Judul: Relationship Between Urban Green Space and Surface Temperature By Using Image LANDSAT TM/ETM+ (Region : DKI Jakarta)
Abstrak: Urban Green Space (RTH) is regions covered by different types of vegetation in order to support direct and indirect benefits for the comfort and well-being. Jakarta has a rapid land cover changes every year, and the increased activity of the city brought an indirect impact on climate in the component elements. RTH reduction affects climate elements, one of which is surface temperature. Surface temperature is strongly influenced by the conditions of closing its land because of the nature of emissivity and thermal conductivity. This study examines the relationship between green space and the surface temperature using remote sensing techniques of LANDSAT satellite in 1992, 1997, 1999, 2000, 2001, 2004, and 2006. The technique used to determine the value of green space that is a supervised classification of various types of closure land use channel 5, 4, 2 (RGB), and to determine the surface temperature is used channel 6 (thermal) by processing the spectral radiance values and the digital number. The area of green space in a row in 1992, 1997, 1999, 2000, 2001, 2004, and 2006, was 42.2%, 32.1%, 29.7%, 27.4%, 26.3%, 22.5%, and 19.3%. While the surface temperature values obtained by the RTB 29oC-42oC, 27oC-30oC RTH, and a body of water 17-26oC. Surface temperature is strongly influenced by the conditions of closing its land, so the reduction in green space contributes to an increase in surface temperature.

Judul: Hubungan Ruang Terbuka Hijau (RTH) dengan Temperature Humidity Index (THI) Kota Depok
Abstrak: Urban green space is an elongated area /point and /or clustered, the use of which is more open, a place to grow plants, whether grown naturally or are deliberately planted. Urban green space has a great benefit to the environment of the city, including the benefits of climatological, ecological, aesthetic, and tourism. Depok City is a strategic area for the capital city of Jakarta because of Depok has a function as a buffer zone in southern Jakarta. This study attemps to estimate values of air temperatures using Landsat data, functional relationship between air temperature and urban green space, and also relationship between urban green space and temperature humidity index in Depok City. Air temperature are derived from Landsat data using energy balance method, while urban green space are classified by using unsupervised method. Estimation air temperature of Depok City in 2001, 2002, 2004, 2005, and 2006 are 24.5 oC, 25.5 oC, 26 oC, 26 oC, and 30 oC, while urban green space are 63%, 57%, 55%, 55%, and 42%. Functional relationship between air temperature and urban green space for the study area best represented by a non-linier equation. Temperature humidity index values of depok city in 2001, 2002, 2004, 2005, and 2006 are 25.oC, 25 oC, 26 oC, 26 oC, and 27 oC.

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.
