Turnitin_MICRO CLIMATE ASSESSMENT OF MEDICINAL PLANT HABITAT FOR THE FIRST STEP OF DOMESTICATION

Abstract

Indonesia is known as a storehouse of medicinal plants (herbal) called live laboratory, but unfortunately 78% of medicinal plants were taken directly from the forest. The cultivation of medicinal plants until present day is only 20%. In order to prevent the extinction and commercialization of medicinal plants it is essential to develop the cultivation of medicinal plants either exstitu The process of domestication of wild plants into crops by planting in the new habitat. The preparation of planting of medicinal plants need to attent the technical aspects, especially the abiotic environment such as; temperature, humidity, and light intensity. Based on that, as an the first initial step in order domestication of some medicinal plants of Malinau and Harakit in South Kalimantan, it is necessary to do a study on the microclimate them, so that later can be developed elsewhere, with the micro-climatic conditions can be created like in their natural habitat. the results showed herbs grown at an altitude of 132-223 m above sea level, has a micro climate is very variable, temperature of 28-41°C, humidity 53-89%, and light intensity 1-100%. Manggarsih (Parameria laevigata (Juss.) Moldenke) is located on the highest point (oil palm plantations), with high temperatures, low humidity and high light intensity, while kayu sisil (Litsea sp) and bayuan (Coptosapelta tomentosa Korth.) near the riverbank, with altitude low temperature and low light intensity and high humidity. Meanwhile pikajar (Schizaea digitata (L) Sw.) and pasak bumi (Eurycoma longifolia) with a wider spread of habitat, with an interval of temperature, humidity and light intensity were great. Tambar bisa (Clausena excavata Burm.f.) can be found at the site of lowest to highest, but humidity should be high and low light intensity. Akar waring (Coptosapelta tomentosa Valeton ex K.Heyne) was found in oil palm plantations, rubber plantations until secondary forests.
