Judul: The Substitution of Soybean Meal by Butterfly Leaf (Bouhinia purpurea L.) in Ration Kind of Pellet Towards Male Rabbit off Weaning Performance.
Abstrak: The high quality ration supply has getting hindrance because influence of the price of ingredients are expensive, mainly the protein source like soybean meal. In Indonesia the supply of soybean meal is under requisites because of that we still import it, which made the price, are expensive. Because of the reason, we need to, find alternative ingredients, which came from forage. Why, because rabbit can used protein from forage efficiently. The Butterfly leaf is one of kind leguminous which can be useful for feed because the contain of crude protein is 23.34%, but the butterfly leaf contain 1.82% tannin which can caused feed restriction factor, because of that needed attention to utilize of butterfly leaf

Judul: Dry Matter Digestibility, Protein Digestibility and Nitrogen Retention of Weaning Local Male Rabbit on Substitution Soybean Meal with Bauhinia pururea L.
Abstrak: Bauhinia purpurea L. is a potential legume for rabbit fodder, it contains protein 21.l3%. Rabbit is one of a meat source originating from animal. because rabbit is a prolific animal and easy to rared. Twenty five weaning local male rabbit with average body weight 853 ± 117 gram were used. The aim of this experiment are to recognize the Bauhinia purpurea L. effect that may subtitute soybean meal as a source protein, by detennining the dry matter digestibility, protein digestibility ang nitrogen retention. Completely Randomized Design was used in the experiment. It consisted of five treatments and four replications. The composition of the treatment rations were soybean meal, Bauhinia purpurea L. and concentrate 60%(yellow com 24%, rice brand 12%, wheat brand 20%, coconut oil 2%, CaC03 1% and premix 1%). The ratio of soybean meal: Bauhinia purpurea L. in the diet were (Rl) 40%:0%, (R2) 30%: \0%, (RJ) 20%:20%, (R4) 10%:30% and (RS) 0%:40%. The result showed that the treatment did not significant influence dry matter digestibility, protein digestibility and nitrogen retention. Bauhinia purpurea L. can be used until 40% in the rabbit ration. Key word : Bauhinia purpurea L., soybean meal, dry matter digestibility, protein digestibility, nitrogen retention

Judul: Analisis Dinamik Struktur Gedung Terhadap Beban Gempa (Studi Kasus Tower Altiz – Tangerang Selatan).
Abstrak: Penelitian ini bertujuan untuk melakukan pemodelan gedung, menganalisis besarnya periode getar dan kekakuan yang dimiliki gedung, menentukan mode shape dan partisipasi massa, serta menganalisis besarnya gaya geser dasar gempa. Objek penelitian adalah Tower Altiz. Prosedur penelitian mengacu kepada SNI 1727-2013, SNI 1726-2012, SNI 2847-2013, dan PPURG 1987. Berdasarkan hasil penelitian, pemodelan Tower Altiz telah berhasil dilakukan. Periode getar yang dialami Tower Altiz adalah 2.735 detik. Mode shape dari Tower Altiz telah berhasil didapatkan. Untuk besarnya partisipasi massa pada arah x yang lebih dari 90 %, didapat pada mode ke-10, sedangkan untuk partisipasi massa pada arah y didapat pada mode ke-11. Gaya geser dasar statik (Vstatik) sebesar 11359.164 kN sedangkan besarnya gaya geser dasar dinamik (Vdinamik) 8339.260 kN untuk arah gempa-x dan 7722.238 kN untuk arah gempa-y. Faktor skala desain untuk gaya geser dinamik (Vdinamik) sumbu-x adalah 1.15, sedangkan untuk sumbu-y adalah 1.25. Besarnya gaya geser dinamik (Vdinamik) yang diperoleh untuk sumbu-x dan sumbu-y adalah 9655.289 kN.
