Analisis Interpretasi Antara Hujan, Jumlah Tandan dan Kemiringan Lahan terhadap Produktivitas Tanaman Kelapa Sawit (Elaeis guineensis Jacq.) di Kebun Huta Padang PT. Perkebunan Nusantara IV Regional 1

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 plants (Elaeis guineensis Jacq.) in the Huta Padang plantation of PT. Perkebunan Nusantara IV Regional 1 from February to March 2025. The hypothesis of this study is that there is a real effect of rainfall, rainy days, number of bunches and land slope on the productivity of oil palm plants (Elaeis guineensis Jacq.) in the Huta Padang plantation of PT. Perkebunan Nusantara IV Regional 1. This study uses secondary data available at the plantation office administration and the board of directors, including data on FFB production and number of bunches from 2015 to 2024, monthly rainfall and rainy days data from 2014 to 2023 and land slope data in the form of digital elevation model (DEM) data obtained from a lidar sensor drone owned by PT Perkebunan Nusantara IV Regional 1 which was processed using the QGIS mapping software tool. The analysis method used is multiple linear regression analysis and correlation. The model is tested for its feasibility with the classical assumption test including the normality test, heteroscedasticity test, multicollinearity test, and autocorrelation test using the SPSS.v.25 for windows statistical tool. The data is tested and analyzed based on the slope of the land, namely flat, medium and high slopes. The results of this study indicate that rainfall and rainy days have no significant effect on oil palm productivity on flat, medium and high slopes in the Huta Padang plantation. The number of bunches has a significant effect on increasing oil palm productivity on flat, medium and high slopes in the Huta Padang plantation. Rainfall, rainy days, and the number of bunches simultaneously have a significant effect on oil palm productivity on flat, medium and high slopes in the Huta Padang plantation. The correlation of rainfall, rainy days, and the number of bunches has a strong influence on oil palm productivity on flat, medium and high slopes in the Huta Padang plantation.
