FAKTOR-FAKTOR PENENTU EFISIENSI TEKNIS USAHATANI JAGUNG LAHAN KERING: STUDI KASUS DI KABUPATEN KUPANG PROVINSI NUSA TENGGARA TIMUR, INDONESIA
The research has been conducted in Kupang District of Nusa Tenggara Timur Province, focusing of maize dryland farming of small holders. Main problem of maize dryland farming is low productivity and high inefficiency. Objectives of the research are to know small holders maize farming income, factors influence production and technical efficiency of maize dryland farming systems. Questioner survey method was used to collect data. Thecnical Efficiency Effect model of translog production function were used to analyzed data. Results showed that, firstly, farmer’s maize income per ha is low (19,01%) compared to its potential income. Secondly, maize farming production system is mostly efficient that is 74% of total farms. Factors that important to influence maize productivity efficiently are land, seed, labour, and interaction between those factors. Thirdly,factors as sources of maize production inefficiency are farming experience and number of family members. Improving productivity and technical efficiency of small dryland maize farming should be focused on the two last factors in order to enhance famers food security during the year.
