Judul: Model Dinamika Simpanan Karbon dari Perubahan Tata Guna Lahan Kawasan Hutan di Sulawesi Selatan
Abstrak: Landuse change and forest degradation occur in many areas in Indonesia, including South Sulawesi that may affect carbon stock. Carbon stock decrease can be overcome by carbon mitigation. Carbon stock dynamic should be calculated to determine the amount of carbon in atmosphere that can be absorbed by forest. The objectives of this research were to estimate changes of forest cover and carbon stock in South Sulawesi and to build scenarios of carbon emission mitigation in South Sulawesi. The method used for building the model was system approach, which would explain the comparison of landuse change and its carbon sink rate in research location. The decrease rate of forest area was 7 362 ha/year. Carbon stock in 2006 was 539 mega ton C and fell by 15 mega ton C in 2050. There were four scenarios to mitigate carbon in this research: law enforcement, conservation province, tree planting on critical land, and forest reclamation after mining. The scenarios can prevent the rate of decreasing even increase carbon stock in South Sulawesi.

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: 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.

Judul: Pendugaan Hazard Rate Gempa di Provinsi Aceh dengan Metode Single Decrement
Abstrak: Hazard rate has a significant effect on the earthquake forecasting. If the hazard rate is given then the joint density distribution of earthquake occurrences can be identified. Therefore we need a parametric model that accurately estimates the hazard rate. In this paper a method to estimate the hazard rate at a point 􀝐������􀬴������ is discussed. The method used is single decrement method. There are two approaches that can be used to estimate the hazard rate using the method of single decrement, those are likelihood approach and the moment approach. The likelihood approach requires an assumption on the distribution of the waiting time of earthquake occurrences. In this paper the distribution of waiting time of earthquake occurrences is assumed to be linear, exponential, and hyperbolic. Estimation of the hazard rate uses earthquake data in Aceh with power greater than or equal to 5 SR. The approach used is likelihood approach. Parametric model obtained from this method is expected to estimate the hazard rate accurately.

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.
