Identifikasi Kenyamanan Termal Bangunan (Studi Kasus: Ruang Kuliah Kampus Ipb Baranangsiang Dan Darmaga Bogor)identification of Building Thermal Comfort (Case Study: Classrooms in Ipb Banangsiang and Darmaga Campuses)

Housing development, well-planned or not well-planned, has changed urban view and its thermal environment. Many researchers have claimed that the worse quality of urban thermal environment is proportional to physical development of the city. Physical development in urban areas has caused various environmental problems, one of them is the change in quality of thermal environment by which the city becomes hotter than the surrounding areas. The purpose of this research was to identify thermal comfort either in classrooms at Darmaga or Baranangsiang campuses of Bogor Agricultural University. PMV (Predicted Mean Vote), using the boundary Effective Temperature (TE), THI (Temperature Humidity Index), and the last method is respondent test. PMVs (Predicted Mean Votes) in the classrooms at Baranangsiang campuses are thermally neutral to slightly warm, while that in classrooms in Darmaga campus are warmer. Effective Temperature which is resulted in the both of lecture halls are comfortable warm conditions. In addition, for respondents test, the thermal impression in IPB campus of Baranangsiang prefers to choose the slightly warm conditions, but for a lecture hall in campus of IPB Darmaga is more dominated by warm and slightly warm conditions. The questionnaire has been appropiated to the range of PMV index. So, the lecture halls that have been studied in both of campus can be concluded as slightly warm condition, because the thermal impressions felt by the respondents are also in the range of neutral to slightly . The value of THI for both of campus environment is in the range of moderate or neutral.Housing development, well-planned or not well-planned, has changed urban view and its thermal environment.

Pemanfataan Data Equatorial Atmosphere Radar (Ear) Dalam Mengkaji Terjadinya Monsun Di Kawasan Barat Indonesia(the Valuable of Equatorial Atmosphere Radar (Ear) Data to Study Monsoon in the West Area Indonesia)

Kototabang, Padang Panjang and Sicincin city are area in the West part of Indonesia and they are relative in the equator line. Otherwise, three of these cities have difference of behaviors of rainfall for Monsoon. In this study, we were used EAR Data, which were including the rainfall Kototabang, Padangpanjang, and Sicincin. Base on this data (i.e EAR data) in Kototabang, there is monsoon in 8-18 km layer and the higher monsoon is in 14 km layer during the April 2002-April 2006 period. Analisis Power Spectral Density (PSD) and Transformasi wavelet were shown that Monsoon oscillation around 12 months. While vertical profile was presented that the stronger monsoon will be in the wet weather on January. The domination of wind in Kototabang city is South Wind, it is because the wind took water vapor mass from South to North. According to analysis of rainfall in Kototabang, Padangpanjang and Sicincin City, meridional wind in the the Sicincin has rainfall pattern the same as with monsoon. Its was indicated that there were local indicator which can cause the monsoon. From the cross correlation between meridionial wind speed with rainfall in Kototabang, Pontianak and Sicincin, they were shown that three of these cities have significant correlation

Variasi Spasial Dan Temporal Hujan Konvektif Di Pulau Jawa Berdasarkan Citra Satelit(spatial and Temporal Variation of Convective Rain in Java Island Based on Citra Images)

Convective rain is one of precipitation types that usually occur in Indonesia, result by convective process. This convective rain brings heavy rainfall in short period and could reach a higher intensity than common monsoon rain. Convective process may have a variation with time and location. This research have determined spatial and temporal variation of convective rain in Java island by using the black body temperature (TBB) gradient method based on the GMS-6 (MTSAT-1R) images. As a result, the seasonal convective rain generally occurred in similar period i.e. in the morning from 07.00 to 11.00 LT (local time) and in the evening from 18.00 LT until 05.00 LT. The maximum event occurred from 18.00 LT until mid night. There were different locations between the seasonal convective event. In the seasonal convective rain, there were two spatial patterns. In wet season (DJF) and transitional season from wet to dry (MAM) convective rain spread from east to west Java. While in dry season (JJA) and transitional season from dry to wet (SON), convective rain mostly occurred only in west Java
