Abstract

Various types of ceramic materials are mostly found in Indonesia which have different common properties, so lab experiments are needed to determine the natures of the breakdown voltages, capacities, and factors which determine the performance of each ceramic insulator. Type of ceramic tile studied were of diferent platinum, ceramic tile brands. The experiments sho that, the average breakdown voltage of ceramic platinum is 8.12kV, the room conditions during testing were 29.70C, 989mB air pressure and humidity 77%, while the average breakdown voltage of ceramic milan was 9.12kV, where condition during the test was 29.10C, 990 mB air pressure, relative humidity 79% and for brands essenza average breakdown voltage 39.68kV, under a testing temperature of 29.90C, pressure 989 mB air and 66% humidity. Of the three types the ceramic platinum brand was most easily penetrated by the voltage. This is do caused by the existing cavities in the ceramics and does not meet the standard ceramic or solid materials and most of them have the ability to withstand the breakdown voltage ceramic materials essenza brands.

Abstract

Conventional faucet by twisting operation can be replaced with automation systems for the purpose of easy operation and to save water. Solutions to these can be solved utilizing electronic technology. With the use of sensors on the electronic switch circuit faucet and filling water in the reservoir will work automatically according to the expected circumstances. Thus the tap to remove the water and do not need to stop playing, because tap water out if a member body directed to the front of the sensor and stop the flow water if it is not directed at members of the body. While in the reservoir, water will always be awake capacity so there is no excess water runs out or when charging. In detecting the presence or absence hand directed towards utilizing sensor ultrasonic and as overall system control using AVR microcontroller atmega16. While on the test results show that there are differences in the amount of water volume released on automatic washing appliance less the regular tool so that there is efficient use of water. Based on the testing tool can be run well and as a tool in this thesis is a simulation then to apply it in real conditions necessary adjustments to take into account such things as the distance between the electrodes used in the reservois, the distance between sensor ultrasonic and distances between each faucet. This system will work automatically turn on the faucet using ultrasonic sensors as an object detector.

Abstract

This research is do to make Very Low Pressure Phase-II Project which be expected to not like the last project which have not appropriate between plan and implementation. It is because the increase of activity which is not planned before and student’s syndrome behavior. Student’s syndrome like spin out time is occur because the safety time in every activity and when a project have a problem, with the result that the estimation time and cost is bigger. Therefore, it be made a plan with applied Critical Chain Project Management method. From primer data and secondary data be treated with microsoft project software. This method is to hide safety time in every activity and change with buffer time. Increase buffer time with using cut and paste method is add project buffer half of critical chain duration at the end of chain and put feeding buffer with half activity to activity at not critical chain which bring it to critical chain. The result of research is when a project is already start and no changes, so the project can finish during 370 day with cost 3,558,232.73 USD. When the project is not appropriate, then buffer time can be consumed about 185 day with resource buffer cost about 334,767.27 USD and total of finished project is 555 day, a safety time for Very Low Pressure Phase-II project.
