Judul: Analisis persepsi karyawan operasional terhadap pelaksanaan Gardu Tol Otomatis (GTO) dan faktor-faktor produktivitas kerja pada PT Jasa Marga (Persero) Tbk Cabang Purbaleunyi
Abstrak: Kebutuhan masyarakat akan jaringan jalan semakin terdesak seiring dengan peningkatan produksi kendaraan yang tidak sebanding dengan kapasitas jalan yang ada. Terjadinya ketidakseimbangan tersebut salah satunya akibat pertumbuhan volume kendaraan roda empat yang naik sebesar 9% per tahun, sedangkan penambahan panjang jalan dilakukan hanya sebesar 0.01% per tahun, kondisi ini menjadi pemicu terjadinya masalah kemacetan lalu lintas. Konsep tol menjadi sebuah jawaban terhadap tingginya kebutuhan pengembangan jaringan jalan meskipun dalam kondisi anggaran pemerintah yang terbatas. PT Jasa Marga (Persero) Tbk merupakan satu-satunya Badan Usaha Milik Negara (BUMN) yang berperan sebagai pengembang sekaligus operator jalan tol di Indonesia yang memiliki sembilan Cabang, salah satunya adalah Cabang Purbaleunyi. Karakteristik Cabang Purbaleunyi adalah masalah antrian pajang pada gerbang tol. Untuk mengatasi masalah antrian tersebut maka dibuat Gardu Toll Otomatis (GTO), yang merupakan ide kreatif dari Gugus Kendali Mutu Pasteur. GKM Pasteur merupakan salah satu kelompok unit kerja yang ada di Cabang Purbaleunyi pada Gerbang Tol Pasteur. Perusahaan menganggap GTO dapat memberikan dampak positif bagi karyawan operasional.

Judul: Analisis Risiko Operasional Jalan Tol Jagorawi PT Jasa Marga (Persero) Tbk
Abstrak: A large number of vehicles in big cities led to traffic density, until people start switching to use the toll road. Jagorawi is one of the densest toll road, where high flows of traffic cause various risks which related to the operation of toll road. The purpose of this research is to determine the operational risk of Jagorawi toll road and determine the alternative strategies for the smooth operation of toll road. Method of sampling used is non probability sampling with purposive sampling technique. Data analyzed by using cause and effect analysis, Failure Mode Effect Analysis, and Analytical Hierarchy Process. The result indicates that the main risk which has been priority is traffic risk and the highest risk variabel of 21 risk variabels is the delay of infrastructure handling. The right alternative strategy to handle the mentioned risk is by educate the toll road users and inhabitants, develop the instrastructure, invest in quality of human resource, auto gate, and improve the service and safety.

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.
