Abstract

Jalan Khatib Sulaiman merupakan kawasan komersial dan pusat bisnis di kota Padang yang terdiri dari dua jalur dan masing-masing terbagi menjadi tiga lajur. Selain jalan yang lebar, Jalan Khatib Sulaiman juga relatif lurus dan panjang sehingga menyebabkan pengemudi dapat meningkatkan laju kendaraannya di atas batas yang diizinkan. Salah satu upaya yang dapat dilakukan untuk mengurangi kecepatan kendaraan melebihi batas yang diizinkan yaitu dengan memasang pita penggaduh. Pengambilan data dilakukan dengan merekam kondisi lalu lintas di jalan tersebut menggunakan handycam setelah itu mencatat waktu tempuh sesuai titik yang sudah ditentukan untuk mendapatkan kecepatan kendaraan. Tujuan penelitian ini untuk melihat perbedaan kecepatan kendaraan sebelum dan sesudah melewati pita penggaduh serta efektivitas penggunaan pita penggaduh terhadap kecepatan kendaraan di jalan tersebut. Analisis data mengunakan Analisis Non Linier, uji Koefisien Determinasi, dan Uji T. Hasil penelitian menunjukkan bahwa dimensi pita penggaduh yang terpasang di Jalan Khatib Sulaiman belum sesuai dengan standar ketentuan dari Permenhub RI No. 14 Tahun 2021. Kecepatan rata-rata kendaraan sebelum dan sesudah melewati pita penggaduh tidak mengalami penurunan yang signifikan.

Abstract

Background: Vocational schools in border areas face systemic challenges such as limited infrastructure and poor curriculum-context alignment, hindering effective mathematics instruction and student engagement.Aims: This study investigates how mathematics learning is organized and implemented in a vocational high school situated in the Entikong border area of West Borneo, Indonesia. The research seeks to identify instructional patterns, contextual challenges, and adaptive strategies used by educators under constrained conditions.Method: Using a qualitative case study design, data were gathered through direct classroom observation, semi-structured interviews with teachers and school leaders, and review of official teaching documents. Thematic analysis and data triangulation were employed to ensure rigor and credibility.Results: The analysis highlights a continued reliance on teacher-centered instruction, minimal use of contextual or vocationally integrated methods, and limited student engagement. Assessment practices predominantly measure cognitive outcomes, lacking elements that support student reflection or vocational competencies. Curriculum delivery is often disrupted by time limitations and infrastructural shortfalls.Conclusion: Improving mathematics instruction in border-based vocational schools necessitates flexible teaching models tailored to the local context. Strengthening professional development, embedding authentic assessments, and enhancing school-community collaboration are crucial steps toward addressing educational disparities in underserved regions.
