Abstract

One variation of functional beverages that is beneficial for the body is powdered goat milk with the addition of kenikir leaf powder (Cosmos caudatus Kunth). Kenikir leaves not only contain bioactive compounds that act as antioxidants, anti-inflammatory agents, and antimicrobials, but they also have high levels of protein, phenolic compounds, carbohydrates, vitamins, and minerals. Therefore, kenikir leaves are utilized as a component to enhance the protein content in functional beverages. The effect of adding kenikir leaf powder to functional beverages on protein content was assessed using the Kjeldahl method, with sample formulations labeled MF(F0), MF(F1), and MF(F2). The results from the Kjeldahl method showed that the highest protein content was found in the MF(F2) sample at 3.58%, while the MF(F1) sample had a protein content of 3.07%, and the MF(F0) sample had 2.49%. This demonstrates that the addition of kenikir leaves increases the protein content in functional beverages. Keywords: kenikir leaves, functional beverages, protein, goat milk.

Abstract

Indonesia, the largest palm oil producer, produces a very large of palm kernel shell waste. This study aims to optimize utilization of this waste by converting it into activated carbon which has high potential adsorbent. Process   making activated carbon involves carbonization and activation of palm kernel shells, followed by surface modification using   magnetic particles and organosilane triethoxyiphenylsilane (TEPS). Addition of Fe3O4 particles can increase adsorption capacity and facilitate the separation of the adsorbent from the solution after adsorption process. Meanwhile, addition of TEPS compounds increases the number of functional groups on the surface of activated carbon so   can interact more strongly with dye molecules. Characterization using various techniques such as UV-Vis, FTIR, XRD, SEM-EDX, and BET was carried out to analyze changes structure and surface properties of activated carbon after modification. The results of the study can contribute to   development of waste processing technology and production of value-added adsorbent materials.
