The aim of this research is to calculate density and growth rate, efficiency of COD, BOD, BOD5/COD ratio and values (r), (kA), and (kV). The research method used a horizontal flow type artificial wetland with Azolla microphylla plants and gravel and sand media. Wastewater comes from mixed wastewater from the inlet point. The reactor used consists of 3, namely, R0 (control), R1 (25% wastewater; 75% clean water), R2 (50% wastewater; 50% clean water). Acclimatization of plants with a load of 25% and 50% of the wastewater of each reactor with 40% initial cover area. The discharge of artificial wetlands is 51,84 m3/day. The results showed that the artificial wetland system with a load of 25% resulted in growth rates ranging from 0,1145 gr/day-0,1682 gr/day at a density of 37,04–118,52 ind/m2, the growth rate with a load of 50% between 0,1030 gr/day–0,2653 gr/day at a density of 37,04 ind/m2–103,70 ind/m2. COD efficiency at plant density with a load of 25% ranges from 15,89%-56,16%, BOD 14,26%-24,33% at a density of 37,04-118,52 ind/m2, COD efficiency with a load of 50% water waste 20,18%-29,55%, BOD 15,52%-22,65% at a density of 37,04-140,74 ind/m2. The removed organic load in COD parameters is 8294-20373 kgCOD/ha/day in reactor 1 and 15759-32348 kgCOD/ha/day in reactor 2, BOD is 7393-12612 kgBOD/ha/day in reactor 1 and 8046-18483 kgBOD/ha/day in reactor 2. Average COD in reactor 1 value (R) 6102 gr/m2/day, kA 38,58 m/day, kV 0,10/day. The average value of COD in the reactor 2 values (r) 8858 gr/m2/day, kA 53,41 m/day, kV 0,14/day. The value of BOD in the reactor 1 value (r) 3754 gr/m2/ day, kA 38,77 m/day, kV 0,10/day. In reactor 2 the average (r) was 4148 gr/m2/day, kA 44,09 m/day, and kV 0,11/day.

PT XY is a company engaged in the production of compressors and automotive components that require precision in their manufacture. Noise in the work environment is a potential hazard for employee health. The purpose of this study was to analyze the noise level at PT XY using manual visualization mapping and noise distribution patterns with the 11 surfer program. This study used secondary data on noise level measurements in March and October 2018 and June and October 2019 from PT XY. with the SNI 7231-2009 method concerning the Noise Intensity Measurement Method in the Workplace which is taken for a moment for 1 hour with an interval of 6 minutes. The noise level measurement tool used is the SL-4011 Sound Level Meter. The data from the measurement of noise levels are compared with the Regulation of the Minister of Manpower of the Republic of Indonesia Number 5 of 2018 concerning Occupational Safety and Health in the Work Environment. From the analysis results obtained are described in the mapping and distribution patterns. From the overall results of the measurement of the noise level of production activities at PT XY, only 3 points exceed the quality standard. The noise level at PT XY ranges from 74 dB (A) - 88 dB (A). Noise level mapping with a visual basic of all noise level measurements, noise sources that exceed the quality standard are in the gasket ring, horn press, and sp part machining work areas. The controls that have been done are limiting noise sources and workers, rotating working hours, and making rules for the use of ear plugs

The purpose of this research is to determine the potential activities that cause pollution in Situ Jatijajar and Situ Gadog, analyze the water quality and the status of water quality Situ Jatijajar and Situ Gadog. This study uses secondary data on water quality from Situ Jatijajar and Situ Gadog in Depok City, West Java year 2017-2019 from the Environment and Sanitation Office of Depok City. 10 parameters were analysis, pH, COD, BOD, DO, Phosphate, Nitrate, Fecal Coliform, Total Coliform, fatty oil, and detergent. Situ Jatijajar water quality in 2017-2019, pH ranges from 7.16, -7.33, BOD 7.33-9.43 mg/L, COD 15.4-21.1 mg/L, DO 2.44-5.25 mg/L, Phosphate 0.18-0.0043 mg/L, Nitrate 3.02-0.37 mg/L, Fecal Coliform 1600-9200 MPN/100 mL, Total Coliform 160.000-35.000 MPN/100 mL, Fatty Oil 200-300 mg/L and Detergent 45.4-20.7 mg/L. The results of measuring the quality of Situ Gadog water in 2017-2019 for pH parameters 9.55-7.24, BOD 4.29-5.36 mg/L, COD 10.3-12.41 mg/L, DO 3.50 -4.55 mg/L, Phosphate 0.064-0.0055 mg/L, Nitrate 2.76-0.37 mg/L, Fecal Coliform 2200-2400 MPN/100 mL, Total Coliform 2,080-5,400 MPN/100 mL, Fatty Oil 100-400 mg/L and Detergent 35.7-44 mg/L.

Schools are educational facilities that must provide a sense of comfort and calm in learning activities. Noise can interfere with comfort and tranquility in learning activities. The source of school noise comes from traffic and other loud noises. Therefore, this study aims to determine the effect of traffic noise during the COVID-19 pandemic on the school environment of SMA Negeri 70 Jakarta and efforts to reduce noise levels in the school environment. Noise measurements were carried out for 14 days and carried out in the L1-L5 time segment which was carried out for 10 minutes with data reading every 5 seconds using a Sound Level Meter (SLM). The method used in determining the value of the traffic noise level is to measure the time and number of vehicles that pass through the measurement point along Jalan Raya Bulungan. From the results of the research at SMA Negeri 70 Jakarta, the noise level produced during the 14 days of the COVID-19 pandemic at SMA Negeri 70 Jakarta at points 1,2,3,5,7,8,9, and A exceeded the noise level quality standard. KepMenLH No. 48 of 1996 each has a value of 58.12 dBA; 56.18 dBA; 56.77 dBA; 56.55 dBA; 56.17 dBA; 60.10 dBA; 61.23 dBA; and 67.75 dBA. The V/C ratio at SMA Negeri 70 Jakarta shows the highest level of road service is on the 1st Sunday on Saturday, while the level of road service enters the class A category. At point A has the highest noise value of 67.75 dBA because it is located close to with a noise source, namely Jalan Raya Bulungan, while point 7 which is located far from the noise source has a noise level of 56.17 dBA.

Situ Pangarengan is located in Cisalak Village, Sukmajaya District, Depok City, and function as a water catchment area. This study aims to identify activities that caouse pollution and damage, analyze the quality and water quality status, determine the pollutant load capacity and provide recommendations for pollution prevention and control. The main cause of pollution in Situ Pangarengan are from residential and other activities. Parameters BOD, COD and phosphate are exceeded the quality standard. The BOD quality standard is 3 mg/L while the BOD content is 2.33 mg/L-11.83 mg/L. The COD quaiity standard is 25 mg/L, the COD content in water ranges from 9.6 mg/L-48 mg/L. The quality standard for phosphate is 0.03 mg/L while the phosphate content in waters ranges from 1.36 mg/L-2.68 mg/L. The water quality status of Situ Pangarengan is 7.53 (moderately polluted). Pollutant load capacity of BOD is 26,787 kg/year, the existing BOD load is 57,770 kg/year. Integrated effort to prevent and pollution control are developing the potential of Situ Pangarengan as a water conservation and tourism area, structuring the lake landscape, providing understanding to the public about the potential of Situ Pangarengan as a supporting ecosystem for urban sustainability, regular dredging, implementing communal WWTPs and eliminating the entry of garbage into the lake, and maintaining the health of the lake.
