Abstract

This study presents an innovative design of a reactor vessel for Microwave-Assisted Hydro Distillation (MAHD), optimized for household-scale essential oil production. MAHD, as an energy-efficient alternative to conventional distillation methods, was applied through a newly designed reactor that emphasizes heat transfer optimization and energy efficiency. The reactor was constructed from stainless steel 304 with a capacity of 30–50 liters, integrated with a microwave heating system (500–2000 W), and equipped with a copper pipe condenser. Experimental results demonstrated an increase in essential oil yield of up to 30% compared to conventional hydrodistillation, with extraction times significantly reduced (reaching 100 °C in less than 15 minutes at 1000 W). Further analysis identified optimal operating conditions at 450 W with a feed-to-solvent (F/S) ratio of 0.35 g/mL. This design provides a significant solution for enhancing the efficiency of essential oil production in household industries, with potential implications for reducing energy consumption and improving product quality.

Abstract

Daun sirsak (Annona muricata L.) diketahui mengandung senyawa fitokimia, terutama flavonoid, yang berpotensi sebagai antioksidan dan anti kanker. Senyawa flavonoid dapat diperoleh melalui proses pemisahan seperti ekstraksi dengan memanfaatkan gelombang mikro yang mampu mempercepat proses ekstraksi. Penelitian ini bertujuan menentukan kondisi optimum ekstraksi flavonoid dari daun sirsak menggunakan metode microwave-assisted extraction (MAE). Proses ekstraksi dilakukan pada daya 264 W dan 440 W dengan variasi waktu 30, 45, 60, 75, dan 90 menit. Hasil ekstraksi dianalisis berdasarkan rendemen, kadar flavonoid total, dan identifikasi gugus fungsi melalui FTIR. Kondisi optimum nilai rendemen diperoleh pada daya 440 W selama 30 menit dengan rendemen 20,35 %, sedangkan kadar flavonoid tertinggi mencapai 303,642 ppm pada daya 440 W selama 90 menit. Analisis FTIR menunjukkan adanya pita serapan pada 300–3200 cm⁻¹ yang mengindikasikan gugus hidroksil (–OH) khas senyawa flavonoid.
