Abstract
Subsistem kadar ozon pada alat sterilisator belum memiliki fitur untuk kontrol kadar ozon. Karena ozon dengan konsentrasi lebih dari 1 ppm memiliki efek buruk pada kesehatan, oleh karena itu perlu dikendalikan kadar ppmnya agar tidak menimbulkan efek buruk pada kesehatan. Serta belum ada fitur monitoring performa pada sterilisator untuk memantau kinerja alat selama proses sterilisasi berlangsung. Pada subsistem kontrol kadar ozon menggunakan metode fuzzy untuk mengendalikan kadar ozon yang akan masuk ke box sterilisator dengan input error dan delta error kadar ozon serta aktuator berupa motor servo yang dikople dengan valve untuk mengatur derajat buka tutup valve agar dapat mengendalikan jumlah ozon yang akan masuk ke dalam box sterilisator. Hasil penelitian yang telah dilakukan adalah respon peralihan sistem pada konfigurasi close loop dengan FLC jauh lebih lambat dibandingkan dengan open loop. Yang mana pada pengujian open loop untuk mencapai kadar ozon sebesar 3 ppm dibutuhkan delay time (Td) sebesar 6,5 detik, rise time (Tr) sebesar 6,34 detik, peak time (Tp) sebesar 20 detik dan settling time (Ts) sebesar 10,45 detik sedangkan pada pengujian close loop membutuhkan delay time (Td) sebesar 8,05 detik, rise time (Tr) sebesar 10,1 detik, peak time (Tp) sebesar 40,21 detik dan settling time (Ts) sebesar 15,15 detik. Serta fitur monitoring pada sterilisator dapat digunakan untuk memantau kinerja alat, yang mana data ditampilkan berupa nilai angka dan grafik secara realtime dengan delay sekurang-kurangnya membutuhkan waktu 4,35 detik.
