Abstract

A mismatch in the output power of photovoltaic (PV) modules in a PV array can occur due to partial shading or a module replacement. Substitution of a module in a PV array with a new one might lead to different current and voltage characteristics between the new and existing modules and result in power losses. The amount of power loss might be increased more if the PV array experiences partial shading. For this reason, this study aims to investigate the effect of partial shadings on the power output of photovoltaic arrays with different current and voltage characteristics. The PV array under test consists of 25 units of solar modules with a total cross-tied (TCT) configuration. There are five shading conditions applied to the test PV array, i.e., the short narrow (ShN), the short wide (ShW), the long narrow (LnN), the long wide (LnW), and the diagonal. A magic square method is applied to reduce the power loss when the PV modules experience partial shading conditions. The results show that the power loss due to partial shadings, either on all identical modules or partially identical, is the same. The most significant power loss occurs in the long comprehensive shading scenario, where 80% of the modules experience shading, which is 41.30%.

Abstract

The regulation of the legal position of Deputy Regional Heads in the implementation of Regional Government has undergone dynamics. Law Number 32 of 2004 has further clarified the position of Deputy Regional Heads in a more concrete manner. Especially with the election of a single pair with the Regional Head, it shows that the role of the Deputy Regional Head is becoming stronger in the implementation of Regional Government. This research uses a descriptive juridical method. The results of this study show that the regulation of the position and duties of deputy regional heads in the structure of regional government has undergone different regulatory dynamics in several laws. Their position as a local government official elected directly by the people as a running mate with the regional head strengthens their position in the structure of regional government. Although their duties are primarily to assist the regional head in the implementation of regional government, in certain situations, the deputy regional head can replace the regional head when the regional head is unable to perform their duties.

Abstract

In reality, lawyers as Legal Enforcers in Criminal Cases still face obstacles, both internally and externally. Therefore, efforts to optimize the role of lawyers in criminal cases involve providing services to the public without discrimination. This research uses a descriptive juridical method. The results of this study indicate that efforts that can be made to optimize the implementation of the lawyer's function in criminal cases are as follows: Lawyers must be aware of and fulfill their primary duties and functions in providing legal assistance to the public without discrimination. Law Enforcement Officials (Police, Prosecutors, Judges) as legal enforcement partners should provide positive support to lawyers so that they can fulfill their primary duties and functions in providing legal assistance to the public without discrimination.

Abstract

Customers receive their electricity from distribution transformers; a disturbance will interfere with this process. High harmonics are typically the source of issues in distribution transformers. The distribution transformer at PT. PLN (Persero) ULP Syiahkuala has two issues: the neutral cable breaking and the main or secondary winding burning. Analyzing harmonics in distribution transformers at PT PLN (Persero) ULP Syiahkuala is the goal of this study. The goal of this study is to measure, examine, and assess the transformers at Syiahkuala ULP in order to select the best mitigation. One transformer's harmonic values were determined by the measurement findings to be out of compliance with requirements, necessitating the use of a variety of passive filters to reduce themThe results of THDi reduction using a passive filter are the values obtained for each phase R, S, and T. These values are in accordance with the established standards. From the results of harmonic mitigation using a passive filter, the results obtained in accordance with the THDv and THDi standards based on IEEE 159-2014 are 8% and 10%, respectively.

Abstract

Energy consumption (kWh) is critical to the operation of electrical systems. Predictive modeling optimizes energy usage, increasing power system efficiency. This study created an artificial neural network (ANN) architecture to estimate energy consumption (kWh) for home users in Banda Aceh. The ANN topology consisted of 5 input layers, 5-25 hidden layers, and one output layer. This study used two scenarios: first, the ANN topology was trained using the logsig activation function, and then the tansig activation function was used for training. Based on training simulations, the ANN architecture with 5 input layers, 5 hidden layers, and 1 output layer has the lowest Mean Squared Error (MSE) of 0.00035. The next phase involved testing this ANN topology. The next stage is to analyze the ANN architecture with 5 input layers, 5 hidden layers, and 1 output layer using the testing technique. Based on the testing technique, the ANN architecture with 5 input layers, 5 hidden layers, and 1 output layer had a MAPE value of 3.34%.

Abstract

The rapid development of digital technology has significantly influenced the educational landscape, including the teaching of Islamic Religious Education (PAI) at the elementary level. One of the most widely used platforms with great potential for supporting learning activities is YouTube. This study aims to analyze how YouTube can be effectively utilized as a learning resource to enhance students’ interest in Islamic Religious Education. The research employs a library research method by reviewing relevant literature, scientific articles, and digital sources related to the topic. The findings reveal that YouTube’s visual and auditory strength can effectively capture students’ attention, making learning more interactive and meaningful. This platform enables teachers to connect Islamic values with real-life contexts through engaging digital presentations. However, its effectiveness largely depends on the teacher’s ability to select and guide content aligned with the goals of Islamic education. The study concludes that YouTube functions not only as a visual aid but also as a transformative medium that bridges students’ digital world with moderate and humanistic Islamic values. This research contributes conceptually to developing adaptive models of religious education in the digital era and promotes digital literacy among Islamic education teachers.
