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: Optimasi alokasi lahan perkebunan menggunakan pendekatan multi kriteria spasial berbasis metode kontinyu
Abstrak: The proficient planning of land resource becomes a major issue for rural development in Indonesia. It endorses to estimate the capacity of land employing evaluation method. Land evaluation is carried out to estimate the suitability of land for a particular usage. However, conventional Boolean which is generally used for assessing land suitability ignores the continuous nature of soil landscape variation that can misclassify of a current site. The research objective is to apply fuzzy theory of land suitability evaluation for plantation commodity. By means of multi-criteria decision making (MCDM), the fuzzification conducted by weighing of numerous criteria using Analytical Hierarchy Process. Improving spatial allocation model will have influential meaning for a management of land. Land allocation in rural region requires the compromise between ecological condition, socio-economic development, and infrastructure availability. Using compromise programming (CP) and fuzzy set approach within a geographical information systems (GIS) environment, numerous decision criteria have been developed. Decision criteria consist of road accessibility, market distance, electrical energy, settlement distance, commodity preference of people, and land suitability. Suitable land allocation for plantation commodity is 28,650 hectares which consists of 2,702 hectares dry land forest, 21,937 hectares of dry land farming, 3,992 hectares of shrubs, and 18 hectares of open land.

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.
