Abstract

The commitment to provide clean water and proper sanitation is one of the goals of the Sustainable Development Programs (SDGs). The government of each region needs to strive for clean water for the community. Efforts to fulfill clean water can be realized with the Water Supply System. Water Supply System sustainability indicators need to fulfill three aspects of quality, quantity, and continuity. The aim of this research is to assess the sustainability of the ‘Sugio’ Water Supply System in Lamongan Regency which serves three villages, namely Sugio, Lebakadi, and Sekarbagus. The aspect of water quality, seen from the results of the analysis of the quality of production water, shows that it meets the quality standards as raw water for drinking water. The aspect of water quantity is calculated to meet water needs for the next 20 years. The calculations results show that the daily average debit requirement is 17 L/s and the daily maximum debit is 19 L/s, while the existing debit is 15 L/s. The aspect of water continuity is calculated from the ability to distribute water during an emergency. The calculation results show that the distribution of clean water when there is no source of electrical energy can only be carried out in a maximum of 1 hour 13 minutes 48 seconds. The conclusion obtained is that the sustainability of the ‘Sugio’ Water Supply System from the aspect of water quantity and continuity still needs to be improved.

Abstract

Tofu industry production activities generate wastewater from soy milk coagulation and moulding processes. The high content of organic compounds in tofu industry wastewater, including COD, requires treatment before discharge into water bodies. The high organic content in this wastewater can be used as a substrate in MFC systems. This research aims to analyse the effect of different anode types in the combination of MFCs-ABR reactors on the power density (mW/m²) and COD removal efficiency of tofu industry wastewater. The research method is quantitative, starting with seeding and acclimatization for 21 days, and then analysing the effect of graphite carbon and stainless steel anodes on the performance of MFCs-ABR reactors with different retention times of 24, 48, 72, 96 hours. The results showed that the graphite carbon anode produced the highest power density of 204.13 mW/m² and COD removal efficiency of 60.42% at a retention time of 96 hours.

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

The wastewater from industrial laundries has a high quantity of contaminants from the washing process, as well as chemical additives. The current study assessed the efficacy of the coagulation/occultation/sedimentation (C/F/S) method to treat laundry wastewater in relation to physicochemical parameters of water quality with the goal of treating this type of wastewater. For this purpose, an experimental design was applied to the C/F/S step using the addition of coagulant Alum, coagulant Alum plus flocculant Superfloc, and coagulant HCA. Alum coagulant has removal efficiency of 52% for COD and 37% for phosphate. The use of alum coagulant and Superfloc flocculant produces COD removal efficiency of 60% and phosphate removal efficiency of 58%. The use of HCA coagulant shows a removal efficiency of 64% for COD and 78% for phosphate. This shows that using more HCA coagulant is more effective than using alum coagulant and Superfloc flocculant in laundry wastewater treatment.

Abstract

Electricity is a vital aspect of modern infrastructure that supports various human activities. Therefore, the increasing need for electrical energy requires good planning to ensure the availability of electrical energy in the future. The transmission system, especially the Medium Voltage Cable Line (MVCL), plays an important role in distributing electrical energy from generators to consumers. However, MVCL construction involves high-risk work, so it requires special attention to occupational health and safety (OHS). This research uses the HIRARC (Hazard Identification, Risk Assessment, and Risk Control) method to identify and control risks in MVCL construction projects. It is hoped that the results of this research can provide recommendations for improving occupational safety and health as well as efficiency in future MVCL construction projects.

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.
