Abstract

Business to Government (B2G) processes frequently suffer from inefficiencies caused by manual workflows and limited system integration. This study aims to enhance B2G business process performance at PT XYZ by applying the Business Process Improvement (BPI) approach using Business Process Model and Notation (BPMN) implemented through Bizagi Modeler. The research methodology involves analysing the existing process, designing an optimized process model, and conducting performance simulations based on processing time, operational costs, data accuracy, delay risk, and institutional satisfaction. The results indicate significant improvements, including a 41.7% reduction in processing time, a 26.7% decrease in operational costs, a 90% increase in data accuracy, a 40.9% reduction in delay risk, and an 85% improvement in institutional satisfaction. These findings demonstrate that the integration of BPI and BPMN effectively improves the efficiency and quality of B2G business processes in government procurement.

Abstract

The distribution of subsidized fertilizer plays an important role in supporting agricultural productivity; however, its implementation at the regional level still faces mismatches between allocation and actual land requirements. This study aims to determine the priority of subsidized fertilizer distribution for paddy agricultural land in Central Java Province using a scoring method based on Geographic Information Systems (GIS). The variables applied in this study include harvested area, land productivity, and elevation. The data used are secondary data obtained from the Central Statistics Agency (BPS) for the period 2022–2024. The scoring process was conducted using Microsoft Excel with a five-level ordinal scale and equal weighting for each variable. The scoring results were then integrated with spatial analysis using QGIS to produce thematic maps of fertilizer distribution priorities. The results indicate that each regency in Central Java Province has a different priority level, which is classified into low, medium, and high priority categories. Out of 35 regencies/cities analyzed, 17 regions (48.57%) were classified as high priority, 11 regions (31.43%) as medium priority, and 7 regions (20%) as low priority. Validation results show that most high-priority areas also receive relatively large amounts of subsidized fertilizer, although some discrepancies remain due to policy considerations and regional characteristics. This study demonstrates that a GIS-based scoring method can be used as a supporting tool for planning and evaluating subsidized fertilizer distribution in a more objective and spatially informed manner.

Abstract

This study aims to examine the effects of usability quality, information quality, and service interaction quality on user satisfaction with the official website of Muhammadiyah University of Purworejo using the WebQual 4.0 framework, supported by Importance-Performance Analysis (IPA). A descriptive quantitative approach was employed, with data collected through an online questionnaire distributed to 130 active students selected using non-probability convenience sampling; 30 responses were used for validity and reliability testing, while 100 responses were analyzed in the main study. The data were processed using IBM SPSS Statistics 26 through Pearson correlation, Cronbach’s Alpha, multiple linear regression, partial t-tests, coefficient of determination, and IPA. The findings reveal that usability quality has a negative and significant effect on user satisfaction (β = −0.168; p = 0.037), whereas information quality (β = 0.284; p = 0.001) and service interaction quality (β = 0.533; p = 0.000) have positive and significant effects, with service interaction quality emerging as the strongest predictor. The model explains 67.6% of the variance in user satisfaction. The originality of this study lies in its explanation of the negative usability effect through expectation-disconfirmation theory and the Technology Acceptance Model, as well as its integration of WebQual 4.0 regression with IPA to generate prioritized improvement strategies. The findings imply that UMPWR website managers should urgently improve interface usability, maintain strong service interaction quality, and sustain accurate and timely information provision to enhance user satisfaction.

Abstract

Pothole detection based on deep learning has achieved high detection accuracy; however, most existing studies evaluate models using the same dataset for both training and testing, providing limited evidence of robustness under unseen data distributions. This study investigated the cross-dataset generalization capability of YOLOv8n using three publicly available pothole datasets with different visual characteristics: the Multi-Weather Pothole Dataset (MWPD), the Jaygala dataset, and the Andrew dataset. The proposed framework evaluated same-dataset and cross-dataset detection performance, quantified robustness through generalization gap analysis, examined the influence of dataset characteristics, and assessed the effectiveness of multi-dataset pretraining. Experimental results showed that the Andrew dataset achieved the highest same-dataset performance (mAP@50 = 0.816) but also exhibited the largest generalization gap (0.246), indicating limited robustness across datasets. In contrast, multi-dataset pretraining reduced the generalization gap for MWPD from 0.093 to 0.048, demonstrating improved cross-dataset robustness, although the improvement was not consistent across all datasets. These findings indicate that same-dataset accuracy alone is insufficient for evaluating model robustness and that cross-dataset evaluation provides a more realistic assessment of deployment performance in heterogeneous road environments.

Abstract

This research explores the effectiveness of Virtual Try-On (VTO) technology in fostering brand loyalty within the cosmetics industry. Using a mixed methods approach that integrates quantitative surveys, user experiments, in-depth interviews, and social media sentiment analysis, the study examines how interactive digital experiences via VTO influence consumer trust, emotional engagement, and perceived product quality. Findings from 100 survey respondents, 10 user experiments, and 15 interviews indicate that VTO significantly enhances purchase intention and strengthens the emotional bond between consumers and brands. Regression and path analysis results reveal a positive, statistically significant effect of VTO on brand loyalty, with trust and emotional engagement acting as key mediators. Sentiment analysis of 300 user comments further confirms that VTO is widely perceived as intuitive, realistic, and helpful in decision making. These insights highlight VTO’s dual function not only as a tool for visualization but also as a medium for emotionally resonant digital interaction. The study contributes theoretically by expanding brand loyalty discourse through the lens of technological interactivity. Practically, it offers strategic guidance for cosmetic brands to leverage VTO in enhancing user experience, reducing product returns, and boosting engagement. The research underscores the importance of designing VTO features that are visually appealing, emotionally impactful, and adaptive to diverse consumer needs. In a competitive digital marketplace, VTO emerges as a critical differentiator in creating immersive, personalized, and loyalty driven shopping experiences.
