Abstract

This study explores the need for an integrated information system at the Student and Alumni Development Institute (LPKA) of Universitas Muhammadiyah Tasikmalaya to improve the efficiency of student and alumni data management. The current system does not support digital record-keeping or effective communication with alumni, resulting in suboptimal coordination and limited alumni participation in institutional development. The main objectives are to identify requirements for a web-based information system, analyze internal and external factors using the SWOT method, and design a development strategy aligned with institutional targets. A descriptive quantitative approach was used, with data collected through observation, structured interviews, and questionnaires for active students and alumni. Analysis utilized IFAS and EFAS matrices to determine strategic positioning via SWOT. Findings indicate the need for features such as real-time data management, alumni tracer studies, digital reporting, system integration, and responsive two-way communication. SWOT analysis places LPKA in quadrant I (aggressive), suggesting opportunities for digital expansion by leveraging internal strengths and external opportunities. System implementation is expected to enhance operational efficiency, strengthen alumni partnerships, and create a digital ecosystem supporting collaboration between the academic community and graduates.

Abstract

Teacher attendance recording at MTs Darussalam still relies on manual methods prone to delays, recording errors, and administrative inefficiency. This research develops an automated attendance system using Radio Frequency Identification (RFID) technology as a solution to these problems. The designed system enables attendance recording through identification card detection on reader devices, producing direct and accurate attendance documentation. Integration of ESP32 microcontroller with web-based applications forms the core of the system, ensuring centralized and easily accessible attendance data management. Functional testing demonstrates the system's success in executing all planned features. Implementation of the RFID attendance system has potential to enhance discipline, accelerate administrative processes, and promote school management digitalization. Research findings indicate that teacher attendance automation through RFID technology represents a viable alternative to replace manual systems.

Abstract

This study aims to measure the satisfaction level of Honda Vario motorcycle owners by applying the Simple Additive Weighting (SAW) method. SAW was chosen to evaluate various factors, including price, engine performance, fuel efficiency, safety, and riding comfort. A survey was conducted involving 100 Honda Vario owners to gain insights into their experiences. The results indicate that 18 participants were very satisfied, 39 satisfied, 30 moderately satisfied, and 13 dissatisfied. Comfort and fuel efficiency received the highest appreciation among users. Although some respondents mentioned shortcomings in certain features, most still prefer Honda Vario for daily transportation. These findings can assist manufacturers in understanding customer expectations and considering improvements in product quality as well as after-sales service. For prospective buyers, the results offer useful information to help match their choices with personal needs. By using the SAW approach, the evaluation process becomes more objective, supporting better decisions for both users and manufacturers.

Abstract

This study develops an Internet of Things (IoT)-based monitoring system to measure water levels in gallon containers using a load cell as the primary weight sensor. The system enables users to monitor remaining water in real time and prevent unexpected shortages during daily activities. The method involves assembling hardware consisting of a load cell and an ESP32 microcontroller, followed by a calibration process to ensure accurate weight measurements. Programmed through the Arduino IDE, the ESP32 wirelessly transmits processed sensor data to a cloud platform such as Google Sheets or a hosting service for storage and management. Water levels are visualized through a web-based dashboard that presents data in a clear and accessible format. A notification feature alerts users when the gallon reaches a predefined minimum threshold. Experimental results show that the sensor consistently detects weight changes with stable performance throughout the monitoring process. The dashboard successfully displays real-time data reflecting the actual gallon condition. Overall, the system offers an effective and practical solution for automated water-level monitoring in households, offices, and small businesses.

Abstract

Forgetting to close a door may seem like a small thing, but it can cause security issues and reduce comfort levels in homes and workplaces. To address this issue, researchers created a system that automatically detects door status. The system uses a Reed Switch magnetic sensor to check whether a door is open or closed, and uses an ESP32 module to process the data and control the output. The design process included circuit construction, programming the ESP32, and testing how well the sensor responds at different distances from the magnet. When the door is opened, the Reed Switch sends a signal to the ESP32, which then triggers a buzzer alarm. Tests showed that the system works in real time with fast response and good stability under various door movement conditions. The device continued to operate smoothly during long tests of up to 12 hours continuously. Experimental results showed that the sensor works very accurately without much noise interference, while the ESP32 executes its logic state stably even when affected by other environmental factors such as vibration and temperature changes. The system has a simple design, low cost, and uncomplicated installation, making it suitable for homes, offices, or other places that require an automatic reminder of a door being left open. This prototype can also be upgraded with Wi-Fi in the future to enable notifications to be sent remotely via a mobile app. The research shows that the combination of the Reed Switch and the ESP32 can effectively improve security by reducing user errors in everyday activities.

Abstract

Recent developments in the technology of the Internet of Things (IoT) have led to a more convenient and contactless home automation system. This paper presents an IoT-based home lighting automation system using KY-038 sound detection as a trigger. The functioning principle is based on sound intensity exceeding a certain threshold, which is then processed by an ESP32 microcontroller to control lighting via Wi-Fi in real-time without the need for physical switches. This does not relate to any voice recognition system that uses cloud-based processing, but rather provides simplicity and faster response time through local processing. Testing was done on the performance of the system with variations in distance and sound intensity, where each scenario was repeated 10 times for validation purposes Experimental results show that detection accuracy of 90-100% up to 3 meters with response times between 0.8-1.1 seconds. The system has been tested indoors under conditions of low to moderate ambient noise levels and found reliable operation. It can be integrated with IoT platforms for remote monitoring as well as manual control from mobile applications. This implementation will be very convenient for users especially those having limited mobility and can support energy efficiency in smart home environments by activating lights only when necessary.
