Abstract

This study aims to analyze the income of oil palm farming businesses in Kogem Village, Marbau District, Labuhanbatu Regency, consisting of production costs, revenue, income, and the revenue-to-cost ratio in oil palm farming. The sampling method used in this study was purposive sampling. This study collected data using primary and secondary data. Data analysis was conducted to calculate costs, revenue, income, and the R/C ratio. The results showed that the R/C ratio for oil palm farming was 3.48, meaning that every Rp. 100.00 additional costs incurred by the entrepreneur will generate Rp. 3.48.00 in revenue. This value is greater than 1, making palm oil farming economically profitable.

Abstract

This study aimed to determine the effect of fertilizer application with a concentration of 5 grams per liter on the vegetative growth of immature oil palm plants (TBM). The study was conducted for 4 weeks with observation intervals once a week, using two treatments: control and application of 5 grams per liter fertilizer, each with 10 replications. Observed parameters included plant height, number of leaves, stem diameter, and leaf length. Data were analyzed using ANOVA test and continued with DMRT test at the 5% level. The results showed that the application of 5 grams per liter fertilizer had a significantly different effect on all growth parameters compared to the control in each observation week. This treatment consistently resulted in higher growth, so it can be concluded that the application of 5 grams per liter fertilizer is effective in increasing the vegetative growth of immature oil palm plants.
