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.
Kabupaten Indramayu merupakan penghasil beras tertinggi di Provinsi Jawa Barat, Indonesia. Menurut Badan Pusat Statistik (BPS), pada tahun 2021 produksi beras tahun 2020 mencapai 1.365.435,39 ton GKG (gabah kering giling). Perkembangan teknologi di bidang pangan menghasilkan berbagai jenis beras kualitas premium dan varietas beras yang tahan terhadap perubahan iklim, seperti Ciherang, Inpari 32 HDB dan IR 64. Pemantauan rutin varietas beras tertentu di area yang luas efektif menjaga kualitas dan kuantitas beras. produksi. Penelitian ini menggunakan data penginderaan jauh untuk memantau kondisi dan distribusi padi berdasarkan metode spectral unmixing. Metode spektral unmixing digunakan untuk mengidentifikasi persentase keberadaan objek murni dalam piksel. Hasil yang diperoleh pada penelitian ini adalah citra fraksi anggota akhir varietas padi dan areal varietas padi dominan yang digunakan di Kabupaten Indramayu. Varietas dominan yang terdeteksi dengan hasil pengolahan adalah varietas Inpari 32 HDB dengan luas 30.738,64 hektar. Sebagai perbandingan, varietas selain Inpari 32 HDB juga terdeteksi di beberapa wilayah di Kabupaten Indramayu, dengan luas 12.192,68 hektar.
