Abstract

WiFi Protected Setup (WPS) is a standardized function supported by numerous vendors of wireless routers and access point to help set up connection to a wireless local area network. It is designed to simplify the set up and generally enabled by default. Due to design flaw, the WPS or QSS PIN is susceptible to a brute forceattack. In this paper, we test the security vulnerability occurred, evaluate the performance and give recommendations to anticipate the attack.

Abstract

Basically the use of integrated information systems can be applied not only for the company, but also education industry, particularly schools. To support business processes at the school, this research would like to describe a conceptual model of information systems using the Unified Modeling Language (UML) notationwith "4 +1 View" architectural model. This model is expected to assist analysis and design the whole business processes at school. A conceptual model of the information system can help application developers to easily and clearly understand the school system. By adopting this information system model, schools are able to have effective understanding of management information systems.

Abstract

Topography is the science about the earth's surface and other objects such as planets, satellites, and asteroids. Topography is studied at school and is found quite difficult to understand because it requires imagination to understand the meaning of contour maps as well as the lines. To motivate students in learning topography,we design an learning application of interactive topographic map with 3D features using Augmented reality technology. In this research we implement analysis and design method. The result achieved is a learning topographic map application based on augmented reality. The conclusion that can be drawn is the teaching and learning of topography can be more interesting with 3D features so that students can more easily recognize the meaning of contour lines in a topographic map.

Abstract

Data is a very important asset for a company since it describes the company’s running processes. Database as a part of the information system components provides a big influence in helping data integration in a company. Therefore, we need a system which can facilitate the availability of data to be processed and used as needed, This study takes a company engaged in the sale of bike and spare parts, namely PT TDI, as the object of the study. At this time, PT TDI uses an integrated system in helping the company's operations. Along with the vision and mission, PT TDI intends to build a new operating system by applying the concept of Customer Relationship Management (CRM) which is believed to assist the company in maintaining relationships with customers using web-based platform. It aims to facilitate interaction with customers so that it can be done anytime and anywhere. This study implements the database design life cycle adjusted to the component aspects of CRM. The result achieved is a model that combines database CRM systems that can help companies improve relationships with customers.

Abstract

Internet network which is public and global is unsafe, so the security of public Internet-based information system needs to be considered. When a data is sent from one computer to another on the Internet, it will pass through a number of other computers that are meant to give the user an opportunity to take over one or several computers. denial of service attacks is one of the web security systems which can inhibit the activity of the work of a service even turn it off, so the authorized user cannot use the service. There is an attempt of certain parties to prevent a user access to a system or network by flooding the traffic network with so much data from unregistered users. It makes the user unable to log into the network system. The purpose of this paper is to analyze the cause of the denial of service attack on a web system using literature study. The result of this research is a method to overcome denial of service attack as well as the prevention techniques. This study concludes that securing techniques should be implemented extra carefully on DoS attacks (Denial-of-Service Attacks). Therefore, the attacker cannot overwhelm the network IP address and disrupt communication between a server and its client that may reject user’s request access to a system or a network service provided by a host.

Abstract

Regarding to: (1) the increasing region’s need in developing tourism destinations; (2) the needs of tourists in selecting appropriate attractions according to specified criteria; (3) the need of travel businesses to offer sights of interest in accordance with the needs of potential tourists, (4) the need to deepen and continue our previous research titled "Development of Tourism Destination Media Potential and Utilizing Local Resources in the Era of Autonomy and Regional Expansion ", we need to develop a complete database of tourism destinations in Indonesia that can facilitate those needs. We build a web-based database that is capable of storing complete information about Indonesian tourism destinations in thorough, systematic, and structured way. It is also able to classify a variety of attractions based on attributes such as: location (the name of the island, province, district), type/ tourism products, how to achieve the object, cost, and a variety of informal information, such as the ins and outs of the attraction area incorporated by the local or tourist experiences. The research will focus on deepening and refinement of the model and database structure design and implementation with the collection, processing, and data entry of primary and secondary data which amounts to approximately 140 tourism destinations in Indonesia. The research is arranged in stages as follows: (1) designing models and the database structure, (2) making a web-based program, (3) installation and hosting ; (4) data collection, (5) data processing and data entry, (6) evaluation and improvement/ refinement. Once developed, the database can be used as a starting point in the development of Data Warehouse, Decision Support System, and Expert System for Indonesian tourism industry.

Abstract

Contribution of MSMEs (micro, small and medium enterprises) in the economy is significant enough. It indicates the importance of support for MSMEs to maintain and double the capacity their businesses. In conducting its business, 76% of respondents already use the Internet (e-business) but still not optimally because the average does not have a website as a forum for the promotion and selling activity. Total mean score of 4.2 in adoption of innovations indicates that it has been realized, done, evaluated and adopted as a whole. Therefore, it is necessary to perform an assessment on what extent of e-business application that has been done by reviewing the readiness of MSME industries and the aspects of the utilization of information and communication technology (ICT) by MSMEs particularly of those located in Jabodetabek. The purpose of this assessment is to get an overview, status and position of the support of implementation of e-business owned and how the adoption process of e-business application can run in Jabodetabek. With the assessment of e-business technology use, we expect the planning, implementation and control of programs as well as the implementation of e-business can be conducted more directedly and controlled.
