PRIORITAS PENGEMBANGAN KOMODITAS TANAMAN PANGAN DI KABUPATEN ROTE NDAO PROVINSI NUSA TENGGARA TIMUR

Chris Natali Namah

 Abstrak. Agricultural development aims to increase production to strengthen food availability in order to meet the basic needs of the community in terms of quantity, quality and affordable prices, increase farmers' income by developing agribusiness-oriented farming systems. Food crops are strategic and attractive commodities in relation to the issue of increasing production and guaranteed availability. Food needs continue to increase in line with increasing population. Therefore it is necessary to research on the analysis of the development of food crop commodities using the Location Quotient (LQ) analysis and then to formulate a food crop development strategy that is owned by Rote Ndao District. This research was conducted in Rote Ndao Regency starting from March-October 2018. Data were collected in the form of secondary data and primary data. Data collected in the analysis using Location Quotion (LQ) analysis is then performed with a SWOT analysis to formulate a development strategy. Results obtained: Average food crop production can be explained that each district has a superior commodity (one district and one commodity) based on the highest LQ value, namely: lowland rice commodity in Lobalain sub-district, Paddy fields in Southwest Rote sub-district, Lobalain and Central Rote, Corn in the North West Rote sub-district, Peanuts in the North West Rote sub-district, Green beans in the North West Rote Sub-district and sweet potatoes in the North-West Rote sub-district. The priority strategies that can be carried out in the development of superior food commodities are optimizing agricultural land, diversification of farming in production activities and post-harvest processing activities to absorb available labor, cooperation between marketing of agricultural products, application of farmer selling price information systems, training in eradicating pests and diseases naturally, dealing with droughts and floods, providing online market systems.

POTENSI CRYOPRESERVASION BENIH KOPI ARABIKA: PENGARUH POTENSIAL OSMOTIK DAN DURASI OSMOCONDITIONING TERHADAP VIABILITAS DAN INDEKS VIGOR HIPOTETIK BENIH

 Abstrak. Cryopreservasion Potency of Coffea arabica Seed: Influence of Potential Osmotic and Osmoconditioning Duration to Viability and Hypothetic Vigor Index of Seed. This research aimed to prove the influence of potential osmotic and osmoconditioning to cure the seed viability and hypothetic vigor index of Coffea arabica as the result of draining or degradation of seed water until 12%. This research was an early step to test cryopreservasion potency of Coffea arabica seed, arranging factorially in Completely Randomized Design, consisting of two factors that are three potential osmotic levels (P): -0.5 Mpa; -1.0 MPa and -1.5 Mpa; and 3osmoconditioning duration level (D): 3, 5, and 7 days; and control (without osmoconditioning). Variables measured were electrical conductivity, free fat acid contents, radicel growth, time required for reaching 50% seed germination (T50), seed viability and hypothetic vigor index. Data obtained were analyzed using Analysis of Variance, and Duncan Multiple Range Test (DMRT) at 5%. The result indicated that potential osmotic -0.5 MPa of osmoconditioning performed best influence to T50. Potential osmotic of -1.5 MPa presented best effect to seed viability and hypothetic vigor index. Five days Osmoconditioning performed best influence to time T50. Potential osmotic -0.5 MPa of 3-days osmoconditioning presented best influence to free fat acid contents and seed viability. Potential osmotic -0.5 MPa of 5-days osmoconditioning performed best influence to free fat acid contents and radicel growth. Potential osmotic -1,0 MPa and 5-days osmoconditioning were best affected to seed viability; while, potential osmotic -1.5 MPa of 5-days osmoconditioning also performed best influence to seed viability, and potential osmotic -1.5 MPa of 7-days were significant to seed viability and electrical conductivity of Coffea arabica.Keywords: cryopreservasion, potential osmotic, osmoconditioning duration, Coffea arabica
