Single phase induction motor usually has two windings. Because of that, the motor usually operated at lower efficiency than the poly-phase induction motor. A new design had been developed by using poly-phase winding to improve motor efficiency, but characteristic of the current winding at low load condition is not good. So that, this study was aimed to design a 4 phase windings construction of a single phase induction motor that using capacitance control of the run capacitor on auxiliary winding. This design was focused for capacitor-start capacitor-run induction motor that had 4 windings, one winding act as the main winding and the other three windings act as the auxiliary windings. The main and the auxiliary windings current rating of the proposed motor were 2.74A and 3.15A, respectively. The auxiliary winding current of the proposed motor was controlled by the â€˜Arduino Unoâ€™ control system. To get the best control system of the proposed motor, the performances of the proposed motor were compared to the performances of a conventional single-phase induction motor that had the same current rating, stator and rotor construction. The single-phase comparator motor used in this study was a conventional single-phase induction motor of 220V, 50 Hz, 1 HP, 8.3A, 4 poles, 1400 RPM cage rotor. The result showed that the proposed motor with capacitance control in auxiliary winding had better performances than the conventional induction motor.

Everyone must have a rush outside the house, sometimes in a hurry even forget to turn off and turn on the light in the house during the morning or night. At times like this, of course, that makes people lazy to go back to the house to turn off the light that causes electricity waste and make time efficient to turn on the light. In this study a prototype of lighting control will be made where observations have been made about the prototype need. Then look for literature related to light control prototypes. The prototype method uses the blynk application as a light controller connected to the internet with the media via wifi. ESP-01 as a microcontroller processes commands from a smart phone which then results in controlling both the off and on the lights as well as the receiver and transmitter in the lighting control system. Thyristor switch module as an electrical switch instead of a manual switch at home to turn on or turn off the light through commands from the microcontroller. This prototype is very easy to use because through a prototype smart phone can be controlled, so this is a solution for humans to turn on or turn off the light by utilizing wifi in the house. From the experiments that have been carried out the average speed of the prototype tool receives an order from open source blynk application in 0.28 seconds

This research discusses the Arduino Uno based public street lighting intensity control system. The street lighting technology applied so far is still conventional technology that is classified as wasteful of energy because it still uses a continuous lighting system or an On-Off system. PJU problems arise because of too much power consumption caused by the use of large power lamps and lamp operating times. This research utilizes Arduino Uno and RTC to control the value of the variable voltage output transformer based on time division. This system has been able to control the voltage of 400 watt sodium lamps. Â The output voltage of the transformer has been divided into three levels, namely level 1, level 2 and level 3. The division of this level is based on the operating time of the lights, namely level 1 at 1830 WIB to 2200 WIB, level 2 at 2201 WIB until 2359 WIB, level 3 at 0000 WIB until 0530 WIB. Transformer output voltage at level 1 can be 220 volts. The output voltage of the transformer at level 2 can be 210 volts. Transformer output voltage at level 3 can be 200 volts. The intensity of the 400 watt sodium lamp light at level 1 is an average of 99.9 lux. The intensity of the 400 watt sodium lamp light at level 2 is an average of 85.45 lux. The intensity of the 400 watt sodium lamp light at level 3 is an average of 78.6 lux.

Water is an important compound for all forms of life on earth. The depth of water is closely related to productivity, vertical temperature, light penetration, density, oxygen, and nutrients. The depth of water affects biota which are cultivated. It is related to the pressure received in the water, because the pressure increases as the depth increases. This research makes Remotely Operated Vechile (ROV) to measure water depth using MS5803-14BA pressure sensor, joystick controller and eqipped with Arduino Mega as the control of the ROV. The ROV is also equipped with a camera to monitor the underwater condition. In this research, the ROV is designed to ease people in measuring the depth of water without diving. The ROV is designed to produce good measurements at depths above 1 meter, with error values of 0.3% to 2.1%. Therefore, ROV can be applied as a measurement media of the water depth. Moreover, the camera on the ROV is able to monitor underwater condition which gives good image results in clear water condition. Therefore, it is useful to search objects in the ocean.

The use of multiprocessor methods in robotics systems has a significant impact on overall robot performance. The Master-slave method is a model of a multiprocessor system where there are several processors that communicate with each other to carry out the robot's overall function. RS-485 can be used as a communication model in the master-slave method. RS-485 is a development of RS-232 which has the ability to communicate with several nodes. In this research, an experiment will be conducted to implement RS-485 to support the master-slave processor communication. Stages of research began with making system design, which includes the design of embedded hardware systems, the design of data communication protocols on RS-485 networks, software design, followed by implementation and testing. The test is carried out to measure the time response of the device to three data transmission models, namely broadcast, addressing slaves without responding and addressing slaves with responses. The test results carried out on three slaves with a communication speed of 9600 bps. Measured response time on broadcast data transmission is 8ms, and address slave without response is 7ms. Whereas delivery by addressing slaves with responses, shows that the measurement method cannot be applied.

The development of digital technology makes it easy for humans to do activities, including compliance with the requirement of voice, data, and video communication in office buildings. Infrastructures are a primary consideration for a reliable connection, large-capacity, and stable communication lines. Recently, Fiber-optic communication systems are now the backbone of information signal delivery technology. This paper proposes a design of optical fiber transmission media for deployment in urban office buildings. It has been called fiber to the building (FTTB), which uses a fiber optic communication system to support the availability of multimedia network in an office area. A typical office building in an urban area has a multilevel structure that is used by various companies with multimedia network access services to support business activities. This study considers XGPON technology as a fiber optic-based broadband access technology that is deemed appropriate to the needs of the use of a multimedia network. The design begins with conducting a data collection survey. The next is the chosen device components based on the estimated distribution of the number of users. There are three parameters will be calculated include Power Link Budget (PLB), Rise Time Budget (RTB), and Bit Error Rate (BER), to determine the design feasibility. Based on PLB, RTB, and BER data, the proposed fiber to the building (FTTB) can meet the parameters to be achieved in the design, namely PLB of -27,24 dBm for downstream and -11,68 dBm for upstream, the value of is 0,049 ns, and value of BER is 0,186 x 10-1085. The design of FTTB can meet the requirement of users with a bandwidth of 9014,4 Mbps for 1200 users.
