Pengembangan Model Estimasi Produksi Gula Tebu Berdasarkan Distribusi Kadar Gula Segmen Batang

Abstract

Sugarcane production is greatly influenced by the sugar content in sugarcane stalks that are not evenly distributed in each stem segments. Variations in sugar content between the top, middle, and bottom segmnts have the potential to affect the accuracy of sugar production estimates. Therefore, this study aims to develop a model for estimating sugarcane production based on the distribution of sugar content in the stem segment. This research used a quantitative approach through two stages. The first stage was carried out by taking data directly on sugarcane stalks to obtain the relationship between the sugar content of the stem segment and the whole sugar content using multiple linear regression. The second stage was carried out through pure sugar dissolution experiments with mass variations to obtain the relationship between whole sugar content and sugar production estimates using simple linear regression. The two models are then combined through a substitution process to form a model of sugar production estimation. The results showed that each segment of the stem had a different contribution to whole sugar levels, with the bottom segment having the greatest contribution. The resulting model shows a positive linear relationship between whole sugar content and sugar production, with an accuracy rate of 86,9%. These results show that the stem segment distribution-based approach is more representative than the average approach in the estimation of cane sugar production. The developed model can be used as an initial estimation tool, although it still has limitations because it uses a linear approach and has not taken into account external factors.
