Abstract

Slaughterhouse wastes generally contain blood, proteins, fats, and suspended solids that cause a high load of organic matter which can pollute rivers and water body. The waste water of slaughter house will cause changes on the quality of the water, such as increased colour, pH, total dissolved solids, suspended solids, fats, BOD5, ammonium, nitrogen and phosphor. In this study aims to reduce the content of slaughterhouse waste water, using Rotating Biological Contactor (RBC) modified with a sludge zone.  It was expected that by modifying the sludge zone, the efficiency of RBC performance can be further improved. This study used a variety of Hydraulic Retention Time (HRT) of 2.8 hours, 3.5 hours and 4.2 hours along with waste water dilution of 50%, 75% and 100% using the continue system into clarifier process. Based on the results of the study, the decreased percentage in COD concentration reached 86.68%, the total decreased percentage of Nitrogen concentration reached 66.11% and the decreased percentage in TSS concentration reached 71.87%. The pH value is neutral with a range of 7.6-8.3 with temperatures range of 26oC-30oC during operation. The highest DO values reached 5.2 mg/L with a range of organic surface loading values of 89.77 - 135.45 grams BOD/m2.day. The organic load figure exceeds the RBC organic load standard which averages around 8-20 grams/BOD/m2.day. The increased of organic load, indicates that RBC with modified sludge zone was able to treat wastewater with high organic load, such as slaughterhouse waste water

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

Vegetables that do not sell and rotten will be thrown away. This makes the volume of waste increases every day. Vegetable waste that is no longer being sold, could reprocessed into useful products and selling value. The purpose of this research is to use vegetable waste to become bioethanol raw material, which have economic value. The selected vegetable waste was from potatoes, carrots, cabbage, cassava, chicory, and green mustard, because they have higher carbohydrate content than other vegetable waste. The bioethanol product produced will be measured by its bioethanol content and fermentation time. These two factors, affect the quality of the bioethanol produced. The microorganism used in this study was Saccharomyces cerevisiae. These microorganisms are in bread yeast and tape yeast, which are also examined for their effectiveness in the production of this vegetable waste bioethanol. From this study, producing bioethanol with the highest ethanol content of 15% v / v, produced in the interaction of bread yeast and 6 days’ fermentation time. Meanwhile, from the production using yeast tape, obtained ethanol levels of 13% v / v. Bioethanol from vegetable waste is not only to reduce the burden of waste generation, but can be used as an alternative energy to replace fuel.

Abstract

Air is the most important element for life. However, the air we breathe now tends to be dirty and not good for health. Air pollution occurs due to transportation activities. Cigarette filter manufacturers produce cigarette filters that are not suitable for use because they do not meet standards. This research utilizes an unused cigarette filter which can only become waste that was difficult to decompose by nature. This study aimed to assess the ability of unused cigarette filters to reduce gas emissions, carbon monoxide (CO), and hydrogen carbon (HC). This unused cigarette filter, known as an adsorbent, was made of highly absorbed cellulose acetate. These cigarette filter adsorbent has been studied on motorcycle exhausts since the 2000s. By modifying the type of cigarette filter, namely the ordinary cigarette filter in which carbon is added. The results showed that the unused cigarette filter was able to become an adsorbent for pollutants in the air, especially CO and HC. The type of cigarette filter that uses additional carbon has been shown to reduce CO and HC concentrations by 60% and 57.5%, respectively, than conventional cigarette filters.

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%
