Response surface methodology (RSM) was applied to optimize the condition for liquefaction process of Mukah Balingian (MB) low-rank Malaysian coal by using semi-continuous solvent flow two-stage reactor system. The reaction was performed by using tetralin as the solvent. A central composite rotatable design (CCRD) was employed to optimize the effect of three important reaction variables, i.e. flow-rate (ml/min), reaction time (min) and Ni loading (wt.%). A total of 20 experiments were conducted. It was concluded that the liquefaction should be carried out under solvent flow-rate of 1.12 ml/min, reaction time of 60 min and 5 wt.% of NiSiO2 loading. Under the optimum conditions, the corresponding response value for oil+gas yield was 71.25 %.

In the future, OPF is believed to be a very precious raw material since it can be a highly demanded commercial products and renewable energy. Due to this, effective drying method needs to be determined so that the fronds, which currently are left scattering to rotten in most of the oil palm plantations in Malaysia, are not abundantly wasted and they can be dried as to sustain their quality. Therefore, this research investigated the effects of two significant air drying conditions, which are temperature and air velocity, on the drying kinetics of OPF. The experiment used stirred fluidized bed dryer as an alternative to the existing drying methods since it has been proven to be efficient. Different temperatures, which are 60°C, 70°C and 90°C, and the air velocities of 1.45 ms−1 and 1.85 ms−1, were chosen in the experiment. The findings show that the higher the temperature, the shorter the drying time. Furthermore, the air velocity is only significantly effective to the drying rate when the operating air temperature is high.

Previous studies around the world in the field of financing indicate that the small and medium-sized enterprises (SMEs) used more debts rather than equity as a source of external capital. In other words, debt is found to be superior form of financing compared to equity even though credit constraint is still found to have persisted as among the main hurdles to the survival and longevity of the enterprises. The question of whether there is similarity between the stylized patterns of SMEs financing in other parts of the world with that of Malaysian SMEs is something that this study would attempt to investigate. Using descriptive analysis, findings of this study showed that the SMEs in Malaysia are no less different from the rest of their counterparts. One interesting highlight of this study is the fact that a significant number of SMEs sought Islamic financing modes such as Murabahah, Bai' bithaman Ajil and Ijarah as sources of external capital. This could give positive signal for the Islamic financial institutions to offer more of such facilities to the SMEs.

Poly[2-methoxy-5-(2'-ethylhexyloxy)-(p-phenylenevinylene)] (MEH-PPV) was obtained via the modified Gilch route. The expected polymer was obtained in an overall yield of 19.5%. The structures of all synthesized intermediates and MEH-PPV fully complied with their respective spectroscopic data using 1H and 13C nuclear magnetic resonance (NMR) and Fourier transform infrared (FTIR) spectroscopies. Thermal properties of the polymer was studied using simultaneous thermogravimetry and differential scanning calorimetry (TGA/DSC) and morphologies by transmission electron microscopy (TEM). The glass transition temperature, Tg, of MEH-PPV was obtained at 85 °C. TEM results showed that the material was amorphous. Results showed that pure MEH-PPV exhibited high impedance at room temperature but the impedance increases in the MEH-PPV/MCMB composite. The MEH-PPV/MCMB composite film shows an increase in conductivity of the order of 2. The enhancement of conductivity of MEH-PPV by the addition of MCMB was attributed to the change in morphology of the film and contribution of electrons by carbon in the polymer matrix.

A field study was carried out to evaluate the benefits of insulated roof and insulated ceiling for naturally ventilated buildings in Malaysia. Two identical test cells with dimensions of 4m × 4m × 3m were used as building samples. Both test cells have identical design and were constructed with conventional building envelope. The non-insulated control unit is named as Test Cell A (TCA) while the insulated test unit is named as Test Cell B (TCB). Conductive thermal insulation of R-value 2.22 (m2K/W) and 2.88 (m2K/W) was consecutively installed at the roof pitch and internal ceiling respectively. For each insulation configuration, the outdoor and indoor environmental data for both test cells were concurrently monitored using automated data logging equipments. Data logging duration was five days for roof pitch insulation and ten days for ceiling insulation. This paper presents the findings on thermal impact on the non-insulated Test Cell A and insulated Test Cell B. These are appraised by the respective indoor temperature. The finding shows that pitch insulation and ceiling insulation lower the daytime indoor temperature up to 0.8°C and 0.6°C respectively. However, both have adverse impact at night. It is concluded that both pitch and ceiling insulations are beneficial to reduce the day-time thermal impact. The impact is more significant with the pitch insulation. Due to the nominal temperature differential to determine the benefits on the thermal comfort conditions, a cooling load analyses could further substantiate the advantage and disadvantage of the insulation.

A study on the formation of ZnO nanostructures using the carbothermal evaporation method without catalyst and at atmospheric argon pressure has been conducted. The effects of the position of the substrates to the source and deposition time were investigated. The results of these parametric studies based on field-emission scanning electron microscopy (FESEM), Energy dispersive X-ray spectroscopy (EDX) spectrum and X-ray diffraction (XRD) analyses support the reduction-evaporation model for ZnO nanostructures formation using carbothermal evaporation. We suggested that ZnO nanostructures that have been synthesized in this work have potential applications in solar cells.

Oil palm fronds (OPF) which were collected from Sime Darby Oil Palm Factory Merlimau, Melaka can be used as substrates for the cultivation of various microorganisms for the production of different products which are important for industrial application via solid state fermentation (SSF), particularly for this research, xylanase enzyme. SSF is generally defined as the growth of the microorganisms on solid material in the absence or near absence of free water. Fungi are attracting greater interest than bacteria as potential sources of plant cell wall hydrolyzing xylanases because they secrete high levels of the enzymes into the culture medium. Thus, a fungi namely Aspergillus niger (obtained from the Microbiology Laboratory, University Selangor) was used to degrade the hemicelluloses (found in the substrate) and produce xylanase as the secondary metabolite. Xylanase can be used in the food and beverage, feedstock improvement, kraft pulp bleaching, in poultry industry, de-inking of newspaper and agricultural waste degradation. Three fermentation parameters were studied in the research, namely fermentation days, moisture content of the fermentation medium and carbon source. The best day for the optimum xylanase production was in day six with the enzyme activity of 0.6506 U/min. Meanwhile, 70% of the moisture content gives the highest enzyme activity of 0.624 U/min and carbon source from sucrose gives 0.624 U/min of xylanase activity compared to other carbon sources.

In this paper a validated, generic and user-friendly PV array and MPPT models are presented in the mathematical modeling and circuit-based approach. The PV array model accepts irradiance and temperature as variable parameters and outputs I-V and P-V characteristics. The Hill Climbing (HC) algorithm is implemented to track the maximum power point (MPP). The model is validated against data obtained from an installed PV system at Malaysia Green Technology Corporation (MGTC) in Bangi, Selangor, Malaysia with installed capacity of 47.28 kWp. From the comparison of the simulated results with that of the MGTC, it clearly shows that power produced in simulation is higher than the actual. This is due to some factors itemized in this work.
