This study aims to analyze user satisfaction with the PLN Mobile application using the Service Quality (SERVQUAL) method. PLN Mobile is a digital innovation from PLN, offering services such as electricity payment, token purchase, and e-commerce for electrical equipment. The SERVQUAL method assesses the gap between customers' expectations and perceptions across five dimensions: tangibles, reliability, responsiveness, assurance, and empathy. Data collection involved questionnaires focusing on users' perceptions and expectations, complemented by direct observations of user interactions with the application. The findings reveal negative gaps across all Service Quality dimensions, indicating that customer perceptions fell short of their expectations. The largest gap was identified in the assurance dimension (-23.2), followed by responsiveness (-16.88). The tangibles dimension also showed significant shortcomings (-8.48), mainly concerning the application's interface and functionality. While the application performed relatively well in terms of reliability and responsiveness, substantial improvements are needed across all dimensions to enhance user satisfaction. These results offer strategic insights for improving PLN Mobile to become more responsive, reliable, and aligned with user needs in the future.

The aim of this research is to determine the effect of supervision on employee performance at the Regional Technical Implementation Unit (UPTD) Pemembolum Senaken Market, Paser Regency. From the results of the validity test, all 10 statement items were declared valid because they were greater than the rtable value of 0.2006 for each statement in this study. From the results of the reliability test, a value of 0.959 was obtained, which means there is a very strong relationship between the independent variable and the dependent variable. From the results of multiple linear regression analysis, it can be seen that the results of the regression equation are Y = 40.597 + 0.535X1 + 0.361X2. Based on the calculation results, an R value (Correlation Coefficient) of 0.915 is obtained which is at an interpretation level between 0.80-1.00, which means that there is a very strong influence from the supervision variable (X) which consists of direct supervision (X1), and supervision. indirectly (X2), on employee performance (Y).

Renewable energy systems, particularly those incorporating solar and wind power, are prone to stability issues due to the intermittent and fluctuating nature of these energy sources. This paper investigates several nonlinear control techniques—namely, adaptive control, sliding mode control, and fuzzy logic control—that are designed to improve stability in renewable energy systems. Through simulations, we demonstrate how these methods can effectively reduce fluctuations and maintain stable energy output, offering a robust approach to enhancing the reliability of renewable energy systems.
