This study examines the application of the Lagrange method and Particle Swarm Optimization (PSO) in solving the Economic Dispatch problem at the Tanjung Jati B Steam Power Plant (PLTU). The main objective is to compare the effectiveness of both methods in optimizing load distribution among generation units and to evaluate potential operational cost savings compared to actual operating conditions. The optimization model minimizes a quadratic generation cost function, subject to system load demand and the power output limits of each unit. Simulation data includes daily load distribution and fuel-related parameters such as calorific value and fuel price. The results show that the Lagrange method yields an average power output of 2,367 MW, equal to the real condition, while PSO produces 1,966 MW, which is 16.94% lower. In terms of cost savings, PSO achieves an average saving of IDR 938,501, while the Lagrange method and real operation yield average savings of IDR 1,078,064 and IDR 1,073,076 respectively. In percentage terms, Lagrange shows 12.95% higher savings than PSO and 0.46% higher than the actual condition. This study highlights the importance of integrating optimization methods in power plant operations to improve efficiency and reliability of electricity supply.

This study investigates how teaching methods affect students' willingness to learn. Students' interest and engagement in the learning process can be enhanced by effective teaching methods. Different teaching philosophies, including collaborative, inventive, interactive, and authoritative, have varying effects on students' willingness to learn. To achieve the best learning outcomes, it is necessary to choose a teaching style that suits the needs and characteristics of students. In this study, a qualitative approach was used to analyze students' perceptions of various teaching styles in the classroom environment. The results showed that interactive and collaborative methods tend to increase learning motivation more than the one-way authoritative style. In addition, teacher emotional involvement, the use of interesting learning media, and a conducive classroom atmosphere also contribute greatly to shaping students' learning interests. These findings are expected to be a reference in designing more adaptive and effective teaching strategies.

The project's findings indicate that the booklet received positive responses from respondents, with high average scores across its content, visual presentation, and ease of use. Consequently, this booklet is deemed suitable for use as an information and promotional tool for tourism within the Favehotel Hyper Square Bandung environment.

This literature review explores holistic approaches during pregnancy and their implications for midwifery practice. Holistic care addresses physical, psychological, social, and spiritual dimensions of maternal health, aiming to promote overall well-being and positive pregnancy outcomes. By synthesizing evidence from studies published between 2020 and 2025, this review highlights the benefits of integrating holistic methods such as stress reduction techniques, nutritional support, psychosocial counseling, and culturally sensitive care within midwifery. The findings suggest that holistic care enhances emotional resilience, reduces anxiety and depression, and strengthens the mother infant bond. However, challenges remain in standardizing holistic practices, ensuring adequate training for midwives, and overcoming systemic barriers. The review underscores the need for midwives to adopt a comprehensive, woman centered approach supported by ongoing education and interdisciplinary collaboration. Future research should focus on evaluating holistic interventions’ effectiveness and developing scalable models to improve maternal and neonatal outcomes globally. Ultimately, holistic pregnancy care offers a promising framework to enrich midwifery practice and support maternal well-being throughout pregnancy.

With technological advancements, digitalization in business has become a crucial factor in enhancing sales effectiveness, especially for micro, small, and medium enterprises (MSMEs). Toko Sakinah, which has been operating for nearly 35 years in Bengkalis, still relies on conventional sales methods, such as WhatsApp transactions or direct store visits. This approach limits market reach and operational efficiency. Therefore, this study aims to design and develop a web-based digital sales system using the Design Sprint method to improve sales effectiveness at Toko Sakinah.The Design Sprint method is applied to develop the system quickly and systematically, focusing on understanding user needs, prototyping, and testing solutions before full implementation. The result of this research is a sales website that facilitates online product ordering, sales reporting, and interaction between buyers and store owners. This website is expected to expand market reach, enhance sales efficiency, and serve as a development model that can be replicated by other MSMEs.

Marketing is the backbone of a business’s existence. Various ideas, creativity, and innovations in marketing continue to evolve in different forms. To attract a large number of consumers, some businesses engage in overclaim marketing. While this strategy may bring positive outcomes for some companies, it can also have negative consequences for others. One brand that has practiced overclaim marketing is Daviena Skincare. This study aims to analyze the impact of overclaim marketing on consumer trust in Daviena Skincare products. The research was conducted using a qualitative descriptive approach, with data obtained through digital tracing and observation. The findings indicate that overclaim marketing in the skincare industry, as practiced by Daviena Skincare, has negatively affected consumer trust. The overclaims identified include promises of instant results, false claims about premium ingredients, and unverified testimonials. An investigation by Doctor Detective revealed significant discrepancies between marketing claims and the actual product composition, such as Niacinamide, which was advertised at 10% but was not detected in laboratory tests. These findings contradict the marketed product benefits, leading to consumer disappointment and decreased brand loyalty. This phenomenon underscores the urgency for brands to be more transparent and ethical in their marketing strategies. Therefore, overclaim marketing practices must be eliminated to maintain the integrity of the industry and protect consumers’ rights to accurate information and products that align with their claims.
