Abstract

Photosynthetically Active Radiation (PAR) is crucial towards crop growth and development, better understanding is needed to determine the relationship between roof mounted PV panels on a PV powered greenhouse and amount of PAR entering the PV powered greenhouse. This study seeks to determine the optimal arrangement of PV module installed on roof of PV greenhouse in terms of Photosynthetically Active Radiation (PAR) available for crops cultivated within PV greenhouse. Three different prototypes were developed for this research, namely control unit without any PV panels installed on roof, straight-line PV array greenhouse and checkerboard PV array greenhouse and data collection was performed for five (5) continuous days. Based on the obtained results, it was found that from the PV greenhouse with straight line PV array allows for highest PAR value within greenhouse, whilst also allowing for PV energy production with minimal compromising on PAR available for crop cultivation.

Abstract

This research paper presents the outcome of research conducted to improve and enhance the creativity level of engineering undergraduates at a private institution of higher learning in Malaysia. A Creative Thinking Module that features six proposed creative thinking tools was developed and administered to a group of 3rd Year Mechanical Engineering Undergraduates in the studied university. The Torrance Test of Creative Thinking Figural Forms were applied to measure the creativity level of respondents in this research. The effects of the Creative Thinking Skills Module developed is obtained through Pre-Test and Post-Test research method, Paired Sample T-Test and Wilcoxon Signed-Rank test are used to analyse the scores, and results indicated the module developed has significantly improved the creativity of the undergraduates.
