Judul: Pola penggunaan waktu untuk berbagai kegiatan mahasiswa tingkat persiapan bersama pada semester pertama
Abstrak: Tujuan penelitian adalah untuk mengetahui pola penggunaan waktu mahasiswa Tingkat Persiapan Bersama pada semester pertama. Data penelitian merupakan hasil survei terhadap kegiatan yang umumnya dikerjakan secara kronologis selama 24 jan oleh mahasiswa TPB yang bukan pengulang pada tahun 1988. Hasil penelitian diperoleh dari penyebaran angket yang bersifat terbuka kepada responden mahasiswa Tingkat Persiapan Bersama. Prosedur yang digunakan dalam pemilihan mahasiswa untuk terpilih sebagai responden dari populasi mahasiswa TPB digunkan penarikan contoh acak sederhana. Metode analisis yang digunakan adalah metode deskriptif, penyajian penggunaan waktu data penelitian dilakukan dengan memplot antara waktu pelaksanaan kegiatan dengan kegiatan yang dikerjakan oleh responden. Kegiatan-kegiatan yang umumnya dikerjakan oleh mahasiswa TPB adalah bangun pagi hari, mandi pagi, sholat subuh atau saat teduh, membersihkan kamar tidur, sarapan pagi, membaca surat kabar atau majalah, persiapan kuliahkuliah pada hari kuliah (kerja) atau belajar persiapan ujian pada hari libur waktu menjelang ujian akhir, rekreasi pada hari libur, sholat dhuhur, makan siang, mendengarkan radio/tape recorder, tidur siang, mandi sore, sholat ashar, jalan-jalan/santai-santai sesama teman atau ngobrol, sholat magrib, makan malam, sholat isya, belajar malam hari, menonton tv, istirahat, belajar malam, dan mulai tidur malam hari. ...

Judul: Autonomy, self-adjustment, and stress of the first-year students of Bogor Agricultural University academic year 2011/2012
Abstrak: Tujuan dari penelitian ini adalah mengkaji kemandirian, penyesuaian diri, dan stres mahasiswa Tingkat Persiapan Bersama (TPB) Institut Pertanian Bogor (IPB) tahun akademik 2011/2012. Pengumpulan data dilakukan pada bulan Mei 2012 di asrama TPB IPB, Dramaga. Penelitian ini menggunakan desain cross sectional dan retrospektif. Teknik pemilihan contoh menggunakan stratified proporsional random sampling berdasarkan jenis kelamin dengan melibatkan 205 mahasiswa TPB (85 mahasiswa dan 120 mahasiswi). Hasil uji beda menunjukkan bahwa mahasiswa lebih mandiri dibandingkan mahasiswi. Hasil uji regresi menunjukkan bahwa lama pendidikan ibu berpengaruh positif terhadap kemandirian mahasiswa TPB. Kemandirian dan pendapatan ayah berpengaruh positif terhadap penyesuaian diri mahasiswa TPB. Kemandirian, penyesuaian diri, dan umur ibu berpengaruh negatif terhadap stres mahasiswa TPB. Berdasarkan hasil penelitian, orang tua serta support system lainnya seperti konselor sebaiknya memberikan dukungan kepada mahasiswa agar dapat melakukan penyesuaian diri dan menghadapi stres di tingkat pertama., Kemandirian, Penyesuaian Diri, dan Stres Mahasiswa Tingkat Persiapan Bersama (TPB) Institut Pertanian Bogor Tahun Akademik 2011/2012

Judul: Phylogeography and Species Limits in the Papuan White Snake (Micropechis ikaheka) (Reptilia: Serpentes: Elapidae)
Abstrak: Papua white snake, Micropechis ikaheka, has been distingushed into two subspecies M.i. ikaheka and M.i. fasciatus. However, due to lack of data on their morphology, distribution and ecology, both subspecies often ignored in scintific discussions and refers only byas , Micropechis ikaheka. This study was designed to document the differences between M.i. ikaheka and M.i fasciatus by using scales characteristics and reproductive organ or hemipenes. The study also examine, zoogeography, habitat, diet and cannibalism of both subspecies to better understanding the the ecology of one of the most venomous snakes in the world. This study consists of three topics with method and also different in the size samples, respectively. The first study is the histology and microtopography of the skin were studied using paraffin method and Scanning Electron Microscope (SEM). The second is the hemipenis were examined by following Myers and Cadle (2003), and Zaher and Prudente (2003). The third is the abdominal surgery was carried out to document diet type and the investigate phenomenon of cannibalism in the snake. Specimens for this study came from the collection from Museum Zoologicum Bogoriense (MZB) and Universitas Negeri Papua’s Laboratory (LZU). The research result also indicated that the markers of skin and hemipenis described the same structure and microornamentation in all M. ikaheka groups being compared. Based specimens examined morphological descriptions do not s support the further differentiation in Micropechis. In short, two markers that used in this study could not sufficiently indicate the differences in the level of species and subspecies of M. ikaheka. The study, however, were able to delineate zoogeography and skin color patterns, which fall into four groups: M. i. ikaheka; M. i. fasciatus. M. i. ssp. “intermediate”; and M. i. ssp “black”. This study also revealed that color variations did not overlap in their geographic distribution. It is therefore, it suggested that environmental factors may contribute to the skin color variations. It also assumed that habitat discontinuous and biogeography factors may also cause the loss of the connection between the original populations (vicarians) or follow colonization events (dispersal). The examined of 22 stomach contents of M. ikaheka shows this species is carnivorous, and prey on vertebrates such as amphibians, fish, reptiles, and Mammals. These snakes are opportunistic predators since they prey on all that can be captured, but mainly reptiles (61.5%), followed by mammals and fish (both 15.4%), and amphibians (7.7%). Although categorized as terrestrial animal, the diet study showed that M. ikaheka snakes often go into the water to hunt for fish (the sample from Yapen island), including eel (the sample from Aru island). Based on prey items indentified, there is evidence that M. ikaheka is cannibal. At this time, there still no record on reason for cannibalism, but it is assumed that cannibalism was due to competition between populations and means to control population.
