Get PDFPesawaran Regency is one of the largest cocoa-producing areas in Lampung Province. Pesawaran Regency has a cocoa area of 27,411 ha with total production in 2021 reaching 30 thousand tons, with an average production per hectare of approximately 1 ton of dry cocoa beans. This is considered to be quite low considering the potential for cocoa production, which is up to 2 tons per hectare of dry beans. There are many aspects that lead to low cocoa production in Pesawaran Regency [1]. In connection with the efforts to rejuvenate the cocoa plant in Pesawaran Regency with the use of land, vegetation and the area of the area, it is hoped that there will be an appropriate use of cocoa cropping patterns. Thus the analysis of land suitability and climate is of course very important for efforts to make efficient use of land for cocoa commodities. Suitable land and climatic conditions will produce good cropping patterns and optimal results. This study uses a survey method by taking several sample points of community gardens that will be replanted in the cocoa revitalization program. Sampling points were taken based on the condition of the land and the condition of land cover or vegetation in the pesawaran cocoa area. Each village is classified into 3 areas. Based on the results and discussions that have been obtained, it can be concluded that the experimental plots of the Sungailangka and Wiyono Village cocoa farms each produced a micro-climate that varied with each element meeting the appropriate cocoa growing requirements
