Abstract

The utilization of coffee husk waste (cascara) as a functional drink still faces obstacles due to low consumer acceptance because of its less favored taste and aroma. This study aimed to determine the effect of cascara tea formulation with the addition of ginger and roselle on physicochemical quality and consumer acceptance. The study used a Completely Randomized Design (CRD) non-factorial with four treatments and three replications, namely C0 (100% cascara), C1 (50% cascara + 50% ginger), C2 (50% cascara + 50% roselle), and C3 (40% cascara + 30% ginger + 30% roselle). Parameters observed included moisture content, pH, organoleptic characteristics (aroma, color, taste), and total phenols in the best treatment. The results showed that the formulation had a significant effect on pH (P<0.05), aroma, and taste (P<0.01), but no significant effect on moisture content and color (P>0.05).. The best treatment was obtained in C3 with an aroma score of 3.84 and a color score of 4.50. Analysis of total phenols in the best treatment showed a value of 44.39%. The combination of cascara, ginger, and rosella can improve consumer acceptance and produce an herbal drink that has the potential as a source of natural antioxidants.

Abstract

Crude Palm Oil (CPO) still contains various impurities that can lower the quality of the oil, thus requiring a refining process to improve its quality. This study aimed to evaluate the effectiveness of palm shell activated carbon modified with sodium alginate as an adsorbent in CPO refining. The study employed a non-factorial Completely Randomized Design (CRD) with five levels of sodium alginate concentration (0%, 1%, 2%, 3%, and 4%) and three replications. The observed parameters included water content, impurities, free fatty acids (FFA), and the Deterioration of Bleachability Index (DOBI) value. Data were analyzed using ANOVA at a 95% confidence level. The results showed that the treatment had a significant effect (P<0.05) on all parameters. The lowest moisture content was seen in treatment N3 at 0.085%, while the lowest impurity content was in treatment N1 at 0.384%. The lowest free fatty acid value was in treatment N0 at 45.590%, and the highest DOBI value was also in treatment N0 at 0.57. The study shows that activated carbon made from palm oil shells with added sodium alginate could be a good alternative adsorbent for the CPO purification process because it can really help improve the quality of crude palm oil.
