Judul: Analisis Struktur Bangunan Apartemen Grand Emerald, Kelapa Gading, Jakarta Utara menggunakan Peta Gempa 2002 dengan Analisis Statik Equivalent
Abstrak: Perhitungan struktur merupakan langkah penting pada proses awal perencanaan suatu bangunan. Salah satu alat yang dipergunakan untuk menganalisis struktur secara cepat dan tepat adalah ETABS v 9.0.7 yang termasuk dalam Spesific Professional Program Analysis. Dalam perencanaan bangunan bertingkat, banyak langkah yang diperlukan seperti menentukan spesifikasi bahan dan penampang, permodelan struktur tiga dimensi, memberikan input beban hidup, beban super dead load, beban gempa, beban angin, beban kombinasi 1 hingga beban kombinasi 16, dan melakukan tahap penjepitan, serta menganalisis untuk mengetahui gaya-gaya dalam ultimit dari masing-masing elemen struktur pelat, balok, dan kolom. Pada penelitian ini bertujuan untuk membandingkan gaya-gaya dalam ultimit dengan gaya-gaya dalam rencana dan untuk mengetahui apakah dimensi penampang terpasang mampu menahan gaya-gaya dalam ultimit akibat efek pembebanan dari luar. Alat dan bahan yang digunakan dalam penelitian ini yaitu program ETABS v 9.0.7, dan gambar struktur proyek Apartemen Grand Emerald. Analisis pembebanan mengacu pada PBI 1983, dan analisa gempa menggunakan metode analisis statik equivalen.

Judul: Analisis dan Evaluasi Struktur Atas Tower C Grand Center Point Apartement Terhadap Beban Gempa Berdasarkan Peta Gempa Indonesia 2010
Abstrak: Indonesia is a very vulnerable country against earthquakes because of it is located between three active earth slabs like Pacific, Indo-Australian, and Eurasia. The number of volcanoes also make Indonesia become vulnerable too. The occurrence of strong earthquakes produce an energy that can shake everything on the Earth's surface, include tower building. The purpose of this research is to analyze and evaluate the resistance of Tower C Grand Center Point Apartment structure against earthquake load based on Indonesian Earthquake Hazard Map 2010 using static equivalent, respon spectrum and time history method. This research was done in March-June 2013 used secondary data like Shop drawing of Grand Center Point Apartment, then analyzed by ETABS 9.7.2, and Microsoft Excell. Steps in doing this research is collecting data, modeling, structure loading, structure analysis, and structure evaluation. The result of the analysis: the number of the structure reinforcement without earthquake load is larger than the number of the analyze reinforcement, so in this situation the structure is safe. On static earthquake condition with static equivalent analysis, some component still have so many unsafe structure because the existing reinforcement is smaller than the analyze reinforcement. On the dynamic condition, especially with respon spectrum analysis, the structure more weak to against earthquake load rather than on the static condition. This is caused by the structure component with its existing reinforcement which smaller than the analyze reinforcement is increase

Judul: Isolasi dan pemurnian bahan aktif dari mikroalga BTM 11 sebagai inhibitor RNA helikase virus hepatitis C
Abstrak: Hepatitis C virus is the cause of hepatitis C disease which has high virulence. Recent therapy using combination of ribavirin and alpha interferon has short efficiency < 80%. Thus, the discovery of new drug is needed. Antiviral drugs can be discovered through molecular target therapy by finding the inhibitor of RNA helicase that play role in viral replication. Inhibitor can be derived from chemical compound produced by microalgae. The aim of this research was to isolate the active compound from microalgae BTM 11 which had inhibitory activity against RNA helicase. Inhibitory activity was measured by releasing of phospate inorganic in colorimetric ATPase assay. Crude extract was fractionated using gel filtration chromatography with methanol in chloroform solvent. The result showed that Fraction 3 has the highest inhibitory activity which (81.205%). Phytochemical test of crude extract indicated positive flavonoids and coumarin. Thin layer chromatography (TLC) analysis with eluent chloroform: methanol gave 2 spots with Rf value of 0.8 and 0.37. Moreover, high performance liquid chromatography (HPLC) analysis showed absorption peak with the highest abundance at the retention time of 12.483 minute and 16.617 minute was 266 nm and 230 nm. According to these of phytochemical, TLC, and HPLC, inhibitor compound from BTM 11 belongs to flavonoids.
