Abstract
This research has been conducted for 3 (three) months in April to June 2018. The research includes the maintenance of test animals and the manufacture of extracts that will be in the Basic Laboratory of Universitas Samudra. The method used in this study consisted of making coffee extracts, making combination of solvents and test activity of preparation. Hair length data and hair weight obtained were then processed statistically to see if there was a significant difference between the test area and the treatments. Normal and homogeneous data distribution is processed for the analysis of variance (ANOVA). The results showed that treatment 3 (0.113 cm day-1) on day 21 was faster than positive treatment (0.101 cm day-1), negative treatment (0.060 cm day-1), 4 treatment (0.099 cm day-1) and 5 (0.090 cm day-1) treatment. From the measurement of hair weight measured for 21 days showed treatment 3 resulted the largest hair weight of 0.207 g, followed by positive treatment 0.193 g, 4 treatment of 0.187 g, treatment 5 with 0.177 g and the lowest weight was in the treatment negative by 0.127 g.
