Abstract

Reservoirs are commonly used for aquaculture with floating net cage systems. The fish feed is not all eaten by the fish, so it is wasted to the bottom of the reservoir as uneaten feed. The organic content in the feed and the possibility of anaerobic conditions at the bottom of the reservoir waters can generate the decomposition process, which produces methane gas which is also a greenhouse gas. The floating net cages in the Sutami Reservoir, Indonesia, are about 173 ha in width, with the fish feed requirement of around 77.97 kg ha-1 day-1. Estimated uneaten feed and wasted to the bottom of the waters is about 2.3 g m-2 day-1, and methane gas emission from the feed waste is about 0.9 g m-2 day-1. This methane gas can contribute to methane gas in the atmosphere, so it is necessary to manage aquaculture, which has the potential to contribute methane gas as a greenhouse gas. Application of double nets on floating net cages can develop to attempt the reduction of feed waste in the fish farming system.

Abstract

Sounds that are not desired by the listener, where the sound can distract, interfere with activities, or cause danger during daily activities, can be called noise. Noise at a certain level originating from the sound of work tools in the production process can cause comfort and health to be disturbed. The lousy impact that often occurs if a person is exposed to noise for too long is the effect on hearing, which can cause deafness, but this can be controlled by using hearing protection equipment that will determine the amount of compensation value to be received by the surrounding community. The existence of the Landfill, which is often located in the middle of community settlements, has a direct impact, one of which is noise during every working hour of the Landfill's operations. One example of a Landfill that is still active today is the Klotok Landfill which is located in Pojok District, Kediri City. In this research, noise mapping was carried out to determine the pattern of noise distribution that occurs in the work environment. Making a noise contour map due to these activities will use a software called Surfer, which is a simple program to generate noise curves (noise contours) spatially the location of potentially hazardous areas. The result shows that activities at the Klotok Landfill have noise values ??ranging from 40 to 92 dB. The highest noise is in the location around landfill area 3, which is actively operating. The high noise level also can be found in the weighbridge, which is a place for transporting vehicles to pass. Evaluations at points 17, 18, and 19 indicated the need for protective wear, such as earmuffs or setting a break every 1.4, 3.6, and 2.2 hours for area workers.

Abstract

Sanitary landfill is the most common type of waste processing in Indonesia because it can minimize the negative impacts caused by waste and can utilize methane gas produced from the waste decomposition process. An analysis of the population projections of Kediri and waste generation was carried out to determine the waste generation at the Klotok Landfill. This study predicts methane gas emissions produced at the Klotok Landfill based on the IPCC method. This study uses two types of data: secondary and primary data. Secondary data includes the number of residents and waste entering the landfill, while the primary data used is waste composition. A sanitary landfill is needed in order to minimize the negative impact of solid waste, one of the negative impacts caused by solid waste is the formation of methane gas.  This study uses the IPCC (Intergovernmental Panel Climate Change) model to calculate methane generation in the next ten years. The results show that population significantly impacts CH4 emissions from solid waste disposal facilities. Due to the city's growing urbanization and population increase, the production of waste in Kediri is increasing. Total waste production in 2032 is 723.98 m3/day or 217,195.44 Kg/day. In contrast, the total percentage of waste that goes to the Landfill is around 55%, so the waste that goes to the landfill is around 398.19 m3/day or 119.457.49 kg/day. In addition, the increase in the amount of solid waste at the Klotok landfill also produces methane gas. Based on the amount of waste that goes to the landfill, the projected methane gas formation from the IPCC model in 2032 can reach 6.148 Mg in a day.

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

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.
