a country has ratified the Stockholm Convention, Indonesia has obligation to conduct activities with the final goal of reducing and the phase out of POPs. POPs are !2.!lm!lilo comoounds that are resistant to environmental degradation through chemical. biolooical. and ohotolvtic processes. Because of this, they have been observed to persist in the environment, to be capable of long-range transport, bioaccumulate in human and animal tissue, bioaccumulate in food chains, and to have potential significant impacts on human health and the environment. Persistent Organic Pollutants (POPs) become one of the major problems for the environment in the last years. Their properties that can resist in the atmosphere for several years and easy moving over the long area, make this problem become mora serious. Identification of Contaminated site and remediation in an environmentally sound manner, but recently remediation has not been perfomed. In Indonesia, Research bioramediation of organic pollutants have been carried out by researchers at universities and research institutes both LIPI, Pusarpedal, BPPT and other research institutions. Bioramediation Indonesian Forum has been established and its action immediately realized in field applications

    The Stockholm Convention aims to protect human health and environment from Persistent organic pollutants (POPs). As a country has ratified the Stockholm Convention, Indonesia has obligation to conduct activities with the final goal of reducing and the phase out of POPs. POPs are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes. Because of this, they have been observed to persist in the environment, to be capable of long-range transport, bioaccumulate in human and animal tissue, bioaccumulate in food chains, and to have potential significant impacts on human health and the environment. Persistent Organic Pollutants (POPs) become one of the major problems for the environment in the last years.
