Judul: Analisis Ketahanan Struktur Atas Rumah Instan Sederhana Sehat dengan Perhitungan Beban Gempa Berdasarkan SNI 03-1726-2012
Abstrak: Proyek pembangunan rumah instan sederhana sehat (RISHA) dua lantai mengacu kepada pedoman modul RISHA yang memuat standarisasi ketahanan struktur terhadap beban gempa berdasarkan SNI 03-1726-2002. Tujuan penelitian adalah menganalisis ketahanan struktur bangunan terhadap beban gempa berdasarkan standar yang berlaku. Nilai gaya geser dasar sebesar 8.392 kN dalam arah sumbu X dan arah sumbu Y. Dari hasil analisis diperoleh nilai tersebut telah melebihi dari persyaratan berupa 85% dari gaya geser dasar yang dihitung sehingga memenuhi SNI 03-1726-2012. Simpangan antar lantai yang terjadi akibat beban gempa telah memenuhi persyaratan karena nilainya lebih kecil dibandingkan simpangan antar lantai ijin. Ketahanan sambungan struktur antar panel RISHA memiliki kuat tekan ultimit sebesar 2105.8 kN dan gaya geser ultimit sebesar 13926.9 kN. Nilai tersebut lebih kecil dibandingkan kuat tekan perlu dan kuat geser nominal dari panel RISHA. Dengan demikian sambungan memenuhi syarat SNI 1729-2015.

Judul: Analisis Struktur Atas Gedung Rusunawa Putri IPB Terhadap Beban Gempa dengan Metode Statik Ekuivalen berdasarkan Peta Gempa tahun 2010
Abstrak: Struktur atas gedung terdiri dari tiga bagian yaitu kolom, balok dan pelat.. Penelitian ini bertujuan untuk menganalisis struktur atas gedung Rusunawa Putri IPB terhadap beban gempa serta menghitung hasil analisis gaya menggunakan metode statik ekuivalen. Permodelan gedung dan analisis pembebanan menggunakan software ETABS 9.7.2. Analisis kinerja struktur dilakukan berdasarkan SNI 1726-2012 dengan menggunakan metode respon spektrum. Dari hasil perbandingan pada tiap kolom yaitu kolom K1, K3, dan K4 kondisi eksisting selalu lebih besar dari kondisi evaluasi yang berarti aman. Tulangan lentur balok pada kondisi eksisting lebih besar dari tulangan lentur hasil evaluasi. Hal ini menunjukan balok yang dipakai saat ini tergolong terlalu besar. Semakin besarnya simpangan yang terjadi tiap kenaikan lantai dipengaruhi oleh semakin kecilnya kekakuan tiap kenaikan lantai Simpangan ini terjadi karena adanya gaya yang terjadi di tiap lantainya Simpangan terbesar terjadi pada lantai 5 dengan besar simpangan di sumbu-x mencapai 15.6 mm dan simpangan di sumbu-y hanya mencapai 12mm.

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
