AbstractThe 2014 eruption of Kelud Volcano has brought various effects on the surrounding agriculture. Aside from negative impact, it affected the potentials of agricultural land positively. This research analyzed the optimization of eruption-affected land using several steps. The first step was land suitability analysis with multicriteria assessment and Geographic Information System (GIS) technology. In addition to the physical analysis, Focus Group Discussion (FGD) was performed in the second step to identify the community’s perception of the eruption impact. The research produced land suitability maps consisting of the following classification: S1 (64.74%), S2 (31.51%), and S3 (3.75%). The maps revealed that the majority of the land in Kelud Volcano had the potentials for agricultural development. These findings were supported by the perception of the local community, which argued that they could significantly benefit from the positive impact of the eruption. Abstrak Erupsi gunungapi Kelud pada tahun 2014 membawa dampak yang beragam terhadap kondisi pertanian di sekitarnya. Selain dampak negatif, erupsi gunungapi Kelud membawa dampak positif khususnya pada potensi lahan terdampak yang perlu dioptimalkan. Melalui penelitian ini, kajian optimalisasi potensi lahan terdampak erupsi dilakukan dengan beberapa tahapan. Tahap pertama berupa analisis kesesuaian lahan melalui penilaian multikriteria dan teknologi Sistem Informasi geografis (SIG). Selain kajian fisik, kegiatan Focus Group Discussion (FGD) merupakan tahapan kedua yang dilakukan untuk mengetahui bagaimana persepsi masyarakat terkait dengan dampak erupsi Gunungapi Kelud. Hasil penelitian menghasilkan peta kesesuaian dengan kelas kesesuaian S1 (64,74%), S2 (31,51%), S3 (3,75%). Berdasarkan hasil pemetaan ini, sebagian besar wilayah Gunungapi Kelud berpotensi untuk pengembangan pertanian. Hal ini didukung dengan persepsi masyarakat kawasan Gunungapi Kelud yang berpendapat bahwa dampak positif erupsi dirasakan secara signifikan.
