Abstract

The Final Project Information System (SITASI) website plays a critical role in supporting academic administrative processes at the Faculty of Science and Technology, UIN Sultan Syarif Kasim Riau. This study aims to evaluate the website’s security level following recent maintenance using penetration testing, conducted with the OWASP Zed Attack Proxy (ZAP) tool. The testing revealed eight vulnerabilities, including two classified as medium risk, four as low risk, and two informational. The medium-risk issues involved the absence of an Anti-CSRF token and the lack of a Content Security Policy (CSP), both of which could expose the system to attacks such as CSRF and XSS. The low-risk findings included loading JavaScript from third-party domains, information disclosure via X-Powered-By and Server headers, and the absence of HTTP Strict Transport Security (HSTS). The two informational findings involved suspicious comments in the code and improper Cache-Control settings. Remediation actions were implemented based on OWASP security best practices, including the integration of CSRF tokens, configuration of CSP and HSTS headers, and removal of sensitive information from server responses. A follow-up evaluation confirmed that all identified risks had been successfully mitigated. This study highlights that penetration testing combined with standard-based mitigation is effective in enhancing web application security resilience, particularly within academic environments.

Abstract

This study aims to replace the manual registration system still used by PT Amanah Wisata Group with a web-based digital system. Previously, 80% of the registration process was conducted manually, often leading to errors and delays, including having to wait up to two working days to receive registration forms. The research methodology includes the collection of primary data through interviews with administrative staff and direct observation of the registration process, as well as secondary data from literature reviews and relevant documentation. The system development follows the Waterfall method, consisting of requirement analysis and system design using Unified Modeling Language (UML). The registration system also integrates a Customer Relationship Management (CRM) approach to foster stronger relationships with prospective pilgrims, improve two-way communication, and enable faster and more accurate delivery of Umrah package information and notifications. The results show that the developed system consists of three main modules: an online registration module, a pilgrim data management module, and a payment module. This system enhances administrative efficiency, reduces data entry errors, improves staff performance, and strengthens customer interaction. In conclusion, the web-based information system combined with a CRM approach not only supports the digital transformation of Umrah services but also enhances service quality and the overall experience of prospective pilgrims.

Abstract

Waste is a problem that occurs in many areas. Palembang City is no exception, which will contribute 1,180 tons of waste per day in 2023. One solution that can be offered to reduce the amount of waste scattered around is the existence of a website that provides map information and the location of Temporary Waste Disposal Sites (TPS). This website facilitates the retrieval of information regarding local waste disposal sites, enabling individuals to locate them swiftly and effortlessly, thus promoting the proper disposal of waste at designated areas. For website development, researchers will use CMS Joomla and the Phoca Maps extension. The design stages adopt RAD methodology consisting of requirement planning, user design, construction, and cutover. In the functionality assessment, accurate results were achieved for Map Search and locations categorized by Specific Area Categories and TPS Names. The results obtained from this research are that the website provides information on maps and TPS locations. Joomla CMS, along with the Phoca Maps extension, offers benefits in terms of convenience, affordability, and ease of managing maps and location markers. Additionally, this study presents an alternative perspective on the use of Joomla CMS, which is typically associated with text or image content usage.

Abstract

Lung cancer is one of the deadliest types of cancer worldwide and is often detected too late due to the absence of early symptoms. This study aims to evaluate the impact of feature selection using Mutual Information on the performance of lung cancer classification with the XGBoost algorithm. Mutual Information is employed to select relevant features, including those with linear and non-linear relationships with the target variable, while XGBoost is chosen for its ability to handle large datasets and reduce overfitting. The study was conducted on a dataset containing 30,000 data entries, with data split scenarios of 90:10, 80:20, 70:30, and 60:40. The results show that the testing accuracy before applying Mutual Information ranged from 93.42% to 93.83%, while K-Fold Cross-Validation accuracy ranged from 94.59% to 94.76%. After feature selection, testing accuracy remained stable for the 70:30 and 60:40 split scenarios, at 93.60% and 93.42% respectively. However, K-Fold Cross-Validation accuracy decreased to 89.26% and 90.88%. In contrast, for the 90:10 and 80:20 split scenarios, a decline in accuracy was observed — testing accuracy dropped to 88.63% and 88.85%, and K-Fold Cross-Validation accuracy fell to 88.87% and 90.24%. Feature selection using Mutual Information improves computational efficiency by reducing the number of features, and it can be effectively applied to simplify feature sets without significantly compromising model performance in certain data scenarios, depending on the characteristics of the dataset.

Abstract

The selection of an optimal feature selection method is a crucial factor in improving the accuracy and efficiency of text classification models. Irrelevant features can degrade model performance, increase computational complexity, and lead to overfitting. Although various feature selection techniques have been employed in sentiment analysis, systematic studies comparing the effectiveness of Information Gain and Chi-Square in enhancing classification performance remain limited. This study aims to evaluate and optimize the impact of different feature selection methods on the performance of Support Vector Machine (SVM) and Random Forest (RF) in sentiment analysis. Experiments were conducted using eight testing schemes, including models without feature selection, with Information Gain, Chi-Square, and a combination of both. The results showed that SVM with Chi-Square achieved the highest accuracy at 93%, while Random Forest with Chi-Square achieved the best performance at 91%. These findings indicate that Chi-Square is more effective than Information Gain in improving accuracy, and that SVM outperforms Random Forest in text classification tasks. In conclusion, selecting the appropriate feature selection method significantly contributes to enhancing the accuracy of text classification models. This research can serve as a reference for optimizing feature selection techniques in the development of more accurate and efficient machine learning-based systems.

Abstract

Retrieving contextually relevant verses from the Al-Qur'an translation dataset presents significant challenges due to the linguistic richness and semantic variation of the text. This study aims to enhance the accuracy and relevance of information retrieval in the Al-Qur'an translation dataset by combining Latent Semantic Indexing (LSI) and FastText word embeddings. The proposed method involves several steps: text preprocessing (lowercasing, punctuation removal, stopword elimination, and stemming), tokenization and vocabulary creation, Bag-of-Words (BoW) representation, creation of LSI models, conversion of FastText vectors, and combining LSI and FastText vectors. A similarity index is then created from the combined vectors to process user queries and rank documents based on cosine similarity. Testing on the dataset, consisting of 6236 translated verses from 114 surahs, showed promising results. The combined approach effectively captures both broader semantic structures and detailed word meanings, providing more accurate and contextually relevant search results. Key findings include high similarity scores, with 90% of retrieved verses being highly relevant to the user query, an accuracy improvement to 85%, and enhanced handling of synonyms and morphological variations at 88%. Further development is recommended, including parameter optimization, advanced preprocessing techniques, real-time search optimization, integration of contextual embeddings, and multilingual support to improve search performance and accuracy.

Abstract

The rapid advancement of Information Technology (IT) has made the need for an IT-based teaching and learning concept and procedure inevitable. This concept, widely known as e-learning, has driven a transformation of conventional education into a digital format—both in terms of content and system. Currently, PT Orbit Ventura Indonesia implements a Learning Management System (LMS) to access learning materials, complete, and submit assignments. However, for the Independent Study Program in Cloud Computing, participants also rely on WhatsApp, where mentors deliver learning videos. This leads to an ineffective learning process, as the instructional videos are shared separately through WhatsApp rather than integrated into a unified system. The objective of this study is to develop a simple yet user-friendly video-based Learning Management System. The system is designed as a web-based platform using the CodeIgniter framework, PHP programming language, and MySQL database, with the system development process following the Agile Development Method. As a result, a web-based e-learning platform called Sistem Informasi Ruang Orbit (SIRUBIT) was successfully designed and implemented. This platform is expected to provide both mentors and participants with a more flexible and accessible learning experience—anytime and anywhere.

Abstract

Websites have become an essential medium for information dissemination and marketing, particularly in the context of higher education. Universitas Lancang Kuning has implemented an Academic Information System (Smart Unilak) to improve the efficiency of academic services. However, observations and interviews with the PDDIKTI administrator revealed several issues, including a lack of updated information, difficulties in completing the Study Plan Card (KRS), and concerns regarding data security. To evaluate the system's quality, an analysis was conducted using the WebQual 4.0 and McCall methods. The WebQual analysis showed that the average respondent scores ranged from 3 to 4, which were interpreted as “Satisfactory” to “Very Satisfactory.” Additionally, the McCall method yielded an overall quality score of 89.28%, placing the system in the “Excellent” category. While respondents expressed satisfaction with the information and security provided by the system, there remains room for improvement in terms of communication ease. The findings of this study serve as an evaluation reference for website developers and a basis for future research. It is recommended that subsequent studies incorporate direct usability testing with users to identify issues that may not surface through surveys and questionnaires. Observing users as they interact with the system can provide valuable insights for further enhancement.

Abstract

The objective of this study is to provide an innovative solution to enhance communication between students and university administration by designing a student complaint management system. In this context, the system is designed to facilitate efficient and effective handling of student complaints. Through a web-based application, students can easily submit complaints anytime and anywhere using an internet-connected device. The key features of the developed system include online complaint submission, real-time notifications, complaint status tracking, and a complaint management system that enables university administrators to respond to and resolve issues more promptly. The success indicators of this system include a fast response time—where complaints can be processed quickly—and a high level of user satisfaction regarding the efficiency and ease of use of the system. In this study, we adopted the Waterfall development methodology due to its structured and systematic approach, which facilitates planning and testing at each stage of development. This method allows developers to focus on one phase at a time, reducing the risk of errors during implementation. Furthermore, the Laravel framework was chosen for its ease of management, Model-View-Controller (MVC) architecture—which separates application logic from the user interface—and robust security features to protect user data and system integrity. The results of this study demonstrate that a student complaint system can be successfully designed and implemented, offering an effective solution for complaint management in educational settings. With this system, communication between students and university staff is expected to improve, and issues can be resolved more efficiently.
