by Momon S Imanudin and Edi Armanto Abstract Reclamation of tidal lowland at South Sumatra had been conducted since 1961. Land productivity at this area so far had still varied. The success of rice production at level of 6 ton/ha at Delta Telang I area (A/B Type) was not followed by rice production at other areas. The field study was conducted at two land typologies consisting of wet land at Delta Telang I and dry land at Delta Saleh. Improvement of water management was done by drainage system for wet land type (Telang I) and water retention in combination with [...]

by Momon Sodik Imanudin, Robiyanto H Susando, and Bistok Simanjuntak The research objectives were to develop block emitter having S, Y, and Phi types suitable for high pressure condition in drip irrigations system and to test and compare the discharge for each type of emitter in the laboratory. Stages in this research were as follows: 1) designing block type of emitter; 2) developing of block structure media; 3) developing structure block; 4) installing and testing the emitter in the laboratory; and 5) Analyzing data. Results of laboratory test showed that the average discharge for each emitter Phi, S, and Y [...]

by Imanudin M.S, Armanto E, Susanto, R.H dan Bernas, S.M. Abstract. The research objective is to evaluate the water status in the tertiary block of tidal lowland for developing water management strategies and cropping pattern for food crop agriculture. The field study was conducted at reclaimed-tidal swamp areas having A typology (wet) located at Telang Karya Village, Primer 8, Delta Telang I. The method used was field action research. Corn was cultivated as a second crop indicator. For corn cultivation, the soil condition should be dry in which the water should be at the depth of 40-50 cm. The main [...]

by Momon Sodik Imanudin The general objective of this study was to develop operational strategy of water table control at reclaimed tidal lowland area for food crops cultivation. The used crop indicators were rice and corn. The study area is reclaimed tidal lowland areas at Delta Telang I Primer 8 as representative of land typology A and at Delta Saleh Primer 10 as representative of land typology C. The agro-hydrology monitoring was conducted at tertiary block 4 and 6 on Delta Saleh as well as tertiary block 2 and 5 on Delta Telang I. The concept of tidal lowland development [...]

by Lina Marlina, Momon Sodik Imanudin, and Satria J Priatna Since 1981 the tidal lowland of Telang II deltaic area had reclaimed. It is about 13.800 hectares of the areas has potentially for agriculture. Currently the area has high pressure to change the land use for food to estate crop. Therefore need to do research on the study of farming systems to see agricultural production in tidal lowland. Most of the land in the Delta Telang II planted with oil palm , rice and corn , especially in the village of Sukatani , Sukadamai Village and Village Mulyasari. The purpose [...]

by Momon Sodik Imanudin, Satria J Priatna, Elisa Wildayana, and M. Edi Armanto Agriculture and irrigation policies in the tidal wetlands are often too general, thus at the level of farm units they are often inaccurate in term of quality and quantity. The research purpose was to analyze the groundwater levels and to determine the effect of groundwater levels in relation to some soil chemical characters in tidal wetlands P17-5S Mulyasari village Delta Telang II Banyuasin.Indicators of potential land can be analyzed from parameters of variability of soil acidity, Al and Fe content, organic matter and phosphorus and nitrogen status [...]

A. Syarifudin, M. S. Imanudin, A. S. Moerwanto, M. Yazid, and F. X. Suryadi Canal erosion is one of the technical issues in tidal lowland agriculture. It is influenced by water flow in the canal under a designated water network system. This study aims at exploring several aspects related to the erosion at the secondary canal in tidal lowlands of Delta Telang I, Banyuasin District, South Sumatra. A survey was conducted to measure canal profiles related to water flow, observe grain size and sediment transport in secondary canal and its implication on the operation and maintenance of water infrastructures. Results [...]

Oleh: Prof. Dr. Ir. Robiyanto Hendro Susanto,. M. Agr. Sc. Abstrak Lahan rawa, baik yang tanah mineral ataupun gambut, berupa rawa pasang surut dan non-pasang surut (lebak) di Indonesia (33.3 juta ha) sebagian besar merupakan lahan konservasi dan kehutanan serta sebagian lainnya potensial untuk pengembangan pertanian (termasuk perikanan, perkebunan, peternakan, hutan tanaman, pemukiman). Optimalisasi lahan rawa untuk pengembangan pertanian yang sudah ada (4.0 juta ha) perlu dipelajari dengan seksama mengingat potensinya untuk mendukung kedaulatan dan ketahanan pangan Indonesia. Identifikasi dan karakterisasi lahan dan air secara rinci dan cermat digunakan untuk menentukan pola usaha tani yang akan dioptimalkan. Strategi perencanaan partisipatif [...]

Jos Houterman, Mestika Djoeachir, Robiyanto Hendro Susanto, Frank van Steenbergen, on Agriculture and Rural Development Working Paper 14 Indonesia, a nation of 17,000 islands, is well known for its diversity. There are sensitive differences between the densely populated inner islands (Sumatra, Kalimantan, Sulawesi, Irian Jaya, and many others). The inner islands monopolize much of the economic and institutional power in the country. They contain 70 percent of the population. Java, the main island, with 813 inhabitants per km², is among the most densely populated parts of the world. In contrast, the national population density average is 93 persons per km². [...]

oleh Robiyanto H. Susanto, Trisbani Arief, R.B. Pramono, dan M. Yazid Abstrak Lahan rawa baik yang berupa rawa pasang surut dan non-pasang surut (lebak) di Provinsi Jambi merupakan lahan potensial untuk pembangunan pertanian. Prospek lahan rawa lebak sebagai salah satu lahan potensial di Provinsi Jambi untuk pengembangan tanaman jagung perlu dipelajari. Identifikasi dan karakterisasi lahan lebak secara rinci dan cermat digunakan untuk menentukan: hidotopografi lahan, kesesuaian lahan, sasaran calon lokasi, luas areal, calon petani atau kelompok tani, peluang untuk peningkatan intensitas pertanaman, ketersediaan tenaga kerja, permasalahan dan kendala yang dihadapi dalam pengembangan-pengembangan tanaman jagung. Pengembangan tanaman jagung di lahan lebak [...]

oleh Robiyanto H. Susanto, A. Trisbani, M. Sapri, M. Yazid, dan R.B. Pramono Abstrak Pemanfaatan lahan rawa untuk pertanian tanaman pangan dan hortikultura di Sumatera Selatan memberikan kontribusi yang nyata terhadap total produksi padi Sumatera Selatan (2 juta ton pada tahun 2003) yang berasal dari rawa lebak (28,6%) dan rawa pasang surut (30%). Pemanfaatan lahan rawa pasang surut untuk pertanian tanaman pangan mempunyai masalah on-farm (penyiapan lahan, tenaga kerja, sarana produksi pertanian, tanah, tata air, dan hama penyakit tanaman), off-farm (panen, perontokan gabah, pengeringan, penyimpanan, pemasaran, dan harga), serta masalah-masalah kelembagaan, transportasi, penyuluhan, prasarana pendukung, dan permodalan. Selain untuk tanaman [...]

oleh Robiyanto Hendro Susanto Abstrak Alih fungsi lahan di Pulau Jawa, Bali dan Madura, dari penggunaan lahan untuk pertanian ke penggunaan non-pertanian (industri, pemukiman, sarana, prasarana, rekreasi) dapat mencapai 40.000 ha per tahun. Selain itu terjadi juga degradasi lahan, penurunan jumlah dan mutu air untuk kehidupan, disamping terjadinya banjir dan kekeringan. Hal-hal tersebut tentu saja akan mengancam ketahanan pangan nasional mengingat jumlah penduduk Indonesia yang terus meningkat. Pada sisi lain, di pulau Sumatera, Kalimantan, dan Irian Jaya dijumpai lahan rawa seluas 33.3 juta ha, yang merupakan lahan rawa konservasi, lahan suaka alam, dan sebagian kecil dikembangkan untuk transmigrasi, pemukiman, dan [...]
