Judul: Analisis dan Evaluasi Struktur Atas Gedung Pusat Informasi Kehutanan IPB Terhadap Ketahanan Gempa Berdasarkan Peta Gempa 2010
Abstrak: Indonesia is a very vulnerable country against earthquakes because of it’s located between three active earth slabs like Pacific, Indo-Australian, and Eurasia and also a number of volcanoes. The occurrence of a strong earthquakes will produce an energy that shake everything on the earth's surface, including building structures. The purpose of this research is to analyze and evaluate the resistance of Foresty Information Center Building structure against earthquake based on Indonesian Earthquake Hazard Map 2010 using a static equivalent method. This research was done in March-June 2014 used secondary data like shop drawing of Foresty Information Center Building, then analyzed by ETABS 9.7.2, and Microsoft Excell. The result of the analysis are: there are some componens which still unsafe due to the reinforcement is smaller than analysis result such as longitudinal reinforcement for beam-type B2 (existing 3D 19 < static analysis 5D 19), B3 (existing 6D 19 < static analysis 8D 19), and B3A (existing 4D 19 < static analysis 5D 19), and torsion reinforcement for beam B1, B1A, B2, B2A (existing (without reinforcement) < analisis statik 2D 19), B3 and B3A (existing 2D 19 < static analysis 4D 19), and columns K1-1(existing 12D 19 < static analysis 16D 19), K1-2 (existing 10D 19 < static analysis 13D 19), K3-1 (existing 6D 19 < static analysis 10D 19).

Judul: Analisis Struktur Atas Gedung Student Center Ipb Terhadap Beban Gempa Dengan Metode Statik Ekuivalen Berdasarkan Peta Gempa Indonesia 2010
Abstrak: Indonesia merupakan negara yang sangat rawan terhadap terjadinya gempa karena letaknya di antara empat lempeng bumi yang masih aktif. Gedung yang tidak memiliki ketahanan yang kuat terhadap beban gempa dapat bergoyang bahkan sampai roboh atau runtuh dan membahayakan nyawa para penggunanya. Gedung Student Center IPB merupakan gedung pusat kegiatan mahasiswa. Tujuan dari penelitian ini adalah untuk mengetahui ketahanan struktur atas gedung Student Center IPB dan membandingkan hasil evaluasi dengan kondisi lapangan (kondisi eksisting). Metode analisis gempa yang dilakukan dalam penelitian ini adalah metode statik ekuivalen. Hasil dari pemodelan struktur pada program ETABS menunjukkan bahwa semua komponen struktur yang terpasang, baik struktur kolom dan struktur balok pada kondisi eksisting telah memenuhi kebutuhan jumlah tulangan hasil evaluasi. Sehingga, dapat dikatakan bahwa Gedung Student Center IPB aman terhadap beban gempa berdasarkan Peta Gempa Indonesia 2010.

Judul: Characteristic of chili drying (Capsicum annum L.) as a natural dyeing cosmetic
Abstrak: Chilli (Capsicum sp.) contains carotenoids, which are a group of natural pigments consist of red, orange or yellow color. Carotenoids can be dissolved in lipid so that they can be applied to oil-based cosmetic ingredients. Therefore, chilli is potential to be developed as cosmetic colorants. However, pungency of red chili needs to be removed because it is irritating and it provides stinging sensation to skin. Red chilli was investigated as a potent material for a cosmetic colourant in this research because it has a nice uniform red color and has a pungency level less than cayenne pepper. The purpose of this research was to investigate the influence of blanching on drying characteristics of red chilli using a tray dryer, determine the proper time of chili blanching in sodium bisulfite solution, examine color changes stability of red chili powder as a cosmetic dye, and analyze the effect of oleoresin extraction on color and pungency level of red chili powder. The results showed that blanching could affect the drying characteristics. Blanching the chilli for 9 minutes prior drying could speed up the drying rate of chilli and thus the drying time, therefore, the chilli achieved the desired moisture content fast. Sodium bisulfite solution of 0.2%, used as the blanching media, could maintain the color well. However, longer time of blanching might cause several pigments soluble in the blanching media. Blanching the chilli for 9 minutes was able to maintain red color after the stability tested and after extraction of oleoresin. Therefore, blanching red chilli in a solution of 0.2% sodium bisulfite for 9 minutes prior drying is concluded as the best treatment to retain the color of red chilli powder
