Judul: Pendugaan Hubungan Kondisi Topografi dengan Radiasi Spektral Citra Satelit TERRA MODIS L1B (Studi Kasus: Gunung Gede dan Gunung Salak)
Abstrak: The objectives of this research are estimate the spectral radiation relationship with the topography on forest land cover and analyze the relationship of surface temperature between altitude on forest land cover in the area of Mount Salak and Mount Gede derived from MODIS TERRA L1B imagery at long wavelength channel (spectral radiation emission ). Surface temperature derived from TERRA MODIS L1B data, it use channel 31 and 32 with a wavelength of 10.780 to 11.280 and 11.770-12.270 . Spectral emission of radiation (longwave thermal) response topography indicated by the correlation coefficient of -0.5 to -0.9 while the spectral reflectance of radiation (short wave) did not respond to the topography shown by fluctuations in the value of the correlation coefficient with a range of -0.7 to 0.3. TERRA MODIS L1B image data indicated by the response to topography radiation emission spectral response of the altitude. Based on data derived from MODIS TERRA L1B image is obtained inversely proportional relationship between the temperature of the surface topography. Highest value of surface temperature and the lowest occurred in September and May. With the same land cover (forest), solar zenith angle affects the surface temperature value. In addition, there are many other factors that affect the surface temperature, some of which are atmospheric effects (emission and scattering), the latitude and air density. MODIS sensor can respond to topography due to the influence of the moist air density and specific heat of air varies with altitude and pressure.

Judul: Pendugaan Nilai Suhu Permukaan Berdasarkan Data Terra-MODIS L1B dan SRTM 90m
Abstrak: Land Surface Temperature (LST) is one of the best indicators of the energy balance at the earth's surface and a key parameter in the physics of land surface processes that combine the interaction between long wave energy flux at the surface and in the atmosphere. Several methods for determining the value of LST with remote sensing data have been widely developed one of which is the use of Terra-MODIS satellite. MODIS has a mission to monitor the phenomenon on the surface and the atmosphere so that users can find information changes that occur in near-realtime. The purpose of this study is develop methods and algorithms using satellite remote sensing Terra-MODIS data for prediction and mapping LST and determine the relationship of surface temperature derived from Terra-MODIS satellite data with surface topography and land cover. LST determination was done by using the split window algorithm by including the main factors such as emissivity and brightness temperature. The results showed that average of the highest LST that the Vidal algorithm. The relationship between LST and altitude be obtained average of the highest R2 is in June/July whereas the lowest is in September/October. Further, the relationship between LST and land cover be obtained average of the highest LST value is on open land and built land whereas average of the lowest value is forest land. Solar zenith angle is greatly affect sensor accuracy to determination LST value

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.
