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: Metoda intramedullary pin sebagai salah satu cara menanggulangi fraktur femoralis pada anjing
Abstrak: Metoda intramedullary pin merupakan salah satu metoda penanggulangan fraktur yang populer karena banyak mempunyai keuntungan, diantaranya adalah : cepat dan mudah dikerja- kan, fiksasi yang dihasilkan lebih kuat dibandingkan metoda plate, setelah sembuh tulang menjadi lebih kuat, dan biaya yang digunakan relatif lebih ekonomis. Beberapa macam intramedullary pin yang ada, diantara- Steinmann pin, Rush pin, Kirschner pin, Kuentscher nya : nail, dan Leighton Shuttle pin. Teknik pemasangan intramedullary pin dapat melalui operasi tertutup atau operasi terbuka, tergantung dari ti- pe dan derajat fraktur. Pada operasi tertutup tidak dila- kukan pembukaan terhadap lokasi fraktur. Penyisipan pin dilakukan melalui fragmen fraktur proximal diteruskan ke fragmen distal, sehingga pada metoda ini luka yang timbul hanya pada tempat dimana pin tersebut dimasukkan. Pada operasi terbuka penyisipan pin dilakukan melalui pembukaan lokasi fraktur. Dalam melakukan pembukaan terhadap lokasi fraktur, harus dipilih pendekatan yang paling sesuai dan paling sedikit kemungkinannya untuk menimbulkan komplikasi. Pengambilan pin biasanya dilakukan setelah empat atau lima minggu disisipkan, diharapkan pada waktu itu telah terjadi pembentukan callus yang sudah cukup kuat untuk me- nunjang berdirinya tubuh. Pada beberapa keadaan pin tidak perlu diambil, misalnya pada anjing tua atau pada anjing yang menderita penyakit tulang. Tidak ada reaksi sakit... akibat pin bertahan di dalam tulang.
