Judul: Analysis on Ecohouse’s space arrangement and airflow in rural area.
Abstrak: This paper explores the potential of temperature distribution using ventilation and natural convection in a Eco-house’s space arrangement and air flow in rural area by natural air cooling system for a construction designs as an illustrating Eco-House in Indonesia. The characteristics of the construction are analyzed in terms of heat and mass transfer and also air circulation by the Computational Fluid Dynamic method and practice. Based on the thermal comfort requirements of the Indonesian National Standard (SNI), the study has found that it is possible to use natural ventilation to create a thermally comfortable indoor environment in Eco-houses. This study also develops comprehensive design guidelines for natural ventilation at both the site planning and individual compartment house levels, using the specific materials. Finally by the simple geometry and calculation following the technical design temperature distribution in any point inside Eco-house will be predictable.

Judul: Desain Tata Ruang Bangunan Eco-house Menggunakan Computational Fluid Dynamics (CFD) pada Iklim Tropis
Abstrak: Eco-house is the application of ecological design where its layout considering the thermal problems in a room, the use of energy and sustainable resources. The objectives of this research is to design the Eco-house’s layout which can be inhabited by farmers and focused on aspects of the thermal comfort in tropics. Eco-house was designed by using Computational Fluid Dynamics (CFD) method. The design process is started by the validation of CFD simulation of Laboratory of Environmental Engineering of Biosystem which is the accuracy of simulation result is tested and validated. The same design process of CFD simulation is applied to the process of designing Eco-house's layout. The designs of Eco-house's layout utilize natural ventilations sistem with the design of the wind and the combination of wind and thermal effects. Design of ventilation combination of results of simulation comfort are qualified with the equivalent temperature distribution of 24.65 oC, wind velocity of 0.5-0.8 m/s and relative humidity of 65%. The additional of roof vents and designing the building perpendicular to the direction of wind supports the thermal comforts requirement.

Judul: Profil Eritrosit Anjing Beagle Setelah Pemberian Obat Anti Caplak Afoxolaner Lima Kali Dosis.
Abstrak: Afoxolaner banyak digunakan untuk mengobati dan mencegah infestasi caplak pada anjing. Senyawa tersebut memiliki efektivitas yang tinggi dan mampu mencegah reinfestasi sebulan sejak diberikan. Hingga saat ini belum diketahui efek afoxolaner terhadap profil eritrosit anjing. Afoxolaner diberikan kepada enam anjing beagle (8-12 bulan) yang secara klinis tidak terinfestasi caplak. Anjing dibagi menjadi dua kelompok perlakuan yang berbeda. Kelompok 1 diberikan sediaan afoxolaner sebanyak satu kali dosis anjuran sementara kelompok 2 diberikan lima kali dosis anjuran. Pemberian sediaan afoxolaner dilakukan sebulan sekali sebanyak tiga kali pengulangan dengan jarak antar pemberian satu bulan. Sampel darah diuji menggunakan hematology analyzer MEK-6450 dan data dianalisis menggunakan perangkat lunak SPSS 16.0. Hasil yang didapat menunjukkan bahwa secara statistik tidak ada perubahan signifikan antara profil eritrosit anjing beagle sebelum dan sesudah pemberian sediaan afoxolaner. Disimpulkan bahwa pemberian sediaan afoxolaner lima kali dosis anjuran secara oral tidak memengaruhi profil eritrosit anjing beagle.
