Waste is a global problem that is very hard to solve. Waste generation produces leachate that is harmful to the environment. Leachate can seep into the soil causing direct soil and groundwater pollution. Phytoremediation is an effort to use certain plants and their parts to reduce chemical substances in waste and environmental pollution problems. In this study, the plants used were Typha latifolia by varying the number of plants: without plants, four, and five plants. The leachate used comes from the Griyo Mulya landfill, Sidoarjo. The reactor used was 30´30´50 cm and the discharge used was 15 L/day. The reactor used is a continuous system. The parameters analyzed included TDS and NH3. The results showed that the most significant decrease in TDS and NH3 levels was obtained from the reactor of four and five plants with 700 mg/L of TDS and 10.65 mg/L of NH3.

Water covers 70% of the world’s total surface, but only around 3% of it is freshwater that humans may drink and utilize for other purposes. Because of fast growth in many nations, the quality of groundwater is no longer adequate for human consumption. The objective of the study is to assess the groundwater quality of 18 locations in the Ropar wetland in Punjab, India, in different seasons and different source groundwater. When compared to uncontaminated natural groundwater, the groundwater obtained from the test sites had higher pH values. The amount of groundwater pollution is higher in the summer than in the winter. However, there are many challenges face by the groundwater quality research. The groundwater quality in any region of the world is very important towards the survival of human being. Long-term consumption of polluted groundwater with high levels of heavy metals will result in health issues such as difficulty breathing and renal failure.

Although Malaysia has abundant water resources, some parts of Malaysia are currently facing water shortage problems. The increasing demand for water has sparked initiatives to seek alternative water supplies. Rainwater harvesting has been proposed by governments as part of the solution to alleviate the problem of water scarcity. Literature related to rainwater harvesting is available from a variety of sources. In this study, rainfall was analysed as a crucial factor affecting RWHS efficiency, rainwater potential at different zones for residential, industrial, and commercial. In addition, the study evaluated the rainwater quality that obtain fresh rainfall and roof rainfall. Furthermore, potential of treatment technology for rainwater was suggested to optimate rainwater harvesting.

Peningkatan tinggi permukaan laut dapat mengakibatkan intrusi air laut yang berpotensi mencemari kualitas air tanahPencemaran air tanah yang disebutkan terjadi melalui merembesnya air laut yang mengandung kadar klorida (Cl), yang dapat menyebabkan kerusakan pada ekuifer air tawar. Tujuan dilakukan penelitian ini adalah pemanfaatan teknologi biodesalinasi sebagai teknologi yang meyediakan air tawar yang dibantu oleh tanaman mangrove Rhyzopora mucronata dan bakteri (Bacillus mycoides dan Pseudomunas aeruginosa). Penelitian ini dilakukan menggunakan metode eksperimental. Penelitian ini menggunakan 4 reaktor, P0 reaktor kontrol, Reaktor P1 diberi tanaman mangrove (Rhyzopora mucronata) Reaktor P2 diberi tanaman mangrove (Rhyzopora mucronata) dan bakteri (Bacillus mycoides dan Pseudomunas aeroginosa). Reaktor P3 ditambahkan bakteri (Bacillus mycoides dan Pseudomunas aeroginosa). Volume air payau yang digunakan pada tiap reaktor adalah 13 L dan penambahan bakteri 300 ml, pengambilan sampel sebanyak 5 ml dengan 3 kali pengulangan. Hasil analisi setiap reaktor mengalami penurunan. Nilai efesiensi terbesar pada reaktor P2 sebesar 26% dan nilai efektifitas terbesar pada reaktor P2 sebesar 17,81 ⁰/₀₀. Reaktor terbaik dalam menurunkan kadar salinitas air payau adalah reaktor P2. An increase in sea level height can result in seawater intrusion, which has the potential to pollute groundwater quality. The mentioned groundwater pollution occurs through seepage of seawater containing high levels of chloride (Cl), which can cause damage to freshwater aquifers. This research aims to utilize desalination technology as a technology that provides fresh water assisted by the mangrove plant Rhyzopora mucronata and bacteria (Bacillus mycoides and Pseudomonas aeruginosa). This research was conducted using experimental methods. This research used four reactors: P0 was the control reactor, Reactor P1 was given mangrove plants (Rhyzopora mucronata), Reactor P2 was given mangrove plants (Rhyzopora mucronata) and bacteria (Bacillus mycoides and Pseudomunas aeroginosa). The P3 reactor added bacteria (Bacillus mycoides and Pseudomunas aeroginosa). The volume of brackish water used in each reactor was 13 L, and 300 ml of bacteria were added, 5 ml of samples were taken with three repetitions. The analysis results for each reactor decreased. The most significant efficiency value in the P2 reactor was 26%, and the most considerable effectiveness value in the P2 reactor was 17.81 ⁰/₀₀. The best reactor for reducing the salinity levels of salty water is the P2 reactor.

DPI Kabpaten Sidoarjo produces liquid waste from the fish washing process, which has the potential to pollute the environment. The results of the laboratory test of liquid waste produced by DPI Kabupaten Sidoarjo contains 764 mg/L BOD and 1.440 mg/L COD. DPI Kabupaten Sidoarjo uses phytoremediation methods with water hyacinth (Eichornia crassipes) and water spinach (Ipomoea aquatic). The parameters analysed were BOD5, COD, TSS, and TDS and biodegradability ratio. The reactor used was a 25 L batch reactor and the residence time used was 6 days. The results obtained by water hyacinth plants were able to reduce COD and BOD5 levels better than water spinach, namely 98.60% and 98.70%. Then the results of the TDS parameters of the water hyacinth reactor also got the lowest concentration of 368 ppm. For TSS parameters the best value was obtained from the water spinach reactor with a value of 400 mg/L. The pH parameters of the water hyacinth reactor and water spinach got a value between 6-7. The best biodegradability ratio was obtained from the water hyacinth plant reactor, which was 0.5-0.53.

Sidoarjo is one of the largest fish-producing districts in East Java. The high productivity of fisheries is in line with the increasing amount of waste produced. Both solid waste and liquid waste. Generally, liquid waste comes from water used for washing fish, usually brownish, cloudy and smells fishy. In addition, the concentration of organic matter is very high in the waste. The purpose of this study was to determine the reduction in levels of Total Suspended Solid (TSS), Total Dissolved Solid (TDS) and Biocamical Oxigen Demand (BOD) in these wastes using Scirpus grossus. The independent variable used is the variation in the number of plants (without plants, 5 plants and 10 plants). The waste used comes from the Fish Market Depot Kab. Sidoarjo. The research begins with the acclimatization process, then the phytoremediation test is carried out. Based on laboratory analysis, it was found that the best decrease in TSS, TDS and BOD was obtained from the reactor with 10 plants.

Depo Pemasaran Ikan is the largest fish trading place in Sidoarjo Regency. It’s activities produce problems in the form of liquid waste originating from fish washing residue, fish washing waste that is brownish in color, cloudy and has a fishy smell, which has a very high content of organic matter and far so that it can pollute the environment. The purpose of this study was to determine the decrease in the degree of acidity (pH), Chemical Oxygen Demand (COD), and ammonium (NH4-N) in the waste using Scirpus grossus. The independent variable used was the variation in the number of plants (without plants, 5 plants and 10 plants). The waste used comes from the Fish Market Depot, Sidoarjo distric. The study began with the acclimatization process, then phytoremediation tests were carried out. Based on laboratory analysis, it was known that the best change in pH was obtained from a reactor with 10 plants, while the best COD and NH-4N were obtained from a reactor without plants.
