Abstract

This study aims to determine the chemical characteristics and sensory quality of facial masks with differences concentration of seaweed (Eucheuma cottonii) and rice flour. This research was conducted on March 2017 until December 2017.This research method used randomized block design with four treatments and with 3 replications.The treatments consisted of four treatment levels: A1 = (20% seaweed: 80% rice flour), A2 = (40% seaweed : 60% rice flour), A3 = (60% seaweed: 40% rice flour), and A4 = (80% seaweed: 20% rice flour). Parameters observed were chemical analysis (moisture content and antioxidant activity test) and sensory analysis (homogeneous test, spreading, inherent power and drying time). The results showed that the treatment had a significant effect on the 5% test level of sensory analysis with homogeneous test values (1 - 2.8), attachment power (1.12 – 2.6), spreading (2.08 - 2.88 ), time to dry (3.92 – 4.88). The result of chemical analysis showed that the treatment had no significant effect on water content and acidity. The result of antioxidant activity in sample A1 was IC 50 40.91 ppm, in sample A2 was IC 50 value 35.92 ppm, in sample A3 was IC 50 value 45.81 ppm, in sample A3 was value IC 50 30.57 ppm. The best treatment based on analysis of antioxidant was A4 (80% seaweed: 20% rice flour) with IC 50 value was 30.57 ppm.
