Abstract

Indonesia is a tropical country located on the equator with high sun exposure, so sunscreen is needed to reduce the risk of exposure to ultraviolet (UV) light. In this research, a sunscreen was developed that uses natural active ingredients in the form of lignin made from coconut coir. The aim of this research is to determine the comparison between the mass of coconut coir and the volume of ethanol solution that produces the highest lignin content, as well as the concentration comparison between lignin nanoparticles and commercial sunscreen that produces the highest SPF value. The synthesis of lignin from coconut coir was carried out using an extraction method using ethanol solvent, followed by a hydrolysis process with NaOH and acidification with H2SO4, while lignin nanoparticles were made using a pH shifting method using ammonia and HCl. The lignin nanoparticles formed are then added to the sunscreen's active ingredient. The variables used were the ratio of the mass of coconut coir to the volume of 80% ethanol solvent (1:5, 1:10, 1:15, and 1:20 (w-v)) and the concentration of lignin in commercial sunscreen cream (2%, 4%, 6%, 8%, and 10% (w-w)). The results of the research show that the higher the solvent ratio, the more lignin is produced, but will decrease after reaching the optimum point. The optimal solvent volume occurs at a ratio of 1:15 (w-v) with a yield of 12.94% (w-w). In addition, the higher the lignin concentration, the resulting SPF value will also increase. The best concentration is 10% (w-w) at a solvent ratio of 1:15 (w-v) with an SPF value of 22.23.

Abstract

Exposure to sunlight causes ultraviolet (UV) radiation, which can damage the body cells. Those negative effects can be prevented by using sunscreen, which contains lignin. Lignin has been proven to absorb or reflect      UV radiation effectively. Rice straw was being used as a non-synthetic active ingredient in sunscreen production. This research shows that during the operating conditions of the isolation process, several variables affect yield production, such as the mass of rice straw, temperature and time of isolation. Therefore, this research was carried out to optimize the lignin isolation process using the Box-Behnken Design (BBD) methodology.  Rice straw dregs that have undergone sample preparation were subsequently isolated through hydrolysis using 5% (w/v) NaOH. After that, the product was carried out to the next process, namely acidification, which used 72% (v/v) H2SO4. The resulting precipitate was then filtered and dried in an oven. Subsequently, the fiber content of the product was analyzed using the Van Soest analysis method, while the process conditions were evaluated using the BBD methodology. In this research, the highest lignin yield obtained was 17.04%, and the optimal process conditions used were 30 g mass of straw, 140°C, and 3 hours reaction time.

Abstract

Coffee is a favorite of the Indonesian people, especially with the increase in coffee business after the COVID-19 pandemic, so the demand for coffee raw materials from farmers has also increased. Residents of Ketindan village on the slopes of Mount Arjuna, under the guidance of Alir Coffee, take advantage of this condition by cultivating coffee, although the technology used is still simple, and post-harvest waste has not been managed properly. To improve production efficiency and waste management, the Department of Chemical Engineering – State Polytechnic of Malang held PpM activities, namely educating farmers through presentation methods and question and answer discussions, the activity ended by providing feedback to participants and handing over a set of Huller Coffee tools to increase the productivity of coffee farmers. Feedback data processing is done by the Likert scale method. The results of the PkM activity, show that residents are very enthusiastic in attending socialization activities and many participants in question and answer discussion sessions, while the Likert scale results obtained a percentage score of 95% which means that partners are very satisfied with this socialization activity. With the knowledge of post-harvest coffee management and processing, this activity is running smoothly and is expected to increase the knowledge of post-harvest coffee education, increase the economic potential for residents, and can be implemented sustainably.
