Abstract

Penelitian ini bertujuan untuk merancang dan membangun sistem penjadwalan otomatis bel sekolah berbasis Internet of Things (IoT) di SMP Swasta TPI Janji yang dapat membantu meningkatkan ketepatan waktu pembunyian bel serta mengurangi ketergantungan terhadap pengoperasian secara manual. Metode yang digunakan dalam penelitian ini adalah Research and Development (R&D) dengan model pengembangan ADDIE yang meliputi tahap analisis, perancangan, pengembangan, implementasi dan evaluasi. Sistem yang dikembangkan mengintegrasikan ESP32 sebagai mikrokontroler utama, RTC DS3231 sebagai sumber waktu, DFPlayer Mini sebagai pemutar audio, MicroSD Card sebagai media penyimpanan suara, speaker sebagai keluaran audio serta website dan backend sebagai media pengelolaan jadwal. Data jadwal yang dikelola melalui website diteruskan kepada ESP32 melalui koneksi WiFi. Selanjutnya, ESP32 membandingkan waktu aktual dari RTC DS3231 dengan jadwal yang telah ditentukan. Apabila waktu sesuai, ESP32 memberikan perintah kepada DFPlayer Mini untuk memutar audio bel melalui speaker. Sistem juga dilengkapi dengan pencatatan aktivitas bel pada backend dan notifikasi WhatsApp kepada penerima yang telah terdaftar dan aktif. Pengujian sistem dilakukan menggunakan metode Black Box Testing untuk memastikan setiap fungsi sistem dapat berjalan sesuai dengan kebutuhan. Hasil penelitian menunjukkan bahwa sistem yang dibangun dapat menjalankan pembunyian bel secara otomatis berdasarkan jadwal, memudahkan pengelolaan jadwal melalui website, mencatat aktivitas pembunyian bel serta menyampaikan informasi melalui notifikasi WhatsApp. Dengan demikian, sistem bel sekolah berbasis IoT yang dikembangkan dapat membantu meningkatkan efisiensi pengelolaan jadwal dan ketepatan waktu pelaksanaan kegiatan sekolah. Kata kunci: Internet Of Things, ESP32, Bel Sekolah Otomatis ============================================ This study aims to design and develop an Internet of Things (IoT)-based automatic school bell scheduling system at SMP Swasta TPI Janji to improve the accuracy of bell ringing times and reduce dependence on manual operation. The research method used is Research and Development (R&D) with the ADDIE development model, which consists of the stages of analysis, design, development, implementation and evaluation. The developed system integrates an ESP32 as the main microcontroller, an RTC DS3231 as the time source, a DFPlayer Mini as an audio player, a MicroSD Card as audio storage, a speaker as the audio output and a website and backend as the scheduling management platform. Schedule data managed through the website is transmitted to the ESP32 via a WiFi connection. The ESP32 then compares the actual time obtained from the RTC DS3231 with the predetermined schedule. When the time matches the schedule, the ESP32 sends a command to the DFPlayer Mini to play the bell audio through the speaker. The system is also equipped with bell activity logging on the backend and WhatsApp notifications for registered and active recipients. System testing was conducted using the Black Box Testing method to ensure that each system function operates according to the specified requirements. The results show that the developed system can automatically activate the school bell according to the scheduled time, facilitate schedule management through the website, record bell activation activities, and deliver information through WhatsApp notifications. Therefore, the developed IoT-based school bell system can help improve the efficiency of schedule management and the punctuality of school activities.
