Judul: Pengaruh bentuk penyajian dan simpulan pesan tentang efek rumah kaca melalui booklet pada peningkatan pemahaman mahasiswa IISIP Jakarta
Abstrak: Penelitian bertujuan untuk mengetahui perbedaan pengaruh: (1) bentuk penyajian pesan satu sisi dan dua sisi, (2) simpulan tersirat dan tersurat. (3) kombinasi yang paling efektif antara bentuk penyajian pesan dan simpulan pesan. Unit eksperimen mahasiswa IISIP peserta MPK. Diambil secara acak: 80 orang (48 wanita dan 32 pria). Lalu dirandom menjadi empat kelompok (12 wanita dan 8 pria). Dirancang untuk eksperimen murni dengan disain faktorial 2 X 2. Peubah bebas adalah bentuk penyajian pesan dua taraf (satu sisi dan dua sisi), dan simpulan pesan tersirat dan tersurat). Peubah terikat adalah peningkatan pemahaman. Instrumen yang digunakan ialah kuesioner dengan koefisien reliabilitas sebesar 0,94. Data identitas responden dianalisis dengan frekuensi dan rataan. Perbedaan pemahaman dianalisis dengan uji pangkat Wilxocon. Untuk membandingkan hasil peningkatan pemahaman digunakan uji Kruskal-Wallis. Sedangkan untuk mengetahui perbedaan hasil perlakuan digunakan uji Wilcoxon-mann-whitney. Hasil penelitian menunjukkan semua perlakuan yang diberikan pada kelompok perlakuan meningkatkan pemahaman responden. Perlakuan penyajian pesan satu sisi dan dua sisi, serta perlakuan pesan tersirat dan tersurat terhadap kelompok perlakuan tidak menunjukkan adanya perbedaan. Peningkatan pemahaman kelompok yang diberi kombinasi perlakuan penyajian pesan dua sisi dan simpulan tersurat berbeda nyata dengan perlakuan penyajian pesan satu sisi dan simpulan tersirat. Begitu juga dengan kelompok yang diberi perlakuan penyajian pesan satu sisi dan simpulan tersurat atau penyajian pesan dua sisi dan simpulan tersirat.

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.
