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: Sistem Absensi Berbasis RFID Menggunakan Raspberry.
Abstrak: Absensi dalam suatu instansi merupakan salah satu aspek dalam pengelolaan sumber daya manusia. Informasi yang akurat dan terperinci mengenai kehadiran karyawan dapat menentukan prestasi kerja, gaji, produktivitas, atau kemajuan instansi secara umum. Dalam perkembangannya, sistem pencatatan absensi karyawan dapat dikategorikan menjadi dua yaitu secara manual dan otomatis menggunakan mesin. Untuk mendapatkan sistem yang akurat dan praktis diperlukan teknologi modern, salah satunya adalah RFID dan Raspberry Pi. Teknologi RFID merupakan salah satu contoh dari sistem otomatis yang berkaitan dengan identifikasi. Ukuran Raspberry Pi tergolong kecil dan dapat dibeli dengan harga yang terjangkau. Oleh karena itu dengan teknologi RFID dan Raspberry Pi diharapkan dapat membuat sistem absen yang terintegrasi dengan aplikasi web sehingga memudahkan pengelolaan dan penyediaan data serta bekerja secara efisien. Hasil yang didapat dari penelitian ini menunjukkan penggunaan RFID sebagai modul absen dan Rasbperry Pi sebagai server lokal memudahkan rekapitulasi data pada sistem absensi.

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.
