Abstract

The escalation of geopolitical conflict between Iran, the United States, and Israel in 2026 triggered fluctuations in global oil prices, subsequently driving up domestic fuel prices in Indonesia and provoking various public responses on social media. This study aims to analyze the dynamics of public sentiment toward this issue and examine its temporal relationship with fuel price movements. The research data comprises 3,000 YouTube comments collected during the January–June 2026 period, classified using the IndoBERT model (indobenchmark/indobert-base-p1) fine-tuned with a Stratified 5-Fold Cross Validation scheme, Class Weighting, and Focal Loss to address class imbalance. A total of 900 comments were manually labeled as training data, while the remaining 2,069 comments were predicted by the model, resulting in 2,967 fully labeled data points. Weekly sentiment dynamics (n=24) were analyzed using four trend-testing methods (Linear Regression, Mann-Kendall, Spearman Correlation, and Chi-Square/Cramer's V), while the sentiment–fuel price relationship was tested using three approaches (Level Linear Regression, Cross-Correlation Function, and Differenced Regression). Results show the model achieved an average Macro F1-score of 0.7476 (SD=0.0297) with stable performance across folds. Sentiment distribution was dominated by the Negative class (57.1%), followed by Neutral (23.2%) and Positive (19.7%). Trend testing indicated a gradually improving sentiment trend, confirmed by three of four methods, while the relationship analysis found strong lag-3 correlations for three of five fuel types that did not persist under differenced regression, suggesting a possible spurious correlation rather than a confirmed causal relationship.

Abstract

This study empirically examines the determinants of auditor performance in audit firms located in Jakarta, focusing on the distinct impacts of mentoring, audit automation, and work autonomy. Utilizing a quantitative explanatory design, primary data were gathered through a structured questionnaire administered to 78 eligible auditors with at least two years of professional auditing experience. Multiple linear regression analysis was performed to evaluate the hypothesized relationships. The empirical findings indicate that mentoring and audit automation exert positive and statistically significant effects on auditor performance, underscoring the critical roles of experience-based knowledge transfer and technological integration in enhancing audit execution. Conversely, work autonomy demonstrates a statistically significant negative effect on performance, suggesting that excessive discretion without corresponding supervisory controls and clear procedural boundaries may induce role ambiguity and impair engagement quality. These results highlight the need for audit firms to strategically align automated technologies and structured mentorship initiatives with adequate supervisory oversight to optimize professional performance.

Abstract

Visitor logbook recording at the State Administrative High Court (PTTUN) of Palembang has traditionally relied on a physical guestbook, which creates several problems such as difficulty in retrieving past records, the risk of data loss or damage, illegible handwriting, and the absence of automatic data recapitulation for reporting and security-monitoring purposes. This study aims to design and build a web-based Digital Guestbook Information System using the Prototype development method, integrating self-service visitor data entry, entry and exit verification by security officers, and visit monitoring and reporting by administrators and management within a single, unified platform. The system design is modeled using a Use Case Diagram, Activity Diagram, Class Diagram, and Entity Relationship Diagram (ERD), then implemented using the PHP Native, and a MySQL database. The results show that the developed system speeds up guest registration without a physical logbook, automatically generates queue numbers, facilitates exit-time confirmation by security officers, and provides statistical dashboards and visit reports that can be filtered and exported to PDF.

Abstract

This study aims to compare the results of cut and fill volume calculations using the Grid and Cross Section methods against the Triangulated Irregular Network (TIN) method as a reference, based on topographic data processed using AutoCAD Civil 3D. The study employed a descriptive quantitative approach using coordinate and elevation data obtained from topographic measurements. Data processing was conducted using AutoCAD Civil 3D 2026, with a 10 × 10 m grid size applied in the Grid method. The results were compared using the Root Mean Square Error (RMSE) and percentage difference in volume. The TIN method produced a cut volume of 12,484.50 m³ and a fill volume of 25,339.83 m³. The Grid method produced 12,071.49 m³ of cut and 24,786.27 m³ of fill, while the Cross Section method produced 11,789.62 m³ of cut and 24,413.91 m³ of fill. Based on the RMSE and percentage difference, the Grid method produced results closer to TIN than the Cross Section method.
