Abstract

Mathematics is one material that most students do not like. In addition to being less attractive, elementary school students also tend to have grades among their peers. This shows the lack of attention applied in learning mathematics. This study aimed to analyze the relationship and influence of cooperative characters with student responses by using traditional games in learning. This type of research uses quantitative methods with the type of comparative research. This research was conducted by distributing questionnaires. The data analysis technique used is random sampling. The research subjects in this study were 120 students. The results obtained are that the cooperative character in the traditional game of Congklak is superior, which is in a very good percentage (60%). The student's response to the traditional game of congklak was very good (55%). The results of the correlation test of the cooperative character of students in traditional games, namely, there is a relationship between the character of cooperation with students' responses to the traditional game of congklak in mathematics. It can be said that there is a relationship and influence of the character of cooperation with student responses.

Abstract

Salah satu contoh masalah dalam graf adalah pencarian pohon merentang. Terdapat dua kasus yang pada umumnya dibahas dalam pencarian pohon merentang, yaitu pohon merentang maksimum dan pohon merentang minimum. Ada beberapa algoritma yang dapat digunakan untuk mencari pohon merentang minimum dari sebuah graf berbobot atau dikenal dengan istilah pencarian Minimum Spanning Tree (MST). Pada penelitian ini dilakukan pencarian Minimum Spanning Tree pada jaringan pipa air PDAM pada perumahan mendalo asri, menggunakan Algoritma Prim. Pencarian dilakukan secara manual dan menggunakan software TORA. Pengambilan data dilakukan di kantor PDAM Tirta Muaro Jambi, Provinsi Jambi. Dari data yang diperoleh dapat disusun gambar jaringan dalam bentuk graf terhubung dan tak berarah serta memiliki bobot. Dari gambar jaringan tersebut selanjutnya dilakukan pencarian Minimum Spanning Tree. Pada penelitian ini, dapat diketahui bahwa pencarian Minimum Spanning Tree menggunakan algoritma prim baik secara manual maupun dengan bantuan software TORA, menunjukkan pemilihan sisi pada iterasi yang sama dan menghasilkan struktur MST dengan jumlah bobot yang sama juga yaitu sebesar 5.876 meter. Dibandingkan dengan graf awal yang berbobot 7.898 meter, maka hasil dari Minimum Spanning Tree menunjukkan selisih bobot pipa yang cukup signifikan yaitu sebesar 2.022 meter.

Abstract

Dalam pelajaran matematika terdapat banyak konsep yang mengharuskan siswa untuk menggunakan penalaran proporsionalnya. Penalaran proporsional dapat menjadi petunjuk tinggi rendahnya penguasaan matematika siswa pada pokok bahasan yang melibatkan masalah perbandingan. Tujuan penelitian ini adalah menganalisis penalaran proporsional siswa dengan gaya belajar auditori di kelas VII SMP Negeri 6 Kota Jambi dalam menyelesaikan soal perbandingan sub materi perbandingan senilai dan mengetahui kesalahan-kesalahan siswa dengan gaya belajar auditori dalam menyelesaikan soal tes penalaran proporsional. Hasil penelitian menunjukkan bahwa siswa dengan gaya belajar auditori belum menggunakan penalaran proporsionalnya dalam menyelesaikan soal. Siswa dengan gaya belajar auditori belum memenuhi ketiga indikator penalaran proporsional. Dari hasil penelitian dapat dilihat bahwa pada indikator pertama enam siswa dengan gaya belajar auditori atau 100% siswa dengan gaya belajar auditori dominan bisa menemukan kuantitas yang ingin dibandingkan. Pada indikator kedua dari enam siswa dengan gaya belajar auditori lima diantaranya menggunakan kuantitas tersebut hanya untuk mencari nilai satuan saja, bukan untuk menemukan intensif hubungan atau rasio dari dua kuantitas dimana anak menggunakan proporsi-proporsi dari kuantitas yang ada, hanya satu orang atau 16,6% dari siswa dengan gaya belajar auditori yang menggunakan semua kuantitas untuk menemukan intensif hubungan. Pada indikator ketiga enam anak auditori dominan tidak menggunakan perkalian silang untuk menyelesaikan soal yang melekat pada situasi perbandingan hanya satu orang atau 16,6% siswa dengan gaya belajar auditori yang menggunakan perkalian silang pada situasi perbandingan. Dari penelitian yang dilakukan anak auditori memiliki kesalahan berupa kesalahan konseptual dan kesalahan prosedural. Kata Kunci : penalaran proporsional siswa, siswa auditori, penyelesaikan soal matematika.
