Analisis Interpretasi antara Kemiringan Lahan, Hujan dan Jumlah Tandan terhadap Produktivitas Kelapa Sawit (Elaeis Guineensis Jacq.) di Perkebunan Pabatu PT Perkebunan Nusantara IV Regional II

Abstract

This study aims to determine and analyze the effect of rainfall, rainy days, number of bunches, and land slope on the productivity of oil palm (Elaeis Guineensis Jacq.) in the Pabatu plantation of PT. Perkebunan Nusantara IV Regional II from August to October 2025. The hypothesis of this study is that there is a significant effect of rainfall, rainy days, number of bunches, and land slope on the productivity of oil palm (Elaeis Guineensis Jacq.) in the Pabatu plantation of PT. Perkebunan Nusantara IV Regional II. This study uses secondary data available at the plantation office administration, including data on fresh fruit bunch (FFB) production and number of bunches from 2015 to 2024, monthly rainfall and rainy days data from 2014 to 2023, and land slope data. The analysis methods used are multiple linear regression and correlation analysis. The feasibility test model with classical assumption tests included normality tests, heteroscedasticity tests, multicollinearity tests, and autocorrelation tests using SPSS v.25 for Windows statistical tools. The data were tested and analyzed based on land slope, namely flat land, moderate slope land, and steep slope land. The results of this study indicate that rainfall and rainy days have no significant effect on oil palm productivity in flat, moderately sloping, and sloping land in the Pabatu plantation. The number of bunches has a significant effect on increasing oil palm productivity in flat, moderately sloping, and sloping land in the Pabatu plantation. Rainfall, rainy days, and number of bunches simultaneously have a significant effect on oil palm productivity on flat land, moderately sloping land, and steeply sloping land in the Pabatu plantation. The correlation between rainfall, rainy days, and number of bunches varies from moderately weak to strong on productivity on flat land, moderately sloping land, and steeply sloping land in the Pabatu plantation.
