Post-Publication Discussion

HEXAGRO welcomes scholarly discussion of its published articles. Readers may comment on, question, or add to an article through a Letter to the Editor.

Submitting a letter

• Send the letter by email to hexagro@unper.ac.id, with the title and DOI of the article it refers to.
• Letters should be concise, written in English, focused on the scientific content of the article, and supported by references where relevant.
• Letters must be respectful; personal attacks or defamatory content are not accepted.

How letters are handled

1. The Editor-in-Chief assesses whether the letter raises a substantive scholarly point.
2. The authors of the original article are invited to reply.
3. Selected letters and the authors' replies are published together in a following issue and linked to the original article.

If a letter or other source (for example, discussion on platforms such as PubPeer) reveals an error or possible misconduct, the journal acts under its Retraction, Correction, Complaints and Appeals policy and its procedure for Allegations of Research Misconduct.
