ANALISIS KOMPONEN KIMIA MINYAK ATSIRI DARI RIMPANG KUNYIT (Curcuma longa. L) DAN UJI PESTISIDA NABATI
TERHADAP LALAT BUAH (Bactrocera sp.)
ABSTRAK
Minyak atsiri rimpang kunyit (Curcuma longa. L) telah diisolasi dengan metode hidrodestilasi menggunakan alat Stahl selama ±4-5 jam menghasilkan minyak atsiri 0,30% (b/b). Komponen kimia minyak atsiri rimpang kunyit dianalisis menggunakan GC-MS menunjukkan ada 7 senyawa, yaitu alfa-felandren, para-cimen, 1,8 cineol, benzen metil, benzen,1,3,5-trimetil-, beta-tumeron, dan, alfa-tumeron. Dimana komponen utamanya adalah beta-turmeron 66,18%, alpha-turmeron 17,06%, 1,8-sineol 8,57%, alpha- fellandren 6,49%. Uji pestisida nabati dilakukan dengan metode perbandingan konsentrasi. Uji pestisida nabati minyak atsiri rimpang kunyit (Curcuma longa. L) menunjukakan mortalitas lalat buah (Bactrocera sp.) tertinggi sebesar 100% pada konsentrasi 3% (v/v) dan 2% (v/v).

ANALYSIS OF CHEMICAL COMPONENTS OF ESSENTIAL OILS FROM TURMERIC RHIZOME (Curcuma longa. L) AND PESTICIDES
VEGETABLE TESTS ON FLIES OF FRUIT (Bactrocera sp.)
ABSTRACT
The essential oil of turmeric rhizome (Curcuma longa. L) has been isolated by hydrodestilation method using Stahl tool for ± 4-5 hours yields 0.30% (b / b) essential oil. The chemical components of essential oil of turmeric rhizomes analyzed using GC-MS indicate that there are 7 compounds, namely alpha-felandren, para-cimen, 1,8 cineol, benzen methyl, benzen, 1,3,5-trimethyl-, beta-tumeron, and, Alpha-tumeron. The main components are beta-turmeron 66,18%, alpha-turmeron 17,06%, 1,8-sineol 8,57%, alpha- fellandren 6,49%. Vegetable pesticide test done by comparison method of concentration. Vegetable pesticide test of essential oil of turmeric rhizome (Curcuma longa. L) indicates mortality of flies of fruit (Bactrocera sp.) Highest at 100% at concentrations of 3% (v / v) and 2% (v / v).
