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. "Applying Technology to Solve Water Shortage Photolysis Clean countryside" in Sendang Village Penanggungan District of Trawas Mojokerto, done in KKN PPM activities. KKN PPM was a joint activity between students, villagers, lecturers and youth in the village. The application of photolysis technology can benefit the surrounding community

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

Wastewater produced by untreated restaurants can increase the COD, BOD, TSS, and grease in water content. Household wastewater treatment only uses a grease trap, so it does not meet the quality standards requirement. For this reason, a unit performance evaluation is required. One technology that can improve wastewater quality from grease trap treated wastewater uses a biological process called Sequencing Batch Reactor (SBR). This research is about processing the output of grease trap waste from Padang restaurants using the Sequencing Batch Reactor Continuous Flow unit. C ontinuous influent flow reactor is used in this research. The processed sequentially but discarded intermittently. This study aims to determine the performance of SBR-CF in reducing the content of COD, TSS, Total N, and PO4. SBR-CF was operated with hydraulic retention time (HRT), and the aeration rate varied, which were 12, 24, 36, and 48 hours and aeration rates of 7 L/min and 14 L/min. The results showed that the optimum HRT and aeration rates were 24 hours and 14 L / minute. With the efficiency of removal of COD, TSS, Total N, and PO4 produced respectively 96.9%; 98.63%; 86.72%; and 55,6%
