The purpose of this research is to determine the effect of natural Plant Growth Regulator (PGR) (old coconut water, young coconut water and shallot extract) and obtain the best concentration of PGR for Tin plant cuttings. The study was carried out by field trial methods arranged in Completely Randomized Design (CRD) with a single factor trial design. The treatments tested were : the addition of PGR from natural ingredients, namely: old coconut water 20% and 30%, young coconut water 20% and 30%, red onion extract 60% and 70% and commercial PGR (Root Up). Each treatment were repeated 3 times. The results of this search showed that all natural PGR tested, namely from young coconut water concentrations of 20% and 30%, old coconut concentrations of 20% and 30% and shallots concentrations of 60% and 70% can be used to increase the growth of Tin plant cuttings.
