Abstract

An overhaul was conducted for maintenance on Gas Turbine unit 2, type SGT 800 at PLTGU Tanjung Uncang, with the purpose of preventive maintenance. The operating hours of the gas turbine exceeded the maintenance schedule, reaching around 36,000 working hours, whereas maintenance should have occurred between 20,000 to 30,000 working hours. The discrepancy between the actual working hours and the standard maintenance schedule for the gas turbine was due to the Tanjung Uncang power plant operating on a base load system, requiring the turbine to run continuously for 24 hours. This study aims to analyze the thermal efficiency, heat rate, and specific fuel consumption before and after the overhaul. The method used in this study is the thermodynamic analysis calculation of the Brayton cycle. By performing thermodynamic analysis to determine the gas turbine's efficiency and calculating specific fuel consumption, heat rate, and thermal efficiency under load, the comparison of the gas turbine's efficiency values can be determined. The thermal efficiency after the overhaul increased by 5.17%. The heat rate after the overhaul decreased by 1867.806 kJ/kWh. The specific fuel consumption after the overhaul decreased by 0.037 kg/kWh. The overhaul impacted the maximum load that could be produced by gas turbine unit 2. Before the overhaul, the maximum load was 36 MW. After the overhaul, the maximum load increased to 45 MW. This increase in load is influenced by temperature, fuel flow rate, and pressure.

Abstract

Gas and steam power generation units often experience changes in load according to the requested electricity needs. Changes in generator workload will also affect the efficiency of the generator. The different efficiency in each workload will have an effect on the amount of heat rate production produced when compared. By calculating the efficiency at each load, it will be useful to find out the workload with the best performance. From the results of the enthalpy calculation process based on the temperature of each gas turbine process, in this study the gas turbine performance is calculated, and then it compares the turbine performance with variations in operating load. The turbine performance that will be calculated includes compressor power, turbine power, net power, thermal efficiency, compressor efficiency, combustion chamber efficiency, turbine efficiency, heat input, and heat rate. The results of the calculation of the highest average thermal efficiency at 27 MW load were 35.18%; the average compressor efficiency experienced the highest increase at 25 MW load of 83.24%, followed by an average increase in combustion chamber efficiency and an average decrease in turbine efficiency at each increase in load, as well as experiencing the lowest decrease in heat rate at 27 MW load conditions of 2,842 kJ/kWh

Abstract

Penyerbukan silang antarbudaya memiliki yang sama dengan penyerbukan silang pada tumbuhan (alogami) yang hanya melibatkan serbuk sari yang mengalami penyerbukan. Proses ini mengilustrasikan bahwa kebudayaan asing tidak dapat kita ambil seluruhnya, tetapi hanyalah sisi positif yang dapat dipadukan dengan kebudayaan Indonesia agar lahir kebudayaan baru guna membangun kebudayaan Indonesia yang unggul. Perpaduan antara budaya Indonesia dengan budaya asing juga tidak hanya terjadi pada satu aspek, namun mencakup keseluruhan aspek yang berlangsung dalam realita kehidupan masyarakat. Setiap aspek tersebut dapat dipadukan dengan budaya lokal bangsa Indonesia, sehingga menghasilkan kebudayaan baru yang lebih baik dan dapat membangun identitas nasional Indonesia. Hal ini dikarenakan akan terbentuk budaya baru yang lebih unggul dan lebik baik hasil dari penyerbukan silang antar budaya. Penyerbukan silang ini akan memperkuat kebudayaan bangsa sebagai identitas nasional bangsa Indonesia. Hal ini dikarenakan identitas nasional merupakan aset berharga sekaligus ciri khas dari bangsa Indonesia dan menjadikan bangsa ini memiki ciri khas yang dijadikan sebagai kekayaan bangsa Indonesia.

Abstract

Transformers are critical components in electricity transmission, and system failures can be catastrophic. PT Energi Listrik Batam has a 150 kV power transformer that experienced an oil leak in the Low Voltage section in September 2023. Transformer oil serves as an insulating material. Insulation Resistance and Breakdown Voltage tests showed a decline in oil quality, with an insulator value of 50 kV. PT Energi Listrik Batam conducted oil purification to restore its quality. Purification removes gases and particles that degrade oil quality. As a result, after purification, the insulation resistance and breakdown voltage of the transformer oil increased to 80 kV.

Abstract

The internet of things is defined as a technology that enables control, communication, collaboration with various hardware devices, various data, virtualizes all real things in the form of the internet and others through the internet network. In this study, a monitoring system for the height of granulated powder was created using a lidar sensor based on the internet of things which uses a measurement method via a lidar sensor. Data from the lidar sensor will be processed on the microcontroller and ethernet shield which is responsible for sending sensor data using an internet connection. Furthermore, it will be displayed on the website online. The results obtained from this simulation are tools designed to facilitate human work, reduce lost time, so that operators do not need to monitor granulation powder directly into the tank. Based on the test results and data analysis, the height of the granulated powder is directly proportional between the reference points using a measuring device with a lidar sensor or the design tool itself with a not too great difference of 4 cm or 0.022%
