METHOD This research was conducted using a qualitative approach because it aligns with the definition of a qualitative approach above. Qualitative research methodologies are the specified philosophical and theoretical frameworks applied in a systematic inquiry into social phenomena in a natural setting (Creswell & Poth, 2018, as cited in Urcia, 2. The research conducted is closely related to society, which is dynamic and poured into descriptive data that can be observed and specific, which means it is by facts in the field (Prasetyo et al. , 2022. Alifuddin et al. , 2021. Siregar et al. , 2. This type of research is a case study and field research related to problems in the subject and object of research (Hancock et al. , 2021. Schwartz, 2.

People who come to report a crime to the SPKT, do not immediately make a Police Report by This lack of support can discourage individuals from pursuing immediate documentation of their reports (Mbewu et al. , 2021. Xie et al. , 2019. Only reports that have fulfilled two sufficient pieces of evidence will be made a Police Report by officers.
