Abstract
In Indonesia, many LED drivers have a large Reactive Power and Small Power Factor thus not suitable with harmonic standards. It causes expensive electricity by using LED Driver on a large scale like in factory and office. LED Driver is one of the most important components in Lightning Equipment which has the greatest harmonic value for use in factory or office. A good LED driver must have power factor value more than 0.86 of small reactive power and suitable with harmonic standards. This proposed study uses Linear LED Driver using Low Pass Filter and Single Tuned Filter, which using measurement and comparison based on harmonic standard with power factor value less than 0,86. Since it has a low price, fit harmonic standard, low reactive power and high power factor. The result shows that the measurement using Single Tuned Filter PF 0,97; THDi 24,3%; Q 2.5 VAR; P 11 W and Low Pass Filter PF 0.9; THDi 23% ; Q 1.3 VAR and P 2.709 respectively.

Abstract
This paper describes the research results to identify the characteristics of objects using image processing with the method of flat area geometric measurement, color measurements, size measurement, shape characteristics, and texture characteristics as data information used to decide on two groups of objects using the method of the Linear Discriminant Analysis for the application of mangosteen grading and sorting process. The proposed solution method is the use of four image sensors placed at four different monitoring angles. Each image sensor provides a decision on the group of objects it identifies, "accepted" if it meets all the objects requirements or "rejected" if one of the objects characteristics requirements is not met. The results of each image sensors decision are sent to the sink node in the wireless sensor network environment to be decided together using the sensor fusion method whether the objects identified in the group are "accepted" by all image sensors or "rejected" by one or more sensors image. The grouping results give a 10% error rate, and the biggest identification error comes from the color measurement.

Abstract
In the modern era, the use of the latest technological tools is increasingly widespread. One of them is UAV (Unmanned Aerial Vehicle) or unmanned aircraft. Quadcopter is one of the UAV which is often used for various needs such as land mapping, taking pictures of the Bird View building. But not many people use it as disaster warning monitoring. In this research will be conducted on land movements that have a disastrous impact such as landslides or breakdown embankments. Such disasters do occur suddenly, but if they can be identified periodically and reported quickly, they can be avoided. It is hoped that this research can overcome the problem of early identification of land movements that have a disastrous impact. The output produced in this study is a picture of periodic soil movements in the form of a GUI (Graphical Unit Interface).

Abstract
This paper aims to implement the Fuzzy Inference System algorithm as a controller in an IoT-based observation system in a brooding system simulator. The system consists of sensor and actuator nodes that are connected to the internet using microcontroller. The two nodes are connected wirelessly. Sensor nodes as devices that collect input data variables that is temperature and humidity. The value of the sensor readings is sent to Antares cloud storage by microcontroller which functions as a data storage so that it can be accessed by the user as well as input controller. The Mamdani Fuzzy Inference System algorithm is implemented on the actuator node. The actuator node takes fuzzy input values from Antares and then outputs in the form of a PWM crisp value that aims to regulate fan speed and heating level. The experiments performed were comparing the calculation of the algorithm using MATLAB and the brooding system simulator. The results showed identical outputs with practical results with an average error of 0.11% for the PWM value of the fan and 0.22% for the PWM value of the heater. The scheme is expected to be an alternative solution for implementing the control algorithm on an IoT-based system.

Abstract
A monitoring technology for large area with low-cost and high efficiency is highly demanded. Wireless Sensor Network (WSN) is the solution for a monitoring technology. However, not all monitoring must be continuous, there are some monitoring that can be carried out periodically. Therefore it is possible to invent a mobile sensor communication system on multicell networks. This research aims to implement a WSN system by collecting data from mobile sensors on multicell networks. The focus of research is on the design of mobile sensor communication with low-cost device as transceivers, namely NodeMCU. The design is implemented using 4 NodeMCU units, 3 of them are functioned as access points, while 1 unit is employed as a client connected to the sensor. The experimentation was conducted by varying transmission distances of sensors with and without barriers. Moreover, handover and blankspot areas are also included accordingly. The result of experimentation shows that the usage of low-cost devices has still possibility to built monitoring mechanism on multicell networks eventhough the transmission power was significantly influenced by the availability of barriers.

Abstract
Solar panel is a device to convert light energy from the sun into electrical energy, most of solar panel is made from semiconductor such as silicon. Solar panel is still has many disadvantages such as expensive prices, low efficiency, the power output that depended on light intensity and temperature, etc. During the day, solar panel temperature could increase and affect the power output. It is found that temperature would reduce solar panel voltage output that also reduce the power output. In this research, 100WP Monocrystalline solar panel power output will be enhanced by using cooling system to reduce the temperature of the solar panel. Cooling system of the solar panel is applied by flowing the water on the surface of the solar panel using 12V DC water pump. The experiment starts from 11:00 AM to 01:00 PM. The result of this experiment is the power output of the solar panel increased up to 5.79 Watt with the average about 2.96 Watt and the temperature of the solar panel decreased by 20.99ºC. The temperature of the solar panel without cooling is about 52.83ºC and with the cooling system is about 31.85ºC.

Abstract
Indonesia, being a tropical country, has a high photovoltaic (PV) energy generation potential that can help meet demand due to impending shortage power supplies in the coming years. The shading effect is a negative effect that causes the Photovoltaic power output to drop from its normal state. The performance of Photovoltaic Panels (PV) is a shared module surface exposed to sunlight. Shading effects a result of the influence of clouds, but the influence of these clouds causes a lack of uniform illumination of sunlight received by the photovoltaic. This is condition called Partial Shaded. Partially shaded PV systems cannot operate at maximum efficiency because of shadows cast by surrounding structures, foliage and cloud cover. This paper describes an experiment on PV output for the irregularity of sun irradiation. Characteristics of I-V can be influenced by partial shading effect. The voltage and current of PV solar cells will drop from partial shading effect experiment which consists of 20%, 40%, 60%, 80% and 100% shading area

Abstract
Recently more attention on the failure of PV systems has been paid and more reports have been found in PV related papers. Various methods to detect failure of PV module have been developed; They are visual method, I-V characteristic method, electroluminescence (EL) method, UV fluorescence method, signal transmission method, IR thermography method, photoluminescence (PL) method. However, each method has some limitations. Developing a new alternative diagnostic method of PV cells will be required for efficient operation of PV system. We have been developing a new method for detecting failures in PV cells and modules by measuring magnetic flux density at the surface of PV cells generated by currents in busbars and a cell. The proposed method uses μ-tesla magnetic sensor (MI-CB-1DM) to detect failure in a PV cell. The experimental design carried out in this study covered two stages. In the first stage, we developed a method for detecting faults in PV cells using the μ-tesla magnetic sensor method. In this second stage a calculation will be made to determine the current level due to the failure of the PV cell. The results show that Bx at the lower busbar in the degraded module has smaller magnetic density than the upper busbar. No obvious difference can be seen in the Bx and By profiles between the normal and degraded cells.

Abstract
To improve services for train passengers, a tool that can display information to train passengers is needed. This information can be displayed on PIDS. PIDS serves to provide information in the form of the location of the train based on GPS coordinates then other information displayed in the form of the trains name, train number, wagon number, and the station the train will pass to. To display this information, PIDS uses components such as GPS, LED Matrix Display, Micro SD Card, which are then controlled by an algorithm using a microcontroller. The goal is to provide information to train passengers so can reduce errors that occur when the train passengers ride the train. In examination, PIDS can display all the information needed by passengers, although there are still some shortcomings such as amount of data that can be accessed from the Micro SD Card is only limited to 30 coordinate data. With the limited data that can be stored, it is very possible the occurrence of limitations in the number of coordinates of the station to be passed by the train in accordance with the route of the train

Abstract
Transmission lines plays important roles in delivering electric energy from generation site closer to the customer. Failure of a transmission line can cause significant economic loss due undelivered energy and may lead to catastrophic system black out. One critical part of transmission line is dead end connector, thus ensuring good condition of transmission line dead end connector is critical to avoid extensive losses. This paper investigates the cause of failure of dead end connectors that were installed in 150 kV ACSR lines. The failed connectors were examined and tested to find out the cause of the breakdown. Several samples of suspected bad connectors are also tested for comparison. Simulations using finite element software were conducted to provide broader insight on failure propagation. The investigation found that the dead end connectors were failed due to high current flowing through the steel part of the conductor which is caused by high contact resistance between the aluminum part of the conductor and the connector. Further study is needed to mitigate similar condition to occur in the dead end connector installation

Abstract
Emotion is one of the advantages given by God to human beings compared to other living creatures. Emotions have an important role in human life. Many studies have been conducted to recognize human emotions using physiological measurements, one of which is Electroencephalograph (EEG). However, the previous researches have not discussed the types of wavelet families that have the best performance and canals that are optimal in the introduction of human emotions. In this paper, the power features of several types of wavelet families namely daubechies, symlets, and coiflets with the Correlation Feature Selection (CFS) method to select the best features of alpha, beta, gamma and tetha frequencies. According to the results, coiflet is a method of the wavelet family that has the best accuracy value in emotional recognition. The use of the CFS feature selection can improve the accuracy of the results from 81% to 93%, and the five most dominant channels in the power features of alpha and gamma band are T8, T7, C5, CP5, and TP7. Hence, it can be concluded that the temporal of the left brain is more dominant in the recognition of human emotions.

Abstract
The Micro Hydro Power Plant is one of the plants with alternative energy sources that can be developed. Micro Hydro has the potential to produce energy from water movement due to sufficient difference in elevation and discharge. Irrigation channels have the potential for water resources that can be utilized for hydropower. Irrigation channel discharge in general is relatively fixed so that it becomes an excess because the discharge fluctuation is not too high. When added together, the potential of micro-hydro in irrigation channels is able to generate significant electricity. This paper will discuss Micro Micro planning with a low head suitable for irrigation channels and flat river flow. The results obtained will be used as a reference for developing small-scale power plants in the future.

Abstract
Low-cost sensor is now widely used in various application ranging from the environment to daily live application. On the other hand, the low-cost sensor signal is dealing with noises due to external disturbances, quality of sensor material, or its electronic circuit. The raw data provided by the low-cost sensor is also still in digital n-bit data, the conversion to the physical meaning is thus needed. In this paper, the low-cost sensor node as part of Wireless Sensor Network (WSN) for CO measurement based on electrochemical sensor module has been investigated. Although the measurement signal consists of noise, it could be attenuated by applying a digital IIR filter. By applying the Response Surface Method (RSM), the 10-bit data of sensor has been calibrated to the commercially CO detector and resulted in the th-square transfer function equation. The sensor node measurement performance has a strong correlation (R2=0.98) with the performance of the sensor module in the wireless sensor node system. The data has been transmitted well to a gateway with needed settling time about 5 minutes for getting stable measurement condition. The results can be used while dealing with a low-cost sensor in various application.

Abstract
Incident Energy is the energy released when an arc flash (electric arc) takes place in an electric panel. Arc-flash is a short circuit phenomena through the air that can possibly involve very high current or energy that can destroy anything around the spot. The incident energy is determined by the arc-flash current, the voltage, the distance between conductors (where the arc exists) and the duration of the arc-flash. However, this energy can endanger the safety of people working around the point of faults in the panel, especially technicians working for maintenance. Such events are still happened frequently in industries and many people become victims. Therefore, it must be anticipated and prevented to safe people working around and the panel itself. The aim of this paper is to examine arc-flash in a medium voltage utility panel at a power plant for safety reasons. In this paper the incident energy will be reviewed and analyzed based on standards and practical experiences and based on the results, the safety boundaries of the panel are calculated and the personal protective equipment (PPE) needed for the worker is determined. Therefore, by the application of these, the safety of people working around or close to the panel can be guaranteed. This study can also be used as a guidance for electrical engineer to examine or review the safe conditions of their electrical panels.

Abstract
It has to be realized that the era of conventional-oil is coming to an end. It will consume a lot of effort and cost to look for a new conventional-oil resource. However, unconventional-oil resources are abundant; most of oil reserves in the world are dominated by unconventional one (heavy, extra-heavy and bituminous oil). Heavy oil has density less than 16 0API and its viscosity greater than 400 cP at 100 0F (Visser, 1987). A critical problem that has to be faced during the production of heavy oil is its viscous characteristic which making heavy oil is not easy to flow naturally to the wellbore. Other issue is its composition dominantly composed by heavier hydrocarbon components. Therefore, thermal lifting methods are common ways been applied to squeeze residual heavy oil deposits. Steam flood and insitu combustion have been applied and studied vastly in over decades. However, steam flood and insitu combustion have some limitation on its field application. Therefore, heavy oil lifting needs an alternative method that able to produce heavy oil effectively and has high success ratio. A new technology that has been introduced as an effective way to produce it is microwave heating. This method utilizes micro radiation to vibrate the fluids and rock molecules in the reservoir to increase the temperature, then, reduce the oil viscosity. The microwave heating able to reduce oil viscosity from 4412.11 cP on its pour point at 51 oC to 134.24 cP at 90 oC. From the microwave heating, it is also known that the heating rate is directly proportional to output power and nano ferro concentration. The increase of temperatures also affected the recovery factor at 51 oC, 60 oC, 70 oC, 80 oC, and 90 oC, respectively the recovery factor are 0%, 28.55%, 34.07%, 35.32%, and 36.08%.

Abstract
The Solar cell performances as a power plant does not only convert energy, so that electricity is generated, but in the study of power systems it becomes a major element that has an important role in the study of power systems. As a power system element, the Solar cell acts as an element of electricity generation in this study modeled as a PV system and connected to the network, so it must meet the requirements of the electric power network operation. Through MATLAB / SIMULINK modeling and simulation, a 100 kW peak Solar Cell power plant has been modeled connected to the network. From the simulation and analysis obtained, this Solar Cell model shows that the connected load affects the voltage condition but does not affect the frequency. The load power factor also affects the network, namely with a lower load power factor, it affects the voltage on the grid.

Abstract
The development of red chili cultivation has not been so good in the conventional way, namely farming, technology of modern cultivation systems is needed, namely microcontrollers - sensors, aeroponic systems and greenhouses, as well as observing environmental conditions including oxygen. To observe the condition of oxygen, it was necessary to experiment with integrated equipment of aeroponic and green house microcotrolers which were carried out for 3 trials in the morning, afternoon and evening. In the morning the data collection was carried out at 9:00 a.m. to 10:00 p.m. Figure 5 is the result of oxygen monitoring in the morning. The set point needed for oxygen is 15 to 20 ppm (Part Per Milion). On oxygen control less than 15 ppm, pure oxygen will be given, but if the oxygen level exceeds 20 ppm the fan will be wrong to reduce the oxygen gas content around the roots of the red chili plant.

Abstract
Concepts connect the minimum number of passwords needed with the security system are monochromatic connectivity and rainbow connectivity. Rainbow connectivity has been introduced by Chartrand, et al. (2008), and monochromatic connectivity has been introduced by Caro and Yuster (2011). The focus of this paper is G, which is a simple, trivial, undirected, and 4-connected graph. Let s, and n be natural numbers, G is an ordered set of vertices set V(G) and edges set E(G), a 4-connected graph with order n. A coloring function d:E(G)→[1, s] is called rainbow edge s-coloring, if each pair of vertices u and v in V (G) has 4 internally disjoint u-v paths that have different colors or rainbow paths. The minimum number of colors needed so that each pair of vertices u and v in V(G) has 4 rainbow u-v paths called rainbow 4-connection number, rc4(G). Furthermore, the monochromatic u-v path is a u-v path that has the same colors. The monochromatic connection number, cr(G), is the minimum colors needed so that each pair of vertices u and v in V(G) has a monochromatic u-v path. In this paper, we show rc4(G) and cr(G) on some special graphs.

Abstract
Advanced Metering Infrastructure (AMI) is the foundation of the Smart Grid system. One of the most important parts of AMI is smart meter communication. Power Line Communication (PLC) technology utilizes the existing power line network for communication media between smart meters and Data Collector Units (DCU). One of the biggest challenges of communication using PLC is the noise level due to residential loads. In this study, laboratory test set up to measure noise caused by PV rooftop and residential loads are described. The measured signal is analyzed to find out the PLC frequency band with a low noise level. Experiments in the field are conducted to determine the performance of the PLC. Laboratory test measurement result shows the FCC band (150-490 kHz) is outside the range of PV rooftop and residential load noise. On the other hand, the Cenelec A (35-90kHz) frequency range is in the range of noise signal. Therefore, NB-PLC G3 using FCC frequency band is proposed to achieve robust data communication and lower noise level. G3 PLC FCC band are tested in the real field residential area, the experimental results show 97.62% successful rate within one week data collection.
