Crop production rate relies on rainfall over Rejang Lebong district. Data showed a discrepancy between increased crop production and rainfall in Rejang Lebong District. However, the spatiotemporal distribution of the crop variable's dependencies remains unclear. This study analyses the relationship between rainfall and crop production rate in the Rejang Lebong district based on the performance of the machine learning method. In addition, this research also performed regression analysis to carry out rainfall clusters and crop production. This order provides information in the form of cluster results to determine how much the rainfall variable influences the crop production rate  in each cluster. Harnessing the Elbow, CLARANS, Simple Linear Regression, and Silhouette Coefficient methods, this study used 231 rainfall data sourced from the Bengkulu BMKG and 110 data for plant production obtained from BPS Bengkulu Province from 2000-2022. This research found that the optimal clusters were 3 clusters. C1 contains 106 data with the largest regression value for chili = 0.127, C2 contains 15 data with the largest regression value for mustard greens = 0.135, and C3 contains 110 data with the largest regression value for cabbage = 0.408, eggplant = 0.197, and carrots = 0.201. Furthermore, this research also found that the biggest correlation of crops with highly significant improvement would be cabbage commodity (Y=0.4114X+0.2013) and chili plantation with high RSME (0.9897).

KKN Kebangsaan merupakan kegiatan tahunan yang disepakati okeh perguruan-perguruan tinggi se-Indonesia dalam rangka memberikan pelatihan dan pembelajaran bagi mahasiswanya. KKN sebagai bagian dari kegiatan ekstrakurikuler bagi mahasiswa program S1 dilaksanakan dalam bentuk pengintegrasian antara kegiatan-kegiatan Pendidikan dan Pengajaran, Penelitian serta Pengabdian kepada Masyarakat secara interdisipliner.

Sesuai dengan kondisi geografis serta kemasyarakatan di Kabupaten Tanjung Jabung Timur, KKN Kebangsaan tahun 2021 di Provinsi Jambi mengusung tema, “Membangkitkan Nilai-Nilai Kebangsaan dan Kebersamaan Melalui Pemberdayaan Masyarakat Berbasis Agroindustry”. Beberapa program kerja tersebut diantaranya pembuatan taman wisata mangrove, pembuatan permen nanas, pembuatan dodol dari bonggol pisang, Pembuatan rumah pembibitan pisang unggul, dan pengelolaan sampah anorganik di TPA menjadi kursi melalui metode ecobcrick. Hasilnya seluruh rancangan program kerja tersebut berhasil dilaksanakan selama masa KKN mahasiswa. AGROINDUSTRY BASED COMMUNITY EMPOWERMENT IN TANJUNG JABUNG TIMUR REGENCY THROUGH KKN KEBANGSAAN IN 2021, UNIVERSITY OF BENGKULU. KKN Nationality is an annual activity agreed by universities throughout Indonesia in order to provide training and learning for their students. The KKN as part of extracurricular activities for undergraduate students is carried out in the form of integration between Education, Teaching, Research and Community Service activities in an interdisciplinary manner. The 2021 KKN Nationality held in Tanjung Jabung Timur Regency, Jambi Province. The Tanjung Jabung Timur area has the potential to be developed as an agricultural, plantation and tourism area. In accordance with the geographical and social conditions in Tanjung Jabung Timur Regency, the 2021 KKN Nationality Program in Jambi Province carries the theme, "Generating National Values and Togetherness through Agroindustry-Based Community Empowerment". Some of these work programs include the creation of a mangrove tourism park, the manufacture of pineapple candy, the manufacture of lunkhead from banana weeds, the manufacture of superior banana nurseries, and the management of inorganic waste in the landfill into chairs through the ecobcrick method. As a result, all of the work program designs were successfully implemented during the student KKN period.
