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: Analysis Of Thermal Comfort Using Modern Building Material In Baduy Dalam House With Computational Fluid Dynamic
Abstrak: Eco-house is the applying of an ecological design on building. In Indonesia, Baduy Dalam community are examples of people who still have and perform local knowledge in their lifestyle including implementing ecological design in their homes. In this research, has been performed an analysis of thermal comfort in Baduy Dalam homes. The analysis had been performed by using three combinations of roof, wall and floor materials in Baduy Dalam’s house which are ceramic- brickceramic; concrete-brick- ceramic and asbestos cement-brick-ceramic. The analysis performed by a simulation techniques using a computer program Computational Fluid Dynamic (Solidworks 2011) to get a distribution model of air temperature, air movement, and relative humidity(RH) in the building. The input of environmental data such as temperature, RH, solar radiation, and wind speed used a 13 November 2010’s datas. The simulations carried out at 11:00, 13:00, 15:00, 19:00, 21:00, and 23:00. The simulation results of the most unsatisfied thermal comfort conditions using a combination 1 materials are; temperature 55.52°C, RH 20.71%, air flow 0.064 m/s, combination 2 are temperature 59.58°C, RH 17.10%, air flow 0.085 m/s, and combination 3 are; temperature 50.56°C, RH 24.14%, and air flow 0.065 m/s. The simulation results show that the worst conditions are combination 2 (concrete roof, brick walls and cement floor). The highest temperature is 59.58 ° C at 13:00. Modifications is made to the worst house condition by adding vents on the Baduy Dalam house and the results are temperature was -22.07°C lower at Imah and -22.24°C lower at Tepas.

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.
