Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control Design and implementation of remotely monitoring system for pH level in Baghdad drinking water networks Subject The topic of the resource Arduino uno Drinking water pollution GPRS sim900 Measurement of pH sensor Water quality monitoring Description An account of the resource Many people in the recent days have suffering from number of diseases due to unsafe and impure drinking water, especially in rural areas. As typical laboratory experiments and official water quality tests take considerable amount of time to obtain results and due to non availability of a simple device that can measure such water quality parameters in real time, therefore in this paper a remote pH level monitoring system for Baghdad drinking water system is proposed. A PH level sensing and monitoring nodes are distributed at different location. These nodes are proactively measured pH level of water and send data to the maintenance center to give them overall picture about pH level via global position system (GSM). This proposed system gives a robust, low-cost and effective method for the drinking water maintenance center to measure and monitoring the water quality in real time environment.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control MgCeAl11O19:Tb3+ and Mg8Ge2O11F2:Mn4+ in enhancing the color quality of remote phosphor LED Subject The topic of the resource Color quality scale Luminous flux Remote phosphor package Triple-layer structure WLEDs Description An account of the resource As the name infers, the triple-layer remote phosphor (TRP) has 3 phosphor layers includes the red Mg8Ge2O11F2:Mn4+ phosphor layer on the top, the green MgCeAl11O19:Tb3+ phosphor layer in the middle, and the yellow YAG:Ce3+ layer at the bottom and is mentioned as a solution to increase the chromaticity and luminescence adequacy of the white LEDs (WLEDs) in this article. As to control the red light for higher value achieve in the color rendering index (CRI), using red Mg8Ge2O11F2:Mn4+ phosphor in the TRP structure is recommended. All the outcomes indicate that when red phosphor Mg8Ge2O11F2:Mn4+ concentration grows the CRI gets higher values, and drastically declines when the concentration of green phosphor MgCeAl11O19:Tb3+ increases. As the same time, applying the green MgCeAl11O19:Tb3+ phosphor layer to manage the green light as it can make the luminous efficacy (LE) of WLEDs increase. In particular, the index of LE can also be improved over 40% by limiting the scatter of light and putting in green light. Moreover, to preserve the average correlated color temperature (ACCT) stable at 8500K, the yellow YAG:Ce3+ concentration must be cut down as the concentration of red and green phosphor rise.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control JPG, PNG and BMP image compression using discrete cosine transform Subject The topic of the resource Discrete cosine transform Image analysis Image compression Image processing Image transformation Description An account of the resource This paper proposes image compression using discrete cosine transform (DCT) for the format of joint photographic expert groups (JPEG) or JPG, portable network graphic (PNG) and bitmap (BMP). These three extensions are the most popular types used in current image processing storage. The purpose of image compression is to produce lower memory usage or to reduce memory file. This process removes redundant information of each pixel. The challenge for image compression process is to maintain the quality of images after the compression process. Hence, this article utilizes the DCT technique to sustain the image quality and at the same time reduces the image storage size. The effectiveness of the DCT technique has been reasonable over some real images and the implementation of the technique has been compared with different types of image extensions. Matlab software is an important platform for this project in order to write a program and perform the progress of project phase by phase to achieve the expected results. Based on the tested images, the DCT technique in image compression is capable to reduce the image storage memory in average about 50% of each image tested.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control Distribution power loss minimization via optimal sizing and placement of shunt capacitor and distributed generator with network reconfiguration Subject The topic of the resource Distribution generation Radial distribution system Reconfiguration power loss Shunt capacitor Description An account of the resource The population is speeding up and the demands for electrical energy are clearly increasing, this growth in load leads to higher power loss and Voltage drop. This paper is focused on a method to decrease the power losses and voltage profile improvement. The first suggested technique binary particle swarm optimization (BPSO) is utilized for solving the problem of the power loss minimization in network distribution. This work based on optimum position and sizing of the distribution generation (DG) units, shunt capacitor (SC) with network reconfiguration is applied to show the improvement of the network distribution efficiency. The MATLAB programming part and software package MATPOWER7 are used to simulate 69-bus and 33-bus test system with three different cases of loads and different number of DG and SC. The result showed a positive impact on system efficiency in comparison with other previous studies. This paper showed that increase of DG and capacitor does not usually give the best result although the increase of system cost, maintenance, and the units' distance for gas supplying.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control Time series analysis of electric energy consumption using autoregressive integrated moving average model and Holt Winters model Subject The topic of the resource Akaike information criterion Autoregressive integrated moving average Energy consumption Holt Winters Management of energy Time series forecasting Description An account of the resource With the increasing demand of energy, the energy production is not that much sufficient and that’s why it has become an important issue to make accurate prediction of energy consumption for efficient management of energy. Hence appropriate demand side forecasting has a great economical worth. Objective of our paper is to render representations of a suitable time series forecasting model using autoregressive integrated moving average (ARIMA) and Holt Winters model for the energy consumption of Ohio/Kentucky and also predict the accuracy considering different periods (daily, weekly, monthly). We apply these two models and observe that Holt Winters model outperforms ARIMA model in each (daily, weekly and monthly observations) of the cases. We also make a comparison among few other existing analyses of time series forecasting and find out that the mean absolute percentage error (MASE) of Holt Winters model is least considering the monthly data.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control Enhancement of luminous flux and color quality of white light-emitting diodes by using green (Y,Gd)BO3:Tb3+ phosphor Subject The topic of the resource (Y,Gd)BO3:Tb3+ Color quality scale Luminous flux Mie-scattering theory WLEDs Description An account of the resource In the study, we analyzed and clarified the effect of green (Y,Gd)BO3:Tb3+ phosphor on chromatic homogeneity and optical performance of multi-chip white light emitting diodes (MCW-LEDs). Thereby there is a solution to get the best luminous efficiency. In addition, (Y,Gd)BO3:Tb3+ is known as one of the factors that has a significant impact on lighting performance, so it needs to add the (Y,Gd)BO3:Tb3+ phosphor in the structure of LEDs to combine with the yellow phosphor YAG:Ce3+ to receive the best results. Therefore, the concentration and size of (Y,Gd)BO3:Tb3+ should be choose carefully so that the presentation of MCW-LEDs would be more incredible. The results show that when the concentration of green-emitting (Y,Gd)BO3:Tb3+ phosphor tends to increase, it also helps the color homogeneity and the lumen efficiency of MCW-LEDs with the average correlated color temperature (CCT) of 5600 K-8500 K become better.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control The impacts of red-emitting phosphor Mg8Ge2O11F2:Mn4+ on the color rendering index of convex-dual-layer remote phosphor WLEDs at 5600 K Subject The topic of the resource Luminous flux Mg8Ge2O11F2:Mn4+ Mie-scattering theory WLEDs Description An account of the resource The poor color rendering index (CRI) induced by mono chip and phosphor configuration in the conventional white-light light-emitting diode (LED) urges for developments in both packaging and material, thus, a modern lighting solution was introduced. The dual-layer phosphor package is an innovative configuration that can retain the lumen output of conventional white light emitting diode (WLED) while also enhancing color quality. The structure of dual-layer phosphor package that was proposed includes two chips and one phosphor. The priority in this research is to keep improving the lighting properties of WLED, therefore, further experiments with this dual- chips and dual-phosphor package are conducted. The lighting properties of LED are measured multiple times with its nitride-based phosphor being altered in proportions and densities each occasion, the results are calculated with a color design model made specifically to monitor and adjust the color of white-light from LED to match desired outcome. The WLED at 5600 K correlated color temperature (CCT) is the sole research object of the experiments. The measured parameters from the 5600 K WLED and the color coordinates of CIE 1931 simulated from the color design model show that 0.0063 is the highest possible discrepancy at 5600 K (CCT). The information from this manuscript provide the manufacturers with the most efficient approach to create a white LED that has good color quality, high CRI and luminous flux.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control Identification the internal parameters for mono-crystalline solar module using Matlab-simulation and experimental ascertainment Subject The topic of the resource Mono photo-voltaic (PV) cell P-V curve Matlab_Simulation Modelling five-parameter PV model Description An account of the resource The research studies the effects of some weather parameters for Baghdad city on the output of the solar module of the type monocrystalline. The experimental part measures the electrical parameters of the photo-voltaic (PV) module for three levels of radiation rate 500, 750, and 1000 W/m2 . The theoretical part includes the modeled and simulation of the PV panel, via the proposed mathematical single–diode model (SDM, 5 parameters), and Matlab- simulation. The Newton Raphson method was applied to find the output current of the solar panel and the plotting P-V, I-V curves. The work involves preparing a simple mathematical model to estimate the optimal ambient conditions to give the highest output of the solar module. The validation of the model was verified by the practical testing of the cell for 6 months. The best results were obtained at standard testing conditions (25°C, 1000 W/m2 ). The output power calculated by the mathematical model was 30.1 W while from experimental work was 30.45 W. The relative error is 1.15%. The converge between experimental and modeling results for the same conditions is about 98.9% that proves the validity of the proposed model and the possibility of using it for all types of photovoltaic.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control Using flat phosphor layer in dual-layer remote phosphor configuration to improve luminous efficacy Subject The topic of the resource Color rendering index Lambert-Beer law Luminous efficacy Remote-phosphor white LEDs Description An account of the resource The phosphor layer shape and components distances are the subjects proposed to advance the quality of WLEDs in this article. The two distances, between phosphor layers (d1) and between the phosphor layer and the LED chip (d2) in Flat dual-remote phosphor (FDRP) and Concave dual-remote phosphor (CDRP) were examined by experiments to determine their impacts on WLEDs lighting performances. The results suggest that FDRP is a better option than CDRP for lighting performance. In each respective structure, the distances influence the lighting capacity and color output whenever they fluctuate. Therefore, to effectively control and study this phenomenon, the correlated color temperature is maintained at 8500 K, and the concentration of phosphor material is altered while the distances are changing. When d1 and d2 are at the starting value of 0, the recorded lumen output and chromatic performance of lighting devices are the lowest and begin to increase as d1 and d2 expand. Bigger d1 and d2 mean bigger scattering area and better chromatic light integration, which leads to higher color quality. Detailed results present that optimal values of d1 or d2 for the highest lumen output of 1020 lm are 0.08 mm or 0.63 mm, respectively. Meanwhile the lowest color deviation is accomplished with d1=0.64 mm or d2=1.35 mm.
