The scholarship is one of the funding schemes of study in an education system. Various models and names of scholarship schemes are offered on terms that have been determined by the scholarship provider. The essence of these conditions is the trust and confidence of the funders of the scholarship recipients and is projected to complete the study period as per the allocated funds. In general, funders are very concerned about the issue of academic qualification as one of the main indicators. However, for prospective students who wish to pursue higher education from coming from orphaned families and from less financially qualified families, with good academic qualifications, not yet a parameter in the selection process of scholarship recipients. Based on this fact, this problem would like to find solution in this research and submitted the selection model of scholarship with fair decision approach. This study aims to design a fair decision-making system as a tool for selection of scholarship recipients that prioritize the values of justice by prioritizing scholarship recipients from among orphans and poor. This research proposes two methods: Fuzzy Mamdani and weighting method, with 4 input parameters which are used as variables: children status and economic level, residence condition, children achievement and family dependent. Simulation testing performed by considering the parameters set is a more effective and efficient decision model for the prospective scholarship recipients. To obtain a competent recipient, then the screening process by ranking to be declared passed the selection and received as the recipient of scholarship in accordance with the number of quotas provided. This selection model becomes an alternative and provides opportunities for orphans and the poor to continue higher education and improve the human resource index as well as meet national education goals.

Mathematical Modeling of SEIR Type to Controlling Diabetes Mellitus Disease Using Insulin Asmaidi Asmaidi; Eka Dodi Suryanto
Jurnal Inotera Vol. 2 No. 2 (2017): July-December 2017
Publisher : LPPM Politeknik Aceh Selatan

In this research the developed model is SEIR type mathematical modeling using insulin as a form of treatment. SEIR is abbreviation of susceptible (S), exposed (E), infected (I) and recovered (R). Expected goals include to making mathematical models for spread of diabetes mellitus, fixed point determination and basic reproduction number, stability analysis of fixed point, simulation of fixed point stability, simulation of population behavior to know the strategy of controlling diabetes mellitus. Analytical and numerical analysis results were obtained two fixed points, namely the point of no disease (disease-free equilibrium) and the point of disease (endemic equilibrium). Stability analysis of each fixed point indicates that the fixed point there is no stable disease when R0 < 1, whereas the fixed point there is stable disease when R0 > 1. Numerical simulations show that, with reduced Susceptible population contact rate with the exposed population causing to decrease, so the spread of the disease does not appear in the population. These results indicate that one strategy of controlling the spread of diabetes mellitus can be done by reducing the rate of contact susceptible population with eksposed.
