Abstract

The aim of the research is to obtain the ecological condition and propagation of kamandrah (Croton tiglium L.) and determination of its potency as biological larvacidal for preventing dengue haemorraghic fever. Agrobiophysic study indicated that Croton tiglium L. plant need full sunlight(> 70 %). low intensity of sunlight could decrease the ability of plant to produce seed. The plant could grow well on podzolic land (30-50 m upon sea surface). Seed of kamandrah from Ampah has growth percentage of 43.8 °/o, height of 27.5 em, stem diameter of 5 em, total leaves of 10, and total primary branches of 2. Phytochemical assay resulted that among other part of Kamandrah, Kamandrah seed has highest alkaloid content. Because alkaloid compound has high larvicidal activity, kamandrah seed has high potency as larvicide. Among all of extracts of part of plant, oil of Croton tiglium L. has the highest potency as biological larvacidal with 863.67 ppm of LC50 for 24 hours of treatment.

Abstract

Recently, Indonesia has big problem caused by dengue haemorraghic fever with A. aegypti as vector. Potential medicine and vaccine for curing this disease have not been found. The effective method to prevent this disease is the use of A. aegypti larvicidal. The chemical larvicidal has disadvantage for evironmental aspect. To solve this problem, the biological larvicidal has a good chance to develop. Indonesia has megadiversity which can be developed as biological larvicidal. Crude aqueous extracts and ethanol extracts of Jatropha curcas (Jarak pagar) seed and oil of Jatropha curcas were evaluated for larvicidal potential against the Aedes aegypti mosquito. Among all extracts, Jatropha curcas oil possessed a highest activity against the 3th instar larvae of Aedes. LC50 values of Jatropha curcas oil was 1507 ppm for 24 h and 866 ppm for 48 h. It was suggested that the Croton tiglium oil and Jatropha curcas oil possess larvicidal properties that could be developed and used as biological larvicidal.

Abstract

Untuk mengetahui pengaruh keke-ringan pada tanah bergaram NaCl terhadap pertumbuhan tanaman nilam (Pogostemon cablin Benth.) telah dila-kukan penelitian di rumah kaca Balai Pene-litian Tanaman Obat dan Aromatik (Balittro) Bogor pada Juni sampai November 2007. Faktor yang diuji adalah : 1) keadaan tanah, terdiri atas 2 taraf (keadaan lembap dan kering); dan 2) kadar garam NaCl tanah terdiri atas 3 taraf (0, 1.000, dan 2.000 ppm). Faktor-faktor yang diuji tersebut disusun dalam ran-cangan acak lengkap dengan 10 ulangan. Sedangkan parameter yang diamati meli-puti komponen tinggi tanaman, jumlah daun, jumlah buku, jumlah cabang, dia-meter batang, serta bobot basah dan kering biomas. Hasil penelitian menun-jukkan bahwa faktor keadaan dan kadar garam NaCl tanah mempengaruhi pertum-buhan tanaman nilam. Pengaruh interaksi antara kedua faktor tersebut hanya dijum-pai pada komponen diameter batang. Pada kondisi tanah kering, kadar garam NaCl 1.000 ppm atau lebih sangat nyata meng-hambat pertumbuhan diameter batang, tetapi tidak berpengaruh ketika tanah cukup lembap (basah). Kedua faktor secara individu berpengaruh nyata ter-hadap komponen pertumbuhan lainnya pada tanaman nilam. Keadaan tanah basah nyata lebih baik pengaruhnya ter-hadap perkembangan tanaman dibanding tanah  dengan  keadaan  kering.  Demikian   pula kadar garam NaCl tanah yang semakin meningkat ternyata semakin memperburuk pertumbuhan dan perkembangan tanaman nilam.

Abstract

Research on the effect of concentration and frequency of foliar fertilizer application on growth of vanilla (Vanilla planifolia Andrews) was carried out at the experimental garden of The Indonesian spice and medicinal crops Research Institute, West Java, from May until October, 1996. The experiment was conducted with a randomized block design, with 3 replicates and 10 treatments. The treatments were control, 1,5 g foliar fertilizer/4 liter/twice a week, 1,5 g foliar fertilizer/4 liter/once a week, 1,5 g foliar fertilizer/4 liter/once in two weeks, 3 g foliar fertilizer/4 liter/twice a week 3 g foliar fertilizer/4 liter/once a week, 3 g foliar fertilizer/4 liter/ once in two weeks 4,5 g foliar fertilizer/4 liter/twice a week 4,5 g foliar fertilizer/4 liter/once a week, and 4,5 g foliar fertilizer/4 liter/once in two weeks. The foliar fertilizer used was NPK (30-10-10) plus trace elements, such as Fe, Co, B, Mo, Mg and vitamine B1. The result showed that application of 1,5 g foliar fertilizer/4 liter/twice a week and 4,5 g foliar fertilizer/4 liter/once in two weeks were the best for the growth of vanilla at nursery. However, application of 4,5 g foliar fertilizer/4 liter/once in two weeks is efisien.

Abstract

ABSTRAKTanaman   akarwangi (Vetiveria   zizanioides   Stapf.) memerlukan kalium (K) dalam jumlah yang memadai. Pemberian K ke tanah dalam jumlah banyak akan tidak efektif. Oleh karena itu, ketersediaan hara K baik di tanah maupun sumber lainnya harus di kelola secara baik. Selain K, tanaman akarwangi juga memerlukan ketepatan umur panen. Umur panen yang tidak tepat akan  mempengaruhi  produksi  dan  mutu  minyak. Waktu  panen  yang  tepat  memenuhi  produksi  dan mutu   vetiverol   yang   tinggi.   Pada   tanah   yang mengandung   K   sedang (>0,35   me/100   g   tanah), penambahan   pupuk   K   ke   tanah   tidak   mampu meningkatkan   kandungan   senyawa   alkohol   pada akarwangi. Panen produksi akar dan minyak terbaik adalah umur 14 bulan setelah tanam (BST) dengan kandungan   vetiverol     >50%.   Perbedaan   senyawa alkohol yang terbentuk terjadi pada umur 12 BST dan 14  BST.  Adapun  senyawa  alkohol  yang  terbentuk adalah    Cis-.alpha.-copaene-8-ol,    valerenol,    beta-eudesmol, globulol, (+) -gamma-castol, zizanol, dan 1-cloro-2,4-dimethroxy-3-methylphenol.  Pada  umur 12 BST, senyawa yang mengandung alkohol yaitu cis-.alpha.-copaene-8-ol,                             (+)   -gamma-castol,    beta-eudesmol,  globulol  dan  valerenol  sedangkan  pada umur 14 BST yaitu beta.-Eudesmol, (+) -gamma-castol, zizanol,   dan 1-cloro-2,4-dimethroxy-3-methylphenol. Perbedaan ini perlu diteliti lebih lanjut.Kata kunci : Minyak akarwangi, Kalium, umur panen The Role And Management of Potassium in Cultivation of Vetiver CropsABSTRACTVetiver crop need potassium (K) nutrient. Using of K on vetiver over dosage, so inefficient. Besides that, the vetiver crops need time of harvest. Time of harvest can be affecting to product and quality of oil. Therefore, K nutrient in soil, from fertilizer or the other source must be managed with good and harvest time also. The medium  K  (>0,35  me/100 g  soil)  of  soil  could  not increase of the alcohol compound. Time of harvest (14 month after planting (MAP)) was high production (dry weight of root and oil) and vetiverol (>50%). The result of research showed that component of alcohol oil was different between harvesting at 12 (MAP) and 14 MAP. The component of alcohol were cis-alpha-copaene-8-ol, beta-eudesmol, valerenol, globulol, (+)-gamma-castol, zizanol,   dan 1-cloro-2,4-dimethroxy-3-methylphenol There were four essential components of oil (alcohol groups ) at 12 MAP were cis-alpha-copaene-8-ol, beta-eudesmol, (+)-gamma-castol, valerenol and globulol. At  14  MAP  were  beta-eudesmol,  (+)-gamma-castol, zizanol,   dan 1-cloro-2,4-dimethroxy-3-methylphenol. Different of this component must be research on the future.Key words : Vetiver oil, potassium, time of harvest.
