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: Aplikasi pengindraan jauh untuk menduga suhu permukaan dan udara di lahan gambut dan mineral dengan menggunakan metode neraca energi: area study Sampit, Kalimantan tengah
Abstrak: Prediction using satellite imagery can be very useful if used to estimate the temperature in different regions with different land cover types. This study aims to analyze the surface and rising air temperatures in peat lands and minerals, with the energy balance approach using satellite image data TM / ETM +. The methodology undertaken is the determination of the study area, initial processing of satellite images that include: data import images, geometric correction, radiometric, land cover classification, extraction of surface temperature values and calculate the components of energy balance to determine the value of air temperature. The results showed that land use change on mineral and peat soil for 15 years resulted in increased surface temperatures and air temperatures. The range of average surface temperature as a whole in 1989 for mineral soil and peat (27-41) oC, In 2004 the surface temperature of the mineral soil (32-40) oC, and peat (29-35) oC, and the average value range of temperatures (25-36) oC. On the other hand detection of surface temperature using thermal bands of satellite imagery, should pay attention to aspects of the use of their land to avoid misinterpretation, because the condition of land cover types were very influential in the increase or decrease the temperature of the sector in a region.

Judul: Enteric Collibacillosis Pada Anak Babi Baru Lahir: Patogenesa dan Perubahan-Perubahan Patologisnya
Abstrak: Diare disebabkan oleh infeksi bakteri Escherichia coli pada anak-anak babi baru lahir yang peka terhadap en terotoksin produk bakteri tersebut. Dikenal sebagai colibacillosis. Patogenesa dari colibacillosis anak babi baru lahir adalah (1) infeksi oleh E. coli patogen, (2) proliferasi E. coli di lumen usus halus, (3) produksi dan pelepasan enterotoksin, dan (4) aktifitas toksin pada usus halus. Dalam proses proliferasi, adanya antigen pili K88 sangat penting karena memungkinkan bakteri perlekatan dengan epitel mucosa usus halus. mengadakan Setelah ko lonisasi dan proliferasi segera toksin dilepaskan. Akti- fitas toksin menginduksi sekresi yang berlebihan dari u- sus sehingga banyak cairan yang dikeluarkan ke lumen usus. Hal ini mengakibatkan banyak cairan dan elektrolit hilang sehingga timbul diare, dehidrasi dan asidosis yang sering menyebabkan kematian. Perubahan-perubahan patologis yang umum adalah dis tensi usus halus, dilatasi lambung dan infark pada kurva- tura mayor. Perubahan-perubahan histologis yang terjadi adalah enteritis hemorrhagica acuta, oedem dan kongesti pembuluh darah di lamina propria, akumulassi leukosit inti polimorf, sel monosit, dan inti sel mengalami piknosis Thrombus pada vena dan degenerasi serta desquamasi sel epitel usus….
