Abstract

In 2014, Cikarang Listrindo Energy built a steam power plant in Babelan to participate in the government programs. In April 2017, Unit 1 of PLTU Babelan has been operated. After the plant has been in operation for 4 months, the plant will have a performance test for the main part of the steam power plant, one of which is the steam turbine performance test. This performance test purpose is to get actual performance data where it will be compared to the design data, and it willl be used for warranty from the steam turbine contractor. The performance test is using ASME PTC 6 for steam turbine performance test. The steam turbine performance test can be seen from several parameters such as test capability, heat rate and turbine efficiency. The results of the steam turbine performance test based on the design are: the output power is 138,010 MW; the heat rate is 8865 kJ/kWh; and the turbine efficiency is 87.38%. Meanwhile the results of the performance test based on commissioning are: the output power is 139,295 M; the heat rate is 8919 kJ/kWh; and the turbine efficiency is 87.03%. The actual performance test results are: the output power is 137,595 MW, the heat rate is 8830.64 kJ/kWh, and the turbine efficiency is 88.65%. The tolerance given from ASME PTC 6 is 2%. Exhaust turbine pressure affect the turbine efficiency, where as lower exhaust turbine pressure causes higher turbine efficiency.

Abstract

This research aims to Design and Development of Real-Time Monitoring & Controlling Infant Incubator with Tilt Stabilizer Using Raspberry Pi Remotely Controlled via PC and Smartphone to Reduce Tilt during Baby Transfer. An experimental approach was used, involving data collection, controller determination, hardware design, circuit schematics, software design, and user interface development. Raspberry Pi was selected as the controller due to its sufficient GPIO pins for reading sensors and operating actuators. The tilt stabilizer was created using NEMA 17 stepper motor and a self-designed flexible screw nut to ensure precise tilt adjustment. During testing, the system demonstrated reliable performance, verified through analysis of test data and sensor readings on the HDMI-connected screen, and remote accessibility via PC and smartphone using the internet. The incubator's temperature consistently maintained 37°C using PID control. On an inclined surface of 20°, the tilt stabilizer effectively maintained a stable 10° inclination during baby transfers.

Abstract

This research aims to create a prototype of an energy storage optimizer in a PV system using a supercapacitor in combination with batteries. The purpose of adding supercapacitors in this prototype is to maintain battery usage when there is a change in irradiation with a loading source that refers to the amount of electrical current and voltage as a supply of energy. A sudden increase in load without an energy buffer component can affect battery endurance. This can result in a decrease in electrical energy supply. Based on experimental results, it has been found that the battery and supercapacitor complement each other. The battery works more statically while the supercapacitor works more dynamically. Thus, the power output to the load is more stable, and the battery can be more durable because when there are extreme changes in irradiation and load, they can be overcome by supercapacitors.

Abstract

At the present time, technology is developing rapidly in various scientific fields. People continue to develop and research the latest technologies to make human life easier. One of them is in the field of IoT (Internet of Things) technology. The use of electrical devices in each power source has different electrical power consumption. And this often happens, so when using electrical equipment, each power source is a tool for monitoring the use of electrical power, so that the use of electrical power in multiple power sources is in accordance with the required power. Therefore, a tool is designed that can facilitate the performance of activities to monitor the use of electric power, the results of which can be displayed through LCD 16X2 and can be informed through the Internet. The purpose of this research is to design an IoT-based electric power monitoring system to facilitate the monitoring of electric power consumption in multiple IoT-based power sources. The method used in data collection is quantitative method. With the collection of several components needed, which are designed in this study such as voltage sensors, Ethernet shields, hub switches and Arduino Uno microcontrollers. This research will monitor IoT-based power, and can be monitored via the Internet in the form of a graphical display on a desktop application or in the form of a monitoring web page. The results showed that the average error value in testing the voltage sensor was 0.02%, the sensor for current readings had an error value of 0.19%, and the value of power was 0.18%. So it can be concluded that by having a fairly small difference and error, this tool is said to be quite good and then by testing the monitoring application system on the web page that is made capable of sending, storing and displaying data on the monitoring web page in real time every minute even with different power sources, in tests conducted with two different power sources and can be measured properly, so that testing the web monitoring application can be said to be good because it can monitor electrical power of multiple power sources.

Abstract

Maintenance of electrical installations continues to be carried out in maintaining reliability of continuity of electricity distribution. Distribution transformer maintenance activities are carried out in a state without voltage. Of course, with condition without voltage, it has an impact on power outages which can reduce reliability value of the distribution system. In 2024, PT PLN (Persero) UP3 Cempaka Putih has carried out transformer maintenance activities at 7 distribution substations with an average outage duration is 155 minutes. At Distributon Substation TP117, transformer maintenance has been carried out using a minimal outage method, namely by utilizing Mobile Transformer Units as mediator for temporary load transfer during maintenance. Total duration of the outage was only 44 minutes with value of SAIDI is 0.035 minutes/customer and value of ENS is 245,084.07 Wh. By calculating the SAIDI and ENS values based on the pure duration of maintenance work, SAIDI value is calculated to be greater, amount 0.102 minutes/customer and the ENS value is 708,515.77 Wh. So it can be determined that the potential reduction for SAIDI value is 65.69% and ENS value is 65.41%. This means that the reliability of the distribution system can increase because the SAIDI and ENS values can be reduced.

Abstract

Mountain water is the main raw material in drinking water depots and water from drinking water companies is known as healthy water and good for consumption, people think this water is the best, while the population, costs increase every year, and transportation terrain is increasingly difficult, how long can this condition last. River water and soil that are properly processed, namely filtration and ozone disinfection, can be a substitute for mountain water, by designing, creating, and implementing appropriate technology to process river water and soil so that it is suitable for consumption. Plasma Generator is a tool for producing Ozone, which is used as a strong disinfectant and without residue in water. This tool uses a spiral cylinder electrode method with Dielectric Barrier Discharge (DBD). Corona release occurs between high voltage electrodes of 13.28 kV from a distance between electrodes of 0.5 mm, capable of producing ozone that can purify dirty water and sterilize water containing E. coli bacteria.
