d. Abstract
Written briefly in English in one paragraph of 150-400 words, containing background, research objectives, methodology, results and discussion, the conclusion of the study, and your research contributions to science.
e. Keywords
Written in English 1-5 words or groups of words, written alphabetically.
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.
g. Method
Make sure that work can be repeated according to the details provided. It contains technical information of the study presented clearly. Therefore, readers can conduct research based on the techniques presented. Materials and equipment specifications are necessary. Approaches or procedures of study together with the data analysis method must be presented.
h. Results and Discussion
Well-prepared tables and or figures must be the 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The conclusion should be withdrawn based on research findings, formulated concerns, and research purposes.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.
k. Bibliography
Manuscripts are written by using standard citation applications (Mendeley/Endnote/Zotero). APA 6 th (American Psychological Association) reference style is required. Citing an article written by two authors, both authors should be mentioned, however, for three and more authors only the first author is mentioned followed by et al., for example, Rahayu & Sudarsono (2015), Subekti et al. (2014). A series of references should be presented in ascending date order (Retnoningsih et al., 2005; Indriyanti et al., 2007; Rahayuningsih, 2010). Different publications with the same author(s) and year will be presented separately, as follows 2013a, 2013b. References of unpublished data and personal communication should not appear in the list but should be cited in the text only (e.g., Rifai MA 2015, pers. com. (personal communication); Indriyanti DR 2014, unpublished data). In the reference list, the references should be listed in alphabetical order. More or less 80% of references for literature reviews should be the recent (up to date) journals published in the last 10 years, but the rest of 20 % of references can be cited from research reports and or articles.
