Mathematical Modeling of SEIR Type to Controlling Diabetes Mellitus Disease Using Insulin Asmaidi Asmaidi; Eka Dodi Suryanto

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.

Digital image (image) is another term for picture, as one of the multimedia components plays a very important role as a form of visual information. Image processing is a process that involves a lot of visual perception. A grayscale image is an image that has only one channel value in each pixel, in other words the values of Red, Green, Blue are used to indicate the intensity level. Pixel (Picture Elements) is the value of each matrix entry in the bitmap. This pixel is affected by the number of colors that can be displayed. Image improvement is one of the simplest and most attractive methods in digital image processing. Basically, the idea behind image improvement techniques is to bring out obscured details or just to highlight certain interesting features. Histogram Equalization/Histogram leveling is a histogram smoothing process, where the distribution of gray level values of an image is made evenly.

Effectiveness of the Application of Cooperative Learning Models Type Group Investigation on Discrete Mathematics Courses at Informatics Engineering Study Program of Polytechnic of South Aceh Asmaidi Asmaidi; Oktalia Triananda Lovita; Khairuman Azmi

The results of student learning in the Informatics Engineering Program in the Discrete Mathematics course showed unsatisfactory results. there were 40 students who took part in the lecture. Students who get D and E scores are 18 people. the value of students who do not pass reaches 45%. In addition, student activities during the course of learning are very passive. Students only receive material delivered by lecturers and are not actively involved in learning. The problem formulation in this study is how the learning outcomes and learning activities of students are taught using the cooperative learning model type Group Investigation and conventional learning models in Discrete Mathematics courses in the Informatics Engineering Study Program in South Aceh Polytechnic?. The purpose of this study was to find out the learning outcomes and student activities while learning using the Group Investigation model. This type of research is a pure experiment with random design, pre-test, post-test. Research procedures go through several stages, namely initial observation, preparation, implementation, evaluation, and final results. The research subjects were Informatics Engineering students of South Aceh Polytechnic Semester II consist of two group, namely classes 2A and 2B. The data in this study is the test value on sequence and number series materials; and the observation of student activities during the learning process. Data collection techniques used in this study were test questions and student activity observation sheets. The analysis technique used were t-test statistical data and percentage formula. The results of the final test data analysis in both the experimental class (2A) and the control class (2B) using the t-test of two parties at a significant level α = 0.05 were obtained and . So the relationship obtained or . It can be concluded that student learning outcomes with cooperative learning model Group Investigation type are better than learning without using cooperative learning model Group Investigation type (conventional model) in Discrete Mathematics courses especially in Sequence and Series sub material in Informatics Engineering Study Program South Aceh Polytechnic. The average percentage of student activity during the three meetings was 75.40% and was in the very active category.
