Abstract

The development of Internet of Things (IoT) technology has provided new opportunities to improve monitoring through the integration of temperature and humidity sensors in wireless networks. This study aims to optimize a wireless sensor network for temperature and humidity monitoring. This study combines an experimental approach with network performance analysis and optimization methods. First, the selection of temperature and humidity sensors is carried out. Next, an efficient and reliable wireless sensor network architecture is designed to collect temperature and humidity data from various locations. The process of sending data from sensors to base stations and integration with IoT platforms are also studied. Furthermore, a series of experiments are conducted to test the performance of the wireless sensor network under real conditions. Analysis of the collected data is used to identify potential improvements in network performance and improve system reliability and responsiveness. The performance parameters evaluated include connection stability, data throughput, energy consumption, and communication latency. The results of this study contribute to the development of a monitoring system that is reliable, efficient, and easy to implement.

Abstract

The fast development of information technology has improved internet availability but also raised exposure to dangerous material, especially pornography. Maintaining a safe online environment for students and the community at large is a challenge for IDN Boarding School. This study develops an adaptive firewall system using Pi-hole and DNS filtering, designed to block access to pornographic websites while preserving academic access. The system was tested through controlled network simulations involving 1000 domain requests, with results showing a 95% success rate in blocking unwanted content. The study adopts a rule-based design approach and includes usability testing with administrators. Findings suggest that integrating DNS-level filtering effectively reduces exposure to harmful content while maintaining internet stability. This research provides a scalable model for educational institutions seeking to enhance digital safety and responsible internet use.

Abstract

This study develops a web-based payment system using PHP and MySQL to overcome the problem of manual recording in course institutions. Many course places still use manual recording that is prone to errors, administrative delays, and difficulties in making financial reports. This system aims to improve efficiency and accuracy by providing a more structured administration solution. Features such as dashboards, monthly and annual payment monitoring, and financial data recaps allow for transparency and more effective data management. The implementation of the system at Loop Coding BSD, Tangerang, has been proven to speed up the recording process, reduce manual errors, and improve financial reports. This system improves operational efficiency, data security, and facilitates evaluation or auditing. Overall, the implementation of this web-based system makes it easier to manage payment data and supports smooth administration and financial management in educational institutions.

Abstract

Student health directly affects the quality of learning and academic achievement. When sleep patterns and daily routines become irregular, students face a higher probability of developing health-related problems. To address this issue, a web-based expert system was designed and developed to detect student health risks based on sleep patterns and daily activities, applying the Certainty Factor (CF) method, with a case study conducted at STIE BPKP. The Certainty Factor method was used to quantify the degree of confidence in a particular health risk by combining symptom data selected by users with certainty weights assigned by domain experts. The system was built as a web application featuring three core functions: symptom data input, diagnostic processing, and output presentation in the form of health risk levels along with actionable recommendations. Functional testing was carried out to verify that each module operated correctly and that diagnostic outputs aligned with the expected Certainty Factor calculations. Findings from this study confirm that the expert system successfully assists students in assessing their health risk levels in a fast and accessible manner. Beyond individual use, the system also serves as a supporting instrument for academic institutions seeking to strengthen health awareness programs among their student population. As a result, this expert system holds practical value as an early-warning tool for student health risk detection.

Abstract

Manual attendance management at SMP Negeri 204 Jakarta has proven to be inefficient and susceptible to data loss and damage. This study aims to develop and validate a QR Code-based attendance application called "E-SMART ABSENT" as a practical effort to support the digitalization of school administration. As part of a community service initiative within the educational sector, the application was developed using the Research and Development (R&D) method with a waterfall development model. The development stages included user needs analysis, system interface design, software coding using Kotlin and Node.js, and comprehensive system testing. Data were collected through field observations, interviews with relevant stakeholders, questionnaire distribution, and documentation. Product feasibility was measured using a Likert Scale ranging from 1 to 5. Validation results indicate that the application achieved a feasibility score of 86% from media experts, 96% from material experts, and 80% from Grade 7 homeroom teachers, all of which fall within the feasible to highly feasible categories. These findings suggest that the application is ready for broader implementation and has the potential to serve as a reference model for digital attendance system development in other schools.
