Pemberlakukan syariat Islam banyak mendapatkan kritikan karena dianggap berpotensi melanggar Hak Asasi Manusia sebagaimana pemikiran Bassam Tibi. Namun demikian, hal ini berbeda dengan pandangan Muhammad Arkoun dan Hasan Asy-Syarqawi yang menerima pemberlakuan nilai-nilai kemanusiaan dalam ajaran hukum fiqh/Islam untuk ditransformasi ke dalam pembangunan hukum nasional. Berdasarkan permasalahan tersebut, kajian ini dapat dirumuskan sebagai berikut, bagaimana penegakan nilai-nilai kemanusiaan dapat diwujudkan dalam pembangunan hukum di Indonesia. Adapun jenis pendekatan kajian ini adalah kajian politik hukum yang meneliti nilai-nilai fikih kemanusiaan dalam pembangunan hukum di Indonesia. Hasil penelitian menyebutkan bahwa sejarah pertumbuhan dan perkembangan fikih/hukum Islam sangat terkait dengan dinamika kehidupan aktual dari manusia, bahkan eksistensi hukum ditentukan dengan kepentingan hidup manusia sebagaimana pandangan pakar hukum Najmuddin Atu-Tuhfi dan Philip K Hitti. Ajaran-ajaran hukum Islam memiliki oreintasi untuk menjawab masalah-masalah aktual kemanusiaan sebagaimana Nabi Muhammad saw telah dipratikkan Nabi dan penerusnya. Nilai-nilai kemanusiaan ini kemudian mendapatkan momentunnya yang baik ketika hak asasi manusia menjadi kebijakan umum dalam Dekralasi Universal Hak Asasi Manusia (DUHAM). Dalam sistem bangunan hukum di Indonesia, unsur hak asasi manusia tidak boleh dinafikan dan juga sekaligus unsur kekosongan hukum juga harus diperhatikan, sehingga eksistensi hukum yang lahir dari norma agama atau budaya masyarakat dapat diakomodir sebagaimana regulasi hukum yang berlaku di Indonesia.

This paper presents an approach of the Ehrlich ascities tumor growth modelling based on the logistic equation with diffusion. This model is constructed by using the concept of the reaction-diffusion equation. Besides that by using the principle of the travelling wave, a model equation with diffusion at tumor cell growth can be formed into the two non linear differential equation system. Then the equilibrium points of the non linear system will be obtained so that the stability of the model can be analized.

This paper proposes the relation between nonlinear systems with LPV systems (Linear Parameter Varying systems) where the non-linear systems can be described as LPV systems. Based on the LPV systems description, the nonlinearity of the systems is represented by parameters varying. Local properties of nonlinear systems are presented. It is assumed that all the conditions for the existence and uniqueness of solutions have been met. It is also assumed that the origin is a stationary point. Then, we will discuss how to analyze the stability of non-linear systems using the LPV systems approach. Furthermore, the bounds of parameters to ensure the asymptotic stability of nonlinear systems are given. To verify the proposed method, numerical simulations are demonstrated Â

. In this paper, we proposed the stability analysis of networked control system with time delay. Delay in a network is something that can not be avoided when transmitted digital data over control devices. Network control system is discussed here consists of clock driven sensor, event driven controller, actuator, and plant. In the network control system usually contains delays and sampling period with effect the system stability. Stability region in a network control system can be represented through the relationship between Maximum Allowable Transfer Interval and sampling period.

The logistic growth model with time delay has developed from the classical logistic model, where as in the growth logistic model with time delay, the growth process delay from a population is calculated. This delay cause population decrease then increase so oscillation appears in population growth. So, the solution is not a monotonous function. The result of analysis indicate that the logistic growth model with time delay have two equilibrium points. Each equilibrium points is analyzed for their stability based on time delay variation on the population growth. The longer time delay in the population growth can cause the unstable growth, hence the population decrease and become extinct.

tability the discrete chaotic systems is interesting to be discussed, given that chaos is closely related to random and irregular state. Stability of discrete chaotic system can be obtained using impulsive control law and applying Lyapunov stability theory. So it can show sufficient conditions for the design of impulsive controllers and globally exponentially set-stable can be reached. Based on the results of the impulsive control, it is seen that the behavior of chaos in a discrete chaos system which originally the trajectory are irregular, can be control and become stable, and there is a globally exponentially attracting set earned in the system. The numerical simulation on the discrete chaotic system is presented to illustrate the effectiveness of the obtained results from control impulsive.

The principle_work of polyvascular clepsydra water clocks is to make the constant flow on the last vessel. A viscosity dominated case can influence a liquid flow in this clepsydra, beside the number of the vessel which build this clepsydra, will influence a constant flow duration. The increasing the number of the vessel will increase the duration of the constant flow. A case study at PT Tirta Sidatama  is given toverify the principle_work of this clepsydra. Â

In this paper we propose diophantine equations with the form  and . These equations has integer solutions which can form Fibonacci numbers and Lucas numbers. Integer solutions of the Diophantine equations in the form of Fibonacci number and Lucas number are determined by using recursive formula, Binet’s Formula, and the most important is identity of Fibonacci numbers and Lucas numbers.

The nitrogen dynamics model  related to algae growth is proposed. The form of the model is nonlinear differential equation system. From these model, the stability of the equilibrium point is disscussed. The stability is analized through the eigen values of the Jacobian matrix that is obtained from linearized system. From the simulation results is found that ammonia-nitrogen, nitrite-nitrogen, and nitrate-nitrogen concentration will achieve to a certain value. The changed of ammonia-nitrogen, nitrite-nitrogen, and nitrate-nitrogen concentration are effected by the algae density. If the alga density increase then the ammonia-nitrogen and nitrite-nitrogen concentrations will increase but the nitrate concentration will decrease. Â
