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.

Judul: Sebaran dan Pola Perilaku Kuau raja (Argusianus argus) di Stasiun Penelitian Way Canguk, Taman Nasional Bukit Barisan Selatan (TNBBS)
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-Zeolit untuk Aplikasi Direct Methanol Fuel Cell
Abstrak: Direct methanol fuel cell (DMFC) is a fuel cell that utilize methanol as the fuel source. The electrolyte membrane used in the DMFC system in this research was chitosan-zeolite composite membrane. The composite membrane was synthesized with chitosan-zeolite composition variation of 1:1, 1:2, 1:3, and 2:1. The membranes were analyzed by Fourier transform infrared spectrophotometer (FTIR) and scanning electron microscope, and for the specific gravity. Membrane performances were tested with methanol uptake, methanol permeability, conductivity, and potential difference in the DMFC system. The FTIR spectrum showed no formation of new functional groups inducating that the composite membrane was a result of physical mixing. Morphological analysis showed that the membrane was nonporous. Chitosan-zeolite 1:3 composite membrane had the highest specific gravity and methanol uptake, 1.4226 g/mL and 41.44%, respectively. The highest proton conductivity was showed by the 1:2 chitosanzeolite composite membrane, namely 7.2946× 10-7 S/cm. Based on this research results, chitosan-zeolite composite membrane can be applied in DMFC system.
