Abstract

Pemahaman konsep dapat ditingkatkan dengan cara siswa mengerjakan secara individual bukan berkelompok. Dalam Teori APOS terdapat tahap aksi, proses, objek, dan skema yang memungkinkan siswa dapat membantu siswa memahami konsep. Selain pemahamn konsep, siswa juga belum mampu memecahan masalah yang berkaitan dengan sehari-hari sehingga perlu adanya pendekatan Etnomatematika yang digunakan untuk menyampaikan materi di kelas. Tujuan penelitian ini adalah untuk mengetahui keefektifan penggunaan teori APOS dengan pendekatan etnomatematika dalam meningkatkan pemahaman konsep dalam belajar matematika. Jenis penelitian ini adalah kuasi eksperimen. Desain penelitian adalah Nonequivalent Control Group Design. Teknik Pengumpulan data yaitu Observasi, Tes (Pre-Test dan Post-Test). Intrumen penelitian meliputi lembar obsevasi dan soal pemahaman konsep matematika. Prosedur penelitian meliputi: persiapan, pelaksanaan, pengolahan data dan hasil. Berdasarkan hasil uji N-gain, penggunaan teori APOS dalam pendekatan etnomatematika terbukti efektif untuk meningkatkan pemahaman konsep siswa sebesar 0,75 jika dibandingkan dengan peningkatan kemampuan pemahaman konsep siswa yang menggunakan model pembelajaran STAD (Student Teams Achievement Division) yang mencapai 0,62. Faktor yang mempengaruhi keefektifan ini yaitu tahapan APOS, Gaya Belajar Siswa, Latihan rutin dan soal Etnomatematika yang diberikan pada penelitian ini. Kata Kunci : APOS Theory , Ethnomathematics, Understanding Concepts

Abstract

This study aims to measure the distance between Islamic boarding schools in East Oku, using the Dijkstra Algorithm method to make it easier to determine the shortest route from the point of the Nurul Huda Sukaraja Islamic Boarding School to the Subulussalam Sriwangi Islamic Boarding School. In previous research, namely determining the shortest route when distributing from vegetable gardens to warehouses between toll and non-toll routes to minimize costs. In graph theory, the Dijkstra algorithm efficiently calculates the shortest path between any pair of nodes in a weighted graph, both positive and negative. This algorithm works with the principle of dynamic programming and can overcome graphs with a negative weight as long as there are no negative cycles. In its implementation, the Dijkstra algorithm iteratively updates the shortest distance between nodes by directly comparing paths with paths passing through other nodes. The advantage of this algorithm lies in its simplicity and ability to calculate the shortest distance between all pairs of nodes in a single process. The study results show that the Dijkstra Algorithm can show the fastest and most efficient alternative routes compared to conventional routes. Calculations using the Dijkstra Algorithm method produce the shortest trajectory starting from point 1-4-5 with a distance of 48 km, the most optimal route between the location and destination points.
