This research was focused on the use of metaheuristic optimization in neural network for time series modeling. The three optimization methods were used as experiments, i.e Genetic Algorithm, Particle Swarm Optimization, and Modified Bee Colony. Neural network architecture chosen in this research was Feed Forward Neural Network. The weaknesses and limitations of gradient-based methods inspired many researchers to try to use other methods. Non-gradient based method is a reasonable choice consideri...
The most prominent protocols for data transfer in Internet of Things (IoT) are Message Queuing Telemetry Transport (MQTT) and Constrained Application Protocol (CoAP). The existing clients from both sides are unable to communicate directly because of the packet’s header structure difference in application and transport layer. In response, this paper aims to develop a bidirectional conversion server used to translate the specified messaging protocol interchangeably in the OpenFlow network and tran...
Quantum dots (QDs) is considered as a potential material for the improvement of light-emitting diodes (LEDs). However, different from the traditional phosphor materials, they have unique scattering and absorption properties affected by their several nanometers sizes, which makes their application in the production of LED confronts more challenges. In addition to this, the influence of QDs on QDs-converted LEDs (QCLEDs) is barely studied. In order to propose solutions for those problems, in this ...
Anapedia is a web-based encyclopedia designed specifically for children. The web was built because there are still very few Indonesian-language encyclopedias for children. This study aimed to evaluate the usability of the Anapedia website developed for children in Indonesia to retrieve information available in a wide range of areas. In the context of usability evaluation of children encyclopedia, this is the first study to analyze usability problems identified by experts during the heuristic ins...
COVID-19 has spread throughout the world. The detection of this disease is usually carried out using the PCR-RT swab test. However, limited resources became an obstacle to carrying out the massive test. To solve this problem, CT-scan images are used as one of the solutions to detect the sufferer. This technique has been used by researchers but mostly using classifiers that required high resources, such as CNN. In this study, we proposed a way to classify the CT-Scan images by using the more effi...
E-business security becomes an important issue in the development of technology, to ensure the safety and comfort of transactions in the exchange of information is privacy. This study aims to improve security in e-business systems using a hybrid algorithm that combines two types of keys, namely symmetric and asymmetric keys. Encryption and decryption of messages or information carried by a symmetric key using the simple symmetric key algorithm and asymmetric keys using the RSA algorithm. The pro...

The article presents the results of modeling the solution to the problem of determining the reliability of the components of a multiservice communication network (MCN) based on the theory of fuzzy sets. The main characteristics of the equipment that affect the reliability parameters of the MCN are given. To solve the problem of determining the reliability of MCN components based on the theory of fuzzy sets, a multiservice network is presented in the form of a hierarchical diagram, which shows th...
Multi-chip white LED lamps (MCW-LEDs) with outstanding featurers are regarded as an advanced lighitng solution. However, to further the application of MCW-LEDs in the lighting industry better achivements must be found, thus, this paper focus on improving the color uniformity and luminous flux with green phosphor Ca 2 La 2 BO 6.5 :Pb 2+ . The results, which were measured through experiments conducted in WLEDs with average correlated color temperature from 6600 K – 7700 K, show enhancements in col...
Abstract: Recently, algorithms of machine learning are widely used with the field of ‎ electroencephalography (EEG)-Brain-Computer interfaces (BCI). The ‎ preprocessing stage for the EEG signals is performed by applying the Principle ‎ Component Analysis (PCA) algorithm to extract the important features and ‎ reducing the data redundancy. A model for classifying EEG, time series, signals for facial ‎ expression and some motor execution processes had been designed. A neural ‎ network of three hid...
Market segmentation in higher education institutions is still rarely applied although it can assist in defining the right strategies and actions for the targeted market. The problem that often arises in market segmentation is how to exploit the preferences of customers. To overcome this, a combination of geographic, demographic, psychographic, and behavioral criteria from students was used. Then, cluster analysis using the hybrid method between K-Means and SOM algorithms was applied based on mul...
