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

The Bali electrical network sub system is supported by the Java-Bali power transfer assisted by the Bali power generation. Most of these power plants are not economical, so the Java-Bali power transfer is prioritized. If an island operation occurs, the Bali sub system loses most of the power that supports its load. This loss of power can result in a black out. The Bali sub system must perform overload shedding equal to the loss of Java-Bali power transfer. However, because the magnitude of the Java-Bali power transfer is very dynamic, the amount of Over Load Shedding (OLS) is difficult to predict, so an optimization system is required that can calculate the amount of OLS according to the Java-Bali power transfer at any time. The optimization system can also determine OLS targets before Faults occur based on the Priority Scale. To ensure that the Optimization System has worked properly, an Adaptive Defense Scheme (ADS) simulation was created. In this simulation, the optimization system will be tested using the ADS simulation series. In this simulation, the optimization system will be tested using the ADS simulation series. This system is simulated so that it can work OLS target off contact. This system will be tested for the suitability of the load selection with the amount of Java-Bali power transfer. The load selection is compared with manual calculations using the same method to ensure the optimization system calculations are appropriate. Comparison between the selection of targets for the optimization system with calculations, and working contacts is made by making a suitability matrix. From the tests carried out, it was obtained that OLS System Optimization System target size was calculated with a maximum deviation of 5.5%, a minimum deviation of 0.037%, and an average deviation of 1.03%. The system is also capable of selecting targets with 100% accuracy and can also perform MTDS digital output according to 100% accuracy, that the operational system efficiency can be achieved very significantly.

Abstract

This study analyzes the suitability of the earthing system of household electrical installations in the Natura Cluster, Bekasi, with the PUIL 2011 standard, considering that the increase in power and degradation of old installations increase the risk. A qualitative approach with data triangulation (measurement, observation, documentation study) was used. The results of earthing resistance measurements with a Digital Earth Tester showed values above the PUIL 2000 standard (<5 Ω) at a depth of 50 cm (average 13.17 Ω) due to the soil structure. However, at a depth of 300 cm, an average value of 0.03 Ω was obtained, meeting the standard. This indicates that the cluster kWh installation meets the feasibility standard at the optimum depth. This study recommends a review of the earthing system, including planting depth, understanding soil characteristics, periodic maintenance. Also, system reassessment, and grounding cable insulator coating. This is intended to improve the safety and reliability of the residential electrical system.

Abstract

This research aims to analyze the electric current of elevators equipped with both three-phase induction motors and permanent magnet motors under varying load conditions (0%, 50%, and 90% of elevator capacity). Data was collected through direct observation using a Kyoritsu KEW 2007 current clamp. The results indicate that there is no significant difference in electric current and power consumption between 0% and 90% load conditions for both motor types. However, a notable difference was observed at the 50% load condition. The study suggests that permanent magnet motors are preferable due to their easier maintenance.

Abstract

Water is a natural resource that is very important for life, but often its utilization is less than optimal due to the limitations of an effective monitoring system. This research aims to design and build an Internet of Things (IoT)-based water level monitoring and control system using NodeMCU ESP8266 and Blynk application. The system is designed to operate in manual and automatic modes to improve water usage efficiency and reduce wastage. The research methods include literature study, experimentation, observation, testing, and analysis. The test results show that the system successfully fulfills its functions. The Blynk app can connect with the NodeMCU ESP8266 via Wi-Fi connection, and water level data can be obtained in real-time as long as the device is connected to the internet. In addition, the system can activate the pump manually through the control button, as well as operate automatically by turning on the pump when the water level is below the minimum limit and turning it off when it reaches the maximum limit. With the successful testing, the system is expected to be an effective solution for monitoring and controlling water levels in real-time, thus supporting more efficient and sustainable water management.

Abstract

Currently very rapid technological advances make it possible for various efforts to provide convenience and comfort for humans. One effort to provide convenience and comfort is through the development of home automation systems (Home Automation). One automation system that can be implemented at home is a system that can open the gate automatically without having to get out of the vehicle. Through the development of this system, it is hoped that house residents can open the gate from a certain distance without having to interact directly with the gate. Based on technological developments, especially in the field of electronics, telecommunications and applications, there is a microcontroller system, namely Arduino Uno, which can be used by humans to communicate with Android smartphones via the NodeMcu Esp8266, so that it can be used for gate opening applications without using conventional methods, but is quite accessible. via an Android smartphone only, the overall circuit of the gate system with Android control is divided into 3 parts, including: power supply, input section and output section. The power supply section is the voltage input obtained through the adapter. The input section consists of 1 input, namely Android, Arduino uno R3 and NodeMcu Esp8266. The output section consists of a servo motor and buzzer and LED light.

Abstract

Energi listrik sangat penting dalam kehidupan modern dan kebutuhannya terus meningkat seiring pertumbuhan populasi. Hal ini menuntut pengembangan sistem distribusi listrik yang andal. Salah satu masalah umum dalam sistem distribusi adalah rendahnya faktor daya (cos φ < 0,85 lagging), sering disebabkan oleh beban kapasitif berlebih, yang berdampak pada susut tegangan dan penurunan kualitas daya. Gedung X di Jakarta, yang memiliki kapasitas listrik besar dan menggunakan panel LVMDB serta kapasitor bank 700 kVar, mengalami anomali pembacaan pada digital power meter saat kondisi off operasional. Penelitian ini bertujuan mengevaluasi sistem kontrol instalasi listrik dan mengidentifikasi penyebab pembacaan beban tidak normal. Metode yang digunakan adalah deskriptif kuantitatif melalui observasi, pengukuran langsung dengan alat ukur seperti tang ampere dan thermal imaging camera, serta studi literatur. Hasil penelitian menunjukkan bahwa kapasitor bank yang tetap terhubung tanpa beban nyata menyebabkan cos φ menurun dan pembacaan beban meningkat secara tidak wajar. Hal ini disebabkan oleh kontaktor yang tidak terputus sepenuhnya. Setelah kapasitor dilepas, arus listrik turun dan faktor daya meningkat, sesuai standar Permen ESDM No. 20 Tahun 2020.
