PENGARUH HUJAN TERHADAP PRODUKSI TANAMAN KELAPA SAWIT DI PT. PERKEBUNAN NUSANTARA V KEBUN TANDUN
Abstract: Water availability
is a major factor limiting the production rate of oil palm plantations.
Availability of water for palm oil plants in the field is obtained from
rainfall. The research was conducted at PT. Perkebunan Nusantara V Tandun
Estate, Riau Province, for three months starting in June until August 2016.
This study uses secondary data available on the administration of the garden.
Secondary data for analysis include TBS monthly production data for 5 years
(2011-2015), the data age of the plant 5, 10 and 20 years after planting,
rainfall data and rainy day for 9 years (2007-2009). The analytical method used
is analasis multiple linear regression and correlation models tested for
feasibility with the classical assumption test including normality test, heteroscedasticity
test and multicollinearity test. Regression analysis showed that variable
rainfall and rainy days significantly affected on alpha 1% (Sig <α 0,01) to
FFB production at the age of 5 years. Results F-count of 29.07 with a
significance value of 0.00. The coefficient of determination (R2) obtained
63.8%. This means that 63.8% of FFB production variations can be explained by
the variation of the variables used and the remaining 36,2% is explained by the
other variables not incorporated into the model. Regression analysis equation
on a 5-year-old plant was Y = 414633.827 + 2530.523 X1 - X2 21848,726. Results
of correlation analysis at 5 years old plants showed variable rainfall and
rainy days have a very strong relationship. Correlation value of rainfall and
rainy days and 0.720 - 0.543.
