Abstract

The activities currently carried out in searching for book catalog data are less effective because the method used is still conventional. The string matching algorithm is a solution for making book catalog application search engines to be more accurate and faster when performing data searches. There are several string matching algorithms including the Knuth-Morris-Pratt and Boyer Moore algorithms which are the most effective in performing string matching in the case of book catalogs, for that we need a comparison analysis of the Knuth-Morris-Pratt and Boyer Moore algorithms using the Exponential Comparison Method to determine the algorithm. which are suitable. From the results of the comparisons made, it can be concluded that the Boyer Moore algorithm is faster and more accurate. Keywords: Application, Knuth-Morris-Pratt, Boyer Moore

Abstract

At this time in the labeling section of PT. Jotun Indonesia often makes mistakes in conveying information to the filling section about can products that have been labeled, because in recording the list of products that have been labeled that are still labeled using manual methods, namely by writing on a whiteboard, of course, this method is less effective. Therefore an application is needed to find out which product can lists are already labeled so as to facilitate the labeling operator in effectively informing labeled product cans to the filling operators. The purpose of this research is to find out ways for labeling operators to input QR code labels automatically and to find out ways for labeling operators to inform the filling list of products that have been labeled to the filling operators effectively so as not to inhibit the filling process, and target filling per day is still achieved . The research method used is descriptive in nature with the OOP (Object Orientied Programming) approach while the system development method for android-based applications uses the prototype method. Making software in this thesis, the author uses PHP Framework Codeigniter, Sublime Text 3, Android Studio, and for the database using PhpMyAdmin. The result of making this application is to be able to check the status of the product list list of products that have been labeled via an android smartphone, by scanning the QR code in the box that contains the product can that has been labeled using the system application. Testing of this application uses blackbox testing. This research shows that the application of goods inventory system using Android-based QR code scanner can facilitate the labeling operator to input QR code label identity data automatically, helping to facilitate the labeling operator to convey labeled product list information to label operators effectively. Keywords : Aplikasi, Inventory, QR Code Scanner, Android.

Abstract

The problem of data processing is still done manually using MS. Excel and paper media, so that the impact resulted in a lot of data accumulation and errors in data processing of the stock inventory system at PT. Shinheung Indonesia, the implementation of the stock inventory system was able to provide data according to the execution of transactions in each department. Expenditure of stock of goods in the area of each department where data is input manually which includes, input stock, request for goods, output stock, balancing actual stock. This study aims to optimize the inventory of goods accurately and create a stock inventory system of PT. Shinheung Indonesia to make data processing more effective and efficient. The company or department is easier to process and control the existing stock. This system uses an object oriented programming development method, namely the Laravel framework. The information system design uses the programming languages PHP, mysql, xampp, sublimeText3, Gitbash. This study only discusses the inventory system carried out in the MC (Material Control) department of PT. Shinheung Indonesia Research that optimizes inventory in real time and minimizes errors in input output, so that all departments can access goods data when transacting.

Abstract

According to data from internetworldstats, internet users in Indonesia are the third largest in Asia, reaching 212.35 million in March. However, with the increasing number of internet users in Indonesia, there are still many data leaks, especially in terms of website security. Wordpress is one of the most popular CMS in the world, so it is very likely that there are security vulnerabilities. In this study the author will implement a notification system using the whatsapp gateway every time there is a login to the system. The implemented system turns out to be running well and can increase security in monitoring web logins on the wordpress system. Keywords: content management system (CMS), security, notification, whtasapp gateway.

Abstract

The existence of gas turbines has an important role in generating energy, this tool utilizes gas and oil fuels to produce energy that is ready for use. Gas turbines continue to experience modifications and developments from year to year so that they can be used effectively and efficiently in their operation. Various technologies are developed to be able to generate electrical energy to the maximum by modifying and combining one working principle with other work principles. Whatever the facts are as sophisticated as any technology that is developed still has weaknesses and shortcomings so it requires more time to be able to produce a quality product. Therefore we need a process of innovation and problem solving in order to overcome this problem by providing alternative solutions to the shortcomings that exist so that the technology used can generate various benefits and minimize the risk of loss. In this report there are several alternative solutions for technology and generator components that are expected to provide little input and solutions so that among some of the shortcomings can be minimized. Keywords: Gas turbines, electrical energy, energy generation technology, gas and petroleum, alternative solutions
