Abstrak: Ecology and behavior of whale sharks are rarely known. Since 2011, whale sharks in Teluk Cenderawasih National Park (TCNP) have been a growing popular attraction for tourists because of the sharks' regular association with lift net fisheries (i.e., bagans). The research was aimed to identify sex and body size of each whale shark individual and their surface behavior in Cendrawasih Bay. The observation survey was conducted at bagan fishermen from April to July 2013 to document date, time, location, and number of whale sharks seen each day. A total of 36 males and 1 female were recorded during study period. The size was ranged between 3 to 6 meters, indicating that they were in immature age range. The highest emergence activity of whale sharks was found in the Sowa (76 times), followed by Kwatisore (51 times) and Yaur (7 times). It was indicated that the surface presence of whale sharks near bagans as part of their feeding behavior. This is indicated by the appearance of a whale shark was related to the number of catches of fishermen. Therefore, a better management of bagan fishing operations and tourist attractions are urgent to be implementing for ensuring the vitality of whale sharks in Cenderawasih Bay National Park.

Abstrak: Hiu paus merupakan salah satu jenis ikan terbesar di dunia yang dilindungi secara hukum. Kegiatan wisata hiu paus yang dilakukan di Teluk Saleh menimbulkan dampak negatif bagi kesejahteraan hiu paus. Penelitian ini bertujuan untuk menganalisis kemunculan hiu paus (Rhincodon typus) di Teluk Saleh serta mengevaluasi prosedur operasional baku yang sudah beroperasi di Teluk Saleh Kabupaten Sumbawa, Nusa Tenggara Barat. Penelitian ini dilakukan dengan melakukan observasi langsung dan wawancara. Data yang didapatkan berupa ID hiu paus, tingkah laku, kegiatan wisatawan, dan persepsi wisatawan dan nelayan. Data yang dikumpulkan menunjukkan bahwa kemunculan hiu paus di Teluk Saleh oleh keberadaan bagan dan ketersediaan pakan. Kemunculan hiu paus di Teluk Saleh terjadi saat pagi dan malam hari, namun didominasi pada pagi hari. Banyaknya pelanggaran yang masih dilakukan oleh wisatawan dan operator wisata memerlukan pemantauan lebih lanjut mengenai menilai prosedur operasional baku di Teluk Saleh, Nusa Tenggara Barat., Whale sharks is one of the largest fish species in the world and legally protected. Whale shark tourism activities carried out in Saleh Bay have a negative impact on the welfare of whale sharks.

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.
