From trial 1 found that coal from mangosteen, effective absorption of stain best.Two trials found that charcoal from wood waste remaining fruit Peel that sodium chloride stimulation is effective in absorbing the stain best. Mangosteen charcoal from the best.Three trials found that from the charcoal from the mangosteen, durian, bark, mixed with charcoal from the powerful best. Yes, coal is found again each type better.4 trial found that charcoal from wood waste remaining fruit Peel that sodium chloride stimulation by means of a powerful vibrator is better than soaking in a leave.5 trial found that charcoal from wood waste remaining fruit Peel with sodium chloride by stimulating different temperatures. No impact experiment Six trial discovered that charcoal from the mangosteen have workflow better than wood charcoal.Summary of results 1. the coal from the mangosteen is effective in absorbing the iodine solution colour best.2. the charcoal from the fruit Peel with sodium chloride is effective in absorbing. The dye methyl violet best. 3. the coal from shell of durian, mangosteen, mixed with effective in absorbing the dye methyl violet best. But not as good as with the use of charcoal from the bark of fruit each. 4. efficiency in absorbing the dye methyl violet way, shaking better than soaking in a leave.5. temperature to absorb the dye methyl violet different. Effective in absorbing the dye methyl violet no different.6. coal from mangosteen, effective absorption of methyl violet dyes better than wood charcoal powder.Suggestions.1. should study other natural materials that can be used in the development of a. Charcoal absorbs the stain. 2. should study ways to eliminate the remaining coal from absorption of the stain to non-polluting. Impact on the environment.
