<![CDATA[Sistem pemandu museum merupakan salah satu penerapan teknologi informasi (TI) pada museum yang diharapkan dapat membantu pengunjung menelusuri museum. Untuk dapat memberikan informasi yang sesuai, sistem pemandu membutuhkan informasi posisi pengunjung. Informasi posisi tersebut dapat diperoleh dari Sistem Penentuan Posisi (SPP). Teknologi Global Positioning System (GPS) sebagai standar SPP tidak cocok untuk diterapkan untuk lingkungan di dalam ruangan. Oleh sebab itu diperlukan SPP yang khusus bekerja di dalam ruangan. Untuk membangun sebuah SPP yang bekerja sesuai dengan lingkungan museum, diperlukan pemilihan komponen penyusun arsitektur yang berdasarkan pada kebutuhan dan kondisi museum. Studi kasus di Museum Sonobudoyo memberikan hasil bahwa arsitektur yang sesuai sebaiknya menggunakan teknologi WLAN dengan teknik scene analysis berbasis RSSI yang memberikan output berupa informasi posisi absolut.]]>

<![CDATA[The health care system in Libya in recent years does not change significantly, less developed and modernized. This problem is further exacerbated by the revolution that occurred in Libya. The revolution that occurred in 2011 has caused the health care system into collapse. In this study conducted a review for the development of health information systems in Libya by using OpenMRS Framework.At the stage of gathering information using questionnaires concluded that the majority of respondents (about 95.35%) wanted the development of a new system that can resolve the main problems that occurred in Libya, the health information system ineffective and inefficient in which this system has led to wastage of time and increased operating costs. Based on analysis of system vulnerabilities using PIECES method could also be concluded that the current system is not used effectively and efficiently. In this study is also presented on how to implement OpenMRS.Based on the results of the discussion it can be concluded that OpenMRS is a solution that can be taken for the development of a health information system that is fast, low cost, and is an open source application that only requires a little setting in the system of patient management and care. OpenMRS can be implemented to support the health services of a small clinic to the health services with enterprise scale. Therefore, OpenMRS could be the answer to the development of health information systems in various countries around the world, including Libya.]]>

<![CDATA[salah satu area penelitian didunia yang berkembang pesat saat ini adalah IoT, terlebih penelitian pada area berbasis pergerakan atau biasa disebut MANET (Mobile Adhoc Network), hal tersebut tidak terhindarkan lagi karena teknologi ini menjelma menjadi kebutuhan manusia moderen, oleh karena itu tren penelitian selalu mengarah dan mengasumsikan parameter penelitian dan simulasinya pada topologi adhoc. Indonesia dilain pihak belum membutuhkan teknologi semacam ini karena sebagian besar penggunaan perangkat IoT masih berbasis pada topologi infrastruktur tetap/pasti. Paper ini menggunakan Network Simulator 2 (NS2) sebagai perangkat lunak simulasi untuk membandingkan kinerja dari 3 protokol routing terpopuer MANET diantaranya AODV, DSDV dan DSR. Hasil analisa menunjukan AODV menjadi protokol pencarian jalur yang paling dapat diandalkan namun paling boros dalam penggunaan energi.]]>

<![CDATA[The importance of power control feasibility is closely related to the direct implementation of the system, which is related to interference between users in the femtocell network and also related to the optimal use of power transmit that can create a long-lasting battery. Implementation of the feasibility of power control in this study is focused on the centralized femtocell network with a multi-channel user. The research method in this study is based on the use of feasible solution algorithms in power control by observing the output of power vector that should be valued non-negative, which means that it can be implemented. This result indicates that all of user can reach the specified target SINR. SINR users will increase when there are additional channels for user groups. The average power of user will also decrease while increasing the amount of provided channels. The greater number of users in a user group, the less value SINR can be obtained]]>

<![CDATA[Internet of Things or widely known as IOT makes smart objects become active participants in the communication process between objects and their environment. IoT services that utilize Internet connection require solutions to a new problem: security and privacy. Smart objects and machine-to-machine communications in IOT now become interesting research, including that related to security. Privacy, which is a safe condition in which object is free from interference from other objects, is one of the important aspects in IOT. Privacy can be implemented using various ways for examples by applying encryption algorithms, restrictions on access to data or users, as well as implementing rules or specific policy. Trustable object selection is one technique to improve privacy. The process of selecting a trustable object can be done based on past activities or trust history of the object, also by applying a threshold value to determine whether an object is "trusted" or not. Some researchers have studied this approach. In this study, the selection processes of trustable objects are calculated using Modified Ant Colony algorithm. The simulation was performed and resulted in declining graphic trend but stabilized in certain trust value.]]>

<![CDATA[The use of sharing channel simultaneously has become the trend in telecommunication technology particularly in network with distributed users as the allocation of frequency spectrum becomes more crowded. The proposed power control method in cognitive femtocell network is based on game theory (commonly known as power control game, PCG). This method uses utility function formula as the goal of game theory for power strategy in power update process. Utility function formula of Proposed PCG includes channel sharing factor that aimed to accommodate the system requirement of channel sharing. The result showed that the implementation of channel factor is inversely proportional to the signal to noise and interference ratio (SINR) and transmit power, but proportional to utility function. In comparison of user transmit power and SINR with two other methods, can also be conclude that Proposed PCG was able to achieve SINR of 5.49 dB and above the SINR target 5 dB, while the Thalabani (TB) and Koskie-Gajic (KG) were only able to achieve respective SINR of 4.87 dB and 4.98 dB. It can be concluded that the Proposed PCG was better in achieving the SINR target. It means that the quality of service in this system can be fulfilled properly.]]>
