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

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

A magnesium oxide and titanium (II) oxide nanocomposite, MgO/TiO2 was synthesized to improve its surface area thus its adsorption capability may be risen. The synthesis was applying sol-gel method, combining MgO and TiO2 nanoparticles with NaOH becomes a nanocomposite with higher surface area. The pH effect on adsorption were analyzed. The expectation of using MgO/TiO2 compared with TiO2 and MgO alone is it may react faster on an adsorption trial with remazol turquoise blue dye, and the TiO2 may give its photocatalysis ability to the synthesized material. Less acid the condition of the solution, the capability of the MgO/TiO2 catalyst on adsorbing the remazol turquoise blue dye will increasing. After 90 minutes, the photocatalysis rate surpass the adsorption rate and reach equilibrium.

Abstract

High noise levels resulting from the fabrication process of the BMPP 60 MW bollard projectrequire control measures to reduce noise intensity and ensure that all workers are not exposed to work-related health issues due to noise exposure effects. The aim of this study is to measure the noise levels generated by activities in construction workshop plat 2 and conduct noise mapping. The research method employed is noise mapping using Surfer 16 software to create noise contours. Noise measurements were taken at 52 points within construction workshop plat 2 using a multifunction environment meter 5 in 1, and the allowed work time was calculated based on the NIOSH method. The research results indicate that at points 29, 30, 31, 32, 45, 46, 47, 48 located in the grinding and welding area, the noise level exceeds 85 dB. Therefore, if no control measures are implemented, based on the calculated ideal working times for each point in sequence, they are 6.1 hours, 5.7 hours, 5.4 hours, 5.5 hours, 6.6 hours, 6.8 hours, 6.2 hours, and 6.5 hours, respectively. The conclusion of this study is that out of the 8 points exceeding 85 dB according to the Threshold Limit Value (TLV) based on the Kemenaker Number 5 of 2018 so that control is needed in the form of installing noise safety signs and use of earplugs.

Abstract

Black Soldier Fly (BSF) larvae are one type of insect that has the potential to help reduce organic waste because they can act as decomposers by converting organic waste biomass into high-quality protein. In their utilization, adult BSF larvae are often used as a component in fish and livestock feed, and the leftover maggots can be utilized as a substitute material for NPK fertilizers. The nutrient content and quality of adult BSF larvae, however, depend on the treatment received during their development, including their feeding media. This study aims to investigate the effect of different feeding media on the protein content of BSF larvae, with the goal of identifying the best treatment for BSF cultivation. The review is conducted by analyzing data from literature related to maggot feed and its nutrient content. The highest protein content, based on the collected data, is found in BSF larvae fed with a combination of 30% leftover food and 70% fruit waste, with a protein percentage of 59.25%.

Abstract

The waste piles in the landfill pose a higher environmental hazard compared to the waste at its source due to the potential formation of leachate and air emissions. Consequently, waste management from the source is essential to minimize the amount of waste in the landfill. The waste management methods at each location typically vary based on the composition, characteristics, and quantity of waste present in that specific area. In this study, an analysis of waste piles at facility X was conducted through the process of sorting and weighing the waste during October 2023, with the objective of providing research findings that can be utilized to determine suitable waste management options for the location. The research revealed that the dominating composition of the waste consists of organic waste, with garden waste accounting for 55.95% and food residue comprising 10.75%. Composting was selected as the recommended alternative for waste treatment in the area. Garden waste, primarily composed of dry leaves, is suggested to be treated using the pile composting method, while food residue is suggested to be treated through a combination of Black Soldier Fly larvae biotechnology and Takakura composting.
