Abstract

This Community Service activity aims to assist SMK Imtaq Darurrahim in developing a web-based information system to serve as a medium for disseminating school information and facilitating new student registration online. The system was designed and built using PHP with the CodeIgniter framework and MySQL as the database. The development process employed the Waterfall model, which includes the stages of requirement analysis, system design, implementation, testing, and maintenance. The system comprises three main modules: Information Media (announcements, news, gallery, and contact), Registration System (online registration form), and Management Dashboard (for content and registration data management by school staff). Implementation was carried out through training sessions for the admin and school staff to ensure independent system management. Black box testing showed that 96% of the system’s functions operated correctly, while 4% experienced minor bugs that were subsequently fixed. Server stability testing over a three-month period recorded a 99.8% uptime with an average response time of 1.2 seconds. Security testing identified one minor vulnerability, which was immediately resolved. Overall, the information system effectively meets the school's needs in delivering timely information and simplifying the online student registration process, with reliable performance and security.

Abstract

The increase in indoor temperature and humidity often leads to discomfort and excessive energy consumption in conventional fans operated manually. This study aims to develop a smart fan system based on the Internet of Things (IoT) with adaptive control, capable of monitoring temperature and humidity in real-time and adjusting fan speed automatically or manually via a smartphone application. The system was built using a DHT11 temperature and humidity sensor, a NodeMCU ESP8266 microcontroller, and the Blynk IoT platform as the primary interface. Test results show that the sensor achieved an accuracy of ±0.8°C for temperature and ±3% for humidity, with an average data transmission latency of < 2 seconds and a fan response time of < 1 second. The system operated stably for approximately 1 hours without connection interruptions. By applying adaptive control through hysteresis logic, the system has the potential to reduce energy consumption by dynamically adjusting the fan duty cycle compared to conventional fans. This development contributes to creating an adaptive, comfortable, and energy-efficient indoor environment.
