    Abstract Mineral Content of Iron on Red and Black Local Rice of Yogyakarta. Two cultivar types of rice, called red rice (Segreng. Mandel, Cempo Merah, Saodah Merah) and black rice (Cempo Ireng and Melik) are typical of Yogyakarta Province. These two types of rice contain iron mineral which is important for human health. A study to evaluate the iron content of these two locals rice of Yogyakarta, by previously planting two cultivars of the black rice (Cempo Ireng and Melik) and five cultivars of the red rice (Segreng. Mandel, Cempo Merah, and Saodah Merah) in the farmers irrigated rice field. The rice grains harvested from this crop were then dried, milled, and analysed for their iron content. Data of the iron content were analysed based on the Completely Randomized Design treatment arrangement. The different among treatments were evaluated by DMRT test at 5% level of confidence. Results of this experiment indicated that high content of iron of 150.3 and 31.8 ppm were demonstrated by the cultivars of black rice Melik and Cempo Ireng. While iron content of 18.99, 16.09, 12.84, and 12.76 ppm were observed on the cultivars of Segreng. Cempo Merah, Saodah Merah, and Mandel, respectively. The iron content of these local cultivars typical of Yogyakarta, was significantly higher as compared to that of common rice varieties which reached 11.7 ppm only. Abstrak Beberapa padi lokal beras merah (Segreng. Mandel, Cempo Merah, Saodah Merah) dan beras hitam (Cempo Ireng dan Melik). merupakan plasma nutfah padi khas Yogyakarta yang perlu dimanfaatkan. Kedua beras merah dan beras hitam ini mengandung mineral besi (Fe) yang memiliki fungsi penting untuk kesehatan manusia. Penelitian untuk mengevaluasi kadar besi beberapa beras merah dan beras hitam lokal Yogyakarta. Penelitian diawali dengan menanam dua jenis padi hitam (Cempo Ireng dan Melik) dan lima padi merah (Segreng, Mandel, Cempo Merah, dan Saodah Merah) di sawah petani. Hasil padi dari pertanaman tersebut, kemudian dijemur, digiling, dan dianalisis kandungan besinya. Data kandungan besi yang diperoleh dianalisis dengan Rancangan Acak Lengkap. Perbedaan kandungan besi antarvarietas dievaluasi dengan uji DMRT 5%. Hasil penelitian menunjukkan bahwa kadar besi yang tinggi sebesar 150,3 ppm dan 31,8 ppm berturut-turut terdapat pada beras hitam Melik dan Cempo Ireng diikuti oleh beras merah Segreng, Cempo Merah, Saodah Merah, dan Mandel. berturut-turut sebesar 18.99 ppm, 16,09 ppm, 12.84 ppm, dan 12,76 ppin. Rata-rata kadar besi pada beras merah dan beras hitam ini nyata lebih tinggi dibandingkan dengan rata-rata kadar besi pada beras varietas unggul yang mencapai 11.7 ppm.

    ABSTRACT Prospect of Farming the Melik Black Rice, in Bantul District, Yogyakarta Province. The Melik black rice, a local rice cultivar of Yogyakarta, grows only in particular areas of Yogyakarta. The taste, aroma, and the appearance characters of this locally call grown rice were novelty and specific also scarce. A survey to analysed the feasibility of growing the cultivar was carried out in the farmers' field carrying out organic rice farming in Ganjur Village, the District of Bantul during the wet season of 2008/2009. Results of the survey indicated that the B/C ratios were 1.39 and 1.58, for dried paddy and husked rice, respectively. It was concluded that, beside for the purpose of rescuing the rice germplasm, farming the black rice is profitable and possess a good prospect to be developed. Abstrak Padi beras hitam hanya tumbuh dan dibudidayakan di daerah tertentu, di Yogyakarta, memiliki nilai jual yang spesink. Sast ini, keberadaan daan beras beras hitam sudah sangat langka, bahkan hampir punah dan oleh karena itu perlu upaya untuk menyelamatkannya. Survei di lahan petani yang melakukan melak pertanaman padi organik untuk menganalisis kelayakan usahajani padi beras hitam lokal Yogyakarta telah dilaksanakan di D Ganjur, Bambanglipuro, Kabupaten Bantul pada MH 2008/2009. Hasil penelitian menunjukkan bahwa nisbah BVC usahatani padi beras hitam lokal dalam bentuk GKG dan bentuk beras berturut turut sebesar 1.39 dan 1,58. Ini berati bahwa usahatani beras hitam, di samping dapat mencegah kepunahan salah satu sumber genetik padi, dari argi ekonomi juga sangat menguntungkan dan memiliki peluang yang back untuk dikembangkan
