Judul: Kajian Aktivitas Harian Dan Perilaku Reproduksi Komodo (Varanus komodoensis, Ouwens 1912) Di Taman Margasatwa Ragunan
Abstrak: The aims of this study was to explore the daily activities and reproduction biology of 16 komodo dragons (Varanus komodoensis) in ex-situ hábitat at Taman Margasatwa Ragunan (TMR), Jakarta. The methods include observation, interview, and processing secondary data. Daily activities were observed such as basking, sheltering, walking, wallowing, and feeding. Basking and sheltering were displayed as the dominant daily activities which was spent for 27- 41% and 54 - 70% during the observation, respectively. While courtship, mounting, laying eggs were observed as reproductive behaviours during the study. Breeding problem of the komodo dragons in TMR was the failure of eggs incubation in the last five years.

Judul: Perilaku Komodo (Varanus komodoensis) di Taman Margasatwa Ragunan
Abstrak: The komodo (Varanus komodoensis) is the world's largest lizard that prone to extinction since they only scattered in some small islands in eastern Indonesia. One preservation effort of the dragons is by breeding them in captivity places, such as Jakarta Ragunan Zoo. Eventhought in the captivity, it does not mean there are no problems faced by the komodo. The main problems are because of differences in the weather and environmental conditions. Therefore, the aim of the research is to conduct behavioral assessments of the komodo preserved in the Ragunan Zoo as the first step to resolve the problems. We used observational method called scan sampling. Observations were conducted in two periods of time, i.e. during the daylight (06.00 am-06.00 pm) and evening (6.00 pm-06.00 am). Observations of the behavior of the komodo included walking, stay still, sun bathing, rubbing body, yawn, drinking, eating, climbing, secreting saliva, craning of the tongue, and running. During the daylight, some of the behaviors were more dominant, i.e. walking, stay still, sun bathing, climbing, secreting saliva, and craning of the tongue. While during the night stay still was dominant.

Judul: Pembuatan Film Tipis Lithium Niobat (LiNbO3) Menggunakan Metode Chemical Solution Deposition (CSD) dengan Variasi Kecepatan Putar (Rpm).
Abstrak: Film tipis merupakan salah satu aspek yang mendapat perhatian sangat besar dalam bidang material, karena film tipis merupakan material menarik yang memiliki sifat optik yang sangat tergantung pada konstanta dielektrik, indeks bias, dan energi gap. Lithium Niobat (LiNbO3 ) dapat digunakan sebagai pelapis pada film tipis karena memiliki sifat piezoelektrik, electrooptical, pyroelectrical dan photorefractive yang sangat baik. Film tipis Lithium Niobat (LiNbO3 ) ditumbuhkan menggunakan metode Chemical Solution Deposition (CSD) dengan variasi kecepatan 3500 rpm, 5000 rpm, 6500 rpm, dan 8000 rpm. Metode ini memiliki keunggulan dapat mengontrol stokiometri film tipis dengan kualitas yang baik, prosedur yang mudah dan membutukan biaya yang relatif murah. Energi band gap yang dihasilkan dari film tipis Lithium Niobat (LiNbO3) berkisar antara rentang 2.1 eV – 2.8 eV dengan indeks bias berada pada rentang 2.18-3.2. Film tipis LiNbO3 memiliki parameter kisi a=b=5.54Ǻ dan c = 16.35 Ǻ. Struktur morfologi film tipis adalah permukaan yang homogen dan ukuran kristal berada pada rentang 0.417 μm – 0.680 μm.
