Bioethanol is a renewable and environmentally friendly energy source that can overcome the depletion of oil resources in Indonesia and reduce the increase in greenhouse gases. Organic waste can be one of the raw materials for bioethanol production because of its abundant availability. This research was conducted to determine the potential for organic waste to be processed into bioethanol. This study used vegetable waste, fruit waste, and leaf waste and then fermented using yeast containing Saccharomyces c. The addition of nutrients (urea and NPK) and fermentation time for 3 days, 5 days, and 7 days were carried out to determine the effect on the resulting ethanol content. The production of bioethanol is carried out using the SSF (Simultaneous Saccharification and Fermentation) method so that the hydrolysis and fermentation processes occur simultaneously. The results showed that the highest ethanol content was 18.79% with a fermentation time of 5 days and the addition of 25 gr urea. The addition of nutrients and fermentation time affects the ethanol levels produced.

Water from cattle farming operations that is not properly managed and discharged directly into the environment can cause unpleasant odors and increase the risk of contamination of surrounding water bodies. The purpose of this study was to determine an effective management system in solving odor problems and the risk of contamination of water bodies. The method in this research includes the design of a management system and laboratory-scale processing experiments involving the oxidation pond as the processing unit. The cattle farm liquid waste management system consists of 3 stages, namely pre-treatment, primary treatment, and secondary treatment, where there is a processing unit (oxidation pond) for secondary treatment. Wastewater is treated in the oxidation pond with a variation of the injected oxygen discharge of 6 L / minute, 8 L / minute, and 11 L / minute with residence time during the calculation time according to EPA / 600 / R-11/008 of 2011 (respectively 0.256 days, 0.1356 days, 0.1096 days), 3 days, 7 days, and 14 days were equipped with control of oxidation-reduction potential (ORP) values. The parameters observed were odor, Biochemical Oxygen Demand (BOD) and Total Ammonia (NH3-N). Where the wastewater after the treatment process is yellowish with low turbidity and has no smell. While the test results after the study showed that the average BOD level had met the quality standard. With the highest final BOD level was 152 mg / L and the lowest was 98 mg / L. Meanwhile, the highest total ammonia levels after research were 0.0088 mg / L and the lowest was 0.00032 mg / L.

Penjaringan Sari is one of the urban villages in Surabaya. Based on the explanation from the Surabaya City Health and Garden Office, the most waste generation comes from household waste (residential areas) which reaches 79.19% of the total waste generation. Currently in Surabaya is facing an outbreak of an easily transmitted disease called Covid 19. This has resulted in reduced activities outside the home which automatically increase the number of activities at home. Waste generation in 2017 averaged 0.35 kg / person per day. This research will be compared with previous research to find out how household waste is generated during the Covid 19 pandemic and the composition of household waste in residential areas in Penjaringan Sari Village, Surabaya City. Household waste generation in residential areas, flats, and villages in Penjaringan Sari village during the Covid 19 pandemic amounted to 0.361 kg / person per day, 0.345 kg / person per day, and 0.530 kg / person per day. Which means an increase of 0.09 kg / person per day for residential areas, 0.063 kg / person per day for the apartment area, and 0.044 kg / person per day for the village area. The composition of household waste in the Penjaringan sari village is dominated by compostable waste and the composition of waste that experienced the largest increase was plastic, cloth, glass and metal waste.

Ground Water as an alternative to clean water is often found to contain iron (Fe) and (Mn). The content of Fe and Mn causes a yellow-brown color and leaves a yellow stain on the fabric. Fe content can cause health problems such as nausea when consumed, intestinal wall damage and irritation to the eyes and skin. Meanwhile, Mn content above the quality standard can cause disturbances in the vascular vessels, heart and nervous system. This well water can be treated in several ways, one of which is aeration. Aeration is the process of adding air to water through contact between water and air. There are several types of aerators, one of which is the Tray aerator. The Tray aerator is aerated with a vertical Tray arrangement. The water will pass through the perforated Tray level and will be caught at the bottom. To increase the efficiency of reducing Fe and Mn levels, it can be done by adding Kaolin media and activated carbon. The effect of aeration time is directly proportional to the decrease in Fe and Mn levels. The longer the aeration time, the more significant the decrease in Fe and Mn levels. the contact time between water and gas becomes longer. As a result, the transfer of oxygen from the gas phase to the liquid phase can be maximized. The results of this study indicate that the addition of adsorbent media in Tray aerator variations affects the percent removal of Fe and Mn levels in well water. With the highest percentage removal of Fe was 86.09% with a result of 0.64 mg / l using 500 gr kaolin media for 90 minutes and the highest percentage of Mn removal was 88.70% with a yield of 0.26 mg / l in 90 minute
