General expert system is a system that tried to adopt human knowledge to computer, so that the computer can solve the problem as was done by experts. Or in other words the expert system is a system designed and implemented with assisted of a particular programming language to be able to solve problems like that done by experts. Hopefully this system, common people can solve a particular problem either 'a little' tricky or complicated even 'without the' assistance of experts in that field. As for the experts, this system can be used as an experienced assistant. Applications developed is aimed to determine the type of disorder in children from age 0 years with the only symptom noticed symptoms. By using Certanty Factor (CF), to obtain the likely disruption experienced by the patient. © 2016 IEEE.

CobiT4 provide a framework to evaluate the performance of IT management by using some control objective, method and standard maturity measurement [1]. Assessing maturity level is usually a first step to start audit process in an organization. Maturity Level adjustment can be a significant input to improve the process. CobiT4 has provide some maturity level characteristic for assess the existing condition in an organization, but in facts, there were some constraints to map existing condition into one exact score of maturity level measurement. Pederiva[2] proposed some approach to modify the maturity level measurement method which is more realistic approach for mapping the existing condition to some maturity level characteristics. The modified method for maturity level assessment then implemented on audit process at PT.Pos Indonesia using CobiT4 Framework. During the audit process, site visit, interview and questionarrie were using to collect data directly from all stakeholders. The scope of audit was limited into one control objective from CobiT4 framework, AI1, Identify Automated Solution. The audit results provide more realistic score for maturity level adjustment which are derived from fact finding and can express some real existing condition. Analysis from fact finding also can give some recommendation for improve IT resource management, especially on AI1 Control Objective scope. © 2010 IEEE.

The Assignment Problem is very interesting to be researched because it is simple but wide in the applications. Hungarian Method, developed by Harold Kuhn in 1955, is one of the most popular algorithms to solve the assignment problem since it is easy and practical. However, its easiness is restricting the form of iteration process which is quite complicated. A research about the effective and efficient new algorithm is needed. In this paper, we introduce a new concept for solving the assignment problem. The Interaction Theory has been developed since 1966. We developed the coefficient interaction formula and succeeded to be implemented to solving the hard problems in the exact way and giving more alternative optimal solutions with the same value. The algorithm is introduced in this paper along with several applications; including problem with more than one solution, unbalanced problem, and problem with incomplete data. The Interaction Theory gives a new hope as a new paradigm. The algorithm is simple yet effective and efficient to solve all kinds of assignment problems such as unbalanced assignment problem, and minimize and maximize objective. Moreover, the algorithm sometimes produces more than one optimal solution. © 2014 IEEE.

Higher education sector is increasingly facing competition from both domestic and international providers. In anticipating this condition higher education institutions have shown an increasing interest in the adoption of a marketing relationship within the sector to create, maintaining and enhance strong relationship with their students to ensure their loyalty. The objective of this study is to investigate the relationship between the components of relationship marketing and student loyalty. A survey was conducted to collect data through a questionnaire containing 23 items that was completed by 400 randomly selected students and multiple regression analysis was used for data analysis. The results revealed that the all underpinnings of relationship marketing were directly associated with student loyalty and they had a significant effect on it. Therefore it is reasonable to conclude that student loyalty can be created, reinforced and retained by relationship marketing strategy. © 2015 American Scientific Publishers.

This paper aims to propose a framework for assessing information system (IS) success considering the impact of culture. Previous frameworks for assessing information system (IS) success, such as DeLone and McLean model, only concern about the status of IS implementation itself. But none of the models have included the dimensions for assessing culture even though researchers have shown the strong relationship between culture and the success (or failure) of the IS. The inclusion of culture in the IS success model is very important, especially in Indonesia, since culture plays as a dominant part in almost all aspects of citizen's lives. This paper is expected to make a contribution on providing a framework for assessing IS success considering the impact of culture. To validate the proposed model, a mixed-method research design is proposed. © 2014 IEEE.

The implementation of GIS based application is growing rapidly in many areas such as business, government, or public services. Potential implementation of a GIS-based application then applied to the mapping of conditions and irrigation building and canal. The application will display the latest information on the condition of each building irrigation in Rentang area, covering three districts namely Majalengka, Cirebon and Indramayu. This area has about 1000 buildings irrigation and segment that connects between buildings. In order to present the interactive map and running in a web environment, the map should be processed using a series of stages of preparation of maps using GIS software such as ArcGIS, Quantum GIS, PosgreSQL and PostGIS, GeoServer, and OpenLayers. The resulting map is then divided into three main layers based on category object to be displayed, that is the main irrigation channel, secondary channel and tapping buildings. Users can see the position and condition of each object which is represented by a different color for each condition: green for good conditions, yellow for minor damage and red for major damage. This application is expected to help the units involved in obtaining a general overview of irrigation in certain areas quickly and accurately. © 2014 IEEE.

The number of people using online tablets in public places has increased dramatically. Their postures are dominantly characterized by non-neutral and awkward positions that in the long term may lead to a higher risk of musculoskeletal disorders. The purpose of this study was to investigate the effects of tablet compared to laptop (i.e. netbook) usage postures on the development of fatigue, discomfort and pain. A total of 12 participants accomplished email typing tasks for 2 hours with four different usage configurations: 1) Netbook-on-table, 2) Netbook-on-lap, 3) Tablet-on-table, and 4) Tablet-on-lap. Changes in fatigue, discomfort, and pain were monitored based on pinch grip strength (tip pinch, key pinch, and palmar pinch), rating of perceived discomfort, and Phalen’s & Reverse Phalen’s tests, respectively. The results indicated that the effect of portable device placement was significant (p < 0.05), with varied effects across measurements. No effect of portable computer type was found. The interactive effect of portable computer type and placement was only significant for right tip pinch (p < 0.05). The findings of this study can hopefully be used to increase the awareness of tablet users about associated fatigue, discomfort and pain while using a tablet in public places that may lead to a higher risk of musculoskeletal disorders. © 2016 Published by ITB Journal Publisher.

The development of 'e-something' takes place in almost all government sector, include Indonesian Government. One of electronic-based system developed recently in Indonesia is e-procurement system. This condition brings much higher financial requirement and qualified human resources to build the IT infrastructure. We proposed cloud computing scheme architecture for e-procurement system in Indonesia (Jawa Barat) to reduce the IT cost for implementing the e-procurement system. The ROI analysis is carried out to select which cloud scheme is best to apply in Indonesia's condition. We also propose the architecture of the new cloud-based system based on the analysis conducted. The analysis result show that a significant cost reduction is achieved by implementing infrastructure as a service scheme cloud computing in e-procurement system at Jawa Barat Indonesia. For cloud implementation, we choose to use Amazon S3 due to its high durability and it complements with e-procurement organisation requirement to move only management data to the cloud.

Environmental aspect is often neglected in traditional distribution planning process of a product. Especially in small-medium enterprises (SME) of developing countries where cost efficiency is the predominant factor. Bearing in mind that there is a large number of SME's performing logistics activities, the consideration of environmental aspect in their distribution planning process would be beneficial to climate change mitigation efforts. The purpose of this paper is to show the impact of environmental aspect should it be considered as a contributing factor in distribution planning. In this research, an adoption of CO2-emission factor in an SME's distribution planning in Indonesia was simulated. The outputs of distribution planning with and without the factor consideration are then compared. The result shows that adoption of CO2-emission factor would change the priority of delivery route.
