Abstract

Palm oil can produce high productivity which must be supported from several aspects, one of  them is a good and correct nursery. Palm oil nursery isusually carried out conventionally, namely planting using soil media. Hydroponic research using cocopeat and rice husks planting media on the growth of palm oil seeds in pre nursery has never been carried out. The objective of this study was to determine the growth of palm oil seedlings using the hydroponic method. This research was conducted in the STIPAP Medan greenhouse. This research was conducted from April to July 2018. This research was a non-factorial RAK, which consisted of four treatments, namely M0 (top soil), M1 (Cocopeat), M2 (rice husks), M3 (combination). Height, stem, number of leaves, dry and wet weight of roots and plants, root length were observed. Then data analysis with ANOVA with the continued test of 5% Duncan was performed. The results of the effect of cocopeat and rice husk media was there was no a significant effect on the treatment parameters of seed height, number of leaves, dry and wet weight of roots and plants, and root length.

Abstract

The expansion of oil palm plantations has led to debate over the negative impacts on soil fertility, hydrology, biodiversity and global warming. Climate change occurs due to changes in the composition of the atmosphere, mainly due to an increase in the concentration of greenhouse gases (GHGs). The usefulness of photosynthesis using CO2 is important to note. The purpose of this study is to measure / estimate the stored carbon absorbed by the 13-year-old Socfindo palm oil plant in the land suitability class S3. The study was conducted in May to June 2019 at PT Aek Torop Kebun III. Using descriptive design with Destructive and Non-Destructive methods based on ICRAF. The parameters are Above Surface Biomass (BAP) and Substance Biomass (BTB). The results showed that the oil palm surface surface biomass (BAP) at the age of 13 years was 117,855 tons / ha. The results of observations of Undergrowth Biomass (BTB) are 0.392 Ton / ha, the potential carbon stored is 54.394 Ton C / Ha and carbon dioxide absorption is 199.625 Ton CO2 / Ha.
