Abstract

Energy saving must be carried out by the government, companies or the community. The high consumption of electricity is a strong reason to optimise electrical energy and lighting systems in buildings and other public places. In this study, the author uses a genetic algorithm to optimise the use of electrical energy and lighting in the Kualanamu Airport building. Genetic algorithm is a computing technique based on the principle of evolution in genetics. This study aims to test the effectiveness of using genetic algorithms to optimise the lighting system of the Kualanamu Airport building. The data used in this study is real-time data from the MCB power system or the airport building meter. Based on the calculations and analysis carried out in this study, it can be concluded that the AG evaluation presentation test has the best results with an average crossover of 0.3-1, an average mutation of 0.05-0.5 and an average generation of 92, with a fitness value of 1,438.72.

Abstract

PT PLN (Persero) is a state electricity company that plays a crucial role in the distribution of electricity for the needs of the community, including supporting transportation activities, electronic devices at home/office/school/hospital, and, of course, electricity for a better life. In the current era, the challenges and demands for service and the reliability of electricity supply from customers are very high. In such conditions, the speed of handling during power disturbances becomes a benchmark, so both preventive and corrective work needs to be improved to maintain the reliability of the electricity supply, considering the values of SAIDI-SAIFI, Recovery Time, and ENS in electrical disturbances. In the distribution of electrical energy to consumers, there is a protective device called FCO (Fuse Cut Out). According to SPLN 64:1985 and SPLN D3.026:2017, FCO is a protective device that operates when there is an excess current disturbance. This device will disconnect one electrical circuit from another when the current passing through exceeds its working capacity. The working principle of FCO is to melt the fuse link inside the FCO tube, causing the FCO to detach. FCO is installed in the 20 kV distribution network, serving as protection for distribution transformers and network protection at branching points.

Abstract

The distribution system of electrical power networks serves as a means to distribute electrical energy to both industrial and household consumers. With the increasing population growth, the number of electrical energy users or consumers also increases, potentially impacting the loading on each distribution transformer. If the loading on each transformer increases, it can lead to overload, load imbalance, power losses, and damage to the transformer. Therefore, to ensure the proper operation of distribution transformers, PLN (a state-owned electricity company in Indonesia) has set a standard for the loading on distribution transformers, which should not exceed 80%. This research aims to measure the loading on distribution transformers and analyze the occurrence of power losses caused by load imbalance. Measurements are conducted using a clamp meter and earth tester to obtain current and voltage values as well as the resistance value of grounding. Subsequently, calculations are performed for transformer loading, load imbalance, and power losses on the feeder.

Abstract

Peningkatan kebutuhan energi listrik seiring dengan pertumbuhan populasi dan perkembangan teknologi menuntut peningkatan suplai dari pembangkit listrik, terutama yang menggunakan bahan bakar batu bara. Persaingan bisnis di sektor pembangkit listrik mengharuskan perusahaan mengelola sumber daya dengan optimal untuk mencapai laba maksimal. Bahan baku sebagai bahan bakar memainkan peran penting dalam operasi pembangkitan tenaga listrik, dan gangguan pada persediaan dapat menghambat proses produksi serta mengurangi laba. Suplai daya dari pembangkit sangat dipengaruhi oleh permintaan beban, kemampuan unit pembangkit, dan rugi-rugi pada saluran. Biaya bahan bakar yang tinggi dapat membuat operasi pembangkitan menjadi tidak ekonomis. Oleh karena itu, diperlukan strategi untuk meminimalkan biaya operasi sambil memenuhi variasi beban, melalui penjadwalan operasi generator dan koordinasi antar pembangkitan. Metode First in First Out (FIFO) dalam pembagian pembebanan dapat membantu mencapai efisiensi biaya dengan menentukan kombinasi daya keluaran dari setiap unit pembangkit secara ekonomis. Dengan demikian, optimalisasi pembebanan bertujuan untuk mencapai biaya operasi yang optimal dan ekonomis, memperhatikan batasan kapasitas unit pembangkit.

Abstract

This research focuses on modeling and simulating temperature and pressure parameter settings in geothermal power plants using MATLAB software. Geothermal power plants utilize geothermal heat as an energy source to produce electricity, so controlling temperature and pressure parameters is a key factor in optimizing system performance. The method used in this research includes developing a mathematical model of a geothermal power generation system, followed by numerical simulations to evaluate the dynamic response to variations in operational parameters. Simulation results show that proper regulation of temperature and pressure can increase plant efficiency and operational stability. In addition, this study also explores the influence of various parameter setting scenarios on the power output and energy consumption of the system. Implementation of the model in MATLAB makes it easy to visualize and analyze data, and allows real-time simulations needed for fast and accurate decision making. In conclusion, this research succeeded in showing that modeling and simulation using MATLAB is an effective tool for optimizing temperature and pressure parameter settings in geothermal power plants, which in turn can increase overall system efficiency and reliability.

Abstract

The design of Proportional-Integral-Derivative (PID) control systems is a critical aspect of control engineering to achieve system stability and optimal performance. How-ever, tuning PID parameters often poses challenges due to the complex analytical ap-proaches required. This study analyzes the application of GeoGebra, a dynamic mathe-matics software, in designing PID control systems visually. GeoGebra is utilized to model control systems, visualize system responses, and perform interactive PID parameter tun-ing. The study involves simulations of simple linear systems, such as actuator position control, to evaluate the effectiveness of the GeoGebra method compared to traditional approaches. The analysis focuses on performance parameters, including rise time, peak time, and steady-state error. The results demonstrate that GeoGebra simplifies the PID parameter tuning process through intuitive visualization, enhancing concept comprehen-sion and design efficiency. Furthermore, GeoGebra proves to be an effective tool for edu-cation and training in control engineering.

Abstract

Permintaan energi listrik yang semakin meningkat seiring dengan pertumbuhan populasi dan industrialisasi telah menjadikan pengelolaan sumber daya energi sebagai tantangan utama di berbagai negara. Efisiensi penggunaan daya serta perencanaan yang matang sangat penting untuk memastikan ketersediaan energi yang stabil dan berkelanjutan. Dalam konteks ini, sistem forecasting atau peramalan penggunaan daya harian memainkan peran krusial. Seasonal Autoregressive Integrated Moving Average with Exogenous Regressors (SARIMAX) adalah salah satu metode yang telah terbukti efektif dalam menangani data time series yang kompleks. Metode ini merupakan pengembangan dari model ARIMA (Autoregressive Integrated Moving Average), yang telah digunakan secara luas dalam peramalan data time series. Model ARIMA sendiri merupakan model yang sangat populer dalam analisis time series. Model ini terdiri dari tiga komponen utama: Autoregressive (AR), Integrated (I), dan Moving Average (MA). Penelitian ini bertujuan untuk mengembangkan dan mengimplementasikan sistem forecasting penggunaan daya harian menggunakan metode SARIMAX. Diharapkan penelitian ini dapat memberikan kontribusi signifikan dalam pengelolaan energi yang lebih efisien dan efektif, serta menyediakan dasar yang kuat bagi pengembangan sistem forecasting yang lebih canggih di masa mendatang.
