Hak Anak Angkat Dalam Hukum Keluarga Islam di Indonesia

This research states that in Islamic law adopting a child is a good act, which helps adopted children get a proper education. The right to a proper education for adopted children is one of the main goals of adoption, this welfare is one of the rights that must be provided by adoptive parents. In general, implementing the above rights of children is an obligation and joint responsibility of the government and society. The phenomenon that occurs in Indonesia is that the educational rights of adopted children have shifted to utilization, due to several factors, one of which is economic. The aim of this research is to strengthen previous research, and examine further the shift in the educational rights of adopted children and look at the factors that result in non-fulfillment of adopted children's rights in Indonesia. This research uses an approachsociological normative  with the nature of the researchanalytical descriptive. The results of this research found several factors that resulted in a shift, even not being given the rights of adopted children, such as: f In fact, in Islam, adopting a child is a good act but over time it becomes exploitative.

Investigation of Nonlinear Dispersive and Dissipative Structures in Dense Plasmas

Quantum effects have been investigated in highly dense non relativistic, relativistic and ultra-relativistic plasmas. Various issues have been brought under consideration right from the Alfven solitary structure in non-relativistic, relativistic and ultra-relativistic electron-ion degenerate quantum plasmas. The full set of nonlinear QHD equations for a relativistic degenerate electron-ion plasma is used to investigate circularly polarized Alfven waves via the Zakharov equations. The solitary structures in non-relativistic and ultra-relativistic degenerate quantum plasmas are discussed by applying the Sagdeev potential technique. Also, we have studied obliquely propagating electromagnetic excitations in dissipative in the presence of relativistic and quantum effects. In this regard, relativistic quantum magnetohydrodynamic model and reductive perturbation technique is incorporated to study the linear and nonlinear magnetoacoustic modes in non-relativistic and ultra-relativistic electron-ion plasma. Also the effects of electron concentration, obliqueness and the magnetic field strength on the shock structures are investigated to both fast and slow modes.
