Abstract

Web-based platform security is an important aspect that developers must consider. However, numerous developer still exhibit insufficient attention to enhancing the security level of their websites, thereby increasing the likelihood of these platforms becoming targets of cyber attacks. To address this challenge, the utilization of tools such as Nuclei Vulnerability Scnner and Owasp Zap presents an effective solution for the rapid detection of potential vulnerabilities  in web-based platforms. This research involved testing a locally developed dummy web application , with scanning processes conducted using the Nuclei Vulnerability Scanner and Owasp Zap tools. The findings reveal that Nuclei Vulnerability Scanner proves effective in identifying vulnerabilities at the network layer, particularly in relation to SSL/TLS protocols and proxy configurations. In contrast, Owasp Zap is more focused on detecting vulnerabilities  within the web application layer, especially concerning security header configurations  that may be exploited through browser-based attacks such as XSS and clickjacking. Mitigation of the identified  vulnerabilities resulted in a substantial reduction in their severity, with a 90% decrease in Nuclei and an 80% reduction in Owasp Zap. Both tools demonstrated high accuracy and efficient scanning times, establishing them as effective solutions for enhancing security across both network and application layers. This study recommends the integration of these tools into a comprehensive cyber security strategy  to safeguard system integrity and availability while addressing the continuously  evolving threat landscape, in alignment with the layered security principle advocated in contemporary literature.

Abstract

Politeknik Caltex Riau manages several scholarships whose funding sources can come from the government or private sector. The management of this scholarship scheme is done manually in the form of collecting files and recaps via Ms. Excel. In addition, the scholarship management process is carried out by an operator, namely the Head of Student Affairs, so it takes a long time to carry out the selection process until the announcement of scholarship recipients and has the potential for errors. The errors that occur include duplication of scholarship recipients, miscalculation of the scholarship funds submitted and inconsistency in writing data related to scholarship recipients. In fact, the presentation of information on scholarship recipients is absolutely needed as reporting material to related parties, such as reporting Scholarships to the Riau Provincial Government. Therefore, to assist the operator in managing scholarships, an information system was developed to manage Scholarships at Politeknik  Caltex Riau. In the development of this information system, it was built based on software development standards, namely the Software Development Life Cycle (SDLC) with Waterfall Methodology. The scholarship management system was tested on the head of student affairs, executives and scholarship recipients. From the results of testing this information system, there were no errors and it could run well. In addition, in terms of system acceptance by users, it can be concluded that this system is acceptable and makes it easier to manage scholarships

Abstract

The rapid development of technology has driven almost all business sectors to adopt digital operations, but this shift has also increased the risk of cybercrime, targeting systems and data. Cyber Threat Intelligence (CTI) is a cybersecurity approach that involves collecting, analyzing, and understanding data to identify the motives, targets, and attack patterns of cybercriminals. One solution to address these threats is CrowdSec, an open-source software designed to detect and prevent cyber-attacks in various environments, including servers. Testing results demonstrate that CrowdSec is effective in detecting SSH brute-force, port scanning, and SQL injection attacks. By identifying suspicious attack patterns and blocking attackers' IPs, CrowdSec significantly reduces the risk of server damage. Its response times are fast: 23 seconds for SSH brute-force, 10 seconds for port scanning, and 6 seconds for SQL injection. Compared to Fail2Ban, CrowdSec offers greater configuration flexibility and broader attack detection capabilities, supported by the CrowdSec Hub, which provides a variety of attack scenarios. With its simple installation and configuration process, CrowdSec is an ideal choice for enhancing server security.

Abstract

Preparing a strong portfolio is a crucial aspect for students in entering the workforce, one of which can be achieved through participation in various competitions. However, selecting competitions that align with student competencies remains a challenge due to the abundance of competition information, diversity in student interests and abilities, and limitations in budget, time, and resources. This study develops a recommendation system based on a Hybrid Recommendation System designed to map student competencies to relevant competition types. The system integrates the Naive Bayes method to classify student competencies and Item-Based Collaborative Filtering to calculate similarities between competition types based on other users’ preferences. The system is developed incrementally using the waterfall approach, including the stages of planning, analysis, design, implementation, and testing. The model follows standard machine learning workflows, comprising data collection, exploration and preprocessing, model building, performance evaluation, and method integration. The research data includes student profiles, competencies, and competition preferences collected through surveys and internal databases. Evaluation results indicate that the system successfully provides relevant competition recommendations with an accuracy rate of 70%. These results demonstrate the system’s contribution in assisting students to select competitions that match their competencies, presented in a user-friendly web-based application.

Abstract

Internal training activities at the Information Technology Department of Politeknik Caltex Riau were previously managed in a semi-manual manner without an integrated database, leading to inefficiencies in administrative processes such as identifying potential trainers, participant registration, material documentation, and reporting. These issues resulted in disorganized data management and the risk of losing important information. This study aims to develop a web-based Training Management Information System using the Extreme Programming (XP) method as a solution to improve efficiency and service quality. The development process follows the XP stages: exploration (identifying user needs), planning (scheduling and estimating resources), development iterations (analysis, design, incremental releases, and feedback), and final production (system release and refinement). System evaluation was conducted through usability testing using questionnaires for organizers and lecturers, as well as in-depth interviews with the Head of Department as a strategic user. The results show that 79% of respondents found the system easy to use, relevant to their needs, and functionally adequate. Interviews also confirmed that the system met expectations in terms of features and interface design. These findings indicate that the XP approach is effective in developing user-centered web-based systems and improving the operational efficiency of internal training activities.

Abstract

Heart disease is one of the leading causes of death worldwide, making early detection crucial to prevent more serious complications. One of the methods that can be used is heart sound analysis, which contains important information related to the physiological and pathological conditions of the heart. However, the manual analysis process by healthcare professionals requires specialized skills and may result in interpretation errors. Therefore, this research aims to develop an artificial intelligence-based system using Convolutional Neural Networks (CNN) to automate heart sound classification. This system allows users to upload heart sound recordings, which will then be processed and classified as Normal or Abnormal. The research process consists of several main stages, including data collection and preprocessing of heart sounds, development and training of the CNN model, implementation of the model into a web application, and testing and evaluation of the system using metrics such as accuracy, precision, and recall. The outcome of this research includes a deep learning model for heart sound classification. The developed system is expected to enhance the accuracy and efficiency of heart disease detection, reduce reliance on manual analysis, and serve as an artificial intelligence-based solution that can be integrated into healthcare services.

Abstract

Online gambling in Indonesia is increasingly widespread and has negative impacts, both in terms of socio-economic aspects and cybersecurity. One of the methods used by online gambling operators is inserting gambling backlinks into websites, particularly those with .ac.id and .go.id domains, to boost their ranking in search engines. This study aims to develop a keyword-based input detection and blocking mechanism to prevent the insertion of online gambling content into websites. The method employed is Fuzzy Matching with the Levenshtein Distance algorithm, which measures the similarity between user input and gambling-related keywords. The evaluation results show a precision of 1.00, recall of 0.80, F1-score of 0.89, and accuracy of 0.90. These results indicate that the system can detect sentences containing gambling elements with high accuracy; however, false negatives still occur and need further improvement to be minimized. Thus, this mechanism can serve as an initial step in preventing the misuse of websites by cybercriminal groups.
