Judul: Model Simulasi Pengelolaan Hutan di Kesatuan Pemangkuan Hutan (KPH) Bogor
Abstrak: Optimal forest management was very important for Forest Management Unit (FMU) Bogor to create sustainability of economic, ecological and social. The point of this research was getting the best simulation of forest management in order to improve welfare of the environment in KPH Bogor, especially to increase in revenue in KPH Bogor. Analysis performed for the management was system approach,it used because of the complexity of the data. Forest management in KPH Bogor was travel management , forest village institutions (LMDH), resin management , timber management, non-timber forest products management and carbon trading. Analysis was done by creating a model that can represent the current forest management. The model has been created then performed various scenarios in order to get the best results. The results showed that the scenario of KPH Bogor by using a combination of KPH current management, non-timber forest products (NTFPs) and carbon trading was the best scenario.

Judul: Model Simulasi Pengelolaan Hutan di KPH Bojonegoro Perum Perhutani Divisi Regional II Jawa Timur
Abstrak: Forest management simulation model in KPH Bojonegoro is an activity to make a model of forest products management both timber and non-timber has been developed by using several scenarios with the hopes of increasing revenue KPH Bojonegoro with a period of 2012 to 2021. This research was proposed to arrange and to make forest management simulation model and also to determine the best forest management in KPH Bojonegoro trough making some forest product scenario. In making the simulation model, it needs modeling software called Stella 9.02 and Microsoft Excel 2010. The results of this research shows that forest management scenario which only utilized timber apparently produced the lowest value of NPV Rp694 361 428 and BCR 1.12 (skenario I), where as forest management scenario that have the largest NPV value is timber forest management products scenario, non-timber forest products and environmental services with a value of NPV Rp 6 849 280 600 and BCR 1.28 (scenario IV) .

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….
