Untuk menunjang pemantauan konsentrasi manusia, perlu adanya pemahaman mengenai respon sinyal dari EEG terhadap dua kondisi manusia ya itu saat sedang konsentrasi penuh dan konsentrasi tidak penuh (adanya distraksi). Dalam mengolah data sinyal EEG tersebut, dibutuhkan metode algoritma dan klasifikasi sinyal untuk mendapatkan hasil data sinyal dari dua kondisi tersebut. Pada penelitian ini akan dijelaskan tentang sistem perancangan pendeteksian konsentrasi manusia berdasarkan sinyal EEG. Metode yang digunakan adalah Fast Fourier Transform (FFT) dan Discrete Wavelet Transform (DWT) sedangkan dalam algoritma klasifikasinya menggunakan Support Vector Machine (SVM). Hasil yang telah didapatkan dalam pengujian ini adalah SVM lebih mampu untuk mengklasifikasikan sistem dengan kernel RBF menggunakan 30% holdout validation. Keakurasian dari sistem ini adalah 91% pada metode DWT dan 72% pada metode FFT. Sehingga, dari kedua ekstraksi metode FFT dan DWT, yang memiliki nilai ekstraksi terbaik adalah DWT.

ABSTRACTTo support the monitoring focused human concentration, there is a need to understand the response of signals from EEG in two conditions which are when human is in full concentration and less concentration (presence of distraction).  To process those EEG signal data, an algorithm method and classification is needed to get the results of signal data from these two conditions In this research, the system of detecting design of human concentration levels based on EEG signals will be explained. The used methods are Fast Fourier Transform (FFT) and Discrete Wavelet Transform (DWT) while the classification algorithm uses Support Vector Machine (SVM).  The result of this research shows that by using SVM, a much more reliable result is achieved when a kernel RBF is used with 30% holdout validation. The result of the aforementioned method yields a 91% accuracy with DWT method and a 72% accuracy with FFT.

"Systems Engineering Principles and Practice is a national standard textbook for the study of traditional systems engineering for advanced undergraduate and graduate students. It addresses the need for an introductory overview, first-text for the development and acquisition of complex technical systems. The material is well organized, readable and fundamental to learning how to think like a systems engineer and carry out best practices in the field. Since systems engineering is still developing as a discipline, there have been new concepts and practices that have entered the field since the text was published in 2003. As an increasing number of students have used the text, topics have been discovered that would benefit from expansion, integration and clarification. The proposed second edition will be developed by colleagues of the original authors to upgrade this unique interdisciplinary guide to systems engineering to maintain relevance and currency in this rapidly changing and demanding field"--"

"The book discusses delay-time modelling for multi-unit technical systems in various reliability structures, examining the optimum maintenance policies both analytically and practically, focusing on a delay-time modelling technique that has been employed by researchers in the field of maintenance engineering to model inspection intervals. It organizes the existing work into several fields, based mainly on the classification of single- and multi-unit models and assesses the applicability of the reviewed works and maintenance models. Lastly, it identifies potential future research directions and suggests research agendas."

"Telah dibuat suatu rancang bangun sistem mekanik alat pembuat jalur sobekan kertas dan cacahnya. Sistem ini dirancang dengan tujuan untuk mempermudah dalam pengerjaan finishing percetakan, apalagi untuk perusahaan percetakan kecil dan menengah, karena tidak perlu memerlukan biaya lebih besar untuk membeli alat yang besarnya. Dengan adanya sistem mekanik ini dapat mempermudah dan mendukung dalam sistem kontrol untuk otomatisasinya, karena dalam sistem mekanik tersebut terdapat peletakan sensor sensor yang biasa digunakan sebagai logika untuk sistem kontrolnya. Sistem mekanik ini terdiri dari plat besi, as, motor dc, motor ac dua arah, solenoid, roda karet, belt konveyor, pisau potong yang bermata khusus, dudukan sensor dll. Dengan demikian sistem mekanik ini tidak merupakan untuk simulasi lagi melainkan alat yang memang sudah dapat diterapkan dalam keadaan realnya, hal ini dikarenakan ukuran alat ini disesuaikan dengan area kertas yang biasa digunakan dalam percetakan, dengan batasan sampai ukuran kertas folio. Pada sistem ini digunakan mekanik untuk pergerakan dudukan sensor letak jalur sobekannya, sehingga dengan demikian letak jalur sobekannya tidak pada satu tempat saja melainkan dapat diatur sesuai yang diinginkan.

Was made by an designing to develop its count and paper rip band maker appliance mechanic system. This system is designed as a mean to water down in workmanship finishing printing office, and surely for the middle and small printing office company, because needn't cost money bigger to buy appliance which is the level of. With this mechanic system existence can water down and support in control systems for otomatisasinya, because in the mechanic system there are censor censor situating which commonly use as logic for its control systems. this Mechanic system is consisted of by the iron plate, ace, motor dc, motor ac two direction, solenoid, rubber wheel, belt conveyor, crosscut knife is which have the special eye, sensor placement etc. Thereby this mechanic system do not represent for the simulation again but the appliance which it is true have applicable in a state of the real, this matter because of size measure this appliance is adapted for by a paper area which commonly use in printing office, with definition until size measure of folio paper. At this system is used by a mechanic for movement sensor placement of rip band situation, so that thereby its rip band situation do not at one organizable just place but as wanted."
