Abstract

Penelitian ini bertujuan untuk mengevaluasi tingkat kegunaan (usability) dari aplikasi Laundry Keeper, yaitu layanan digital yang dirancang untuk membantu pengguna dalam mengelola pesanan dan jadwal laundry secara efisien. Evaluasi dilakukan menggunakan metode System Usability Scale (SUS), yang memberikan pengukuran kuantitatif terhadap kepuasan dan kemudahan penggunaan sistem. Penelitian melibatkan 18 responden yang terdiri dari mahasiswa aktif dan pengguna layanan laundry di Politeknik Negeri Manado, yang diminta untuk menggunakan fitur utama aplikasi dan mengisi kuesioner SUS. Hasil analisis berdasarkan rumus standar SUS menunjukkan nilai rata-rata sebesar 68,33, yang termasuk dalam kategori “OK” atau kegunaan yang dapat diterima. Nilai ini menunjukkan bahwa aplikasi mudah dioperasikan, efektif dalam membantu aktivitas pengguna, serta memberikan pengalaman pengguna yang positif. Namun, beberapa aspek seperti konsistensi visual dan navigasi antarmuka masih perlu ditingkatkan agar interaksi pengguna lebih optimal. Secara keseluruhan, aplikasi Laundry Keeper menunjukkan performa kegunaan yang baik dan berpotensi mencapai kategori sangat baik dengan peningkatan pada tampilan antarmuka dan optimalisasi pengalaman pengguna.

Abstract

High indoor air humidity can reduce thermal comfort and potentially affect occupants, equipment, and materials. This study aimed to develop and initially evaluate an Internet of Things (IoT)-based room air-drying system using a SoC ESP32 for automatic humidity monitoring and control. A prototype engineering approach was employed through system requirements analysis, hardware and software design, prototype development, IoT integration, and testing in a small-scale test room. The system integrates a DHT22 temperature-humidity sensor, ESP32, relay, air-drying actuator, and IoT dashboard for real-time monitoring. Initial testing showed that the system reduced relative humidity from 78.6% RH to 61.2% RH, corresponding to a reduction of 17.4 percentage points. The temperature decreased from 29.4°C to 28.8°C during the drying process. The measured sensor accuracy was 97.8% for temperature and 96.4% for relative humidity when compared with a reference measuring instrument, while the average actuator response time was 4.7 s from threshold detection to activation. The system successfully displayed temperature, humidity, and actuator status on the dashboard in real time and operated without significant disturbances during the test. However, the evaluation was limited to a small-scale test room and did not include settling time, overshoot, or long-term humidity fluctuation analysis. Therefore, the prototype demonstrates initial feasibility as a low-cost approach to automatic indoor humidity control and has potential for further development and testing under more diverse room conditions.
