Pengaruh Pemupukan Terhadap Pertumbuhan, Produksi Dan Mutu Simplisia Purwoceng (Pimpinella Pruatjan Molkenb)

Effect of fertilizer application on production and qualityof Pimpinella pruatjan MolkenbPurwoceng (Pimpinella pruatjan Molkenb) is an Indonesianindigenous medicinal plant. Purwoceng is classified as an endangeredspecies, and its cultivation technology has not been devoleped. Theobjective of the research was to find out the effect of fertilizer applicationon the production and quality of purwoceng simplisia. The research wasconducted in Sikunang, Dieng, Wonosobo, Central Java from 2004 until2005. The treatments of fertilizer application on 2.4 m 2 were (1) control(without fertilizer); (2) 9.6 kg dung manure (dm); (3) 96 g urea + 48 gSP36 + 72 g KCl; (4) 9.6 kg pk + 96 g urea + 48 g SP36 + 72 g KCl; (5)9.6 kg pk + 96 g urea + 48 g SP36; (6) 96 kg pk + 9.6 g urea + 72 g KCl;(7) 9.6 kg pk + 48 g SP36 + 72 g KCl. The experiment was designed inrandomized block designed with four replications. The result of theresearch showed that the treatments of 9.6 kg dm + 96 g urea + 48 g SP36+ 72 g KCl/2.4 m 2 and 96 g urea + 48 g SP36 + 72 g KCl/2.4 m 2 increasedthe simplisia production and quality compared with control. The simplisiaproduction increased up to 40% and the stigma sterol content in the rootsincreased up to 11 – 14 times. The content of sitosterol in the plants withfertilizer application was 6.7 – 17.11 ppm but in the plants withoutfertilizer application was zero. The content of bergapten in shoot part ofplant with fertilizer application was 4.92 – 5.56 ppm, but in the shoot partwithout fertilizer application was zeros. The production and quality ofsimplisia with the fertilizer application of 96 g urea + 48 g SP36 + 72 gKCl/2.4 m 2 were not significantly different from those with fertilizerapplication of 9.6 kg pk + 96 g urea + 48 g SP36 + 72 gKCl/2.4 m 2 . Ithappened probably because the organic soil content was high, so that theapplication of 40 ton/ha of dung manure did not give any effect.Furthermore, to increase the optimum production of purwoceng simplisia(6.98 kwt/ha) with high quality it needs 283 mg N, 55 mg P dan 356 mgK/plant or 23.50 kg N, 6.30 kg P, and 38.90 K/ha

Pola Pertumbuhan Dan Serapan Hara N, P, K Tanaman Bangle (Zingiber Purpureum Roxb.)

Growth pattern and nutrient uptake of N, P and K onpurple ginger (Zingiber purpureum Roxb)One of the problems in cultivation of purple ginger (Zingiberpurpureum Roxb) is limited cultivation technology. Therefore, the study on its growth pattern and nutrient uptake of N, P, and K is very importantto support its cultivation technology. The objective of the research was tofind out data of growth pattern, growth rate, nutrient uptake, and simplisiaquality. Field trial was conducted in farmers land in Bogor from May 2001to March 2002. The soil is latosol and the altitude is 250 m asl. Plot sizewas 6 x 1,5m, and plant spacing was 50 x 40 cm. Observation on thegrowth pattern and nutrient uptake were carried out at different ages of : 2,3, 4, 5, 6, 7, 8, 9, and 10 months after planting. Six samples were taken atevery growth stage of the plant. The results showed that the growth rateand the nutrient uptake of N, P, and K linearly increased, in line with theincrease of plant ages. Yield of essential oil at 10 MAP was 12.10 ml/plant. The amount of dry weight accumulation was 701.0 g/plant, to produce417.97 g simplisia/plant needed nutrient uptake of N, P and K, respectivelywas 8.48, 1.72 and 4.02 g/plant

PENGGALIAN IPTEK ETNOMEDISIN DI GUNUNG GEDE PANGRANGO

Hutan tropika Indonesia kaya keane-karagaman species tumbuhan, sedikitnya ter-dapat 40.000 jenis termasuk yang berkhasiat obat. Disamping itu, keberadaan 370 suku asli dengan keanekaragaman adat dan budayanya, turut memberikan keuntungan sendiri bagi kha-sanah etnomedisin dan budaya bangsa. Proses pewarisan IPTEK etnomedisin umumnya dila-kukan secara oral. Kondisi yang demikian akan mendorong terjadinya erosi IPTEK tersebut, disamping karena masuknya budaya modern. Oleh karena itu perlu dilakukan penggalian dan pengembangan IPTEK etnomedisin. Kegiatan pengkajian ini telah dilaksanakan di kawasan Taman Nasional gunung Gede Pangrango pada bulan Januari sampai dengan Desember 2001. Survey dilakukan di 6 lokasi (gunung Gede Pangrango), mencakup 2 kabupaten (Sukabumi dan Cianjur). Penentuan lokasi dilakukan se-cara sengaja, dengan memperhitungkan kemu-dahan untuk mencapai lokasi. Narasumber yang diwawancarai juga ditetapkan secara se-ngaja. Hasil penelitian menunjukkan bahwa pemanfaatan etnomedisin di kawasan gunung Gede Pangrango, terbatas pada dukun beranak. Kawasan gunung Gede Pang-rango, telah diin-ventarisasi sebanyak 23 jenis penyakit dengan 72 resep yang menggunakan 80 jenis tumbuhan obat. Hasil analisis mutu beberapa jenis sim-plisia dari lokasi survey memenuhi standar mutu yang ditetapkan MMI (Materia Medika Indonesia), sehingga memiliki prospek untuk produksi bahan baku industri obat tradisional, kosmetika dan lainnya.
