Judul: Monitoring Perubahan Lahan Menggunakan Citra Satelit Multiwaktu di DAS Citarum Hulu, Jawa Barat
Abstrak: Fungsi dan peranan Daerah Aliran Sungai (DAS) Citarum, khususnya Citarum hulu sangat penting dalam menguasai hajat hidup orang banyak. Di wilayah ini terdapat banyak sarana yang sangat penting, mulai dari bendungan Saguling untuk kepentingan pembangkit tenaga listrik, Kota Banduny sebagai pusat pemerintahan, pemukiman, industri, pendidikan dan pengembanyan lainnya. Seluruh aktivitas tersebut erat kaitannya dengan keutuhan dan keseimbangan kondisi fisik DAS yany perlu dikelola agar asas pembangunan berkesinambungan yang peduli lingkungan dapat dilaksanakan. Namun fakta sekarang menunjukkan bahwa kondisi fisik dan lingkungan di d a e ~ lin i inulai niemprihatinkan, khususnya banyaknya perubahan fungsi lahan yang tidak sesuai dengan peruntukannya. Sebagai contoh adanya perubahan dari jenis penutupan dan penggunaan lahan hutan atau bervegetasi menjadi kawasan terbangun. Perubahan-perubahan ini perlu diketahui atau dimonitor guna menentukan kebijakan yang tepat. Dengan selalu memonitor perubahan lahan hutan, dapat melnbantu lnenentukan langkah-langkah tepat dalam lnenanggulangi kerusakan llutan. Guna mendukung ha1 tersebut, pemanfaatan teknologi penginderaan jauh merupakan alrernatif yang sangat baik terutama pengindraan jauh satelit. Landsat TM-5 adalah citra penginderaan jauli yany digunakan dalam penelitian.

Judul: Perubahan Penutupan Lahan di DAS Citarum Hulu – Jawa Barat dengan Menggunakan Citra Satelit LANDSAT ETM+
Abstrak: Citarum Hulu watershed has an important function for the people such as, the hydroelectric power, agricultural irrigation, industry, and tourism for the people of West Java. Population growth and industrial development resulted in increasing the need for land. Utilization of land resources for development activities are affecting changes on forests and water catchment areas. The decreasing of forest has resulted in flood, reduced groundwater discharge, and increased critical areas. LANDSAT satellite is one of the satellites that can be used to monitor land cover and land use changes using instrument ETM+ (Enhanced Thematic Mapper) so we will know the land changes that occur in the Citarum Hulu watershed. This study aims to analyze the land cover and land use changes on forest cover particulary in Citarum Hulu watershed, West Java in years of 2001, 2006, and 2011 by using data satellite LANDSAT ETM+ image spatial resolution 30 m. The method used is the initial processing of the image, visual image interpretation, field observations, the determination of sample area, analysis contingency with transformed divergence method, supervised classification using the maximum likelihood method, analysis of accuracy test, reclassification, and analysis of land cover change. Land cover and land use of Citarum Hulu watershed can be classified into 12 classes of land cover and use, namely primary forest, secondary forest, plantations forest, scrub, farm, settlement, open land, dry land agriculture, mixed dry land agriculture, paddy fields and airport. In 2001, primary forest of Citarum Hulu watershed reaches down to 1.682,22 ha and 1.036,61 ha or about 0.28% in 2006. At the same time, the class of settlement increased from 38.807 ha in 2001 to 41.367,40 ha in 2006. Forest converted to rice fields, dry land agriculture, plantations forest, farm, and mixed dry land agriculture. Class open land has decreased in the period 2001-2011, amounting to 1241.10 ha or 0.534%. Decrease the amount of open land class area of land shown on Citarum Hulu watershed increasingly used by the public.

Judul: Gambaran respon kebal terhadap newcastle disease (ND) pada ayam pedaging yang di vaksin IBD-Killed setenagh dosis
Abstrak: This research aimed at learning immune response of againts Newcastle Disease (ND) on broiler were given half dose IBD-killed vaccine. Two hundred day-old broiler chicks where randomly divided into four groups of 50 chicks each. Before being divided, 25 chicks was taken their blood to know maternal antibodies titer against ND. On the 4'" day chicken groups P1 and P2 was vaccinated with ND active vaccine and ITA ND+IBD half dose inactive vaccine. The P3 and P4 chicken groups were vaccinated with ND active vaccine and ND inactive vaccine on the same day. The repeated ND active vaccination was given to all group on the 2Sth day. The against IBD challenge test was can-ied out on the 14"' day in the group PI and P3. Sample of blood was taken on the 1411', 21S', 2Sti', and 42"d day. Titer antibodies against ND observation were done with haemaglutination inhibition test against all the sample of senun. Results of the research showed that effect of iinuilosupresion happened to the group that was challenged by the IBD vims in the 1'' and 2"* week post infection. Four weeks after test, titer antibodies of groups that vaccinated ITA ND+IBD half dose inactive vaccine could increase, whereas the group that not vaccinated stayed low. Based on this research, showed that the vaccination of IBD-killed half dose could not protect the chicken towards effect immunosupresion up until two weeks after infection.
