Retno , Dewati and Ilma, Amiriyah and Nur, Machillah (2009) PENGARUH VOLUME PELARUT, WAKTU DAN SUHU EKSTRAKSI TERHADAP PENENTUAN KADAR AZADIRACHTIN PADA BIJI MIMBA. In: Chemical Engineering Seminar Soebardjo Brotohardjono VI, 18 June 2009, Surabaya.
Organism Harassed Plants is krusial problem by this farmer. Synthetical pesticide's push its happening green revolution. Synthetical pesticide's to contain residu that dangerously divides man. Therefore begins person change over to go to nature pesticide that actually was known since forbear era. Mimba or Azadirachta Indica is a plant who can be utilized as material of nature pesticide. All a part Mimba can be utilized as material of pesticides for example leafs and its seed because contains Substance Azadirachtin. Constant variable for example, concentration etanol's 70 %, material type grades Mimba’s seed heavily 20 gram and mixing speed 350 rpm. Variable that is carried on for example, volume of solvent 100, 150, 200, 250 and 300 (ml), extraction time 1, 3, 5, 7 and 9 (hours) and on extraction temperature 30 and 50 (oC). Experimental procedure are the first insert Mimba’s seed into jugular gourd three for at extraction with volume of solvent allowable variable on 100, 150, 200, 250 and 300 (ml). Heating being started up by temperature allowable variable on 30 oC and 50 oC, mixing speed 350 rpm up to 1, 3, 5, 7 and 9 (hours). Extraction result is screened, then filtrat is analysed to know azadirachtin's and terapan's analysis. Of attempt result that does to be gotten best azadirachtin's value (% recovery) at volume 100 ml, extraction time 9 hours and on temperature 30 oC which is 61,64%. Key word : Azadirachtin, Mimba's seed, nature pesticide
