Abstract :
The study was a test of density, viscosity and surface tension on the ink print with the basic ingredients of coconut husk charcoal. With the aim to determine the comparative value of the density, viscosity and surface tension of ink made from charcoal with commercial ink canon. Measurement of the density value is done by comparison of mass per volume of ink, while to know the value of ink viscosity using Ostwald viscometer and surface tension measurements using capillary rise. Based on the research that has been conducted shows that the ink charcoal has a value of density, viscosity and surface tension greater than the commercial inks. Ink density value of charcoal ink made from charcoal has an average density of 0.91 gr/cm 3 greater 4.5% of the komersial.Nilai ink viscosity ink made from charcoal has an average viscosity of 2,422 poise higher 93.2% of the surface tension komersial.Nilai ink ink made from charcoal has a surface tension value of the average is 34.584 dyne/cm greater 15.7% of the commercial ink.
