Palm empty fruit bunches are palm oil mill waste that has the potential to be used as a source of compost raw material. However the composting process is quite long due to the presence of lignin content so that required additional bioactivator. The purpose of this study was to identify the effect of palm empty fruit bunches characteristics decomposed by symbiont bacteria of larvae Oryctes rhinoceros Linn to growth of oil palm seedlings in pre nursery. The study was conducted in the greenhouse of Plant Seedling and Plant Protection Center Medan Indonesia and the propagation of horn beetle larvae symbiont bacteria at the Disease Laboratory of the Faculty of Agriculture Universitas Sumatera Utara Medan Indonesia in January-May 2021. The study used a factorial randomized block design (RBD) with 2 treatment factor and 3 replications. The first factor is the type of activator bacteria consisting of 7 levels namely without activator bacteria Bacillus stratosphericus 50 ml/kg Bacillus stratosphericus 75 ml/kg Bacillus stratosphericus 100 ml/kg Bacillus siamensis 50 ml/kg Bacillus siamensis 75 ml/kg kg and Bacillus siamensis 100 ml/kg. The second factor is the decomposition time consisting of 2 levels namely 5 weeks and 7 weeks. The results showed that the treatment of bacteria activator type and decomposition time had a significant effect on the quality of the compost namely pH water content C/N ratio and nutrient content. The interaction of B. siamensis 50 ml/kg palm empty fruit bunches with a decomposition time of 5 weeks resulted in the best growth of oil palm seedlings in pre nursery.

Abstract

Palm empty fruit bunches are palm oil mill waste that has the potential to be used as a source of compost raw material. However the composting process is quite long due to the presence of lignin content so that required additional bioactivator. The purpose of this study was to identify the effect of palm empty fruit bunches characteristics decomposed by symbiont bacteria of larvae Oryctes rhinoceros Linn to growth of oil palm seedlings in pre nursery. The study was conducted in the greenhouse of Plant Seedling and Plant Protection Center Medan Indonesia and the propagation of horn beetle larvae symbiont bacteria at the Disease Laboratory of the Faculty of Agriculture Universitas Sumatera Utara Medan Indonesia in January-May 2021. The study used a factorial randomized block design (RBD) with 2 treatment factor and 3 replications. The first factor is the type of activator bacteria consisting of 7 levels namely without activator bacteria Bacillus stratosphericus 50 ml/kg Bacillus stratosphericus 75 ml/kg Bacillus stratosphericus 100 ml/kg Bacillus siamensis 50 ml/kg Bacillus siamensis 75 ml/kg kg and Bacillus siamensis 100 ml/kg. The second factor is the decomposition time consisting of 2 levels namely 5 weeks and 7 weeks. The results showed that the treatment of bacteria activator type and decomposition time had a significant effect on the quality of the compost namely pH water content C/N ratio and nutrient content. The interaction of B. siamensis 50 ml/kg palm empty fruit bunches with a decomposition time of 5 weeks resulted in the best growth of oil palm seedlings in pre nursery.
