3.2. The Probability of Farmer to Use Organic Fertilizer
The influence of these variables with the opportunities of farmers using organic fertilizers assessed by testing the equation logit, who was twice the value of Nagelkerke R

statistic is equal to 0459, thus it can be concluded that the ability of independent variables to explain the model is at 45.9 percent or statistical values
of log-likelihood 91 365. Table 2. Logit model coefficients opportunities rice farmers use organic fertilizers in the district Banyuasin

Value - the value of such statistics are presented in Table 3 shows the logistic regression coefficient Logit, Wald, and significance tests for each variable according to the original allegation a priori. The
effect of each of these variables on the chances of farmers using organic fertilizers are described below.

86 Experience significant effect on the level of 1 percent. Age coefficient indicates that when other
variables are assumed constant ceteris paribus more opportunities young inexperienced farmers use organic fertilizers 0.07 times higher than the farmers have not experienced or otherwise inexperienced farmers use
organic fertilizers 0.07 times lower rate of use of organic fertilizers compared to more experienced farmers.
Extensive wetland will reduce the chances of getting farmers to use organic fertilizer by 1.28 times higher than farmers with an area of wetland is relatively narrow. The average land area of 1.64 acres of
paddy farmers, where farmer organic fertilizer user average area of only 1.4 hectares lower. For farmers producing organic fertilizer independently with the materials available in the surrounding rice fields such as
straw, and manure and decomposing organisms then it takes more manpower that need workers in larger numbers. The average family size rice farmers 4. Shortage of labor in the family farmers met through labor
outside the family with a certain wage level. With the high level of labor costs is IDR.65.000
–IDR.70.000 per day.
Opportunities of organic fertilizer use by farmers become larger with the decrease in fertilizer prices. Increase the odds of 0.07 times higher than when fertilizer prices experienced price declines. Instead farmers
use organic fertilizers chance is even greater for rice price high. Pure rice farmers using organic fertilizer is relatively small 6.32 percent , the biggest part of rice farmers using organic and inorganic fertilizers together
as much as 46.32 percent , and farmers use inorganic fertilizers such as urea and pure SP -36 47.37 percent. Effective use of organic and inorganic fertilizers simultaneously deliver higher production compared to the
use of organic fertilizer or inorganic fertilizer alone.
Improve educational opportunities for farmers to use organic fertilizers 0.18 times higher with the higher education rice farmers. Average rice farmer education studying for 8 years or equivalent secondary
school. Pure organic farmers fertilizer users have higher education for 10 years or the equivalent of high school. Organic fertilizer application requires specific knowledge of fertilizer production process, the process
of mixing different types of organic fertilizers and so on. Farmers require additional education or training.
Market access has a positive effect on increasing the chances of farmers using organic fertilizer. It means that the availability of ready-made organic fertilizer or material - material for organic fertilizer such as
microorganisms on the market or stall - stall or stall - stall of agricultural inputs that are close to production centers encourage increased use of organic fertilizers by rice farmers. Market access will increase probability
of farmers use organic fertilizers by 0.93 times higher when a more open market access.
