Abstract

High life demands nowadays make the individual emotional state change easily. Music is one of many media that is used to stabilize a person’s emotional condition. However, wrong use of music can worsen a person’s emotional condition, as in the case of today’s society.To prevent that, an application that can detect the user’s facial expression to stabilize the user’s emotional state through music is developed. The expression on the face is determined by the position of eyebrows, eyes, mouth, and wrinkles features. The positions of detected features are compared with those in a neutral face that has been previously calibrated. The difference of features’ positions will be used as input of the trained neural network to determine the expression on the detected face.Through some experiments, the accuracy of detection of facial features and facial expressions are known. The detected expression will trigger the playback of music to stabilize the user’s emotional condition. The weakness of this application is that the music library must be set manually by the user.

Abstract

Voting atau pemungutan suara telah menjadi salah satu metode yang digunakan manusia untuk menentukan keputusan dalam sebuah hal. Voting juga sering digunakan dalam menentukan hal-hal yang sangat penting, seperti menentukan wakil-wakil rakyat, atau menentukan pemimpin baru. Di samping itu, saat ini pemungutan suara masih dilakukan dengan cara konvensional, yaitu menggunakan kertas dalam melakukan pembuatan ballot, pencoblosan, dan perhitungan suara. Hal ini dapat mengakibatkan terjadinya human error yang mempengaruhi hasil pemungutan suara dan dapat merugikan pihak tertentu. Selain itu, pemungutan suara yang dilakukan dengan teknologi komputer juga mempunyai masalah tertentu. Banyak pihak yang meragukan keamanan dari vote yang mereka lakukan, apakah benar masuk dan terhitung di akhir pemungutan suara, atau tidak.Untuk menjawab persoalan tersebut, dirancang suatu sistem pemungutan suara elektronik dengan memanfaatkan teknologi Blockchain dalam aplikasi berbasis website. Dengan memanfaatkan teknologi ini, data pemungutan suara yang telah dilakukan tidak dapat diubah, digandakan ataupun dihapus. Sehingga dapat meningkatkan keamanan dari pemungutan suara. Selain itu, teknologi ini juga dapat menjaga kerahasiaan dari pihak yang melakukan pemungutan suara. Aplikasi ini juga membantu proses pemungutan suara agar lebih mudah dalam hal pengelolaan pihak terkait, pemungutan suara, hingga perhitungan suara.Dari penelitian dan pengujian sistem yang telah dibuat, aplikasi dapat membantu memudahkan penyelenggaraan pemungutan suara. Teknologi blockchain yang digunakan mampu membantu menyimpan data hasil pemungutan suara yang transparan dan dapat diakses oleh publik. Teknologi ini juga membantu menjaga kerahasiaan dari voter. Data pemungutan suara juga tidak dapat diubah, digandakan atau dihapus. Selain itu, teknologi blockchain juga membantu melakukan verifikasi dan memilah data vote yang valid.

Abstract

According to Cisco report in 2015, Internet usage has increased more than five times in the last 5 years, and it was projected to increase three times over the next 5 years. Increasing use of the internet is mostly caused by certain internet applications such as Flash, MPEG, video streaming, and P2P file sharing. Therefore, bandwidth configuration with traffic shaping method in Linux is needed in order to provide the needs of the Internet in accordance with user class. nDPI is used for classifying the data traffic in the Internet network.Work on the thesis focuses on the evaluation of the use of nDPI on bittorrent P2P applications. The evaluation was done using iptables to perform the data traffic marking and traffic control (tc) to do the bandwidth shaping. Bandwidth monitoring used iptraf applications on Linux and Networx application on the client.Based on testing performed, traffic shaping with nDPI coupled with cache successfully limited the bandwidth usage of  bittorrent P2P applications. The nDPI with cache was evaluated in different cache sizes and bandwidth limits. nDPI with size cache of 1024 entries is recommended. nDPI can not fully classifying bittorrent traffic correctly.
