INTRODUCTION

The introduction is written with 1.5 spacing in Times New Roman 12 pt font. It contains the background, discussion of the problem to be described, relevant literature review, objectives, and significance of the research. The literature review consists of the most recent articles related to the topic discussed, published within the last five years. Literature published over a longer period of time may be used as long as it is still relevant, and the amount should not exceed 50% of the total literature. References must be publications from the last 10 years, with a minimum of 80% journals and 20% textbooks. For writing the article content, this template should be used to facilitate the author in arranging the layout of the article written. The editor-in-chief will check the conformity of the article content with the prepared article template, so it is expected that the article follows these writing rules as best as possible so that when printed as a journal, it will be uniform for each article written. Writing references in the text follows APA style format. Citing quotations, such as "Aswarina (2023) in Khairiza et al., (2022)", and using 'Anonymous' as a reference is not allowed. Examples of writing the author's name when citation at the beginning or end of the sentence such as the name of a single author in Citation: Mustaqim (2023) states that… or… has an effect on different conditions (Agung, 2022). The names of two authors in Citation: Shafwan and Mustaqim (2024) state that… or… in optimal conditions (Gilang and Mustaqim, 2023). The names of three authors in Citation: Mustaqim et al. (2022) state that or improves the quality of chicken meat (Chairunas et al., 2022).

 

RESEARCH METHODS

Materials and Methods are written with 1.5 spacing in 12-point Times New Roman font. They clearly cover the location and time, experimental plan, implementation method, and data analysis. Materials and Methods can be divided into sub-chapters to facilitate reader understanding of the manuscript. Methods that are generally known or have been published only need to include the source or reference. For special (modified) or new processing and analysis methods, the working procedures are listed in detail. Sub-headings can be adjusted to suit the methods used in each study.

 

RESULTS AND DISCUSSION

The results are written with 1.5 spacing and 12-point Times New Roman font. The data are presented concisely and concisely, explaining only significant findings relevant to the discussion presented based on the method used. If you wish to refer to a table/graph/diagram, or image, the results in that section can be explained clearly without using the phrase 'See Table 1/Figure 1'. If using the average value, the standard deviation must also be included. The discussion should be written with 1.5 spacing in 12-point Times New Roman font. The discussion should not be a summary of the results. It should explain the reasons for the results and their significance. If possible, the results of this study should be compared with previous research. The discussion should be consistent and should interpret the results clearly and concisely, addressing the biological mechanisms and their significance, supported by appropriate literature. The discussion should demonstrate the relevance of the results to the field of inquiry.

 

CONCLUSION

The conclusion should be written briefly in one paragraph, but reflect the experimental results obtained, with a maximum of 100 words and the font used is Times New Roman 12 pt. Suggestions may be added if necessary.

 

ACKNOWLEDGMENT

Thank you (if any) to the people or institutions who assisted with the research. The font used is Times New Roman 12 pt.

 

REFERENCES

The bibliography is located at the end of the article and is arranged alphabetically by the main author's last name. A minimum of 25 references should be cited. The font used is Times New Roman 12 pt, with 10 mm hanging format, as in the example below. Text or sentences within the main idea that refer to the references should be marked with the author's last name.
