Judul: Ketahanan Benih Udang Vaname Litopenaeus vannamei SPF (Specific Pathogen Free) Terhadap Infeksi Buatan TSV (Taura Syndrome Virus)
Abstrak: White shrimp culture had suffered from losses due to the outbreak of TSV in which mortality could achieved 95%. Therefore SPF shrimp is required as a preventive effort. This research was conducted to evaluate the resistance of white shrimp seed obtained from several SPF broodstock to TSV. Infection of TSV was carried out by feeding flesh of TSV-infected shrimp to PL 30 for 2 days at a feeding rate of 50%. After that, shrimp was fed commercial diet at 10% feeding rate till the end of experiment (11 days of culture). Parameters observed included survival rate, clinical symptoms, and weigth gain. After 11 days of culture, all the tested shrimps were infected, showing clinical symptom namely black spot on the body and the tail became red. The highest survival rate was obtained at S6 code (77,33±3,51%), while the lowest was observed at S4 code but statistically was different significantly (P<0,05) compared to other.

Judul: Survival of Vaname Shrimp Given Recombinant Viral Protein Inhibitor Through Feed With Different Frequency Against WSSV Infection
Abstrak: White spot syndrome virus (WSSV) merupakan patogen yang sangat sering menginfeksi udang. Penelitian ini bertujuan menguji efektivitas rekombinan viral inhibitor protein (VIP) melalui pakan dengan frekuensi berbeda terhadap tingkat kelangsungan hidup udang vaname yang diuji tantang dengan WSSV. Penelitian ini dilakukan pada bulan Agustus-Oktober 2022 di Labroratorium Marikultur, analisis respons imun di Laboratorium Reproduksi dan Genetika Ikan, Departemen Budidaya Perairan, Fakultas Perikanan dan Ilmu Kelautan, Institut Pertanian Bogor. Penelitian ini dilaksanakan secara eksperimental menggunakan rancangan acak lengkap. Penelitian dilakukan menggunakan empat perlakuan dengan lima ulangan untuk uji tantang. Parameter uji yang diukur yakni tingkat kelangsungan hidup (TKH), total haemocyte count (THC), dan aktivitas phenoloxidase (PO). Data diolah menggunakan Microsoft Excel 2010 dan dianalisis dengan analisis ragam (ANOVA). Hasil penelitian ini menunujukkan bahwa pemberian VIP dengan frekuensi setiap hari memberikan hasil terbaik setelah diinfeksikan dengan WSSV yang menghasilkan tingkat kelangsungan hidup mencapai 45,33% dibandingkan (P<0,05) kontrol positif yang memiliki tingkat kelangsungan hidup terendah yakni 9,33%., White spot syndrome virus (WSSV) is a pathogen that often infects shrimp. This study aims to test the effectiveness of recombinant viral inhibitor protein (VIP) by feeding with different frequencies on the survival rate of vannamei shrimp challenged with WSSV. This research was conducted in August-October 2022 at Mariculture Laboratory, immune response analysis at Fish Reproduction and Genetics Laboratory, Department of Aquaculture, Faculty of Fisheries and Marine Sciences, IPB University. This research was carried out experimentally using a completely randomized design. The study was conducted using four treatments with five replications for the challenge test. The test parameters measured were survival rate (TKH), total haemocyte count (THC), and phenoloxidase (PO) activity. Data were processed using Microsoft Excel 2010 and analyzed by analysis of variance (ANOVA). The results of this study showed that giving VIP with a daily frequency gave the best results after being infected with WSSV which resulted in a survival rate of 45.33% compared to (P<0.05) the positive control which had the lowest survival rate of 9.33%.

Judul: Pengaruh Konsep Lanskap Keraton Ngayogyakarta Hadinigrat terhadap Lanskap Kota Yogyakarta
Abstrak: Kota Yogyakarta merupakan kota yang menjadi pusat kebudayaan Jawa dengan adanya Keraton Yogyakarta dan bekas Kerajaan Mataram Islam. Sebagai sebuah kota dengan latar historis kerajaan yang kuat dan legilimasi keraton yang sampai saat ini masih cukup kuat, maka kehidupan keraton mempengaruhi pula kehidupan rakyat Kota Yogyakarta. Keraton dan kawasan kerajaan dibangun berdasarkan konsep-konsep filosofis yang menghasilkan wujud fisik penuh makna dan merupakan cikaI bakaI Kota Yogyakarta. Namun dalam perkembangannya, dengan adanya pengaruh pendatang dan globalisasi, malta banyak terjadi pergeseran nilai dan kebudayaan serta filosofi yang melingkupinya Hal. ini dikhawatirkan akan semakin mengaburkan identitas Kota Yogyakarta.
