Identification of Paddy Varieties from Landsat 8 Satellite Image Data Using Spectral Unmixing Method in Indramayu Regency, Indonesia

Abstract

Indramayu Regency is the highest rice producer in West Java province, Indonesia. According to the Central Statistics Agency (BPS), in 2021, rice production in 2020 reached 1,365,435.39 tons of GKG (milled dry grain). Technological developments in the food sector produce various kinds of premium quality rice and rice varieties resistant to climate change, such as Ciherang, Inpari 32 HDB and IR 64. The regular monitoring of specific rice varieties over large areas effectively maintains the quality and quantity of rice production. This study used remote sensing data to monitor rice conditions and distribution based on the spectral unmixing method. The spectral unmixing method was used to identify the percentage of the presence of a pure object in a pixel. The results obtained in this study were images of the endmember fractions of rice varieties and areas of dominant rice varieties used in the Indramayu district. The dominant variety detected with the processing results was the Inpari 32 HDB variety, with an area of 30,738.64 hectares. In comparison, varieties other than Inpari 32 HDB were also detected in several areas in the Indramayu district, with an area of 12,192.68 hectares.

Identifikasi Varietas Jagung dari Data Citra Satelit Menggunakan Metode Linier Spectral Unmixing (Studi Kasus: Kabupaten Ngawi)

“…Berdasarkan latar Belakang yang telah diuraikan, penelitian ini ditujukan untuk mengklasifikasikan sebaran lahan jagung dan sebaran varietas tanaman jagung dari data citra satelit Landsat-9 menggunakan metode Linier Spectral Unmixing dan Random Forest, dan citra Sentinel-2 digunakan untuk mengetahui fase dan pola tanam jagung dengan algoritma NDVI dan NDWI (Li & Chen, 2018). Dengan menggunakan alat Spektrometer Optics USB4000 untuk pengukuran spectral endmember di lapangan yang dapat dari varietas jagung (Cipta et al, 2022). Hasil yang diharapkan dari penelitian ini adalah peta informasi spasial yang dapat memberikan gambaran terkait sebaran lahan jagung dan sebaran varietas tanaman jagung, serta dilakukan uji akurasi hasil pengolahan penelitian di Kabupaten Ngawi.…”
