Helmanto H, Damayanti F, Purnomo DW. 2015. Effect of Bioposka compost in the seed germination process and growth of Quassia indica. Pros Sem Nas Masy Biodiv Indon 1: 852-855. Quassia indica (Gaertn.) Noot. is a member of Simaroubaceae family. This plant has many potentials as a medicinal and ornamental plant. Propagation of Quassia indica is seed germination. Bioposka is one type of compost produced by the Center for Plant Conservation Botanical Garden LIPI, Bogor. This study aimed to determine the effect of Bioposka on germination and seedling growth of Quassia indica. The research used standard media (sand) with the addition different number of Bioposka. The research method used a Completely Randomized Design (CRD). Seedling media used was sand, sand: Bioposka (1: 1) and Bioposka. Each media was made two replications, and each replication contained 10 unit of seeds. The parameters measured were the high number of seeds germinated and seedling growth for three months. Data analysis of viability (germination total, normal germination, germination first day, the last day of germination, germination rate coefficient, coefficient of simultaneity grow) and seedling growth used ANOVA with the STAR software. The results showed that the highest viability was the sand media: Bioposka with a total of 55%, while on Bioposka 35% and 30% sand. Analysis of variance of high growth, the media's treatment showed significant differences in test level 5%, in a further test DMRT, the highest growth occurred in sand medium with an average growth of 24.49 cm, sand: Bioposka 18.48 cm and Bioposka 16.22 cm.
