Judul: Analysis of Development Plan of Primary Center Gedebage in Bandung City Economic Development by Dynamic Systems Approach
Abstrak: Gedebage region as an area to be developed has limitations because it includes areas that have many short comings such as lack of infrastructure and unstable soil conditions. Therefore, in the development of the Gedebage area, the system design is required in the form of engineering assessment of the performance indicators of regional development based on dynamic systems approach based on the principle of feedback between the subsystem, subsystem of the population, and economic subsystem. The purpose of this study was to analyze the Gedebage regional development plan especially Primary Center Gedebage in economic development of Bandung. This research use data analysis through modeling system that includes the land use in the region Gedebage, various economic activities and population dynamics. The research result suggests that the development of the Primary Center Gedebage as planned, will encourage the economic development of Bandung city in a positive direction.

Judul: Penentuan prioritas pembangunan berdasarkan potensi dan tingkat perkembangan kecamatan di kota Depok
Abstrak: A Priority Setting of Development is related to Potential and Actual Development Level. Depok City, as hinterland of Jakarta, has high impact of suburbanization where some areas has being converted into some building areas such as industry, trading, and property. Process of urban sprawl is getting worse, and feared it would be come “a waste” of Jakarta development as the impact of crossings and residential location for commuters. Therefore we need to know the development characteristic of Depok City in Jabodetabek Metropolitan Area as macro level, Depok City itself as meso level, and the potential and actual development of each sub-district level. Analysing development characteristic for each level would be conducted by using LQ, SSA, Skalogram, Index Entropy, and PCA analysis. The result showed in macro level, Depok City has a potential sector in the industrial, electricity-gas-water, and trade sector, in meso level, Depok City development policy focus on trade and services sector by considering a sustainable environmental support, though in micro level, each sub-district has various potential sector, such as industry in Sawangan; elctricity-gas-water, industry, and transportation in Pancoran Mas; services and industry in Sukmajaya; industry and trade in Cimanggis, agriculture and construction in Beji, the mining and quarrying, electricity-gas-water, transportation, and financial center in Limo. Whereas based on the actual development by using the PCA analysis, we got three regional typologies such as CBD Region, Under-develop Region, and Residential Region. Pancoran Mas, Sukmajaya and Beji are included in the CBD Region; Sawangan, Beji and Pancoran Mas are included in Under-developed Region; Pancoran Mas, Limo, and Beji are included in the Residential Region. Based on potential sector and regional typology, it can be formulated what became the priority of development in each sub-district, such as agroindustry development in Sawangan and Cimanggis, improvement services function centre of electricity-gas-water in Pancoran Mas, controlling spatial activities in Sukmajaya, strenghtening urban agriculture in Beji, and controlling bussiness property activities in Limo.

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.
