ABSTRACT. The purpose of this paper was to report and provide evidence of positive development on physics s implementation of an integrated problem-based learning (PBL) approach. This study was performed on a cohort of 28 Physics with Electronics students from School of Science and Technology at University Malaysia Sabah. The sample was trained by the integrated PBL method for 1 semester (i.e., 14 weeks) in a Physics course (i.e., Thermodynamics).

ABSTRACT. Zinc Oxide (ZnO) is commonly known for its wide band gap of 3.2eV -3.3eV.
H of using ZnO for a different functional device such as light emitting diode and solar cells. The objective of this study is to doped ZnO film in order to fabricate homostructural ZnO thin film p-n junctions. In this work, doped ZnO will be fabricate using sputtering method and glass used as substrate with a suitable parameters. The proposed
dopants are aluminium, gallium and nitrogen. Thin film that produced will be analysed and its structure will be examined using X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM) for morphology of thin film, UV-Vis Spectrometer for the optical characteristic and I-V measurement for the electrical characteristics. The presence of dopant will influence the characteristic of thin film produced.

ABSTRACT. In this paper, six empirical models were used to predict and modelling the hourly global solar radiation for 6 months in Kota Kinabalu, Sabah. The measured data I t (hourly global solar radiation) were obtained using a solar instrument, spectrometer. The measured data from the spectrometer is compared with measured data from Sabah Meteorological Department for validation. In order to determine the performance of these models, the statistical parameters such as normalised mean bias error (NMBE), normalised root mean square error (NRMSE), correlation coefficient (r), and a t-test were calculated. The values of I t were predicted using selected models. This kind of modelling is important for future applications such as sizing the various solar energy systems like solar thermal and a stand-alone photovoltaic.
