    Assessment of methane emission and oxidation at Air Hitam Landfill site cover soil in wet tropical climate
    (Springer, 2013) Mohammed F. M. Abushammala; Noor Ezlin Ahmad Basri; Rahmah Elfithri
    Methane (CH4) emissions and oxidation were measured at the Air Hitam sanitary landfill in Malaysia and were modeled using the Intergovernmental Panel on Climate Change waste model to estimate the CH4 generation rate constant, k. The emissions were measured at several locations using a fabricated static flux chamber. A combination of gas concentrations in soil profiles and surface CH4 and carbon dioxide (CO2) emissions at four monitoring locations were used to estimate the CH4 oxidation capacity. The temporal variations in CH4 and CO2 emissions were also investigated in this study.

    Development of A Comprehensive Model for Erosion and Sediment Control towards Good Water Governance: UKM Campus as A Watershed Model
    (The Journal of Institution of Engineers, Malaysia (IEM Journal), 2021) Rahmah Elfithri; Md Pauzi Abdullah; Ahmad Fuad Embi; Mazlin bin Mokhtar; Mohd Ekhwan Toriman; Muhammad Barzani Gasim; Sahibin Abd Rahim; Maimon Abdullah; Anizan Isahak; Noor Ezlin Ahmad Basri; Normaizura Maizan
    This study was carried out to develop a whole ecosystem-based erosion and sediment transport control management system of UKM Campus Watershed which is a sub-basin of Langat River Basin catchment. This is done through the development of an Erosion and Sediment Control (ESC) model for the UKM campus watershed that includes localised technology, information and communication system, as well as awareness and community participation for the greening and rehabilitation of UKM Campus.

    Kepekatan Beban Bahan Pencemar Di Alur Ilmu Kampus Ukm Bangi: Kaedah Min Kepekatan Peristiwa (Emc)
    (The Malaysian Analytical Sciences Society, 2012) Haslinur Md Din; Mohd Ekhwan Toriman; Mazlin Mokhtar; Rahmah Elfithri; Nor Azlina Ab. Aziz; Nur Munirah Abdullah; Mohd Khairul Amri Kamarudin
    Beban pencemar air dan luahan sungai adalah antara data asas dalam menentukan kedinamikan sesebuah sungai. Input kualiti air dan luahan lazimnya boleh diperoleh melalui pengambilan sampel air dilapangan ataupun dicerap secara automatik menggunakan simpanan kawalan data. Artikel ini membincangkan beban pencemar kualiti air dan hubungannya dengan luahan (m3/s) menggunakan kaedah Min Kepekatan Peristiwa (EMC) di Alur Ilmu UKM yang berpunca dari hutan Diptorakap Simpan Bangi

    Predicting sediment load and runoff in Geo WEPP Environment from Langat Sub Basin, Malaysia
    (Technoscience Publications, 2016) Mohammad Zahirul Haque; SahibinAbd Rahim; Md. Pauzi Abdullah; Ahmad Fuad Embi; Rahmah Elfithri; Tukimat Lihan; Mazlin Mokhtar
    This study monitors and predicts the sediment load and runoff at the UKM catchment - the Langat sub basin of Peninsular Malaysia using the WEPP software interfaced in ArcGIS 10.2. Within Geo WEPP and WEPP interfaces, TOPAZ algorithm and climate generator (CLIGEN) were used to parameterize the aspects of land cover, slope, climate, soil and topographic data and estimate stochastic climatic parameters respectively.
