Judul: Perilaku Kuau Raja (Argusianus argus argus Linnaeus,1766) di Taman Burung Taman Mini Indonesia Indah
Abstrak: Kuau raja (Argusianus argus argus) adalah spesies burung yang dilindungi karena populasinya yang menurun seiring dengan hilangnya habitat aslinya. Hal itu mendorong upaya pelestarian kuau raja secara eksitu, salah satunya di Taman Burung TMII. Penelitian ini dilatar belakangi oleh minimnya data mengenai perilaku harian kuau raja. Penelitian ini bertujuan untuk mengidentifikasi dan mendeskripsikan perilaku kuau raja serta menganalisis pengaruh kandang kubah terhadap perilaku kuau raja. Penelitian ini dilakukan pada bulan Maret-April 2019 di Taman Burung TMII menggunakan metode focal animal sampling. Hasil penelitian menunjukkan terdapat enam jenis perilaku kuau raja yang teramati yakni perilaku bersuara, bergerak, menelisik, makan, minum, dan istirahat. Frekuensi dan durasi perilaku tertinggi baik oleh jantan maupun betina adalah perilaku istirahat. Aktivitas harian kuau raja berlangsung selama 11 jam mulai pukul 06.00 WIB hingga 18.00 WIB. Hasil penelitian menunjukkan bahwa frekuensi perilaku menelisik dan minum secara signifikan dipengaruhi oleh kandang kubah, sedangkan frekuensi perilaku bersuara, bergerak, istirahat dan makan tidak secara signifikan dipengaruhi oleh kandang kubah. Sementara itu, durasi perilaku makan, bergerak, minum dan istirahat secara signifikan dipengaruhi oleh kandang kubah, sedangkan durasi perilaku menelisik dan bersuara tidak secara signifikan dipengaruhi oleh kandang kubah.

Abstrak: Great Argus (Argusianus argus) is a member of large birds in the Phasianidae that more often use primary forest and its distribution includes Malaysia, Borneo, and Sumatra. The purpose of this research is to study and describe the behaviour of the great Argus and identify patterns of behavior in several types of habitat (primary forests, riparian, and former fire). Behavior was observed by using focal animal sampling and one-zero sampling methods, that are then analyzed using persentage of behavior. The encounter of Great argus only occurred in primary and riparian habitat. Daily behavior obtained consisted of seven behavior, those are: epimeletic behavior (probe) (32,26%), vocal behavior (31.48%), investigative behavior (18.07%), foraging (9,19%), walking (6,82%), resting (1.87%), and sexual behavior (0.31%).

Judul: Membran Komposit Kitosan-Natrium Alginat untuk Aplikasi Direct Methanol Fuel Cell
Abstrak: Composite of chitosan and sodium alginate can be utilized as base material of proton exchange membrane (PEM). The composite membranes were produced by various concentrations of chitosan-sodium alginate, namely 3:3, 3:4, 3:5, 3:6, 4:3, 5:3, and 6:3 (% b/v). The composites were characterized by using Fourier transform infrared spectrophotometer (FTIR), scanning electron microscope (SEM), and were tested for the performance as PEM from the proton conductivity obtained by using impedance spectrometer. The FTIR spectrum indicated the NH3C group at 1637.29 cm-1 and symmetrical COO group at 1253.68 cm-1 indicating interactions between chitosan and sodium alginate. SEM micrographs showed that the composite membrane was nonporous. Composite membrane with 3:5 chitosan-sodium alginate composition had the highest proton conductivity, namely 9.594 × 10-7 S/cm. Based on this research results, chitosan-sodium alginate composite membrane can be applied well in direct methanol fuel cell system.
