Abstract

Prayer is the main act of worship in Islam after the shahada. The procedures for carrying out this act of worship must be orderly and in accordance with the procedures that have been determined. Most learning currently still uses books so it is less effective and informative. Learning can run effectively if all influential components support each other to achieve learning goals. To facilitate learning activities, especially in Prayer Learning, teachers should prepare teaching materials to help make it easier for students to understand the learning material. Therefore, appropriate learning media is needed, one of which is Augmented Reality-based media. The application was created using Unity and Blender and used the Black box testing method by testing the application, lighting and paper type. This application is intended to make students more interested in teaching and learning activities and makes it easier for students to learn so that maximum results are achieved.

Abstract

Equitable healthcare services require the support of information systems capable of presenting data spatially and being easily accessible to decision-makers. However, most of the geographic information systems currently in use still rely on server-based architecture and centralized databases, which demand technical resources and infrastructure that are not always available at the regional level. This research aims to design a client-side WebGIS system to analyze the distribution of healthcare services in Sukabumi Regency. The system was developed using HTML, CSS, and JavaScript technologies with the use of LeafletJS and OpenStreetMap as the base map, as well as GeoJSON and Google Sheets as sources of dynamic spatial and non-spatial data. The client-side processing approach allows the entire process of visualization and spatial analysis to be carried out on the client side without reliance on the database server. The implementation results show that the system is capable of presenting interactive maps, facility distribution analysis, and identifying areas with unmet healthcare service needs. The novelty of this research lies in the implementation of a lightweight, flexible, and easily replicable client-side WebGIS architecture, making it suitable for institutions with limited technical resources in the development of spatial information systems.

Abstract

This study aims to evaluate public satisfaction with the InaRISK application as a national disaster risk information system developed by the National Disaster Management Agency (BNPB). The research is a continuation of a previous study using the same measurement instrument, enabling a longitudinal comparison of service quality. The study applies the Public Satisfaction Index (Indeks Kepuasan Masyarakat/IKM) method based on the Regulation of the Ministry of Administrative and Bureaucratic Reform Number 14 of 2017, which measures nine service elements. Data were collected through an online questionnaire distributed via Google Forms to 2,448 respondents who participated in the InaRISK application socialization webinar in 2025. The results show that the Public Satisfaction Index in 2025 reached 84.54, categorized as “Good”, which indicates an improvement compared to the previous study that obtained a score of 83.46. Among the evaluated service elements, service procedures obtained the highest score and was categorized as “Very Good”, while response speed remained in the “Less Good” category. These findings indicate that the overall quality of InaRISK digital services has improved, although improvements in service responsiveness are still necessary to enhance user satisfaction more evenly. This study contributes to the evaluation of digital public services in disaster management systems through a longitudinal measurement approach.

Abstract

The implementation of a Web Application Firewall (WAF) based on the OWASP Core Rule Set (CRS) aims to enhance web application security; however, improper configuration may lead to false positives that adversely affect system performance and service availability. This study analyzes the impact of WAF false positives on Open Journal Systems (OJS) services deployed in a cloud environment using a server log analysis approach. The data were collected from web server error logs and ModSecurity audit logs that recorded the blocking of legitimate requests during the manuscript submission process due to inbound anomaly scores exceeding predefined security thresholds. The results indicate that WAF false positives caused service failures characterized by HTTP 403 responses, increased submission errors, and a measurable reduction in OJS service availability during the observation period. These findings demonstrate that anomaly-based detection mechanisms in OWASP CRS may misclassify normal application behavior as malicious activity. This study provides empirical evidence based on server logs regarding the impact of WAF false positives on cloud service reliability and offers insights for WAF policy tuning to achieve a balance between security and service availability.
