The production of bioethanol from microalgae goes through several stages, including cultivation, harvesting, drying, storage, and conversion to bioethanol. Nearly 40% of the total energy consumed in the bioethanol production from microalgae is from drying. This research aims to study the drying rate model of Chlorella pyrenoidosa using an oven. The drying is carried out at the temperatures of 50, 60, and 70 oC. The initial moisture content of Chlorella pyrenoidosa was 317.798% dry weight. The results showed that at the temperatures of 50, 60, and 70 oC, the critical moisture content was 9.108, 7.583, and 6.93% dry weight, while the equilibrium moisture content was 3.172, 3.158, and 3.109% dry weight. The most optimal drying is at 70 oC and the drying rate gets faster as the temperature does too. The Page model is better at describing the drying rate of Chlorella pyrenoidosa using an oven than the Newton model. The drying speed constants (k) were 0.00056, 0.00061, and 0.00208, at 50, 60, and 70 oC, respectively.

Curcuma xanthorrhiza Roxb. (giant curcuma) is one of herbal plants which is easily found in tropical region such as in Indonesia and has been widely used for medical purposes. This plant has been intensively used as the main ingredients of traditional medicines due to its potent healing power. Giant curcuma is generally dried using a conventional way under the sun prior to use. This method was less controlled, thus leading to poorer quality of products. Drying in a controlled batch dryer could improve product quality in overall. This experiment aimed to study the drying kinetics of giant curcuma using a laboratory designed batch dryer. Drying temperatures were varied between 40 ∘ C to 60 ∘ C. Samples were also dried in the oven at corresponding temperatures as the control. The drying was conducted until approximately 11 % dry basis moisture content inside the samples was achieved. In general, the drying time of giant curcuma were shorter when the temperatures were increased. This was also confirmed by Page's Model whereby drying rate constants increased four times both in the batch dryer as well as in the oven when the drying temperatures were increased from 40 ∘ C to 60 ∘ C.
