Salah satu Nawacita pemerintah Jokowi-JK adalah mewujudkan kemandirian ekonomiÂ nasional dengan menggerakkan sektor-sektor strategis ekonomi domestik khususnya sektorÂ pertanian dalam upaya membangun dan mewujudkan kedaulatan pangan. Indonesia memiliki lahanÂ kering dan basah potensial untuk mewujudkan target pemerintah tersebut, namun demikian tidaklahÂ mudah karena sektor pertanian diperhadapkan dengan berbagai ancaman serius seperti degradasiÂ sumber daya pertanian, konversi dan alih fungsi lahan, pencemaran pertanian serta variabilitas danÂ ketidak pastian iklim serta banyaknya jaringan irigasi yang rusak. Selain itu faktor lain yang perlu mendapat perhatian adalah anomali iklim baik pada skala lokal, nasional dan global karena secaraÂ langsung dan tak langsung mempengaruhi pencapaian swasembada pangan. Kejadian banjir danÂ musim kemarau berkepanjangan merupakan faktor yang sulit dihindari dan menjadi bagian yangtidak terpisahkan dalam pembangunan pertanian khususnya pencapaian swasembada pangan. Swasembada pangan dapat dicapai antara lain harus didukung oleh ketersediaan sumber daya airÂ dan teknologi pengelolaan air. Teknologi pengelolaan air menjadi faktor kunci sukses dalam upayaÂ meningkatkan produksi guna mewujudkan swasembada pangan. Teknologi pengelolaan air yangÂ perlu dilakukan di lahan basah seperti teknologi tata air mikro dan surjan, irigasi macak-macak,Â irigasi bergilir, dan irigasi berselang (alternate wetting and drying) sedangkan teknologiÂ pengelolaan air di lahan kering meliputi konservasi tanah dan air, pengembangan embung danÂ pemanenan air, pengembangan irigasi bertekanan dan pompanisasi serta pengembangan irigasiÂ hemat air lainnya seperti irigasi tetes, saluran resapan dan pengairan separuh daerah akar

The sweet potato (Ipomoea batatas L). has significant potential as a source of carbohydrates in Indonesia The purple hue of sweet potatoes is a result of natural pigments known as anthocyanins. As antioxidants and free radical scavengers, anthocyanin chemicals have a crucial role in combating aging, cancer, and degenerative disorders. In addition, anthocyanins possess anti-mutagenic and anti-carcinogenic properties, as well as the capacity to prevent liver function abnormalities, act as antihypertensives, and reduce blood sugar levels. Given the numerous benefits of anthocyanin content, the presence of anthocyanin compounds as a source of natural antioxidants in purple sweet potatoes is highly intriguing. Alongside the growing public knowledge of healthy living, consumer food preferences are also altering. Foods that are beginning to be in high demand among consumers have an appealing appearance and flavor, as well as specialized physiological benefits for the human body. The presence of anthocyanin compounds in purple sweet potato makes this type of food very attractive to be processed into foods with functional value. On the one hand, with the increasingly limited land area, the potential for developing agricultural products, including sweet potatoes, is also increasingly limited. Meanwhile, on the other hand, the yard business model owned by households is not utilized optimally. Therefore, in providing healthy food and functional food based on anthocyanin-rich sweet potatoes, it is necessary to develop and revitalize yard land by vertically developing sweet potatoes in sacks. In addition to increase the availability of functional, healthy food, this activity is also a revitalization of the use of yardland.

Brown rice (Oryza sativa) is a highly nutritious staple food that contains anthocyanins in addition to carbohydrates, fat, protein, fiber, and minerals. Anthocyanins serve as antioxidants, playing a crucial role in plant and human health. Efforts to improve rice production, particularly upland rice production, are always coupled with efforts to increase production of brown rice. The majority of brown rice is produced from upland rice. There has been no effort to manufacture brown rice before today. Therefore, efforts to expand upland rice production with native cultivars are inextricably linked to efforts to boost upland rice output of red rice. Upland rice is brown rice consumed without going through a grinding process or the process of removing the bran and bran from the endosperm of the rice. Rice is only ground into broken rice so that the husk is still attached to the endosperm and has high nutritional value. Strong body immunity and excellent health levels are needed. One of them is by consuming healthy food that is available locally and has become a daily food menu, it only needs to increase production and processing efforts so that it is always healthy. Upland brown rice can be planted as an intercrop to maximize land use for plantation crops, so it has the potential to be developed in Southeast Sulawesi because there is still a lot of unused land or land that has not been used optimally. Therefore, in the context of providing healthy food and functional food based on upland red rice, which farming families can reach, and close to the location of the farmers' livelihoods, it is necessary to increase brown rice production through the introduction of brown rice cultivation technology as a garden plant and also as a family medicinal plant.

In order to develop soybean plants, the availability of water in the form of soil moisture is one of the factors that give a very important message. Water supply is usually obtained from rainwater, so the arrangement of cropping pattern often follows the pattern of rainfall distribution that occurs. Preparation of water balance is intended to increase the productivity of dry land through the determination of pattern and planting schedule in accordance with groundwater availability. The water balance analysis using climate data series includes monthly rainfall and air temperature. Climate data obtained from Climatology Station Wolter Monginsidi Kendari Southeast Sulawesi. The opportunity for rainfall is exceeded and the water balance is analyzed using statistical methods. The results show that the soil moisture conditions are available for the crops for 8 months, ie from December 10 daily 2 to July 10 daily 2. while the water deficit in August to November (during dry season). Thus the cultivation can be done for 8 months ie when a surplus of water.

The aim of this research was to know the effect of urea fertilizer on growth and yield of mustard plant. This research was carried out at the Experimental farm of Agriculture Faculty, Haluoleo University, from October to November 2012. This research was carried out using completely randomized block design, that consisted of 6 treatments namely: without Urea fertilizer (U0), 25 kg ha-1 equals to 1.6 g plot1 of urea fertilizer (U25), 50 kg ha-1 equals to 3,2 g plot-1 of urea fertilizer (U50), 75 kg ha-1equals to 4,8 g plot-1of urea fertilizer (U75), 100 kg ha-1 equals to 6,4 g plot-1 of urea fertilizer (U100),125 kg ha-1 equals to 8 g plot-1 of urea fertilizer (U125) . Each treatment was repeated 3 times which resulted in 18 experiment units. The experiment data were analyzed using analysis of variance method and then followed by Honest Significantly Difference Test. The result of the research showed that the application of various dosages of urea fertilizer has an effect on the growth and yield of mustard plant. The application of urea fertilizer to mustard plant effected plant height, leaf area at the age of 21 and 28 days after planting, dry weight of root, dry weight of leaves and relative growth rate. However, the application of urea fertilizer has no effect on the number of leaves, leaf area at the age of 14 days after planting, leaf fresh weight, and the root fresh weight of mustard plant. An increase in the dosages of Urea fertilizer was followed by an increase in the growth and production of mustard plant. 125 kg ha-1 urea fertilizer increased growth and production of mustard plant a lot higher compared to other of urea fertilizer with a production yield of 10 ton ha-1.
