Antioxidant activity of seaweed (Eucheuma cottonii) and coconut (Cocos nucifera) masks

Abstract

The processing of agricultural products is one of the pillars of the development of agro-industry in an area. In LabuhanKertasari Village, the main products from the agricultural sector are seaweed, hybrid maize, and coconut. However, farmers only sell agricultural products in the form of raw materials without processing them first. Processed products certainly have a higher economic value than raw materials. For this reason, this research was conducted to process seaweed and coconut into masks which were then tested for the antioxidant activity of the masks that were processed. The research conducted was a laboratory experimental study where seaweed and coconut were first processed into a powder. The treatment given is processing seaweed into powder with an alkaline process and without an alkaline process. Then, mixing seaweed powder and coconut powder with three ratios, namely seaweed powder: coconut powder (1: 1, 2: 1, 3: 1). The results showed that the antioxidant activity of the masks 1: 1, 2: 1, 3: 1 were 743,9 respectively; 513.69; and 406.23 (with alkaline seaweed powder) and 193.67; 174.09; and 149.10 (with seaweed powder without alkalization). The result showed that a mask with a ratio of 3: 1 without the alkalization process is the mask with the highest antioxidant activity value and suitable for the skin.
