Arduino-Based Air Pipe Leak Detection System

Ari Alriawan, Zulfikar Zulfikar — Sat, 29 Nov 2025 00:00:00 +0000

Leakage in water pipelines can lead to significant losses both economically and environmentally. To address this issue, this study presents the design and implementation of a leakage detection system using the Arduino Nano microcontroller and YF-S201 flow sensors. The system works by comparing water flow data at two points in the pipeline. If there is a significant difference in flow rate, the system detects it as a leak and activates a buzzer as an alarm while displaying information on an LCD 16x2 I2C. Testing results showed that the system is able to accurately detect leaks with an average delay of less than 1 second.

An Android-Based Information System for Student Payment Billing

Muhammad Faizal Basri, Siti Sufaidah — Mon, 17 Nov 2025 00:00:00 +0000

The advancement of information technology has encouraged schools to adopt digital payment systems. This study aims to develop a school billing application based on Android, integrated with the Midtrans Core API as an online transaction solution. The application is designed to simplify the payment process for parents and assist school administrators in recording and monitoring transactions automatically.

The development process follows the Rapid Application Development (RAD) method, consisting of planning, design, rapid construction, and implementation stages. The backend is built using Laravel, while the mobile interface is developed with React Native. System testing is conducted using the Black Box Testing method to ensure that all features work as intended, including login, bill display, payment processing, and transaction reporting.

The results show that the application improves efficiency and transparency in managing school payments. This solution enhances accessibility for parents and supports the digital transformation of school administration systems.

Website-Based Student Savings Application

Jojo Adi Kusumah, Siti Sufaidah — Mon, 03 Nov 2025 00:00:00 +0000

Student savings is one of the flagship programs at the Al-Husna Education Foundation, which aims to train students in managing finances from an early age. Through this program, students are taught to set aside some of their pocket money to meet school needs such as uniforms, tuition fees, and other activities. This program also plays a role in shaping the character of discipline, frugality, and responsibility. However, the previous savings management system was still manual, namely by recording transactions in savings books and cash books. This method is prone to cause recording errors, data loss, and a lack of information transparency for students' parents. In addition, manual recording becomes less efficient as the number of transactions increases. To address these problems, a website-based student savings management system has been developed to replace manual processes with automated systems. The system is built using the CodeIgniter 4 framework, the PHP programming language, and the MySQL database. The results of the study show that this system is able to make it easier to record transactions, present reports automatically, and provide fast, accurate, and transparent access to information for schools and parents of students.

Arduino-Based Mosquito Trap Design

Achmad Syauqii, Zulfikar Zulifkar — Sat, 29 Nov 2025 00:00:00 +0000

Mosquitoes are widely recognized as carriers of dangerous diseases such as dengue fever, malaria, chikungunya, and Zika, which pose serious public health problems in tropical regions. Conventional mosquito control methods, including chemical spraying, coils, and fogging, have several disadvantages, such as health risks, environmental pollution, and reduced effectiveness due to mosquito resistance. This study presents the design and implementation of an automatic mosquito trap based on Arduino Uno as a safer and environmentally friendly alternative. The system was developed by integrating temperature and humidity sensors, light sensors, an ultraviolet lamp, and a direct current fan, which were controlled by a microcontroller and relay modules. The operational logic was programmed so that the lamp activated in low light conditions with optimal temperature and humidity for mosquito activity, while the fan provided suction to direct mosquitoes into a container. The device was assembled and tested indoors to evaluate its automatic functionality. Results showed that the system consistently responded to environmental conditions by activating components without human intervention, effectively attracting and trapping mosquitoes. The prototype demonstrated reliable operation, low power consumption, and the potential for practical use in residential areas. This research indicates that an automatic mosquito trap designed with microcontroller technology can provide an effective and chemical-free solution for mosquito control, with the possibility of future development including improved design, alternative energy sources, and wireless monitoring capabilities.

Design and Construction of a Non-Invasive Microcontroller Based Blood Sugar Level Measurement Device

Pradita Vistianingsih, Zulfikar Zulfikar — Sat, 29 Nov 2025 00:00:00 +0000

The design of a non-invasive microcontroller-based blood sugar meter is essential for checking blood sugar levels to ensure blood sugar is always within the normal range for people with diabetes mellitus. This non-invasive blood sugar detector uses a photodiode for reading. This study aims to test and validate the performance of this non-invasive blood sugar meter. The method used is Research and Development (R&D) with the ADDIE development model. Data collection is carried out through the main technique, namely, direct measurement. The trial was carried out through several stages, namely individual testing, small group testing, and field testing. The trial subjects consisted of individuals with a history of diabetes or prediabetes, as well as healthy volunteers who were willing to participate in the study. In this study, the linear regression method was used to analyze the relationship between the results of the device measurements (independent variables) and actual blood sugar levels (dependent variables) obtained through invasive measurements. The results of the study indicate that this tool successfully functions as an alternative to conventional measurement methods, although the accuracy level still requires improvement, with an average accuracy level of 93.45%. The system as a whole has met the functional requirements criteria in terms of the ability to perform measurements, display results via LCD, and transmit data wirelessly. Non-functional requirements such as portability ease have also been met. Comprehensive testing, including black box testing and field trials, proved that system components can function optimally according to the established technical specifications.

Web-Based E-Learning System Optimization for SMA Negeri Ploso

Ady Luthfi Santosa, Munawarah Munawarah — Sun, 30 Nov 2025 00:00:00 +0000

This research focuses on enhancing education at SMA Negeri Ploso by creating a web-based e-learning platform that offers organized access to educational resources, tasks, tests, and interaction between educators and students. The platform was developed to overcome the drawbacks of traditional teaching methods by providing more flexibility, easier access, and improved efficiency for both in-person and remote learning experiences. A qualitative methodology was used in conjunction with a development process that involved analyzing requirements, designing the system, implementing it, and conducting testing. The platform utilizes a structured access model based on user roles for administrators, educators, and students, allowing each group to execute specific functions aligned with their duties. Administrators handle user information, course management, and feedback, educators can upload and oversee educational content and assess students' work, while students can view course materials, turn in assignments, and check their grades. During the testing phase, it was confirmed that all primary functions worked properly and delivered accurate outcomes as designed. The user interface was crafted to be straightforward, easy to navigate, and usable on multiple devices including laptops, desktops, and smartphones. The launch of this web-based e-learning system significantly enhanced the adaptability and effectiveness of the educational process and has the potential for future developments such as incorporating online quizzes, automated feedback, and communication tools to further improve the learning journey.
