Climate change can affect the diversity and growth of tropical plants, one of which is Sambiloto. Sambiloto is a wild plant with medicinal potential that is experiencing scarcity due to climate change in Indonesia. This study aims to identify the agroecological suitability of Sambiloto. The research was carried out using the survey method. The survey method includes the study of description and identification and the distribution pattern of sambiloto. The results showed that Sambiloto could grow at an altitude of 180 – 861 meters above sea level with a temperature of 20.32 °C -26.93 °C, relative humidity 78% - 87%, rainfall 2053.2-3555.6 mm/year. Sambiloto can grow on soils with moderate N, low P, low Mg, very low to low Ca, low to moderate organic C, while the pH is slightly acidic to acidic. The distribution pattern of sambiloto in the middle and lowlands is clustered, while in the highlands, it is uniform. The highest andrographolide content was obtained from sambiloto in the middle plains (2.27%), while in the lowlands (1.37%) and highlands (0.89%). Sambiloto is more commonly found in the middle lands (RD 76.87%, RF 10%, RK 27.75%, IVI 114.62%) than in the lowlands (RD 59.50%, RF 9.09%, RK 31.41%, IVI 99.98%), and highlands. (RD 42.20%, RF 3.88%, RK 11.62%, and IVI 78.21%).
