Water quality is a problem because of the large amount of waste generated by human activities. This waste includes things like wastewater from households, factories, and other activities. Therefore, an effective micro-organism-4 (em4) is needed to treat wastewater. The purpose of this study was to determine whether the use of EM4 can reduce the amount of pollutants in hospital waste. The research method used is a laboratory experimental method used to study the effect of the variables studied. Experiment using the formula . The results of this study show the effectiveness of pollution levels using EM4 culture with a time of 16 days with the highest efficiency value found on day 16 in each parameter. Treatment on day 0 shows BOD 20.035 mg/L until treatment on day 16 results in BOD value of 6.087 mg/L and the second repetition (Y2) treatment on day 0 shows BOD value of 20.022 mg/L until treatment on day 16 BOD value is 5.022mg/L. It shows that the mean (Mean) BOD decreased from the initial concentration of 20.029 at 0 days to 5.555 at 16 days treatment.

The research method used is a survey with a quantitative approach. Data were analyzed using correlation and simple linear regression. This research was conducted on residents of Kampung Pulo slum relocation who were moved to West Jatinegara flats, East Jakarta, DKI Jakarta Province. This research was conducted from January to June 2022. The population of this study is 125 people of Kampung Pulo who were relocated to the West Jatinegara flats, East Jakarta. The sampling technique used is non-probability sampling, which is incidental sampling. The number of samples in this study using the Slovin formula of 95 Kampung Pulo people who were relocated to the West Jatinegara flats, East Jakarta. The results showed that the analysis obtained the regression equation = 32.185 + 0.603 X interpreted that every change in the Slum Settlement Relocation variable score (X) was 1 point, it can be estimated that the Environmental Health Quality score (Y) would change by 0.603 in the same direction with a constant of 32,185. The results of the t-test for tcount of 7.068 are greater than ttable (95) of 1.661 at = 0.05. The significance value (sig.) of 0.000 is smaller than = 0.05. This means that there is a positive (7.068) and significant (0.000) effect between Slum Relocation (X) on Environmental Health Quality (Y). The conclusion of the t test results is that there is a significant positive effect between Slum Relocation (X) on Environmental Health Quality(Y). This means that the more the relocation of slums to the West Jatinegara flats, East Jakarta, DKI Jakarta Province, the quality of environmental health will also increase. The correlation coefficient of the effect of Slum Settlement Relocation (X) on Environmental Health Quality (Y) (R) of 0.591 is included in the category of moderate relationship (Table 3.3: Medium = 0.40 – 0.599).

The study used a descriptive method with a qualitative approach. The results showed the ranking of severity scale, failure mode with the highest scale with a value of 10 is the object falling on the lifting by crane activity and on the type of accident the collapsing excavation wall fell upon workers on the activity. The smallest severity scale of failure mode is exposed to UV rays for a long time with a scale of 2. The occurance scale, the highest cause of failure mode is a sling or broken steel rope with a value of 7 in lifting by crane activities. As for the occurance scale, the lowest cause of failure mode is the distance between workers too close to the value of 1 on the activities of road, drainage, foundation. The highest scale of detection, cause of failure mode is to ensure the condition of the equipment before work begins with a value of 7 in lifting by crane activities. The lowest detection scale is the distance between workers too close to the value 1. The highest RPN calculation result is the lifting by crane activity that causes the object to fall, with an RPN value of 490.
