Abstract

Introduction: Acts of criminal behaviour that occur have various modes and motives. Also, criminals always try to hide or eliminate evidence at the crime scene. In most cases, police or forensic experts often find DNA on items at the crime scene. One of these items is a ring, which is an item that humans often wear. Methods: This study used 24 samples of rings that had been worn for 8 hours and were incubated at room temperature. All these 24 samples then were distinguished into 4 groups, in which each group was consisting of 6 samples and incubated for 0, 1, 3, and 7-days. DNA identification was then carried out using UV spectrometer for DNA quantification and DNAzol method for DNA extraction. Results: The mean result of DNA quantification on day 0 (control) was 1020,833 ± 0.28903 ng/μL, day 1 was 546 ± 0.093569 ng/μL, day 3 was 1066.333 ± 0.117372 ng/μL, and day 7 was 1054.083 ± 0.070733 ng/μL. PCR process used STR primers with loci vWA, FGA, and TH01 and visualization used the silver nitrate method. Conclusion: The final results showed that all samples could be amplified using 3 STR loci, namely vWA, FGA, and TH01.
