Abstract

Nanotechnology is a branch of science that investigates materials on a scale of 1-100 nanometers. One method that is often used to create copper nanoparticles is biosynthesis using plant extracts because it is more environmentally friendly, does not use toxic reagents and solvents and the process is simpler. Dragon fruit extract (Hylocereus polyrhizus) has potential as a reducing agent for metal compounds because it contains phenolic and carboxylic groups. This study aimed to synthesize copper nanoparticles (Cu-NPs) using a bio-reductor in the form of dragon fruit extract with various volume variations of CuSO4, pH variations, and stirring time variations. Red dragon fruit extraction was carried out by the maceration method to obtain extracts from dragon fruit, which were then used as a Cu metal-reducing agent. The resulting Cu nanoparticles were characterized using a UV-Visible Spectrophotometer. Based on the data, the highest absorbance value was obtained from the most volume of CuSO4, namely 2 mL with an absorbance peak at a wavelength of 700-750 nm. The optimum pH was obtained at pH 6 with a peak absorbance at a wavelength of 750 nm. The most effective time to obtain the absorbance peak at a wavelength of 700 nm was 15 min.

Abstract

Wringinputih Village, located in the Muncar Sub-district, has potential marine products that can be developed, such as shellfish and shrimp. Lack of socialization and knowledge of the Wringinputih Village community about waste processing and utilization, making the community unable to utilize and process shellfish and shrimp waste. Because of this, it is important to encourage education and socialize or understand the processing and utilization of shellfish and shrimp waste from the smallest scope and empower the community in Wringinputih Village as a form of environmental care and empower Wringinputih Village residents. The method used in this service activity program is a Project-based Learning approach. This method included several stages, namely socialization, practice, application, discussion, monitoring and evaluation and follow-up plans. The level of knowledge of partners who knew about SRF fertilizer increased from 15.91% to 90.00%. It shows the success of the service team in empowering partners. The community can make SRF fertilizer independently and as a solution to the scarcity of fertilizer in Wringinputih Village. The servant will continue to assist the Wringinputih Village community in consistently applying SRF fertilizer on their farms. In addition, the servant will also conduct socialization about business strategies so that SRF products are utilized not only in farming but also as a community business tool.
