The problem of fl ood and drought give negative impact to water system in the catchment area. It is related to forest condition in the upstream of watershed. One cause of flooding is the use of land that does not comply with the environmental carrying capacity making the area of repage is reduced. The purpose of this research is to predict the increase of flood hydrograph due to the change of land use sub-watershed. This study used spatial and attribute data. Spatial data included digital maps of topography, digital river network map, digital map of soil types, and digital maps land use. Map of land use consisted of the existing conditions of land use, while the land use itself was based on the 2010-2030 Spatial Plan of Malang Regency. Attribute data in the form of sub-daily rainfall data in Konto watershed year 2001-2010 were collected from the Pujon and Kedungrejo station. Data was analized using SIMODAS. Result indicated that changes of land use in sub-watershed Konto in Malang Regency for 20 years (2010-2030) increase the peak of fl ood from 1014,70 m3/ second to 1101,27 m3/ second or up to 8.53 %.ABSTRAKBanjir dan kekeringan merupakan dampak dari buruknya sistem tata air sebuah DAS. Hal tersebut berkaitan dengan kondisi hutan di bagian hulu DAS. Salah satu penyebab bencana banjir yaitu pemanfaatan lahan yang tidak sesuai dengan daya dukung lingkungan, sehingga kawasan resapan air berkurang. Tujuan penelitian adalah memprediksi peningkatan hidrograf banjir karena pengaruh perubahan alih fungsi lahan di Sub DAS Konto. Penelitian ini menggunakan data spasial dan data atribut. Data spasial antara lain peta digital topografi , peta digital jaringan sungai, peta digital jenis tanah, dan peta digital tata guna lahan. Peta tata guna lahan terdiri dari tataguna lahan kondisi eksisting dan tata guna lahan berdasarkan Rencana Tata Ruang Wilayah Kabupaten Malang tahun 2010-2030. Data atribut yaitu berupa data curah hujan harian wilayah Sub DAS Konto tahun 2001-2010 dari stasiun hujan Kedungrejo dan Pujon. Data dianalisis menggunakan metode analisa spasial dan disimulasi dengan SIMODAS. Hasil penelitian menunjukkan perubahan alih fungsi lahan selama 20 tahun (2010-2030) meningkatkan debit puncak banjir dari 1014,704 m3/detik menjadi 1101,27 m3/detik atau naik sebesar 8,53 %.

Land suitability assessment was needed to plan productive and sustainable land use. The aim of this research was to de- liver an informative data about land suitability of corn using spatial analysis model. The research was conducted from July 2007 to January 2008, located in Blitar district. The land survey and analysis covered several parameters needed for suitability assessment for corn such as temperature, rainfall, soil drainage, soil texture, pH, effective depth of soil, organic- C, soil content, Cation Exchange Capacity of clay, slope, altitude, and erosion endangered. The land suitability classes were classified into four classes, those were very suitable, suitable, marginally suitable, and not suitable. The data were finally analyzed using Map Calculator in Arc View GIS Software.The results showed that there were three classes of land suitability for corn i.e. very suitable, suitable and marginally suitable which accounted for 85 %, 10 %, and 5 % of 150.96 hectare areas in Blitar. The suitable class mainly located in the northern of Blitar district, while the marginally suitable class mostly located in more than 1200 meters height above sea level covered 10, 117, and 52 hectares area of Wlingi, Gandusari, and Doko county area respectively.ABSTRAKEvaluasi kesesuaian lahan diperlukan untuk perencanaan penggunaan lahan yang produktif dan lestari. Tujuan peneli- tian adalah untuk menyajikan data dan informasi tentang evaluasi kesesuaian lahan bagi tanaman jagung menggunakan model analisa spasial. Penelitian dilaksanakan mulai bulan Juli 2007 sampai bulan Januari 2008. Lokasi penelitian dilaksanakan di Blitar, Jawa Timur. Data yang diperlukan meliputi data spasial berupa peta kontur dan peta jenis tanah skala 1:25000 serta data atribut berupa data klimatologi wilayah dan hasil pengamatan lapangan terhadap sifat fisik, morfologi dan kimia tanah. Parameter kesesuaian untuk tanaman jagung yang ditetapkan meliputi temperatur, curah hujan, kondisi drainase, tekstur, pH, kelembaban relatif, C-organik, KTK Liat, kemiringan, ketinggian tempat dan kondisi erosi. Kelas kesesuaian lahan terdiri atas kelas “sangat sesuai”, “cukup sesuai”, “sesuai marginal” dan “tidak sesuai”. Analisis spasial memanfaatkan fasilitas Map calculator dalam Software Arc View GIS.Hasil penelitian menunjukkan, di Blitar memiliki tiga kelas kesesuaian untuk tanaman jagung yaitu “sangat sesuai” 85%, “cukup sesuai” 10% dan “sesuai marginal” 5 % dari 150961 ha luas wilayah. Kelas “cukup sesuai” umumnya ter- letak di wilayah Blitar Utara dan kelas “sesuai marginal” terletak pada ketinggian di atas 1200 mdpl di sebagian kecil wilayah Kecamatan Wlingi (10 ha), Gandusari (117 ha), dan Doko (52 ha).
