Abstract

Development of jamblang (Syzygium cumini) as medicinal plant currently constrained by the aspects of cultivation technology (vegetative propagation), so the provision of medicinal plants for the mass scale was very difficult. The objective of this research was to evaluate the effect of five doses of  growth regulator substance on growth of S. cumini’s shoot cuttings. The active ingredient composition of hormone/ Growth Regulator Substance (GRS) in this study were Naphthalene Acetic Acid (NAA) 3 percent and Naphthalene Acetamide (NAAm) 0.75percent. The experiment was arranged in Completely Random Design using 5 concentrations of growth regulator substance namely 0g.10ml-1(control), 2g.10 ml-1, 4g.10ml-1, 10g.10ml-1 and powder (not dissolved). The results of this experiment proved that  4g.10 ml-1of growth regulator substance produce the highest height growth (29.84 cm or 21.74 percent increment), the highest number of leaves (23.72 pieces or 4.63 percent increment), the heaviest dry weight of stem and leaves (3.36 gram or 43.59 percent increment) and the highest top-root ratio (6.55 or 10.08 percent increment). The highest survival percentage was resulted from GRS powder treatment (80 percent or 18.81 percent increment), but did not significantly different to GRS treatment of 4g.10 ml-1 (77.33 percent). The application of 4g.10 ml-1 is recommended to use to produce the better growth of cuttings planted on soil.

Abstract

Dried nampu leaves have become an export commodity as raw materials for the pharmaceutical, cosmetic, and herbal cigarette industries. However, the massive exploitation of nampu leaves in their natural habitat in forest areas has raised concerns that it could disrupt forest sustainability. Therefore, financial analysis is needed to find out whether this business could be expanded or not.  This study aims to examine the feasibility of processing nampu leaves into dried chopped leaves, the challenges and the prospects for its development. We conducted a case study on a nampu leaf processing business group in Cihaurbeuti Subdistrict, Ciamis, West Java. Data was collected through in-depth interviews and field observations. The results showed that the nampu leaf processing business was feasible because of the availability of resources, an easy process and a relatively short payback period as indicated by the R/C value of 1.17 and BEP production of 2,596.15 kg and BEP sales of IDR38,942,307 which can be achieved in less than 1 year. The challenges of this business are the availability of raw materials, marketing guarantees and forest sustainability. Government assistance is very important in supporting the sustainability of this business.
