Pengaruh Penambahan Bubuk Chlorella Sp. Terhadap Karakteristik Sabun Cair
ABSTRACT
This study aims to analyze the effect of additional Chlorella sp. powder. on the characteristics of liquid soap. The research method used was a non-factorial Completely Randomized Design (CRD) with 4 treatment levels, namely C0 (0 gram of Chlorella sp. powder), C2 (0.68 g of Chlorella sp. powder), C4 (1.36 g of Chlorella sp. powder), and C6 (2.05 g of Chlorella sp powder). Parameter tests performed were sensory analysis (aroma, color, and texture), physical property tests (pH test, free alkali and fatty acid-free analysis, foam stability test, foam power test, net power test, and total plate number (ALT)). The addition of Chlorella sp powder. on liquid soap has a significant effect on sensory values of aroma, color, texture, free alkali, and free fatty acids, and the total plate number (ALT) value of liquid soap produced at the 95% confidence level. On the sensory values of aroma, color, and texture, the best treatment for liquid soap with the additional of Chlorella sp. as much as 0.68 g with characteristics a fragrant aroma, specific to Chlorella sp. powder. with a light green color and a non-clumping, semi-solid, homogeneous, smooth texture, with no coarse grains. The stability, foaming power, and cleaning power of the Cholrella sp. liquid soap of obtained the good quality. The pH, fatty acid, and ALT values of the liquid soap produced also meet SNI, namely pH in the range of 7-10, fatty acids ≤ 4%, and ALT not exceeding 1× 103 (cfu/g).
