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: Design of Amri Yahya Park Kayuagung Ogan Komering Ilir South Sumatera Based on Ecodesign Concept
Abstrak: Taman Amri Yahya sebagai taman kota memiliki lokasi yang strategis dan potensial tetapi belum memiliki pola desain dan konsep fungsional yang jelas. Permasalahan yang ditemukan yakni penataan tanaman yang kurang tertata, kurangnya pemeliharaan softscape dan hardscape, dan pola desain lanskap yang kurang jelas sehingga kualitas visual lanskap menurun. Penelitian ini bertujuan mengidentifikasi dan menganalisis kualitas desain dan fungsi berdasarkan potensi dan kendala pada Taman Amri Yahya, menganalisis persepsi dan preferensi masyarakat terhadap kondisi Taman Amri Yahya sebagai sumber acuan pada proses desain, dan membuat usulan desain Taman Amri Yahya berbasis konsep Eco design. Penelitian ini menggunakan metode deskriptif kualitatif dan kuantitatif dengan mengambil data persepsi dan preferensi Masyarakat untuk mendapatkan solusi desain. Hasil dari penelitian ini menunjukkan bahwa kualitas desain saat ini kurang baik dengan kerusakan pada fasilitas dan utilitas sehingga menurnkan estetika. Persepsi masyarakat menunjukkan bahwa taman terasa nyaman saat pagi dan sore hari namun tidak didukung denga kelayakan fasilitas dan utilitas. Preferensi masyarakat berupa adanya fasilitas pendukung seperti bench, foodcourt, toilet umum, amphitheater, dan playground serta penggunaaan desain modern yang geometrik dan organik. Konsep ecodesign diimplementasikan sebagai konsep dasar pada proses desain. Konsep desain Taman Amri Yahya mengusung perahu kajang dan sungai yang menggambarkan budaya dan ciri khas identitas Kabupaten OKI., As a city park, Amri Yahya Park has a strategic and potential location but still needs a clear design pattern and functional concept. The problems found are the arrangement of less organized plants, lack of softscape and hardscape maintenance, and unclear landscape design patterns so the visual quality of the landscape decreases. This study aims to identify and analyze design quality and function based on the potential and constraints of Amri Yahya Park, analyze community perceptions and preferences on the condition of Amri Yahya Park as a reference source in the design process, and make suggestions for designing Amri Yahya Park based on the eco-design concept. The method used in this research is a descriptive qualitative and quantitative methods by taking data perceptions and community preferences to obtain design solutions. The results of this study indicate that the current design quality is not good with damage to facilities and utilities thereby reducing aesthetics. Community perceptions indicate that the park feels comfortable in the morning and evening but it is not supported by proper facilities and utilities. Community preferences include supporting facilities such as benches, food courts, public toilets, amphitheater, and playgrounds as well as the use of geometric and organic modern designs. The eco-design concept is implemented as a basic concept in the design process. The design concept for Amri Yahya Park is perahu kajang and river flow which depicts the culture and identity characteristics of OKI Regency.

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.
