Abstract

Communication is the key to conquering this globalization era. And there is no doubtthat the language is the most important part of communication. One can communicate wellwhen using the same language or understanding the language used to each other.Signlanguage is the language of communication priority manually, body language and lip motion incommunicating. Sign language has been standardized by the name Sibi (Cue SystemIndonesian). Sibi is one of the media in the form of books, can help communication among thedeaf in the community. His form is setting a systematic set of fingers, hands, and othermovements that symbolize Indonesian vocabulary. Media book seems less easily understoodby the user, so the need for an application that is able to provide an image that is moving,making it easier to learn the sign language.Keywords: Communication, Systems cues Indonesian language, Sign Language

Abstract

PT.Inalum is a manufacturing company engaged in the aluminum smelting industry. PT.Inalum pengendaliaan system requires an inventory of spare parts to conduct maintenance, repair and overhaul (MRO). CMMS (Computerized Maintenance Management System) is a computerized maintenance system running on a LAN (Local Area Network). CMMS is influenced by three variables, namely an integrated maintenance, inventory and procurement so as to create a good maintenance should be supported by the inventory control of spare parts used in maintenance. CMMS aims to make the work more efficient and effective, especially in matters relating to maintenance. That as a benchmark to measure the performance of CMMs for spare parts inventory control is a key performance indicator (KPI). This study aims to evaluate and compare key performance indicators before and after implementation of CMMS for the implementation of MRO activities. Another goal to be achieved is to determine the factors that affect the value of the inventory of spare parts. Based on the results of data processing and analysis can be seen that by looking at a comparison of before and after implementation of CMMS on key performance indicators, it appears that there is an improvement in every parameter, one of which is the value of the inventory prior to the implementation of CMMS for $ 34,790,000.00 compared to after the application of the inventory value fell to $ 19,632,000.00. Factors that affect the value of the inventory is the inventory of spare parts, maintenance, procurement, and human resources.

Abstract

Some restaurants are to develop the concept by placing the gazebo-gazebo that were located far apart. With a large area and a place to eat with the amount that more and more the restaurant must provide the waitresses in considerable amounts. Often when the waiter is still busy serving the other guests, then there will be visitors restaurants that can not be served well. In addition, the number of waiters that too many would economically burden the employers because it would result in expenditure will be even greater. Then it can be developed an information system involving hardware and software to apply the reservation system that can be done from the tables or places to eat at a restaurant. Systems built using hardware and software. The hardware is built by using the AVR microcontroller device comprising an IC (Integrated Circuit) which is supported by the power supply, as well as some passive and active components. Software on a microcontroller using C language development tool using CodeVision of AVR. While the computer software using Visual Basic 6.0 programming language. Food ordering system that created it can improve services for consumers in terms of booking. Buyers can make a reservation at the dinner table without going through the waitress who had approached the table and write whatever menu you want to order. Additional bookings can also be done through the table without leaving the place or the waiter.

Abstract

Purpose: This research makes an application to simplify the Boolean function using Quine-McCluskey, because length of the Boolean function complicates the digital circuit, so that it can be simplified by finding other functions that are equivalent and more efficient, making digital circuits easier, and less cost.Design/methodology/approach: The canonical form is Sum-of-Product/Product-of-Sum and is in the form of a file, while the output is in the form of a raw and in the form of a file. Applications can receive the same minterm/maksterm input and do not have to be sequential. The method has been applied by Idempoten, Petrick, Selection Sort, and classification, so that simplification is maximized.Findings/result: As a result, the application can simplify more optimally than previous studies, can receive the same minterm/maksterm input, Product-of-Sum canonical form, and has been verified by simplifying and calculating manually.Originality/value/state of the art: Research that applies the petrick method to applications combined with being able to receive the same minterm/maksterm input has never been done before. The calculation is only up to the intermediate stage of the Quine-McCluskey method or has not been able to receive the same minterm/maksterm input.
