Judul: Tingkat Kenyamanan Kampus IPB Baranangsiang Berdasarkan Informasi WBGT (Wet Bulb Globe Temperature).
Abstrak: The measurement of wet bulb temperature (Twb), dry bulb temperature (Tdb), and black globe temperature (Tbg) are used to assess the comfort index of human outdoor and indoor at IPB Baranangsiang campus based on Wet Bulb Globe Temperature (WBGT) index. WBGT is a temperature composision to estimate the effect of air temperature, relative humidity, and solar radiation to human comfort. If Tbg data not available, Tbg can be predict by air temperature, relative humidity, and solar radiation. They explain the variability of Tbg data is 98,84% for outdoor and for indoor, without radiation explained, the variability is 98,65%. The average range of WBGT indoor and outdoor such as Botani, Fisika, Bsp01, Bsp02 class room and garden colection for morning are 24,3-24,8ºC, after noon are 28,2-31ºC, and evening are 26-27ºC. The relationship between WBGT with comfort index indicates is respondence feel comfortable when the value of WBGT is low and not comfortable when the value of WBGT is high. The results of this study show that the WBGT value is higher than WBGT standart in temperate region (subtropic)

Judul: Identifikasi kenyamanan termal bangunan: studi kasus kampus IPB Baranangsiang dan Darmaga Bogor
Abstrak: Housing development, well planned or not well planned, has changed the view of city and thermal environment. Many researchers claim that the worse quality of thermal environment is proportional to physical development of cities. Physical developments in urban areas have caused various environmental problems, one of them is the change in quality of thermal environment, become hotter than surrounding areas or natural areas. The purpose of this research is to identify the thermal comfort either in campus classrooms Darmaga or Baranangsiang IPB, Bogor. The method used is directly observational data in classrooms and campus. Index PMV (Predicted Mean Vote), using the boundary Effective Temperature (TE), THI (Temperature Humidity Index), and the last method is respondent test. The results of PMV ((Predicted Mean Vote) in lecture hall of campus IPB Baranangsiang and Darmaga are thermally neutral to slightly warm, though actually the lecture hall in campus IPB Darmaga is warmer. Temperature effective 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.

Judul: Konversi Asam Stearat dan Asam Oleat Menjadi Senyawa Oksazolina dengan Katalis Zeolit Teraktivasi Berbantuan Gelombang Mikro.
Abstrak: Oksazolina adalah senyawa heterosiklik dengan R tertentu dapat digunakan sebagai antikorosi karena mempunyai kerapatan elektron yang tinggi sehingga dapat terabsorpsi kuat pada permukaan logam. Penelitian ini bertujuan menyintesis senyawa 2-heptadesil-4,5-dihidrooksazol dan (Z)-2-heptades-8-en-1- il-4,5-dihidrooksazol dengan melakukan konversi dari asam stearat dan asam oleat menggunakan aminoalkohol sebagai reagen dan zeolit teraktivasi sebagai katalis berbantuan gelombang mikro pada beragam daya. Daya optimum ialah 300 W. Rendemen yang diperoleh yaitu 55% untuk senyawa (Z)-2-heptades-8-en-1-il-4,5- dihidrooksazol dan 6,5% untuk senyawa 2-heptadesil-4,5-dihidrooksazol. Stuktur oksazolina dicirikan berdasarkan spektrum inframerah yang menghasilkan pita spektrum baru pada bilangan gelombang 1650 cm-1 dan 1044 cm-1, masingmasing untuk gugus fungsi imina dan eter, selanjutnya dicirikan dengan teknik resonansi magnetik inti.
