Abstract

Back flashover is one of the consequences of a direct lightning strike. Back flashover is caused by the higher grounding resistance value of the tower leg. Doing so can create an overvoltage and can cause damage to electrical equipment. One way to minimize overvoltage due to back flashover is to adjust the grounding resistance at the foot of the tower. Tower 10 has a grounding resistance value of the tower foot of 4.78 ohms, the total back flashover is 29.085544 times / year. Tower 50 has a grounding resistance value of the tower foot of 14 ohms and the number of back flashover disturbances is 85.0213544 times / year. In tower 10 the value of the grounding resistance of the tower feet is smaller than the value of the grounding resistance of the menra feet 50, so the total number of back flashovers on tower 50 is higher than tower 10. The greater the value of the grounding resistance of the tower feet, the higher the number of back flashovers. The average grounding resistance of the tower leg 1 - 249 Payakumbuh Koto Panjang has a value of 4.2847 ohm tower foot grounding resistance, the number of back flashover disturbances is 24.593635 times / year. The standard grounding resistance of the tower leg is 10 ohms, because tower 50 has a grounding pressure value exceeding the standard, which is 14 ohms, so that it can cause the number of back flashover disturbances to exceed the standard 13 times / 100 km / year.

Abstract

The increasing demand for sustainable energy solutions has driven the adoption of solar photovoltaic (PV) systems in various industries, including aquaculture. This study designs and simulates a solar power system for small-scale catfish (Lele) pond operations using the System Advisor Model (SAM). The methodology includes assessing energy requirements, selecting system components, conducting simulations, and performing an economic feasibility analysis. The results indicate that the designed 12-panel, 3-battery solar system effectively meets the pond’s daily energy demand while ensuring continuous operation during low sunlight conditions. The SAM simulation confirms stable electricity generation throughout the year, with seasonal variations minimally affecting efficiency. The economic analysis reveals that PLTS costs Rp. 150,365 per month, compared to Rp. 151,620 for PLN electricity, showing small but valuable long-term savings. Despite the high initial investment, solar power offers price stability, energy independence, and reduced reliance on fossil fuels. This study demonstrates that solar energy is a viable, cost-effective, and sustainable alternative for aquaculture operations. Future research should focus on optimizing system efficiency and integrating hybrid energy solutions to further enhance performance and financial benefits.

Abstract

Palmprint classification is a robust biometric method for personal identification due to its uniqueness and stability. This study explores the use of deep learning combined with the Laplacian Kernel and Deep Morphological Processing Network (DMPN) for palmprint classification. We trained the proposed system on a dataset of palmprint images collected from 10 participants, each contributing 10 palm images. The results demonstrated that the model achieved an accuracy of 90%, with weighted precision, recall, and F1-score all at 0.9007, indicating a well-balanced classification performance. Additionally, the model achieved a weighted precision of 0.9045, emphasizing its ability to minimize false positives. The average Equal Error Rate (EER) of 0.0917 indicates an effective balance between the false acceptance rate (FAR) and false rejection rate (FRR). The system was tested under various conditions, including different orientations, lighting, and backgrounds, demonstrating its robustness in real-world scenarios. This study also compares the results with recent palmprint classification techniques, such as deep learning, GANs, and few-shot learning, and discusses potential improvements, including incorporating multi-spectral data fusion and few-shot learning to enhance performance in real-world applications.

Abstract

The automation process in today's industrial world has become a necessity to realize the industrial era 4.0. The automation process in production also improves many aspects ranging from time, quality, and quantity of production results. Therefore, automation personnel or technicians who are experts in designing, manufacturing, repairing, and maintaining the hardware and software used are needed. These skills must be prepared with training tools that support current industry standards. This research aims to improve and test the feasibility of devices. The methodology used in this research is planning tool repair, checking each component, repairing or replacing damaged components, and preparing a guidebook that will later be used in the learning process. Modular Production System (MPS) that will be modified is divided into three modules namely the distribution, processing, and sorting station. Each module has sensors, fiber optic, proximity, and there is an opto-electric sensor. The Programmable Logic Controller (PLC) device to be used is Siemens with Totally Integrated Automation (TIA) Portal Version 15. Testing is carried out to test the feasibility of the tool the quality of the module, and whether it is still feasible and can be used in learning. As well as increasing students' knowledge and competence.

Abstract

Palm oil plantations are one of the important sectors in the growth of the economy in Indonesia. One of the palm oil plantation areas in the Pasaman Barat Regency is being developed with an estimated land area of 100 hectares. However, due to the location of the land being far from settlements, there is currently no electricity supply that can be used for the operational needs of the land. This research provides a solution for the planning of an Off-Grid solar power plant (PLTS). The method used is a descriptive method with a quantitative research type. Based on the calculations, the number of PV panels obtained was 14 units and produces a total power of 2.397,89 W, SCC capacity calculation obtained 35 A, Battery capacity 12V/100Ah 2 units, and inverter 3 kW to produce AC voltage. The calculation of the Bill of Quantities (BoQ) for material needs amounts to Rp. 21.986.000. This result indicates that the planning of the solar power system is feasible for the long-term operational needs of the plantation, which only requires initial construction capital.
