Penyebaran mikroorganisme melalui permukaan benda mendorong kebutuhan solusi sterilisasi yang efektif dan minim kontak. Penelitian ini merancang dan menguji Smart Box Sterilizer berbasis UV-C yang dipadukan dengan mist maker (berbahan hand sanitizer 70%) serta sistem kendali otomatis menggunakan Arduino Uno, sensor penghalang IR, servo, dan LCD I²C. Pengujian meliputi :jangkauan deteksi sensor IR,kinerja servo (sudut dan waktu buka/tutup), karakterisasi irradiansi UV-C dan estimasi dosis, serta efektivitas reduksi bakteri pada tujuh benda sehari-hari. Pada kondisi uji utama, irradiansi terukur sekitar 1,01 mW/cm² dengan durasi penyinaran 90 s (dosis ± 90,9 mJ/cm²). Hasil menunjukkan sensor IR efektif mendeteksi hingga ≈4–5 cm, servo membuka/menutup ≈60° dalam ≈2,5 s, dan rata-rata reduksi bakteri mencapai ≈68% (tertinggi ≈87,5% pada salah satu objek). Temuan ini mengindikasikan bahwa rancangan mampu menurunkan kontaminasi mikroba pada permukaan benda dan beroperasi secara otomatis tanpa kontak langsung.
