Abstrak: Green roof is one of a way to make an environmental building because it can reduce the use of fossil fuel and CO2 pollution. Nowadays green roof has been used in several countries to reduce an environmental impact from building which can worse the condition of thermal comfort. This research was conducted to find out the thermal comfort conditions of class room B1 belongs to the Faculty of Economics and management (FEM), IPB. This research purpose are to know about the existing condition of the classroom B1 thermal comfort and to comparing the thermal comfort of the room if the building use a green roof, and then make an optimalization of the wall openings. Green roof convered by a kind of landscape schrub which call pineapple.In this research has been analysed temperature, humidity, and air flow in several height using a simulation technique base on Computational Fluid Dynamics (CFD). The simulation is carried out using the program SolidWorks 2012. This research result show that the highest temperature at 13.00 PM showed 30,37°C, humidity 77,44%, and air flow 0,014 m/s. The thermal comfort using the green roof are temperature 28,48°C and humidity 75,19%. The thermal comfort with wall opening are temperature 27,97°C and humidity 50,02%. The standard for thermal comfort room that is 22-29°C, humidity 30-50%.

Judul: Analisis Kenyamanan Thermal Ruang Kelas B1 FEM IPB Menggunakan Teknik Simulasi Berdasarkan Computational Fluid Dynamics
Abstrak: Classrooms contstruction have to consider about thermal comfort, so that learning activities can be done effectively. The thermal comfort can be achieved by saving our nature with minimizing energy consumption and environment damage. This research is analyze thermal comfort of B1 Classroom FEM IPB which now used an outdoor concrete roof. The research objective is to determine the climate of B1 classroom using simulation technique. The simulation is done to determine and compare the dynamics of airflow pattern, temperature, and humudity of concrete and plant yard. The simulation was conducted based on Computational Fluid Dynamics method. The result shows that plants yard is can decrease temperature and increase the comfortable in B1 classroom than existing condition. The compare of thermal comfort condition in existing, concrete and plant outdoor yard are 28.5oC, 28.3oC, dan 26oC. The airflow rate in B1 classroom with plants yard is 0.237 m3/min/person and it reach a suitable condition based on SNI 03-6572-2001.

Abstrak: Ikan tenggiri adalah salah satu ikan ekonomis penting yang dijual untuk memenuhi pasaran lokal dan salah satu komoditi ekspor. Untuk menjaga kualitas ikan tersebut, maka perlu dik etahui tentang stok dan parasitnya. Studi parasit merupakan salah satu informasi penting dalam bidang ekologi seperti peranan parasit pada suatu ekosistem dan informasi dasar bagi industri perikanan dalam menjaga kualitas ikan, dan dalam bidang manajemen, kemungkinan dapat juga digunakan sebagai indikator stok populasi ikan.
