Abstract

Arenga pinnata is a commodity that has high economic value, but hasn’t been utilized optimally. The population of Arenga pinnata is decreasing. This happens because forest encroachment and felling of Arenga pinnatatrees are not balanced with the regeneration of young plants. Based on the nature ofArenga pinnataand its utilization, it is recommended to plant in stages so that the availability of plants  is guaranteed.Cocopeat growing media is suitable for rehabilitation of critical land in dry climates. Cocopeat functions to keep plant roots from drying out and hydrated properly. The research was carried out using a Completely Randomized Design (CRD) consisting of 4 treatments with 5 replications in order to obtain 20 experimental units. Each replication consisting of 5 experimental samples, so that the total seedling used is 100 experimental units. This research used 4 treatments with cocopeat composition, P1 = 100% soil planting medium as control P2 = 75% soil planting medium + 25% cocopeat P3 = 50% soil planting medium + 50% cocopeat P4 = 25% soil planting medium + 75 cocopeat %. The data obtained from the results of the study were statistically analyzed using Analysis of Variance (ANOVA) and using Duncan's New Multiple Range Test (DNMRT) at the 5% level. Cocopeat growing media has a significant effect on leaf surface area. The composition of the best cocopeat growing media used for the growth of Arenga pinnata seedlings is a composition of 75% cocopeat + 25% soil, with 100%  percentage live of seedlings, an increase in seedling height of 10,08 cm, leaf surface area of 102 cm2.Keywords: Arenga pinnata, cocopeat, growth

Abstract

Shorea leprosula  is a Dipterocarpacean tribe that is very adaptive in open areas, both in submerged and dry peatlands. This is one of the triggering factors for cultivating Shorea leprosula plants in Riau, which are predominantly peatlands. Superior plants of Shorea leprosula need to use fertilizers as a medium to improve plant quality. One of them is cow urine waste that can be used at an affordable price and is easily available and has a function as a plant pest control. This study aims to determine the response of the growth of Shorea leprosula to the application of liquid cow urine fertilizer under the shade of oil palm stands. This study used a completely randomized design (CRD), which consisted of 4 (four) treatments, with four replications in order to obtain sixteen experimental units. Each experimental unit consisted of five Shorea leprosula seedlings, with a total number of 80 seedlings. The treatment carried out was administration of cow urine. The results showed that the dose of liquid cow urine fertilizer had an effect on the growth of Shorea leprosula sedlings in the treatment of 20% cow urine liquit fertilizer (K1) by showing the percentage of 100% life yield, and the increase in seed height of 6,86 cm.Keywords : Shorea leprosula, cow urine, peat
