Abstract

One of the sea potentials in Aceh is seaweed. Seaweed contains secondary metabolites and antioxidants that are very well consumed because it can act as an antidote/protector from the free radicals. This study aimed to determine the secondary metabolite content and antioxidant activity of seaweed in Aceh.The seaweed that has been macerated then screened for phytochemicals and tested for antioxidant activity by using the DPPH method. The seaweed species found were Gracillaria verrucosa, Sargassum sp., and Chaetomorpha antennina. The results of this study indicated that Gracillaria verrucosa, Sargassum sp., and Chaetomorpha antennina seaweeds were contained by alkaloids and steroids. Flavonoid and saponins were only detected in the types of seaweed Gracillaria verrucosa and Sargassum sp. It was also found that the higher the concentration of the extract, the higher the percentage of IC50 against free radicals. The Sargassum sp. has a stable percentage of inhibition at a 2-10 ppm concentration, so it is recommended in this study to be considered cultivated in Aceh.

Abstract

Molasses fermentation from molasses has been studied as an alternative to renewable energy. The goal of this research was to determine molasses fermentation as an alternative to renewable energy. The goal of this research was to monitor the alcohol concentration and pH levels during the fermentation process. This study employed a completely randomized design (CRD) method with two components. Factor A is the amount of time required for aeration. Molasses dilution is factor B. Factor A was tested across four different time periods: 24, 48, 72, and 96 hours. Factor B was tested using three different ratios: 1: 1.5, 1: 2, and 1: 2.5. The calculations of alcohol content FcalcP = 74.35> Ftable (11; 36; 0.05) = 2.07 and Ftable (11; 36; 0.01) = 2.79 revealed that components A and B had a significant impact on the final alcohol content. The BNJ 1% was calculated to be 0.63. This demonstrates that A4B3 is the most effective treatment. FcalcP = 2.85> Ftable (11; 36; 0.05) = 2.07 and Ftable (11; 36; 0.01) = 2.79, indicating that factors A and B have a highly substantial effect on acidity (pH). The BNJ 5% was obtained at a value of 0.61. This also demonstrates the optimal acidity conditions in A4B3 therapy. Based on these findings, it is clear that aeration for 96 hours and dilution with a 1: 2.5 ratio produce the greatest outcomes and the maximum alcohol content. At a pH of 4.45, the average bioethanol content is 6.31%.
