Start from vol 7 (2019), plagiarism screening will be conducted by the editors of Journal of Indonesian Natural History (JINH) using similarity software (Turnitin). Article manuscripts must obtain a similarity index of less than 30%. We will return the manuscripts to authors should the similarity index is more than 30%. Authors may rewrite the manuscripts to meet our requirement in this regard and resubmit the rewritten manuscripts. The resubmitted manuscripts will go into the new screening process, and if for any reasons the similarity index is still above 30%, the editors will reject the manuscripts.
