Alhamdulillah. Thank you to ALLAH SWT for giving me a chance to complete my thesis. Also for giving me strength and blessing in this ongoing life.
I would like to express my appreciation to my supervisor, who patiently motivates me, Associate Prof Dr. Mohd Bakri Ishak, for his guidance, advice, invaluable suggestion and support for completing my project successfully.
Besides, I really thankful to my colleagues in Faculty of Environmental Studies, UPM, for moral and physical supports. Also special thanks extend to Rosie Jotin and Khairiyah Abdul Rahim for their continuous support and stimulation. To KSM, thank you for your soul therapy.
My deepest appreciation to my beloved parents, Ahmad Rusli Mohd Sedik and Siti Zaiton Sayuti, also my siblings for their interest, encouragement, and support during my studies.
To all that unmentioned above, you know who you are, and thank you very much. May ALLAH SWT bless us all.
