Sistem Perbenihan Padi Dan Karakteristik Produsen Benih Padi Di Jawa Timur

EnglishRice seed is a promising business. Partnership between rice seed producers and seed growers is profitable to both parties and enhances production scale. This study was conducted in November 2013 in Mojokerto and Banyuwangi Regencies, East Java Province. Results of the study showed that rice seed producers in East Java were able to supply more than the rice farmers' dema nd in the province. Some of the rice seed production was sold to other provinces. Partnership between producers and growers are intended to reduce risks. Furthermore, growers received soft loans fr om producer, attained higher yield, and better selling price. It is necessary to improve role of Food Crops and Horticulture Seed Control Agency (UPT PSBT PH) to oversee rice seed production and its distribution. Crops Seed Controller (PBT) enhancement will improve role of UPT PSBTPH. IndonesiaProduksi benih padi merupakan bisnis yang relatif menjanjikan. Kemitraan antara produsen dan penangkar benih padi menguntungkan kedua belah pihak dan dapat meningkatkan skala produksi. Penelitian ini dilakukan pada bulan November 2013 di Kabupaten Mojokerto dan Kabupaten Banyuwangi, Provinsi Jawa Timur. Hasil penelitian menunjukkan bahwa produsen benih di Jawa Timur mampu menghasilkan benih padi untuk mencukupi kebutuhan petani di provinsi tersebut, bahkan sebagian dijual ke luar provinsi. Umumnya produsen benih bermitra dengan penangkar benih untuk mengurangi risiko kerugian. Penangkar benih diuntungkan karena mendapat bantuan pinjaman dari produsen sehingga dapat menghasilkan calon benih padi dengan produktivitas tinggi dan harga jual yang lebih baik dari gabah konsumsi. Peranan Balai Pengawasan dan Sertifikasi Benih (BPSB) atau Unit Pengelola Teknis Pengawasan dan Sertifikasi Benih Tanaman Pangan dan Hortikultura (UPT PSBTPH) perlu ditingkatkan dalam mengawasi produksi benih sejak di lapang, setelah panen hingga pengolahan benih dan peredaran di pasar. Penambahan Pengawas Benih Tanaman (PBT) dapat meningkatkan peran BPSB

Analisis Dan Simulasi Video Watermarking Menggunakan Metode Dual Tree Complex Wavelet Transform (DT-CWT) Dan Singular Value Decomposition (SVD)

Video piracy is the act of obtaining, copying, and selling or distributing videos that already had the copyright without the consent of the copyright owner. Watermarking is a process which embeds an additional information in the host video signal so that the embedded watermark cannot be seen and difficult to be erased or altered. Video watermarking in this journal used a mp4 format video and two different watermark images. Host video frames are divided into two equal lots, some of the frames are embedded by watermark image 1, and the others are embedded by watermark images 2. The methods used are Dual-Tree Complex Wavelet Transform (DTCWT) and Singular Value Decomposition (SVD). The two watermarks are embedded and extracted in each subband at a depth level 1 to level 4 DTCWT - SVD with the aim of seeking the best subband and the best level for embedding and extracting. In the extraction testing, watermarked video is given several attacks before extraction process. Based on the MOS and PSNR value the DTCWT-SVD level for embedding process is level 4, and based on the MOS and MSE value, the best extraction images are produced from the level 3. The best subband for embedding watermark are the subbands with three parts such as {1,5}{1,1}{1,2} and {1,5}{1,2}{1,2}
