Abstract

Fingerprinting is a forensic science used in criminal investigations. The method most often used in fingerprints is the dusting method because it is relatively simple and easy. However, some of the chemical substrates used are toxic and potentially harmful to health. To overcome this problem, the development of fingerprints using durian seed powder is easier to obtain and provides a clear print. The results of development using durian seed powder, the size of 100 mesh and 200 mesh on the surface of aluminum foil and glass preparations providing a clear visualization of fingerprint patterns and good color contrast. Meanwhile, the powder sizes of 60 mesh and 80 mesh resulted in poor visualization. The highest percentage of fingerprint patterns formed based on ethnicity was the loop pattern of 21.1% in the Malay ethnic group, 20% for the Batak tribe, and 17.7% for the Batak tribe. The highest percentage of fingerprint patterns formed based on blood group were the loop pattern of blood type O 31.1%, blood group B 12.2%, blood group AB 8.8%, and blood group A 6.6%. The highest percentage of fingerprint patterns that were formed based on gender was the loop pattern 45.5% for women, and 13.3% for men.
