Abstract

The increasing demand for land has resulted in the reduction of potential agricultural land. Land suitability evaluation is an effort that can be made to determine the capacity of land for a particular commodity or crop development through various standardized land use requirements. East Java as a region that supplies vegetable commodities on a national scale still requires various efforts to optimize land use. This research aimed to identify areas that have potential land for cultivating potatoes. This identification was carried out using remote sensing which was then cross-checked with actual potato production data from each region in East Java Province. Based on data processing that had been carried out, in general, East Java is dominated by areas with land suitability classes in class N (not suitable), S3 (marginally suitable), and S2 (quite suitable). Lowland areas are dominated by class N (not suitable) because the land characteristics do not meet the requirements for growing potato plants. Meanwhile, the S3 and S2 classes are spread across the highlands with land units that meet the requirements and characteristics of land for cultivating potatoes. Efforts for classification, conservation, and so on become a unity to optimize and increase potato production in each region.

Abstract

Sektor pertanian merupakan sektor dengan kerentanan tinggi terhadap perubahan iklim, sehingga diperlukan informasi iklim untuk merencanakan langkah strategis dalam penentuan masa tanam. Pemetaan zona agroklimat oldeman menjadi salah satu cara yang dapat digunakan untuk membantu menentukan masa tanam pada suatu wilayah. Penelitian ini bertujuan melakukan pemetaan zona agroklimat di Provinsi Bali. Data yang digunakan adalah data curah hujan Climate Hazard Groups Infrared Precipitation with Station (CHIRPS) tahun 1983-2023. Data CHIRPS diolah menggunakan metode interpolasi Inverse Distance Weighted dan overlay melalui sistem informasi geografi. Hasil penelitian menunjukkan bahwa di Provinsi Bali terdapat tujuh zona agroklimat, yakni C2 (1,61%), C3 (0,0%), D2 (82,19%), D3 (0,74%), D4 (0,04%), E2 (15,38%) dan E3 (0,04%). Zona C2 dan C3 cocok untuk ditanami padi sekali dan palawija dua kali  dalam setahun, pada penanaman palawija kedua harus hati-hati jangan masuk bulan kering. Zona D2 dan D3 hanya mungkin ditanami satu kali padi atau palawija dalam setahun, namun kondisi tersebut juga bergantung pada kondisi irigasi. Zona E2 dan E3 umumnya terlalu kering, mungkin hanya dapat ditanami satu kali palawija dan sangat bergantung pada curah hujan. Berdasarkan hasil pemetaan zona agroklimat, diketahui bahwa telah terjadi perubahan sebaran zona agroklimat dari pemetaan awal yang dilakukan oleh Oldeman. Zona B1, B2, dan E4 tidak ditemukan lagi pada hasil pemetaan terbaru, namun ditemukan zona baru yakni zona D2 dan E2 yang tidak ada di pemetaan sebelumnya. Peta agroklimat yang dihasilkan dapat menjadi salah satu acuan dalam penentuan pola tanam di setiap wilayah sesuai dengan zona agroklimatnya.
