ABSTRACT DNA barcoding is a molecular technique used to identify organism in the form of short DNA sequences. One of the chloroplast markers (cpDNA) that are widely used as a molecular marker is a trnL-trnL-trnF intergenic spacer which is part of the DNA genome that is non-coding. This study aims to analyze the trnL-trnL-trnF intergenic spacer barcode sequence on small jengkol fruit plants (Ar…
