Abstract


Proses distilasi uap minyak serai wangi secara konvensional sering mengalami pemborosan energi dan fluktuasi suhu yang berpotensi menurunkan kualitas produk. Penelitian ini bertujuan mengembangkan sistem kendali otomatis dan pemantauan berbasis Internet of Things (IoT) untuk mengoptimalkan efisiensi energi serta menjaga kualitas produk minyak serai wangi. Sistem mengintegrasikan algoritma Fuzzy Logic dua variabel input independen, yaitu temperatur boiler (Tb) untuk mengendalikan heater dan temperatur kondensor (Tk) untuk mengendalikan pompa pendingin, serta platform IoT untuk pemantauan real-time. Pengujian dilakukan selama 120 menit menggunakan 2 kg serai segar dengan membandingkan kinerja sistem berkendali dan tanpa kendali pada kondisi awal yang setara. Hasil penelitian menunjukkan bahwa penerapan Fuzzy Logic mampu menjaga kestabilan operasional pada temperatur boiler 114℃ dan tekanan 78 kPa. Sistem berkendali berhasil menekan konsumsi energi dari 1,82 kWh menjadi 1,50 kWh, atau menghemat energi sebesar 17,6% (0,32 kWh). Selain itu, penghematan energi tidak mengorbankan kualitas produk, ditunjukkan oleh peningkatan rendemen minyak (0,63% vs 0,54%) dan kadar sitral (35% vs 25%) dibandingkan sistem tanpa kendali. Validasi sensor temperatur dan tekanan menunjukkan deviasi rata-rata masing-masing sebesar 4,04℃ (5,6%) dan 1,28 kPa (2,9%). Penelitian ini membuktikan bahwa integrasi Fuzzy Logic dan IoT efektif meningkatkan efisiensi energi sekaligus mempertahankan mutu hasil distilasi uap serai wangi.
