Informasi tentang model yang sedang berada di line produksi PT Sanken Indonesia sangat dibutuhkan untuk mengoptimalkan kinerja personil bagian kontrol kualitas. Pada tugas akhir ini dilakukan rancang bangun papan informasi elektronik yang sesuai dengan kebutuhan dan memenuhi keterbatasan PT Sanken Indonesia. Papan informasi elektronik terdiri dari ATMega8535 sebagai pengolah dan peyimpan data, LCD untuk tampilan informasi tulisan bagi operator, power supply, dot matrix display serta melibatkan PS2 keyboard untuk memasukkan data. Dot matrix sebagai perangkat display dapat menampilkan tulisan bergeser dengan kriteria kecepatan looping 3.06s dan setiap karakter dapat dimunculkan dengan selang waktu sekitar 95ms. Perangkat ini juga mampu menyimpan data kendati terjadi hubungan putus listrik.

Information about models which are running on the production line of PT. Sanken Indonesia is needed to optimize the performance of quality control personnel. In this project an electronic information board design for special purpose that suits the needs and meet the limitations of PT. Sanken Indonesia is conducted. Electronic information board is consist of ATMega8535 as data processing and storage, LCD to display text information for operators, power supply, dot matrix display and involves PS2 keyboard to enter data. Dot matrix display device can display the article shifts with speed loops 3,06s and each character can be raised at intervals of about 95ms. This device is also capable of storing data occurred despite broken electrical connection.

Pada skripsl ini dibuat perangkat pengganti keyboard dengan menggunakan pesawat telepon sebagai bagian dari sistem minimum komputer untuk melakukan hubungan dengan intemet. Perangkat ini dirancang agar dapat menghasilkan fasilitas - fasilitas tertentu yang sering digunakan dalam keyboard, seperti huruf, backspace, space bar dan enter. Dan juga dirancang agar pemakaian pesawat telepon untuk melakukan komunikasi biasa tidak terganggu. Untuk mengaktifkan perangkat ini digunakan kode tombol tertentu (tombol fungsi). Sebagai sinyal informasi digunakan sinyal DTMF dan unit antar muka pada perangkat ini adalah PPI 8255. Dari hasil uji coba yang dilakukan, perangkat ini dapat mendeteksi adanya panggilan yang masuk, serta dapat mencegah pengiriman sinyal DTMF dari pesawat telepon Iangsung ke sentral dan juga dapat mendeteksi apakah pengguna ingin melakukan hubungan intemet atau hubungan pembicaraan biasa. ...... In this script, a keyboard replacement device is created using a telephone as part of a minimum computer system to connect to the internet. This device is designed to be able to produce certain facilities that are often used in the keyboard, such as letters, backspace, space bar and enter. And also designed so that the use of the telephone to make regular communication is not disturbed. To activate this device, a certain button code (function button) is used. As an information signal, the DTMF signal is used and the interface unit on this device is PPI 8255. From the results of the trials carried out, this device can detect incoming calls, and can prevent the sending of DTMF signals from the telephone directly to the exchange and can also detect whether the user wants to make an internet connection or a regular conversation connection.

ABSTRACT
The use of smartphones and handheld devices in our daily activities has sharply increased. The added features of wireless technology and related applications on these devices make it possible to write emails, notes, and long text. Even though the most commonly used electronic input device is a keyboard, very little work has been dedicated for finding an optimal layout for this device. In this research, the aim is to propose a better layout for the single-finger keyboard in terms of rapid typing. The keyboard layout problem can be formulated as a quadratic assignment problem, which is one of the hardest combinatorial optimization problems. Some well-known literary works in English are chosen for estimating the keying-in-time. A variant of genetic algorithm, namely, the estimation of distribution algorithms is used to find a better layout. The new layout is found to be efficient compared with some of the existing prominent keyboard layouts.
