Abstract

Construction of a hull generally requires a number of plates and profile material. Early indications for shipbuilding indicate that installed material is between 85% and 90% and the waste material is between 10% and 15%. Secondary data retrieval in the form of plans for cutting plate material and aluminum profiles from the AutoCAD application which are then reprocessed through the FastCAM application to obtain results in the form of identification of installed material area and waste material. Based on variations in ship length and material area results, a scatter plot process was carried out through the Excel application to obtain results in the form of trend line functions with an R-square determination coefficient of more than 0.9 and the results of the calculation of the intersection between the function of installed material and the waste material and the waste material function with the x-axis uses the balance method. The final result showed that the linear function gives an indication of the effectiveness of the material located in the range of 6.5 to 20 meters in length of the ship and polynomial function of order 2 in the range of 6.5 to 23 meters in length, while the waste material area in the two functions in the maximum range of 10% to 14%.
