Judul: Aplikasi Mikrokapsul Sinbiotik dengan Dosis Berbeda Melalui Pakan pada Pemeliharaan Ikan Mas (Cyprinus carpio)
Abstrak: This study aimed to determine the administration of synbiotic microcapsulated doses by feed on survival rate, growth performance, and immune response of carp juvenile (Cyprinus carpio). The amount of the fish is 30 with an average weight is 4,81±0,07 g were reared in hapa net sized 100x100x100 cm3 for 30 days. This study was conducted in Compeletely Randomized Design (CRD) consisting of 4 treatments and 3 replications, including administration of synbiotic microcapsulated in feed with different doses (0.5 %, 1 %, 2 %) and control. The observe parameters namely survival rate, specific growth rate, feed conversion ratio, eritrocyte total, leukocyte total, total bacteria in the intestine, and water quality. The result of this study showed that the administration of 1 % synbiotic microcapsulated had the best growth performance in carp juvenile.

Judul: Pemberian sinbiotik dengan dosis berbeda untuk meningkatkan kinerja pertumbuhan dan sistem imun benih ikan patin Pangasius sp.
Abstrak: Catfish (Pangasius sp.) is one of freshwater commodity which has high economic value. One of problems which often faced by the cultivator in catfish production is the problem of diseases. The aim of this research is to evaluate the effectiveness of giving synbiotic with different doses in feed to increase the growth and immune responses on catfish fingerlings. The probiotic used is NP5 (Bacillus sp.), and the prebiotic used is oligosaccharides extracted from sweet potato Sukuh variety. The catfish fingerlings used has average of weight 0,43±0,06 gram and average of length 3.55±0.17 cm, and it was kept as many as 3 fish/liter in aquarium which (30x25x25) cm3 and filled with 10 liter of water. This research has been done in 4 treatments namely K (control), A (adding 0,5 dose of synbiotic), B (adding 1 dose of synbiotic), C (adding 2 dose of synbiotic). The result study shows that giving synbiotic in feed with different doses can give different increasing of growth and immune responses in catfish fingerlings. The catfish fingerlings given 1 dose of synbiotic showed the best increasing of growth and immune responses compared to the other treatments.

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.
