Agricultural Land Monitoring of Land Subsidence Area Using Spatio-Temporal Approach in East Java Indonesia 2018-2022

Java Island is the center of economy and government so that infrastructure and economic development are evenly distributed and the accessibility is high, including in East Java. As a result, East Java has become a migration destination which causes its population to continue to increase from 2018 to 2022 as it increases the chances of land conversion. As a province with high rice production, this is a challenge for East Java to maintain its rice production. A calculation was carried out to determine the carrying capacity class of East Java agricultural land in 2018 -2022 using a combined method of Odum, Christaller, Howard, and Issard. The analytical method used in this study is quantitative descriptive analysis with a spatial-temporal approach. The results showed that the carrying capacity class of East Java’s agricultural land from 2018 to 2022 continued to decline. Since 2021 there are no more areas in class I of the agricultural land carrying capacity. The lowest carrying capacity of agricultural land is in Surabaya Municipality, while the highest is Ngawi Regencies. East Java experienced a decrease in the carrying capacity of agricultural land from class II in 2018 to class III from 2019 to 2022
