Abstract

Rainwater harvesting is a water conservation measures. Water is harvested in addition to reducing runoff, and erosion control can be used as a supplemental source of irrigation for crops on marginal land. A study was conducted to test the effectiveness of a small pool of rainwater harvesting usually termed as a small farm reservoir (SFRs) as a complementary source of irrigation water in improving the productivity of farming on marginal land. The experiment was conducted from December 2005 to August 2007 in Buanasakti, East Lampung, Indonesia. Three SFRs with a volume of 7 x 3 x 2.5 m (50 m3 were made ??on upland at sloping area (8-15%) of ??1.5 ha. Further rain was deposited to be used by farmers for crop watering, especially in the early dry season. Extensive planting of crops that can be irrigated with SFRs, based on consideration of the farmers themselves. Observation result indicated that the SFRs were used by the farmers to water the vegetables and tobacco plants with different extents. However, on average, the presence of SFRs increased the planting area of vegetables such as beans and cucumbers in the dry season to 650%. Increased intensity of cultivation of vegetables and tobacco cultivation also increase farmers' income of 1.5 ha of marginal land as much as 37.49%.   Keywords: small farm reservoir, supplemental irrigation, vegetables, marginal land

Abstract

Stabilitas agregat menentukan kualitas tanah dan polisakarida adalah agen agregasi utama partikel tanah. Penelitian bertujuan mempelajari stabilitas agregat dan polisakarida sebagai agen agregasi partikel tanah masam yang diperlakukan dengan Brachiaria decumbens (BD), mikoriza dan kompos jerami diperkaya kalium di Kebun Percobaan Tegineneng BPTP Lampung. Penelitian ini menggunakan rancangan acak lengkap faktorial 3 faktor. Faktor 1, rumput Brachiaria decumbens, yaitu tanpa B. decumbens (B0) dan dengan baris B. decumbens (B1); faktor 2, mikoriza yaitu tanpa mikoriza (M0) dan dengan inokulasi mikoriza (M1); dan faktor 3, kompos jerami diperkaya kalium yaitu kompos 2 ton ha-1 masing-masing diperkaya KCl masing-masing 0 kg ha-1 (K0), 50 kg ha-1 (K50), 100 kg ha-1 (K100) dan 200 kg ha-1 (K200). Hasil penelitian menunjukkan perlakuan BD dan interaksi BD dan mikoriza mendorong fragmentasi agregat makro menjadi agregat meso dan mikro, namun stabilitas agregat dibawah pengaruh perlakuan tersebut lebih baik dibanding stabilitas agregat tanah kontrol. Inokulasi mikoriza memperbaiki stabilitas agregat makro 1-2 mm. Pengayaan kalium pada kompos jerami secara rata-rata tidak berpengaruh terhadap stabilitas agregat tetapi dalam interaksi dengan B. decumbens, pengayaan kompos jerami dengan 100 dan 200 kg KCl ha-1 berpengaruh cukup baik terhadap stabilitas agregat makro 2-5 mm. Polisakarida total di dalam agregat tanah pada perlakuan interaksi B. decumbens dan mikoriza nyata meningkat, demikian juga polisakarida bukan selulosa cenderung lebih baik. Perlakuan B. decumbens meningkatkan kadar polisakarida total di dalam agregat meso (0.25-1 mm) dan mikro (0.05-0.25 mm), sedangkan mikoriza meningkatkan polisakarida total dan polisakarida bukan selulosa di dalam agregat makro (> 1 mm).

Abstract

ABSTRAKProduktivitas kelapa sawit rakyat di Provinsi Lampung masih relatifrendah dibanding potensi produktivitas optimal. Berkenaan dengan hal itu,dari bulan Februari sampai dengan September 2012 dilakukan kajiandengan tujuan mengidentifikasi karakteristik agroekologi dan teknispengelolaan kebun kelapa sawit rakyat yang berpeluang diperbaiki agarproduktivitas kebun kelapa sawit rakyat meningkat. Kebun kelapa sawitrakyat yang diidentifikasi dipilih secara acak di tujuh kabupaten diProvinsi Lampung. Pengumpulan data dilakukan melalui survei danwawancara petani. Rata-rata produksi tandan buah segar (TBS) kebunkelapa sawit rakyat di Lampung masih rendah (15 ton/hektar/tahun).Produksi ini berpeluang ditingkatkan melalui penerapan teknologi yangdapat mengatasi sifat-sifat agroekologi sebagai faktor pembataspertumbuhan dan produksi kelapa sawit, seperti ketersediaan air, retensihara, dan bahaya erosi. Teknologi yang dibutuhkan untuk mengatasikendala tersebut antara lain membangun irigasi suplemen, meningkatkankemampuan tanah dalam menyimpan air, memperbanyak penggunaanbahan organik dan kapur, serta mengaplikasikan teknologi konservasitanah dan air. Produktivitas kebun kelapa sawit rakyat akan berpeluangmeningkat  seiring  dengan  bertambahnya  umur  tanaman,  sertameningkatnya penggunaan pupuk organik untuk tanaman yang telahmenghasilkan (TM) dan pupuk NPK untuk tanaman belum menghasilkan(TBM). Pembinaan petani perlu diintensifkan untuk meningkatkankesadaran petani akan pentingnya memupuk TBM. Hasil analisismengindikasikan bahwa pemupukan NPK untuk TBM berkorelasi positifdengan produktivitas kelapa sawit.Kata kunci: Elaeis guineensis Jacq., agroekologi, pengelolaan kebunkelapa sawit rakyat, produktivitasABSTRACTProductivity of smallholder oil palm in Lampung province is stillrelatively low compared to the potential for optimal productivity. A studywas conducted with regard to that, from February to September 2012 toidentify the agroecological characteristics and technical management ofsmallholder oil palm plantations that likely to be improved in order toincrease the productivity of oil palm of smallholder. Smallholderplantations studied were randomly selected, each 1 sites in seven districtsin Lampung Province and data collection was conducted through surveysand interviews of farmers. Average production of fresh fruit bunches(FFB) of smallholder oil palm plantations in Lampung are still low (15tons/hectare/year). The production is likely to be enhanced through theapplication of technology that is able to cope with the nature ofagroecology as the constraints of growth and production of oil palm,namely the availability of water, nutrient retention, and erosion hazard.The technology needed to overcome the obstacles include supplementingirrigation, increasing the soils ability to store water, multiplying the useof organic materials and lime, and applying soil and water conservationtechnologies. Besides that, oil palm productivity of smallholder likelyincrease, along with the increasing age of the plant, the growing use oforganic fertilizer for plants that have produced (TM) and NPK fertilizerfor immature plants (TBM). Development of farmers needs to beintensified to increase farmers awareness of the importance of fertilizingthe TBM. The results of the analysis indicated that NPK fertilization forTBM positively correlated with the productivity of oil palm.Keywords: Elaeis guineens

Abstract

Sumbangan usaha tani kopi terhadap kegiatan ekonomi penduduk tidak terbatas pada produksi kopi semata, tetapi juga lapangan pekerjaan di sektor perdagangan dan jasa. Kopi umumnya dibudidayakan dalam skala kecil. Namun, lahan untuk usaha komoditas perkebunan umumnya berupa lahan kering masam sehingga produktivitas tanaman rendah. Hal ini karena lahan kering masam mengandung Al tinggi yang dapat meracuni tanaman dan mengganggu penyerapan hara, miskin hara terutama N, P, K, Ca, dan Mg, miskin bahan organik, dan miskin mikroba tanah sehingga kurang subur. Oleh karena itu, penggunaan lahan kering masam untuk usaha pertanian perlu didukung teknologi pengelolaan sumber daya lahan seperti benih unggul toleran tanah masam, pemupukan berimbang, serta konservasi tanah dan air untuk lahan berlereng. Inovasi teknologi untuk komoditas perkebunan di lahan kering masam sudah tersedia. Agar teknologi tersebut dapat diterapkan di lapangan telah disusun suatu model yang terdiri atas empat kegiatan, yaitu (1) konservasi, yaitu pengembangan agribisnis kopi dalam perspektif konservasi lahan dan agroforestri, (2) perbaikan teknik budi daya melalui peremajaan dengan klon-klon unggul yang didukung kebun entres, (3) penanganan pascapanen untuk meningkatkan kualitas biji kopi, dan (4) penguatan kelembagaan petani melalui peningkatan dinamika kelembagaan petani yang berorientasi usaha tani kopi berbasis konservasi.

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.

Abstract

Tidal 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 splits 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 biofertilizer (1 kg) combined with NPK; 100% of standard dose (P2), 75% of the standard dose (P3), and 50% of the standard dosages  (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.
