Abstrak: Kuau raja merupakan jenis burung yang populasinya semakin terbatas sehingga diperlukan upaya konservasi ex-situ untuk mendukung upaya pelestariannya. Taman Burung TMII merupakan lembaga konservasi ex situ, sekaligus sebagai sarana eduwisata bagi masyarakat. Penelitian ini bertujuan mengidentifikasi aspek pemeliharaan kuau raja, persepsi dan pengetahuan pengunjung, dan nilai WTP pengunjung terhadap upaya pelestarian kuau raja di Taman Burung TMII. Penelitian ini dilaksanakan di Taman Burung TMII Jakarta pada bulan Maret sampai April 2022. Metode yang digunakan adalah observasi lapang, wawancara, survei, dan studi literatur. Hasil penelitian menunjukkan aspek pemeliharaan sudah cukup baik, namun perlu beberapa perbaikan dan penambahan fasilitas perkandangan dan pakan. Pengunjung memiliki persepsi positif dan pengetahuan cukup tinggi tentang kuau raja sebagai spesies burung dilindungi, dan perlunya usaha pelestariannya baik insitu maupun exsitu. Pengunjung bersedia membayar untuk mendukung pelestarian kuau raja dengan nilai rataan WTP sebesar Rp. 36.111 dengan perkiraan nilai ekonomi total sebesar Rp. 188.968.000,00 perbulan. Faktor tingkat pendidikan terakhir dan besarnya pendapatan pengunjung berpengaruh nyata terhadap besar-kecilnya nilai WTP dari pengunjung., Great argus is a species of bird whose population is increasingly limited so ex-situ conservation efforts are needed to support its conservation efforts. TMII Bird Park is an ex situ conservation and as of tourism-based education for public. This study aims to identify aspects of the maintenance of Great argus, the perception and knowledge of visitors, and the value of visitors' WTP for efforts to preserve Great argus in the TMII Bird Park. This research was conducted at TMII Bird Park Jakarta from March to April 2022. The methods used are field observations, interviews, surveys, and literature studies.

Judul: Sintesis Krisin dari Floroglusinol
Abstrak: Flavone is a class of flavonoid, widely distributed in vascular plants. Flavones containing hydroxyl groups at 5 and 7 position are quite important regarding their biological activities and their abiquity in nature. Flavone having hydroxyl groups only at position 5 and 7 or 5,7-dihydroxyflavone is known as chrysin. In this study, crude chrysin had been successfully synthesized in 3 steps from phloroglucinol as starting material. Phloroglucinol was acetylated with acetonitrile and HCl gas, resulting phloroacetophenone amount to 74%. Phloroacetophenone benzoylation with 4.5 equivalents of benzoyl chloride produced tribenzoyl phloroacetophenone in 103–107% of yield and the subsequent Baker-Venkataraman rearrangement of the ester by using KOH in dried pyridine produced crude chrysin, with conversion percentage of 71.62%. All synthetic products had been characterized by melting point and spectroscopically.
