Abstract

 The need for clean and safe drinking water is increasing, so innovative disinfection methods are needed. This study evaluates the effectiveness of Polysilicone coated with Chitosan-Nanosilver (PCAg) as a disinfectant for drinking water treatment. The synthesis process involves the reduction of silver nitrate (AgNO3) with sodium citrate, which is then combined with chitosan in an acetic acid solution to produce a stable mixture of nanoparticles. This solution was then impregnated into polysilicone foam to create a functional filter media. The experimental results showed that the PCAg were able to effectively remove bacterial contaminants, including Escherichia coli and Total Coliform, from the distilled drinking water samples from 4 CFU/100mL to 0 CFU/100 mL, as per the quality standard of the Ministry of Health of the Republic of Indonesia number 2 of 2023. Analysis of the SEM-EDX characterization method showed an evenly distributed Chitosan-Nanosilver coating on the polysilicone surface, evidenced by the detection of 1.31% Nanosilver and an increase in carbon percentage from 40.16% to 44.98%. In addition, analysis of the FTIR characterization method showed the presence of peaks indicating alkane vibrations, aromatic rings, ester groups, and amine groups typical of chitosan. This indicates that chitosan has been coated on polysilicone. This study concludes that the coating process enables optimal interaction between chitosan, silver nanoparticles, and polysilicone, thus enhancing the antibacterial properties of the material. Thus having a significant ability to eliminate bacteria.

Abstract

The digital transformation and the requirements of SDG 8 have necessitated the incorporation of entrepreneurship into higher education, particularly in accounting education. The MBKM program is a strategic initiative aimed at enhancing experiential learning; nevertheless, research investigating student experiences in this setting is still few. A qualitative phenomenological approach indicates that student participation in the AM program enhances awareness and interest in entrepreneurial professions, especially as edupreneurs.  Field activities improve interpersonal skills, including communication, collaboration, and leadership. Students believe that the incorporation of entrepreneurship into the curriculum is not comprehensive, hindered by insufficient infrastructure support, a scarcity of lecturer role models, and a rigid academic culture.  This study underscores the significance of a transformational and interdisciplinary methodology in accounting education to cultivate an adaptive entrepreneurial ecosystem. Practical implications urge higher education institutions to enhance assistance for the cultivation of entrepreneurial competencies to facilitate the attainment of SDG 8.
