The Internet of Things (IoT)-based automatic bell system is designed to enhance the efficiency of bell operations in educational institutions by utilizing modern technology. This research aims to develop a system that can control the bell automatically according to the class schedule, while also enabling remote control via a mobile application using the Blynk platform. The system is built using an ESP8266 as the main microcontroller, a DFPlayer Mini module for audio playback, and an RTC DS1307 for time management. The results show that the system functions as expected, both in automatic mode based on the schedule and in manual mode through the mobile application. Testing and debugging demonstrated that integration with WiFi networks allows for flexible and effective bell control. For further development, it is recommended to add a power backup feature, web interface, and push notifications to improve system reliability and flexibility. This system provides an efficient and practical IoT solution for automating bell operations in educational environments.

Era 5.0 marks a societal shift towards deeper integration between humans and advanced technologies such as Artificial Intelligence (AI), Internet of Things (IoT), Big Data, and cloud computing. This article investigates recent developments in digital technology supporting Era 5.0, its impact on the business world, case studies of technology implementation, and challenges faced in transitioning towards this more connected era. Technologies like AI have transformed business operations by enhancing efficiency, personalizing services, and enabling more precise decision-making. Case studies from various sectors such as automotive, healthcare, and agriculture illustrate how companies adopt and integrate Era 5.0 technologies to create added value and maintain competitiveness. Despite the immense potential of Era 5.0, challenges such as data security, implementation costs, and organizational adaptation remain key focal points in executing this transformation. By considering these factors, the article underscores the importance of cross-sector collaboration, investment in skilled human resources, and awareness of ethical considerations in addressing challenges towards a more technologically connected society.

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.

The proliferation of the Industrial Internet of Things (IIoT) has transformed manufacturing, energy, and logistics, generating vast amounts of data that demand efficient processing solutions. Edge and cloud computing have emerged as two main architectures that can support IIoT applications by addressing latency, bandwidth, and computational challenges. This study presents a comparative analysis of edge and cloud computing architectures in the context of industrial IoT, focusing on performance, scalability, security, and cost. By analyzing case studies from manufacturing, logistics, and energy sectors, we identify the strengths and limitations of each approach, providing recommendations for selecting optimal architectures based on application needs.

This study focuses on how the portrayal of female power in one of Disney's films, Mulan. Film can provide a construct in socio-cultural reality. With this construction, the content of the film needs to be considered, because the content of the film can change the mindset of the audience who watches. Women are usually often complementary figures and do not have dominance than men. This is an interesting study because women can be constructed with the image above. Therefore, researchers dissect the portrayal of female power presented by Disney. Researchers use Ferdinand De Sausure's semiotic analysis method which focuses on signifiers and signified in interpreting women's power in Mulan. The supporting theory in this study is film as mass communication and women in the media. The results of the study showed three depictions of female strength from the film Mulan, namely women who are brave, women who resist and women who has a confident nature.

Human Resources is able to produce quality performance in a firm. To generate a high quality HR performance demands effective skill management, the variables that might affect the quality of HR performance are communication and work discipline that run simultaneously. The goal of this study is to determine and analyze the influence of communication and work discipline on employee performance, as well as to determine and analyze which of the two variables is the most dominating on the performance of Elisa Malang inpatient clinic staff. This topic has 47 respondents, employing sample collection technique is saturated sample research. Data collecting approaches using a questionnaire and Interviews. Data analysis with IBM SPSS Statistics. The results of this study can be stated that the factors of communication and work discipline have a simultaneous effect on the performance variable. The two communication factors have a significant but not significant effect on performance, while the work discipline variable has a significant effect. performance. And the results of the study also suggest that one of the variables has a more significant influence, namely the work discipline variable

Micro, Small, and Medium Enterprises (MSMEs) play a crucial role in the economy by creating jobs and fostering local economic growth. However, MSMEs, especially in the culinary sector, often face challenges in managing finances, including accurately calculating the Cost of Goods Manufactured (COGM). COGM, which includes raw materials, labor, and overhead costs, is essential for setting appropriate prices and maintaining profitability. Miscalculations can lead to inaccurate pricing, impacting competitiveness and profit margins. This study analyzes COGM calculations at U&Mie, a culinary MSME known for its chili oil chicken noodles, to understand its pricing strategy. Findings from this research and prior studies by Harefa and Purwanto reveal that the full-costing method provides consistent results, highlighting the need for comprehensive COGM calculations to avoid overlooking variables that could affect pricing. This study aims to offer guidance for MSMEs in managing production costs and setting prices effectively, enhancing their market competitiveness.

Early childhood plays an important role in forming the basis of development, which involves stimulation of various aspects such as moral religious values, social emotional, language, cognitive, and physical motor skills. The concept of early childhood learning is focused on play, where every activity is designed to be play, so that learning becomes more effective. Parents also need to understand today's children's education to interact with children positively. This research focuses on sentiment analysis of children's education-based app reviews on the Google Play Store, using Random Forest and Logistic Regression methods. The review data is taken from three apps with the theme of child development, namely "About Kids", "PrimaKu", and "Teman Bumil", with a range of review years between 2018 and 2023. The test results show that Logistic Regression has higher accuracy compared to Random Forest, especially in the "About Kids" and "PrimaKu" applications with accuracy above 90%. The conclusion of this research highlights the importance of sentiment analysis in improving understanding of user responses to children's education applications, with suggestions for future research to increase the number of datasets and variations in testing schemes by tuning hyperparameters to improve prediction accuracy and more optimal results.
