Judul: Analysis of the Upper Structure of the IPB Leadership Dormitory Building Against Earthquake Loads with the Equivalent Static Method
Abstrak: Indonesia memiliki lokasi yang rawan terhadap gempa sehingga gedung-gedung yang berada di Indonesia harus didesain tahan gempa. Penelitian ini dilakukan untuk mengetahui ketahanan struktur atas gedung terhadap beban gempa dengan peraturan terbaru. Komponen utama struktur atas dimodelkan pada ETABS. Hasil pemodelan struktur menunjukkan bahwa pola ragam pertama mengalami translasi ke arah Y, kedua mengalami translasi ke arah X, dan ketiga mengalami rotasi. Partisipasi massa juga telah mencapai 90% pada pola ragam getar ke-26 di arah X dan ke-22 di arah Y. Simpangan antar tingkat dari struktur gedung dikatakan aman karena nilainya berada dibawah simpangan yang diizinkan. Hasil analisis menunjukkan balok yang terpasang memiliki jumlah dan diameter tulangan yang sesuai dengan hasil evaluasi, struktur dinding geser juga dinyatakan aman karena dapat menahan gaya aksial, momen, dan geser. Pada struktur kolom terdapat beberapa kolom yang mengalami kegagalan yang disebabkan oleh kebutuhan tulangan melebihi maksimum dan tidak mampu menahan gaya geser. Kolom diperlukan penambahan kekuatan dengan melakukan metode RC jacketing.

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: Perubahan Warna Ikan Maskoki Carassius auratus yang Diberi Pakan Berkarotenoid dengan Lama Pemberian Berbeda
Abstrak: Goldfish or “maskoki” is a beautiful freshwater ornamental fish. Price of goldfish depends on several factors, one of them is the body color. The body color of goldfish depends on carotenoid contain on its feed. Carotenoid source must be added into the goldfish feed that used for intensive rearing. Unfortunately, the price of commercial feed that contain carotenoid such as spirulina, relatively more expensive than common commercial feed. So, it require a combination between common commercial feed and those which contain spirulina to lower the cost. Uniformed orange fish seeds, average body length 3.2 ± 0.28 cm and average weight 4.9 ± 0.9 gram fed common commercial feed and feed that contain spirulina as carotenoid source. Fish were fed three times a day with feeding rate 5% of its biomass on first 20 days of rearing and 4% on the next 20 days. Ratio feeding period of common feed : carotenoid feed in this research was: 1) 40:0 (fed common feed for 40 days and carotenoid feed for next 0 days), 2) 30:10, 3) 20:20, 4) 0:40. Percentage of color score evaluation was the total number of fish based on color criteria divided by total number of living fish times 100%. Color changing of goldfish that happened on application of feeding period with carotenoid feed for 40 days was orange-red as much as 93.10% and those which did not change orange color was 6.90%. Color changing that happened on application of feeding period with carotenoid feed for 20 days was orange-red as much as 58.33% and yellow-orange was 2.78% and those which did not change orange color was 38.89%. Color changing that happened on application of feeding period with carotenoid feed for 10 days was orange-red as many as 55% and faded 5% and those which did not change orange color was 40%. Color changing that happened on application of feeding period with carotenoid feed for 0 days was yellow-orange as many as 36.11% and faded 5.56% and those which did not change orange color was 58.33%. Carotenoid feed did not effect to weight and length growth rate and length differentiation coefficient. The best period of carotenoid feed for goldfish is 10 days that resulted color change to orange-red was 55% and best of R/C ratio.
