Abstract

Understanding concepts is one of the goals of mathematics learning. Understanding mathematical concepts is not just knowing a concept, but being able to re-express the concepts studied in a form that is easier to understand and being able to apply them in problem solving. Students' ability to understand mathematical concepts will be formed systematically if students can construct their mathematical knowledge and connect it to contextual problems. One effort that can be made to improve students’ ability to understand mathematical concepts is to apply the Contextual Teaching and Learning approach. This research aims to determine the effect of the Contextual Teaching and Learning approach on students' ability to understand mathematical concepts. This research is a quasi-experimental research. This research was carried out at SMP Negeri 1 Pangkalan Susu. The sample selection technique used in this research is purposive sampling technique. The population of this study were all class VII students. The samples in this study were 2 classes, namely class VII-4 which was used as the experimental class and class VII-5 which was used as the control class. The results of this research show that there is an influence of the Contextual Teaching and Learning approach on students' ability to understand mathematical concepts.

Abstract

Mathematical disposition is an affective ability that is important for students to have because through this ability, students' attitudes in facing problems in mathematics will be resolved properly. One of the efforts that can be done to improve mathematical disposition is by implementing problem-based learning. By providing contextual problems in mathematics learning, it can have an impact on interest, desire and awareness in the form of a strong tendency to think and behave towards mathematics and see the usefulness of mathematics. This research aims to analyze students' mathematical disposition using problem based learning.This type of research is Quasi-experimental research.This research was implemented at SMP Negeri 1 Pangkalan Susu. The population of this research was students of class IX. The sample used was students of class IX-1 as the experimental class and IX-2 as the control class. Based on the results of t-test used in the research, the t-count value was 3,508 and the t-table value for a value of 1.67. This means that the t-count value > t-table namely 3,508 > 1,67. The results of this research state that the mathematical disposition of students who use problem-based learning is better than the mathematical disposition of students who use conventional learning.

Abstract

Abstract: Value-based community organizations, such as the Komunitas Akhwat Sholehah (KoAS) in Kisaran, face significant challenges in enforcing internal discipline. The manual and subjective process of imposing sanctions for violations often leads to perceptions of injustice, inconsistency, and inefficiency. This research aims to design and build a Decision Support System (DSS) model to assist the KoAS management in determining sanctions more objectively, transparently, and accountably. The research methodology uses a waterfall approach, including needs analysis, system design, model implementation, and testing through simulation. The core decision-making logic is implemented using the Simple Additive Weighting (SAW) method, chosen for its ability to accommodate various violation criteria simply and transparently. The result is a conceptual prototype and case simulation demonstrating the system's ability to process violation data based on weighted criteria to produce the most appropriate sanction recommendations. The main contribution is the application of a quantitative management tool (DSS/SAW) in the unique socio-technical context of a religious community, offering a technology-based internal governance model to enhance procedural justice and member trust.Keywords: Decision Support System; Governance; Procedural Justice; Simple Additive Weighting; Value-Based Community Abstrak: Organisasi komunitas berbasis nilai, seperti Komunitas Akhwat Sholehah (KoAS) di Kisaran, menghadapi tantangan signifikan dalam menegakkan disiplin internal. Proses penjatuhan sanksi terhadap pelanggaran yang dilakukan secara manual dan subjektif sering kali menimbulkan persepsi ketidakadilan, inkonsistensi, dan inefisiensi. Penelitian ini bertujuan untuk merancang dan membangun sebuah model Sistem Pendukung Keputusan (SPK) yang dapat membantu pengurus KoAS dalam menentukan sanksi secara lebih objektif, transparan, dan akuntabel. Metode penelitian yang digunakan adalah pendekatan waterfall, yang mencakup tahap analisis kebutuhan, perancangan sistem, implementasi model, dan pengujian melalui simulasi. Logika pengambilan keputusan inti dalam sistem ini diimplementasikan menggunakan metode Simple Additive Weighting (SAW), yang dipilih karena kemampuannya dalam mengakomodasi berbagai kriteria pelanggaran secara sederhana dan transparan. Hasil penelitian ini berupa sebuah prototipe konseptual dan simulasi kasus yang menunjukkan kemampuan sistem dalam memproses data pelanggaran berdasarkan kriteria yang telah dibobotkan untuk menghasilkan rekomendasi sanksi yang paling sesuai. Kontribusi utama dari penelitian ini adalah demonstrasi penerapan alat manajemen kuantitatif (SPK/SAW) dalam konteks sosio-teknis unik sebuah komunitas keagamaan, yang menawarkan sebuah model tata kelola internal berbasis teknologi untuk meningkatkan keadilan prosedural dan kepercayaan anggota.Kata kunci: Keadilan Prosedural; Komunitas Berbasis Nilai; Simple Additive Weighting; Sistem Pendukung Keputusan; Tata Kelola

Abstract

Communication skills are one of the important aspects in mathematics education, which aims to make students more enthusiastic, broad-minded, and focused on a problem. Efforts to improve students' mathematical communication skills include applying appropriate learning models. This study aims to examine the effectiveness of the Numbered Heads Together (NHT) learning model on students' mathematical communication skills. This study adopted a quantitative method through a quasi-experimental design. The population studied consisted of all seventh-grade students at SMP Swasta Dharma Patra Pkl. Susu. Two classes were selected as samples: class VII-1 with 30 students as the experimental class and class VII-2 with 30 students as the control class. The research tool used was an essay test on the topic of quadrilaterals measured by providing pretest and posttest questions. The data analysis process was carried out using the T-test in the SPSS 22 application. The results of the study showed a difference in mathematical communication skills between students who received learning through the Numbered Heads Together (NHT) model and students who received conventional teaching. Based on the results of the T-test at a significance level of 5% with degrees of freedom (dk) = 58, the t-value obtained was 2.589, which exceeds the t-table value of 2.0017. This means that Ho is rejected and Ha is accepted. Therefore, it can be concluded that students taught with the Numbered Heads Together (NHT) learning model have better mathematical communication skills than students taught through conventional learning.
