Judul: Pemanfaatan SIG dalam Pemetaan Potensi Merbau di Areal IUPHHK-HA PT. Wapoga Mutiara Timber Unit II Papua
Abstrak: Merbau is one of famous timber trade. Merbau included in the Fabaceae family which spread from Sumatera to Papua. Research on merbau potential mapping use geographical information systems (GIS) need to be conducted to obtain the data about potential merbau. This research is purposed to explain the most accuratest spatial interpolation method between inverse distance weight (IDW) method toward the kriging method, to explain the most accuratest number of variables, in order to create a map of merbau potential at IUPHHK-HA PT. Wapoga Mutiara Timber 2nd unit (PT. WMT-II) area. Merbau potential value in 2012 is calculated based on data of IHMB at PT. WMT-II. Unrepresented of merbau potential in IHMB plot was estimated by spatial interpolation. Potential map of merbau level of trees and poles are able to use IDW method with 4-classes that is very low, low, medium, and high. The combination of PG, PN, and PV variables with IDW is the best method to create potential map of merbau for each level. Potential map of merbau consist of 2 type map that explain merbau potential level of poles and tree at IUPHHK-HA PT. WMT-II area. Generally, potential of merbau in area of IUPHHK-HA PT. WMT-II as yet available for the level of trees in primary and secondary forest. But, average potential of merbau is low in secondary forest. It is also happened on the level of poles. It indicates that natural regeneration process of merbau is very low.

Abstrak: Comprehensive Periodic Forest Inventory (IHMB) is a ten-year periodic forest inventory for establishing business plan of forest utilization, which had to be done by Business Utilization Timber Forest Product in Natural Forest (IUPHHK-HA) and Plantation Forest (IUPHHK-HT) permit holders based on Government Regulation No. 6 of 2007. PT. Ratah Timber as a business license holder of Business Utilization Timber Forest Product in Natural Forest (IUPHHK-HA) requires preceding IHMB for establishing Ten-Years Natural Forest Business Plan for Timber Forest Product Utilization. IHMB with sampling concept reducing data measurement area to small certain surveyed area. Spatial distribution of timber potential from overall IHMB area, which in some compartment is not represented, may be estimated using spatial interpolation using GIS from data that obtained in survey plots. This research intend to estimate forest standing stock, establishing map of timber volume and tree profile, and analyzing forest timber potential in PT. Ratah Timber, East Kalimantan. IHMB tabular data processing shows that more that 60% of standing stock in PT. Ratah Timber belongs to Kayu Meranti (KM) class in all trees growing class (pole, small trees and large trees). Largest tree density is available at pole class by 206 poles/ha, meanwhile largest volume is available at large tree class by 146,73 m3/ha and overall standing quality is considered good based on its tree quality. IHMB spatial data distribution shows that PT. Ratah Timber has the largest area or compartments in lowest class potential. Spatial distribution map for large trees inform that largest compartment aggregated at 0-24 N/ha and 0-146.6 m3/ha in density and volume distribution classes. Potential analysis and tree spatial distribution overlay for 50 cm up commercial tree diameter shows normal standing structure condition, in spite of its potential condition was not too high, about 79,8% of PT. Ratah Timber area only having 0-28 trees/ha tree density with 0-279,6 m3/ha standing volume.

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….
