Abstract

The importance of respecting differences in Riau society is crucial to create harmony and peace. The people of Riau, which are rich in culture, ethnicity, and religion, need an attitude of mutual respect so that harmony is maintained. By respecting differences, we can build good communication between individuals, reduce conflicts, and increase cooperation in various aspects of life. In addition, appreciation for differences can also enrich our experiences and insights, thereby encouraging innovation and creativity in society. This study aims to explore in depth how respecting differences can affect social stability and harmony in society. The type of research used is a qualitative approach. The data collection technique in this study uses interviews, observations, and documentation studies. Data analysis was carried out through thematic analysis and narrative analysis. The results of the analysis show that through education and open dialogue, the people of Riau can better understand the values of tolerance and mutual respect, which in turn will strengthen the unity and unity of the nation. Thus, respecting differences is not only a choice, but also a necessity to create a harmonious and prosperous society

Abstract

Shigella flexneri can cause shigellosis, which results in high fever, vomiting, diarrhea, or death. This study developed a detection method based on real-time polymerase chain reaction that targets the sfmD gene of S. flexneri given that the virulence factor encoded by this gene is thought to facilitate adhesion to a host surface. The proposed method involves primer design, DNA isolation, the optimization of primer annealing temperature, and confirmation, specificity, and sensitivity tests. A sfmD primer with an amplicon length of 155 bp was annealed to the target DNA at an optimized temperature of 60 ℃ (range 54 °C–62 °C). This primer pair amplified the target sequences at a cycle threshold (Ct) of 15.11 ± 0.38 and a melting temperature of 82.41 ± 0.01 ℃. The primer specificity test showed that the primer distinguished S. flexneri from nontarget bacteria. The findings also revealed that the primer detected S. flexneri down to a limit of 16 pg/μL at a Ct of 26.68, equivalent to 2.79×102 CFU. Overall, the sfmD primer can effectively amplify S. flexneri DNA. Future research can be directed toward the detection of S. flexneri in artificially contaminated food samples to validate the real-food applicability and strengthen its potential use in food safety monitoring and clinical diagnostics.
