The phenomenon of online loans has emerged as a financial innovation that transforms the pattern of access to funds within urban communities. The convenience of obtaining loans without complex requirements has contributed to the rise of a consumerist lifestyle, especially among the younger generation. This study aims to analyze the correlation between the use of online loans and the dynamics of consumerist lifestyles in urban society. By employing a literature review and descriptive-qualitative analysis methods, the research reveals that low financial literacy, social pressure, and the influence of social media intensify the tendency toward instant loan-based consumerist behavior. Psychological factors such as FOMO (Fear of Missing Out) and the philosophy of YOLO (You Only Live Once) further reinforce this consumerist behavioral pattern. The results of the study show that the phenomenon of online loans not only impacts financial issues but also causes psychological stress and shapes compulsive consumption patterns.

The transformation of journalism in the digital age has led to the emergence of local online media platforms operating without formal editorial structures. This study investigates the news production process of a public service article published by a semi-professional online portal, focusing on how editorial routines are adapted—or bypassed—in decentralized environments. The selected article, which listed hospitals affiliated with the national health insurance program, was widely circulated yet contained factual inaccuracies that impacted readers' real-life service access. Using a qualitative case study design, the research draws on interviews with the editor, observational data, document analysis, and reader responses. The results reveal a linear, individualized editorial workflow in which a single actor handled all stages of production without verification protocols. Visual design elements such as structured layouts and official-like typography were employed to simulate credibility, resulting in what this paper terms aesthetic misinformation. While the article was produced to serve the public, the absence of institutional oversight contributed to its unreliability. The findings contribute to media and communication studies by highlighting the tension between visual legitimacy and journalistic integrity in grassroots media production. The study recommends adopting lightweight editorial standards and reflexive design practices to promote ethical information dissemination in non-institutionalized news environments.

Forecasting the number of electricity customers is a crucial aspect of resource planning and management at PT PLN Tasikmalaya. One method that can be used to improve forecasting accuracy is Lagrange Interpolation, which constructs an interpolation polynomial based on known data points. Although this method has been widely applied in various fields, its use in forecasting the number of electricity customers remains rare. Therefore, this study aims to explore the application of the Lagrange Interpolation method in forecasting the monthly number of electricity customers at PT PLN Tasikmalaya.In this study, historical electricity customer data was used as the basis for constructing an interpolation polynomial, which was then utilized to forecast the number of customers from January 2024 to May 2024. The forecasting results indicate an increase in the number of electricity customers each month. After rounding, the estimated number of customers is 274,952 in January 2024, 278,142 in February 2024, 284,402 in March 2024, 296,031 in April 2024, and 316,391 in May 2024.The findings of this study demonstrate that the Lagrange Interpolation method can be applied to forecast the monthly number of electricity customers at PT PLN Tasikmalaya.

This study uses a qualitative method with a literature review approach to examine the effectiveness of the two-phase method in solving linear programming problems. The two-phase method is one of the techniques in linear programming used when the objective function does not have a feasible initial solution directly. Through the exploration and analysis of various scientific literature sources from 2019 onwards, this study finds that the two-phase method can systematically provide optimal solutions, especially in complex problems with multiple constraints. Previous research has shown that this method is effective in accelerating the identification of basic feasible solutions and minimizing unnecessary iterations compared to the standard simplex method. Additionally, the two-phase method offers better numerical stability and high reliability in both industrial and educational applications. However, its effectiveness largely depends on the understanding of the algorithm and the ability to design an appropriate mathematical model. The results of this study are expected to contribute theoretically to the development of efficient solution techniques for linear optimization problems.
