| Summary: | The coconut plantation in Nort Sulawesi reachs 273.194 ha dan 42,72% of
the population depend on the coconut farm. Climate is an environmental factor
that affects the coconut production and impacts on the coconut farmer�s income
and levels of household food security of the coconut farmers. The purpose of this
study is to know : 1) the impact of climate change on the production of coconut
crops in Nort Sulawesi Province, 2) factors that affect the productivity of coconut
farm, 3) factors that affect the level of technical efficiency, 4) factors that affects
the coconut farm income, and 5) a level of household food security of coconut
farmers, and factors that influence.
The research was conducted in Province of North Sulawesi covering
North Minahasa Regency, South Minahasa Regency and Bolaang Mongondouw
Regency. Collecting simple random samples as much 50 households in each
regency, so the total of samples in three regency is 150 households of coconut
farmers. The analysis using the Ordinary Least Square Method (OLS) and a
method of estimation of stochastic frontier model that was done through 2 steps,
those are OLS model for estimate parameters of technology and production input
by using Maximum Likelihood Estimation Method (MLE).
Result of the research shows that the coconut production in North
Sulawesi Province was influence by variables of amount of climate rainfall as
much as 0,19% and the average of air temperature as much as 2,80%. The
average value of technical efficiency level as much as 0,85%, allocative
efficiency as much as 0,85%, and economic efficiency 0,72%. This indicates that
the coconut farmers have managed their farming efficiently. Variables that
influence the incresing of coconut production are a width of land, supply of
labours, plant population and types of coconut seeds. Factor of the plant age
decreases the coconut production 0,10%, and perception to the climat influence
negatively to the coconut production. The coconut farming income increase
significantly by increasing amount of wide area, plant population, pattern of
planting, but decreasing by increasing of labour wage, cost of pesticide, cost of
transportation, land status, and perception to climate. The level of food security
of household of coconut farmers classified on food secure (44%), however it is
still found food insecure households (8,67%). The household food security of
coconut farmers increase by increasing of the coconut farmer�s income and others
incomes, but the level decreases by increasing prices of rice, fish, eggs,
vegetables, cooking oil, and electricity cost. The analysis result of climate change
towards the production, income and food security shows that climate has a
negative and significant impact on the production and farming revenues, but to
the level of household food security of coconut farmers shows a negative and
unreal influence
