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 dan Desain Jembatan Frame, Kolom “V”, Box Girder, dengan Mempertimbangkan Beban Gempa
Abstrak: The growing of economic, social, cultural and environmental influenced by the availability of infrastructure, such as bridges. The bridges often used as a city icon. Selection of bridge structures important to adapt the structural strength and stability, serviceability structure, durability, ease of implementation, economic, and aesthetic. Strength of bridge structure in Indonesia is strongly influenced by earthquake load. Therefore, the construction of flyover Simpang Jam Batam needs to be built and studied. This study aims to analyze and design the frame bridge with "V"column and boxgirder, consider to earthquake load, and design reinforced concrete structures. The methods are data collection, preliminary dimension, modeling in CSI Bridge, and reinforcement design. The study started at April to July 2013 in Department of Civil and Environmental Engineering, Bogor Agricultural University. The result is the maximum forces obtained occurs in combination ULS-4a and SLS-4a, that moment values are 66298.6 kNm and 37494 kNm, whereas shear force values are 9735.71 kN and 6346.73 kN. Based on the results, boxgirder flexural reinforcement at top slab is D19-100 and D19-200, bottom slab and web are D16-150. Meanwhile, boxgirder shear reinforcement needs only at web is D16-150. Column "V" reinforcement is D25-150 to flexural and D16-150 to shear.

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.
