Abstract
This research aimed to develop dust for the detection of latent fingerprints using carbon powder produced from the pyrolysis of tires and to compare the detection of latent fingerprints between the developed dust and the standard powder imported from the United States and Japan. This study was done through experimental research by evaluating the results from the detection of latent fingerprints on five types of smooth and non-porous surfaces (glass, a plastic cup, a plastic file, the back of a CD, and a soft drink can) and the latent fingerprints were analyzed for a number of special features with AFIS. The results showed that the carbon dust from tires had a particle size of 45.9 ± 3.49 µm, which was close to the commercially available powder particles imported from Japan (particle size of 39.5 ± 0.56 µm). In addition, the clarity of latent fingerprints generated from tire carbon powder on five types of surfaces, were plastic cup surface > soft drink can > the plastic file > drinking glass > and the back of a CD, respectively.
