"Makalah ini membahas pengembangan Sistem Penciuman Elektronik menggunakan 16 buah sensor kuarsa terlapis membran sensitif. Penulis telah mengembangkan Sistem Penciuman Elektronik dengan jumlah sensor sebanyak 4 buah, akan tetapi sistem ini hanya mampu membuat klasifikasi aroma campuran dengan tingkat pengenalan dibawah 40%. Pengembangan sistem dilakukan dengan meningkatkan jumlah sensor untuk memperbesar dimensi ruang pengamatan dan peningkatan frekuensi dasar sensor untuk mendapatkan akurasi yang lebih tinggi.
Hasil penelitian menunjukkan bahwa sistem 16 sensor mempunyai kapabilitas yang tinggi untuk klasifikasi aroma campuran. Tingkat pengenalan sistem dengan 16 sensor untuk aroma campuran dengan 6 tingkat konsentrasi alkohol berkisar 89.9%, bila diproses secara terpisah, sedangkan apabila dilaksanakan secara ?batch? akan menghasilkan tingkat pengenalan sekitar 82.4%.

An artificial odor recognition system is developed for discriminating odors. This artificial system consisted of 16 quartz resonator crystals as the sensor array, a frequency modulator and a frequency counter for each sensor that are connected directly to a microcomputer. We have already shown that the artificial odor recognition system with 4 sensors is high enough to discriminate simple odor correctly, however, when it was used to discriminate compound odors, the recognition capability of this system is dropped significantly to be about 40%.
Results of experiments show that the developed artificial system with 16 sensors could discriminate compound aroma based on 6 gradient of alcohol concentrations with high recognition rate of 89.9% for non batch processing system, and 82.4% for batch processing of the classes of odors."

"To improve the recognition accuracy of a developed artificial odor discrimination system for three mixture fragrance recognition, Fuzzy similarity based Self-Organized Network inspired by Immune Algorithm (F-SONIA) is proposed.Minimum, average, and maximum values of fragrance data acquisition are used to form triangular fuzzy numbers. THen, the fuzzy similarity measure is used to define the relationship between fragrance inputs and connection strengths of hidden units. The fuzzy similarity is defined as the maximum value of the intersection region between triangular fuzzy set of hidden units. In experiments, performances of the proposed method is compared with the conventional self-organized Network inspired by Immune Algorithm (SONIA) and the Fuzzy Learning Vector Quantization (FLVQ). Experiments show that F-SONIA improves recognition accuracy of SONIA by 3-9%. Comparing to the previously developed artificial odor discrimination system that used FLVQ as pattern classifier, the recognition accuracy is increased by 14-15%."
