Judul: Analisis Kinerja Waktu dan Penerapan Building Information Modeling (BIM) pada Proyek Pembangunan Transmart Bogor.
Abstrak: Kinerja manajemen proyek yang terintegrasi dengan model tiga dimensi (3D) dapat mengoptimumkan analisis kinerja pelaksanaan. Seiring dengan perkembangan teknologi informasi, pemodelan tiga dimensi (3D) dapat dilakukan dengan menggunakan program Tekla Structures. Tujuan penelitian ini adalah mengaplikasikan building information modeling (BIM) sampai pemodelan empat dimensi (4D), menganalisis kinerja waktu, dan menentukan faktor penyebab jika terjadi keterlambatan serta tindakan untuk menanggulanginya. Pemodelan 3D meliputi pemodelan pondasi, kolom, balok, pelat, tangga, dan atap. Pemodelan 4D dilakukan dengan penambahan jadwal pekerjaan pada pemodelan 3D yang telah dibuat. Analisis kinerja waktu dilakukan dengan metode kurva S. Penerapan BIM telah dilakukan hingga diperoleh pemodelan 3D dan 4D. Berdasarkan nilai deviasi, proyek ini mengalami keterlambatan dengan nilai deviasi tertinggi pada bulan Februari sebesar -11,905%. Keterlambatan tersebut dikarenakan faktor cuaca dan keterlambatan supplier. Percepatan pekerjaan dilakukan dengan menambah jam kerja (lembur) serta penambahan jumlah pekerja.

Judul: Analisis Kinerja Waktu dan Aplikasi Building Information Modeling (BIM) pada Proyek Pembangunan Pengembangan RSUD Wates
Abstrak: Pengendalian proyek perlu dilakukan untuk mengetahui kemajuan pembangunan pada suatu proyek. Penerapan BIM 4D dapat mempermudah dan mengoptimumkan analisis kinerja pelaksanaan melalui visualisasi kemajuan pekerjaan. Tujuan penelitian ini adalah mengaplikasikan building information modeling (BIM) sampai pemodelan empat dimensi (4D), menganalisis kinerja waktu, dan menentukan faktor penyebab jika terjadi keterlambatan serta tindakan perbaikannya. Pemodelan 3D meliputi pemodelan kolom, pondasi, balok, pelat, tangga, ramp dan atap. Pemodelan 4D dilakukan dengan menautkan jadwal pekerjaan pada pemodelan 3D yang telah dibuat. Hasil pemodelan 4D berupa visualisasi kemajuan pekerjaan. Analisis kinerja waktu dilakukan dengan metode kurva S. Berdasarkan hasil analisis, proyek ini mengalami keterlambatan pada bulan September 2018 dan Oktober 2018 yang mencapai nilai deviasi sebesar -3,5996%. Keterlambatan tersebut dikarenakan terhambatnya proses supply material tiang pancang dan keadaan cuaca. Percepatan pekerjaan dilakukan dengan menambah jam kerja (lembur) sehingga nilai deviasi menjadi positif pada bulan November 2018 sampai Januari 2019.

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.
