Latent Fingerprints is forensically important evidence because it’s always used in identification method that highly accurate. This method is convenience because less complicate and rather safe. In crime scene, latent Fingerprints may be found on many surfaces such as glasses, paper, tile and human skin. In this research, aim to study the visualization of latent Fingerprints on human skin by black fingerprint powder and powder mix between fluorescence powder and black fingerprint powder. The experiment, latent Fingerprints was collected from 25 female’s skin surfaces at immediately and 30 minutes later and then they were detected minutiae points by fingerprint professional. The result was show that detection by black fingerprint powder and powder mix between fluorescence powder and black fingerprint powder are not different level of 0.05 statistically significant and 30 minutes collecting cannot detected fingerprints.
