Judul: Kajian elongasi dan aklimatisasi pada kultur in vitro Aquilaria beccariana van Tiegh
Abstrak: The world's demand of eagleivood and its derivate product since 1970's. Based on BPS (2000) in Asgarin (2002), indonesian export have reached a peak in 2000 in a number of 456 tons. with the production value is US$ 2.2.00.000, then in the 2000-2002 have decreased significantly until 30 tons with the total ofproduction US $600.000 With a decrease of export capacity of eaglewood bring a new fact that in Indonesia for its density only <I tree per hectare, Soehartono and Mardiastuti (2003). In 2004, the CITES Co~nmissionh ave stated for trees that produce Gaharu genus Aquilaria and Gyrinops sp as a plant is Appendix 11 on CITES. The >ustainaule effort to keep gaharu with ex situ method have been done, but there are some obstacles on implementation. In vitro kulture is one ofthe alternative method for fastcn the recovey of Gaharu population in nature. This research is aim to gct the elongation method and optimal acclimatization for in vitro kulture with adding combination of auksin and sitokinin.

Judul: Aplikasi bakteri Methylobacterium sp. terhadap  pertumbuhan dan perakaran tunas gaharu (Aquilaria malaccensis Lamk) hasil In-vitro
Abstrak: Aquilaria malaccensis is forest plant species that have substances of resin and economic valuable. For many people and industry, resin usually called "gaharu", used for medicine like stomachache drug, asphyxia, pregnant lasing and rheumatism; industrial raw material of parfume and cosmetic also complement of custom need. In technology progress and increasing of agarwood exploited make agarwood commodity has been decrease. So, by CITES its classified as one of the scare crop (Appendix II). Various method propagation had been conducted including breeder of vegetatif in-vitro culture (biotechnology) with it varioous modification treatment of griwth subtance regulator, condition of other growth factor and also environment bur rooting agarwood/gaharu still being one of many problems in this propagation method. Bacterium application of Methylobacterium sp. which have been reported to yield phytohormon or growth subtance regulator that needed for growth and development plant that hpefully can be one of alternative way to overcoming constraint in culture in-vitro . The aim of this research are to study the influence, to decide the strain and to decide the efective soaking time of Methylobacterium sp. for growth and rooting of Aquilaria malacceensis (gaharu) shoot

Judul: Transisi Fasa Materi Hadronik ke Materi Kuark pada Inti Bintang Neutron.
Abstrak: Bintang neutron terdiri dari beberapa lapisan yang disusun oleh materi nuklir yang berbeda dengan kerapatan yang semakin tinggi ketika mendekati pusat bintang. Inti luar bintang neutron disusun oleh materi hadronik (nukleon, lepton, dan hyperon), sedangkan inti dalam bintang neutron disusun oleh kuark-kuark bebas (up, down, strange) yang saling berinteraksi. Tujuan penelitian ini adalah mempelajari bagaimana transisi dari inti luar ke inti dalam bintang neutron dengan menggunakan pendekatan RMF (Relativistic Mean Field) untuk materi hadronik dan CIDDM (Confined Isospin Density Dependent Mass) untuk materi kuark. Tekanan transisi diperoleh ketika potensial kimia barion materi hadronik dan materi kuark bernilai sama. Nilai tekanan transisi dengan parameter SU6-TM1 sekitar 87 MeV/fm3 dan diperoleh massa maksimum bintang neutron yaitu 1.92M dengan jari-jari sekitar 8.62 km. Nilai tekanan transisi dengan parameter SU6-G2 sekitar 53 MeV/fm3 dan massa maksimum bintang neutron yaitu 1.88M dengan jari-jari sekitar 8.16 km. Jenis transisi fasa adalah orde satu ditandai dengan diskontinuitas dalam kerapatan energi (adanya mixed phase). Parameter-parameter pada model nuklir yang digunakan menyebabkan perbedaan kekakuan persamaan keadaan (EOS) dari materi hadronik dan materi kuark sehingga nilai tekanan transisi dari fasa hadronik ke fasa kuark juga berbeda.
