Abstract

This study aims to analyze the correlation between the area of oil palm plantations and oil palm production in Indonesia, especially in the Sumatra and Kalimantan regions which are the centers of oil palm plantation distribution. Data collection using secondary data from the Central Statistics Agency (BPS), this study aims to determine the relationship between the increase in land area and oil palm plantation production over the past 10 years. This study uses a quantitative method with a correlative approach. Data analysis was carried out using a bivariate correlation Pearson correlation test to determine the positive relationship between plantation area and oil palm production. The results of the analysis showed a significant positive relationship between the land area variable and oil palm production in both the Sumatra and Kalimantan regions, this is indicated by a positive number and a strong correlation of 0.852 for the Sumatra region and very strong, namely 0.996 for the Kalimantan region. In addition, the results of the interpretation of the correlation by looking at Sig. (2-tailed) also show that between the land area variable and production there is a significant correlation, namely 0.002 for the Sumatra region and a value of 0.000 for the Kalimantan region. Although the correlation between land area and production shows a positive value and has a very strong correlation, there are still other factors such as technology, climate, and management practices that also play a role in influencing palm oil production results.

Abstract

The frond base supports the oil palm tree trunk and distributes photosynthesis results. Frond base fracture (sengkleh) is thought to reduce plant growth performance and production. This study aims to quantitatively analyze the effect of frond base facture on vegetative and reproductive growth of oil palm. The study was conducted for three months at the KUD Sumber Sawit Makmur oil palm plantation, Central Kalimantan, Indonesia. The method used was an agronomic survey with observations on six plant blocks: three blocks with healthy trees and three with unhealthy trees (there were more than three sengkleh fronds). Three plant samples were observed in each block. The parameters observed included the number of frond bases facture, new frond growth, number of female flowers, number of bunches harvested, and average bunch weight. Data were analyzed using two-factor ANOVA and continued with a 5% DMRT test if there was a significant difference. The results showed that frond base conditions had a very significant effect on all observation parameters. Plants with normal frond bases showed faster new leaf sheath growth, more female flowers, and higher yields than plants with fractured frond bases. These findings confirm that frond bases can be used as important visual indicators in technical decision making in the field.
