Keragaan Lahan Sub-Optimal dan Perbaikan Produktivitas Melalui Kebijakan Daerah di Lampung
Get PDFAgricultural land in Lampung is the land of sub-optimal as acid dry land, rainfed areas and wetlands. A study was conducted to study the extent and distribution of the lands of sub-optimal, as well as the policies of local governments in land productivity improvement. Acid dry land area of 2.7 million ha spread with 1.23 million ha is recommended for the development of food crops. Rainfed areas reported an area of 121 thousand hectares, while the area of swamp land is 108 thousand hectares which consists of tidal marsh and swamp are 56 thousand ha and 52 thousand ha, respectively. Government policies to improve the productivity of acid dry land more focused on increasing productivity of plantation crops and horticulture. While policies to increase the productivity of food crops, especially rice is more focused on the rainfed areas and wetlands. Government policies to take advantage of dry land under stands of annual crops for the attainment of food self-sufficiency is not yet visible. Program policies to optimize the productivity of rainfed and swamp land is also not optimal because it only been done on a narrow scale areas such as the provision of water pumps and drainage improvements in wetlands Sragi South Lampung, new paddy fields in Mesuji, and adaptation trials of new varieties in the swamp of Tulang BawangKeywords: sub-optimal land, acid dry land, rainfed, wetlands  Â
Analysis of Agroecology and The Requirement of Supplemental Irrigation on Cacao Plants in Lampung
Get PDF<p><em>One of the factors that affect the productivity of cacao plants is water availability. Water deficit will negatively affect the development of cacao flowers and beans. Water stress is reported as one of the causes of low productivity on plantation crops in Lampung Province. The study was aimed to analyze the characteristics of agroecology and supplemental irrigation required for growth and production of cacao in Lampung. The research was carried out in the District of Pesawaran, Tanggamus, East Lampung, and South Lampung, Lampung Province, from 2012 to 2015. The study was conducted with the survey method and literature study for the collection of the primary and secondary data, related to the characteristics of the land agroecology. Geographically, the main cacao growing areas in this region is divided into two regions, western region consist of Pesawaran and Tanggamus District and east region comprise of East Lampung and South Lampung District. Based on agroecological zones, the planting of cacao in both regions is in accordance with the recommendations of land use. However, land suitability analysis showed that some of the agroecological characteristics of land becomes a limiting factor for the growth and production of cacao, including soil pH &lt; 5.5, low cations exchange capacity (CEC) (&lt; 16 cmol(+)/kg), air humidity &gt; 75%, and in some areas there is an erosion hazard. Another obstacle is the water deficit that occurs during 140 days within 1 year of cacao growth cycle that occurred in July until mid-November. There are two factors that can be applied to increase cacao productivity in Lampung province, i.e. (1) an improvement of cacao cultivation technology that can address the characteristics of agroecology as a limiting factor of growth, and (2) an application of a supplemental irrigation technology to avoid cacao from water stress. The requirement of supplemental irrigation is 340.5 mm in western region and 209.7 mm in eastern region of Lampung.</em></p></jats:p

Optimasi Potensi Lahan Kering untuk Pencapaian Target Peningkatan Produksi Padi Satu Juta Ton di Provinsi Lampung
Get PDFProgram upaya khusus (UPSUS) peningkatan produksi padi yang dicanangkan Kementerian Pertanian memberi tugas kepada Provinsi Lampung untuk meningkatkan produksi padi dari 3,3 juta ton pada tahun 2014 menjadi 4,3 juta ton pada 2017. Tugas tersebut merupakan tantangan yang cukup berat bagi petani dan pengambil kebijakan di daerah tersebut karena permasalahan hasil pelaksanaan Program Sekolah Lapang Pengelolaan Tanaman Terpadu (SL-PTT) di lahan sawah, program tersebut hanya mampu meningkatkan produktivitas padi 200–300 kg/ha. Peluang yang cukup terbuka tetapi belum dimanfaatkan secara optimal adalah pengembangan padi gogo di lahan kering suboptimal. Saat ini luas panen padi gogo baru 47.981 ha dan hasilnya berkontribusi sekitar 4,5% terhadap total produksi padi di Lampung. Luas panen padi gogo tersebut berpotensi ditingkatkan karena di daerah ini tersedia lahan kering yang sesuai untuk pengembangan padi gogo seluas 802.341 ha. Dengan perluasan areal tanam menjadi 100.000 ha dan peningkatan produktivitas dari 3 menjadi 5 t/ha dengan menggunakan berbagai varietas unggul baru spesifik lokasi, serta pendampingan terhadap aplikasi teknologi pengelolaan lahan seperti penggunaan pembenah tanah, sistem tanam jajar legowo, dan pemupukan, peningkatan produksi padi sekitar 300 ribu ton dari target yang ingin dicapai sebesar 1 juta ton pada tahun 2017 dapat dipenuhi dari lahan kering

The pattern cultivation especially fertilization also different from each other in each type of land swamp and a specific location, so have an effect on yield. This study had done by the method survey and interviews farmers by using a questioner. Location interview was in three districts that have land swamp area in Lampung, namely Tulang Bawang District (Sub District: Rawa Jitu Selatan, Rawa Pitu, and Penawar Aji); Mesuji District (Sub District: Mesuji Timur and Mesuji); and Lampung Selatan District (Sub District: Rawa Sragi). The number of respondents 15 farmers per sub-district, so the total respondents were 90 farmers. The data were obtained then tabulated and analyzed descriptively. Most of the farmers used these wetlands for rice farming, but only 50% can be used for double cropping of rice per year. The dose of fertilizer farmers applied both urea and NPK Ponska / SP-36 lower than recommended dosage according to Permentan Regulation No. 40 of 2007 (Urea 175 kg + 200 kg Ponska NPK + 25 kg SP-36 + 50 kg KCl). Average rice yield was obtained according to the results of interviews 4.34 t/ha in MT I and 2.5 t/ha in MT II

No full textAbstractTidal swampland is a marginal land that has significant potentials for the development of food crops, although its exploration will face several constraints such as low pH, high content of iron (Fe2+), low phosphorus (P), shallow pyrite (FeS2) layer, high salinity, and excess water. The objective of this study was to investigate the effect of biofertilizer and saturated soil cultivation in improving nutrient use efficiency and productivity of soybean in the tidal swamp. The field experiment was arranged in a splitsplit plot design with 2 x 3 x 4 treatments and 3 replications respectively. The treatment in the main plot was soybean cultivation techniques (B) consisting of farmer’s cultivation method (B1) and saturated soil cultivation (B2). The subplot treatment was soybean superior varieties consisting of Anjasmoro (V1), Argomulyo (V2) and Grobogan (V3) and the sub-subplot treatment was fertilization (P) consisting of a 100% of standard dose of NPK (P1) and the use of biological fertilizers (1 kg) combined with NPK; 100% of standard dose (P2), 75% of the standard dose (P3), and 50% of the standard dose (P4) per hectare. The results showed that Bradyrhizobium japonicum R6 and Aeromonas punctata RJM3020 as an active ingredient of biofertilizer was effective to reduce chemical fertilizer NPK up to 50% of the standard dose commonly applied to soybean cultivation by farmers. Anjasmoro varieties treated with this biofertilizer and combined with 50% of standard dosages of NPK could produce up to 2.798 kg of dry beans/ha under saturated soil cultivation.Keywords: soybean, biofertilizer, saturated soil cultivation, tidal swamp Abstrak Lahan rawa pasang surut merupakan lahan marginal yang memiliki potensi cukup besar untuk pengembangan pertanian tanaman pangan, meskipun dalam pemberdayaannya berhadapan dengan beberapa kendala seperti pH tanah rendah, kandungan besi (Fe2+) tinggi, kandungan fosfor (P) rendah, lapisan pirit (FeS2) relatif dangkal, kadar salinitas tinggi, dan volume air berlebih. Tujuan dari penelitian ini adalah menguji kemampuan pupuk hayati dan budidaya jenuh air dalam memperbaiki efisiensi penggunaan hara dan produktivitas kedelai di lahan rawa pasang surut.
