Judul: Prediksi Pola Aliran dan Distribusi Suhu Udara pada Rumah Tanaman Tipe Modified Standard Peak di Kecamatan Dramaga, Bogor
Abstrak: Greenhouse is a building disigned and built to protect the plants from unfavorable environmental conditions. Design of greenhouse in tropics must be considered, so that air temperature in greenhouse are not too high. Simulation study of air temperature distribution is very important for basic design of greenhouse. The purpose of this research was to study and predict air flow pattern and temperature distribution in modified standard peak greenhouse. Parameters measured in this research were air temperature, solar radiation, air humidity, and wind speed. Data were recorded every 30 minutes, started from 06.00 am to 06.00 pm. Results showed that the highest air temperature occured in around the roof area, as influenced by chimney effect and greenhouse effect. Results also showed that air flowed from outside to inside greenhouse. It were caused by differences in air density. Validation results were 90% and errors less than 10% , so it can be concluded that simulated model was valid for environment greenhouse.

Abstrak: Greenhouse design for the humid tropical regions is still a challenge. Microclimate analysis of a standard peak type greenhouse has been conducted using Computational Fluid Dynamics (CFD). The objectives of this research were to simulate temperature, humidity, and airflow distribution by using CFD, and to investigate the greenhouse natural ventilation performance on zero and low windspeed conditions. Climate data and greenhouse characteristics were used as inputs for the simulation. The CFD model predicted temperature, relative humidity, and airflow distributions inside the greenhouse. Visual representations of the three parameters distributions in the greenhouse were created by isothermal line. The simulation produced realistic approximations of the dynamic behavior of greenhouse environments. Results of this study showed the importance of roof vents and sidewalls openings for efficient thermally driven ventilation

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.
