Abstract

Death registration is very important and has civil and legal impact on the deceased person and their family. Validity of a death certificate is influenced by the time accuracy of death estimation. Calculation of the post-mortem interval has a central role in the estimation of the time of death, especially for death cases in the community, without prior medical observation. This study aimed to develop a smartphone application for counting the estimated time of death based on android features, to help doctors establish a more accurate time of death and provide a learning facility for doctors and medical student. This action research consisted of 4 cycles: 1) Planning, 2) Action, 3) Observation, and 4) Reflection. The final result of this study is an android application named Forensica 3rd version. This application was developed in Bahasa Indonesia. This application has a menu for recording the patient identity, instructions for post-mortem changes examination, record examination results, time of death calculation and its interpretation. This 3rd version of the application is the latest version after undergoing two revisions. The Forensica application provides an easy way for doctors and medical students to establish the time of death estimation and it is user-friendly.

Abstract

Wounds result from physical violence that damages the continuity of body tissues and are frequently observed in forensic medicine and medicolegal science. In forensic medicine and medicolegal science, wounds play a significant role in creating a medicolegal examination and report (VeR) for deceased individuals and living victims. However, research findings indicate that the quality of clinical forensic descriptive results in VeR needs to improve in several hospitals in Indonesia. Meanwhile, high-quality VeR results are crucial in determining penalties for perpetrators in court, and poor VeR results can hinder the legal process. The application of information technology in medicine has yielded numerous tools that can assist experts in carrying out their duties. Likewise, clinical forensics, a generally conservative forensic pathology practice, can be enhanced through image-processing techniques and machine learning. Digital technology support for forensic cases has been available previously, such as in forensic photography; however, its application still needs improvement, and further development is required. This study applied a Yolo V4-based machine learning and image processing algorithm to classify and detect types of wounds. This algorithm was chosen for its high speed and accuracy in classification and detection tasks. The research results showed that the learning model's performance, measured in accuracy, precision, recall, and average F1 score, reached 92%. Usability testing showed that the system performed well and could be helpful with minor improvements.

Abstract

Perundungan atau bullying masih sering terjadi dalam kalangan anak-anak hingga remaja dengan angka kejadian yang masih mengkhawatirkan dan berdampak negatif pada perkembangan anak. Studi ini bersifat evaluatif dengan desain pretest posttest dalam satu grup untuk melihat apakah penyuluhan dapat menjadi metode diseminasi yang efektif untuk kesadaran akan bullying. Penyuluhan dilakukan kepada 18 orang remaja di Karang Taruna Kapanewon Cangkringan, Sleman, Yogyakarta, dengan tujuan untuk memberikan pengetahuan dalam deteksi dini, pencegahan, dan tata cara pelaporan kasus bullying secara aman. Pretest dan posttest juga dilakukan untuk mengevaluasi pemahaman peserta. Nilai antara pretest dan posttest mengalami peningkatan pada seluruh 18 responden. Pretest memiliki nilai rerata 75,6 (SD 11,99) dengan median 80,0, sedangkan posttest dengan nilai rerata 92,2 (SD 8,78) dengan median 90,0. Hasil analisis bivariat dengan paired t-test menunjukkan adanya perbedaan signifikan antara nilai pretest dan posttest (p <.001). Ditemukan juga hubungan signifikan antara peningkatan nilai pretest-posttest dengan jenis kelamin maupun usia (p <.001). Oleh karena itu, penyuluhan dan pretest-posttest dapat menjadi media yang efektif untuk meningkatkan kesadaran masyarakat terhadap bullying dengan memperhatikan faktor sosiodemografi peserta itu sendiri.
