Abstract:
Aren (Arenga pinnata Merr.) is one of the plants that has many benefits. The fruits can be taken for foodstuff and beverages, It can also produce sap, and the continuation process of making sap water can be processed into sweeteners (sugar). The growth of Aren determines the success of the plot development (as pilot plant). Manipulation of plant growth is necessary, this study aims to determine the effect of fertilization and mulching which has been given on the plant growth. This study has been done towards the treated sample with the dose of bioorganic liquid fertilizer as about 4 levels (0, 100, 150 and 200 ml/l of water) The treatment was repeated each 10 times that amount to 40 experimental units. The used analysis was completely randomized design (RAL) and advanced test if the treatment give an effect to te experimental units.The results of this Research shows that the treatment gives real effect on each experimental unit in terms of the increase of leaves and discoloration on the leaf color chart observations, The indication is showed by Annova testing. The ability of growing crops of Aren until the end of this study is still excellent 100%. The improvement of midrib leaves range from 2-3 midrib, while the size of the leaf color changes based on the levels of certain nutrients (N) is shown by the leaf color chart is close to number 4. Further tests shows that the effective dose that should be given is 100 ml/l of water because the result is not significantly different with other higher doses.
