Air pollution was influenced by meteorological condition. Atmospheric stability and wind are very important meteorological factors such as solar radiation, temperature, relative humidity, wind and its stability. This study analyzes the influence of meteorological factors to PM10 concentration in Bandung, West Java, as the case study. We used the data from Air Quality System Monitoring (AQMS) at Dago Pakar Stastion as the refference of background area and Cisaranten Wetan as the refference of industrial area. This study used multiple linear regression method to analyze the influence of solar radiation, temperature, relative humidity (RH) and wind velocity to concentration of PM10. The result of this analysis is the meteorological factors that influence PM10 concentration are different for both of location. At Dago, wind velocity is not a significant factor influencing fluctuation of PM10 concentration. However, for Cisaranten Wetan it significantly influences the PM10 concentration with negative correlation. The meteorological factors at Dago that significantly influence PM10 concentration are solar radiation (Rad), temperature (T) and relative humidity (RH), with the equation Yi = -87.334 + 0.023Rad + 3.184T + 0.621RH; while at Cisaranten Wetan, the significant meteorological factors are radiation, relative humidity and wind velocity (V), with equation Yi = 16.0842 + 0.028Rad + 0.504RH - 9.184V. Wind velocity at Cisaranten Wetan had a larger range than that of Dago. This wind has a velocity of 5 m/sec which potentially transports particulates to other areas that can decrease PM10 concentration.

Nowadays, acid rain is a common phenomenon occurring in metropolitan city, such as Jakarta. Human activities including transportation and industries in and surrounding this city have increased pollutants in the atmosphere, which lead to an increased of acid rain events. Analyzing on rainwater pH is common approach to assess whether an acid rain occurs or not. However, information on this pH value for greater Jakarta is limited. Here we used a combined of Henry's law approach and Weather Research Forecasting-Chemistry (WRF-Chem) to estimate rainwater pH in Jakarta. The WRF-Chem was employed to generate SO2 and NO2 concentrations. Results showed that rainwater pH is below the threshold (pH = 5.6) in observation and modeling (Henry’s approach) throughout greater Jakarta. Rainwater pH showed a diurnal fluctuation with low value during night and morning, but high value at afternoon. Likely, season contributed to distribution of acid rain. Based on Henry’s approach, some regions (Bundaran HI, Kebon Jeruk, and Jagakarsa) revealed a high potency of acid rain for rainy season as indicated by the H+ concentration. On other hand, a high potency of acid rain during dry season was observed in Kelapa Gading and Bundaran HI. Our findings indicated that traffic may influence on rain acid events as shown by a high H+ concentration in Bundaran HI both dry and wet seasons.

Car Free Day (CFD) is a social campaign aimed to reduce the dependence of people on vehicle uses, which occurs once per week in Bogor. The idea intends to decrease the vehicle emissions. However, CFD is often to cause a new problem like the congestions, which are found on the nearby alternative roads, as happened in RE Martadinata Street, Bogor City. This study aims to compare the emission load and the concentrations of pollutants in ambient air during CFD (06.00-09.00 am) and non-CFD days in alternative road. We measured the following pollutants: CO, HC, NOx, PM10 and SO2. This research first applied Fixed-Box Model to estimate concentration of pollutants, then we used the Finite Length Line Source (FLLS) to estimate dispersion of pollutants. The results showed that there was no substantial difference in pollutant emissions between CFD and non-CFD days. But if we separate between weekdays and weekend, our analysis revealed that emissions during the weekend are bigger than that of weekdays. This was consistent with an increase of number of vehicles during the weekends by 17.2%. Based on our analysis, motorcycle contributes to an increased of CO, HC, PM10 pollutants, whereas SO2 and NOx pollutants were generated by cars. Our findings suggest that a short time of CFD does not contribute a lot to reduce the emissions.

Pneumonia is the respiratory infection disease, which is influenced by climatic variables and air quality. However, little is known how rainfall and air humidity influence on the disease situated in a high traffic density such as in Bogor, Indonesia. The research aims to analyze the influences of rainfall, air humidity, and air pollution on the incidence rate of pneumonia under 5-year old children in Bogor. We used statistical approaches namely correlation and principal component analysis and combined with chart analysis to identify the influences. Our results revealed that high rainfall (high relative humidity) improved air quality by lowering the concentration of particulate matter. But, the indoor microorganism growth would increase, therefore it affects the incidence rate of pneumonia under 5-year old children, especially in transition season from wet to dry. In dry season, high concentration of particulate matter in the air would increase the incidence rate of pneumonia. Other findings showed that climate (through humidity) and particulate matters have regulated the pneumonia incidence rate in Bogor. The rate was higher under high humidity. On other hand, in transition from dry to wet season, concentration of particulate matters was more dominant to influence the incident rate.

Forest and land fires have become disasters that have received international attention. Peatland as an important part of the forest poses a separate threat to the effect of carbon release and climate change. Fire prevention can be done by understanding the causes. Fire vulnerability mapping uses several parameters in its calculation, namely NDVI value, NDMI value, TWI value, accessibility distance, and community activity center. Land use and hotspot history will be the parameters compared with the results of the analysis. The calculation uses a range of values from 1 to 5. The risk level class is divided into five, with the highest percentage of 20.18% at the very vulnerable level and the lowest of 19.56% at the normal level. Very vulnerable areas have the highest number of hotspot points at 268 points while the lowest number of hotspot points is in the safe class of 23 points. Most areas with high vulnerability are found in agriculture and plantation areas. The model used in this fire vulnerability map can be said to have a pretty good correlation. Keywords: accessibility distance, forest fires, hotspot, land use, peatland

Banjir merupakan salah satu bencana yang menimbulkan kerugian bagi manusia. Bencana tersebut biasanya didahului oleh curah hujan yang tinggi (lebat) dan lama. Proses terjadinya hujan yang tinggi dan lama memerlukan kondisi atmosfer yang mendukung seperti . Tujuan utama penelitian ini adalah menjelaskan kondisi atmosfer pada saat banjir di Kabupaten Bojonegoro tanggal 26 Desember 2007 sampai 7 Januari 2008. Hasil analisis menunjukkan bahwa kondisi atmosfer saat banjir tidak stabil, kandungan uap air tinggi, pengangkatan massa udara intensif dan kecepatan angin rendah. Kondisi tersebut cukup potensial dalam menyebabkan hujan yang lebat, meskipun kondisi atmosfer tersebut belum termasuk kategori ekstrim. Dengan demikian banjir tersebut tidak hanya dipengaruhi oleh kondisi atmosfer setempat tetapi dipengaruhi juga oleh kondisi atmosfer sekitarnya dan kondisi permukaan. Flood is one of the disasters that cause harm to humans. That disaster is usually preceded by heavy and long-term rainfall. The occurrence of high and long-term rainfall requires atmospheric conditions that supported it. The main objective of this study is to explain the atmospheric conditions while flood events in Bojonegoro on December 26th, 2007 until January 7th, 2008. The analysis showed that the atmospheric conditions are unstable during floods, high moisture content and the removal of intensive air mass and low wind speeds. The atmospheric condition during the flood was sufficient to support the heavy rain but not in extreme categories. Therefore, the flood-affected by atmospheric conditions in the surrounding area and surface conditions in that area.
