Thank god for his presence, who has granted me his grace and his father so that I may finish this task thank you I thank my beloved lecturer who helped us to complete this task. Also, I thank my comrades in arms who have supported me so that I can complete this task in time. I realized that my assignment was far from perfect either the drafting, the language, or the writing. Therefore, I strongly expect constructive criticism and advice from all readers to be a model for me to be better in the future. It is hoped that this assignment will broaden the minds of readers and can be useful to the growth and uplift of science.
