Abstrak: Regional heat capacity change is calculated from the ratio between the addition or subtraction of heat (ΔQ) with the increase or decrease in temperature (ΔT) region. The purpose of this study is to calculate the regional heat capacity change due to the changes of land cover composition with forest, shrubs, oil palm plantation and bare soil using Landsat-5 TM satellite data on 1994, 2000 and 2010. Total area that used on this study is 12971 ha. In 1994-2000, 4 % of forest area and 2% shrubs were increased, followed by additional of biomass forest 4.01 tons/ha and 2.83 tons/ha for shrubs. The increased of forest area and biomass (tons/ha) caused by forest and shrubs growth processing towards climax that added the canopy volume. So that, the regional heat capacity in 1994 amounted 19384 MJCo-1 increased to 19929 MJCo-1 in 2000. Data observation for 2000-2010 showed that forest area decreased by 66% due to forest’s clearing into oil palm plantations (47%), shrubs (8%), and bare soil (11%). But, plant’s biomass continue to increased, i.e 1.48 ton/ha for forest, 2.73 tons/ha for shrubs and 4.63 tons/ha for bare soil. Before 2000, there was no land cover by oil palm plantations, so the increasing rate from this land was the biggest than the three other lands, amounting to 122.29 tons/ha. Decreasing in the percentage of forest area does not cause a decrease in the heat capacity of the region. Intensive maintenance on oil plam plantation such as water management, fertilizer and planting space made it biomass productivity and ability to save the heat is greater than the forest. As the result, in 2010 regional heat capacity increased to 22508 MJCo-1.

Judul: Hubungan antara Titik Panas dengan Perubahan Penutupan/ Penggunaan Lahan (Studi Kasus: Kabupaten Kapuas, Provinsi Kalimantan Tengah)
Abstrak: Land and forest fires in Indonesia have become a serious problem since 1982/1983. Annually the area that was burned widespread, which is caused by the increasing number of forest converted to plantations, agriculture, settlements, and so forth. Indicator commonly used for early detection of forest and land is hotspots, obtained from a meteorology satellite remote sensing. The objectives of this research are to analyze the distribution pattern of hotspots in Kapuas District, analyzed land cover/use change in Kapuas District, analyzed the relationship between hotspots and land cover/use change in Kapuas District, and analyzed the relationship hotspots and rainfall anomaly in Kapuas District. The maximum distribution of hotspots during 2005 to 2011 was indicated in 2006 and 2009; it was expected because of the effect of long term dryness (El-Nino), so the intensity of the fire increased. During 2005 to 2011, many hotspots identified in shrub swamps, shrub, plantations, secondary swamp forest, and secondary upland forest. Hotspots are identified on the site, possibly due to a fire caused by the preparation of agriculture or plantation. It is marked by an increase in land cover change to plantation up to 49.5%, while the secondary swamp forest and secondary upland forest decreased up to 19.2% and 7.83%. The rainfall anomaly is also expected to be able to affect the number of hotspots. When rainfall in the condition of subnormal, then hotspot identified more than when rainfall was above normal.

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.
