Total Biomassa Pada Sistem Monokultur Kelapa Sawit (Elaeis Guineensis Jacq.) Dan Sistem Agroforestri Kelapa Sawit Dan Gaharu (Aquilaria Malaccensis Lamk.)

Riau is a province that has the largest palm oil plantations in Indonesia. The development of plantations, both corporate and smallholder plantations, still applies the monoculture system. The monoculture system for Palm Oil still has negative environmental impacts, one of which is reducing biomass productivity. In an effort to minimize these impacts, it is necessary to develop alternative palm oil plantations by implementing an Agroforestry system. One of the plants that can be developed is agarwood (Aquilaria malaccensis Lamk.) because it has semi-tolerant properties and is able to grow under the shade. The implementation of an agroforestry system has been carried out in the Tapung Kampar area by combining palm oil and agarwood but empirical data on biomass in this system are not available yet. The purpose of this study was to measure the biomass of palm oil and undergrowth on monoculture and agroforestry systems of palm oil and agarwood, to measure the biomass of agarwood in agroforestry system and to measure the total biomass in both systems. These studies were carried out on a community-owned palm oil plantation in Kemuning Village, Tapung Sub District, Kampar District, Riau. The study was conducted by survey method and plot determination using purposive sampling method. Sample plots totaling 6 plots at each cropping system with a plot size of 8 x 18 m. The observation sample points in each plot consisted of 5 palm oil per plot with a total of 30 samples per cropping system and 6 samples of agarwood in each plot in the agroforestry system with a total of 36 samples. Parameters observed in each plot were microclimate consisting of light intensity, temperature and humidity, thickness of top soil, estimation of biomass in agroforestry and monoculture systems consisting of estimation of total biomass of palm oil and agarwood with non-destructive methods using allometric equations with variable diameter and tree height. measurement of undergrowth biomass, measurement of palm fronds biomass and agarwood litter. Data analysis using t test with a level of 5%.
The results showed that palm oil biomass in agroforestry and monoculture systems was not significantly different with an average value of 52.11 tons/ha in agroforestry and an average value of 50.95 tons/ha in monoculture systems. The total biomass in the agroforestry system is greater than the total biomass in the monoculture system because of the addition of 10.43% of the biomass from agarwood in the agroforestry system.
