Abstract

This study aims to analyze security vulnerabilities and mitigation on the crowdo.co.id website using the OWASP Zed Attack Proxy (ZAP) tool, which is a web application security testing tool. High-level security attacks have increasingly risen alongside the advancement of information technology, making vulnerability testing crucial to ensure the integrity and security of information systems. This research involved scanning the crowdo.co.id website to identify various vulnerabilities, including those listed in the OWASP Top 10. The research process encompassed active and passive scanning, data analysis from the scans, and the formulation of mitigation strategies for each identified vulnerability. The findings revealed that the website had 14 detected vulnerabilities, consisting of 1 high-priority vulnerability, 3 medium-priority vulnerabilities, 7 low-priority vulnerabilities, and 3 additional informational alerts. The security dimensions tested included potential XSS attacks, SQL Injection, and other deficiencies that could jeopardize user data. Based on these results, recommended mitigations include code improvements, enhanced security configurations, and the implementation of additional preventive measures. This study concludes that while the website’s security is in the medium category, further improvements are necessary to reduce vulnerability risks. Through this approach, the study provides significant contributions to enhancing web application security.

Abstract

This study aims to evaluate the service quality of PT TJ Bros using the SERVQUAL method, which includes five dimensions: tangibility, reliability, responsiveness, assurance, and empathy. Data were collected through a Likert-scale questionnaire from 50 active customers selected using purposive sampling. The analysis measured the gap between customer expectations and their perceptions of the company's services.The findings indicate that all service dimensions exhibit negative gaps, meaning the service quality does not fully meet customer expectations. The responsiveness dimension shows the largest gap (-0.80), reflecting delays in responding to customer complaints or requests. The tangibility dimension also demonstrates a gap (-0.40), indicating a need for improvements in physical facilities, such as cleanliness, waiting area comfort, and employee appearance. In the empathy dimension, customers feel a lack of personalized attention, with a gap of -0.60.To enhance customer satisfaction, the company is recommended to improve its customer response system using technology-based complaint management, upgrade physical facilities, and train employees in communication and personalized service. Adjustments to employee uniforms and training to maintain service consistency are also suggested.In conclusion, comprehensive improvements in operational systems, facilities, and employee skills are necessary to enhance service quality. By meeting or exceeding customer expectations, PT TJ Bros can boost customer loyalty and strengthen its competitive position in the market.
