Cahyanto, Ferdian Dwi (2017) Sintesis Turunan Sitronelal Dari Minyak Jeruk Purut Dengan Senyawa Amina Menggunakan Ultrasonik dan Microwave serta Uji Aktivitas Antibakteri. Sarjana thesis, Universitas Brawijaya.
Abstract
Senyawa schiff base merupakan senyawa turunan sitronelal yang dapat disintesis dari reaksi kondensasi antara karbonil dengan amina primer. Dalam penelitian ini, dilakukan sintesis senyawa schiff base dari sitronelal dalam minyak jeruk purut dengan amina primer menggunakan ultrasonik dan microwave. Senyawa schiff base yang terbentuk dianalisis menggunakan spektofotometer UV-vis, FTdan IR. Senyawa schiff base yang terbentuk juga dilakukan ji aktivitas antibakteri terhadap Escherichia coli dan Staphylococcus. aureus menggunakan metode cakram. Hasil analisis menggunakan spektofotometer UV-vis didapatkan panjang gelombang maksimum pada kisaran 220-250 nm, pada analisis menggunakan FT-IR didapatkan bilangan gelombang antara 1630-1690 cm-1. Hasil uji aktivitas antibakteri menunjukkan bahwa senyawa schiff base aktif terhadap bakteri Staphylococcus. aureus tetapi tidak aktif terhadap bakteri Escherichia col
English Abstract
The schiff base compound is a derivates of citronellal compound that can be synthesized from the condensation reaction between carbonyl and the primary amine. In this study, synthesis of schiff base compounds from citronellal in kaffir lime oil with primary amine using ultrasonic and microwave. The schiff base compounds were analyzed using the UV-vis spectrophotometer, FTand IR. Schiff base compounds that also performed by antibacterial activity against Escherichia coli and Staphylococcus aureus using disc method. The result of the analysis using the UV-vis spectrophotometer was obtained by maximum wavelength in the range of 220-250 nm, in the analysis using FT-IR obtained wave number between 1630-1690 cm-1. The results of antibacterial activity test showed that the schiff base compound was active against Staphylococcus aureus but not active against Escherichia coli.
