Judul: Drought tolerance transgenic hot chilli line carrying  P5CS transgene encoding key enzyme for proline biosynthese : plantlet  regeneration and characterization.
Abstrak: The objectives of this experiements were to evaluate effects of drought stress at vegetative stage on growth, yield and leaf proline content of hot pepper. Drought stress was conditioned by watering plants every five days during the period of 21-54 days after planting (DAP). Results of the experiment indicated that drought stress reduced plant heigh, branch numbers, stem diameter, root length, shoot, root and biomass dry weight and fruit yield.

Abstrak: Disertasi ini ditulis berdasarkan hasil-hasil percobaan yang menngarah pada seleksi beberapa kultivar unggul nasional dan mekanisme toleransi kacang tanah terhadap stres kekeringan pada fase vegetatif dan generatif. Berdasarkan hasil seleksi dan mekanisme tersebut dilakukan teknik rekayasa genetika untuk mendapatkan tanaman yang toleran kekeringan melalui mekanisme over ekspresi gen P5CS - penyandi ensim kunci biosintesis prolina., This dissertation was written based on results of experiments directed toward identification of drought tolerance among peanut cultivars grown in Indonesia and determination of the tolerance mechanisms. Subsequently, genetic engineering was employed to develop drought tolerance transgenic plants (peanut and tobacco) through over-expression of P5CS gene encoding the key enzyme for proline biosynthesis.

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
