Abstract
Written in two languages (Indonesian and English) of no more than 250 words. The abstract is the essence of the entire paper which includes the problem, objectives, materials and methods, results and discussion, and research conclusions. In the abstract, as in the main text, every common name of an organism or trade name of a chemical must be followed by its scientific name, at least at the first mention. The abstract is completed with keywords, a minimum of three words, arranged from general to specific.

Keywords: Keywords include a maximum of six words, with the first word being the most important and relevant to the topic. The writing of keywords is separated by semicolons (;), font size 10pt.

Introduction
This is the background of the research consisting of the problem or hypothesis that prompted the research, the findings to be refuted or developed, and the purpose of the research. The introduction must be written in size 12 pt, bold, left-aligned, capitalized. The literature review should be a recent article on the topic, published within the last five years. Literature writing in the text follows APA style format.

Materials and Methods
Clearly describe the place and time, research material, experimental design, method of implementation, and data analysis method. Writing Materials and Methods using size 12 pt, bold, left-aligned, capital letters. Materials and methods can be sub-chaptered to make it easier for readers to understand the manuscript. Writing sub-chapter titles with bold capital letters at the beginning of the sentence.

Results
Results: the discussion must be written in size 12 pt, bold, left-aligned, capital letters. Research results are clearly stated, if necessary accompanied by tables, illustrations (graphs, diagrams, drawings), and photographs. Information that has been explained with tables and illustrations does not need to be repeated with lengthy descriptions in the text. The discussion contains an analysis of the research results, how the research can solve problems, differences or similarities with previous research, and possible developments.

Discussion
Discussion: the discussion must be written in size 12 pt, bold, left-aligned, capital letters. The discussion is not a repetition of the results. The discussion reveals the reasons for obtaining the results and the meaning or significance of the results obtained. If possible, the results of this study can be compared with previous studies. Present the research results first before including the opinions of other relevant researchers. The writing of the Results and Discussion can be sorted into sub-subchapters, according to the aspects studied. In the writing, the Results chapter is separated from the Discussion chapter.

Conclusion
Contains important things from the research results and discussion, in accordance with the title and research objectives and is presented concisely in the form of a narrative, not a pointer. Research results written in the conclusion do not need to be discussed.

Acknowledgments
The author should give appreciation to those who have helped conduct the research or other parties who contributed to the research. Appreciation is given in the form of acknowledgments.

References/citations
Using the name-year system, limited to things that are closely related to the research. Citations for tables and illustrations are listed as sources and included in the last line.

Bibliography
The writing of the bibliography uses size 12 pt, bold, left-aligned, capital letters. The bibliography is displayed at the end of the article and is sorted alphabetically from the last name of the main author. The font used is Times New Roman 10 pt, with 8 mm hanging format, as in the example below. The text or sentence in the main idea that refers to the reference is marked with the last name of the author. Citations and references are written in APA Style. We recommend that authors use a reference management system (RMS) such as Mendeley, Zotero, or Endnote.
Bibliography is organized alphabetically by the first author's (family) name. Bibliography in the text or narrative uses the "name-year" system in two forms, e.g. Dobermann & Fairhust (2000) in the middle of a sentence or (Dobermann & Fairhust 2000) at the end of a sentence.
If more than one reference is mentioned together then the writing is organized by year of publication. Example: (Harahap & Panjaitan 2003; Suparyono 2005; Sumarno & Suyamto 2007; Muliari et al., 2012). If there are more than two authors, the name (family) of the first author is followed by et al. However, et al. is not used in the bibliography. All author and editor names are written in full in the bibliography. The use of "anonymous" references is not allowed. Any literature referenced in the text, tables or illustrations must be included in the Bibliography, and vice versa. At least 80% of the references should be from new primary scientific journals published within the last 10 years.

Table
A short and clear title, followed by a description of the place and time of data collection. Columns/children of columns are clearly separated. The ditto sign (") is not used. The number of decimals is as simple as possible. Table footnotes are marked with small superior letters (slightly raised) to distinguish them from text footnotes with numbers.

Illustrations are made with clarity, contrast, neatness, cleanliness, and can be corrected by the editor for publishing purposes. Illustration files can be included separately with the manuscript to facilitate corrections by the editor.
