Abstract

Unpredictable weather conditions often cause outdoor laundry to become wet again, requiring constant manual monitoring. This study presents the design and development of an Internet of Things (IoT)-based automatic clothes drying system that responds to real-time environmental changes and offers remote control via the Telegram application. The system employs an ESP32 microcontroller integrated with a rain sensor, a DHT22 humidity sensor, and an LDR light sensor. Sensor data is processed in real time using predefined threshold values: when rain is detected, humidity exceeds 26%, or light intensity rises above 3500 lux, the ESP32 triggers a servo motor to retract the clothesline. Conversely, in dry and bright conditions (humidity < 25%, light < 3400 lux), the system extends the clothesline. A servo motor is used as the actuator to retract or extend the drying rack. A Telegram Bot is also integrated to deliver real-time notifications and accept manual commands such as /masuk, /keluar, and /status. The development method follows a prototyping approach that includes requirement analysis, hardware-software integration, and system evaluation. Experimental results show that the system achieved over 95% accuracy in detecting environmental changes and responded within 2–3 seconds to commands and sensor triggers. The combination of sensor automation and interactive Telegram control demonstrates reliability and flexibility in smart-home applications. In conclusion, the proposed system provides an effective and user-friendly solution for managing outdoor laundry in variable weather conditions, with promising potential for future enhancements in IoT-based household automation.

Abstract

Applications that are growing rapidly have provided various benefits in various agencies. The office of the Mayor of Nagari Koto Gadang is a government agency whose attendance system for Nagari devices is still done manually using a note. In this study, researchers designed an attendance application using a QR Code which was implemented at the Office of the Mayor of Nagari Koto Gadang utilizing a manual presence system towards a digital system. This application is built with a high level of mobility that utilizes a smartphone device as a media presence. The development method used in the Nagari device presence system uses the Waterfall Model, the design uses UML. The application functions as a QR Code. With this application, the Nagari device presence process is carried out using a smartphone device as a medium. This makes the attendance process easier by using the presence application using an Android-based QR Code. In its implementation, the application will also use Kodular as a function to make scans on smartphone devices.

Abstract

Abstrak: Perkembangan teknologi informasi mendorong instansi pemerintah menerapkan sistem digital guna mendukung efisiensi pelayanan publik, termasuk pengelolaan event dan pendaftaran peserta. Pada Dinas Komunikasi, Informatika Kota Bukittinggi, proses tersebut masih dilakukan manual sehingga penyebaran informasi, pendataan peserta, dan pengelolaan kegiatan kurang efektif dan efisien, serta menimbulkan hambatan seperti lamanya verifikasi data, risiko kesalahan pencatatan, dan keterbatasan akses informasi bagi masyarakat. Penelitian ini bertujuan membangun sistem informasi pendaftaran dan manajemen event berbasis web yang membantu administrator mengelola event, peserta, dan kode akses, serta memudahkan masyarakat memperoleh informasi dan mendaftar event secara online. Sistem dilengkapi fitur registrasi dan login pengguna, verifikasi kode akses, manajemen event, pendaftaran dan manajemen peserta, pengelolaan kode akses, notifikasi email, serta tautan grup WhatsApp event. Pengembangan sistem menggunakan metode SDLC model Waterfall, dengan teknologi Laravel Framework, PHP, MySQL, dan Bootstrap, serta diuji menggunakan metode Black Box Testing. Hasil penelitian menunjukkan sistem mampu menjalankan seluruh fungsi utama sesuai kebutuhan pengguna. Dapat disimpulkan sistem ini mampu meningkatkan efektivitas dan efisiensi pengelolaan event serta mempermudah pendaftaran peserta pada Dinas Komunikasi, Informatika Kota Bukittinggi.
