Judul: Land Evaluation to Support Land Use Planning using Geographic Information Systems and Goal Programming (A Case Study of Depok Municipality, West Java Province)
Abstrak: Land evaluation is an important part in the land use planning process. It assesses the suitability of land for specified land uses based on matching the qualities of different land units in a specific area, with the requirements of potential land use. The result of the evaluation is classification of land suitability for specific land uses. The research aims: 1) to analyze the land use based on land suitability for paddy field, dry land cultivation and protected area; 2) to arrange the optimization model for land utilization by considering the socioeconomic and environmental aspects; and 3) to determine the allocation of land utilization for paddy field, dry land cultivation and protected area. Integration between Geographic Information Systems (GIS) and Goal Programming (GP) to conduct land evaluation with a view to generate recommendation for optimal land allocation considering the socio-economic and environmental goals. The result of land suitability analysis showed that most of land is suitable for paddy field and dry land cultivation. Only a few of the existing areas was cultivated on land under poorly suitable class, i.e. around 0.05% and 0.15% for paddy field and dry land cultivation, respectively. The rest is cultivated on S1 (highly suitable) and S2 (moderate suitable). The mapping using GIS analysis showed that the protected area should cover 2,097.50 Ha of which about 621.35 Ha has been converted for settlement and industries. Optimizing land utilization was carried out by integrating economic, social (employment), and environmental (ecological) goals through multi-objectives of optimization method. Goal Programming (GP) can be used to optimize the available land resources to achieve these goals. Optimal land utilization in this study using GP increased the total areas of paddy fields and dry land cultivation categorized as cultivated areas. The total cultivated areas increased from the existing condition of 4,843.63 Ha to 4,854.42 Ha. The land allocation for paddy field and dry land cultivation according to GP would increase land productivity and labour input. The value of land productivity would increase to Rp. 30,811,129,271 per year from the yearly target of Rp. 30,811,103,144 per year, while labour input increased from the target of 1,478,966 workdays per year to 1,486,179 workdays per year. The increase of cultivated agriculture area was extended to the existing bare land or grass land which belonging to the S1 or S2 of the land suitability class and should not be categorized as protected area. The total land allocation for protected area is about 1,476.15 Ha.

Judul: Studi Perencanaan Pengelolaan DAS dengan Model Optimasi Penggunaan Lahan di Bagian Hulu DAS Mahakam
Abstrak: Land use which is not in accordance with the land capability, will cause land degradation. In Indonesia, there is progressive increase of critical land area size, every year, and this exerts an impact toward watershed damage. Objectives which are sought in the planning of watershed management often negate each other because from one point of view, there is a desire to maintain natural resources sustainability, and from other (economic) point of view, there is a desire to increase farmer's income. In order to obtain a model for planning sustainable watershed management, land use optiminazation was conducted and designed using the analysis of Linear Goals Programming (L GP) The study area had the size of 29 686 ha, comprising 3 subdistricts (namely Damai, Barong Tongkok and Melak) that were situated in the district of Kutai Barat, the province of East Kalimantan. The formulation of model for land use optimization was designed to achieve four targets, namely peak discharge. reduced rate of erosion (so that it is equal with or smaller than the targeted discharge and tolerable soil loss), ability of each farmer family to fulfill the need for food and rice, and ability of on farm income to create appropriate level of welfare. Research unit was homogeneous land unit. Data source for model input came from improvement of cropping pattern and alternative agrotechnology which was conducted by using simulation of CP factor. Data processing and analysis used the method of SCS, USLE and farm analysis. On the other hand, the completion of model used software General Algebraic Modeling System (GAMS) and Arcview 3,2. Land use with existing cropping pattern gave peak discharge of 116.39 m3/seconcj, erosion between 157-876 tonlha, production of upland rice 1.52 ton GKPlhalyear, and income Rp 3 268 636,-halyear. On the other hand, optimum land use pattern from the six scenarios model, showed better results as compared with the existing condition because ecologically, the land use could maintain the stability of peak discharge, and reduce erosion to the level below the targeted value. Although scenario model la and llla (with land use composition in the form of non irrigated rice field and dry land crop field) gave better result than those of existing conditions, but the occurring erosion were still higher than those in scenario model I, 11, Ill, and IV (with land use composition in the form of non irrigated rice field, dry land crop field, and estate field). This was because the priority for achieving erosion target in scenario la and llla was only up to the tolerable rate of soil erosion. Testing of scenario model I, 11, Ill, and IV showed that there was a tendency for increasing proportion of dry land crop field area size, but on the other hand, decreasing proportion of non irrigated rice field and estate field area size, if the target of achieving living standard is continuously increased. Spatially, recommendation that could be given for /and units of non irrigated rice field, dry land crop field and estate field is in the form of cropping pattern and agrotechnology LI *, L3b* ,

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.
