<p><em><strong>Opportunity to Increase Rice Production in Fresh Water Swampy Land in Lampung</strong></em></p><p>The area of fresh water swampy land in Lampung in 2012 was 55,714 ha with rice productivity of 5.13 t/ha so it is possible to be increased. The article discusses opportunity to increase rice production in fresh water swampy land in Lampung. Increasing rice yield can be done by enhancing cropping index and land productivity, lowering yield gap and decreasing yeld loss. Cropping index in fresh water swampy land can be increased by cultivating rice with surjan system, while rice yield is increased by integrated crop management (ICM) which its components include the use of improved varieties, planting with legowo 2: 1 or 4: 1, fertilizer application according to plant need, water management to prevent rice plant from submerging or drought, and integrated pest management. Rice yield gap is decreased by implementing location specific technologies and intensifying counseling to farmers, while yield loss is lowered by applying integrated pest management and using agricultural tools and machineries in rice farming. These production increases have an impact on the regional and national food availability in an effort to achieve rice self-sufficiency.</p><p>Keywords: Rice, production, fresh water swampy land, growth source</p><p align="center"><strong><br /></strong></p><p align="center"><strong>ABSTRAK</strong></p><p>Luas lahan rawa lebak di Provinsi Lampung pada tahun 2012 mencapai 55.714 ha dengan tingkat produktivitas padi 5,13 t/ha sehingga masih berpeluang ditingkatkan. Tulisan ini membahas peluang peningkatan produksi padi di lahan rawa lebak di Lampung. Peningkatan produksi dapat dilakukan melalui peningkatan indeks pertanaman (IP) dan produktivitas lahan, mengurangi senjang hasil, dan menurunkan kehilangan hasil. Indeks pertanaman di lahan rawa lebak dapat ditingkatkan dengan menerapkan sistem surjan. Sementara produktivitas ditingkatkan melalui pengelolaan tanaman terpadu (PTT) dengan komponen teknologinya antara lain penggunaan varietas unggul baru, cara tanam legowo 2:1 atau 4:1, pemberian hara sesuai kebutuhan tanaman, pengelolaan tata air sehingga tanaman padi terhindar dari terendam atau kekeringan, serta pengelolaan hama dan penyakit secara terpadu. Penurunan senjang hasil dapat dilakukan dengan menerapkan teknologi spesifik lokasi dan mengintensifkan penyuluhan ke petani. Sementara kehilangan hasil dapat dikurangi melalui penerapan pengelolaan hama dan penyakit secara terpadu dan penggunaan alat dan mesin pertanian pada kegiatan usaha tani. Peningkatan produksi ini akan berdampak pada peningkatan ketersediaan pangan daerah dan nasional dalam upaya mencapai swasembada beras.</p><p>Kata Kunci: Padi, produksi, rawa lebak, sumber pertumbuhan</p><p> <em></em></p>
The research objective was to increase upland rice yield and balancing it with efforts of land conservation to maintain sustainable land productivity. It has been conducted in the research station of Lampung Assessment Institute for Agricultural Technology (AIAT). The treatments were arranged in a factorial randomized block design with three replications. The treatment in the main plot was the method of tillage whereas the subplot was organic fertilizers. The tillage methods were: (1) Maximum tillage and without ditch, (2) Minimum tillage with ditch. The organic fertilizer treatments were control, bio urine plus 10 L ha−1, bio urine plus 20 L ha−1, biodecomposer 10 L ha−1, and biodecomposer 20 L ha−1. The upland rice variety was Inpago 12. The variables observed were soil water content, growth and yields of rice. The results showed that the minimum soil tillage with ditch provided a higher soil water content than the maximum tillage. Likewise, the application of liquid organic matter from local microorganisms (biodecomposer) increased soil water content compared to the control. Application of bio urine plus 20 L ha−1 significantly increased plant height and yield. The highest dry grain was obtained in the treatment of minimum tillage and biodecomposer 20 L ha−1.
Cassava is grown nowadays for use in food, feed, and industrial purposes. It is believed that the agro-industrial sector, which uses cassava as a raw material, has more advanced farming technology for improving cassava production. Lampung province in Sumatra Island, Indonesia, is one of the cassava production centers for industrial raw materials, with a planted area of 256,632 ha in 2018. The planting areas are acid soils of Ultisols, Inceptisols, and Oxisols with pH levels ranging from 4.5 to 5.0. Acidic soils have a complicated set of plant growth-limiting constraints. Essential nutrients for plant growth, such as N, P, and K, as well as other cations, are often low due to leaching, nutrients fixed by Fe/Al oxides of clay minerals, and low soil cation exchange capacity. In these acid soils, cassava production ranges from 8 to 15 t ha−1 for traditional farming, 20–24 t ha−1 for semi-developed farming to 25–35 t ha−1 for advanced farming. Meanwhile, with numerous technological advancements, cassava productivity can reach 40–50 t ha−1. Aside from improving varieties, technological updates being pursued include increasing the accuracy of mineral fertilizer dosage, improving planting system technology, bio-fertilizer technology, and in situ organic C enrichment of acid soils.
Shake flower cookies is a type of traditional Indonesian cookies made from rice flour. Processing rice groats into rice groats flour and using it as a raw material for making shake flower cookies aims to increase the added value of rice groats which has only been used as animal feed. The research was conducted in Ponco Kresno Village, Negeri Katon Subdistrict, Pesawaran District, from September to December 2016. The treatment applied was the difference in the composition of flour used, namely: A = 100% Rose Brand rice flour ; B = rice groats flour 90% + tapioca flour 10%; C = rice groats flour 80% + tapioca flour 20%; and D = rice groats flour 100%. The results showed that treatment C (rice groats flour 80% + tapioca flour 20%) could be developed for entrepreneurial shake flower cookies, because statistically it did not show a significant difference in color, taste, crispness, and general acceptance compared to the use of rose brand rice flour 100%, and the capital needed is the lowest compared to other treatments, which is only Rp. 4,860, - / pack, while the price of the selling shake flower cookies on the market for all treatments is the same, Rp. 9,000, - / pack, so that the benefits obtained by farmers when using treatment C are higher than other treatments.
This paper explores the opportunities for the development of sorghum to reduce imports of corn. Besides being the primary raw material for poultry feed, corn is the second staple-food ingredient after rice. Still, the increase in corn production is not in line with the demand for corn due to the increasing population. This condition has resulted in the need for corn to be imported, while the government has imposed an import ban since 2017. It is necessary to have other commodities that can substitute corn as food as sorghum. Sorghum farming produces not only sorghum seeds but also plant waste which can use for a ruminant feed so that the availability of ruminant feed continues. Sorghum farming needs to be developed so that the availability of food and feed can sustain. The development of sorghum should be in areas where there is a feed industry to ensure the sorghum market for farmers and the availability of raw materials. The development can also be in areas that have long consumed sorghum (local food).
