Abstract

This study explored the relationship between households’ average formal education levels and sanitation practices. Although formal education was intended to prepare individuals for personal and professional life situations, local habits and cultural practices could sometimes be more influential than educational background, as evidenced by urinary habits practiced in the country. These habits played a crucial role in determining whether urine was disposed of in the toilet, processed in a septic tank, or directly entered the drainage system when spilled on the bathroom floor. In this study, the definition of sanitation differed from that previously outlined by the Sustainable Development Goals (SDGs). The SDGs defined sanitation based on the percentage of households that used safely managed services, including handwashing facilities. This study, however, focused on excreta disposal, desludging intervals, septic tank types, and urinary habits, such as whether urine was disposed of on the bathroom floor or in the toilet. These factors were chosen for their ability to accurately reflect the actual conditions observed in the study area. A survey was conducted among 100 households, and data were analyzed using Analysis of Variance (ANOVA). The results revealed no relationship between households’ average formal education levels and sanitation practices. This analysis suggested that other factors, such as cultural beliefs and environmental habits, may have influenced sanitation practices.

Abstract

Microalgae can be an ecological remediation agent known as phycoremediation. Understanding these factors is critical in producing the expected products efficiently. Several factors affect microalgae growth, including nutrients, temperature, pH, CO2 concentration, lighting, microalgae photosynthesis processes, and hydrodynamic factors. Microalgae Chlorella vulgaris has the potential to survive in media contaminated with heavy metal and high salinity levels. It can reduce the concentration of heavy metals in water through several mechanisms. Further research must be conducted to determine the factors influencing microalgae growth. The research was conducted to observe the growth rate of microalgae in a controlled photobioreactor. The cultivation was carried out in a plastic photobioreactor equipped with aeration, lighting, and the addition of nutrients. The first stage of the research was observations on C. vulgaris growth with 30% inoculum and 20% inoculum. The C. vulgaris growth rate is 0.133 cells/mL/day and 0.927 cells/mL/day, respectively. The second stage of the research was observations on C. vulgaris growth with 20‰ salinity, and the variation used is the aeration, 3 L/min, and 4 L/min. The C. vulgaris growth rate is 0.263 cells/mL/day and 0.236 cells/mL/day, respectively.
