Judul: Rancang Bangung Sistem Otomasi Presentasi Kuliah Berbasis Radio Frequency Identification (RFID)
Abstrak: Technology has facilitated human activity in many fields. Nowadays, learning process is using computer and LCD projector to display the lecture presentations. However, it comes with the need for time efficiency. It takes a little time to search and open the lecture presentation thereby reducing the time of learning activities. Radio frequency identification (RFID) is a technology that has been developed in many bussiness field, such as health, sport, security, entertainment, and many more. In this research, RFID is used to support education sector. The aim is to develop an application that can display lecture presentation when the lecturer who bring the RFID tag with him through the door that has RFID censor. The RFID censor simply reads the tag and search the class schedule to ensure that the lecturer has a correct schedule and then it displays the class presentation when the query provide the positive result. The experiments show that the system searching and opens the class presentation in about 2 seconds. The application provides the solution that needed for time efficiency in learning process.

Judul: Rancang Bangun Sistem Otomasi Presentasi Kuliah Menggunakan Raspberry Pi dan Radio Frequency Identification (RFID)
Abstrak: Kegiatan mempersiapkan slide presentasi oleh dosen pada setiap awal pertemuan kuliah akan mengurangi efektifitas waktu belajar. Penelitian sebelumnya memiliki kekurangan dalam penerapannya karena membutuhkan biaya yang besar untuk penyediaan komputer di setiap kelas dan peletakan berkas yang bersifat lokal. Salah satu solusi untuk mengatasinya adalah dengan mengganti komputer desktop biasa dengan single board computer (SBC), Raspberry Pi. Penelitian ini bertujuan untuk merancang dan membangun sistem otomasi presentasi kuliah dengan radio frequency identification (RFID) sebagai pembawa id untuk diteruskan ke Raspberry Pi yang akan mengirimkan query sesuai dengan id yang dibaca ke server database. Apabila id terdaftar dan sesuai jadwal yang ada, Raspberry Pi akan mengirimkan query ke server FTP untuk mengunduh slide presentasi yang relevan. Selanjutnya, Raspberry Pi akan menampilkannya melalui proyektor. Seluruh sistem bekerja dengan baik dalam empat skenario pengujian, yaitu: pengujian pembacaan tag, pengujian posisi tag, pengujian akurasi, dan pengujian waktu. Hasil pengujian waktu menunjukkan bahwa sistem dapat menampilkan slide kuliah dalam waktu rata-rata 60.145 detik. Hal ini dapat menghemat waktu kegiatan perkuliahan sehingga berjalan lebih efektif.

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.
