I am fortunate to have been surrounded by a wonderful set of people who have profound encouragements. Here I would like to take this opportunity to thank the people who have in no small way made this scientific writing possible. First and foremost, I would like to thank God who always blesses my every small and big step each day and for the intangibles things. Thank you sincerely to my advisor, Mr. Yohanes Hartadi., M.A for exhilarating moments, your benevolence and unwavering enthusiasm in assisting me to finish my scientific writing. All the guidance, extensive knowledge, and excellent advices are always important towards my personal and professional advance.

It also gives me immense pleasure to acknowledge my beloved parents and all of my gorgeous family who always give so much care, support and the unconditional love to me during the tough time. For the most part, truly thanks to my lovely man for all the prudent advices, precious time, wholehearted love without return, big understanding and caring to me. Lastly but not the least, my special appreciation extends to my best friends and all the college’s friends who have offered a shoulder on which to lean, a genuine smile, big support and care shown to me over the years. |
