چکیده
Aroma teh merupakan sesuatu yang sulit diukur karena membutuhkan kejelian dalam indra penciuman sehingga untuk mengukur aroma rangka mempertahankan kualitas yaitu menggunakan alat Hidung elektronik/enose terdiri dari sensor-sensor digunakan mendeteksi atau bau. elektronik/Enose terbuat beberapa larik sensor gas dan memiliki sistem kerja seperti manusia. Melalui e-nose hijau dapat diidentifikasi diklasifikasi metode LDA (linear discriminant analysis). Tujuan penelitian ini mengetahui klasifikasi merek hidung elektronik analisis hasil data keluaran linear diskriminan (LDA) berdasarkan aromanya. Hasil pengukuran (e-nose) berupa kurva sensing flessing, dicari luasannya dengan integral trapesium. Data luasan diolah LDA. Dilakukan pengujian tingkat akurasi presisi uji validitas reabilitas pengukuran. berbasis elektronik, menghasilkan empat cluster besar pengolahan kelompok TT TJ, TCB, TKD TM. Dari didapatkan Fungsi pertama (FD1) kedua (FD2) mempunyai nilai 48,8% 37,6% total varians. Nilai dua fungsi sebesar 86,4 % sudah mampu mengklasifikasikan secara baik grafik score plot.

An electronic nose based on coupling of headspace (HS) with a mass spectrometer (MS) has been used in this study to classify and characterize a series of beers according to their production site and chemical composition. With this objective, we analyzed 67 beers of the same brand and preparation process but produced in different factories. The samples were also subjected to sensory evaluation b...
متن کاملThymineless death in polA+ and polA- strains of Escherichia coli.
The extreme sensitivity of polA(-) cells to thymineless death is due, primarily, to the absence of an extended lag prior to the commencement of death. Once thymineless death has commenced, the rate in polA(-) cells is only slightly faster than in polA(+) cells.
