Judul: Analisis Kekuatan Struktur Steel Box Girder Jalan Bebas Hambatan Tanjung Priok Seksi E-2A Terhadap Gempa
Abstrak: Tanjung Priok, Jakarta is one of the centers of economic activity in Indonesia, it is supported by the Jakarta International Container Terminal (JITC) and several large plants around it like PT. Pertamina and PT. Bogasari. Ground transportation is a type of transportation that is widely used by businesses to distribute the products it sells, or stored in the warehouse or to be exported out of the country by sea. Economic development of Tanjung Priok so rapidly causing traffic volume in Tanjung Priok is inadequate so the congestion. Congestion happens memperhambat economic activity in Tanjung Priok. Roads and bridges is one of the major factors in the field of transport infrastructure proponent, so do road and bridge infrastructure to keep pace with the development of economic activities in Tanjung Priok. This study aims to determine the structural strength of steel box with modeling grider CSI Bridge. Based on a study of the steel box girder Highway Tanjung Priok safe due to a combination of forces and especially the earthquake.

Judul: Analisis Struktur P106-P107 (Sta.7+388.50 ~ Sta.7+424.25) Jalan Bebas Hambatan Tanjung Priok Seksi E2-A terhadap Beban Gempa
Abstrak: The resistance of building structure, included high way should be considered because Indonesia laid in a highly active tectonic zone. The purpose of this research is to analyze the structure of fly over P106-P107 (Sta. 7 +388.50 ~ Sta. 7 +424.25) at Tanjung Priok Access Road section E2-A under earthquake loads based on Peta Hazard Gempa Indonesia 2010, using response spectrum method. Based on the result of this research, is obtained that for slab, girder, pier head, and pier structure are safed under earthquake loads. The amount of tendon needs for the girder is 125 tendons ( 98.7 mm2) and for the pier head is 558 tendons ( 138.7 mm2). For slab, is used flexural reinforcement D19-150. The shear reinforcement for girder is used D22-132.5 at pedestal area and D13-150 at field area. For pier head is used flexural reinforcement D32 and shear reinforcement D16. The result analysis of pier using software PCA Col showed that the pier capacity is strong enough to endure loading combinations, so the pier structure is safed under earthquake loads

Judul: Hubungan Filogenetik Micryletta inornata (Boulenger, 1890) Berdasarkan Gen 16S rRNA
Abstrak: Tiga spesies dari famili Microhylidae yang berasal dari genus Micryletta sejauh ini diakui: M. inornata, M. steinegeri and M. erythropoda. M. inornata merupakan tipe dari genus ini dan memiliki distribusi yang luas dari Cina selatan, Indochina ke Sundaland (Semenanjung Melayu dan Sumatera). Micryletta inornata pertama kali ditemukan di Sumatera oleh Boulenger pada tahun 1890. Semenjak dideskripsikan pertama kali, belum ada informasi tentang spesies ini di Sumatera. Saya menghitung morfologi beberapa spesimen yang berasal dari Sumatera dengan deskripsi asli dari M. inornata. Penelitian ini menggambarkan spesies berdasarkan spesimen voucher dan mengevaluasi status taksonomi menggunakan data molekuler dari gen 16S rRNA. Kami memperkirakan hubungan filogenetik menggunakan metode Bayesian (BI), Maximum Likelihood (ML), Neighbour Joining (NJ) dan Unweighted Pair Group Method with Arithmetic Mean (UPGMA). Hasilnya menunjukan bahwa genus Micryletta monofiletik terhadap genus lain (Microhyla, Phrynella, Kalophrynus) dalam famili Microhylidae. Monofiletik grup terbagi menjadi 2 kelompok. Kelompok A terdiri dari 5 subkelompok, diwakili oleh populasi M. inornata dari Thailand, Laos, Vietnam, Myanmar and Micryletta steinegeri from Taiwan. Kelompok B terdiri atas populasi Micryletta inornata dari Medan and Aceh (Sumatera), menggambarkan topotipe dari spesies ini. Penelitian ini memastikan bahwa secara morfologi spesies ini teridentifikasi sebagai M. inornata dan terdiri dari beberapa taksa yang berbeda yang perlu diperjelas statusnya di masa yang akan datang.
