The development of a certified seed plant (CSP) to increase the production of sugarcane cultivation is one of the primary efforts of the Indonesian government. The purpose of this study was to evaluate the impact of CSP adoption on the productivity and efficiency of smallholder sugarcane farmers in Indonesia. This study used data from the 2014 Indonesian Plantation Farm Household Survey consisting of 3849 farmers. We used propensity score matching to evaluate the impact of CSP adoption on the productivity and technical efficiency of sugarcane farming. We found that the adoption of CSPs increases the productivity of sugarcane farming. The average yield of the farmers who adopt CSPs is 88.24 tons/ha while the average yield of those who do not adopt CSPs is 82.94 tons/ha. Additionally, the adoption of CSPs increases the technical efficiency of sugarcane farming. The average efficiency of the farmers who adopt CSPs is 78.31%, while the non-adopting farmers have a technical efficiency of 76.44%. These results suggest that the current policy regarding CSP adoption has been on the right track. However, the government should encourage farmers to exercise good farming practices since the technical efficiency is low. Additionally, since the current rate of adoption is only 18.13%, the government should prioritize policies encouraging the adoption of CSPs.

认证种子植物的采用对印度尼西亚小农户甘蔗农民的生产力和效率的影响

发展认证种子植物（CSP）以增加甘蔗种植的产量是印度尼西亚政府的主要努力之一。这项研究的目的是评估采用CSP对印度尼西亚小农甘蔗种植者的生产率和效率的影响。这项研究使用了2014年印度尼西亚人工林农场家庭调查的数据，该调查由3849位农民组成。我们使用倾向得分匹配来评估采用CSP对甘蔗种植的生产力和技术效率的影响。我们发现采用CSP可以提高甘蔗种植的生产率。采用CSP的农民的平均产量为88.24吨/公顷，而不采用CSP的农民的平均产量为82.94吨/公顷。另外，采用CSP可以提高甘蔗种植的技术效率。采用CSP的农民的平均效率为78.31％，而未采用CSP的农民的技术效率为76.44％。这些结果表明，当前采用CSP的政策是正确的。但是，由于技术效率低下，政府应鼓励农民采取良好的耕作方式。此外，由于目前的采用率仅为18.13％，因此政府应优先考虑鼓励采用CSP的政策。由于技术效率低下，政府应鼓励农民采取良好的耕作方式。此外，由于目前的采用率仅为18.13％，因此政府应优先考虑鼓励采用CSP的政策。由于技术效率低下，政府应鼓励农民采取良好的耕作方式。此外，由于目前的采用率仅为18.13％，因此政府应优先考虑鼓励采用CSP的政策。
