Abstract

Black rice Cempo Ireng is a local variety with a long plant life, high plant posture, and low productivity. Plant breeding by gamma irradiation was carried out to correct these weaknesses. The results of the gamma irradiation process included a selection process for each generation and produced potential lines numbers such as 8, 51, and 52. The characterization was based on the NDUS (Novelty, Distinctiveness, Uniformity, and Stability) test. The purpose of this study was to characterize potential lines as one of the requirements for the release of plant varieties. The study was conducted in the paddy fields of Pakahan Village, Jogonalan District, Klaten Regency, from February-July 2022. The method used was a single factor randomized complete block design with three replications. Data were analyzed by T test with 5% level. The results of the study showed that the three potential lines have differences with the parent and the Sembada varieties. Three potential lines can be deemed to be new, dictinct, uniform, and stable.

Abstract

Sustainable agriculture is the management and conservation of natural resources, oriented to technological and institutional changes carried out in such a way as to ensure the fulfillment and satisfaction of human needs in a sustainable manner for present and future generations. Food independence is the ability of the state and nation to produce diverse food from within the country which can ensure the fulfillment of sufficient food needs. Basically the food must be available at all times and to be able to meet the criteria for food security. Food availability is determined by 3 main aspects, namely production (quantity), distribution (accessibility), and consumption (nutritious and safe). In addition, renewable energy can come from agricultural materials. The energy crisis that occurs today is caused by an imbalance in the demand for energy that continues to increase with energy supply that is dependent on non-renewable fossil fuels, such as oil, coal and natural gas. This dependence is a serious threat to the world because of the known depletion of petroleum reserves, the instability of oil prices, and the pollution of greenhouse gases due to the burning of fossil fuels. The energy crisis will result in losses, both material and immaterial, such as loss of investor and consumer confidence, hampered creativity, inefficiency, and the risk of social unrest. The solution that is usually offered to overcome the energy crisis that occurs is the development and use of alternative energy sources, one of which is biofuels or biofuels.
