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: Evaluation of Influenza Antibody Titers in Serum and Egg Yolk of Layers Vaccinated with Influenza Vaccines.
Abstrak: Influenza belongs to the Orthomyxoviridae family which causes upper and lower respiratory tract infection. The aim of this study was to evaluate influenza-A specific antibody titers from serum and egg yolk of hens vaccinated with quadrivalent influenza vaccines. Three Hy-line Brown layers were vaccinated with quadrivalent influenza type A and B inactivated vaccines. Vaccination was carried out three times at a dose of 0.25 ml/chicken via the intramuscular route. The first vaccination was carried out at 24 weeks of age, then boosters were performed at 28 and 32 weeks of age. Serum and egg yolk were collected every week for 20 weeks since the first vaccination. Influenza A H3N2 and H1N1 antibody titers were determined using hemagglutination-inhibition (HI) test and agar-gel-precipitation (AGP) test. Influenza-A H3N2 and H1N1 specific antibodies were detected in both serum and egg yolk from the first to twenty weeks after the initial vaccination. Highest HI geometric mean titer (GMT) of H1N1 antibody reached 26.67 HIU at nine weeks post first vaccination (p.f.v), while H3N2 antibody reached 26 HIU at six weeks p.f.v. Our result showed that influenza antibodies can be produced in layers using quadrivalent vaccines and layer chickens are able to produce equivalent antibody levels for each influenza subtype.
