Abstract

The rainbow connection number is a topic in graph theory that studies the minimum number of colors required on the edges of a graph such that every pair of vertices is connected by a path with distinct edge colors. This study aims to determine the rainbow connection number of snail graphs and jellyfish graphs. The method used is a theoretical approach through structural analysis of graphs and the construction of minimum edge-coloring patterns that satisfy the rainbow connected property. The results show that the rainbow connection number of the snail graph Sl_n is rc(Sl_n)=4 for n=1,2, rc(Sl_n)=5 for n=3,4, and rc(Sl_n)=6 for n≥5. Meanwhile, for the jellyfish graph J_n, it is obtained that rc(J_n)=2n+1. These results indicate that the structure of a graph significantly influences the rainbow connection number. Although the diameter of the jellyfish graph is constant, the structural complexity causes the rainbow connection number to increase linearly with respect to n. This study is expected to contribute to the development of research on rainbow connection in special graphs.

Abstract

The low understanding of mathematical concepts and students' learning interest remain major challenges in mathematics education at the Islamic Junior High School (MTs) level. This study aimed to analyze the effect of the Problem Based Learning (PBL) model on students' understanding of mathematical concepts and learning interest. This research employed a quasi-experimental design with a static group comparison: Randomized Control-Group Only Design. The population comprised 37 eighth-grade students distributed across two classes. A total sampling technique was utilized due to the limited population size. The experimental and control classes were determined through a lottery method, following tests for normality, homogeneity, and equality of means based on daily test scores. Data were collected using an essay test and a questionnaire, and subsequently analyzed using a t-test. The findings revealed that the average scores for concept understanding and learning interest in the experimental class were 68.67 and 78.20, respectively. Meanwhile, the control class achieved average scores of 54.59 and 73.36, respectively. The t-test for concept understanding yielded , and the learning interest questionnaire yielded . These results indicate that Problem Based Learning has a significant effect on students' understanding of mathematical concepts and learning interest.

Abstract

In the process of trading, the supply of goods is needed, furthemore in the competition of trading. Therefore, the supply of the the goods are needed, in order to maintain consumer trust toward the sales unit, which assumes the the availability of the goods. This study will analyze the calculation of the demand and the selling of goods in UD.Jasa Tani that impact to supply of the goods in that trading business. Thus, to solve the problems, the researcher tries to simulate the calculations on that business trade with probabilistic and deterministic comparison method in order to give solution to the problems that occur in that business trade. Dalam proses jual beli ketersediaan stok barang sangat diperlukan, apalagi dengan adanya persaingan dalam proses jual beli. Oleh karena itu ketersediaan barang sangat diperlukan, guna menjaga kepercayaan konsumen terhadap suatu unit penjualan, yang menganggap di tempat tersebut ketersediaan barangnya selalu terjaga. Penelitian ini akan menganalisis perhitungan terhadap laju penjualan dan permintaan barang yang terjadi pada UD. Jasa Tani yang berakibat pada ketersediaan stok barang pada usaha dagang tersebut. Maka untuk menyelesaikan masalah yang terjadi, peneliti mencoba untuk mensimulasikan perhitungan penjualan pada usaha dagang tersebut dengan metode perbandingan probabilistik dan deterministik sehingga diharapkan ini, bisa mempermudah proses analisa, sehingga bisa memberikan solusi untuk permasalahan yang terjadi di usaha dagang tersebut.

Abstract

This study aims to determine the effect of the Realistic Mathematics Education approach on the mathematical representation ability of eighth-grade students at SMPN 1 Banuhampu. The study used a pre-experimental method with a Static Group Comparison Design. The study population was all eighth-grade students consisting of nine classes. The sample was selected through a random sampling technique after conducting normality tests, homogeneity of variance, and equality of means, resulting in class VIII.7 as the experimental class and class VIII.9 as the control class. The experimental class was given learning using the Realistic Mathematics Education approach, while the control class used conventional learning. The research instrument was a mathematical representation ability test given after the treatment. Data were analyzed using the t-test after fulfilling the prerequisite tests for normality and homogeneity. The results showed that the average mathematical representation ability of students in the experimental class was higher than the control class. The results of the t-test and the P-value obtained showed that the difference was statistically significant. Thus, it can be concluded that the Realistic Mathematics Education approach has a significant effect on improving the mathematical representation ability of eighth-grade students at SMPN 1 Banuhampu

Abstract

Penelitian ini dilatarbelakangi oleh rendahnya pemahaman konsep matematika siswa kelas VII MTs.S Terpadu Guguak Randah. Berdasarkan hasil observasi dan wawancara, ditemukan bahwa siswa mengalami kesulitan dalam menyelesaikan soal dengan bentuk yang berbeda meskipun memiliki konsep yang sama. Proses pembelajaran juga masih berpusat pada guru sehingga siswa cenderung pasif. Selain itu, sebagian besar hasil belajar siswa masih berada di bawah Kriteria Ketuntasan Minimal (KKM). Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran kooperatif tipe Student Teams Achievement Division (STAD) terhadap pemahaman konsep matematika siswa. Jenis penelitian yang digunakan adalah eksperimen dengan rancangan The Static Group Comparison Design. Populasi penelitian ini adalah seluruh siswa kelas VII MTs.S Terpadu Guguak Randah Tahun Pelajaran 2019/2020, dengan sampel penelitian yaitu kelas VII.1 sebagai kelas eksperimen dan kelas VII.2 sebagai kelas kontrol. Data diperoleh melalui tes kemampuan pemahaman konsep matematika dan dianalisis menggunakan uji-t. Hasil analisis menunjukkan bahwa nilai t_hitung=2,36 lebih besar dari t_tabel=1,68dengan nilai p-value = 0,022 < 0,05, sehingga H₀ ditolak. Dengan demikian, terdapat pengaruh yang signifikan antara penerapan model pembelajaran kooperatif tipe STAD terhadap pemahaman konsep matematika siswa kelas VII MTs.S Terpadu Guguak Randah.
