f. Introduction
Explaining the background, problems, importance of research, a brief literature review that relates directly to research or previous findings that need to be developed, and ended with a paragraph of research purposes. A balance must be kept between the pure and applied aspects of the subject. The introduction is presented in the form of paragraphs of approximately 1000 words.

g. Methods

h. Results and Discussion
Well-prepared tables and or figures must be a significant feature of this section because they convey the major observations to readers. Any information provided in tables and figures should no longer be repeated in the text, but the text should focus on the importance of the principal findings of the study. In general, journal papers will contain three-seven figures and tables. The same data can not be presented in the form of tables and figures. The results of the study are discussed to address the problem formulated, objectives, and research hypotheses. It is highly suggested that discussion be focused on the why and how of the research findings can happen and to extend to which the research findings can be applied to other relevant problems.

i. Conclusion
The conclusion should be withdrawn on the basis of research findings, formulated concerns, and research purposes. The conclusion is presented in one paragraph without a numerical form of expression. Explain your research contributions to science.
