All manuscripts submitted to NusaPlant (Journal of Nusantara Plantation Science) will undergo a similarity check using software such as Turnitin or iThenticate.

The maximum acceptable similarity index is 20%, excluding the reference list and properly cited quotations. Manuscripts exceeding the specified threshold may be returned to the authors for revision or rejected, depending on the extent and nature of the similarity identified.

The similarity report is one of the considerations in the editorial process and does not automatically determine whether plagiarism has occurred. The Editor may conduct further assessment of the identified similarities by examining their sources and context.
