Abstract

Raskin Program is national program with aim to support impecunious household in fulfilling sufficiency of requirement of food and lessen burden of finansial through readying of rice subsidize. BPS have specified 14 ( fourteen) impecunious family criterion which become base of division of raskin. Household told impecunious if fulfilling one of the impecunious criterion. To analyze distributing of raskin conserning to the number of variable which is used in determining household receiver of raskin by logistics regression. Household owning highest probability accept raskin is household with floor is earth, residence wall type is bamboo, usage of facility defecate public, source of improtected wellspring drinking water, fuel to cook firewood, not capable to pay [for] the expense of medication, revenue of earnings of family head less than Rp 600.000,00 highest education of family head is Madrasah Ibtidaiyah, owning things which can be sold for the price of less than Rp 500.000,00

Abstract

In this paper we derived a modification of the model of waves evolution in two-directional spatial coordinates. Using KP equation as the basic model, we improved dispersive property in spatial x coordinate and named it as improved KP (iKP) equation. iKP has an exact dispersion relation in spatial x coordinate. Using this model, we derived second order regular waves and  analyzed the expression of Maximum Temporal Amplitude.

Abstract

A model of wave propagation in porous medium is derived, based on the pressure, giving a diffusive-like equation. The model is then solved numerically by a finite difference method. Taylor approximation is applied to the nonlinear term to obtain a diagonal dominant matrix corresponding to the finite difference equations, so that Gauss-Seidel iteration can used to solve the system of equations. As the result, over-damped wave is performed in this paper, related to quality of the medium.

Abstract

To measure of how close the ring is to being Artinian ring is used usually so called Krull dimention. In the case of noncommutative rings, the Krull dimention is measured on the lattice of ideals. In this situation, the lattice of  ideals is seen as a poset (partial ordered  set) and then the deviation of the poset is measured. This paper will describe, completely, deviation of posets including the deviation of product of two posets. Moreover, this paper also will present characteristic of poset which has a deviation and does not have.

Abstract

As guarantee in a life insurance is which caused by death. The death results loss of income of someone or the family. With the result that, a life insurance provides a payment of specified amount upon the death of a given life. There are two systems in this payment, that the insurance payable at the moment of death (continuing insurance) and the insurance payable at the end of the year of death (discrete insurance). If life table are uniformly distributed, so there is a relationship that an immediate payment is equivalent on the average to a payment of  at the end of the year of death.
