Abstract

Indonesia memiliki iklim tropis dengan suhu dan kelembapan tinggi sepanjang tahun yang dapat memengaruhi daya tahan makanan, sehingga perlu disimpan pada suhu yang ideal agar memperlambat proses pertumbuhan mikroorganisme penyebab pembusukan pada makanan. Kotak pendingin konvensional yang memakai es batu belum mampu menjaga suhu tetap stabil di kondisi ideal. Untuk itu, diperlukan sistem pendingin aktif seperti thermoelectric cooler. Agar suhu tetap terjaga di kondisi ideal, thermoelectric cooler perlu dikendalikan dengan sistem yang tepat. Fuzzy logic control dapat diimplementasikan dalam sistem pendingin untuk menjaga stabilitas temperatur kotak pendingin. Tujuan dari penelitian ini adalah merancang bangun kotak pendingin penyimpanan makanan menggunakan thermoelectric cooler dan fuzzy logic control berbasis arduino untuk menyimpan dan menjaga kualitas makanan agar tetap layak dikonsumsi dalam jangka panjang. Penelitian dilaksanakan menggunakan metode Research & Development (R&D). Penelitian menggunakan model penelitian Borg & Gall dengan 4 tahapan awal saja. Perancangan kotak pendingin penyimpanan makanan menggunakan Arduino UNO R3, DS18B20, modul voltage divider, modul ACS712, LED, OLED 0,96 inci, modul AOD4184, TEC1-12706, dan kipas DC. Fuzzy logic control sebagai penstabil temperatur. Kotak pendingin penyimpanan makanan yang dikembangkan menggunakan baterai Li-Ion 18650 BMS 3S 12 V 20A dengan kapasitas 21.600 mAh yang dapat beroperasi selama 95 menit tanpa terhubung ke sumber daya eksternal sehingga kotak pendingin bersifat portabel dan dapat diisi ulang. Hasil penelitian menunjukkan penyimpanan makanan berupa puding menggunakan kotak pendingin berhasil memperlambat proses oksidasi dan pertumbuhan bakteri penyebab pembusukan makanan di temperatur ±2℃ s.d. ±4℃. Penggunaan fuzzy logic control pada kotak pendingin penyimpanan makanan berhasil menghemat daya dan energi sekitar 36% dibandingkan kotak pendingin penyimpanan makanan tanpa fuzzy logic control. ***** Indonesia has a tropical climate characterized by high temperatures and humidity throughout the year, which significantly affects food preservation. To inhibit the growth of spoilage-causing microorganisms, food products must be stored at optimal temperatures. Conventional cooler boxes that rely on ice are generally unable to maintain a stable temperature within the ideal range. Therefore, an active cooling system such as a thermoelectric cooler is necessary. To ensure the temperature remains within the ideal range, the thermoelectric cooler must be controlled by a precise and responsive control system. Fuzzy logic control can be implemented to the cooling system to ensure stable temperature conditions inside the cooler box. The objective of this research is to design and develop a food storage cooling box with thermoelectric cooler and fuzzy logic control based on Arduino to store and maintain the quality of food so that it remains suitable for consumption over an extended period. This research is conducted using the Research and Development (R&D) method. This research adopts the Borg & Gall model, limited to the first four stages only. The cooling box is designed using Arduino UNO R3, DS18B20, voltage divider module, ACS712 module, LED, OLED display 0.96 inch, AOD4184 module, TEC1-12706 Peltier module, and DC fan. Fuzzy logic control is implemented to stabilize the temperature. The developed food storage cooling box utilizes a Li-Ion 18650 BMS 3S 12V 20A battery with a capacity of 21,600 mAh, it capable of operating for 95 minutes without being connected to external power source making the system portable and rechargeable. This research results show that storing food in the form of pudding using a cooling box effectively delayed the oxidation process and inhibited the growth of spoilage-causing bacteria at temperatures of approximately ±2℃ to ±4℃. The implementation of fuzzy logic control in the food storage refrigeration system achieved an energy and power savings of approximately 36% compared to a system without fuzzy logic control.
