SYSTEM DYNAMIC FRAMEWORK: INCREASING PRODUCTIVITY OF SUGARCANE TO SUPPORT SUSTAINABLE CULTIVATION

Abstract

Sugarcane as a raw material for producing sugar is a strategic agricultural commudity in economy and sugar industry. With the increase of population, the consumption and demand for sugar will also increase and this causes domestic sugar production to be unfulfilled. Some problem that arise in this commodity include sugarcane productivity and yields are not optimal, how to increase farmer’s income from the residue of the sugarcane harvesting. To achieve the basic need of domestic sugar, it is necessary to increase land productivity and sugarcane production in order to support the sustainable of sugarcane cultivation. The result of study show simulation scenario of intensification of the use of quality seeds, the productivity of sugarcane increased by 1.03% per year and increased sugarcane production in smallholder farmers’ gardens. PBN production increased by an average of 0.96% per year and PBS increased by an average of 1.52 per year. In addition, there is a scenario of utilizing residual crops in the form of silsage and biobriquette in year 2030. This study took a case study at PT. PTPN X Surabaya City which represents the East Java area. The harvested areas used in this study are People’s Plantation (PR), National Large Plantation (PBN) and Private Large Plantation (PBS). This study uses a key focus area of sugarcane cultivation to increase sugarcane productivity and production efficiency and support sustainable cultivation.
