Padi merupakan sumber bahan pangan pokok, yang dikonsumsi lebih dari 95% penduduk Indonesia. Kebutuhannya terus meningkat tiap tahun, namun belum berhasil dicukupi dari produksi sendiri, sehingga masih bergantung impor hingga 1.347.856 ton per tahun. Upaya yang dapat dilakukan selain impor, adalah peningkatan produksi padi melalui ekstensifikasi dan intensifikasi pertanian. Namun 72,98% daratan Indonesia yang sesuai untuk pertanian merupakan lahan kering, tentu akan menghambat peningkatan produksi padi. IPTEK Nuklir dapat berperan dalam optimalisasi pemanfaatan lahan kering, dimana keterbatasan keragaman alami dalam pemuliaan tanaman padi toleran kekeringan, dan polimerasi serta grafting polimer superabsorben, keduanya dapat diperbaiki melalui radiasi pengion. Kombinasi teknologi mutan padi toleran kekeringan dan polimer superabsorben sangat potensial sebagai satu diantara upaya-upaya untuk meningkatkan produksi padi. Namun, upaya penerapan teknologi tersebut tentu akan menimbukan masalah karena lemahnya diseminasi teknologi inovatif, dan lambatnya adopsi teknologi. Diperlukan perhatian yang lebih besar dari peneliti, pengambil kebijakan, dan masyarakat pengguna.

The available natural diversity highly limits the effort to improve the production of upland-rice with delicious and aromatic flavors. However, the mutagenesis can help improving the natural diversity. The aromatic-upland rice seeds, cv. Inpago Unsoed 1, were soaked in solution of NaN3 with the doses of 0 mM, 1 mM, 2 mM, 3 mM, 4 mM, 5 mM, 6 mM, 7 mM, 8 mM, 9 mM, and 10 mM, in four replications in completely randomized design. The observation included LD50, germination percentage at first-count and final-count. Data were tabulated and analyzed with CurveExpert 1.4 software for LD50, and generalized linear model in the PROC-GLM procedure of SAS 9.1 software. The means were generated and compared through Dunnett option, at probability level of 5%, in order to determine the difference in means between mutated and non-mutated seeds. The results show that the attributes of rice physiology affected by mutagenesis are sensitivity of rice to NaN3 with LD50 at 8.84 mM, and significant effect of NaN3 on the decreasing capacity of seed germination at > 6 mM for first count, and > 7 mM for final count.Keywords: germination, inpago unsoed 1, median lethal dose, rice, sodium azide

Kendala abiotik seperti salinitas, merupakan tantangan utama yang menjadi pembatas produktivitas tanaman padi. Sifat toleran salinitas sangat kompleks dan melibatkan banyak gen. Oleh sebab itu sangat sulit menyimpulkan bagaimana tanaman padi merespon cekaman salinitas. Artikel ini bertujuan untuk menjelaskan kontribusi genomika dalam penemuan gen toleran salinitas tanaman padi. Saat ini, genomika telah berkontribusi dalam penemuan gen toleran salinitas tanaman padi, khususnya melalui genomika komparatif dan kajian asosiasi lintas genom. Pengembangan pangkalan data genom juga bermanfaat untuk mengidentifikasi famili gen yang berkaitan dengan toleransi salinitas antar spesies berdasarkan homologi dan sintaksis. Gen-gen toleran salinitas yang ditemukan dapat dimanfaatkan melalui silang balik berbantuan penanda, seleksi berbantuan penanda, dan seleksi genomik, namun hingga saat ini gen-gen tersebut belum secara optimal dimanfaatkan. Penggunaan teknik baru, seperti rekayasa genetika dan pengeditan genom juga menjadi metode baru dan cepat untuk menghasilkan tanaman padi toleran salinitas. Meskipun demikian, kedua pendekatan tersebut juga belum banyak memanfaatkan gen-gen toleran salinitas yang telah ditemukan. Tren penelitian pangkalan data berbasis web diperkirakan akan terus meningkat karena murah, relatif mudah, dan mampu menghasilkan data prediktif. Pangkalan data yang akan terus berkembang, tentu harus dapat dimanfaatkan oleh peneliti dan pemulia tanaman di Indonesia.

AbstrakKetahanan pangan mensyaratkan kondisi tercukupinya pangan bagi seluruh elemen masyarakat, berkualitas, aman, beragam, bergizi, merata, serta mudah dijangkau. Rumah tangga memiliki peran penting sebagai satu diantara banyak faktor pendukung terwujudnya ketahanan pangan nasional, misalnya dengan pembentukan Rumah Pangan Lestari (RPL) yang berwawasan pertanian organik.Selain memiliki nilai ekonomi, kesehatan, dan ekologi, pembentukan RPL juga akan mengoptimalkan pemanfaatan pekarangan dan ruang-ruang sempit di sekitar rumah. Artikel ini merupakan rangkuman dari satu diantara beberapa kegiatan Kuliah Kerja Nyata - Pembelajaran Pemberdayaan Masyarakat(KKN-PPM UNDIP) di desa Montongsari, kabupaten Kendal. Kegiatan ini bertujuan untuk memberdayakan kelompok ibu-ibu rumah tangga yang tidak bekerja, untuk memanfaatkan limbah biogas atau biosurry sebagai pupuk organik dalam budidaya tanaman dengan teknik vertikultur di sekitar rumah. Metode yang digunakan adalah survei, penyuluhan, pelatihan, dan pendampingan pembuatan RPL dengan memanfaatkan bioslurry. Hasil kegiatan ini memberikan dampak positif bagi masyarakat, yaitu mulai timbul kesadaran dan perubahan perilaku masyarakat. Bioslurry yang sebelumnya belum dimanfaatkan, dapat diaplikasikan sebagai pupuk organik. Lahan kosong di sekitar rumah dan sepanjang kiri-kanan jalan yang selama ini tidak dimanfaatkan, mulai dimanfaatkan sebagai kawasan yang menunjang pangan masyarakat. Lingkungan yang dulu terkesan gersang berubah menjadilebih asri. Oleh sebab itu untuk mendukung keberlanjutan RPL, diperlukan keinginan yang serius dan tindakan nyata dari pemerintah dan masyarakat.Kata kunci: Bioslurry, Kelestarian Lingkungan, Organik, Pangan, Rumah Pangan LestariAbstractFood security exist when all people at all times have access to sufficient, safe, and nutritious food.

The effort to fulfill the need of rice through the improvement of dryland productivity can be viewed as a more environmentally-friendly way. This research used 36 rice genotypes in M1 generation that were grown hydrophonically under drought stress level of -0.03 MPa. The identifications were conducted based on peroxidase isozyme marker. The isozyme patterns in zymogram were binary-coded by visual scores for each genotype, based on the thickness and the number in the appearance of bands on certain migration distance. The migration distances were measured based on values of Rf. The similarity coefficients were calculated using Dice’s coefficient that were used to construct dendrogram using the UPGMA employing the SAHN from the NTSYSpc 2.02. The results showed that the most resistant genotype under drought stress was R-4, and the genetic relationships among the genotypes were divided into two main groups, aromatic and non-aromatic group, in which some genotypes experienced the reduced levels of aromatic character (R-8 and R-9) and the drought resistance character (IU-2, IU-3, IU-4, IU-5, IU-6, IU-7, and IU-8), but there were some genotypes to able to improve the resistance under drought stress (R-2, R-3, R-5, R-6, R-7, IT-4, IT-5, and IT-7).

Efforts to increase rice production through genetic improvement are often limited by the availability of natural diversity. That natural diversity can be improved through induced mutation. Selected characters can be observed since the germination phases, which may also indicate the plants survival under field conditions. Experimental design was arranged in split plot, with cultivars as main plot and mutagen doses as sub plot. The experiment consisted of 36 treatment combinations, with each treatment consisting of 10 replications. Data were recorded on percentage of first count, final count and germination rate. The data were analyzed using F-test by SAS 9.0 and mean separation was carried out by employing DMRT at 95 % (α = 5 %) of confidence level. The results showed that the best cultivar response for germination traits was Inpari 13, the best mutagen to build cultivar for germination traits was Gamma 150 Gy, and the best combination between cultivar and mutagen for germination traits was Inpago Unsoed 1 that was treated with Gamma 150 Gy.
