Judul: Analisis Kinerja Struktur Atas Tol Bogor Outer Ring Road Seksi 2-B Terhadap Beban Gempa.
Abstrak: Gempa bumi berpotensi menyebabkan kerusakan material berupa kerusakan pada bangunan dan fasilitas umum. Penelitian ini bertujuan untuk menganalisis kinerja struktur tol BORR Seksi 2B terhadap beban gempa. Analisis dilakukan dengan permodelan yang dirancang dari P30-P34 berdasarkan data yang diperoleh dari PT Marga Sarana Jabar dengan menggunakan CSI bridge v20 dan mengacu pada peraturan-peraturan serta peta zonasi Gempa Indonesia. Penelitian dilakukan dari bulan Mei - Agustus 2018. Hasil penelitian menunjukkan bahwa terdapat 12 mode getar yang mungkin terjadi pada struktur jembatan. Periode terbesar terjadi pada mode 1 yaitu sebesar 0,66122 det yang sudah mewakili prilaku struktur sehingga nilai kekakuannya sebesar 1026,146 kN/m. Displacement terbesar yang terjadi pada jembatan sebesar 18,8 mm. Gaya-gaya dalam nominal jembatan aman terhadap beban ultimit yang telah dimasukkan faktor gempa dengan nilai ϕMn 69276,7 kNm ≥ Mu = 72894,6397 kNm, ϕVn = 11868,22 kN ≥ Vu = 11868,2 kN, dan ϕTc / ϕTn = 78453,60 kNm ≥ Tu = 68297,1 kNm. Dari perhitungan tulangan yang dilakukan nilai tulangan lentur, geser , dan puntir balok dapat dikatakan aman.

Judul: Analisis Struktur Jalan Layang Tol Bogor Outer Ring Road (BORR) Seksi IIA (P6-P12) terhadap Gempa
Abstrak: Flyovers is one relevant solution to overcome traffic jam is often the case in big cities. flyovers BORR section IIA (Kedunghalang-Kedungbadak) P6-P12 span is the object of research the analysis of structures against earthquake loads are analyzed by modeling the CSI Bridge v.15 with secondary data obtained from the prime contractor and refer to such regulations RSNI T-02-2005, RSNI T-12-2004, SNI 03-1725-1989, SNI 2833-2008, RSNI 03-1726-2010 dan Peta Zonasi Gempa Indonesia 2010. This research was conducted in March-May 2014 in the Department of Civil and Environmental Engineering, Bogor Agricultural University and aims to analyze the bridge structure against earthquakes. Based on the result of this research, is obtained that bridge structure are safed under earthquake loads that is ϕMn = 23003.18 kNm ≥ Mu = 19768.5094 kNm, ϕVn = 4418.796 kN ≥ Vu = 4418.796 kN and ϕTc = 60851.21 kNm ≥ 𝑇��������𝑢�������� = 46688. 56 kNm. The value of flexural, shear and torsional reinforcement beam and pier reinforcement in existing is safed under earthquake loads based on Peta Gempa Indonesia 2010.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
