Suatu keadaan dimana kualitas udara menurun dan terkontaminasi zat, apabila zat tersebut berbahaya maupun tidak yang menyebebkan gangguan kesehatan manusia disebut pencemaran udara. Salah satu jenis pencemar sangat perlu diperhatikan yaitu akibat pengoperasan mesin seperti Pembangkit Listrik Tenaga Uap (PLTU). PT. X merupakan perusahaan menggunakan pembangkit listrik tenaga uap berbahan bakar b...

برای دستیابی به مزیت رقابتی در شرایط عدم‌­اطمینان که آن تغییر ضروری است، یکی از چالش‌های بزرگ سازمان‌ها کاهش ریسک طریق ایجاد زنجیره‌های تأمین تاب‌آور است. تاب‌آوری زنجیره ‌تأمین توانایی مقابله با اختلال اشاره دارد یک رویداد غیرقابل‌پیش‌بینی بوده و دارای منابع داخلی خارجی مختلفی ازجمله بلایای طبیعی ریسک‌های عملیاتی پژوهش حاضر شبیه‌سازی توسط نرم‌افزار ارنا زنجیره‌ سنگ ساختمانی «کارخانه سنگبری آسم...

Pollutant dispersion modeling in around Yogyakarta International Airport wasconducted using AERMOD software. There is a strong positive correlation between the number of aircraft and land transportation pollutants considered. The ambient air quality at study site for all originating from landing take-off (LTO) cycle still below standards, but those sourced combination LTO transport traffic NO2 ...

For the assessment of regional to local air quality in urban and industrial areas, a system of coupled models (AirWare) that cover several levels of nesting from regional (several hundred kilometers) to city level and street canyons has been developed in EUREKA E!3266 WEBAIR. The main objectives are to support regulatory tasks, compliance monitoring, and public information, and to provide a rel...

Land and forest fires in West Kalimantan have been going on for a long time recent years it has gotten worse with the increasing number of hotspots which reduced visibility due to haze. This decrease reaches considerable distance from source fire. condition an impact health problems, transportation, population density. Bengkayang Regency was chosen as location prototype site nuclear power plant...

The present study focuses on the spatio-temporal variation of nitrogen dioxide (NO2) during June 2013 to May 2015 and its futuristic emission scenario over an urban area (Durgapur) of eastern India. The concentration of ambient NO2 shows seasonal as well as site specific characteristics. The site with high vehicular density (Muchipara) shows highest NO2 concentration followed by industrial site...

Abstract: Within the American Society for Testing and Materials (ASTM) a Standard Practice (Z6849Z ) is being developed to provide an objective statistical procedure for comparing air quality simulation modeling results with tracer field data. The practice is limited to steady-state local-scale transport from isolated point sources in simple terrain. Evaluation data having similar external cond...
