Air has an important meaning in the life of living things and the existence of other things, so it must be protected for human life and other living things. The utilization must be done by maintaining air quality from air pollution. Indoor air quality is also a problem that needs to get attention because indoor air pollution was larger than the outdoors, which affects human health. As for how to reduce indoor air pollution by utilizing plants, other than as an ornamental plant, some plants can also function as pollutant cleaners. One of them is like the plant used in this research that is Sirih Gading (Epipremnum Aureum). The purpose of this study is to determine the ability of Sirih Gading plants (Epipremnum Aureum) in absorbing indoor air pollutants. The method used are SNI 7119.10: 2011, SNI 16-7058-2004 and NIOSH 1501: 2003. The results obtained are the Sirih Gading plants (Epipremnum Aureum) capable of absorbing carbon monoxide and benzene pollutants but not so much affect the dust particles

The growth of the laundry industry in urban areas increasingly increases the level of pollution of urban water bodies by detergent waste so that water is increasingly polluted. One of the compounds contained in detergent is a phosphate compound which can cause eutrophication in water bodies. Phytoremediation is an attempt to use plants and their parts to decontaminate waste and environmental pollution problems. Eceng gondok (Eichhornia crassipes) and Kiambang (Salvania natans) is one of the water plants that can be used to reduce pollutant levels in industrial washing clothes waste by phytoremediation. This study aims to determine the ability of water hyacinth (Eichhornia crassipes) and kiambang (Salvania natans) in reducing phosphate in clothes washing waste by using two variables, namely the number of plants 2, 4 and 6 plants as well as contact time 2, 4 and 6 days. The results showed that the most optimum plants reduced phosphate levels, namely water hyacinth plants (Eichhornia crassipes) with 2 plants and 4 days contact time with a phosphate concentration of 0.3389 mg / L

ncreasing the amount of domestic waste water which is not balanced by the increase in receiving water bodies both in terms of capacity and quality, causes the amount of waste water entering the water body to exceed the carrying capacity and carrying capacity. Then domestic wastewater in the residential environment for the future has the potential to become a fairly serious threat to pollution of the aquatic environment. Based on the results of the study it was found that the percentage of pollutant levels decreased against expotentially tested parameters with the incubation period. The greatest effectiveness occurred at the incubation time on the second day, decreasing detergent content from 34.88 mg / L to 8.10 mg / L with the reactor effectiveness value of 76.78%. COD levels decreased from 310.77 mg / L to 60.37 mg / L with a reactor effectiveness value of 80.57%. BOD levels decreased from 282.55 mg / L to 50.32 mg / L with a reactor effectiveness value of 82.19% and a decrease in ammonia content from 157.77 mg / L which was 53.81 mg / L with a reactor effectiveness value of 65.89%.

Water is the most important requirement for living things. Humans and other living things are very dependent on water to sustain their lives. Based on the results of external supervision carried out by the District Health Office. Tangerang in 2016 found the quality of clean water at Kelapa Dua Health Center containing Mn and Fe with levels that exceeded the quality standard. Based on Permenkes 416 of 1990, Manganese (Mn) levels in permissible drinking water is 0.5 mg / lt, Iron (Fe) 1.0 mg / lt, In this Data Analysis Technique including data processing techniques carried out by linear regression of data set as research variables. Based on the results, the following conclusions are obtained, Efficiency of activated carbon media with a media thickness of 90 cm in reducing Fe content in water by 39.38%, Efficiency of activated carbon media with a media thickness of 90 cm in reducing Mn content in water by 81.82%. There is a Significant Effect of Filtration Treatment on Fe, and Mn Content. The thicker the filtration media, the better degradation of Fe, and Mn.

Tempe industry is one type of industry that produces liquid waste which can cause pollution if it is not managed properly because it contains high enough organic compounds, to overcome these problems then the idea arises to utilize tempe liquid waste to become a useful final product by managing it. as organic liquid fertilizer which is useful for fertilizing plants. This study aims to determine the pH, nitrogen and total bacterial content of tempe wastewater fermentation in this study. In this study there were two treatments, namely the processing of tempe liquid waste without bacteria (blank), the processing of liquid tempeh with the addition of the bacterium Pseudomonas sp. Analysis of fertilizer quality parameters such as pH, nitrogen and totalbacteria.
