Judul: Spatial Modeling for Agroforestry Development at Panjalu District in Cimuntur Sub-Watershed, Ciamis
Abstrak: Kecamatan Panjalu berada pada wilayah hulu sub DAS Cimuntur. Sedangkan sub DAS Cimuntur merupakan bagian hulu dari DAS Citanduy. DAS Citanduy merupakan salah satu DAS dengan kondisi kritis di pulau Jawa. Lebih dari 50% luasan di sub DAS Cimuntur memiliki kemiringan lereng di atas 8% dan 73% dari total luas sub DAS Cimuntur memiliki tingkat erosi sangat tinggi. Hal tersebut menjadikan daerah ini rawan akan bencana. Tujuan dari penelitian ini adalah mengidentifikasi pola agroforestri yang sesuai dan diinginkan oleh masyarakat di Kecamatan Panjalu, membangun model spasial dan memetakan wilayah pengembangan agroforestri pada wilayah Kecamatan Panjalu di sub DAS Cimuntur Kabupaten Ciamis. Pola agroforestri yang sesuai dan diinginkan oleh masyarakat di Kecamatan Panjalu yaitu pola Manglid tumpangsari Kapulaga, Manglid tumpangsari Singkong, Sengon tumpangsari Kapulaga, Sengon tumpangsari Pisang, Sengon tumpangsari Singkong, Mahoni tumpangsari Singkong, Mahoni tumpangsari Kapulaga, Mahoni tumpangsari pisang, Sengon tumpangsari kopi dan Mahoni tumpangsari kopi. Model dibangun berdasarkan variabel dari multi kriteria atas penilaian expert judgment, sehingga masyarakat Panjalu tidak hanya sebagai penyedia informasi saja, tetapi juga sebagai pengambil keputusan. Model spasial untuk memetakan pola agroforestri di Kecamatan Panjalu yaitu 0,43 (0,09 skor X1 + 0,15 skor X2 + 0,21 skor X3 + 0,12 skor X4 + 0,32 skor X5 + 0,11 skor X6) + 0,35 (0,39 skor Y1 + 0,25 skor Y2 + 0,22 skor Y3 + 0,14 skor Y4) + 0,22 (0,45 skor Z1 + 0,35 skor Z2 + 0,19 skor Z3). Pengembangan pola agroforestri di Kecamatan Panjalu sub DAS Cimuntur dapat dipetakan dan dapat menekan tingkat erosi aktual sebelum diterapkannya pola agroforestri dari 170.955 ton/tahun menjadi 35.622 ton/tahun., Panjalu sub-district is in the upstream area of the Cimuntur sub-watershed. Meanwhile, the Cimuntur sub-watershed is the upstream part of the Citanduy watershed. The Citanduy watershed is one of the watersheds with critical conditions on the island of Java. More than 50% of the area in the Cimuntur sub-watershed has a slope of above 8% and 73% of the total area of the Cimuntur sub-watershed has a very high level of erosion. This makes it a disaster-prone area. The purpose of this research is to identify agroforestri patterns that are suitable and desired by the community in the Panjalu District, Cimuntur Subwatershed and to build a spatial management model based on site-level agroforestri pattern options, and map the site level agroforestri pattern in the Cimuntur subwatershed. Agroforestri options that are suitable and desired by the community in the Panjalu sub-district of the Cimuntur watershed are the options for Manglid with Kapulaga, Manglid with Cassava, Sengon with Kapulaga, Sengon with Banana, Sengon tumpangsari Cassava, Mahoni with Cassava, Mahoni with Kapulaga, Mahoni with Banana, Sengon with coffee and Mahoni with coffee. The model is built based on variables from multi criteria on expert judgment, so that the Panjalu community is not only a provider of information, but also as a decision maker. The spatial model for mapping agroforestri patterns at the site level in Panjalu District, Cimuntur sub-watershed, namely 0,43 (0,09 score X1 + 0,15 score X2 + 0,21 score X3 + 0,12 score X4 + 0,32 score X5 + 0,11 score X6)

Judul: Land use planning based on soil conservation: case study at the subwatershed of upper ciasem in the subang district
Abstrak: Subwatershed of Upper Ciasem is one of the important subwatershed in the Subang District due to its strategic role for rice field irrigation. The objectives of this research were to (1) evaluate existing land use based on land capability classification, (2) predict soil erosion using USLE formula and (3) set sustainable land use planning. The materials and equipments that were applied are existing land use map, soil map, slope class map, GPS, GIS, Clinometer, and Compass. The land characteristics data of this research are rainfall, soil physical characteristics, degree and length of slope, and land cover that were collected from each representative land unit. The research shows that dominant land use in the upper Ciasem subwatershed are rice field (33.95%), estate plantation (21.29%), mix garden (14.25%) and forest (13.35%), it indicates priority of economic scale. Land capability classification of recent land use, especially in dry land, mix garden and shrub in 15%-40% of slope are classified in class III and IV with slope as the limitation factor. Based on criteria of land capability classification, those land uses are suitable with its land capability, however, since slope as the limitation factor, soil conservation measures must be applied, such as strip cropping, contour cropping, contour ridges and furrows, and terrace. Soil erosion prediction on existing cropping pattern and land cover shows that generally soil erosion (A) is higher than tolerable soil loss (Atol) due to mainly slope factor and erosivity index (R). Thus, there should be an improvement of land use management by applying cropping pattern and agrotechnology properly. Farmers income from actual cropping pattern is not adequate to fulfil basic living requirement which is Rp 8.000.000 per household per annum, due to quite small farm size land without applying agrotechnology. In order to increase the farmers income, it is needed to improve cropping pattern and agrotechnology, aside from off farm income. In Regional and Arrangement Spatial Planning (RTRW), economic aspect has been still being the main consideration in the land use planning. In the long term of land use utilization, it is better to convert dry land and shrub into forest or mix garden. The direction of regional planning of upper Ciasem subwatershed is better to be oriented in developing of tourism, especially agrotourism and ecotourism.

Judul: Pengujian Virus Newcastle Disease Gen VII Isolat Lapang Sebagai Virus Standar Pada Uji Tantang Vaksin
Abstrak: This study was conducted to determine the standard of Newcastle disease virus Gene VII field isolate as a virus challenge to vaccine test. A virus suspension that has previously been tested by HA test then titrated with EID50 using 30 Specific Pathogen Free (SPF) of 10 day old chicken embryonated eggs. In addition, chicken lethal dose50 (CLD50) test were used to determine the virus titer that could cause 50% death of the chicken population. The CLD50 test was used 25 day-old-chickens (DOC) divided into 5 groups. The virus was diluted from 10-1 to 10-8. The 104 to 10-8 dilution of NDV was infected to every group of chicken via eyedrop and intranasal with 0.1 ml/chicken dosage. Haemagglutination test showed that the allantoic fluid were contain high titers of NDV is 512 HAU. The infective NDV that had been titrated by EID50 test showed the virus titers is 109 EID50/0.1 ml or 1010 EID50/ml and the virus titers of CLD50 test e.i 106.48 CLD50/0.1 ml or 107.48 CLD50/ml. These results can be concluded that the NDV Gene VII field isolates were most appropriate to be used as a standard virus to vaccine test
