    Evaluation of the pollution levels of landfill sites - the Landfill Pollution Index (LPI)
    (Environmental Management Society Malaysia, 2004) Theng Lee Chong; Mohd Nasir Hassan; Muhamad Awang; Mohd Yazid Saman
    Most of the solid waste disposal sites in Malaysia are either open dumps or controlled tipping. The pollution levels from these sites are expected to be high especially the contamination of soil, air, surface and underground water. All these pollutions have direct and indirect links to human being. The risks associated with solid waste disposal sites involved three compartments or media, i.e. the atmosphere, water and soil. This "Cross media"or "Multimedia" impacts phenomenon has been recognized in various countries as being of potential importance and complicated. This study discusses the development of a new and simple evaluation system to assess the pollution levels of landfill sites.

    Greenhouse gas emissions during plantation stage of palm oil-based biofuel production addressing different land conversion scenarios in Malaysia
    (Springer, 2017) Faradiella Mohd Kusin; Nurul Izzati Mat Akhir; Ferdaus Mohamat-Yusuff; Muhamad Awang
    The environmental impacts with regard to agro-based biofuel production have been associated with the impact of greenhouse gas (GHG) emissions. In this study, field GHG emissions during plantation stage of palm oil-based biofuel production associated with land use changes for oil palm plantation development have been evaluated.

    Nitrous oxide emission from nitrogen fertiliser application in oil palm plantation of different stages
    (Inderscience Enterprises Ltd, 2016) Faradiella Mohd Kusin; Nurul Izzati Mat Akhir; Ferdaus Mohamat-Yusuff; Muhamad Awang
    The release of nitrous oxide (N2O) from agricultural activities contributes to the increase of greenhouse gases in the atmosphere. In this study, the amount of nitrogen fertiliser used in an oil palm plantation of different stages (immature and mature) was estimated. Data of fertilising scheme at the oil palm plantation for oil palms varying in age (planted between 1986 and 2009) was used. Estimation of nitrous oxide emissions and the resulting CO2-equivalent (CO2-eq) emissions were calculated for each category of the oil palm.
