Abstract

Coffee plants need phosphorus nutrients for growth and fertilization in high quantities. Andisol has a very
low availability of P. Efforts that can be made to increase the availability of P are by utilizing phosphate
solvent microbes and coffee skin compost. The purpose of this study was to obtain the right type of microbial
phosphate solvent and organic coffee skin ingredients in increasing the availability and growth of coffee
plants in Andisol affected by the eruption of Mt. Sinabung. This study used a factorial randomized block
design (RBD) consisting of 3 replications. Factor I: (Microbial Phosphate Solvents) M0 = Without
application, M1 = Burkholderia cepacia, M2 = Talaromyces pinophilus, M3 = Burkholderia cepacia +
Talaromyces pinophilus. Factor II Organic ingredients of coffee skin compost are K0 = without organic
matter, K1 = 75 g, K2 = 150 g, K3 = 225 g. The results of the study showed that B.cepacia + T.Pinophilus
+ Mycorrhiza (M4) treatment can increase nutrient uptake of N, P and K of plants up to 12.3%, can increase
plant uptake of P up to 18.84%, increase uptake of plant K up to 19.53%. The treatment of 225g of coffee
husk compost (K3) can increase plant N nutrient uptake by 7.65%, plant P uptake to 26.11% and plant K
uptake up to 14.12%. M4K3 application can increase N uptake up to 53.28%, P uptake up to 98.56% and
increase K uptake of plants up to 56.45%. in general, the best treatment is M4K3.
