Abstract

Shorealeprosula included major timber producing tree and widely used include the use of such, plywood, sawn timber, and buildings of contruction.Shorealeprosulaproductiondecreasedamount, becausemost of the production comes fromnatural forests. The cultivation needed so shorealeprosula not become extinct, for it is important in the provision of quality seedlings. Shorealeprosula includedsemi tolerant types that require low light intensity for early growth. The nursery needed microclimate modification that environment conditionaccording to the requirement growing seedlings shorealeprosula.Alternativemade is bygivingshadeinthe nurseryShorealeprosula. This research aimstodetermine the effect ofshadeon the successandthe intensity ofthe shadeis best, on the growth ofseedlingsShorealeprosula the medium topsoil and compost mixture ratio 1:1.This research uses a completely randomize design method which consist of 5 treatments, 3 replications, and 5 units of the plant as a research unit.P0 = Without giving shade; P1 = the provision of shade level of 45%; P2 = the provision of shade level of 60%; P3 = the provision of shade level of 90%. The result indicates that treatment giving shade level of 90% is the best treatment on the parameters of observation, the high increasing (2,24 cm), the diameter increasing (1,2 mm) for seedlings Shorealeprosula in medium topsoil and compost mixture ratio 1:1.

Abstract

This research is aimed to know the characteristic of essential oil produced from distillation process of pucuk merah leaves. The young leaves and old leaves of pucuk merah was distilled using distillation clevenger type. Then, it is done an observation of essential oil yield, the essential oil colour, essential oil scent and solubility in ethanol. The results showed that the yield of pucuk merah young leaves essential oil is much more than the pucuk merah old leaves essential oil which are each respectively 0,18% and 0,118%. The colour of essential oil from pucuk merah young leaves and old leaves pucuk merah is yellow. Then, the essential oil from pucuk merah leaves is soluble in ethanol PA at ratio 1:1. Furthermore, through panelists assessment it’s known the essential oil of young leaves has distinctive scent of pucuk merah than the essential oil of  pucuk merah old leaves. As 65% panelists said that the essential oil from pucuk merah young leaves has distinctive scent of pucuk merah, while the others 35% said that it doesn’t have.  For the  essential oil from the old leaves,  as 50% panelists said that the essential oil from pucuk merah old leaves has the distinctive scent of pucuk merah, while the others 50% panelists said that it doesn’t have.  Keywords: Pucuk merah, Syzygium campanulatum Korth., Essential oil

Abstract

The purpose of this research was to determine the effect of compost fertilizer of oil palm empty bunch are mixed with top soil as a growing medium to promote growth and development of gaharu. This research is completely randomized experimental design (CRD), which consists of 4 treatment and 10 replicates, number of plants was 40. he treatments are: A0 = Without TKKS Compost, A1 = 25% TKKS Compost + 75% top soil, A2 = 50% TKKS Compost + 50% top soil, A3 = 75% TKKS Compost + 25% top soil. Based on the results of this research can be concluded that fertilization with compost of oil  palm empty bunch are mixed with top soil as a growing medium for seedlings of gaharu able to provide a complete nutrient, so the growth and development of gaharu for the better. The Treatment fertilizing with compost Tankos 75% were mixed with 25% top soil is a treatment that is able to give effect to the high growth of seedlings of gaharu which amounted to 5.08 cm, diameter growth of seedlings of gaharu which is equal to 0.15 mm and dry weight of the plant which amounted to 2.03 g. Keywords: Compost Tankos, Top Soil, Seeds of Gaharu
