Design of Knowledge Flow According to the Approach of Self-Regulation Learning for Teaching Maths on Chatbot

/in /by

Each student has different skills, interests, and learning paces in a classroom. If each student has a personal tutor to support learning according to their ability, it will improve the quality of teaching and no student will be left behind. In reality, no school has enough teachers to support individual learning, but each teacher has to handle many students in the same class. Therefore, an AI Chatbot that acts as a “virtual teacher” next to a real teacher can do that. AI Chatbot can support individual students in a friendly, interesting environment and provide knowledge depending on their cognitive level. Learning with AI Chatbot also helps students feel more interested and motivated with new learning methods. Instead of teachers providing information and knowledge for students to remember and apply, AI Chatbot will help learners build and create their knowledge through interactions and experiences. Besides providing answers to learners’ queries, Chatbots can provide step-by-step instructions to achieve teaching goals for specific lessons. In this article, the authors based on the applications of AI Chatbot in teaching to present a teaching scenario using AI Chatbot to teach mathematics with a self-regulated learning orientation for primary school students. Specifically, the authors have built a scenario for the “Millimeter” lesson in the Mathematics, 3rd Grade according to three phases of self-regulated learning: forethought, performance and self-reflection.

Funding Valuation to Support Disaggregation of Value Chain in HLMC Hospital Yogyakarta

/in /by

The economic cycle always goes through boom-and-bust cycles. When the economy slows down, the government will increase the money circulation; when the economy is heating up, the government will slow down the money circulation. In this regard, interest rates, credit control, currency policies, and so on play a role. The COVID-19 pandemic era accelerated the economic cycle relatively quickly. During the pandemic, the government provided massive stimuli to the economy, and during the recovery phase, the government tightened financial policies again. Such actions have made the global investment market experience tumultuous twists and turns. Corporate funding, which was relatively easier before, has become difficult. Companies once again have to adjust their business models to their original goals: value creation, generating profit and margin, and ultimately producing positive cash flow. Adapting to the changing demands of the business environment, shifting from a “growth at all costs” mindset to prioritizing “more sustainable profit,” companies must acknowledge that the essence of business activities is to generate real cash flow and tangible profits. This study compares different approaches to valuing companies: the Discounted Cash Flow (DCF), Revenue Multiple, and PE Multiples. DCF takes a valuation approach based on projections of the company’s future cash flows and real profits operationally, whereas revenue and PE multiples offer simpler valuation methods by emphasizing relative comparisons within similar industries. This simplification aids investors in evaluating potential profits when executing exit strategies. Therefore, the valuation method using DCF (Discounted Cash Flow) is not as aggressive as the valuation method using exit multiples, such as P/E (Price/Earnings) Multiple, let alone Revenue Multiple.  This research serves as a benchmark for the funding valuation method to support the disaggregation outlined by HLMC Hospital Yogyakarta in the field of skin, aesthetic, and wellness centers.

Coal is a valuable natural resource that belongs to the Indonesian state and serves as a crucial raw material for fulfilling the country’s primary energy requirements. Starting from 2022, the Government has made a formal declaration to attain Net Zero Emissions (NZE) by the year 2060. Presidential Decree no. 112 of 2022 has been issued to expedite the development of renewable energy for electricity supply. One of the consequences of this decree is the discontinuation of coal-based power plants, reflecting the government’s dedication to transitioning to alternative energy sources in the future. Sindo Energy (SE) is a mining contractor services company that operates under the Indonesia Mining Alliances (IMA). It specializes in the coal industry and has a significant market share, contributing to a Gross Profit Margin of 93.43%. Naturally, projects that collaborate with SE are firms that own coal and so have the power to influence the overall business operations. This study aims to offer a comprehensive and enduring perspective on the potential future occurrences of scenario planning. The fundamental basis for creating the four scenarios, namely Believing Spirit (BS), Pioneer of Changes (PC), Truly Fighter (TF), and Chameleon Specialist (CS), involves identifying the major focal issues, driving reasons, and sources of uncertainty. This research outlines four scenarios that depict the projected industrial conditions in 2040. Each scenario presents different ramifications and possibilities, as outlined in the study. This research also generates pre-emptive indicators for SE business, which will subsequently prove valuable for corporations in formulating strategic measures that the company can adopt to confront potential situations in the face of future uncertainty, via implementation plans spanning a minimum of 15 years, in the upcoming year.

Optimization of Ultrasound-Assisted Extraction of Bioactive Compounds from Peel Jambolan and Application of the Extract in Soy Protein Films

/in /by

Este trabalho teve como objetivo otimizar a extração de compostos bioativos de cascas de jambolão utilizando extração assistida por ultrassom e desenvolver filme ativo a partir de isolado proteico de soja e extrato de casca de jambolão. Para tanto, avaliou-se o efeito do tempo de processo e da concentração do solvente sobre compostos fenólicos totais, atividade antioxidante e bacteriana do extrato. A partir das condições ideais desses parâmetros, filmes foram preparados e o efeito da adição do extrato nas propriedades mecânicas, atividade bacteriana e capacidade antioxidante dos filmes ativos foram avaliados. Os resultados mostraram que a alta concentração de etanol reduziu a extração dos compostos bioativos com atividade antioxidante da casca de jambolão, entretanto, a interação entre o tempo de extração e a concentração de etanol apresentou efeito positivo na extração desses compostos. O extrato com ação bactericida contra Staphylococcus aureus e Escherichia coli não foi obtido em condições otimizadas. A adição do extrato reduziu a resistência à tração do filme de SPI, mas aumentou sua elasticidade e capacidade antioxidante. Os filmes de extrato SPI + afetaram a integridade da membrana celular bacteriana de Staphylococcus aureus e Escherichia coli. Filmes de SPI com extrato de casca de jambolão podem ser uma alternativa para limitar processos oxidativos indesejáveis e inibir o desenvolvimento bacteriano em alimentos embalados.
