ABSTRACT

This study was aimed to develop an environmental-friendly fingerprint visualization using turmeric herb. The turmeric powder size was in the range of 60-200 mesh. The dusting method was done by applying turmeric powder to glass surface, aluminum foil, transparent plastic, plastic cups and compact disk (CD) surfaces that have sebum content from fingerprint samples. This study was also compared with the small particle reagent (SPR) of ninhydrin. The SPR method was done by spraying ninhydrin solution on A4 white paper and doorslag paper. The results of this study indicated that form of fingerprint obtained has the following pattern: radial loop (16.6 %), ulnar loop (63.3 %), tented arch (1.6 %), twinted loop (1.6 %) and plain whorl (16.6 %). The results showed that the turmeric powder dusting method gave a low contrast with yellow colour while ninhydrin SPR provides high contrast with Ruhemann’s purple.
