Judul: Development of Air Quality Index Parameters Measurement System Based on One-Dimensional Photonic Crystal Sensor
Abstrak: Pencemaran udara beberapa kota besar di Indonesia seperti Jakarta, Bandung, dan Surabaya telah mencapai tingkat yang mengkhawatirkan. Konsentrasi gas polutan dalam bentuk supended particulate matter (SPM), nitrogen dioksida (NO2), dan timbal (Pb) di atas standar yang ditetapkan oleh Organisasi Kesehatan Dunia (WHO) menempatkan Jakarta sebagai salah satu kota dengan Megacity Pollution Index (MPI) yang setara dengan Beijing, lebih tinggi dari Karachi dan Kairo. Urbanisasi dan industrialisasi merupakan penyebab utama polusi udara di negara-negara berkembang seperti Indonesia., Pollution at major cities in Indonesia such as Jakarta, Bandung, and Surabaya has come to an alarming extent. Concentration of pollutant gases in the form of suspended particulate matter (SPM), nitrogen dioxide (NO2), and lead (Pb) above the standards set by the World Health Organization (WHO) put Jakarta as one of the city with the Mega-cities Pollution Index (MPI) is equivalent to Beijing's tallest, higher than Karachi and Cairo. Urbanization and industrialization is a major cause of air pollution in developing countries like Indonesia.

Judul: Analisis Status Kualitas Udara Lima Kota Metropolitan di Indonesia.
Abstrak: The air pollution has become environmental quality indicator that impact to citizen health and affect the air quality in that area. The metropolitan city with rapid population rate and higher living standard as well as prosperity level than in rural area caused the increasing of energy consumption and pollutant emission. The aim of this study was to analyse the air quality status and the correlation between air quality and the condition of metropolitan cities in Indonesia namely Jakarta, Bandung, Medan, Surabaya, and Semarang. Secondly, to determine the factor affecting the air quality in those cities. The data were obtained from the State Ministry of Environment, BPS-Statistics, and the other related institutions which were then processed by SPSS program. Based on the analyzed data, the pollutant concentrations were fluctuated from 2007-2012 in those five cities. The positive correlation was occurred between the amount of vehicles and the concentration of PM10, SO2, and NO2, between the population and the concentration of SO2 and NO2, also between energy consumption and SO2. The negative correlation was occurred between the green open area with CO and NO2. Therefore, the factors that affect the air quality in metropolitan cities in Indonesia are population, vehicles, and green open area. Moreover, industrial estate and meteorological factor are allegedly to affect air quality in those cities.
