Abstract

Besides having a particular function or purpose, a building also has certain characters that generally appear and are accumulated into an image or impression given by anyone who sees the building. Function is a fundamental starting point for all architectural expression. The influence of function on the architecture is quiteobvious especially when we observe differences in the use of certain building and how certain activities can create the form of the building. However, is it true that the function and form of the building has any relation with the formation of building classification (typology)? For that reason, this paper discusses a case study ofmosque buildings.

Abstract

Sometimes we find difficulties in obtaining the necessary information as limited to place and time, as well as the media used. One example is limitations in obtaining the necessary information about facilities available at the nearby of Binus University campus. Based on this case, we propose information media providing facilities around Binus University campus that can be accessed anytime and anywhere using mobile web technology guided by Google maps. The features of Google maps can also help users locate the facility. The methodology used in this research is analysis and design. Results that can be obtained from this research is a mobile-web application that provides complete information about the environment around BINUS campus that can be accessed by students and the surrounding community. Using this application, BINUS students can obtain the necessary information about the campus environment easily and quickly.

Abstract

Research in the affective game has received attention from the research communities over this lustrum. As a crucial aspect of a game, emotions play an important role in user experience as well as to emphasize the user’s emotions state on game design. This will improve the user’s interactivity while they playing the game. This research aims to discuss and analyze whether emotions can replace traditional user game inputs (keyboard, mouse, and others). The methodology used in this research is divided into two main phases: game design and facial expression recognition. The results of this research indicate that users preferred to use a traditional input such as mouse. Moreover, user’s interactivities with game are still slightly low. However, this is a great opportunity for researchers in affective game with a more interactive game play as well as rich and complex story. Hopefully this will improve the user affective state and emotions in game. The results of this research imply that happy emotion obtains 78% of detection, meanwhile the anger emotion has the lowest detection of 44.4%. Moreover, users prefer mouse and FER (face expression recognition) as the best input for this game.

Abstract

This study discusses specifically the encryption mechanism that maintains the integrity of the game data on online games. The purpose of this study is to implement symmetric key encryption and checksum for score calculation. There are two methods conducted in this study: analysis and design. The analysis method isperformed in two ways: analysis of existing systems and analysis of literature study. System design method used is prototyping. The results obtained are implemented on online game competition ‘Expedisi Indosat’ through Facebook from 3 – 30 July 2011. The implementation of symmetric key encryption mechanism and the checksum is useful to maintain data integrity on games especially the results score when the game is running and when there is data transmission from the client to the server.

Abstract

Puskemas as community health centers becomes one of the main focuses of development on the agenda of the Government of Indonesia beside education. Therefore, we purpose to develop an affordable online system of health care administration based on open source using cloud computing approach. It can be used for collecting data of patients, diseases, and treatment of patients at Puskesmas. The methods used are literature study related to cloud computing, survey design and data collection infrastructure of information technology thatcan be applied to online health services, analysis of survey data on actual conditions in some centers and other health care centers in Jakarta, then making model of online health services such as physician consulting, prescribing and disease diagnosis. The result is a web-based application system of health care administration of Puskesmas, which utilizes cloud computing technology and development architectures that are both modular and dynamic. The application model combines the benefits of open-source applications with a flexible design system. It also supports mobile devices to improve the quality of patient care. Web-based network structure allows both online and inter-section between institutions which can be accessed anytime, anywhere, through mobile devices.Development application model is also adapted to the function of the business processes and administrative processes that exist in Puskesmas throughout Indonesia. Each model is also expected to be integrated to optimize efficiency and has been adapted to the service system of Dinas Kesehatan and Health Ministery.

Abstract

Basically, when waves pass an uneven basis, then this wave will be split into transmission and reflection waves. First of all, it will be shown that a sinusoidal seabed can lead to the phenomenon of Bragg resonance. Bragg resonance occurs when the wave-length comes at twice the wave-length of a sinusoidal basis. The method used to obtain approximation solution is a multi-scale asymptotic expansion method. A research on the effect of Bragg resonance on sinusoidal basis had been studied. Sinusoidal basis can reduce the amplitude of the incoming wave so that the amplitude of the wave transmission is quite small. In these researcher, the coast is assumed ideal and can absorb all the energy of the wave transmission. If the beach can reflect waves, this indicates that the existence of sinusoidal basis is more harmful to the coast. This mechanism relies on the distance between the base sinusoidal and beaches. The present research will examined the influence of the base, when there was a beach of hard-wall on the right, which was perfectly capable of reflecting waves. Having regard to the phase difference, from super positioned waves when they hit the beach, so it can determine the safert and the most dangerous distance.

Abstract

The lack of green computing governance model for environment of universities in Indonesia becomes one major factor to conduct this research. In fact, the teaching and learning activities in campuses depend on support of information system and information technology. Various studies on green computing were observed. However, the suitable model for green computing in the area of private university Indonesia has not been observed yet. Referring to Green ICT Framework by University of Michigan and Connection Research as well as green computing framework by Adcuent, the green computing model for private university in Indonesia was developed through this research. Although the research object was observed in Bina Nusantara University, Jakarta, Indonesia, it is adoptable for other private universities to evaluate their information system and information technology performance surround campuses. Green computing governance is part of information system and information technology strategic plan. Therefore, the management of university should fully concern towards this matter.
