Brown planthopper (Nilaparvata lugens Stal.) is one of rice plants' pests that attack from the nursery to the harvest stage. Controls carried out by farmers generally use synthetic insecticides. Reducing the impact caused by synthetic insecticides, an alternative that can be used to controlling the brown planthopper is by using botanical insecticide tuba root. Tuba root plants have been widely reported to control pests and contain the active ingredient rotenone. Rotenone works as a stomach poison and selective. This study aims to examine the ability of tuba root plant parts extracts (leaves, branches, and roots) with organic solvents to control brown planthopper pests in rice plants. The study was conducted in February-April 2019 at the Plant Pest Laboratory, Faculty of Agriculture, University of Riau. The study was conducted experimentally using a Completely Randomized Design (CRD) with three treatments and six replications to obtain 18 experimental units. The tuba root plant trial test consists of 3 levels: root extract, branch extract, and leaf extract with organic solvents. The parameters observed were the time of death of brown planthopper (hour), lethal meantime (LT50) (hour), daily mortality (%), and total mortality (%). The results showed that the application of root extract caused an initial death of 2.33 hours after application, LT50 17.33 hours after application with a total mortality rate of 100%. Application of botanical insecticide tuba root is effective for controlling brown planthopper pests in rice plants because it causes the death of brown planthopper above 80%.

Climate change has a negative impact on the agricultural sector in Yogyakarta, Indonesia, especially the farms, which are highly vulnerable to climate-related disasters such as flood and drought, as well as pest attacks that may cause production failure. This study aims to build a model of climate change adaptability for farmers in Yogyakarta. This study is qualitative in nature by using data from Focus Group Discussion (FGD) involving the community members at the district level. Each of the 12 districts in the area sent two representations of farmer assistants. Data reliability and validity was ensured through triangulation; then examined by using content analysis. The adaptability models for climate change are presented in two scenarios; the first is caused by drought/flooding and the second is by pest attack. From the data, it could be concluded that farmers’ mitigations consist of structural and non-structural approach. The construction of dam as part of the water management is the main structural mitigation undertaking. Learning the weather, the climate and other disaster causes were the main non-structural mitigation undertaking. Moreover, learning was not only from classes and practices, but also via technology transfer using free website sources to enrich farmers’ knowledge in handling pest attack.
