Abstract
Berdasarkan data Badan Pusat Statistik (BPS) tahun 2021, produksi padi Kabupaten Indramayu menunjukkan bahwa produksi padi di Kabupaten Indramayu pada tahun 2020 mencapai 1.365.435,39 ton GKG (Gabah Kering Giling), dengan tingkat produktivitas 6,07 ton/ha hal tersebut menempatkan Kabupaten Indramayu pada peringkat pertama sebagai produsen padi tertinggi di Provinsi Jawa Barat. Perkembangan teknologi dalam sektor pangan menghasilkan berbagai macam beras berkualitas premium dan varietas padi yang tahan terhadap dinamika perubahan iklim. Varietas padi unggul yang dominan ditanam di Indonesia diantaranya adalah Ciherang, Inpari 32 HDB, dan IR 64. Penginderaan jauh dapat digunakan untuk memperoleh informasi tersebut salah satunya menggunakan metode spectral unmixing. Metode spectral unmixing digunakan untuk mengidentifikasi besarnya persentase keberadaan suatu objek murni (endmember) dalam suatu piksel. Pada awalnya metode tersebut dikembangkan untuk menginterpretasi data hiperspektral, namun dalam perkembangannya juga diterapkan untuk menganalisa citra multispektral. Hasil yang diperoleh dari penelitian ini adalah citra fraksi endmember varietas padi dan luasan varietas padi dominan yang digunakan di kabupaten Indramayu. Dimana, varietas dominan yang terdeteksi dari hasil pengolahan adalah varietas Inpari 32 HDB, dengan luasan sebesar 30.738,64 hektar, sedangkan untuk varietas selain Inpari 32 HDB juga terdeteksi di beberapa wilayah di kabupaten Indramayu dengan luasan sebesar 12.192,68 hektar. Namun, setelah dilakukan validasi menggunakan beberapa titik sampel yang tersebar di Kabupaten Indramayu didapatkan hasil yang berbeda dengan hasil pengolahan data yang dilakukan. Pada hasil pengolahan data diidentifikasi bahwa di Kabupaten Indramayu varietas dominan yang digunakan adalah varietas Inpari 32 HDB. Namun, berdasarkan titik sampel validasi lapangan yang didapat, beberapa lahan menggunakan varietas lain selain Inpari 32 HDB. Perbedaan hasil yang diperoleh tersebut dapat didasarkan oleh beberapa faktor diantaranya adalah resolusi spasial citra serta ketersedian pustaka spektral yang digunakan.

Based on data from the Central Statistics Agency (BPS) in 2021, rice production in Indramayu Regency shows that rice production in Indramayu Regency in 2020 reaches 1,365,435.39 tons of GKG (Milled Dry Grain), with a productivity level of 6.07 tons/ha, this puts Indramayu Regency is ranked first as the highest rice producer in West Java Province. Technological developments in the food sector produce various kinds of premium quality rice and rice varieties that are resistant to the dynamics of climate change. The dominant superior rice varieties grown in Indonesia include Ciherang, Inpari 32 HDB, and IR 64. Remote sensing can be used to obtain this information, one of which is using the spectral unmixing method. The spectral unmixing method is used to identify the percentage of the presence of a pure object (endmember) in a pixel. Initially the method was developed to interpret hyperspectral data, but in its development it is also applied to analyze multispectral images. The results obtained from this study are the image of the endmember fraction of rice varieties and the area of the dominant rice varieties used in Indramayu district. Where the dominant variety detected from the processing results was the Inpari 32 HDB variety, with an area of 30,738.64 hectares, while for varieties other than Inpari 32 HDB were also detected in several areas in Indramayu district with an area of 12,192.68 hectares. However, after validation using several sample points spread across Indramayu Regency, the results were different from the results of data processing carried out. The results of data processing identified that in Indramayu Regency the dominant variety used was the Inpari 32 HDB variety. However, based on the field validation sample points obtained, some land uses other varieties other than Inpari 32 HDB. The difference in the results obtained can be based on several factors including the spatial resolution of the image and the availability of the spectral library used.
