Judul: Analisis transmisi radiasi surya oleh uap air (water vapor transmittance) menggunakan kanal infra red dekat (near infrared band) data satelit modis l1b (terra)
Abstrak: Uap air memiliki kemampuan untuk menyerap gelombang elektromagnetik, sehingga tidak semua gelombang elektromagnetik lolos melewatinya. Besar kisaran panjang gelombang yang mampu diloloskan oleh uap air disebut sebagai transmitan uap air. Pendugaan nilai transmitan uap air dapat digunakan sebagai indikator terhadap pertumbuhan awan. Data penginderaan jauh yaitu Terra MODIS LIB dapat digunakan untuk menurunkan informasi transmitan uap air berdasarkan rasio antara kanal diserap oleh uap air (kanal absorbsi) dan kanal yang tidak diserap oleh uap air (kanal non absorbsi). Kanal absorbsi antara lain kanal 17, 18 dan 19, sementara kanal non absorbsi yang digunakan adalah kanal 2 dan 5. Kelima kanal tersebut merupakan kanal infra merah dengan kisaran panjang gelombang 0.865 µm sampai 1.240 µm. Hubungan antara nilai transmitan uap air pada kanal 17, 18 dan 19 dengan suhu permukaan awan memiliki pola yang linier dengan koefisien determinasi masing-masing sebesar 0.619, 0.874 dan 0.834.Hasil analisis hubungan antara transmitan uap air dan suhu permukaan awan menunjukkan semakin rendah nilai transmitan maka suhu permukaan awan akan semakin tinggi. Suhu permukaan yang tinggi menunjukkan kadar uap air masih tinggi sehingga tingkat pembentukan awan masih rendah.

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: Biology Of Columbia Lance Nematode (Hoplolaimus Columbus Sher) On Soybean Excised Root Culture
Abstrak: S. Supramana, S. A. Lewis,.J. D. Mueller, B. A. Fortnum, and R. E. Ballard. 2001. Biology of Columbia lance nematod. ~ (Hoplolaimus columbus Sher) on soybean excised root culture. Nematropica 31 :283-2~)O. Feeding, egg development and oviposition, embryology, and postembtyonic development or Hoplolaimus col'lmbuswere observed on soybean (cultivar Hutcheson) excised root culture in Gam borg's B5 medium (pH 5.7,1.3% agar). Petri plate sterile cultures were placed inverted on a heated microscope stage (30°C) and observations were conducted using a color video camera and a time lapse digital videoca:;sette recorder. Oocytes were obsetved in each gonad 38 hours after feeding commenced and all egg possessing a terminal stalk was laid 96 hours later. Eggs were deposited it, the one-celled stag~ and a total of 217 hours (9 days) was required for a"newly laid egg to develop into a hatching second-stage juvenile at 30°C. Postembryonic development consisted of threejuvenile stages and an adult female with prior feeding occurring before molts and oviposition. The nematode fed ectoparasiticallyon the subepidermal cells and endoparasitically in the cortex and outer vascular tissue and remained at the infection site for 2·9 days. Key words: Columbia lance nematode, embryology, excised root culture, feeding behavior, HOfilo{aimus columbus, life cycle, oviposition, postembryonic development, soybean.
