Abstract

Kondisi pelajar dan remaja Indonesia saat ini tengah mengalami krisis etika dan moral. Pelajar dan remaja kerap kali menjadi pelaku perbuatan asusila, melakukan tindak pidana, menyalahgunakan obat-obatan terlarang, dan berbagai bentuk pelanggaran lainnya. Hal tersebut tentu saja berdampak buruk bagi diri sendiri, keluarga, dan masyarakat. Maka diperlukan solusi yang tanggap untuk mengatasi permasalahan tersebut. Dalam bidang pendidikan, diperlukan upaya pengembangan dan perubahan kurikulum pada jenjang sekolah dasar untuk menanamkan nilai-nilai Islam dalam rangka membangun karakter siswa. Salah satunya dengan menerapkan pembelajaran matematika integrasi hadis. Kesadaran akan pentingnya penanaman nilai-nilai Islam, khususnya nilai hadis, dalam membangun karakter siswa seharusnya menjadi prioritas bagi guru dalam pembelajaran matematika.

Abstract

Efficient pedestrian pathways between faculties and key locations within the Universitas Mataram campus are a crucial aspect in supporting the academic and non-academic mobility. Optimization of pedestrian paths based on distance and connectivity efficiency between important points. This study aims to identify and optimize as well as determine the shortest pedestrian paths between faculties by applying the Kruskal algorithm, which connects all points without forming cycles based on the Minimum Spanning Tree (MST) method. There are 13 vertices representing faculties or key locations at Universitas Mataram. The distances between these faculties or places are represented as weighted edges measured in meters. A total of 15 edges were initially identified according to the algorithm’s execution. Among these, 3 edges formed cycles and had to be gradually eliminated in order to comply with Kruskal’s algorithm, resulting in the optimal solution of 12 edges for the shortest pedestrian network. The distances of these 12 edges were obtained through mapping using Google Maps. The total length of the resulting optimized pedestrian route is 2,650 meters or 2.65 kilometers. These findings can serve as a reference for policymakers at Universitas Mataram to consider in the development of network-based pedestrian infrastructure.

Abstract

Connective thinking is the process of building ideas to solve problems. This happens by connecting concepts and generalizing them to more complex mathematical problems. Connective thinking is also a stage of forming a thinking scheme that links mathematical ideas when building mathematical connections. This study aims to describe students' connective thinking abilities in building mathematical connections in solving contextual problems with a maritime theme. This study uses a descriptive qualitative approach with three student subjects selected based on different levels of ability. The main instrument is three contextual questions with the theme of ship navigation, which are analyzed through four indicators of connective thinking: cognition, formulation, inference, and reconstruction. The results indicate that high-ability students are able to go through all stages of connective thinking thoroughly and logically. Medium-ability students show an incomplete thinking process, while low-ability students experience difficulties at almost all stages. This study emphasizes the importance of contextual problems that integrates conceptual understanding and reflection to develop students' connective thinking abilities.
