Abstract

Using hands-on experiments in the classroom is a highly effective way to deepen students' understanding of theoretical concepts. By researching and developing a practical and cost-effective experiment using a pitot tube, we can transform the teaching of fluid mechanics from a content-based approach to one that promotes competency and practical application. The research includes exploring pitot tube theory, developing and evaluating the experimental design, simulating flow through the designed pitot tube using computational fluid dynamics simulation software, and implementing and evaluating learner satisfaction. The feedback we received from the students showed high satisfaction with the practical equipment used in the classroom and confirmed that this hands-on approach helped them achieve their learning objectives.

Abstract

To select an air purifier that fully meets the needs of consumers, this study was conducted to provide the most objective and effective suggestions in making decisions and evaluating different smart purifier options that suit the tastes of users. Such decision-making is complicated for non-professionals when there are countless large and small brands on the market today with many different prices, features, and incentives. In such complex situations, decision-making with TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) can be used to eliminate risk and to better represent the preferences of decision-makers. From modeling to using the Entropy method and the TOPSIS method, all are done to serve the ultimate goal of choosing a good air purifier that meets the needs of customers.

Abstract

Sustainable design plays a pivotal role in addressing environmental and social concerns within the field of architecture. This concept involves the integration of sustainability principles throughout the architectural design process, encompassing social sustainability, sustainable materials and construction methods, and sustainability assessment. Architects can create structures that demonstrate environmental consciousness, optimize resource use, promote social inclusivity, and preserve cultural significance by incorporating these fundamental principles. However, the successful implementation of sustainable architecture faces several challenges. These challenges include limited awareness among professionals, resistance to change in the industry, complexities in integrating sustainability, and budget constraints. Overcoming these hurdles necessitates comprehensive education, government support, adherence to regulations, technology utilization, and economic incentives to encourage the adoption of sustainable design techniques. Despite these challenges, the field of sustainable architecture holds significant potential for further advancement. Opportunities for exploration include integrating emerging technologies like artificial intelligence and machine learning, applying sustainable architectural principles in urban planning, advancing sustainable materials and construction methods, considering social sustainability, and developing comprehensive frameworks for holistic sustainability assessment. By advancing knowledge and innovation in these areas, sustainable architecture can contribute substantially to creating a more sustainable built environment. Architectural professionals, through collaboration, interdisciplinary approaches, and a commitment to long-term sustainability, have the potential to play a crucial role in shaping a sustainable future for urban areas and communities.

Abstract

The exponential growth of electronic waste (e-waste) has become a pressing concern. This alarming trend is expected to persist. The study identifies falling prices as a primary driver behind the surge in e-waste, making electronic devices more affordable and accessible globally. Developing countries, particularly in Asia, bear a significant share of this burden, as a burgeoning middle class with disposable incomes contributes to increased purchases and frequent replacements of electronic goods. Asia alone accounts for more than 40 percent of the global e-waste generated. The critical need for urgent and coordinated global efforts to address the escalating challenge of e-waste. It highlights the environmental hazards posed by improper disposal and the socio-economic impact on developing regions. As electronic consumption continues to rise, effective strategies must be implemented to mitigate the adverse effects of e-waste, emphasizing sustainable practices, responsible manufacturing, and international collaboration.

Abstract

The fate of women workers during the pandemic is quite worrying. The role of women's triple burden in these times is getting heavier. Mental workload is a multidimensional construct that demands attention, performance, and skills of workers according to their work environment. This study aims to find out the mental burden felt by female workers during the pandemic. The subjects of this study were female educators at the University of Balikpapan. Five subjects feel a Very high mental burden on work activities during a pandemic, namely subjects 06, 14, 19, 23, and 25. There are 18 subjects who feel a high mental burden including subjects 3, 4, 5, 7, 8, 10, 12, 13, 16, 17, 18, 20, 21, 26, 28, 29, 30, and 31. Then, 3 subjects felt a moderate mental load, and 2 subjects felt a low mental load. If average, then the mental workload of female educators at the University of Balikpapan is 56.623 categorized as high. This study also seeks to investigate the correlation between the perceived workload of the subjects and several factors including age, marital status, education level, address, family size, income, COVID-19 survivor status, and family members who are COVID-19 survivors. The result showed that the number of family members is the only significant factor that influences the mental workload.

Abstract

This study aimed to investigate the impact of problem-based learning with a focus on character development and naturalist intelligence on critical thinking (CT) abilities and curiosity of students. The study was conducted in a school in the city of Mataram - Indonesia, utilizing a 3x2 treatment by level design. Two groups of students, categorized as having high or low naturalist intelligence, were exposed to three different treatments: problem-based learning with character development (PBL-CD), problem-based learning, and regular learning. Data regarding the students' naturalist intelligence and CT abilities were collected through tests, while information on their curiosity was obtained through observation sheets and self-assessment. Statistical analysis using MANOVA at a significance level of 0.05 was performed. The findings revealed that: (a) PBL-CD had a positive impact on students' CT abilities and curiosity; (b) the naturalist intelligence did not significantly influence students' CT abilities and curiosity; and (c) there was no significant impact observed on students' CT abilities and curiosity when examining the interaction between PBL-CD and naturalist intelligence. Thus, PBL-CD presents itself as a viable strategy to cultivate students' critical thinking skills and inquisitiveness, offering an alternative pathway in routine learning in the classroom.
