The second, source of household income for farmers is obtained from oil palm farming, non-oil palm farming and non-farming activities with an average total household income of the oil palm farmers of IDR 46,363,655 per year. The first results showed that oil palm is very profitable with an average income of IDR 30,666,620 per hectare per year. This study conducted at one of oil palm location center in Central Mamuju Regency, West Sulawesi by using questionnaires. Sampling for respondent in this study was carried by simple random sampling to the oil palm farmers in the study location. The purpose of this study was to determine oil palm, to calculate contribution of non-oil palm and non-farming household and contribution of oil palm plantations to farmers' income. This research was conducted in West Sulawesi, Indonesia on June to September 2020. The interaction between the two treatments had no significant effect on all observed variables.Oil palm is an industrial plantation that is useful as a producer of cooking oil, industrial oil, and fuel. NPK significantly affected plant height, leaf length, leaf width, and leaf area, but no significant effect on stems diameter and number of leaves. The results showed that Mabar Fine Compost significantly affected plant height, leaf length, leaf width and leaf area, but had no significant effect on stem diameter and number of leaves. The second factor is dosage of NPK fertilizer: N 0 = 0 g/plant, N 1 = 3 g/plant, N 2 = 6 g/plant, and N 3 = 9 g/plant.
The first factor is dosage of Mabar Fine Compost fertilizer: M 0 = 0 g/polybag, M 1 = 150 g/polybag and M 2 = 300 g/polybag. The study used a Randomized Block Design (RBD) consisting of two factors. Pardede at a height of ± 23 m above sea level. This reseach aims at determining the effect of Mabar Fine Compost fertilizer and NPK fertilizer on the growth of oil palm seedlings in Pre Nursery, that was conducted from May to August 2019 in the experimental garden of the Faculty of Agriculture, Darma Agung University on Jln.
