Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.

Judul: Perilaku Dinamis Model Mangsa-Pemangsa Tipe Gause yang Diperumum dengan Waktu Tunda Pemanenan Konstan
Abstrak: There are several mathematical models to describe prey-predator events. One model that has many applications is the generalized Gause type prey-predator model by considering a time delay and a constant harvesting parameter in both prey-predator populations. We performed stability analysis to both models without time delay and with time delay. For the model without time delay, we obtained three equilibrium points with one is spiral stable, while model with time delay possesses equilibrium points which can be either spiral stable or spiral unstable. In addition to the model with time delay, when the value of time delay increases, this causes the appearance of a limit-cycle and supercritical Hopf bifurcation occurs when the equilibrium stability change from spiral stable to spiral unstable.

Abstrak: In this paper we discussed a predator-prey model by considering a time delay to predator population and constant rate of harvesting in both predator and prey populations. We performed stability analysis to both models with and without time delay. For that without time delay we obtained two equilibrium points which are saddle for the case and spiral stable or node stable in another case. For the case of model with time delay, there are two equilibrium points which are saddle and spiral stable or saddle and spiral unstable in another case. Time delay parameter may result in the existence of limit cycle and Hopf bifurcation.

Judul: Sintesis 3-Benzoil-7-hidroksiflavon dari Resorsinol
Abstrak: Flavonoid is the most abundant naturally-occuring polyphenolic compound with C6-C3-C6 carbon skeleton. Flavones is a group of flavonoid having a broad bioactivity spectrum. In this experiment, 3-benzoyl-7-hydoxyflavone was successfully synthesized via 2-steps from resorcinol. In the first step, resorcinol was acetylated with AcOH/ZnCl2 producing resacetophenone with 89% yield. Subsequently, benzoylation and rearrangement of resacetophenone using 2 equivalent of benzoyl chloride and 7 equivalent of K2CO3 in acetone produced 3-benzoyl-7-hydroxyflavone with 62% yield. Synthesis of 3-benzoyl-7-hydroxyflavone from resorcinol provided evidence for new reaction mechanism of flavon formation without Baker-Venkataraman rearrangement proposed by several previous researchers. All products in this study has been characterized spectroscopically.

Judul: Dynamical System of Hepatitis B in Three Groups with Vaccination
Abstrak: The aim of this study is to modify the hepatitis B transmission model in three age groups involving vaccination from the model conducted by Zhoe and Zhang.The method used is to analyze the stability of the fixed point and its basic reproduction number (R_0). Performed stability analysis and numerical simulation to see population dynamics. Next, a sensitivity analysis of the parameters was carried out to see its effect on R_0. From the analysis obtained two fixed points, namely non-endemic and endemic fixed points. Non-endemic fixed points are locally asymptotically stable if R_0 <1 Meanwhile, the endemic fixed point is locally asymptotically stable if R_0 > 1. Hepatitis vaccination affects the number of susceptible population, because the more successful the vaccination, the smaller the number of susceptible populations so that the smaller the population will be infected.

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.
