Kerajinan kain tenun ATBM memerlukan tahap pemotongan dalam proses produksinya. Pemotongan bahan baku kain umumnya hanya bertujuan memenuhi permintaan, tanpa memperhatikan sisa pemotongan. Hal ini dapat berakibat pada meningkatnya biaya produksi, sehingga pemotongan bahan baku kain perlu direncanakan untuk mendapatkan pola pemotongan optimal yang memenuhi permintaan dan meminimumkan sisa pemotongan (trim loss). Masalah ini dikenal sebagai cutting stock problem. Pada penelitian ini, penyelesaian cutting stock problem satu dimensi dilakukan melalui pendekatan model arc flow. Hasil yang diperoleh untuk meminimumkan sisa pemotongan didapatkan dengan memotong 34 bahan baku kain berukuran 25 m, dengan kombinasi tiga pola pemotongan optimal, yaitu pola 1 sebanyak 13 buah, pola 2 sebanyak 3 buah, dan pola 3 sebanyak 18 buah. Berdasarkan ketiga pola optimal tersebut, didapatkan sisa pemotongan minimum sebesar 0 m. ATBM handwoven crafts require the cutting process in their production lines. The cutting process is usually aimed to satisfy the demand without considering the trim loss. This problem can lead to the increasing of production costs. The alternative way to overcome this problem is by finding a cutting plan that would satisfy the demand and minimize the trim loss. This problem is widely known as the cutting stock problem. This research solves the one-dimensional cutting stock problem using an arc flow formulation. The result that minimizes the trim loss can be obtained by cutting 34 pieces of twenty five-meter fabrics, with the optimal combination consisting of the first pattern as many as 13, the second pattern as many as 3, and the third pattern as many as 18. As a result, this optimal combination takes zero trim loss.
