Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control The better distant phosphor configurations for enhancing WLED color intensity: YVO4:Eu3+ and YF3:Mn2+ Subject The topic of the resource Correlated color temperature Mie-scattering theory Phosphor structure YF3:Mn2+ YVO4:Eu3+ Description An account of the resource The distant phosphor configuration produces more illuminating beams than the two settings containing conformal or in-cup phosphor. When this configuration is used, though, it is difficult to manage the color standard of light-emitting diodes (LEDs). As a result, in past few years, numerous studies have focused on controlling the color standard of distant phosphor configurations. Until present, two distant phosphor configurations of single- and triple-film phosphor configurations, have been used to improve color standards. This research will investigate the ideal configuration among these configurations in terms of color rendering index (CRI), color quality scale (CQS), lumen output (LO), as well as color homogeneity for multi-chip white LEDs (WLEDs). WLEDs, operating at five different temperatures of color between 5600 K and 8500 K, are used to perform the studies. The results reveal that the three-sheet phosphor setting would be more desirable, with greater CRI, CQS, and lumen efficiency (LE) indexes. Furthermore, when using a triple-layer phosphor arrangement, color variation is reduced, resulting in a rise in color consistency. This conclusion is possibly verified by using Mie theory to analyze scattering properties in distant phosphor setup, making the study findings legitimate and important data to produce more advanced WLEDs.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control The improvement of the color rendering index using convex-dual-layer remote phosphor geometry with YOCl:Eu3+ Subject The topic of the resource Color rendering index Dual-layer remote phosphor geometry WLEDs Mie-scattering theory YOCl:Eu3+ Description An account of the resource White-light emitting diodes (WLEDs) are semiconductor light sources whose construction design is usually made up of a single pumping chip and a single light-conversion film of phosphor compound. The outstanding problem of this traditional setting is the inadequate chroma rendering index (CRI). Introducing a cluster of multiple blue chips with more than one phosphor layer is demonstrated to address that flaw of W-LEDs. This package is called the dual-film remote-phosphor multi-chip WLED. As a consequence, both the light brightness and the CRI are improved. However, for the maximum results, the test on the second layer of phosphor has been performed to continually alter the proportions and densities of phosphor within the silicone. The researchers employed a unique hue design to control the white-light light emitting diode (LED) module. When comparing the actual result to the simulated color coordinates under the hue standard of international commission on illumination (CIE) 1931, the highest difference is found to be around 0.0063 for correlated color temperatures (CCT) of 6600 K and 7700 K. Experiments indicate that the setting of multi-chip and dual-phosphorus is the optimal design for supporting CRI quality and luminous intensity.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control Research on advancing chromatic reproduction and luminosity of a WLED using triple-layer remote phosphor arrangement Subject The topic of the resource CaLaB3O7:Ce3+,Mn2+ Color quality MgB2O4:Mn2+ Triple-layer structure WLEDs Description An account of the resource In this study, the use of triple-sheet phosphor arrangement (TRP) in performing significant improvements to both color quality and luminous flux of white light emitting diode (WLEDs) is introduced. The phosphor layer of CaLaB3O7:Ce3+,Mn2+ is to accomplish green-spectra enhancement for the boost of luminous efficacy (LE), while MgB2O4:Mn2+ red phosphor layer is for red-spectra enhancement to better color rendering index (CRI) of WLEDs. The changes in these two phosphors’ concentrations present considerable effects on the yellow phosphor YAG:Ce3+ concentration, the color quality scale (CQS), CRI, and LE. Findings display the decrease of YAG:Ce3+ concentration accompanying the increase of red and green phosphor concentrations, for the stabilized average correlated color temperatures (ACCTs) between 6000 and 8500 K. Results also reveal that greater content of MgB2O4:Mn2+ leads to greater CRI value. Meanwhile using the increasing CaLaB3O7:Ce3+,Mn2+ concentration, the CRI lowers considerably. CQS, on the other hand, can increase with CaLaB3O7:Ce3+,Mn2+ concentration from 10% to 14%. Especially, given the enhancement for the CRI as well as CQS, LE value will surge to more than 40% due to the reduction of scattering light and the addition of green light. The outcome of the study is a priceless reference for light emitting diode (LED) producers.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control Safety precautions in the usage of extension cords by students in halls and hostels Subject The topic of the resource Electric shock Extension cord Fire outbreak Safety Description An account of the resource This paper presents the evaluation of the safety measures adopted by Ho Technical University (HTU) students in the use of power extension cords in their halls and hostels, along with their safety considerations for properly selecting these cords to avert fire outbreaks or prevent them from becoming a potential fire hazard. Whenever extension cords are utilized inappropriately it can lead to fire or electric shock perils. The assessment of the awareness level of safety practices is yet to be rigorously pursued as an agenda towards extension cord usage in institutions and agencies perceived to be high energy consumers where fire outbreaks occur frequently. A quantitative research approach was adopted, using a questionnaire for data collection. The findings revealed that about 52% of the respondents did not know the current and power ratings and the effects of overloading the extension cord. It was recommended that consumers purchase extension cords that have been endorsed by an autonomous testing laboratory, whereas the university should immediately organize a seminar to educate the staff and students about the use of the extension cord.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control Ring slot CP antenna for the hybrid electromagnetic solar energy harvesting and IoT application Subject The topic of the resource CP antenna Energy harvesting Hybrid electromagnetic solar IoT application Description An account of the resource The research proposed a compact antenna integrated with dual-function solar cells to optimize internet of things (IoT) communication devices and energy harvesting. The use of integrated solar cells with electromagnetic elements as antennas and energy-gathering in a design is a solution for wireless communication sensors and simultaneously electromagnetic and solar energy harvesting. Radiation performance testing of solar cell antennas and optical experiments were carried out to test the ability of solar energy collection. A double feed ring slot circular polarization (CP) antenna coplanar antenna with a configuration has highly sensitive to vertical and horizontal waves. It is to accommodate the impact of circular polarization wave and solar cell distortion on antenna performance. This technology promises green communications, renewable energy, and environmental protection to combine wireless communication and green battery components. The study presents the performance and design results of a double line-feed microstrip antenna circuit connected with CP antenna on the S-band for IoT communication by accommodating electromagnetic energy transmission. The importance of adopting an integrated radio frequency (RF) solar energy harvesting strategy rather than a single source method makes this research very significant in its novelty by optimizing the analysis of multiple signal access in IoT communications.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control A survey on security and policy aspects of blockchain technology Subject The topic of the resource Bitcoin Cryptocurrency Digital mining Encryption Initial coin offerings Description An account of the resource This survey talks about the problem of security and privacy in the blockchain ecosystem which is currently a hot issue in the blockchain community. The survey intended to study this problem by considering different types of attacks in the blockchain network with respect to algorithms presented. After a preliminary literature review it seems that some focus has been given to study the first use case while, to the best of my knowledge, the second use case requires more attention when blockchain is applied to study it. The research is also interested in exploring the link between these two use cases to study the overall data ownership preserving accountable system which will be a novel contribution of this work. However, due to the subsequent government mandated secrecy around the implementation of data encryption standard (DES), and the distrust of the academic community because of this, a movement was spawned that put a premium on individual privacy and decentralized control. This movement brought together the top minds in encryption and spawned the technology we know of as blockchain today. This survey explores the genesis of encryption, its early adoption, and the government meddling which eventually spawned a movement which gave birth to the ideas behind blockchain.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control Hybrid convolutional neural networks-support vector machine classifier with dropout for Javanese character recognition Subject The topic of the resource Convolutional neural networks Dropout Javanese character recognition Multilayer perceptron Support vector machine Description An account of the resource This research paper explores the hybrid models for Javanese character recognition using 15600 characters gathered from digital and handwritten sources. The hybrid model combines the merit of deep learning using convolutional neural networks (CNN) to involve feature extraction and a machine learning classifier using support vector machine (SVM). The dropout layer also manages overfitting problems and enhances training accuracy. For evaluation purposes, we also compared CNN models with three different architectures with multilayer perceptron (MLP) models with one and two hidden layer(s). In this research, we evaluated three variants of CNN architectures and the hybrid CNN-SVM models on both the accuracy of classification and training time. The experimental outcomes showed that the classification performances of all CNN models outperform the classification performances of both MLP models. The highest testing accuracy for basic CNN is 94.2% when using model 3 CNN. The increment of hidden layers to the MLP model just slightly enhances the accuracy. Furthermore, the hybrid model gained the highest accuracy result of 98.35% for classifying the testing data when combining model 3 CNN with the SVM classifier. We get that the hybrid CNN-SVM model can enhance the accuracy results in the Javanese characters recognition.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control Driving cycle development methods: case study in Malaysia Subject The topic of the resource Driving cycle Emissions Fuel consumption Hybrid Electric Vehicle Micro-trip Description An account of the resource Over the years, many models have been created to estimate pollution inventories and fuel usage. These models can be divided into two types: travel-based and fuel-based. One of the most used travel-based models for estimating emission inventories is driving cycles. It can be used for a variety of different things, such as establishing pollution regulations, traffic control, and calculating journey time. For these goals, researchers have previously attempted to use easily available, well-established driving cycles. In many ways, however, the local environment differs greatly from that of the driving cycle’s genesis. As a result, these cycles’ applications have failed to provide high-quality results. This research aims to analyse the various approaches utilised for driving cycle construction in various locations of Malaysia under varied operational situations.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control A bandwidth reconfigurable antenna for devices in low UWB-applications Subject The topic of the resource Band notched E-shaped slot PIN diode Switchable frequency Ultra-wideband Description An account of the resource A reconfigurable simple design planar antenna for ultra-wideband applications is proposed, with E-shaped slot contained four narrow vertical slots that has the capacity of switching using four PIN diodes with a ground plan and a microstrip power line. An additional circularly polarized (CP) band is obtained by changing the on/off states of the PIN diodes. Moreover, the four PIN diodes are attached in the middle of the E-shape slot and used to switch the radiation flow of the patch. For validation, a patch antenna design is offered, based on a distinctive situation analysis. The antenna offers the low-ultra-wideband (UWB) frequencies band. Therefore, the switch of the operating states of PIN diodes gives us a good bandwidth re-configurability. In addition, with this flexible configuration we achieve a good -10 dB bandwidths with the ability to change the bandwith ranges from narrow-band 2.3 GHz to wide-band 3.1 GHz. Also, we achieve a large band for 3 dB AR is 2.57 GHz.
