Ginger can be used in the form of dry powder or the form of ginger essential oil. Ginger essential oil has properties: it is unstable and susceptible to oxidation and degradation in the presence of oxygen, light, metals, and high temperatures. Encapsulation is a solution to maintain the quality of red ginger essential oil. This study provides information about the drying process of red ginger with a rotary dryer, extraction kinetics using the soxhletation method, and encapsulation of red ginger essential oil. 1.5 kg of red ginger cut into cubes with dimensions of ± 4 mm 3. The pieces of red ginger were put into a rotary dryer which rotated at a speed of 19, 30, and 55 rpm. The dried ginger pieces were then mashed. The ginger powder was extracted in a socket at a temperature of 70 o C using n-Hexane as solvent. The resulting ginger essential oil was then encapsulated in Alginate-PVA beads. Drying with a rotary dryer was still less effective in drying red ginger with a maximum moisture content of 20%. The extraction process using the Soxhlet method with n-Hexan as a solvent resulted in a yield of 7.834% (extraction kinetic constant of 0.211). Ginger essential oil can be encapsulated in Alginate-PVA beads with an average diameter of 1.25 mm.
