Sragen Regency has enormous agricultural potential and is among one of the largest rice suppliers for the population of Central Java, Indonesia. However, since the construction of the Solo-Kertosono toll road that passes through the regency, there have been more farmlands converted for non-agricultural purposes. This study was conducted to determine the extent of land conversion into a toll road and assess the carrying capacity of agricultural land from 2011 to 2020. To identify land conversion, data from the Purwodadi Road Management Center in the regency were analyzed. Meanwhile, the mathematical formula introduced by Odum et al. was applied to the secondary data obtained from the Bureau of Statistics to calculate carrying capacity. Results show that from 2011 to 2020, rice fields were converted most extensively into toll roads, with an average of 85.28% conversion. Further, the agricultural land’s carrying capacity in affected districts fluctuated across these years due to several factors, including harvested area, rice production, productivity, and water availability for irrigation.

2011-2020年印度尼西亚斯拉根收费公路建设农地承载力

斯拉根县拥有巨大的农业潜力，是印度尼西亚中爪哇人口最大的大米供应商之一。然而，自从穿过摄政区的索罗-克托索诺收费公路修建以来，有更多的农田被转变为非农业用途。这项研究的目的是确定土地转变为收费公路的程度，并评估 2011 年至 2020 年农业用地的承载能力。为了确定土地转变，我们对摄政区普沃达迪公路管理中心的数据进行了分析。同时，Odum 等人引入的数学公式。应用从统计局获得的二手数据来计算承载能力。结果显示，2011年至2020年，稻田改建收费公路最为广泛，平均改建率为85.28%。此外，受收获面积、水稻产量、生产力和灌溉用水等多种因素影响，受影响地区的农业用地承载力多年来出现波动。
