Abstract

This study focuses on power optimization of worker servers by applying live migration techniques for virtual machines (VMs) using the Mamdani fuzzy logic method. The main goal is to automatically move VMs to servers with lower CPU usage, thereby reducing overall power consumption. The system was built using the Proxmox VE platform and simulated for 30 minutes under two conditions: without and with Mamdani fuzzy logic. The results show that the use of fuzzy Mamdani reduces power consumption by 0.26 watts compared to the non-migration system. Although the savings may seem minor, the method is effective when applied at a larger data center scale. This technique enables efficient workload distribution by migrating VMs, allowing idle servers to reduce energy usage. In conclusion, Mamdani fuzzy logic offers a practical solution for energy-saving in cloud computing environments without compromising system performance.

Abstract

Improving environmental quality in architectural design is crucial in energy efficiency, health, and comfort, directly impacting occupant productivity. In tropical regions, high exposure to solar radiation significantly contributes to increased energy consumption in the building sector, accounting for 36% of total global energy usage. Shading devices are employed as a passive strategy to minimize solar heat gain, maintain thermal comfort, and evenly distribute natural light, reducing reliance on artificial lighting. This study analyzes the impact of different louver types on daylight optimization in shading devices, designed with the same module across various scenarios (louvers at ∠90°, ∠45°, and ∠150°). The research methodology involves computational simulations based on BIM, using Autodesk Revit for prototype modeling, parameter determination, scenario setup, and the Insight Plugin for simulating daylight illuminance (lux) and daylight factor (DF). The results show that the shading device with a 90° louver angle performs optimally in meeting the daylight illuminance standard (300–3000 lux) across various representative dates, achieving a daylight factor (DF) of 3.2%, in line with global standards. The louver angle significantly influences the overall distribution of natural light. This study's limitation is its focus on a single location (Surabaya) and its restriction to three shading device scenarios.

Abstract

The high unemployment rate among vocational school graduates, which reached 8.62%, reflects the gap between the purpose of establishing vocational schools as a creator of skilled labor and the real conditions in the field. This study aims to analyze the effect of using student worksheets (LKPD) based on the teaching factory model integrated with the science, technology, engineering, and mathematics (STEM) approach on the entrepreneurial readiness of vocational school students.Using a quantitative approach with a pretest-posttest design in a single group, this study involved eleventh-grade students majoring in electrical installation, focusing on solar power installation materials. The research instrument was an entrepreneurial readiness questionnaire covering six key indicators: self-confidence, task and result orientation, risk-taking, leadership, originality, and entrepreneurial readiness. The analysis results showed that the data were normally distributed based on the normality test with a value 0.05. Furthermore, the T-test results showed a significance value of 0.001, indicating a significant difference before and after the treatment. All indicators of entrepreneurial readiness significantly increased, with an average N-Gain score of 0.85, categorized as high. These findings confirm that the teaching factory-based learning model integrated with STEM is effective in improving students' practical skills, conceptual understanding, and readiness to face the workforce and build independent businesses. Therefore, this study recommends using teaching factory-based LKPD integrated with STEM as an innovative learning medium to enhance vocational students' entrepreneurial competencies

Abstract

Laboratories play a crucial role in enhancing learning experiences, verifying scientific concepts, and solving problems through scientific methods. However, the implementation of chemistry practicums in schools often faces significant challenges. This study aims to identify the problems hindering the implementation of chemistry practicums and propose alternative solutions to address these issues. A survey method was conducted using a qualitative descriptive approach. The population consisted of 45 schools in Aceh, involving 981 grade XII students. A cluster sampling technique selected 13 schools, comprising 80 participants, including principals, chemistry teachers, and students. Data were collected through validated instruments, including observation sheets, response questionnaires, interviews, and documentation. The findings revealed several obstacles, including inadequate laboratory infrastructure, unprepared teachers, insufficient tools and materials, limited supporting facilities, and a lack of laboratory staff. To overcome these challenges, alternative solutions were suggested, such as conducting practicums in classrooms through demonstrations, utilizing natural materials and virtual media, aligning practicums with learning standards, adopting blended learning models, and recruiting laboratory staff. These proposed solutions provide practical approaches to improving chemistry practicum implementation in public high schools, ensuring students gain hands-on learning experiences and enhancing their understanding of scientific concepts.

Abstract

This study is grounded in the fact that students learning outcomes in green chemistry are relatively low, which are attributed to conventional teaching methods that involve students only minimally. This study aims to investigate the effect of project-based learning implementation on enhancing students learning outcomes in the topic of green chemistry. A quasi-experimental design with a pretestposttest control group was employed. The participants were tenth-grade students at MAS Darul Ihsan, assigned to an experimental class using PjBL and a control class applying traditional instruction. Data were collected through cognitive achievement tests and student activity observation sheets. The data were analyzed using an independent t-test, yielding a significance level of 0.000. Findings revealed a significant difference in learning outcomes between the two groups, with the experimental class achieving an N-Gain score of 0.73 (high category), while the control class obtained 0.37 (medium category). These results demonstrate that the implementation of PjBL effectively enhances student engagement and conceptual mastery and awareness of the importance of green chemistry principles. Therefore, PjBL can be recommended as an effective instructional model to optimize learning outcomes and foster environmentally conscious attitudes among students
