Abstract

Penelitian ini dilatarbelakangi oleh pemikiran bahwa untuk menghadapi tantangan perkembangan IPTEK diperlukan sumber daya yang memiliki keterampilan tinggi yang melibatkan pemikiran kritis, logis, kreatif dan kemampuan bekerjasama yang baik, tiga komponen kunci yang dinilai dalam berpikir kreatif adalah kefasihan (fluency), fleksibilitas (flexibility) dan kebaruan (novelty). Kefasihan mengacu pada banyaknya ide-ide yang dibuat dalam merespons sebuah perintah. Fleksibilitas tampak pada perubahan-perubahan pendekatan ketika merespons perintah. Kebaruan merupakan keaslian ide yang dibuat dalam merespons perintah. Untuk mengembangkan dan mengasah kemampuan kreativitas siswa, maka siswa harus diperkenalkan dengan masalah-masalah matematika yang terbuka yang memungkinkan memiliki cara-cara yang berbeda dalam penyelesaianya serta memiliki jawaban yang beragam atau bahkan memiliki banyak solusi benar sehingga mampu merangsang peserta didik untuk berpikir kreatif, karena dengan masalah-masalah matematika yang terbuka siswa diharapkan dapat mengaitkan antara konsep yang satu dengan yang lain dan menggunakannya dalam pemecahan masalah. Dalam memecahkan suatu masalah, terdapat informasi yang harus diolah dan diserap dengan baik agar masalah tersebut dapat terselesaikan, aktifitas menyerap, mengatur, dan mengolah informasi disebut, itu yang dikatakan sebagai gaya belajar. Banyak ciri perilaku yang merupakan petunjuk kecenderungan gaya belajar seseorang; yaitu gaya belajar visual, auditori dan kinestetik. Tujuan penelitian ini adalah untuk mendeskripsikan kreatifitas siswa dalam pemecahan masalah matematika terbuka dengan gaya belajar visual, auditori, dan kinestetik. Subjek penelitian ini terdiri dari tiga subjek yang masing-masing memiliki gaya belajar visual, auditori dan kinestetik. Penelitian ini merupakan penelitian diskriptif dengan pendekatan kualitatif. Adapun tahapan penelitian yang digunakan peneliti terdiri dari tiga tahap, yaitu tahap persiapan, tahap pelaksanaan, dan tahap analisis. Hasil penelitian menunjukan subjek dengan gaya belajar visual dalam memecahkan masalah matematika terbuka memenuhi tiga indikator kreativitas; yakni, kefasian, fleksibilitas dan kebaruan. Subjek dengan gaya belajar auditori dalam memecahkan masalah matematika terbuka hanya memenuhi satu indikator kreativitas; yakni kefasihan, sedangkan subjek dengan gaya belajar kinestetik dalam memecahkan masalah matematika terbuka hanya memenuhi satu indikator kreativitas; yakni kefasihan.

Abstract

Mathematics is a science that underlies the development of modern technology, has an important role in various disciplines and advance the human mind. The development in the field of information and communication technology is influenced and based on the development of Mathematics. Mathematics is a lesson that is directly related to the development of science and technology, both material and its usefulness. So Mathematics needs to be developed and upgraded including materials, teaching and learning process, environment as well as school facilities, as the special purpose of teaching Mathematics in primary school is to develop numeracy skills that are useful in everyday life. Based on the results of observations during the learning, the problem faced by students is the lack of mastery of the concept of integers so that student learning outcomes are still lacking. Teachers also still dominate learning by lecturing method so that happened is teacher centered. This makes the learners less motivated and less enthusiastic in following the lesson. For that we need to make changes in learning that is with the model of learning that creates learning to be student centered. So learning activities centered on the learners, teachers as a motivator and facilitator in it so that the atmosphere of the classroom more conducive. Teams Games Tournament (TGT) becomes one of the learning models that can be applied to change the above paradigm. This is evident in significant changes in post test results of students versus pre test results. Keywords: Teams Games Tournament (TGT), cooperative, students centered

Abstract

Since October 2017, Electronic automatic payments have been applied in all Indonesian toll roads. This payment system needes an extra system which is able to distinguish the types of motor vehicles that will enter the toll road due to the regulation itself which allow four-wheel or more vehicle to pass the toll road. This automatic system can be built by a classification algorithm, and one of the best is Support Vector Machine (SVM), in order to be able to classify non-linear separable data, SVM must be modified by giving kernel function on it. Furthermore, determining the approriate kernel for every classification problem is a fundamental step, and that’s obviously not easy, to solve that problem the researchers found a method that can make this kernel function more flexible, this method called Multi Kernel Learning (MKL). Main idea of this method is formulating some kernel function to be one kernel function. This framework is built an automatic system to classify the types of motor vehicles using Support Vector Machine modified using Multi Kernel Learning method. The experimental result shows that the system has a good average value of accuracy that is 84.60%, the average value of precision is 84.95% and also average value of recall is 84.60%.
