Abstract

Cutting Stock Problem (CSP) is a problem of cutting stocks with certain cutting rules. This study used the data of rectangular stocks, which cut into triangular shape items with various order sizes. The Modified Branch and Bound Algorithm (MBBA) was used to determine the optimum cutting pattern then formulated it into the 3-Phase Matheuristic model which consisted of constructive phase, improvement phase, and compaction phase. Based on the results, it showed that the MBBA produces three optimum cutting patterns, which was used six times, eight times, and four times respectively to fulfill the consumer demand. Then the cutting patterns were formulated into the 3-Phase Matheuristic model whereas the optimum solution was the minimum trim loss for the first, second and third patterns.

Abstract

Penelitian ini bertujuan mengeksplorasi unsur budaya dan konsep matematika yang terdapat pada objek wisata religi Bayt Al-Qur'an Al-Akbar. Bayt Al-Qur'an Al-Akbar terkenal dengan Al-Qur'an raksasa yang dipahat pada lembaran kayu tembesu, menjadi salah satu destinasi wisata religi unggulan yang menggabungkan keindahan seni ukir khas Palembang dengan nilai-nilai religius. Penelitian ini menggunakan metode kualitatif dengan pendekatan etnografi dan mengadopsi prosedur penelitian Spradley yang terdiri dari enam langkah. Proses pengumpulan data dilakukan melalui observasi langsung, wawancara dengan pengurus, dokumentasi lapangan, dan studi literatur. Teknik analisis data yaitu analisis domain dan taksonomi. Hasil dari penelitian ini berupa kajian unsur budaya khas Palembang yang berupa seni ukir dengan berbagai motif di dalam Bayt Al-Quran Al-Akbar dan berbagai konsep yang termasuk didalam konsep matematika yaitu refleksi, translasi, segitiga siku-siku, persegi panjang, dan balok. Penelitian ini tidak hanya memperkaya pemahaman tentang keterkaitan antara budaya dan matematika, tetapi juga menekankan pentingnya pelestarian warisan budaya Palembang melalui seni ukir yang unik. Kata kunci: Bayt Al-Qur'an Al-Akbar, Konsep Matematika, Seni Ukir
