This research aims to 1) determine the amount of charcoal derived from the leaves of palm oil, the yield of palm oil to increase the productivity of palm oil per hectare 2) the amount of activated charcoal, bio increasing the percentage 3) Study. activated charcoal for biological growth, 4) to the basic use of charcoal derived from palm oil yield per hectare of palm oil. The experimental design was RCBD experiments with oil palm age 3 Resource Center. Kasetsart University Krabi conducted four series of experiments using chemical fertilizer 15-15-15 of 4.5 kg / tree / year. Equal and unequal amount of bio-char is 4.5: 0 (control), 4.5 5 4.5 10 4.5 15 kg / early
results showed. Palm oil is derived from the use of charcoal, oil palm volume of 15 kg per tree is appropriate to increase the yield of palm oil the most. The difference is statistically significant. The percentage of activated charcoal, bio-oil using 15 kg per tree as possible. Minor amounts of palm oil-based bio-charcoal 10 kg per tree. Did not differ significantly. But it is different from the treatment dose activated charcoal, bio-5 and 0 (control of Mugabe) kilograms per tree. And the growth of palm oil-based bio-charcoal consumption 15 kg per tree. The most promising in terms of growth, the height of the inflorescence addition, soil properties are better, too. The humidity level increases Ability to retain moisture well. Including the amount of nutrients in the soil. Followed by a series of experiments that put the charcoal, bio-10, 5, 0, respectively
, using charcoal derived from the leaves of palm oil, used as a soil additive. Because of charcoal derived from the leaves of palm oil provides a nutrient composition. This includes the carbon put into the soil, thus accumulating carbon into the soil. This is a process to reduce global warming. The bio battery at a higher rate to increase productivity per hectare palm oil.
