Abstract

Bacterial cellulose (BC) is a biopolymer resulting from sugar fermentation by exopolysaccharide-producing bacteria. BC production can be done using various agricultural and industrial wastes as raw materials. This makes BC one of the leading choices for green technology. BC produced from coconut water fermentation is known as nata de coco. Nata de coco has several superior properties, including high purity, crystallinity, chemical stability, heat resistance, good water retention capacity, mechanical properties, and biocompatibility. The unique properties of BC allow its application as a support and stabilizer for silver nanoparticles in composite form. The synthesis of silver nanoparticle composites in bacterial cellulose can be done using an environmentally friendly method. In this study, BC was produced from the fermentation of coconut water waste by Acetobacter xylinum bacteria. The characteristics of the resulting BC were studied, including thickness, Water Retention Capacity (WRC), cellulose content, yield, and swelling properties. In addition, the resulting BC is utilized as a support and stabilizer for forming silver nanoparticles. The presence of silver nanoparticles in the BC structure was analyzed using a Scanning Electron Microscope (SEM) and Energy-Dispersive X-ray (EDX). The analysis results showed that the silver content was 22.20% in the BC structure with a fermentation time of 3 days, and 15.52% in BC with a fermentation time of 5 days.

Abstract

The provision of clean and safe drinking water is a fundamental need to support public health. However, in some areas, poor groundwater quality, such as turbidity and high iron content, remains a major issue. This activity aims to address water quality problems in Kalurahan Umbulmartani Kapanewon Ngempak, Sleman Regency, through a community service program with a participatory approach. The activity involved the community in water treatment using a simple filter media consisting of fine sand, zeolite, gravel, and activated charcoal to reduce turbidity and iron levels in the water. The results show that this technique is effective in improving water quality and meeting health standards. Community empowerment through training, socialization, and direct assistance from cadres and related parties successfully enhanced community understanding of the importance of clean water and created positive changes in the independent management of clean water. Collaboration between the Puskesmas, village government, cadres, and local communities played a key role in the success of this program, which also contributed to efforts to prevent stunting in the area.

Abstract

The development of the industries affected the increase of wastewater discharged into the environment. Dye is a pollutant that is quite dangerous for human health and ecosystems. Recently, various methods have been found to treat dyes from wastewater. Ultrafiltration wastewater treatment is one method that has minimal weaknesses. Bacterial cellulose is a promising biopolymer for separation processes due to its biocompatibility. This study applied various culture conditions to determine the optimum ones to produce bacterial cellulose membranes. The resulting B4 membrane has the best MB solution filtration capability, with a %removal value of 73.24%.
