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

Hospital hazardous waste (B3) management is crucial to avoid negative impacts on health and the environment. This community engagement aimed to improve B3 waste handling capacity in a regional hospital in East Java. Activities included site observation, technical discussions, SOP development, labeling training, and digital reporting via the Festronik system. Observations revealed issues in waste labeling, characterization, and logbook documentation. Interventions successfully improved labeling according to waste properties, developed technical SOPs, and fulfilled storage requirements based on Government Regulation No. 22 of 2021 Article 419 paragraph (4). Enhancements such as emergency response tools and updated signage further supported safe and compliant waste management. This program is expected to strengthen sustainable B3 waste governance in the healthcare sector.
