Abstract

The purpose of this PKM is to improve the welfare of target housewives through management, production, marketing and community assistance in making shredded salted fish made from grouper fish. The method applied is in the form of production technology transfer, packaging, marketing, business financial accounting management, website creation and business partnerships with users. PKM is carried out in production houses owned by the community independently. The results of the PKM are in the form of production of shredded salted fish made from grouper by housewives with the skills and capabilities of production, marketing, and financial management that are carried out independently. The group already has marketing partners and permanent raw material sourcing partners. Their product of shredded salted grouper is named Assahra. This business has at least provided new jobs for ± 7 housewives, including additional income for them. The conclusion from this PKM activity is that the production of shredded Assahra grouper is feasible to continue and can be managed independently by the target community, providing new work barriers, additional income and the product of shredded salted grouper is favored by consumers.

Abstract

The potential uses of ecologically benign nickel nanoparticle manufacturing in various sectors, such as biomedicine, energy storage, and catalysis, have garnered much interest. This paper covers green approaches to nickel nanoparticle manufacturing, which integrate natural substances as stabilizing and reducing agents with eco-friendly processes. Phytochemicals derived from bacteria, microorganisms, and plant leaf extracts can convert nickel ions (Ni2+) into nickel nanoparticles. Room temperature is used for the synthesis procedure, and neither dangerous compounds nor unusual reaction conditions are used. Using a variety of analytical methods, the resultant nickel nanoparticles were characterized. We also investigate the possibility of using the generated nickel nanoparticles as a cytotoxic, photocatalytic, antioxidant, and antibacterial agents. The antimicrobial activity of nickel nanoparticles demonstrates their potent antibacterial properties, while their antioxidant activity demonstrates their capacity to combat free radicals effectively. Furthermore, nickel nanoparticles' cytotoxic activity demonstrates their capacity to kill cancer cells, and their photocatalytic activity demonstrates their efficiency in breaking down organic contaminants. This review highlights the value of ecologically benign synthetic methods and creates new avenues for developing nickel nanoparticle applications in health and the environment.
