Improvement of wastewater quality of Dhaleswari river, Bangladesh using submerged macrophyte Egeria densa
Get PDFClean water is one of the significant goals among the 17 Sustainable Development Goals (SDGs), which will be achieved by at least 2030. It includes six outcome-oriented targets- improve water quality, wastewater treatment, ensure freshwater supplies are three of them. In Bangladesh, Freshwater ecosystem is continuously degraded due to rapid industrialization, which occurred along the riverside areas. In this context, laboratory-based work has been conducted to analyze the water quality of Dhaleshwari River, Bangladesh, which has already been polluted by industrial waste. The collected water samples were treated by submerged macrophyte Egeria densa to observe the changing water quality parameters. The growth of plants and roots were assessed after 10 days of exposure to three categories of water treatment. Initial and final water quality parameters were observed by the analysis of pH, EC, TDS, TSS, Acidity, Alkalinity, Total Hardness, Ca Hardness, COD, Sulphate (SO42-), Phosphate (PO43) Total Chlorine (Cl-) and Copper (Cu2+). The result showed that almost all the toxic parameters of water were reduced significantly at the end of the experiment. The present study hypothesized that submerged macrophyte E. densa can be used as a potential tool to upgrade the water quality of polluted rivers.Keyword: Clean water, Submerged macrophyte, SDG 6, Dhaleswari River, Freshwater ecosyste
SOSIALISASI PEMBERDAYAAN DAN PERAN PENTINGNYA DIGITALISASI GUNA MENINGKATKAN PRODUKTIVITAS UMKM
Get PDFThis activity is an UMKM empowerment program and the importance of digitalisation to increase the productivity of UMKM in Balikpapan city. This activity is a form of concern for economic development from the UMKM sector. The socialisation was conducted in Manggar Baru urban village, Balikpapan city. From this socialisation, it can be seen that the knowledge of the community of UMKM business actors is still lacking in understanding the use of technology to brand the products produced. With the socialisation programme, it is very helpful for the community to improve their business products including introducing them to consumers. Therefore, the socialisation on the importance of digitalisation for UMKM in Balikpapan City has succeeded in increasing the interest and understanding of business actors on the use of digital technology. The digitalisation of UMKM gives a positive impact to increase productivity and improve people\u27s welfare. Utilisation of digital technology in the form of social media provides efficiency in terms of time, energy, and cost, increased market reach, and improved service quality
