Abstract

Sendang was a village of Subdistrict Penanggungan Trawas Mojokerto, that has ground water source. However, with its rapidly increasing population growth, it made bad impact for the quality of water resources. Disposal of garbage and animal husbandry activities that were above the water source, has a contribution as a polluter of water resources. Escherichia coli was an important parameter as an indication of contamination of ground water or potable water. By providing knowledge and technology for the people of Sendang, helped them to get ground water. Photolysis technology applied in Sendang was a disinfection technology. The process kills bacteria by using ultra violet light. The energy used to power the ultra violet light is derived from solar energy. Solar Cell used to capture solar energy which is then stored into the dry battery (batteries) to provide energy in ultra violet light. So the villagers are not burdened by the cost of electricity for this technology. Disinfectant process by using photolysis technology could removal E. coli bacteria till 75 % for 80 minutes. Removal of E. coli increased by exposure of Ultra violet on long time.

Abstract

Electrocoagulation is an electrolysis process with the aimed of destabilizing suspensions, emulsions, and solutions containing contaminants. The process was to connect the direct current (DC) through the water to become flok that it was easily separated. This electrocoagulation process required an electrolyte solution and an electrode. Batik wastewater was used as an electrolyte solution and Aluminium as the electrode. The mechanism of the coagulation process for reducing organic suspension was, on an electrolyte in this case was batik wastewater placed two Aluminium electrodes (cathode and anode) and connect it to the direct current, so it’s called electrochemical process. This research aimed to treat wastewater batik by using electrocoagulation process in eliminating of suspended organic. This was due to the fact that wastewater was generally alkaline and has high organic matter and high suspended solids. Suspended solid produced in the process of preparation. Based on the electrocoagulation process, the treatment variables in this research are, variations of current strength are 1, 2, 3, 4 and 5 Ampere and contact time are 60,90,120,150 and 180 minutes. While other influential factors were as a fixed variable. The specified variables were the thickness of the plate and the distance between the plate, the temperature according to the ambient temperature.

Abstract

Management and processing of organic solid waste are simpler than inorganic solid waste. Organic solid waste was more easily decomposed if it was disposed of or buried in the soil. There was no area for the community to be heaped up the organic solid waste. Moreover, the water level is relatively shallow, making it possible for organic waste to mix with groundwater. Corn cobs were an organic solid waste that was mostly produced by the seller of roasted corn or boiled corn on the side of the road. This corncob waste has a contribution to the increase in rubbish in solid waste disposal. For this reason, the use of corn cobs was necessary. This corncob waste can be used as handicrafts to replace handicrafts made from plastic. The community, especially housewives, has the potential to innovate in making handicrafts. It's just that it requires supportive technology for creativity. The results of this community service activity were several handicrafts made from corn cobs that have been processed and added with glycerol as a plasticizer. The method of reusing corncob waste into handicrafts has contributed to reducing corncob waste by corn sellers on the roadside. This community service activity in addition to increasing the creativity of housewives, also indirectly reduces the corn cobs heap in solid waste disposal.

Abstract

The abundance of microplastics in Surabaya's surface water can disrupt the sustainability of river ecosystems and harm humans because most of the raw water used by the people of Surabaya comes from surface water. Microplastics less than 5µm in size contain harmful chemicals such as Polychlorinated Biphenyls (PCBs) and are toxic. One alternative treatment is to reduce the levels of microplastics in the electrocoagulation process. Electrocoagulation is the process of clotting and deposition of fine particles in water using electrical energy. Microplastics contained in the water are removed through flocculation and deposition processes. This study aims to determine the effectiveness of the electrocoagulation process on reducing microplastic levels. The variables of this experiment are the distance of the electrodes (1.5 cm, 2 cm; 3 cm, and 5 cm), and the detention time (15 minutes, 25 minutes, 30 minutes, 45 minutes). This research was set up by using a reactor with a volume of 5 liters and a settling time of 30 minutes.

Abstract

Tofu industry produces the waste that contains a lot of organic substances. The waste is discharged into the environment without any treatment process, it will cause the environmental pollution. In Indonesia, tofu industries (the small-scale industry) mostly do not treat their waste due to the problem of the high cost treatment process. The purpose of this research is to know the effective and economically reasonable that can be used by tofu producers to process tofu waste, especially liquid waste so not damage the environment. Water treatment process using bacterial from waste water as medium seems promising to develop since it does need any bacteria starter or other media like glucose. The other reason is wastewater from food processing is more suitable for microorganism cultivation because its effluent contains significant beneficial nutrient and less of toxic compounds and harmful substances that interface with the growth of microorganism in same condition (pH and Temperature) in Acclimatization process can reach 83.2% after 7 days of treatment. After the detention time (18 hours) the results of COD number also greatly decrease with 2.5 hours recirculation at 12 L/min air and pH 3.7 and 4.5 it can reach 85% and 86% of removal COD.

Abstract

Fish processing waste management in the coastal area of ??Kenjeran Beach is very critical to the environment. The production process of smoked fish has also created various solid wastes in the form of offal, head, tail, and fish fins. In this case, the solid wastes produced were disposed of without any prior management thus it can cause environmental pollution to reduce the pollution, it is necessary to utilize it to minimize the pollution. Bulak Fish Center Surabaya has plenty of smoked fish retailers selling their catches. Waste management has not been carried out optimally because it was relatively expensive for retail scale traders, so there needs to be an alternative utilization of fish waste. Wastes generated from smoked fish have great potential to be used as raw material for fish feeds with a fairly high content of protein and lipids. In addition to protein and amino acid sources, fish waste also contains minerals and vitamins. Utilization of smoked fish waste such as innards in the form of digestive organs, heads, and tails of these fish can be used as fish pellets raw material. The knowledge about waste and how to utilize the waste as fish feed needs to be informed to the fish processing business owners and the community around the Bulak Fish Center Surabaya. This community service will provide basic knowledge, and counseling, and become a pioneer of fish feed production so that it can be applied as fish feed materials used for fish cultivation.

Abstract

The problem of domestic wastewater originating from restaurants is the largest contributor to organic wastewater in urban waters. Among them are waste water parameters, namely oil, and grease. Oils and grease are compounds that do not dissolve easily in water. However, it can be dissolved with non-polar organic solvents. The carbon chains of oils and grease are also long. So, it is difficult to decompose and takes a long time if processing uses the help of microorganisms. So, the alternative is to use physical-chemical processing. In this research, we tried using a static mixer and an impeller mixer. We conducted a systematic review of DAF techniques in wastewater treatment. We reviewed six indexed databases namely dissolved air flotation, microbubbles, wastewater treatment, and key operational and design parameters involved in the effectiveness of the flotation process. In this pre-treatment, the focus is on the withdrawal/discharge speed in collecting wastewater as a test and the effectiveness of mixing wastewater with coagulants and air pressure. These three aspects are used in equilibrium to achieve the optimum dose for the static mixer use scheme. Meanwhile, the impeller mixer scheme uses rotational speed in mixing with the coagulant, contact time, and Reynolds number to achieve the required turbulence. Apart from that, the use of electrical energy in the pump is also calculated in these two schemes. The results obtained were the amount of weight of oil and grease collected in the static mixer pretreatment of 9.12% w/v and the impeller mixer of 7.63% w/v and the results of the organic content of the Chemical Oxygen Demand (COD) parameter for the static mixer were 86.92 % and mixer impeller 78.86 %. From these results, static mixers have advantages over using impeller mixers in terms of the effectiveness of the oil and grease reduction process.

Abstract

Universitas Pembangunan Nasional “Veteran” Jawa Timur is one of the public facilities that produces solid waste, including organic waste, inorganic, and hazardous waste. Waste that can be immediately utilized is organic waste consisting of food waste and leaves and twigs. Therefore, appropriate technology is needed to process organic waste into more useful goods and as a better management alternative through community service. One of the alternatives for processing waste is recycling it into compost using Simultaneous Composting Technology with EM4 and MOL. The main target of this community service is to reduce waste and utilize university waste with appropriate technology for regional coverage and national coverage in the future. The method of this community service is to separate waste between organic and non-organic, selected organic waste is cut by a hammer mill, and then other waste from the canteen activity is made Local Microorganisms (MOLs) as the decaying medium in the composite production of the organic garbage processing device reactor. As a result, this community service has been running smoothly and well. The results of this community service have a positive impact through the use of organic waste into compost which can be utilized by the internal campus and generate economic value.
