Abstract

Penelitian ini bertujuan mengembangkan papan informasi digital terpadu berbasis Internet of Things untuk menampilkan informasi akademik di Program Studi Pendidikan Teknik Elektronika Universitas Negeri Jakarta. Sistem mengintegrasikan aplikasi Android, Firebase Realtime Database, dua ESP32, dua sensor DHT22, dua sensor PIR, dan dua unit papan informasi berbasis LED matriks (enam modul P10). Sistem bersifat terpadu karena menggunakan satu aplikasi Android dan satu basis data Firebase yang mengelola kedua papan informasi berdasarkan identitas perangkat masing-masing ESP32, sehingga tidak memerlukan aplikasi maupun basis data terpisah untuk setiap papan. Firebase berfungsi sebagai media penyimpanan dan pertukaran data antara aplikasi Android dan ESP32. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model pengembangan V-Model, meliputi tahap analisis kebutuhan, desain sistem, desain arsitektural, desain modul, implementasi (coding), pengujian unit, pengujian integrasi, pengujian sistem, dan pengujian penerimaan. Hasil pengujian setelah diterapkan koreksi menunjukkan sensor DHT22 memperoleh rata-rata persentase galat (mean absolute percentage error) suhu sebesar 0,72%, setara dengan selisih rata-rata 0,22 °C, dan galat kelembapan sebesar 2,40%, setara dengan selisih rata-rata 1,74 %RH, dibandingkan terhadap alat ukur pembanding thermohygrometer HTC-1 yang bukan merupakan alat standar kalibrasi. Sensor PIR berhasil mendeteksi gerakan manusia dengan tingkat keberhasilan 100% pada jarak 1 m hingga 4 m, menurun menjadi 86,7% pada jarak 5 m, 53,3% pada 6 m, dan 33,3% pada 7 m. Pengujian pemilihan papan berdasarkan identitas perangkat menunjukkan kedua unit ESP32 berhasil menerima dan menampilkan data sesuai dengan papan yang dituju secara tepat. Pembaruan informasi berhasil ditampilkan pada 19 dari 20 percobaan, merupakan hasil gabungan dari kedua papan (95%), dengan rata-rata waktu respons 3,44 s. Berdasarkan hasil tersebut, dapat disimpulkan bahwa sebagian besar fungsi utama sistem papan informasi digital terpadu telah memenuhi skenario pengujian yang ditetapkan, meskipun masih ditemukan kendala berupa tampilan simbol tertentu yang tidak sempurna dan artefak visual (flicker) pada LED matriks. ***** This study aimed to develop an integrated Internet of Things (IoT)-based digital information board to display academic information at the Electronics Engineering Education Study Program, Universitas Negeri Jakarta. The system integrates an Android application, Firebase Realtime Database, two ESP32 units, two DHT22 sensors, two PIR sensors, and two information boards based on LED matrices (six P10 modules). The system is considered integrated because a single Android application and a single Firebase database manage both information boards based on each ESP32's device identity, eliminating the need for separate applications or databases for each board. Firebase functions as the medium for data storage and exchange between the Android application and the ESP32 units. The research method used was Research and Development (R&D) with the V-Model as the system development model, covering requirements analysis, system design, architectural design, module design, implementation (coding), unit testing, integration testing, system testing, and acceptance testing. The test results show that the corrected DHT22 readings achieved a mean absolute percentage error of 0.72% for temperature, corresponding to a mean absolute difference of 0.22 °C, and 2.40% for humidity, corresponding to a mean absolute difference of 1.74 %RH, compared against an HTC-1 thermohygrometer, which is not a calibration-standard instrument. The PIR sensors achieved a 100% detection success rate for human motion within a range of 1 m to 4 m, decreasing to 86.7% at 5 m, 53.3% at 6 m, and 33.3% at 7 m. Board-selection testing based on device identity showed that both ESP32 units correctly received and displayed data intended for their respective boards. Information updates were successfully displayed in 19 of 20 combined trials across both boards (95%), with an average response time of 3.44 s, while one trial on the first board failed because it exceeded the defined success time threshold. Based on these results, it can be concluded that most of the main functional requirements of the integrated digital information board system were met under the tested conditions, although issues such as imperfect rendering of certain symbols and visual flicker artifacts were still observed on the LED matrix display.
