Pests of Patchouli Plant and Their Damage

Generally, patchouli is still cultivated traditionally in Indonesia. Improved technology such as pest and disease control methods, is needed. Observation of pests on patchuoli was carried out at Sukamulya experimental garden from Agustus 2004 to January 2005. Further research was carried out at the laboratory and greenhouse of the Indonesian Spice and Medicinal Crops Research Institute to examine the damage of the patchouli plant due to the main insect attack. The experiment was arranged in a randomized block design, with 6 treatments and 4 replications. The experiment used one month-old patchouly seedlings of Sidikalang variety and the main insect (third instar grub) The white grub was invested on pathouli seedling. Each plant was invested with 0, 1, 2, 3, 4, 5, grubs as treatments. The results showed that grasshopper (Valanga sp), aphids (Myzus persicae), termite (Coptotermes sp), snail (Achatina sp) and white grub (Exopholis hypoleuca) attack the patchouly plant with low up to high damages. It was observed that the grub is a dominant pest which attacked 1.800 out of 15.000 patchouli plants at Sukamulya experimental garden. Treatments grubs on patchouli seedlings at one, two, three, four and five grubs/polybag caused death on the seedlings at 14, 13, 10, 7 and 7 days after investation, repectively.

Formulation of Granule Effervescent from Ginger Extract

Ginger (Zingiber officinale Roxb., Zingiberaceae) has been widely used in pharmaceutical, cosmetic and food industries. However, ginger product as beverages in the form of effervescent granule has not been known yet. Far that reason an experiment was conducted to find the formula for ginger effervescent granule. In this experiment, 12 formulas had been tried using treatments as follow : (a) Type of extract (water extract 4% and 6% and alcohol extract 0.4% and 0.6%), (b) Addition of citric acid (2%, 3% and 4%). The observations was conducted on : (1) Physical propertis of granule (moisture content, and dissolution rate), (2) Organoleptic test which include of preference to the colour, taste and aroma. The physical propertis analysis showed that granule made from alcohol extract met the quality requirement while the granule made from water extract did not meet the requirement, due to its moisture content i.e 0.63-0.74% which was higher than requirement (0.1-0.5%).The organoleptic test to 20 panelists showed that the accepted formula was formula number 10 which had colour, aroma and taste score of 3.35, 3.50 and 3.05 respectively, This formula made from 0.6% alcohol extract and 2% citric acid. Key words : Formulation, granule, effervescent, extract and ginger. Sri Yuliani, Nunik Purwanti dan Teti Indrawati; Balai Penelitian Tanaman Rempah dan Obat

Effect of Benzyl Adenin (BA) and NAA As Growth Regulatur On The Growth Of Temoe Lawak (Curcuma xanthorriza Roxb.) Through In Vitro

Micropropagation of temoe lawak in vitro has been conducted in Tissue Culture Laboratory Germplasm and Breeding Division at Research Institute for Spice and Medicinal Crops,Bogor from October 1999 to July 2000. Shoots of temoe lawak from Sukamulya Research Instalation were used as explants. Shoots were sterilized with sterilant such as 70 % alcohol , 0.2 % mercuri clorite , 20 % Clorox and then cleaned with aqudes before they are cultured. Murashige and Skoog (MS) which was added with vitamine from B group were used as basic medium. Several concentration of benzyl adenin i.e : 0; 0.5; 1.0; 1.5 and 2.0 mg/l singly and combination with NAA 0.5 mg/l were used as treatments. The treatment were arranged in Randomized Completely Design with three replications. Each replication consited of five bottles. The parameters observed were average the number and lengths of shoot , number of leaves and roots and the culture performance visually. The result showed that the greatest number of shoot and leaves were found by using 1.5 mg/ l BA during 8 weeks. The greatest roots were found on 1.0 mg/l BA + 0.5 mg/l NAA . BA used singly or combined with NAA could be used on micropropagation of temoe lawak in vitro. Key words : Curcuma xanthorhiza, BA, NAA, in vitro.
