Background:Moringa oleiferais a fast-growing, long-lived plant that blooms throughout the year and can withstand extreme arid conditions. Objective:This study aims to examine the effectiveness of Moringa oleiferaseed powder in reducing nitrate levels in river water. Method:The research method employed in this study involved analysis using the Paired Sample Statistical Test. Result:The statistical test results revealed a significance value of 0.017 (p < 0.05) and a mixing time variation significance of 0.011 (p < 0.05). These values indicate that the null hypothesis (H0: there is no relationship between the independent and dependent variables) is rejected, while the alternative hypothesis (Ha: there is a relationship between the independent and dependent variables) is accepted. This implies a significant difference in the reduction of nitrate levels between the pretest and posttest data, demonstrating that the use of Moringaseed powder is effective in reducing nitrate levels. Conclusion:This study concludes that the administration of Moringaseed powder at a dose of 400 mg/L, with a mixing time of 2 minutes at a fast speed (80 rpm) and 20 minutes at a low speed (40 rpm), is most effective in significantly reducing nitrate levels in river water. Keywords:Moringa oleifera; nitrate levels; river water; Indonesia

Introduction: Mining activities carried out by PT. X is very detrimental to the environment of residents in Village X. Due to the activities of the nickel mining company, people's rice fields in several villages in Tinanggea District, especially Village X are polluted with mud so that rice growth is hampered and often fails harvest. Method: This type of research is descriptive and quantitative. Samples data was 30 people in X Village Tinanggea District. The data that has been collected in the study were analyzed descriptively. Result: The results of this study are community knowledge that mining activities are a response to community responses, namely (93.3%), community knowledge that activities that arise from these responses are informants (93.3%) and Nickel mining in Village X does not cause health problems with a response in the form of (56.7%). Conclusion: Nickel mining activities have positive impacts, such as: increasing ROI from the mining sector, creating job opportunities, and opening up areas from isolation. Nickel mining activities have a negative impact. Such as the occurrence of environmental damage, like river water becoming blurry and colored and dirty,air pollution, and changes in community behavior.

Introduction: Air quality is strongly influenced by activities carried out by humans. This study aims to determine the NO2 air quality around the Konawe industrial area as well as community activities and respiratory disorders experienced. Method: The data used is a linear regression statistical test to determine the relationship between NO2 air quality with community activity and respiratory disorders. Result: This research was conducted in 6 villages around the Konawe industrial area. Most people carry out their daily activities around the industrial area, so some people experience respiratory problems. In the regression analysis, it is known that the activities of residents of the house affect the concentration of NO2 by 4% and the concentration of these pollutants affects the respiratory disorders of residents of the house by 25%. Conclusion: The conclusion in this journal is that smoking activity in the house is not related to the concentration of NO2 in the air and respiratory problems experienced by residents of the house are also not related to the concentration of NO2 in the house. This study provides awareness that air quality in the house is important to maintain the health of residents of the house and to provide input for residents of the house to reduce activities that can interfere with air quality in closed rooms.
