The purpose of writing this review article is to analyze the formulation and evaluation of the use of various additives in effervescent tablets. The method used is a literature review taken from journals and other relevant research results regarding the formulation and evaluation of additives in various types of effervescent tablets. The purpose of this analysis is to provide a summary of relevant publications and to improve current understanding in this field. The importance of the formulation and evaluation of additives in effervescent tablets cannot be ignored, because it is a crucial aspect in product development. Decisions in the use of additives must consider the objectives to be achieved, the desired physical characteristics, product stability, and the level of consumer acceptance. With a deep understanding of this formulation and evaluation, we have the potential to produce high-quality effervescent tablets.

This study develops an image processing application to automatically detect the ripeness level of tomatoes using the YCbCr color space transformation. This method is effective because it is able to separate the luminance and chrominance components, so it can identify color changes that indicate the ripeness level of tomatoes, namely unripe, semi-ripe, and ripe tomatoes. The application is designed with matlab and uses a GUI interface that makes it easy for users to upload and process images. Based on trials on image samples, the system is able to classify tomato ripeness with 100% accuracy on a limited test dataset. The classification process is based on three main parameters: the red area ratio, the average value of the Cr channel, and the average value of the Cb channel. The results of the study indicate that this approach can be used as a digital solution in the automatic and efficient tomato sorting process

This study uses a qualitative method to examine the effectiveness of marketing strategies implemented by Islamic banks in attracting young customers. The background of this research is based on the significant growth of the Islamic banking sector in Indonesia, which has not yet fully optimized the potential of the youth market segment. Data were collected through in-depth interviews with marketing managers and young customers, as well as documentation of the promotional strategies employed. The findings reveal that marketing strategies emphasizing Islamic values, service digitalization, and social media campaigns significantly influence young customers’ interest. However, some challenges were also identified, such as low Islamic financial literacy among the youth and limited product innovation tailored to their needs. This study recommends strengthening Islamic financial education, collaborating with youth communities, and developing technology-based products and services so that Islamic banks can be more competitive in attracting young customers. With a more adaptive and communicative approach, Islamic banks have the potential to become the preferred choice for the younger generation in the future.

The study suggests that elderly services should not only focus on physical needs, but also on psychosocial dimensions and self-actualization, to support the overall well-being of the elderly.

The use of Artificial Intelligence (AI) has now become one of the crucial aspects in the advancement of information technology throughout the world. This article aims to connect the values ??of Pancasila as the moral basis of the Indonesian nation with the ethics of using artificial intelligence and its impact on the country. As the philosophical foundation of the state, Pancasila contains deep ethical values ??and can be used as guidelines in the application of AI that are in line with the moral and ethical principles that apply in Indonesia. Pancasila education has an important role as an ethical framework in the context of the development and application of AI. In this article, we will discuss the application of Pancasila values ??in technological developments so that they remain in line with the nation's identity, as well as explore the various positive and negative impacts that may arise from the use of AI. Furthermore, this study seeks solutions that can be implemented by the government, companies, and society to overcome these negative impacts. Using a descriptive qualitative approach, this study aims to explore and understand in depth the relationship between Pancasila values ??and ethics in the use of AI, especially in the context of the development of information technology in Indonesia. This approach is very appropriate for examining social phenomena, values, and meanings contained in policies or implementation of technology in society.

This study aims to examine the effect of liquidity, profitability, and solvability ratios on investment decisions while also investigating the moderating role of firm size in this relationship. The research focuses on manufacturing companies listed on the Indonesia Stock Exchange for 2019-2023, which are marked by significant economic disruptions, including the COVID-19 pandemic. A quantitative approach was employed, using panel data regression to test the proposed hypotheses. Financial ratios were measured using the current ratio, return on assets, and debt-to-equity ratio, while investment decisions were assessed using the price-earnings ratio. The natural logarithm of total assets measured firm size. The results reveal that liquidity and solvability significantly influence investment decisions, while profitability does not. Firm size was found to moderate the relationship between liquidity and solvability with investment decisions, but not the relationship involving profitability. These findings have practical implications for investors and corporate managers in formulating investment strategies and managing financial performance, highlighting the importance of considering firm size when evaluating the effectiveness of economic indicators. This research also contributes to the empirical literature on investment decision-making in the manufacturing sector.

In the era of globalization and rapid technological development, critical and creative thinking skills are important competencies that must be possessed by students to face real-world challenges. The learning strategy for improving thinking ability (SPPKB) is a learning approach that focuses on developing students' thinking skills through the analysis of facts or experiences and active problem solving. This learning model involves stages of onboarding, experience tracking, problem confrontation, inquiry, accommodation, and transfer to guide students to discover concepts independently and apply noble values such as honesty. In addition, this strategy demands active student involvement, increased motivation, and the use of technology and discussion methods to create a conducive learning environment. Although it has advantages in developing critical thinking skills, this strategy also faces challenges such as the need for sufficient time and the readiness of teachers and students in its implementation. With the right implementation, this learning strategy can increase students' thinking potential optimally and is relevant to the demands of modern education.

Abstract: This study aims to develop students’ 6Cs skills—critical thinking, creativity, communication, collaboration, character/compassion, and citizenship/culture—through the implementation of Project-Based Learning (PjBL) in a program titled Masyarakat Belajar Sejarah (History Learning Society). The research responds to the relatively low competitiveness of students in East Kalimantan amid the challenges of the 21st-century VUCA world, Indonesia’s demographic bonus, and the development of the new national capital (IKN) in East Kalimantan. Using Kemmis & McTaggart’s action research model, the study involved students from the History Education Program, FKIP, Mulawarman University, across three cohorts (2020–2022). Data was collected through observation, documentation, questionnaires, and interviews in March and June 2023. Students collaborated with schools, non-formal institutions, professionals, and local communities in Samarinda to design creative, contextual historical learning products. The findings show significant improvements across all 6Cs indicators. The project enhanced students’ academic and social competencies and bridged the gap between classroom learning and real-life community engagement. The results highlight the potential of PjBL as a transformative learning strategy for equipping future educators with essential 21st-century skills. This research contributes to history education innovation by positioning students as agents of change within their communities.
