The Master’s Program in Linguistics at Universitas Gadjah Mada, through the Forensic Linguistics course taught by Dr. Sailal Arimi, M.Hum., in collaboration with the Criminal Investigation Unit (Sat Reskrim) of the Malinau Regional Police under the North Kalimantan Regional Police, organized a special technical lecture entitled Writing Expert Witness Examination Reports. The event was held on Thursday, 30 April 2026, in Courtroom 1 of the Faculty of Cultural Sciences at Universitas Gadjah Mada, Yogyakarta.
In addition to being attended by the course instructor, who also serves as a language expert, the event was joined by students with an interest in Forensic Linguistics. Student participation aimed to introduce linguistic perspectives into the processes and practices of preparing expert witness statements, including understanding the chronology of legal cases, identifying legal subjects, analyzing language-related criminal complaints, and examining the precision of diction, narrative structure, and ambiguity avoidance in official examination reports (Berita Acara Pemeriksaan or BAP).
The event featured police investigators AIPDA Budi Hermansyah, S.H., and Bripda Abimanyu Akbar, S.H., from the Criminal Investigation Unit of the Malinau Regional Police, along with several graduate students in Linguistics. In their presentation, the investigators explained the distinction between preliminary inquiry (penyelidikan) and formal investigation (penyidikan). They emphasized that expert witness testimony constitutes one form of legal evidence (novum) necessary for bringing a case before the court. They also discussed recent developments in the implementation of Indonesia’s new Criminal Code (KUHP), particularly regarding the expansion of admissible legal evidence. Furthermore, they elaborated on cases commonly handled by investigators, ranging from violations of the Electronic Information and Transactions Law (UU ITE) to various forms of fraud, including phishing, scamming, and related cybercrimes.
Dr. Sailal Arimi, M.Hum., explained that “the involvement of students specializing in Forensic Linguistics in this activity represents part of the implementation of teaching alongside research, as well as an effort to strengthen the role of linguistics within the legal domain.” He further noted that this practitioner-based class has been conducted since 2019 for master’s and doctoral students enrolled in forensic linguistics courses.
During the question-and-answer session, students raised various inquiries concerning legal case management procedures, the eligibility of expert witnesses, and the types of cases most frequently encountered. One student participant, Moh. Nawalul Fawaid El Haqi, remarked that “this experience was extremely valuable. We learned that the meaning of a single word in an expert witness examination report can influence the direction of a judge’s decision. At the same time, investigators also learned to view expert testimony as a text that must be constructed on the basis of theoretical linguistic knowledge that we have studied thus far.”
The collaboration between the Master’s Program in Linguistics, Faculty of Cultural Sciences, Universitas Gadjah Mada, and the Criminal Investigation Unit of the Malinau Regional Police represents a pioneering initiative in bridging police science and forensic linguistic analysis. This activity is expected to serve as a collaborative model for handling legal cases across regions—particularly between Kalimantan and Java—while enhancing the quality of investigations through an interdisciplinary approach at the national level.
