Judul: Model Simulasi Pengelolaan Hutan Berbasis Karbon (Studi Kasus di IUPHHK PT. Mamberamo Alasmandiri, Kabupaten Mamberamo Raya, Provinsi Papua)
Abstrak: In order to fullfilling market demand of wood which still increasing and to support government commitment on global emission reduction effort, there should be a simulation to determine good formula on forest management. This formula applied when forest moratorium occur in Indonesia. The study simulating some forest management scenario’s by considering another benefits of forest wood, because wood, carbon and non timber forest products has a high market demand nowadays. The scenario’s include forest management with TPTI system, carbon based forest management system, combination system between carbon based and ants nest scenario, carbon based and mace oil combination management scenario, and carbon based and sago utilization management scenario. A proper forest management could give a good economic, ecology and social benefit. The scenario of simulation results a value of business feasibility on each scenarios, has a positive value of net present value (NPV), benefit cost ratio (BCR) more than 1 and internal rate of return more than interest rate used. This means each scenario of business is feasible. The highest value of NPV, BCR and IRR is on carbon combination forest management and sagoo utilization, by value NPV of Rp. 25.170.588,59. This value indicates the cost used on forest management giving benefit during financial analysis time, which is 5 based on present value. BCR value of carbon based and sago utilization scenario is 1.47 This condition illustrates benefit obtained as much as BCR during project time, is bigger than the cost issued. Meanwhile the IRR value of carbon based and sago utilization scenario is 28% above bank rate is 10%, this value indicates the good criteria of business feasibility based on financial is combination carbon based and sago utilization forest management. This is also supported by a good level of sustainability of standing stock on next harvest cycle, due to banned wood utilization and turn to carbon sequestration service utilization.

Judul: Pemodelan Simulasi Pengelolaan Hutan Alam di PT Suka Jaya Makmur
Abstrak: Forest product is consists of timber, non-timber forest products and environmental services. Currently, utilization of forest resources in the PT Suka Jaya Makmur is only focusing on timber utilization, while the non-timber forest products is one of potential forest product that increase company's revenue and the welfare of community around forest. The purpose of this research is to make simulation model of timber product management and non-timber forest product utilization is not the time to predict the revenue of company and community with a variety of forest management scenarios. Simulation modeling in this study is using system modeling approach. System modeling is using complex component from the real world and it is simplified so that it can be modeled for a particular purpose. Based on the simulation results, the best scenario is scenario modeling 3 because it produces the greatest revenue. Scenario 3 about the company is managing timber and non-timber forest products as well as a community as worker. Income is earned by the company until the end of the concession period in 2054 if managing timber and non-timber is Rp 447 614 560 712 while the community revenue is Rp 180 852 937 with the average income/family is Rp 10 114 117/year.

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….
