Abstract

The study aims to compare efficiency between Talcum Powder and White Powder that are used to develop latent fingerprints on black non-porous surfaces. The efficiency was compared through an experiment in which latent fingerprints were collected from black non-porous of three different surfaces include tiles, glasses and plastics on five different period after stamped fingerprints to collecting include instant after stamped, 1 day after stamped, 5 days after stamped, 7 days after stamped and 14 days after stamped. Comparison of the efficiency was carried out by counting minutiae from Automated Fingerprint Identification System (AFIS). Then analysed the data with Independent T-Test Statistic to compare efficiency between Talcum Powder and White Powder that used to develop latent fingerprints on black non-porous surface. The results revealed that Talcum Powder was as efficient as White Powder that used to develop latent fingerprints on 3 different black non-porous surfaces and 5 different period after stamped fingerprints to collecting.
