Judul: Aklimatisasi Kaempferia parviflora Wall. Ex. Baker pada Beberapa Komposisi Media Tanam dan Konsentrasi Paclobutrazol
Abstrak: Kaempferia parviflora is a medicinal plant which is highly valuable because of the bioactive compound in its rhizome, such as methoxyflavone. Conventional propagation of K. parviflora by splitting the rhizomes takes time because of long growing period prior to harvest and long period of rhizomes dormancy. Thus, rapid multiplication using in vitro culture is needed. The objective of this study was to obtain the optimum growing medium composition and paclobutrazol concentration suitable for K. parviflora acclimatization. This study was conducted from April to October 2013 and was arranged in a randomized completely block design with two factors and three replications. The first factor was growing medium composition (v/v) consisted of five levels i.e. 100% compost, 100 % charcoal husk, compost : charcoal husk = (1:1), compost : charcoal husk = (1:2), compost : charcoal husk = (2:1). The second factor was paclobutrazol concentration consisted of five levels i.e. 0, 1, 5, 10 and 15 ppm. The results showed that application of paclobutrazol at concentration up to 15 ppm had no significant effect on plant growth until 10 weeks after treatment (WAT). In contrast, growing medium composition significantly affected plant height, leaf length, leaf width, and leaf color. Plant growth on medium containing compost showed better growth than those grown in 100% charcoal husk medium.

Abstrak: Kaempferia parviflora (Zingiberaceae family) has a potency to be developed for a new medicinal plants in Indonesia. One of problems in its cultivation is the lack of planting material availability due to the long dormant period. The objectives of this research were to study the effect of various concentrations of BAP and ethephon, and also the effect of the prior growing condition to the dormancy breaking and shoot growth of K. parviflora rhizome. Two separate experiments were applied for two lots of rhizomes namely Cikabayan and Pasir Sarongge lots. Each experiment was arranged in completely random design with 2 factors. Experiment-1 used 4 concentrations of BAP (0, 50, 100, and 150 ppm) as the first factor. While, experiment-2 used 5 concentrations of ethephon (0, 200, 400, 600 and 800 ppm) as the first factor. The second factor in both experiments were prior shade condition at 55% artificial shading and natural shading. A rhizome without soaked application (control) and a rhizome with soaked by aquadestilata without PGRs (0 ppm) were used as compared items. Data was analyzed with ANOVA. Combined Analysis of Variance and t-test were performed in order to compare between 2 lots. Result showed that concentration of BAP until 150 ppm and concentration of ethephon until 800 ppm were not effective to stimulate bud induction time. Meanwhile, rhizome from 55% artificial shading had a shorter periode of dormancy than the natural shading. In the addition, plants from Pasir Sarongge rhizomes lot had more plant number, plant height, leaf number, leaf length, and leaf width than Cikabayan rhizomes lot.

Abstrak: Indonesia termasuk dalam perekonomian terbuka kecil yang tidak terlepas dari pengaruh negara lain dalam perekonomian global khususnya perekonomian negara yang besar dan kuat seperti Amerika Serikat dan Jepang, dimana kedua negara tersebut tergolong kedalam negara industri maju yang memiliki tingkat pertumbuhan ekonomi yang tinggi, perekonomian yang kuat mantap serta didukung oleh teknologi dan sumberdaya manusia yang produktif. Oleh karena itu jika terjadi gejolak dalam perekonomian negara yang besar dan kuat, negara dengan perekonomian terbuka kecil seperti Indonesia akan terpengaruh yang akan ditransmisikan kedalam perekonomian domestik baik secara langsung maupun tidak langsung.
