Proceeding of 2013 International Seminar on Climate Change and Food Security ISCCFS 2013 Palembang, South Sumatra -Indonesia, 24-25 October,2013 88 received by farmers is small Saragih, 2001. How was the technical and economic efficiency of tall variety in small holder plantation in the various typologies tidal land South Sumatera?

2. Methodology

This zoning study was purposive sampling, because it is one of the largest oil producing regions and the people managing the largest coconut plantation in South Sumatra province. The research method used was a survey Saptawan, 2000; Sriati, 2004 and data obtained from samples sourced to represent the population Mantra, 1998 in Yamin, 2003. Locations sampled Banyuasin regency, Sungsang district of the Sungai Semut village, and Makarti Jaya of the Pendowo Harjo village type A, Muara Telang district of the Sumber Jaya and Marga Rahayu village type B , OKI regency, Air Sugihan district of the Mukti Jaya and Srijaya Baru village type C , then of the Kerta Mukti and Banyu Biru village type D. Considering that the majority of the villagers are subsistence farmers of tall variety in a tidal land that is always wet type both large and small at high tide. Withdrawal sample farmers was conducted using stratified random balanced proportionate stratified random sampling Bungin, 2010 with the sample to be studied samples totaling 240 farmers 10 per cent of the total population in the coconut farmers. Analysis tool used was the Cobb Douglas production function model Debertin, 1996, whereas the results of the regression testing of the production unction included statistical test t-test,f-test, the coefficient of determination and the classical assumption test multicollinearity test, heteroscedasticity test, autocorrelation test. The efficiency of priceallocative efficiency in coconut farming in a comparison of the value of the marginal product NPM and input prices Px Soekartawie, 2003. The test of the efficiency of priceused NPM Xi H Xi with hypothesis formulation as follows : � � = � � . = � � . � � . = � Ho was NPM Xi H Xi = 1 Hi was NPM Xi H Xi ≠ 1 When NPMXiHXi=1, then Ho was accepted which means that the coconut farming reached the priceefficiency. When NPMXiHXi≠1, then Hi was accepted which means that there were two possibilities in coconut farming namely it had not reach the the efficiency of priceyet if NPM Xi H Xi 1, or did not achieve the efficiency of priceif NPM Xi H Xi 1.
