Abstract

The research findings indicate that investigator competence has a significant influence on the performance of the Criminal Investigation Unit members of Tanah Laut Police Precinct. The multiple linear regression test results show that investigator competence (X1) has a regression coefficient of 1.525 with a significance value of 0.000 (< 0.05). The partial t-test results also confirm that investigator competence significantly affects the performance of unit members. Similarly, trust in leadership also has a significant influence on the performance of the Criminal Investigation Unit members of Tanah Laut Police Precinct. The multiple linear regression test results indicate that trust in leadership (X2) has a regression coefficient of 0.551 with a significance value of 0.000 (< 0.05). The partial t-test results further confirm that trust in leadership significantly affects the performance of unit members. Investigator competence and trust in leadership jointly have a significant influence on investigator performance. The multiple linear regression test results show that investigator competence (X1) has a regression coefficient of 1.525, and trust in leadership (X2) has a regression coefficient of 0.551, with a significance value of 0.000 (< 0.05), indicating that both variables simultaneously enhance investigator performance.The coefficient of determination (Adjusted R Square) test result of 0.856 indicates that 85.6% of the variation in investigator performance can be explained by investigator competence and trust in leadership, while the remaining 14.4% is influenced by other factors. The R-value of 0.927 demonstrates that the relationship between the two independent variables and investigator performance is very strong.

Abstract

This research specifically applies two classification algorithms—K-Nearest Neighbors (K-NN) and Naïve Bayes—to assess and predict social disturbances. The empirical findings indicate that, in the context of social factors, the Naïve Bayes algorithm achieved a classification accuracy of 93.91%, surpassing K-NN's 73.33%. These results suggest a significant likelihood of social disturbances during the 2025–2026 period. Such disturbances, often involving the Police Brimob Corps, are predominantly driven by social tensions, including intergroup conflict, economic grievances, dissatisfaction with governance, and identity-based strife.The prevalence of socially-rooted unrest underscores the need for multifaceted intervention strategies. As a specialized unit within Indonesia’s national security apparatus, the Brimob Corps is positioned to mitigate these threats through integrated approaches ranging from mass security and enforcement operations to intelligence-led dialogue and preventive engagement. This highlights the vital role of predictive analytics in shaping proactive and adaptive security policies.

An employee will be motivated at work, if the employee is in a pleasant work environment and gets fair   number of maintenance factors is insufficient, it will cause job dissatisfaction. So the maintenance factor does not create job satisfaction but can prevent job dissatisfaction. This research was conducted by survey to a population of 376 Polri members in the Riau Islands Regional Police. Research with quantitative data processing and results show that there is an influence of disciplinary action to performance (89.72%), internal control to performance (8.88%) and workload to performance (4.6%).

Abstract

In the Indonesian context, the application of predictive technology in the police sector still faces various challenges. Some of them are low accuracy, in-date, and difficulty accessing data that results in government bureaucratic inefficiency. Bandar Lampung City is one of the regions in Indonesia with a high crime rate. Data from the Bandar Lampung Police shows that theft cases dominate crime reports in the area. In this study, the improvement of ML model performance is expected to provide more accurate predictions and support police officers in designing more appropriate strategies to tackle theft crimes This study uses two popular Machine Learning (ML) models, namely K-Nearest Neighbors (k-NN) and Naïve Bayes (NB), to analyze and predict theft crimes in the jurisdiction of the Bandar Lampung Police. The approach is carried out using a quantitative method of algorithm k-Nearest Neighbor and Naive Bayes using the Rapidminer application by utilizing 1671 data from the Bandar Lampung Police police report and a survey method with questionnaires. The data collection technique is carried out validly and reliably, then the police report data will be used for prediction and the questionnaire data will be used to support the validity of the prediction. Based on the results of comparative research conducted using the K-NN model and the Naive Bayes model, it is known that the k-NN model on theft victim data based on the type of theft that occurred is able to predict by 98.80% and for the Naive Bayes model is able to predict by 99.85%. And for suspect data in the k-NN model, it is predicted to be 70.00% while the Naive Bayes model predicts 88.00%. In predicting theft incidents in Bandar Lampung, the selection of the Naive Bayes (NB) model proved to be much more effective and had a very high accuracy compared to K-Nearest Neighbors (K-NN). Based on the test results, the Naive Bayes model provides a prediction accuracy of 99.85%, which is much better compared to K-NN which may not achieve the same level of accuracy.

Abstract

The rapid development of information technology has significantly transformed how university students manage their personal documents—from physical to digital formats. Despite this shift, many students still face challenges in managing digital documents systematically and securely. This study aims to examine students’ perceptions of the importance of personal digital document management in supporting academic and administrative activities. The research is grounded in digital literacy theory, the Theory of Planned Behavior, and document management principles as outlined in ISO 15489 and the Indonesian National Archives Regulation No. 26 of 2011. A descriptive quantitative method was employed, utilizing an online survey distributed to 32 active university students across Indonesia. The findings reveal that although the majority of respondents recognize the importance of digital document management, many lack the technical competencies necessary for effective implementation—such as structured file organization, consistent file naming, data backup, and information security. The study concludes that while students' attitudes are generally positive, their limited digital skills hinder consistent and reliable document management practices. Therefore, enhancing students’ digital literacy is essential to ensure efficient, secure, and accountable personal document management.

Abstract

This research analyze public perceptions of Archives majors in higher education through a qualitative approach with a content analysis method. Data were obtained from the responses of ten Quora platform user accounts related to views on job prospects, specialization, and relevance of the Archiving major. The results showed that public perception of this major tends to be neutral to positive. The parameters “tone” and “competent” obtained the highest mean scores, each at 2.3, reflecting that the majority of responses were delivered in a supportive manner and by competent parties. However, the parameters “narrative” and “image” remained at an average score of 2, indicating that the public perception of the Archives major is not yet fully strong. The results show that the archives major should be seen as a relevant and strategic field in the digital age. These results underscore the importance of effective communication strategies, improved information literacy, and collaboration between students, professionals, and educational institutions.
