Judul: Impact of Tag Attachment on Javanese Tree Frog to Its Movement
Abstrak: Metode untuk mengumpulkan data pergerakan amfibi dilakukan dengan cara menambahkan beban pada tubuh amfibi, mungkin menyebabkan gangguan terhadap individu yang diteliti dan mungkin juga mengakibatkan bias terhadap hasil penelitian. Penelitian ini bertujuan untuk menjelaskan dampak pemberian beban sebesar 5% dari bobot tubuh terhadap frekuensi bergerak dan pergerakan vertikal R. margaritifer yang dilakukan di dalam rumah katak di Taman Nasional Gunung Gede Pangrango. Penentuan waktu aktif bergerak diperoleh dengan cara mengamati aktivitas bergerak katak setiap 1 jam selama 1 x 24 jam. Pengambilan data frekuensi pergerakan diperoleh dengan cara mengamati pergerakan 16 individu katak (6 jantan tanpa beban, 6 jantan dengan beban, 2 betina tanpa beban dan 2 betina dengan beban) menggunakan metode Partial-interval sampling dengan panjang interval pengamatan selama 1 menit tanpa ada jeda waktu antar interval. Pengamatan dilakukan pada pukul 17.30 – 18.30, 19.00 – 20.00, 20.30 – 21.30 dan 22.00 – 23.00 WIB menggunakan kategori gerak melompat, berjalan, bergerak tidak berpindah dan diam. Data pergerakan vertikal diperoleh dengan cara mengukur posisi ketinggian katak terhadap tanah setiap 30 menit. Data hasil pengamatan dianalisis menggunakan uji Kruskal-Wallis dan Pearson chi-square.

Judul: Penggunaan metode spool track dalam menelaah pola pergerakan harian katak bertanduk (Megophrys montana) di Taman Nasional Gunung Gede Pangrango, Jawa Barat
Abstrak: Studies on amphibian movement have been reported abroad, including selection of appropriate method. However, there is only two study on amphibian movement reported in Indonesia by Sholihat (2007) and Muliya (2010). This study aims to 1) find suitable material for spool track that well suited with body weight of M. montana., 2) map daily movement patterns of M. montana and describe microhabitat use of M. montana in Gede Pangrango National Park. Research was conducted at Ciwalen and Cibereum. Four types of spool were tried to selected frogs and movements were observed every three hours for 72 hours. Data from observations were then analyzed descriptively and quantitatively. Seven frogs (3 males, 4 females) were observed for 72 hours, each using a spool weight under less than 10% of body mass and there are one male frog were successfully observed using a spool weight more 10% from their body mass. Results showed that suitable spool equipment materials differ for males and females according to their body mass. The best materials for the male frog are made by plastic straws and mica, while for female frog it is made from plastic and piece of carambol powder plastic. Kruskal Wallis test on eight frogs indicated that the movement of every 3 hours during the day are significantly differ between male frogs and female frogs (H = 0.296, df = 1, P> 0.05). While the movement of every 3 hours during the night were significantly differ between male frogs and female frogs (H = 0.000, df = 1, P <0.05). Kruskal Wallis test also shows the average male frog movement every 3 hours in the day and night were not significantly different (H = 0.000, df = 1, P <0.05) in which males did not move much. In the contrary, there is significant differences between day and night 3 hourly movement for female (H = 0.049. df = 1, p <0.05). Females tend to move more during the night compared to afternoon. From observation, it appears that most of the male and female frogs have similar activities during the day, which is sleeping in a protected area away from the sun, such as under leaf litter, rocks, and logs or burrowing in the wood in tree root holes. The purpose of burrowing aims to avoid drought and retain moisture. Observations on microhabitats use showed that most frogs used wet leaf litter during the day and night. Therefore plants as producer of leaf litter needs to be protected.

Judul: Development of IPB Linux Open Source Distribution for Business (ILOSbiz)
Abstrak: The objective of this research is to develop a Linux distribution, ILOSbiz, targeted for office use. This distribution is built through remastering another established distribution, similar to the previously developed ILOS in 2008. In order to know the needed applications to include in ILOSbiz, a survey was conducted involving 15 IPB staffs. We experimented with OpenSUSE and PCLinuxOS using KIWI Image System and My LiveCD to remaster, respectively. PCLinuxOS with My LiveCD was chosen for the final ILOSbiz as it gave better flexibility in the remastering. Comparison with ILOS shows that ILOSbiz has better hardware support.
