Judul: Evaluasi Kinerja Waktu Dan Pemodelan 3d Menggunakan Tekla Structures 17 Pada Pembangunan Salak Boutique Tower Hotel, Bogor
Abstrak: Pekerjaan Konstruksi Merupakan Seluruh Kegiatan Pelaksanaan Pembangunan Suatu Bangunan. Seiring Dengan Perkembangan Teknologi Informasi, Telah Banyak Pemodelan Tiga Dimensi (3d) Yang Dikembangkan. Salah Satu Pemodelan 3d Adalah Program Tekla Structures 17. Penelitian Ini Dilaksanakan Pada Bulan Juli-September 2015. Penelitian Ini Dilakukan Untuk Menampilkan Bentuk Dari Komponen Struktur Dengan Pemodelan 3d Serta Menganalisis Kurva S Dan Faktor-Faktor Penyebab Keterlambatan. Jadwal Pekerjaan Pembangunan Yang Dianalisis Adalah Rencana Jadwal Dan Jadwal Realisasi Kegiatan Pembangunan. Kinerja Merujuk Kepada Tingkat Keberhasilan Dalam Melaksanakan Tugas Serta Kemampuan Untuk Mencapai Tujuan Yang Telah Ditetapkan. Hasil Analisis Pada Kurva S Menunjukkan Adanya Deviasi Yang Positif, Namun Ada Pula Beberapa Yang Menunjukkan Nilai Negatif. Adapun Keterlambatan Pada Proyek Pembangunan Ini Disebabkan Oleh Cuaca Yang Tidak Menentu Dan Kurangnya Tenaga Kerja.

Judul: Time Schedule Analysis and Building Information Modeling Application on Jasmine Park Apartment Bogor
Abstrak: Meningkatnya pembangunan dibutuhkan pekerjaan dengan tingkat produktivitas tinggi, efektif, dan efisien. Tujuan penelitian yaitu penerapan Building Information Modeling sampai pemodelan empat dimensi (4D) dengan menggunakan software Tekla Structure, menganalisis kinerja waktu dari perbandingan bobot pekerjaan rencana dan bobot pekerjaan realisasi, dan menentukan faktor penyebab jika terjadi keterlambatan serta solusinya. Penelitian dilaksanakan pada bulan April-Juni 2020, di proyek pembangunan Jasmine Park Apartment. Alat dan bahan yang digunakan adalah laptop yang dilengkapi dengan software AutoCAD, Tekla Structures ® 2019i, Microsoft Office 2016, data primer dan data sekunder. Pemodelan 4D dilakukan dengan penambahan jadwal pekerjaan pada pemodelan 3D yang telah dibuat dengan tools task manager. Berdasarkan hasil analisis dengan kurva S nilai deviasi negatif tertinggi pada bulan Juni 2020 sebesar -13,67%. Keterlambatan utama pada proyek ini adalah pengadaan logistik mekanikal, elektrikal, dan plumbing dan keadaan cuaca. Percepatan pekerjaan dilakukan dengan menambah jam kerja serta penambahan jumlah pekerja.

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.
