Judul: Pertumbuhan dan perkembangan anter Solanum khasianum Clarke dalam kultur in-vitro
Abstrak: 'Ibjuan penelitian ini adalah untuk mempelajari pertumbuhan dan perkembangan anter Sohwn khasianwn Clarke dalam kultur in-vitro yang diharapkan mampu menghasilkan tanaman androgen. Serangkaian peroobaan meliputi praperlakuan bunga, seleksi medium kultur, jenis dan taraf konsentrasi auksin atau sitokinin, taraf konsentraSi sukrosa dan glutamin serta suhu prakondisi kultur telah dilakukan. Praperlakuan pendinginan bunga menghilangkan sifat lengket bunga sehingga memudahkan pensucihamaan (sterilisasi) bunga tetapi tidak berpengaruh terhadap pola perkembangan kalus. Komposisi dan bentuk fisik medium kultur berpengaruh terhadap persentase pembentukan kalus. Pembentukan kalus dari anter mutlak memeflukan auksin dan kalus ini sulit diregenerasikan menjadi tanaman.

Judul: Analisis Struktur Box Girder Jembatan Fly Over Rawabuaya Sisi Barat Terhadap Gempa
Abstrak: The Rawabuaya flyover bridge is the solution that is offered by the local government to overcome the traffic jam that often happens in the Rawabuaya area. It has an extremely vital function to disentangle the traffic congestion; therefore the structure must be strong in holding the on-going load, specifically the seismic load. The seismic load is dangerous to a structure because it has period that causes the structure to repeatedly shaken. If the movements happened continually, the structure will collapse ― depending on how much earthquake load that is being loaded on the structure. Therefore, it is essential to conduct an structure analytical on the earthquake resistance level of Rawabuaya flyover bridge based on the "Standar Perencanaan Ketahanan Gempa Untuk Struktur Bangunan Gedung dan Non-Gedung" RSNI 03-1726-2010 and "Peta Zonasi Gempa Indonesia 2010" to know further about the on-going deformation. This research is done thoroughly by recognizing the maximum forces in the combination of ultimate loads based on the most recent rules of encumbering, including the rules regarding the seismic load. The maximum forces in the combination of ultimate loads will then compared with the forces' nominal values, especially those that related to the seismic load. From the research, it can be concluded that the values of maximum forces in the combination of ultimate loads have the combined seismic load that works on the upper structure of box girder as well as on the structure beneath the pier of Rawabuaya flyover bridge with a maximum momentum values of 800300,80 KNm that applies to Pier P6B with the combination of the singular ultimate load, the additional dead load, the prestress load, and the “T” truck load. Impairment to the structure is bound to happen if the combination of ultimate load is forced to work continuously on the Rawabuaya flyover bridge. Meanwhile, the result of the compared maximum forces in the combination of ultimate load with the values of nominal forces indicates that the Rawabuaya flyover bridge has a large amount of seismic load with 10% difference. It means this structure can resist 90% of ultimate seismic load, which requires the usage of reinforcements on the upper structure of box girder as well as the on the structure beneath the pier to increase the concrete stress power and the tendon on the upper structure of box girder to increase the tensile of the concrete.
