Abstract

The increasing competition in hotel business forces every hotel to be equiped with analysis tools that can maximize its marketing performance. This paper discusses the development of a data warehouse model and analytic tools to enhance the company's competitive advantage through the utilization of a variety of data, information and knowledge held by the company as a raw material in the decision making process. A study is done at ABC Hotel which uses a database to save the transactional record. However, the database cannot be directly used to support analysis and decision making process. Based on this issue, the company needs a data warehouse model and analytic tools that can be used to store large amounts of data and also potentially to gain a new perspective of data distribution which allows to provide reporting and answers of ad hoc users questions and assist managers in making decisions. Further data warehouse model and analytic tools can be used to help manager to formulate planning and marketing strategies. Data are collected through interviews and literature study, followed by data analysis to analyze business processes, to identify the problems and the information to support analysis process. Furthermore, data warehouse is designed using analysis of records related to the activities in hotel's marketing area and data warehouse model. The result of this paper is data warehouse model and analytic tools to analyze the external and transactional data and to support decision making process in marketing area.

Abstract

Management of employees as a resource is essential to enhance the effectiveness of employee’s performance, and the process efficiency of for organizations or companies. Possible problems related to the management of human resources need to be diagnosed which one to be solved as a priority. The problem is how to design the decision making model to help the Human Resource Department in determining the criteria for recruitment which can be used to take decisions on recruitment of human resources. This research aims to design a model of decision making systems and databases to support accuracy of decision making in human resource information system to create high loyalty and productivity so that the productivity of the company can be further improved. The research is divided into two phases: collection as well as analysis of data and design model. Specifically target to be achieved in this research are to identify the critical success factors of the model of decision making system for recruitment and develop models of decision-making system. The results obtained from this research are hierarchical decision models using analytical hierarchy process and its database design for the recruitment sub-system of human resource.

Abstract

At certain moments, especially on national holiday transportation users greatly increase. The manual ticket booking system of inter-city buses is not very effective and efficient as indicated that it takes long time to book tickets and find information about ticket availability for a specific purpose on a certain day. Besides, inaccuracies often happen on synchronizing ticket availability with seat availability. Due to those problems, it needs to be made a model of ticketing information system of inter-city buses. The initial phase focused on booking tickets at a branch office. The next stage of development is integrating the  information system of all branch offices to the central office. The purpose of this paper is to create a model of the system design if inter-city bus ticket reservation in inter-provincial branches can provide convenience for the branch to book tickets booked by customers. The methodology used in this research is a preliminary study by library research, followed by analysis on running systems through survey findings, then identification of information needs. From the results of this study it is found that a more specific design and implementation are expected to be made so as to provide more benefits to its users. The results of this study can be further developed and integrated with the central office.

Abstract

The ability of Indonesian computer practitioners in making business applications programs which are both internet-based and non-internet-based is already satisfactory. Their work can be viewed from a variety of business applications commissioned by many local, national and international levels. The problem often encountered is the lack of project management at the company maker of project business applications. It may affect the availability of adequate documentation as part of the project output. In this paper the author recommends software developing using a concept by McConnell (1996) that depends on the project’s characteristics and scope. McConnell is one of the mainstays of Microsoft experts who experiences many years as a project leader software made by the company. The object of this paper is to study several beginner companies of software developer in Jakarta. The software coverage is especially for profit company and both internet-based and non internet-based applications. From a comparison of several projects it is found that that late delivery often occur since the methid is implemented less stringent. This study is expected to be useful for other novice developers who get difficulty in submission software on time, right cost and right quality at the scope of the software that has been agreed.
