Judul: Disain Suatu Modul Tempat Penyimpanan Gabah Secara Curah di Bogor
Abstrak: Suatu modul tempat penyimpanan gabah secara curah diperlukan untuk membuat suatu disain dengan mempertimbangkan kebutuhan petani terhadap tempat penyimpanan, persyaratan fungsi dan persyaratan struktur dengan tujuan memperkecil kehilangan gabah selama penyimpanan. Di Indonesia, kehilangan gabah setelah panen diperkirakan sebesar 25 persen, di mana 4 persen diantaranya merupakan kehilangan pada penyimpanan tingkat petani. Analisa fungsi meliputi pendugaan suhu, kelembaban relatip (RH) dan kecepatan aliran udara di dalam tempat penyimpanan. Di samping itu juga didapatkan kemiringan lantai sebesar 30° dan pintu pengeluaran berukuran 80 cm x 25 cm. Pendugaan nilai parameter dari suhu, RH dan kecepatan aliran udara di atas dilakukan dengan pendekatan matematik. Analisa struktur meliputi analisa dan penentuan dimensi atap, rangka atap, kuda-kuda, dinding, tiang, lantai dan pondasi. Analisa fungsi dan struktur menghasilkan suatu disain modul tempat penyimpanan gabah. Disain tersebut terdiri dari gambar denah, gambar tampak samping dan depan serta gambar potongan, yang secara keseluruhan dan terperinci dituangkan pada gambar tampak dan detail. Untuk membuat modul tempat penyimpanan gabah berukuran 2.5m * 2.5 m * 3m dan berkapasitas 4 ton diperlukan biaya. kurang lebih Rp 100 000; berdasarkan harga bahan bangunan dan upah bulan Maret 1977.

Judul: Analisis dan Redesign Struktur Greenhouse Tipe B2 di Daerah Cikabayan Kabupaten Bogor
Abstrak: Greenhouse merupakan bangunan pertanian yang sering digunakan pada wilayah tropis. Desain greenhouse pada wilayah tropis harus memperhatikan kondisi panas saat siang hari. Penelitian ini bertujuan mengevaluasi greenhouse eksisting tipe B2 dan melakukan desain ulang struktur yang lebih efisien menggunakan Standar Nasional Indonesia serta menyusun rancangan anggaran biaya. Analisis struktur dalam penelitian ini menggunakan slope deflection method dan SAP 2000. Hasil analisis menyatakan bahwa kekuatan layan greenhouse eksisting overdesign pada kuda-kuda atas, kuda-kuda bawah dan kolom atas masing-masing sebesar 8640 kg, 15840 kg, dan 8640 kg serta terjadi beban geser masing-masing sebesar 533.98 kg, 1009.61 kg, dan 177.3 kg. Desain ulang struktur dilakukan pada batang kolom atas, diubah dari H 100 100 6 8 menjadi H 150 75 5 7, dan pada batang kuda-kuda atas diubah dari H 100 100 6 8 menjadi H 150 75 5 7. Batang kuda-kuda bawah diubah dari H 200 100 5.5 8 menjadi H 150 100 6 9, dan kolom bawah diubah dari H 125 125 6.5 9 menjadi H 150 150 7 10. Panjang kolom atas juga diubah dari 0.8 m menjadi 1.5 m dan atap single roof menjadi double roof. Biaya yang dibutuhkan untuk desain greenhouse adalah sebesar Rp613,247,347.00

Judul: Phylogeography and Species Limits in the Papuan White Snake (Micropechis ikaheka) (Reptilia: Serpentes: Elapidae)
Abstrak: Papua white snake, Micropechis ikaheka, has been distingushed into two subspecies M.i. ikaheka and M.i. fasciatus. However, due to lack of data on their morphology, distribution and ecology, both subspecies often ignored in scintific discussions and refers only byas , Micropechis ikaheka. This study was designed to document the differences between M.i. ikaheka and M.i fasciatus by using scales characteristics and reproductive organ or hemipenes. The study also examine, zoogeography, habitat, diet and cannibalism of both subspecies to better understanding the the ecology of one of the most venomous snakes in the world. This study consists of three topics with method and also different in the size samples, respectively. The first study is the histology and microtopography of the skin were studied using paraffin method and Scanning Electron Microscope (SEM). The second is the hemipenis were examined by following Myers and Cadle (2003), and Zaher and Prudente (2003). The third is the abdominal surgery was carried out to document diet type and the investigate phenomenon of cannibalism in the snake. Specimens for this study came from the collection from Museum Zoologicum Bogoriense (MZB) and Universitas Negeri Papua’s Laboratory (LZU). The research result also indicated that the markers of skin and hemipenis described the same structure and microornamentation in all M. ikaheka groups being compared. Based specimens examined morphological descriptions do not s support the further differentiation in Micropechis. In short, two markers that used in this study could not sufficiently indicate the differences in the level of species and subspecies of M. ikaheka. The study, however, were able to delineate zoogeography and skin color patterns, which fall into four groups: M. i. ikaheka; M. i. fasciatus. M. i. ssp. “intermediate”; and M. i. ssp “black”. This study also revealed that color variations did not overlap in their geographic distribution. It is therefore, it suggested that environmental factors may contribute to the skin color variations. It also assumed that habitat discontinuous and biogeography factors may also cause the loss of the connection between the original populations (vicarians) or follow colonization events (dispersal). The examined of 22 stomach contents of M. ikaheka shows this species is carnivorous, and prey on vertebrates such as amphibians, fish, reptiles, and Mammals. These snakes are opportunistic predators since they prey on all that can be captured, but mainly reptiles (61.5%), followed by mammals and fish (both 15.4%), and amphibians (7.7%). Although categorized as terrestrial animal, the diet study showed that M. ikaheka snakes often go into the water to hunt for fish (the sample from Yapen island), including eel (the sample from Aru island). Based on prey items indentified, there is evidence that M. ikaheka is cannibal. At this time, there still no record on reason for cannibalism, but it is assumed that cannibalism was due to competition between populations and means to control population.
