Abstract

The use of sorghum is currently limited to its basic potential, particularly the sorghum grain, which is used as a food ingredient. Sorghum stalks, which produce sap, are typically used as animal feed because they have no economic value. Sorghum is commonly consumed in the form of porridge, bread, chips, and drinks. However, so far, sorghum stalks have only been used for animal feed. Sorghum sap derived from sorghum stalks can be used to make wine, as its composition is higher than sugarcane sap. Wine is made through a fermentation process with the help of Saccharomyces cerevisiae. This study aims to determine the alcohol and glucose levels, organoleptic properties, and polyphenol levels. This study used a Completely Randomized Design (CRD). In this study, the fixed variables used were the glucose content of raw materials, the type of yeast, and pH, while the variable that changed was the % volume of the starter. The experiment was carried out by preparing sorghum sap, then the sorghum sap was poured into an Erlenmeyer flask with nutrients, and added starter (5%, 6%, 7%, 8%, 9%, 10%), operating 21 days and pH 4.3 then analysis of alcohol content and glucose content. The results showed that at % volume of starter 10% and fermentation time 21 days gave the highest alcohol content of 19.5%, glucose content 5.8 brix and total polyphenols 0.3449 mg/mL.

Abstract

The utilization of medicinal plants has become one alternative for communities to treat illnesses. This is because the use of medicinal plants, besides being relatively affordable, also does not cause side effects compared to the use of modern medicine or chemical-based drugs. This study aims to develop a reference book of medicinal plants in Rote Tengah Sub-district, Rote Ndao District. The development model used in this research is the ADDIE model (analysis, design, development, implementation, evaluation). The research results obtained from material expert testing showed a validity of 94.6%, design expert testing showed 95.5%, and media expert testing showed 100%. Overall, the percentage of assessments from all three experts indicates a value of 96.7% with a qualification of very valid (highly appropriate). This indicates a positive response to the developed medicinal plant reference book, which is deemed suitable for use as a learning resource. This is because the developed medicinal plant reference book has its own advantages, where the illustrations in the reference book are made with attractive designs, thus attracting students' attention and making it easier to understand
