Abstract


Telah dilakukan penelitian tentang pemisahan dan karakterisasi etanol dari nira aren (Arenga pinnata). Pemisahan dan analisis dilakukan dengan teknik distilasi secara bertahap, dilanjutkan dengan penentuan sifat-sifat fisik; sedangkan identifikasi struktur dilakukan secara spektrofotometer inframerah, kromatografi gas-spektrometer massa, spektrometer RMI1H. Hasil identifikasi struktur dengan spektrofotometer inframerah menunjukkan adanya gugus fungsi hidroksil (-OH) dan alkil (-C2H5), sedangkan hasil identifikasi dengan spectrometer RMI1H menunjukkan 3 karakteristik puncak hydrogen yakni H pada gugus hidroksil (–OH), metilen (-CH2-) dan metil (-CH3). Selanjutnya, hasil uji kromatografi gas-spektrometer massa menunjukkan 1 puncak dengan kadar etanol nira aren mencapai 100% serta fragmentasinya mengikuti pola struktur etanol (C2H5OH).
