Abstract

Identification processes are not only conducted on the dead body of criminal victims, but also on the evidences founded at the location. The length time between crimes happened and investigation of the evidences is the problem in blood groups identification process through saliva traces on cigarette butts. Wet saliva usually becomes traces in an hour and 40 minutes at room temperature and up to less than 3 hours if there any influenced factors. The purpose of this research is to analyze the effects of heat exposure duration on protein content of the saliva traces on cigarette butts in order to help forensic blood group identification process. Time series design was used in this research which 18 cigarette butts was collected from 6 individuals of blood group A, B, and AB. The samples were then incubated for 1.3 and 6 hours. Protein content was determined using trizol reagent and Spectrophotometer UV. Statistical analysis using T-test was conduct to analyze the results. There was a decrease in protein content of the saliva traces samples at the time points 1, 3, and 6 hours. Protein content of the saliva still can be detected at the time points 1, 3, and 6 hours. These finding suggest that protein analysis of saliva traces samples on cigarette butts can be used in forensic blood group identification process.
