Abstract

Waung Village is one of the villages located in Krembung District, Sidoarjo Regency which has great potential in the development and conservation of toga. However, residents still have not optimized this potential. The aim of carrying out the Unusida HMTK PPK is as a form of synergy between students and the community to optimize the potential that exists in the village and create a healthy society. The activities carried out include socialization of the program, mapping of the biodiversity potential of medicinal plants in the village, training in planting and conservation of toga, as well as development of processing of toga products. The results of the implementation of the activities that have been carried out are the formation of a toga conservation area and the development of processed toga products in the form of telang syrup, telang chocolate and dry tea

Abstract

The persistence of antibiotic contaminants such as ciprofloxacin (CIP) in aquatic environments poses significant environmental and health risks, necessitating the development of efficient removal strategies. In this work, a zinc ferrite-anchored two-dimensional carbon nitride nanocomposite (ZF@2DCN) was synthesized via a simple calcination and hydrothermal approach to achieve synergistic adsorption–photocatalytic degradation of CIP under visible light. Structural and optical characterizations confirmed the successful formation of a ZF–2DCN heterojunction with high crystallinity, strong interfacial interactions, and enhanced visible-light absorption. The incorporation of ZF reduced the bandgap of 2DCN from 2.8 to 2.6 eV, promoting improved charge separation. Adsorption studies revealed rapid equilibrium within 30 min and multilayer adsorption on heterogeneous active sites, with a maximum adsorption capacity of 11.7 mg g-1. Under visible-light irradiation, ZF@2DCN achieved up to 81% CIP degradation within 60 min, exhibiting an apparent reaction rate approximately 2.5 times higher than that of pristine 2DCN. The enhanced performance is attributed to the strong synergy between adsorption-driven pollutant enrichment and photocatalytic degradation. Overall, ZF@2DCN shows strong potential as an efficient material for antibiotic removal in wastewater treatment.
