Indeks Kekeringan Spi (Standardized Precipitation Index) Dan Pengaruhnya Terhadap Produktivitas Hortikultura Tahunan Di Kabupaten Jember

Abstract: Perennial tropical horticulture is a superior product whose productivity is affected by water availability. The impact of climate fluctuations due to global warming affects the availability of ground water. This study aims to determine the effect of the Standardized Precipitation Index (SPI) drought index derived from rainfall data on the productivity of perennial horticulture (durian, avocado and rambutan). The study was conducted from July 2016 - November 2018 in 9 sub-districts in Jember Regency where has t… Show more

“…Rainfall that affects the dry/wet months will affect the quality of seasonal fruit, such as the rambutan (Nephelium sp. ), whose flesh will be thin if the dry season is too lengthy (Nugroho et al 2019). In addition, the wind substantially impacts certain seasonal fruits, such as avocado (Persea spp.).…”

“…Metode Standardized Precipitation Index (SPI) yang dikembangkan berdasarkan kuantifikasi defisit air pada berbagai skala waktu sehingga data presipitasi distandarisasi dan ditransformasikan hasil observasi ke dalam skala indeks kekeringan [10]. Klasifikasi kekeringan terjadi pada waktu SPI secara berkesinambungan bernilai negatif dan mencapai intensitas kekeringan dengan SPI bernilai -1 atau kurang, sedangkan kekeringan akan berakhir apabila nilai SPI menjadi positif [11].…”

“…Nilai SPI 12 bulan menggambarkan pola curah hujan dalam jangka panjang selama setahun, SPI 12 digunakan untuk pengamatan terhadap aliran sungai. SPI 12 bulanan merupakan perbandingan curah hujan selama 12 bulan berturut-turut dengan 12 bulan berturut-turut yang sama dalam semua data tahun yang tersedia sebelumnya [10]. Pada Tabel 5, dapat dilihat kualifikasi nilai SPI.…”
