The by-product of sludge generated at the Water Treatment Plant can affect water quality degradation if disposed of directly without any prior treatment. As a company engaged in water management, the urban drinking water companies produce sludge in every production activity. This study aimed to identify the flow of sludge generation at the Water Treatment Plant, the quantity of sludge generated at the sedimentation unit, and the quality of the wastewater generated at the Sludge Treatment Plant. The identification results show that the flocculation, sedimentation, and filtration units produce sludge transported to the sludge treatment unit (SCP and SDB). The quantity of sludge generated in the sedimentation unit in March and April are 1,887m3/day and 1,474m3/day, respectively. The physical and chemical quality (pH, temperature, TDS) of wastewater produced by the sludge treatment unit are still below the quality standard based on PERMENLHK No. 5 of 2014, concerning Wastewater Quality Standards for Businesses or Activities That Do Not Have Wastewater Quality Standards.

Waste is a very complex and urgent problem to be solved. The problems occur due to the participation of the residents as the leading actor. This study aimed to determine the significance of the influence of gender, age, education, employment status, income, duration of stay, and the level of knowledge on waste generation and management. Respondents to questionnaires and interviews were 37 people whose numbers were determined based on the Slovin equation, while data was analyzed using SPSS Statistics 20 software. A person's educational status significantly positively affects people's habits in reducing waste generation. The following positive significance was income, gender, and length of stay. Age and employment status have a negative correlation, indicating that the older and working, the less waste the society generates. Besides affecting waste generation, it turned out that education also significantly affects waste management. Therefore, education is the main factor considered in waste planning. The results of this study can be used as input for the Indonesian Government in providing information through training and the provision of waste management facilities.

Namorambe Sub-district is located in a lowland area with 100 mm/day rainfall intensity. The lack of green open land exacerbates rainwater infiltration due to rampant housing developments. This problem has resulted in some Namorambe being subject to annual flooding. An inundation of 10-30 cm can damage infrastructure, disrupt economic stability, and threaten public health. To overcome this problem, the team provided socialization and training and made a rain garden at the Ridho Residence as a pilot model for the community. By looking at the social life in this very friendly housing and the people who live by having a sense of togetherness and living together, the team is confident that the program that has been implemented can be sustainable. The community is expected to feel the program's social, economic, and health benefits. It is one of the most effective ways to introduce rain gardens to the community in Namorambe District. With the provision of rain runoff management training through the application of a rain garden for residential property managers, the selling price of housing can be increased because it is equipped with facilities that make residents safer and more comfortable.

Radin Inten II International Airport is the largest airport in Lampung Province which in 2019 underwent a status change to become an international airport. This article tries to present changes in the acoustic environment caused by flight activities around the airport. Noise measurements were carried out at 12 sampling points in the range of 300-4000 m and under the flight path, which then calculated the noise level (Leq) and the WECPNL index. Contour mapping of noise exposure uses an overlay technique visualized with contour lines. Leq measurement results are 60.4-81.4 dBA with an average value of 69.8 dBA. The distance of the sampling point to the runway is known to have a negative correlation with the noise level, while the noise measured on weekdays and weekends has no difference. The mapping results show that the most affected zones are dense settlements about 600 m from the runway. Three locations are known to fall into the noise level 3 zone, and two other sites fall into the noise level 1 and 2 zones. The non-noise zone is within a 2.5 km distance from the runway. The reduced comfort of living due to noise is a consequence of the economic improvement that may be felt by the people living around the airport.

Urban water management efforts are essential in encouraging the fulfillment of the SDGs targets. One action that can be done is to approach the calculation of the actual water consumption value. This research conducted a survey of domestic water consumption in Bandar Lampung City to obtain comprehensive information. Bandar Lampung City was chosen because it is one of the cities on the island of Sumatra with a high economic growth rate. Lampung Province is the top 3 province in Sumatera Island with the higher Gross Domestic Product Growth on 2022, with Bandar Lampung as its capital city. Furthermore, water consumption patterns were analyzed for various activities, socio demographic conditions, and the community's economy. The results showed that of the 404 samples, the average water usage was 195.08 liters/person/day, with the dominant activities in use including bathing (66.84 liters/person/day), flushing the toilet (35.71 liters/person) / day), and ablution (29.74 liters/person/day). Furthermore, the variable number of family members in one house and income level have significant different on total domestic water consumption. The results obtained in this study are expected to assist in making decisions regarding urban water management plans.

Drainage is one way of removing unwanted excess water in an area and dealing with the effects of excess water in the system. When the rainy season comes, there are almost floods or puddles on urban roads. The large population also makes the volume of drainage channels fill up quickly, while the drainage capacity tends to decrease due to rainwater (erosion) and sedimentation. Meteorological Street, Laut Dendang Village, Percut Sei Tuan sub-district, Deli Serdang Regency, is one of the villages that is frequently flooded every time it rains. On these issues, the researcher highlights the importance of evaluating the Deli Serdang Regency's drainage system along Meteorological Road to anticipate when the rainy season comes. The general exponential method can determine whether the existing drainage volume can still accommodate terrestrial run-off and domestic wastewater in the next 30 years and calculate the population growth. Based on the research results from rainfall data obtained from Meteorology Road, the rainfall intensity value for the last ten years (2010 - 2019) was 10.538 mm/day. Thus, the amount of discharge flowing in the drainage channel (Qplansning) is equal to 0.832 m3/sec, while the planned Q for the next ten years is 0.874 m3/sec, for the next 20 years is 0.953 m3/sec, and 30 years into the future. front is 1.111 m3/sec. Based on the calculation results, Qplans exceeds Qeksisting. Therefore, a new channel plan is needed.

Due to the Covid-19 pandemic, the impact of the lockdown on the water quality of major rivers due to restrictions on activities within the country will have an effect. This research compared the Cimalaya Watershed water quality index values before and during the Covid-19 pandemic. River status was conducted using STORET and Pollution Index based on 2019 and 2020 river quality data. Calculations for each method use the same amount of data and parameters, including TSS DO, BOD, COD, TP, Fecal Coliform, and Total Coliform. The results showed a decrease in concentration for water quality parameters in 2020 or during the Covid-19 pandemic compared to 2019. The parameters that experienced a reduction included TSS, DO, BOD, and COD. But besides that, there has been an increase in water quality parameters in 2020, namely the parameters TP, Fecal Coliform, and Total Coliform. The average STORET and Pollution Index values in 2020 indicated that the river is getting moderately polluted than in 2019. This research can be a preliminary study, but using more parameters and methods will make the analysis more comprehensive.

Most of the area in Klungkung Regency has a waste management system that needs to meet technical requirements regarding the compartment, sorting, collecting, transporting, and processing. Coverage of handling urban waste is still far from the target of 80% in 2019 (46% in 2013), and the amount of waste generation that is still recycled is still minimal (4.95 m3 in 2017). This research aims to make a master plan or strategy implemented to improve service coverage and the quality of solid waste management in the future. This research was conducted by conducting a direct survey and secondary data collection. The strategy adopted is to increase the utilization of waste infrastructure and facilities; increasing the capacity of solid waste facilities according to service targets; improving the quality of landfill management in the direction of sanitary landfills; developing regional final processing site management, and applying waste handling technology that is appropriate and environmentally friendly. The Millennium Development Goals (MDGs) contain the seriousness of improving sanitation conditions, which require increased public access to sanitation facilities in half of the population without access to sanitation. Increased population access to proper sanitation (domestic wastewater, solid waste and environmental drainage) to 100% at the level of basic needs.

Filter membrane technology is known to remove turbidity, colour and microorganisms in water. However, the stability of these parameters during storage is still being determined. This research was conducted to determine changes in pH, turbidity, and total coliform of water treated using membrane filter technology and stored at room temperature and in the refrigerator. Water stored at room temperature increases the pH more easily during storage time. On the other hand, there was no significant difference between changes in the turbidity value of water stored at room temperature and in the refrigerator. Closed storage at room temperature and refrigerators can also protect water from the growth of total coliform. Water treated using membrane filter technology is proven to be stored at room temperature or in the refrigerator without experiencing significant changes in pH, turbidity, and total coliform.
