Abstract

Penggunaan smartphone dari tahun ke tahun mengalami peningkatan yang sangat pesat. Smartphone dengan system operasi Android, Blackberry, Windows Phone, IOS, dan beberapa system operasi lainya berkembang dengan pesat dan banyak orang yang sudah dapat menggunakan smartphone tersebut. Perkembangan ini dapat dimanfaatkan juga dalam dunia kerja seperti untuk pekerjaan memasarkan barang. Dengan membuat aplikasi pada smartphone maka pekerjaan yang biasanya membutuhkan catatan-catatan dapat dimasukan ke dalam smartphone sehingga menjadi lebih praktis. Seperti daftar barang, nota pemesanan, dan data customer dapat dimasukan ke dalam smartphone dan dapat diakses oleh sales yang membawa smartphone.Aplikasi yang dikembangkan menggunakan PhoneGap yang dibuat dengan bahasa pemrograman HTML 5, Javascript, dan CSS. Untuk komunikasi data antara device dengan data pusat perusahaan menggunakan JSON. Untuk bagian server tidak memiliki tampilan sama sekali karena hanya berfungsi untuk menghubungkan device dengan data perusahaan.Aplikasi ini dapat memberi kemudahan kepada sales untuk dapat melakukan penjualan pada customer. Sales dapat dengan mudah mendapatkan data barang yang akan dijual, sales juga dapat mengenal customer dengan lebih baik, dan juga sales juga akan lebih terbantu dengan adanya fitur upload data transaksi yang dapat memudahkan sales untuk dapat mengumpulkan data pemesanan yang telah dibuat sebelumnya tanpa antri pada kantor perusahaan.

Abstract

Transcription of music is an active research problem in computer science and has many applications in digital music. The use of time-domain filter to improve sound quality and adding sound effects is commonplace, but the use of filter for pitch detection is rarely explored. This work thesis aims to create a pitch detection system based on digital filter and test it’s performance in guitar and piano signals. IIR Comb Filter and Peak2 onset detection is chosen as the main algorithm for this application. IIR Comb Filter have notches, zero values corresponding to a certain frequency and all it’s harmonic frequencies. If make IIR Comb Filter correspond to a pitch frequency, all its harmonic frequency will have zero values. Filtering this kind of filter with a pitched signal will result in elemination of a pitch frequency and all it’s harmonics, and the filter corresponding to the input frequency will have a minimum output compared to the other filter’s result. Peak2 onset detection works by taking the result of two peak detectors. The first peak detector detects sudden changes in amplitude in time-domain, the second peak detector takes the first peak detector’s values as an input, producing a smother result. Test showed that the result varied between instruments. Onset detection for guitar and piano performs rather poorly, about 55% of all the correct onsets were detected. For pitch estimation, the accuracy for the pitch detected is 81.25% for all monophonic signals and 64.29% for all polyphonic signals.

It’s expected virtual map can be realistic enough. 3d object has been make with AutoCad program for the precision in size. After that, 3dsMax support for give some material in object. It also give some collision, so when user walk around in the bulding it will not be outside from the building.The result from this program is every object shape and position close enough. Time constraints become a major problem from making this program, so some of the details can’t be complete. All of the laboratorium in the 2nd floor already done, but the main stairway in P building 2nd floor and the other minor object haven’t done yet.lack of this program is must use high specification of computer.
