Judul: Audit Tata Ruang Desa Tugu Utara dan Desa Tugu Selatan Kawasan Puncak
Abstrak: Tugu Utara Village and Tugu Selatan village are part of the upstream Ciliwung watershed that located in Puncak area. Intensive development in the upstream of Ciliwung watershed that are inconsistent with the spatial planning regulation resulted in environmental degradation. This research was conducted with the aims to (1) identify the spatial patterns of Bogor District Spatial Plan 2005-2025, status of forest area, land capability class and actual land use in Tugu Utara Village and Tugu Selatan Village; and (2) analyze the inconsistencies between the actual land use and the ideal criteria of land use allocation. Dominant land use in Tugu Utara village is a tea plantation (area of 36% of the village), while the dominant land use in Tugu Selatan village is a forest (area of 60% of the village). Inconsistency of the actual land use according to the allocation based on Bogor District Spatial Plan 2005-2025 found in protected forest areas with actual land use as a tea plantation with an area of 580 ha.

Judul: Penggunaan Lahan Dan Nilai Sewa Lahan (Land Rent) Di Kawasan Puncak; Studi Kasus Desa Tugu Utara Kecamatan Cisarua Kabupaten Bogor
Abstrak: Desa Tugu Utara merupakan salah satu desa yang berbatasan langsung dengan kawasan hutan di Puncak Bogor, dan dalam Rencana Tata Ruang (RTRW) Kabupaten Bogor berada dalam kawasan hutan lindung. Keindahan alam di Desa Tugu Utara mendorong berbagai pihak untuk membuka lahan terbangun seperti villa, hotel dan lain sebagainya yang mengakibatkan terjadinya konversi lahan, area hutan dan penggunaan lahan pertanian menjadi lahan non pertanian. Penelitian ini dilakukan dengan tujuan untuk: (1) mengidentifikasi tipe-tipe penggunaan lahan di Desa Tugu Utara, (2) mengidentifikasi pola distribusi spasial inkonsistensi pemanfaatan lahan di Desa Tugu Utara saat ini (eksisting) terhadap Rencana Tata Ruang Wilayah, dan (3) menghitung nilai land rent pada setiap penggunaan lahan. Penggunaan lahan dominan di Desa Tugu Utara yaitu kebun teh berkerapatan tinggi seluas 364,3 ha. Luas terendah yaitu sawah dan semak belukar. Luas semak belukar sebesar 5,4 ha dan sawah sebesar 7,5 ha. Luas inkonsistensi terbesar yaitu kawasan hutan lindung menjadi penggunaan lahan aktual kebun teh berkerapatan tinggi seluas 364,3 ha. Nilai land rent tertinggi yaitu penggunaan lahan aktual perumahan penduduk padat sebesar 165.233 Rp/m2/tahun, sedangkan nilai land rent terendah yaitu penggunaan lahan aktual sawah dengan nilai sebesar 219 Rp/m2/tahun.

Judul: Antibody Responses against Newcastle Disease and Evaluation of Infectious Bronchitis Maternal Derived Antibody on Vaccinated Layers.
Abstrak: Information of maternal derived antibody (MDA) and onset of immunity after vaccination is important to determine appropriate vaccination programme of chickens. The aim of this study was to evaluate duration of Infectious Bronchitis (IB) MDA and evaluate onset of immunity Newcastle Disease (ND) vaccination among layers. All layers were vaccinated using live ND and Infectious Bursal Disease (IBD) at one day old age, and received Avian Rhinotracheitis (AR) vaccine at 4 day old age. Serum samples were collected at various ages: 7, 10, 14, 20, 22, 24, 29 and 35 day old. The presence of ND antibodies was measured by the hemagglutination inhibition (HI) test, whilst the presence of IB antibodies was measured by enzyme-linked immunosorbent assay (ELISA). Our study showed that ND antibodies were at positive level until 24 day old age, and reached protective level ≥ 25 only at 7 day old age, whilst IB MDA were positive up to 17 day old age. This result indicating the needs of ND booster vaccination at least at 24 day old and IB vaccination at 17 day old age.
