The problem that is often found in well water is the high content of iron (Fe). This study aims to reduce the content of Fe in water well with aeration and adsorbtion systems. Aeration used is a cascade aerator using two wide variety of cascade which the height of each steps are 20 cm. zeolite sand with a diameter 8 mesh.. The sample was taken at one of the community wells in the Sukodino area of Sidoarjo. The study was conducted for three days with a processed sampling system carried out on the aerator output and both adsorbtion. The results showed that the aeration process with cascade aerator was able to reduce Fe levels up to 61,93 % and 74.58%. While the adsorbtion process with zeolite media can reduce Fe levels by 86,12% and 96.81%.

Currently, the industry in the field of batik production is one that has the potential to be developed. In the process, the batik industry produces liquid waste that reaches 80% of the total amount of water required. The waste produced will be a problem for the environment. The waste generated from the batik industry will be a problem for the environment. Batik industrial wastewater treatment can be carried out by means of biological treatment because it can reduce the organic content in batik wastewater. One of the effective and efficient waste treatment technologies is Sequencing Batch Reactor (SBR). The operating principle is filling and interesting SBR(fillanddraw),which consists of five stages: charging(fill), the reaction(reaction), precipitation(settle),d isposal of treated water(decand) and sludge disposal (idle).This study aims to determine the performance of SBR with the addition of green adsorbent in reducing the BOD, TSS and color content of batik wastewater. SBR was operated with a hydraulic retention time (HRT) and varying waste concentrations, namely 36 and 48 hours respectively and waste concentrations of 50% and 100% with the addition of coconut shell activated carbon, bamboo charcoal, and zeolite. This research was conducted with a process pre-treatment, namely coagulation and flocculation which will optimize the batik industrial waste treatment process. The results of this study indicate that activated carbon can describe parameters according to quality standards, especially coconut shells, which can reduce COD by 98.27%.

ABSTRACT The increase in laundry activity in the city of Surabaya has led to an increase in the use of detergents, where the content in detergents has a bad effect on the environment. This study uses an adsorption method with commercial activated carbon upflow flow with flow variations of 5 ml / minute, 10 ml / minute, and 15 ml / minute with a height variation of 10 cm, 15 cm, and 20 cm and a sampling time of 2 hours, 4 hours, 6 hours, 8 hours, 10 hours and 12 hours. The results obtained were the highest efficiency from phosphate removal of 99.07% and anionic surfactant (detergent) 95.35%. The optimum discharge is 5 ml / minute with a height of 15 cm of phosphate and 20 cm of anionic surfactant (detergent). The suitable model is freunlidch, where the R2 value is 0.9418.

Almost in every city in Indonesia there are many home-scale tempe industries. These industries have not yet treated their waste, which has resulted in river water pollution. Limited funding becomes an obstacle when industrial owners build wastewater treatment facilities. The construction of an appropriate and cheap wastewater treatment facility will be of great benefit to them. The combination of an aerobic reactor and biofilter media is a biological waste water treatment process using filter media. This study used an aerobic system with the variations used were detention time for 24, 48, 72, 96, 120 hours and a combination of a consortium of microorganisms. The parameters analyzed were BOD, TSS, and TDS. From the research, it was found that the optimal removal efficiency with a consortium of microorganisms in reactor A with a residence time of 120 hours and the final results were BOD 95.58%, TSS 24.82%, and TDS 48.95%.

ABSTRACT Panyuran beach is a very famous tourist destination in the Tuban area is an average number of tourists in the last 3 months, from August to October 2020, is 25,199 people. The research time had been carried out for 14 days in the Panyuran beach.tourism area using the data collection method, namely the Simple Random Sampling method. The results obtained are 400 kg of total waste generation and divided into 25 kg of paper waste, 66 kg of organic waste, 10 kg of non-organic waste, and 299 kg of plastic waste. For plastic waste that is suitable for recycling, which is 299 kg, and the remaining 101 kg is waste other than plastic waste which will be forwarded to the TPS.

Biogas is a flammable gas produced from the fermentation process of organic materials by anaerobic bacteria. These compounds in the digester will be converted into methane compounds which can be burned as an energy source. These materials are cow dung, hydrilla verticillata plants, water hyacinth plants, and elephant grass plants. In this research, we try to use combination materials between cow manure with variations of the three plants with a ratio of 2: 1 and a combination of plant variations with a ratio of 1: 1. To compare the 3 plants which produce biogas optimally. The parameters analyzed consisted of water content, C / N ratio, temperature, pressure, flame duration and methane gas content. The results showed that the best biogas was obtained during fermentation for 30 days in a mixture of cow dung and hydrilla verticillata at a ratio of 2: 1 with a moisture content of 41.3%, a C / N ratio of 21.5%, 50.4%. methane gas levels. And marked by an increase in temperature reaching 35oC also with the longest flame, which is for 72 seconds using a portable stove

The tofu Industries was established for food industries who has a positive and negative impacts for environment. Negative effect from tofu industries was a waste that caused impact for environment. Environment pollutions appears from a solid waste (tofu residue) and waste water. Most of all waste water who caused from tofu industries is a thick liquid separated from tofu blocks called “whey”. Waste from tofu industries had a high organic content such as COD and TSS. In this research, several method were used for reduce the organic content. Coagulation with Aluminium sulfate (Al2(SO4)3, could reduce a Chemical Oxygen Demand (COD) content until 50,3% and Total Suspended Solid (TSS) until 81% with doze of coagulant 1000 mg/l. Fotocatalyst TiO2 could reduce Chemical Oxygen Demand (COD) 50% with an exposure time 150 minutes.

ABSTRACT Laundry wastewater is one of kind waste in general disposed directly into the environment (sewage) without any treatment. Laundry wastewater contains pollutants including Surfactants, Phosphates, BOD and TSS. Phytoremediation is one of the methods used in laundry wastewater treatment and was tested in this research. The plants used in this method are Mensiang and Lembang. In addition, this research uses a batch system with volume 10 liters and the variation of space between plants are 3 and 5 plants per reactor. The detention time of wastewater in the reactor is 3, 6, and 9 days. The results from this research are percents removal of Surfactant and BOD was 97,26% and 84,94% and it happened on Lembang reactors. Percents removal of Phosphate and TSS was 98,38% and 93,81%, and it happened on Mensiang reactors. The optimum time detention are 9 days.

Along with the increase in population and consumption pattern, they cause increase in waste volume, types, and characteristics. All this time, most of the society consider waste as unworthy leftovers and useless. At this study location, Panarung Sub District RW XIV, has limitation in waste treatment because facilities provided are not adequate and lack of awareness from the community. Dominating wastes in this study location are organic wastes such as food waste and leaves, plastic, and paper wastes as well. Aims of this study are to find out waste treatment activity’s driving factors, and community’s awareness towards the environment’s quality at Kelurahan Panarung RW XIV. Datas obtained from this study will be given in form of tables, charts, and will be analyzed through Minitab Software for correlation analysis. This study has been conducted for 14 days at Panarung Sub District RW XIV, and it is known that local communities do waste sorting and recycling. The results obtained are, waste generation before being sorted is 303,5 kg and after being sorted it is reduced to 185,55 kg. From the sorting activity, it is known that the mean of waste generation reduction is 38,86%.
