Abstract

In the 2025/2026 academic year, the Minister of Education, Culture, Research, and Technology (Permendikbudristek) planned to reinstate majors in high schools. This policy quickly sparked public debate, generating a variety of responses from the public, particularly on YouTube. This study was conducted to analyze public sentiment towards this policy using the Random Forest algorithm. Data was obtained through YouTube comment collection between April 2025 and June 2025, which yielded 4,181 comments. The analysis showed that YouTube comments on videos regarding the policy of reinstating majors in the high school curriculum had a more positive response than negative, with a ratio of 18.3% compared to 5%, with a total of 76.7% neutral. The model's performance in classifying sentiment achieved an overall accuracy of 83.16%, with a precision of 77.56%, indicating a fairly reliable model prediction. However, recall was at 57.25%, indicating that the model still had difficulty detecting all data in small classes such as positive and negative. Overall, the model's performance is represented by an F1-score of 61.26%. This research is expected to serve as a consideration for education leaders or the Minister of Education, Culture, Research, and Technology in determining whether a policy needs to be enacted or changed.

Abstract

Room reservation management at Universitas Negeri Jakarta's Dewi Sartika Building faced persistent inefficiencies in the existing SIPERAD (Sistem Informasi Peminjaman Ruangan dan Presensi Perkuliahan) platform, including manual one-by-one data entry, the absence of a data export feature, and uncertainty about whether scheduled classes were actually held, which caused rooms to remain marked as occupied although they were in fact vacant. This study aims to develop and implement a web-based room management system with an integrated automatic notification feature to confirm classroom usage and improve room utilization efficiency. The system was developed using the Waterfall method, covering requirements analysis, system design with UML and Entity Relationship Diagram modeling, backend and frontend implementation using the Laravel framework, and system testing. The developed features include automatic web push notifications sent one day before scheduled classes, a course-in-charge confirmation mechanism, bulk data import via CSV, and report export in Excel and PDF formats. Testing was carried out using Black Box Testing to verify functional requirements and User Acceptance Testing (UAT) to assess user acceptance. Black Box Testing results showed that all 31 test scenarios for the Admin role and all 5 test scenarios for the Student role produced valid outputs, indicating 100% functional validity. UAT results indicated a very high acceptance level, with satisfaction percentages of 95.79% from Admin users and 89.69% from Student users, both categorized as "Very Good". These results demonstrate that the developed system successfully addresses the identified limitations of the existing SIPERAD platform and effectively supports real-time, transparent, and efficient room management at Universitas Negeri Jakarta.
