Abstract

Many ways are taken to be superior in the existing competition, such as differentiation products, identifing new marketing strategies, and improving the performance of operational activities in order to obtain positive responses from the customer. The role of the customer in the implementation of a trading company holds an important position because of all the activities carried out focus on how companies can build satisfaction for the customer, so that in the future they will be back to the company'. This research discusses the design of an information systems to support the implementation of the company's daily operation which consists of selling activities, purchasing, and stock. The method used consists of analysis and design. Analysis begins from the identification of operational processes and data used in daily trading company in general, equipped with some concepts from supporting research literature to develop a model that can be applied. Meanhile the design method through the object oriented approach are illustrated using diagrams Unified Modelling Language (UML). A conceptual model of information system that can be implemented in support of the company's trading operations, which can provide competitive advantage for the company to face competition in the industry.

Abstract

The objective of this study is to develop an online application of mortgage loan simulation. This application is developed based on a web application in order to be accessible anywhere and anytime. This application is expected to help prospective property’s consumers calculate their financial plans related to decisions concerning the amount of down payment, loan term, and the mortgage system model to be selected. There are two models of mortgage in this application. The first is a fixed and cap rate of interest, with the first three years of the mortgage interest rate of 9.75%, the fourth and fifth year interest of 10%, and the sixth year onwards using a rate cap interest with the indication of 12%. The second model is a 2-year fixed rate mortgage with the first two years rate of 8.5% and the third year onwards using adjustable rate mortgage of interest with the indication of 12%. Calculation formula and the interest rates in this application are obtained from Bank XYZ which is in turn applied in collaboration with financial portal www.kontan.co.id. This application has been tested by over 1000 users and the results are well proven and valid.

Abstract

PT Argatama Multy Agung is one provider of metal cutting services using turret machine. The quality of metal cutting services offered are still questioned. The quality service intended is that the length accuracy of the outcome product meets the requirements of the requested length. The purpose of this study is to determine what factors lead to defects the goods length, as well as to provide the right solution that factors can be eliminated so that the number of defective products can be reduced. In this research authors implement Six Sigma methodology with an improved model of Define-Measure-Analyze-Improve-Control (DMAIC) to perform improvement in the services quality provided by PT Argatama Multy Agung. On the improvement phase Design Of Experiment (DOE) is used to find the machine configuration that can produce the best quality. From the research conducted, a significant increase of sigma is obtained.

Abstract

The aim of this research is to design a database model which is conceptual and logical for a 24-hour clinic. The methods used in this research are the data collection through literature studies, surveys, and interviews to the clinic management to get a description of the business processes implemented at a 24-hour clinic. Then we use the conceptual database design method which identifies important entities, relationships entities, and existing attributes. After that, we create a database logical model which represents the clinical database 24 hours. From that, the model is expected to be a logical database model for further development into a clinical application 24 hours to improve the health services to the public.

Abstract

The aim of this research is to study and introduce fuzzy logic into audit information system. Fuzzy logic is already adopted in other field of study. It helps decision process that incorporates subjective information and transforms it to scientific objective information which is more accepted. This research implements simulation scenario to see how fuzzy logic concept should be used in audit information process. The result shows that there is a possible concept of fuzzy logic that can be used for helping auditor in making objective decision in audit information system process. More researches needed to further explore the fuzzy logic concept such as creating the system of fuzzy logic and build application that can be used for daily information system audit process.
