Abstract: Curcuma aeruginosa Roxb. or black ginger is widely distributed in Southeast Asia has a local name ginger erang ginger black is used as a traditional medicine because it contains bioactive compounds such as saponins, flavonoids, polyphenols, triterpenoids, and glucans (Sweetymol and Thomas, 2014; Kitamura et al., 2007). Black ginger rhizome is used for digging herbs and anti-rheumatic or inflammatory (Reanmongkol et al., 2006), skin diseases (Djauharia and Sufiani, 2007), cough and asthma (Nasrullah et al., 2010), anti-microbial (Angel et al., 2012), anti-fungal (Srivastava et al., 2006), and anti- oxidant (Nurcholis et al., 2015). The production and productivity of black ginger in Indonesia are still relatively low when compared to other leading biopharmaca commodities such as ginger. The purpose of this research activity is the use of liquid organic fertilizer on five accessions of black ginger will affect morphology and production as medicinal raw materials (BBOT). The research was conducted with a randomized group design (RAK) experiment with 2 factors. The first factor is liquid organic fertilizer and non-liquid organic fertilizer. The second factor of black ginger accession consists of 5 accessions, namely Yukum Jaya accession (TI.13), Bondowoso accession (TI.14), Ciamis accession (TI.15), Pangandaran accession (TI.16) and Pasuruan accession (TI.17) with 3 repetitions. The parameters observed were plant height, stem diameter and number of leaves. Morphological parameters observed include rhizome harvest weight is the weight of the rhizome measured at harvest, rhizome wet weight, fleshy root weight, number of rhizome propagules. All data were analyzed by analysis of variance and further test using Duncan test (P < 0.05). This study found that the use of LOB can increase production since the vegetative period for the formation of leaves and stems as well as for the development and growth of plants that can be seen in plant morphology in the results of accessions Yukum Jaya, Ciamis and Bondowoso. In addition, rhizome weight using LOB can reach 2,162.11 for Ciamisaccession.
