<![CDATA[This study proposed a tool that can set the direction of the solar cells that will always follow a shift of the light source and always facing perpendicular to the sun using solar system auto scanning. Commercial DSSC was proposed using a synthetic dye that is kind of a ruthenium complex dye has reached 10% efficiency, but the availability and the price is expensive does not allow for the development of this research so that the research will be used ZnO with Dye N3 a more easily available and cheaper. To optimize the performance of the solar cell, material will be added CNT nano-materials on silicon. Prototype of dye-sensitized solar cell (DSSC) was made using materials ZnO and CNTs that can increase the power by 5.18%. Auto scanning was able to move in 3 dimensions to follow the direction of motion of the sun through the increase reached 7.5%. Electric control system was set up by detecting the maximum light intensity and adjusting the position of the direction of the solar cell, solar lighting by using microcontroller ATMEGA 32, light sensor and motor driver. This technology had been able to improve 14.73%.]]>

<![CDATA[Kukuh Karyadi, Jatmiko Endro Suseno in this paper explain that Water is a necessity of life that is very important for mankind. The availability of clean water has been sought to be fulfilled in various ways. One of them is by making a clean water treatment plant that can process water that is not yet suitable for consumption to be more feasible and ready to be consumed for everyday life. The operation of water treatment plant is still manually operated such as in the Iron Removal Filter (IRF) control system so that the processing is not easy to operate. To facilitate the operation of a clean water treatment unit, a control system based on a Programmable Logic Controller (PLC) is created on the Iron Removal Filter (IRF) processing unit. Control system consisting of PLC, relay circuit, power supply and Human Machine Interface (HMI), works to control the clean water processing unit including controlling the process on the IRF automatically. Also made a prototype of a water treatment plant consisting of an aerator unit, an IRF unit, a storage tank, several pumps and several control valves to be controlled by the control system in operation. The control system uses PLC as a control center because PLC is a controller that is simple, easy to program and very reliable as already widely used in the industrial world. The PLC brand used is Omron because it is cheap, reliable and has software named CX-Programmer which is easy in programming. The control system uses laptop computer as an HMI in the operation. HMI uses VTScada software and is connected to a PLC using OPC CX-Server software. The control system that is made can control the clean water processing unit in the form of a prototype. Operation on HMI is so easy and has a very attractive appearance. So it is highly recommended to be used in the actual clean water treatment unit]]>

<![CDATA[The control of the ordinary water treatment unit on refinery location is still operated manually(by operator), especially in the filtering unit (IRF unit). There are 9 manual block valves that must be operated every 8 hours, to keep the water quality meets its specification. Manual operation can increase the risk of errors or delays in the operation or movement of service cycles and regeneration sequences. Subsequently, it can decrease the water quality and unefficiency in production. The automation of the water treatment unit was made using the nextion HMI touch screen circuit, Arduino Uno microcontroller, IC shift register, electronic relay and other electronic components. By connection between the Nextion HMI as an interface and the Arduino Uno microcontroller as electronic relay controller, the design of the control unit was able to control the clean water treatment unit simulator in accordance with the principles of the processing unit.Keywords: Water treatment unit, nextion, arduino uno]]>

<![CDATA[The Non Planar MOSFET structure with curved-channel is one alternative MOSFETÂ structure for enhance the electrical performance. The study was focused on the non planar deviceswhich has curved-channel including grooved-gate, recessed-channel, V-shaped and sidewallvertical MOSFET. The presence of corner region can effective in reducing the electric field at thedrain, thus improving reliability of short channel effects (SCEs). The corner effect can reducesurface potential. It can improve the characteristic of the device electrical performance, especiallythe reduction of short channel effect and hot carrier effects. Therefore, the curved-channelMOSFET has a very great application prospect in deep submicron device architecture.Keywords: MOSFET, Non Planar, curve channel, surface potential, short channel effects]]>

<![CDATA[An instrument of pulse generator of ultrasonic wave and its implementation for distance measurement between two objects have been created through analysis using oscilloscope. This ultrasonic wave may be used in a distance measurement, material reflection analysis, and product’s depth. An ultrasonic oscillator is made with set of IC 555 as the setter of pulse amount and multi vibrator mono stabile set of IC 555 as the oscillator of ultrasonic frequency, pulse amplifier through transistor BD 139. An ultrasonic transducer using transducer 400ST/R160 and micro controller AT89S51 is used for time setter. In the amplifier set of ultrasonic receiver, Op-amp CA 3204 is used. AT89S51 is used for time setter that is made repeatedly in order that the bounce may be read on oscilloscope through P1.0. After conducting an experiment, the effective working area frequency in pulse generator of ultrasonic wave is obtained in the frequency of 38.23 kHz. In the experiment on the amount of effective pulse, the maximum reach effectively is 16 pulses. In the experiment on the distance between two objects, the writer finds out that an instrument linier grade is 0.81773 against standard measurement with R=0.99954 and SD=0.457. Meanwhile on the material reflectivity test, the writer may concludes that the bigger material mass, the bigger its reflectivity. Keywords: pulse generator of ultrasonic wave, transducer]]>
