Abstract

Temulawak (Curcuma xanthorrhiza Roxb) contains an active ingredient called curcuminoid which is a substance that has many benefits in the health field. The active ingredient of high heat sensitive curcuminoids for the dryer temperature uses relatively moderate temperatures and with low RH. This research using combination solar molecular sieve, where the air from environment is first passed through a molecular sieve box and then passed to the collector and then to the drying chamber in contact with the dried material. The operating air speed conditions to the dried material varied 1,2, and 3m/s and thickness of varied 25, 50 and 75mm. Reserch aims to study and obtain the best drying process and effect operating conditions on dry temuawak quality. Drying is done at 8:00 am to 4:00 pm. with an initial moisture content of 85%. Dry Temulawak was analyzed according to parameters of SNI 8171: 2015. The results showed that the best air velocity at 3 m/s with a thickness of 25mm obtained the highest drying rate of 0.226gr/cm2hour. The best quality of dry ginger is in the condition of drying 2 m/s with a thickness of 25mm produced dry ginger with moisture content below 10% and curcuminoid value of 1,46%.
