Abstract

A research to model particulate emission was conducted in the plywood industry in Kendalrejo, Talun, Blitar Regency, East Java at an altitude of 273 masl. The industry already has an environmental pollution control unit, with an outlet through a chimney emitting an average emission of 0.14 g/s. The model simulation was carried out using AERMOD View software with data on wind direction and speed, solar radiation, temperature, clouds, and air pressure. The results show that the presence of the wood industry in Talun, Blitar Regency will have an impact on particulate emissions to areas in the east, southeast, west, and south, as the dominant wind direction. Dispersion modeling of particulate pollution with current conditions has resulted in dispersion with concentrations below the allowable limit in PP 22 of 2021. Modeling with several scenarios shows that the dispersion pattern can be maximized by increasing the chimney emission rate to 18 m/s, to minimize turbulence around the chimney and accelerate the reduction of particulate concentrations. Increasing the height of the chimney or increasing the diameter of the chimney will also affect the decrease in concentration in all directions so it becomes a recommendation that should be considered by the industry.

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 amount of domestic wastewater without prior treatment is discharged into water bodies so that it is felt that the quality is decreasing day by day. Organic content and microorganisms are a concern in terms of quality. The high content of organic and microorganisms such as Total coliform. Decreasing these parameters is the main goal in this study. In the aerobic process, organic processing uses an air supply of 20 L/min in suspended and attached treatment for attached media using K5 caldnes media and spiked bioball, each of which is 30% of the reactor volume, preceded by the seeding and acclimatization process. Variations in processing time used were suspended for 2 hours and attached for 6 hours and vice versa. Furthermore, it is processed by simultaneous physical processing, namely the process of deposition and sterilization with exposure and deposition times of 2 to 6 hours. Based on the results of the study showed that seeding and acclimatization were carried out for 21 days. The best processing was obtained using suspension for 2 hours, attached for 6 hours on kaldnes K5 media and precipitation as well as exposure to ultraviolet light for 6 hours showed a decrease in COD of 92.85% and for Total coliforms of 98.67%.

Abstract

Klotok landfill is a final waste processing site in the City of Kediri that has been operating since 1992 to manage waste in the Kediri City and its surroundings. Waste management activities at the Klotok TPA generate emissions from the waste pile and heavy equipment activities. This study aims to determine the air quality at the Klotok Landfill through direct measurements to obtain results with a more accurate approach. The measurement results will then be modeled with AERMOD software to determine the distribution of these pollutants to the area around the TPA. In this study, air quality measurements were carried out at three points in the Klotok TPA to determine the level of pollution that occurred. Air quality is measured directly using a High Volume Air Sampler (HVAS), Impinger, and Sound Level Meter. Air pollutant parameters measured included Nitrogen Dioxide (NO2), Total Suspended Particulate (TSP), Sulfur Dioxide (SO2), Oxidants (O3), Carbon Monoxide (CO), Lead (Pb), Non-Methane Hydrocarbons (NMHC), Particulate Matter 2.5 (PM2.5), PM10, Ammonia (NH3), and noise. The measurement results show that the CO parameter exceeds theambient air quality standards of PP No. 22 Year 2021 at the weighbridge and the landfill 3 with values of 13,750 and 18,750 µg/Nm3 respectively,while other parameters still meet the quality standard. The model with AERMOD software shows the dispersion of CO nearby the landfill area occurs quickly so that since the first 100 meters the CO concentration has been dispersed to below 10 µg/Nm3. CO concentrations at a distance of more than 1 km from the Klotok TPA are generally below 1 µg/Nm3.

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 provide 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 was to assess the sustainability of the ‘Sugio’ Water Supply System in Lamongan Regency, which served 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, met the quality standards for drinking water. The aspect of water quantity was calculated to meet water needs for the next 20 years. The calculation showed that the daily average debit requirement was 17 L/s and the daily maximum debit was 19 L/s, while the existing debit was 15 L/s. The aspect of water continuity was calculated by the ability to distribute water during an emergency. The calculation showed that the distribution of clean water when there was no source of electrical energy could only be carried out in a maximum of 1 hour, 13 minutes, and 48 seconds. The conclusion obtained was that the sustainability of the ‘Sugio’ Water Supply System from the perspective of water quantity and continuity needed to be improved.
