Abstract

Article discusses about the design and implementation of procedural content generation using java, especially the generation of virtual city. It is applied by using L-System to generate the elements of the city and also using some images as the base models. This method is proven to be more effective because it can produce almost unlimited variations of city in short amount of time without any needs to modify the application. The result of this application is a road map which can be used in many areas such as virtual reality, games, or other related purposes.

Abstract

 Light intensity may affect the image quality of an object that can cause barriers in doing preprocessing to improve the image quality of a digital image. Furthermore, this would also be an impact on subsequent processes, such as sorting images according to the needs. Light intensity influences the reflection of light which translates into an image. This gives an impact on successful segmentation process. Examples of the success and failure of segmentation are presented in this paper.

Abstract

Competition is very tight causing companies looking for a competitive edge, both in the product packaging and in maintaining good relations with their customers. The management of good relationship is commonly referred to Customer Relationship Management (CRM). In general, CRM is focused on how to market something to customers and obtain value from them by using information technology. However, it ignores customers’ insight that can provide added value to the company's profits. That is what causes the need for Customer Experience Management (CEM) to handle the experience of customers to improve value for customers so that customers become loyal. More useful definition of CEM is handling customer interactions to build brand equity and increase the long-term profitability. The five-element approach known as SMART (strategy, metrics; alignment, redesign and technology) has a positive impact for the company. In the end customers can actualize themselves, through a company's brand and products.

Abstract

According to Indonesia Association of Service Provider (APJII) survey in 2014, the internet user in Indonesia increased up to around 88 million. This number expresses that the use of the internet to seek business franchise information will increase as well. The increase of internet using should be followed by the quality of franchisor's website. The franchisor's website will relate to system quality, information quality and service quality (DeLone and McLean, 2003). This research uses SEM LISREL to see the loading factors of each indicator impact in variables and website quality variables impact to intention to purchase franchise. The result shows that all variables (System quality, Information Quality, and Service Quality) give significant impact to dependent variable Website Quality.

Abstract

The objective of this research is to develop a web-based expert system for early detection towards characters of investment of people who will invest immediately on their productive ages. The development of this application is encompassing four primary activities in developing an expert system, namely: knowledgeacquisition, knowledge representation, knowledge inferencing, and knowledge transfering. Knowledge acquisition is a process of acquisition or transfering knowledge or expertise of an expert through a knowledge engineer. Knowledge representation is a process of transfering knowledge into a computer based system. Knowledge inferencing is a reasoning process performed by an expert system to draw a conclusion or a final result. The reasoning process applies a forward-chaining method. Knowledge transfering is a process of transfering knowledge from an expert system to a user (non-expert one) through a user interface of the expert system. This expert system has been tested to about 300 users. This simple system generally runs quite well although there are still some weakness to refine in the further research.

Abstract

The development of RFID technology (Radio Frequency Identification) offers some advantages, especially in goods distribution, supply chain and logistics. This technology works by putting a chip on an item as a replacement for barcodes that are widely used today. With the RFID technology, the process of goodsidentification becomes very easy and fast. Therefore, some large companies have started implementing and trust the system, especially the supermarket retailers although there are still some problems encountered in the application of this system, related to issues of privacy and data integrity problems. This paper discusses how RFID works and the impacts to the company related to profits and problems encountered during the application of this system.

Abstract

Padang Karunia Group received a lot of inputs from its employees for improvement collected manually by an administrator. The more input from employees, the more difficult to be collected manually. Therefore Padang Karunia Group took the initiative to create an intranet application to save the inputs in a database. Based on this problem, a research is done to develop database applications in the form of dashboard to collect criticisms and suggestions of employees over the web. This application is expected to assist and facilitate the management of the company, especially in the gathering criticism and suggestions from employees who are then evaluated for company improvement. We uses the database design method based on database application lifecycle, including requirements collection and analysis, conceptual database design, logical database design, DBMS selection, physical database design, and implementation. The results achieved are a database design anda web-based dashboard application that collects criticisms and suggestions. The advantage of using this application is that the company can easily accept criticism and suggestions from employees, simplify storage and data management criticism and suggestions, create reports, and reduce the cost of data collection and the process that was previously done manually. Through the database created, the data management of criticisms and suggestions of employees can be done better.
