Abstract The oxygenate water level is an important adjustment parameter in the operation of the fire generator set, and the water level may result in the safety of the water pump. The high water level will not only affect the oxygen effect, but it is also possible to cause the water shot to the steam turbine to cause a water shot or give the water tank full water, oxygenate vibration, drain and vapor with water. When the load is low (generally 35% rated load), the oxygenate water level is controlled by large and small valve, condensate pump variable frequency control condensed water drum pressure. When the unit load is high (greater than 35 rated load), the oxygenate water level is controlled by the condensed water pump, the large valve and small valve controls condensed water drum pressure.

<em>Plenty of water and electricity are wasted in residential areas because people often forget turning off the water pump or do not know when the water tank is full. Solution of these problems is using a water level control as an automatic tool to turn off  and turn on the water pump. However, the water level control that exist today has many shortcomings. It has a complicated operating system, especially for people in a residential area with a range of price more than IDR 50,000. So this study was conducted with the aim of simplifying the system of water level control so its price is more affordable and simple operation, knowing the working principle and study the effectiveness and efficiency. From the research that has been done resulting an automatic water level control with more simple system and a production cost of IDR 19,000 with a selling price of IDR 25.000.</em>

Feed water tank merupakan salah satu komponen pada boiler yang memiliki fungsi penting dalam menyuplai air ke boiler. Level air pada feed water tank harus tetap dijaga agar tidak terjadi kekosongan saat proses pengisian air ke boiler. Selama ini operator masih memantau secara langsung level air pada feed water tank. Sehingga diperlukan sistem otomasi water level control yang dapat membantu operator dalam mengontrol dan memantau level air pada feed water tank. Sistem otomasi water level control dikendalikan oleh PLC Omron Sysmac C200H dengan menggunakan panel push button yang terpasang pada plant atau juga dapat dikendalikan dan dimonitor melalui melalui PC menggunakan software SCADA Wonderware InTouch 10.5. Selain itu sistem otomasi menggunakan SCADA ini dilengkapi password sebagai pengaman dari orang yang tidak bertanggung jawab. Kata kunci : PLC, SCADA, water level control, feed water tank Feed water tank is one component of the boiler system which has an important function in supplying water to the boiler. Water levels in feed water tank is must be maintaned to avoid emptiness at filling process to the boiler. Previously, the operator directly to monitors water level in the feed water tank. Therefore, a control mechanisem is required to help the operators to control and monitor the water level in the feed water tank autonomously. In this system, water level is controlled by PLC Omron C200H Sysmac using the push button panel attached to the plant or also can be controlled and monitored by PC using Wonderware InTouch 10.5. In addition, SCADA system is equipped with a password to secure from irresponsible people.Key word : PLC, SCADA, water level control, feed water tank

Transient Response Analysis

Control Principle course is a part of syllabus in the diploma or degree in Electrical Engineering programme where students are exposed to topics such as time response analysis. One of the topics in this course is Transient Response analysis where it requires students to calculate the characteristic of the response based on set of formula. One of the difficulty encounters in delivering this topic is students having difficulty to relate the theory with the application as most theoretical part of this topic does not explain on how the transient response graph is obtained in the first place. In order to address this problem, this paper proposed E-Water Level educational kit that can be used by student in order to understand independently the transient response analysis by applying theory on the water level control application where the student knowledge on Transient Response parameters are tested, namely the delay time, rise time, damping ratio and setting time. The system consists of Arduino Microcontroller, water tank, water pump, relay, ultrasonic sensor and electronic display. The novelty of this educational kit is that the educational kit is adaptive in bridging the gap between theory and application in which the data is generated by real application of water level and the answers for the questions are automatically generated based on the data obtained. Thus, each student will experience different set of question.

Smart Flush is an innovative product in mechanical engineering. All the skilled workers need to      improve the quality of product that would be manufacture. The three objectives of this study are as  follows: (i) to design automatic water level control based on electrical conductivity of the water; (ii) to improve the supply of water into the water tank as well as avoiding any accessing water; and (iii) to provide easy installation and maintenance. 5W + 1H concept are used to solve the problem. The     existing water level for toilet flushing system employs mechanical method, which is commonly expose to mechanical failure. This research introduces the notion of water level controlling within the context of electrical conductivity of the water. System design integrates the electrical and electronic based   water level sensing and couple with solenoids shut off valve in a wired environment. The system equipment is lower power consumption, equipment only work when the water level changes, usually is in a waiting state. Smart Flush approach would help in reducing water overflow and low water pressure in the piping system. Maintaining water level inside the toilet pump system is an essential aspect in order to avoid waste of water due to overflow.

The monitoring and water level controlling system is one sample of the simple industrial automation. Monitoring  and controlling SCADA based water level can make it easier to do observation and controlling real time. This research have to design system water level control using ultrasonic sensors and equipped with display interface on laptop. This research is an R&D research that starts from the phase of  problem identification,  desing, and  testing. Test results show good performance in accordance with the desired, where the water pump can be turned on when the water level at the reservoir reaches 10 cm and will be stopped automatically if the water level in tank reaches 70 cm. Monitoring and controlling water level can be done in real time on the laptop interface. So this system can be used as an alternative SCADA learning Media.

Most of the individuals in residential areas experience the problem of running out of water and overflow tanks. It becomes more difficult for the consumer to gauge the amount of water in the tank. When the pump is ON, the user will not realize that the water tank is filled, which may result in an overflow. Auto water pump switch is used to troubleshoot problems with the water tank. The consumer can use this technology to fill an empty tank without having to take any effort. When the tank is empty, the system automatically turns ON, and when the tank is filled, it automatically turns OFF. Water is not wasted with this technique
