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. Keywords: Jatropha curcas, oil, Aedes aegypti, biological larvicidal, dengue  haemorraghic fever.

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.Keywords : Kamandrah (Croton tiglium L.), biological larvacidal, Dengue Haemorraghic fever, agrobiphysicstudy.

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.

Abstract

Penelitian dilakukan di rumah kaca BalaiPenelitian Tanaman Rempah dan Obat, Bogor, dari bulan Juni sampai dengan Oktober 1989. Tujuan penelitian adalah untuk mengetahui respon setek panili terhadap pemupukan N, P, dan K. penelitian menggunakan rancangan acak kelompok dengan pola factorial, diulang tiga kali. Factor yang diuji adalah dosis pupuk N, P dan K, masing-masing 0, 1, dan 2 g/pot. Dosis pupuk dipecah dalam dua kali pemberian, yaitu pada minggu ke-3 dan minggu ke-9 setelah tanam. Hasil penelitian menunjukkan bahwa pemberian pupuk N, P, dan K secara tunggal dan interaksi antara NK, NP, dan NPK dapat meningkatkan panjang tunas. Perlakuan pemupukan yang menghasilkan panjang tunas tertinggi adalah 2 g N/pot + 2 g P2O2/pot + 1 g K2O/pot. Terhadap jumlah daun interaksi antara NK dan NP nyata pengaruhnya. Pengaruh pemupukan yang menghasilkan jumlah daun tertinggi adalah 2 g N/pot + 1 g K2O/pot.

Abstract

Effect of N, P, K fertilizer on growth and production of Cymbopogon citrates at Citayam latosal soil.A study on the Effect of N, P, K fertilizer on growth and production of Cymbopogon citrates at Citayam latosal soil. Was conducted from Juni 1992 till August 1993. The experiment was performed with a randomized block design arranged factorially. The factors tested were dosages of N (0, 0.90 and 1.8 g N per plant), P (0 and 0.46 g P2O5 per plant), and K (0 and 1.2 g K2O per plant). The result showed that N and K fertilizers significantly increased the yield. N fertilizers significantly increased the numbers of tillers, and K fertilizers significantly increased the plant height. Dosages of 1.8 g N per plant and 1.2 g K2O per plant showed the highest yield. There was no significant interaction between N, P, and K on all the parameter (number of tiller, plant height and yield).
