Abstract

Penelitian  ini bertujuan untuk mengembangkansistem kendali kipas yang berbasis Internet of Things (IoT) melalui Telegram bot sebagai bagian dari pengaturan smart home/rumah pintar. Mikrokontroler NodeMCU ESP8266, Base Plate NodeMCU ESP8266, sensor suhu DHT11, relay 1 channel, LCD 16x2, dan kabel jumper untuk koneksi komponen digunakan dalam konstruksi sistem ini. Ketika suhu mencapai ≥30°C, kipas akan otomatis menyala; ketika suhu <30°C, kipas akan mati. Selain kontrol otomatis, pengguna juga dapat mengoperasikan kipas secara manual dengan mengirimkan perintah on atau off melalui Telegram bot. LCD menunjukkan suhu saat ini dan kondisi kipas secara real time. Sistem ini dikembangkan dengan menggunakan metode penelitian prototype, yang terdiri dari 7 tahapan yaitu: mengumpulkan kebutuhan, pembangunan prototype, evaluasi prototype, pengkodean sistem, pengujian sistem, evaluasi sistem, dan penggunaan sistem. Untuk memastikan bahwa setiap fungsi sistem beroperasi sebagaimana mestinya, pengujian dilakukan dengan menggunakan pengujian black box testing untuk menilai fungsionalitas sistem. Hasil menunjukkan bahwa sistem dapat berjalan dengan baik, baik pada mode otomatis maupun manual, serta memberikan kemudahan dalam pengendalian perangkat rumah tangga melalui internet dengan menggunakan Telegram.

Abstract

The rapid development of information technology has encouraged schools to implement digital systems in various aspects, one of which is library management. At SMPN 2 Lamasi, the book borrowing service, which was previously done manually, is now being directed to a website-based system. Through the Human-Centered Design (HCD) approach, this digital library system was developed with consideration of the User Interface (UI) and User Experience (UX) aspects. The HCD approach focuses on user needs and priorities in every stage of the application development process, covering stages from needs analysis to usability evaluation. There are three HCD methods, namely inspiration, ideation, and implementation. The research data collection methods included observation techniques, interviews, and direct testing of users by library staff. The results of the study show that UI/UX design with an HCD approach can improve the usability, efficiency, and user satisfaction of library staff in the book borrowing process at SMP Negeri 2 Lamasi. Thus, this UI/UX design has been proven to be effective in supporting the tasks of library staff without manual recording. The System Usability Scale (SUS) test results showed an average score of 90, which falls into the excellent category with an A grade.
