    Removal of malathion using selected granular activated carbons
    (Terengganu: Universiti Malaysia Terengganu, 2013-09) Hajjar Hartini Wan Jusoh
    The usage of malathion pesticide and a subsequent release into the environment was a major concern worldwide due to detrimental effect and their toxicity to ecosystem. Some studies showed that granular activated carbon (GAC)becomes the most effective adsorbents for the removal of pesticides. Therefore, a study was carried out to investigate the potential and effectiveness of four different types of granular activated carbon (GAC) namely coal base, coconut shell, palm shell and peat base to remove pesticides particularly malathion.

    Wind energy assessment for selected sites in Malaysia and the proposed feed-in-tariff rates
    (Terengganu: Universiti Malaysia Terengganu, 2013-11) Aliashim Albani
    Wind energy is still not recognized as eligible energy resource in Malaysian Renewable Energy Act 2011. There are only four technologies applicable for Feedin-Tariff (FiT) which are biomass, biogas, solar and small hydro. Thus, there is no Feed-in-Tariff (FiT) for the wind projects in Malaysia. This thesis presents the identification of Feed-in-Tariff (FiT) based on the Annual Energy Production (AEP) at every selected site: Kuala Terengganu, Mersing, Kudat and Langkawi Island. WindPRO and WAsP software are used for the energy simulation. The wind data are obtained from the Malaysian Meteorological Department (MMD) stations. The Pitch 22 kW wind turbine was selected for energy simulation due to its best capacity factor compared to the other type of wind turbines. Forty six different installed capacity wind farm in range 22 kW till 1.012 MW were simulated based on the 22 kW wind turbine, sites roughness condition and sites wind resources. The Feed-in-Tariff (FiT) is identified by Net Present Value (NPV) analysis, Payback Period (PBP) analysis and degression rate analysis. The result found that the proposed FiT rates are based on the value of NPV is 98.6% from the investment cost with payback period is 10 years. The best degression rate is 5% for every year.

    Properties of chemically modified alpinia galanga filled hdpe composites
    (Terengganu: Universiti Malaysia Terengganu, 2014-05) Rohani Mustapha
    In recent years, many studies have focused on the idea of using natural fibers from renewable resources as alternative to replace traditional synthetic fibers in polymer composite systems. This is due to the increased ecological concern and environmental awareness. In this study, the effect of untreated and sodium hydroxide (NaOH), 3-aminopropyltriethoxysilane (3-APE) as well as p-toluenesulfonic acid (PTSA) treated Alpiniagalanga (AG) agricultural residue-HDPE composites with and without addition of maleic anhydride-graft-polyethylene (MAPE) and eco degradant (ECO) were studied. The composites were prepared by melt blending HDPE resin with various AG fiber loadings (3, 6, 10 and 15 wt%) by using a BrabenderPlastograph EC mixer at 135°C at 50 rpm. The composites were characterized based on tensile properties, morphology, thermal properties and water absorption. The finding reveals that AG fibers generally reinforced AG/HDPE composites with increasing AG fiber loadings. Four formulations of AG/HDPE show a significant improvement in tensile strength. Tensile strength of NaOH and 3-APE treated AG fibers/HDPE composites with an addition of ECO (AG/HDPE+ECO) is 34.7 MPa, which is 24.9 % higher than that of pristine HDPE (27.8 MPa). The addition of AG fibers improved the Young’s modulus of AG/HDPE composites with addition of ECO up to 4874.2 MPa as compared to HDPE (1012.7 MPa). However, the elongation at break of AG/HDPE is generally lowered with the inclusion of AG fibers. The treatment of AG fibers with NaOH and 3-APE and inclusion of ECO resulted in 0.4 % water absorption than that of HDPE(0.1%). The presence of treated AG fibersshowed higher the thermal stability of AG/HDPE composites compared to untreated AG/HDPE composites. Thetensile fracture surfaced morphology of AG/HDPE composites and Fourier transform infrared spectroscopy(FTIR) analysis of untreated and treated AG/HDPE composites with and without addition of ECO and MAPE support the above analysis.

    (Terengganu: Universiti Malaysia Terengganu, 2014-07) Wan Almaz Dhafina Che Wan Ahmad
    Nowadays, earth is facing the depletion of energy resources such as petroleum, natural gas and coal. Apparently, most of these resources produce harmful waste, endanger the living things on earth and this lead scientist to search a new way to substitute this conventional energy sources. Photovoltaic devices provide clean energy that can reduce world's dependency on this conventional energy sources. Tandem solar cell is a type of thin film solar cells which two solar cells were stacked together in means to improve the solar cell's performance. In preparing the tandem solar cell, multilayer coatings are crucial steps and the most appealing technique to fabricate the layers via spin coating.

    Modification of magnesium hydride properties by catalysts and desdestabilizing agent for solid state hydrogen storage
    (Terengganu: Universiti Malaysia Terengganu, 2015-01) Nurul Shafikah Mohd Mustafa
    Solid state hydrogen storage has been an attractive option due to the high gravimetric hydrogen capacity and favourable safety considerations compared with compressed and liquid hydrogen storage. Among the solid state materials, magnesium hydride is one of the potential candidates for hydrogen storage material. The major drawbacks of magnesium hydride are the slow absorption and desorption kinetic and high temperature required for efficient hydride decomposition.

    The Development Of A New Approach To Determine The Suspended Sediment Variability
    (Universiti Malaysia Terengganu, 2015-03) Abd Rahman Bin Mat Amin; Ocean Engineering
    The presence of suspended sediments (SS) along the coast and estuaries are mainly derived from river flow, tidal currents and ocean waves. In large quantities, the SS can alter the ecosystem of the area by limiting the level of light penetration into the deeper seabed. Recently, a number of algorithms have been developed to distinguish SS influenced area and clear water regions in coastal water areas but these algorithms require complicated computational analyses. Thus, a simple method is needed to accurately detect the presence of SS temporally and spatially needs to be developed. This study was conducted to detect the region that affected by SS along coastal line and estuaries by using remote sensing technique. In order to detect the region that affected by the SS on a daily basis, a simple algorithm that based on empirical technique was developed. The algorithm is based on the difference in the slope of the line connecting the wavelength of 0.47 µm to 1.24 µm and the line connecting 0.47 µm to 0.66 µm.

    Study on the characteristics of capillary plasma antenna array in radio wave
    (Terengganu: Universiti Malaysia Terengganu, 2015-05) Noor Fadhilah Ramli
    Recently the new type of plasma antenna shows explosive increment in the antenna development which demands the new elements, the new designs and wide band of resonance frequency in microwave range. Hence, a new approach solution such as the small radius capillary tube with specific gas pressure and the line array pattern emerged to fulfill the requirement of plasma antenna especially wide band microwave range. Some designs of capillary tube with different radius such as 2.0 mm, 4.0 mm, 6.0 mm, 8.0 mm and 10.0 mm that contained the mixture mercury-argon gas pressures, 10 Torr and 20 Torr are created by using CST Microwave Studio.

    Integration of MFA, LCA and GIS and GIS as a simulation decision support tool for biomass agriculture waste management in Terengganu State
    (Terengganu: Universiti Malaysia Terengganu, 2015-10) Latifah Abdul Ghani
    The worsening depletion of nature reserves and the deterioration of environment make the integration of several environmental assessment tools increasingly important and more relevant to be further developed. Terengganu is one of the states in Malaysia with high amount of biomass contents from agricultural wastes that are currently not used as useful resources. Therefore, this study was conducted to evaluate the biomass flow balance from the agricultural wastes in an integrated framework using a combination of Geographic Information System (GIS) and Life Cycle Assessment (LCA) into Material Flow Analysis (MFA) technique. Three parameters were selected to be analysed in the agriculture system of Terengganu, namely Agriculture waste (AgW), Nitrogen (N) and Biomass Energy (BE).
