<![CDATA[Wireless Sensor Network (WSN) has limited energy characteristics so that the proper configuration is needed in order to create the WSN has a low energy consumption to extend the WSN’s life time. By utilizing the collision incident which is difficult to avoid while nodes transmit data packets so that it can reduce the network’s performance, and then makes it as an active - sleep scheduling that can improve the energy efficiency of WSN. So in this study, we proposed an Ant Colony Optimization (ACO) based routing protocol with collision based MAC 802.11 which will be compared with ACO based routing protocol with MAC 802.11 on WSN in terms of energy efficiency. The results obtained from the simulation carried out is that WSN on the grid topology with the small number of nodes (12 nodes) that using an ACO routing protocol with MAC 802.11 collision based has increased energy efficiency by 91.7% while with the large number of nodes (70 nodes) has increased energy efficiency by 81.4%.]]>

<![CDATA[Large parking area and no sign, will make it difficult for vehicle owners to remember and find the location of the parked. Therefore, a guide system becomes one of the important things in a large parking area. The technology that can be utilized in navigation systems is bluetooth technology, which has now called BLE (Bluetooth Low Energy) with a signal reach of 100 meters, data transfer speeds 1 Mbps and low power consumption. The information from a BLE module is the value of RSSI (Received Signal Strength Indicator) which shows the signal strength received. The guide system installed on a smartphone as a receiver and BLE module as a transmitter on the vehicle. The mobile application will convert the RSSI into the distance between smartphone and vehicle, and will be displayed a guide to the vehicle. Based on the trials that have been carried out obtained an average distance error of 0.92 meters, this is due to the ups and downs of the RSSI value received. When the RSSI value received is small, it raises of accuracy. So the distance between BLE and receiver will affect the RSSI value received and affect the position accuracy of the application.]]>

<![CDATA[Medical imaging is a presentment of human organ parts. Medical imaging is saved on a film; therefore, it needs a big saving quota. Compressing is a process to remove redundancy from a piece of information without reducing its quality. This study recommended compressed medical image with DWT (Discrete Wavelet Transform) with adaptive threshold added and entropy copying with the Run Length Encoding (RLE) coding. This study is comparing several parameters, such as compressed ratio and compressed image file size, and PSNR (Peak Signal to Noise Ratio) for analyzing the quality of reconstructive image. The study showed that the comparison of rate, compressed ratio, and PSNR tracing of Haar and Daubechies doesn’t have a significant difference. Comparison of rate, compressed ratio, and PSNR tracing on the hard and soft threshold is the rate of the sold threshold is lower than the hard threshold. The optimal outcome of this study is to use a soft threshold.]]>

<![CDATA[The high reliability of data access has become a problem faced by many companies, institutions, and universities. For this reason, a protocol required that can protect the network from a communication breakdown. One method used to maintain communication is by implementing a protocol redundancy system. One or more routers will act as the primary router for load balancing, and some routers are in standby mode if one main router is down. First hop redundancy protocols (FHRP) is a protocol that implements redundancy and load balancing systems. This protocol can transfer access data traffic if one of the routers on the network is down. FHRP divided into virtual router redundancy protocol (VRRP) and gateway load balancing Protocol (GLBP). This research analyzes the design and implementation to provide information about the quality of VRRP and GLBP services on the main router and the backup router, by using an application graphical network simulator (GNS) simulation 3. In the GNS3 application, a LAN network topology is designed with eight router devices in the form of a ring topology using RIPv2 and OSPF routing protocols, then implemented in protocols VRRP and GLBP. The analysis results show that GLBP can back up the network faster than VRRP when the primary router is down. If implemented into a LAN network with RIPv2 and OSPF routing protocols, VRRP has better service quality than GLBP.]]>

<![CDATA[The quality of students can be seen from the academic achievements, which are evidence of the efforts made by students. Student academic achievement is evaluated at the end of each semester to determine the learning outcomes that have been achieved. If a student cannot meet certain academic criteria that are stated by fulfilling the requirements to continue his studies, the student may have the potential to not graduate on time or even Drop Out (DO). The high number of students who do not graduate on time or DO in higher education institutions can be minimized by detecting students who are at risk in the early stages of education and is supported by making policies that can direct students to complete their education. Also, if the time for completion of student studies can be predicted then the handling of students will be more effective. One technique for making predictions that can be used is data mining techniques. Therefore, in this study, the Naive Bayes Classifier (NBC) algorithm will be used to predict student graduation at Telkom University. The dataset was obtained from the Information Systems Directorate (SISFO), Telkom University which contained 4000 instance data. The results of this study prove that NBC was successfully implemented to predict student graduation. Prediction of the graduation of these students is able to produce an accuracy of 73,725%, precision 0.742, recall 0.736 and F-measure of 0.735.]]>

<![CDATA[Wireless sensor networks (WSNs) are small devices that are run by batteries as minimal energy resources. The cluster method is one of the ways on WSN that is widely applied to the routing protocols to extend the network's lifespan. Low-Energy Adaptive Clustering Hierarchy (LEACH) is a cluster-based protocol proven to increase energy efficiency in sensor networks. However, LEACH also has disadvantages such as a selection of cluster heads that don't consider residual energy at every node. It is the cause of failure in the election process and affects the stability of the network cluster. Period network stability is essential as reliable feedback from a network. Therefore, this study tries to investigate and solve stability problems in the LEACH algorithm. In this paper, the authors propose a new protocol that is Optimization-LEACH (O-LEACH), which is the development of the LEACH protocol. The O-LEACH protocol cluster-head selection process is developed based on the initial energy of each node, and a new beginning energy levels calculated from each node to every round. The test results show that the proposed O-LEACH protocol has a better stability period and network lifetime than the LEACH protocol.]]>
