Judul: Desain Taman Cilaki Atas Kota Bandung Berbasis Ekologi
Abstrak: Urban park is a green open space which accomodate social activities needs. Aesthetic and ecological space are another function of urban park. Bandung is one of many cities which have many urban parks, with the potency to provide an ecological balance in the city. However, urban parks of which are available in most cases created simply for beautification and social function, while the other function is still can be maximized. The function of urban parks that are often forgotten is the controller of ecological balance. Upper Cilaki Bandung Urban Park is one of it. Urban park which maximizing ecological function and understanding the ecological characteristics of the landscape is needed. One of the ecological aspects which are becoming main point in park issues is the hydrological aspect. The characteristics of park topography which is relatively steep, causing many topsoil removal. A descriptive analysis was carried out to determine the physical characteristics and the design of the park. The purpose of this research is to identify and analyze the user's characteristics of urban park to find out the needs and expectations of users especially for ecological sustainability of the environment. Then, the functional, aesthetic, and ecologic urban park design will be produced. The basic concepts used are eco urban park. In the design process, it is important to note the recreation and ecological aspects. Ecology which is mentioned here cover a natural environmental cycle and preservation of local culture. The design concept applying nervous patterns to create the feel of the city. These patterns become the focal point that breaks down the natural impression of the park. Seven retention ponds which are connected with bioswale built to support the ecological function. The pond will maximize the infiltration of water run off cached as well as irrigation needs. This research is expected to be a consideration and guidelines in designing the urban parks based on ecology.

Judul: Eco-Design of Merdeka Park as an Alternative to the Development of Urban Green Open Space
Abstrak: Taman Merdeka berperan penting secara sosial dan ekologis di tengah padatnya Kecamatan Sukmajaya. Taman ini membutuhkan desain yang mampu menyediakan ruang yang indah dan memenuhi kebutuhan pengunjung tanpa mengesampingkan fungsi ekologisnya. Dengan demikian, desain Taman Merdeka perlu dilakukan dengan pendekatan desain ekologis yang mengurangi dampak negatif terhadap lingkungan. Penelitian ini bertujuan mengidentifikasi dan menganalisis kondisi existing tapak, menyusun konsep desain ekologis Taman Merdeka, dan mendesain secara ekologis Taman Merdeka Depok yang indah, fungsional, dan ramah lingkungan. Penelitian ini dilaksanakan menggunakan metode deskriptif melalui empat tahap yang mencakup persiapan, inventarisasi, analisis dan sintesis, dan desain dengan pendekatan fisik dan biofisik, sosial, dan desain ekologis. Konsep dasar dari desain ekologis Taman Merdeka adalah Urban Eco-Excursion yang berarti sebuah ruang terbuka hijau yang mampu mengintegrasikan berbagai kegiatan, untuk berbagai kelompok, dengan pendekatan yang ramah lingkungan. Konsep desain dikembangkan dari motif Batik Depok. Desain ekologis diterapkan melalui penggunaan green infrastructure untuk stormwater infiltration and cleaning, konservasi vegetasi eksisting, upcycling center untuk pengelolaan sampah, dan penggunaan bahan yang ramah lingkungan. Desain taman mencakup bioswales, stormwater wet pond, lapangan-lapangan olahraga, playground, plaza, area pujasera, upcycling center, welcome area, area duduk, elevated walkway, amphitheatre, lawn, promenade, dan toilet., Merdeka Park plays important social and ecological roles in the midst of the very dense Sukmajaya District. This park needs a design that is able to provide an aesthetically pleasing space and meet the needs of visitors without neglecting ecological functions. Thus, the design of Merdeka Park needs to be done with an ecological design approach that minimizes the impacts that may damage the environment. This study aims to identify and analyze the existing site conditions, create an ecological design concept of Merdeka Park, and ecologically design Merdeka Park that is beautiful, functional, and environmentally friendly. This study was conducted using descriptive method through four stages which are preparation, inventory, analysis and synthesis, and design with a physical and biophysical, social, and ecological approaches. The basic concept for the eco-design of Merdeka Park is Urban Eco-Excursion which means a green open space that integrates various activities for various groups with an environmentally friendly approach. The design concept is inspired by Depok's Batik. Eco-design is implemented through the use of green infrastructure for stormwater infiltration and cleaning, conservation of existing vegetation, upcycling center for waste management, and environmentally-friendly materials. The design of the park include bioswales, stormwater wet pond, sports fields, playground, plaza, food court, upcycling center, welcome area, seating areas, elevated walkway, amphitheatre, lawn, promenade, and toilet.

Judul: Co-infection of Infectious Myonecrosis Virus (IMNV) and Vibrio harveyi in Pacific White Shrimp (Litopenaeus vannamei)
Abstrak: L. vannamei production in Indonesia was growing intensively. In 2006, IMN (infectious myonecrosis) disease was confirmed spread to Indonesia shrimp farm and declined shrimp production. The study was conducted to investigate effect of dose of V. harveyi on co-infection with IMNV in L. vannamei as well as development of viral infection. Shrimps juvenile were oral infected with IMNV infected shrimps 10 % feeding rate during 3 days and co-infected with 106, 107 and 108 cfu/ml V. harveyi. Mortality rate was 0 % in control and single infection of V. harveyi except 108 cfu/ml treatment. Mortality pattern demonstrated on co-infection was faster and higher than single IMNV infection in 14 days observation. The density of green colony Vibrio in hepatopancreas of co-infected shrimps collected in 2, 4, 6, 8 and 10 days post infection were higher than V. harveyi single infected (significantly in 10 days post infection). There were no difference of IMN disease development between co-infection and IMNV single infection. It was confirmed by visual gross sign appeared, tissue and lymphoid organ histophatology, organ abnormality, and PCR test. In conclusion, IMN disease caused higher and faster mortality on co-infection with V. harveyi, but not affect to IMN disease development.
