Abstract

Water is a human need to carry out activities ranging from daily essentials to agricultural needs and others. Domestic wastewater must meet physical, chemical, and biological requirements so that humans cannot be polluted by the water, especially the water around the Pasir Panjang Village area in Batam, Riau Islands. This study aims to determine the potential use of water hyacinth for environmental health. This research was conducted by direct observation and measurement of water quality by grab sampling. Observation results show that not all residents use septic tanks as wastewater treatment results from daily activities. Some residents drain their wastewater directly into water bodies or surrounding land, resulting in decreased environmental aesthetics. Water quality testing for nutrient parameters shows that the quality standards have been met. However, further measurements are needed for total nitrogen and phosphate. Besides that, it also causes a population explosion of water hyacinth. In addition to the ability to treat water hyacinth waste, its economic potential is also analyzed. The growth of water hyacinth is sufficient and fulfills its capacity, and water hyacinth can be used for various crafts that can improve the community's welfare.

Abstract

PT. X is a pharmaceutical company that produces wastewater with the potential to harm the environment. Although the company already has a wastewater treatment system in place, this study evaluates its performance through direct field surveys and qualitative analysis based on ideal treatment standards. The treatment system at PT. X uses a series of five stabilization tanks operated in a continuous flow. However, BOD and COD test results from November 2019 to March 2020 show that the treated effluent does not meet the required pharmaceutical wastewater quality standards. This indicates the need to redesign the existing treatment system. One solution is to improve the biological treatment process, as the current BOD/COD ratio of around 0.5 suggests poor biodegradability. In addition, introducing an electrocoagulation process could enhance performance, with COD removal efficiency reaching up to 55.4%.

Abstract

The Covid-19 pandemic has resulted in restrictions on people's daily activities. Including the Yogyakarta area which is famous for its tourism and education center. Changes indirectly allow changes in the rate of waste generation. The purpose of this study was to determine changes in the generation of waste generated in Yogyakarta during the pandemic and before. This study uses secondary data for data on waste generation and population in Yogyakarta City, Sleman Regency, and Gunung Kidul Regency. Analysis was performed using analysis of variance (ANOVA) with software. Waste generation in district areas tends to decrease compared to urban areas. However, judging from the rate of waste generation, the Yogyakarta City tends to decrease, while in the district it is increasing. When viewed from the ANOVA test, there was no significant change in waste generation during the Covid-19 pandemic. This also needs to be a concern where a decrease in waste generation is not always followed by a decrease in the rate of waste generation.
