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.

Judul: Inisiasi Rimpang Mikro Kaempferia parviflora Secara In Vitro dengan Penambahan BAP dan Sukrosa
Abstrak: Kaempferia parviflora is a medicinal plant that contains secondary metabolites and efficacious for treating various diseases. Rapid multiplication of K. parviflora through its rhizome is hamprered by the long period needed to produce the rhizome. The objectives of this research were to obtain the best sucrose concentration and to determine the best BAP concentration in the in vitro micro rhizome initiation of K. parviflora. The experiment was arranged in a randomized complete block design with two factors and three replications. The first factor was BAP concentration, consisted of three levels i.e. 0, 2, and 4 mg L¯1. The second factor was sucrose concentration, consisted of four levels i.e. 0, 30, 60, and 90 g L¯1. Data obtained were analyzed by F-test, followed by DMRT (Duncan Multiple Range Test) at 5 % significant level. Sucrose concentration significantly affected the number of shoots and plantlets fresh weight. The results showed that K. parviflora could form micro rhizome in vitro, as indicated by the similar anatomical structure compared to the rhizome produced in vivo. K. parviflora cultured in MS medium cointaining 90 g L¯1 sucrose without BAP had the highest number of micro rhizome at 8 WAC.

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.
