The planning carried out by the teacher is compiling learning tools. Learning devices that are arranged are learning tools that can make the learning process run well. Teachers must provide opportunities for students to play an active and creative role in exploring abilities in each learning process, in order to create a good learning process. One alternative that can be used by educators to su…
In general, a lot of discussion on the line discusses the symmedian point. This thesis discusses the reflection of trimedian and trisector. The discussion is about the side lengths of the symmedian and the area of the symmedian of triangle. The proof is done using a very simple method, namely by using the concept of the height line on the triangle and the trigonometric concepts of the trian…
This thesis discusses the comparison of the area of the symmedian triangle with the original triangle.

This research was motivated by the mathematics learning outcomes of grade VIIIB students of SMP IT Darul Huda Ukui which were still below the Minimum Completeness Criteria (KBM) with a percentage of 37,03% who reached the KKM in circle subjects. Build flat side space. The purpose of this study aims to improve the learning process and improve students' mathematics learning outcomes through the a…
This research is motivated by the 2013 Curriculum which requires students to be active in learning so that they are able to build their own knowledge and be able to solve contextual problems that facilitate mathematical problem solving abilities. The purpose of this research is to develop learning tools in the form of syllabus, lesson plans, and LKPD using the Problem Based Learning (PBL) …
This final project discusses combinations of Newton-Halley method for solving nonlinear equations. This method is obtained by modifying Taylor expansion, Newton method and Halley method. The convergence of the proposed method is proved analytically that the method has sixth order of convergence and their efficiency indexes are 1.431. At the end of the discussion, computational results of c…
This final project discusses about the dynamic behaviors of a Lotka-Volterra predator-prey model with predator cannibalism. The observed model consists of four equilibrium points. Simulation of the model is carried out with spesific parameters to describe the behavior and stability of the equilibrium points. Based on results of simulation, cannibalism has positive or negative effect depends…
This final project discusses about the predator-prey model with harvesting rate on predator. This model also use Holling II function. The model has three equilibrium points in which they are unstable. Simulation of the model is carried out to interpret the relationship between predator and prey . This is a review of Triharyuni and Aisyah [IOP Conference Series: Earth and Enviromental Scien…
This nal project discusses the pristine numbers. Pristine numbers can be determined by recursive divisors function. Using the recursive rule method in recursive divisor function, then it can be determined the pristine numbers form. A number is pristine if a(n) = n where a(n) recursive divisors function of n. The result of pristine numbers form are 2c; 2cq; 2cqr; 2cq2; 2cqrs; 2cq2r. This is…
This final project discusses the constancy of Haruki’s entry on the ellipse. Given two nonintersecting chords AB and CD on the ellipse and a point P on the arc AB remote from points C and D, let E and F be the intersections of chords PC,AB and PD,AB respectively. The value of AE · BF/EF does not depend on the position of P. The proof is presented by geometric transformations, using the …
