The effect of blade density variation to cocopeat mass that produce by Poltesa cocopeat machine

Cocopeat machines that have been developed today, were carried out with variations in the speed of rotation, blade length, shape, and treatment objects (coconut coir immersion). There has no development a cocopeat machine focuses on density. It is suspected density affects to difference mass produced. This study was true experiment. The dependent variable mass. independent variables density, consisting σ1 (84/210π), σ2 (42/210π) σ3 (21/210π). For each variation conducted 10 experiments. sample 30 pieces coconut coir. 50 grams. engine's spin speed, length are same for all samples. data analyzed using t test at significance level 5%. average values ( = 16.5430; S1 1.9674), 12.2650; S2 1.8341) (μ3 10.0988; SD 1.8943). showed value between groups to12 5,030; to23 2,598; to13 7,462.
