Judul: Model konservasi sumber daya air Danau Toba
Abstrak: This study aims to design build water resource conservation model with emphasis on the technical study of the socio-economic aspects of ecological aspects involving extensive changes in land use, population growth, continuity of operation of the hydropower Asahan and some other aspects of the outer catchment. In general, intended to illustrate the balance ofthe water balance under the influence of land use and other economic activities. Analysis of water balance was constructed by the method of modeling dynamic system sthat are supported by Powersim software, where the method of using water availability FJ.Mock method with variables derived from the analysis of the ecological condition of the catchment area of Lake Toba. Then performed simulations of water balance and water level for the condition without intervention variables and intervention variables. Where the intervention variables performed pessimistic scenario, moderat and optimistic to provide an overview of conservation policy. From the simulation results on the balance of water and the lake water level was found in 2017 and the year 2057 the best scenario is between moderate and optimistic scenarios where the population growth of between 0.8% - 1.0% per year, infiltration coefficient values between 0.40 to 0.45, the value land cover factor between 0.25 to 0.3 while the flow of water being released into the Asahan River is 91,69 m3/sec in average.

Judul: Pemodelan Kebutuhan Air dan Ketersediaan Air Tanah di Pulau Tidore
Abstrak: limited catchment area and raw water sources Small island has specific characteristics limited catchment area and vulnerable to the sea water intrusion. Tidore Island is a small island that has 117,6 Km² and amount people 54 763. Annual of population growth, commercial facilities, and public facilities will increase the demand for raw water. The objectives of this study are (1) to identify the water demand and groundwater availability , (2) to build a model of water demand and groundwater availability , and (3) to formulate groundwater policies. Survey method was used to assess requared at the study area for about 71 sampling sites of will. The data result was analyzed by using the dynamic system analysis to determine the domestic water demand and non domestic demand modeling was developed using Stella version 9.0.2. The results of the analysis showed, that in 2009, the water demand of the existing population was 2 121 124.50 m3/year, the water demand of public facilities was 101 184.35 m3/year, and commercial facilities was 62 523.04 m3/year which made the total of water demand was 2 284 831.89 m3/year. While in 2033, the water demand projection on Tidore Island would be 3 181 713.17 m3/year, the water demand of public facilities would be 150 764.62 m3/year, the water demand for commercial facilities would be 400 814.17 m3/year, which made the total of water needs would become 3 735 291.97 m3/year. As for the groundwater availability in 2009 was about 2 850 000 m3/year and the projected groundwater availability in 2033 would increase into 2 856 117.14 m3/year. To increase the groundwater availability, conservation act toward every type of land use is needed. Those conservation efforts can be included reforestation, terracing and infiltration wells. The result of simulation model has obtained a scenario of an integrated policy (saving and conservation) that can reduce water consumption and increase the groundwater availability

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
