Judul: Analisis Perubahan Penggunaan Lahan, Pola Ruang dan Tingkat Perkembangan Wilayah di Kota Bogor
Abstrak: Bogor City is located 60 kms from the Indonesian Capital Jakarta and 120 kms from Bandung the capital of West Java Province. Strategic agricultural land and inexpensive land price have encouraged stakeholders to invest in agricultural sector and also non agricultural sector. Land use conversion is inevitable, although the goverment has set up the regulation to control land usage (Act No 26 year 2007). This research are conducted: (1) To analyze existing land use of Bogor City (land use in 2014). (2) To analyze the land use change in period of 2005-2012. (3) To analyze the consistency of existing land use compare to land allocation in the RTRW of Bogor City. (4) To identify regional development hierarchy level in Bogor City. (5) To determine factors that influencing land use change. This research was started with land usage map designing which retrieved from digitized result on administrative map 1: 5000 scales to ikonos image of Bogor City in years of 2005 and 2012. Consistency and inconsistency is obtained by overlaying land use map in 2012 and land allocation map of Bogor City years 2011-2031 (RTRW map). PODES is used to determine the regional hierarchy level by multiple regression method. Existing land use classified into 9 land use, in sequence from the largest one are: mixed garden, non-wellarrang ed settlement, paddy field, well arranged settlement, trade area, water body, dryland farm, open field and goverment office area. Dryland farm land use changes into 2 land use, open field land use change into 6 land use and paddy field land use change into 6 land use. The consistent existing land use compare to RTRW is 40.95% while inconsistence existing land use is 59.05%. During period of 2006 to 2012, most of regional development hierarchy in Bogor City are the relative constant hierarchy (42 villages/61.8%). 12 villages (17.6%) are increase in the hierarchy whilst 14 villages (20.6%) are decrease in the hierarchy. Factors that influencing land use change of Bogor City in period of 2005-2012 are: area of agricultural land in the years of 2005, social facilities growth, and economy facilities growth

Judul: Pertahanan pada ikan terhadap infestasi ichthyophthirius multifiliis dengan tetrahymena pyriformis dan tetrahymena thermophila
Abstrak: Ichthyophthirius multifiliis adalah protozoa dari kelas Oligohymenophorea, ordo Hymenostomatida dan famili Ophryoglenidae. Protozoa ini sering menyerang ikan liar, ikan yang dibudidayakan dan ikan hias dalam akuarium. Bentuk dewasanya (trophozoit) tinggal dibawah kulit ikan yang menjadi inangnya. Mereka makan runtuhan sel dan mengelupaskan epithel. Angka mortalitas dapat mencapai 100% pada ikan yang dipelihara dalam akuarium. Penyakit ini telah dilaporkan dari semua benua. Banyak preparat kimia yang dapat dipakai untuk mengontrol parasit ini. Yang paling berhasil dari antara preparat-preparat kimia yang digunakan adalah malachite green dengan konsentrasi 0.25 ppm yang dibiarkan bekerja selama 1 jam. Namun ada masalah yang timbul dalam pengobatan, karena di dalam hampir setiap perairan terdapat parasit tersebut. Hal ini menyebabkan sewaktu-waktu atau secara kontinyu terjadi infestasi oleh parasit ini dalam populasi ikan. Untuk mengatasi masalah ini maka tindakan yang dianggap praktis dan efektif untuk mengontrol parasit ini adalah imunisasi. Disinipun timbul permasalahan pula. Karena Ichthyophthirius multifiliis adalah parasit obligat, maka sulit mengumpulkannya dalam jumlah yang cukup untuk pembu- atan vaksin. Maka dicari sumber lain untuk membuat vaksin terhadap parasit ini. Hasil penelitian menunjukan bahwa Tetrahymena pyriformis dan Tetrahymena thermophila dapat dipakai sebagai vaksin terhadap Ichthyophthirius multifiliis. Masalah yang timbul kemudian adalah bahwa perlindungan terhadap Ichthyophthirius multifiliis ternyata tergantung pada strain (galur) atau isolat dari kedua spesies Tetrahymena di atas yang digunakan. Sebagai pertahanan bentuk lain dari ikan selain imunitas dapat dikemukakan ketahanan non imunologis yang tergantung pada spesies ikan dan kenaikan kadar vitamin C didalam makanan.
