Corrosion in materials is a significant concern for the industrial and academic fields because corrosion causes enormous losses in various fields such as the economy, environment, society, industry, security, safety, and others. Currently, material damage control using organic compounds has become a popular field of study. Pyridine and quinoline stand out as corrosion inhibitors among a myriad of organic compounds because they are non-toxic, inexpensive, and effective in a variety of corrosive environments. Experimental investigations in developing various candidate potential inhibitor compounds are time and resource-intensive. In this work, we use a quantitative structure-property relationship (QSPR)-based machine learning (ML) approach to investigate support vector machine (SVR), random forest (RF), and k-nearest neighbors (KNN) algorithms as predictive models of inhibition performance. (Inhibition efficiency) corrosion of pyridine-quinoline derivative compounds as corrosion inhibitors on iron. We found that the RF model showed the best predictive ability based on the coefficient of determination (R2) and root mean squared error (RMSE) metrics. Overall, our study provides new insights regarding the ML model in predicting corrosion inhibition on iron surfaces.

The integration of Environmental, Social, and Governance (ESG) metrics into performance evaluation has become increasingly vital in achieving corporate sustainability and competitive advantage. This study investigates the impact of ESG metrics on organizational performance within the framework of strategic management accounting (SMA). Using a quantitative approach, secondary data were collected from ESG reports of 100 publicly listed companies across various industries. The analysis employs multiple linear regression to examine the relationships between ESG dimensions—Environmental, Social, and Governance—and financial performance indicators, including Return on Assets (ROA), Return on Equity (ROE), and Tobin’s Q. The results reveal a significant positive correlation between ESG scores and financial performance, with the Environmental dimension exhibiting the strongest influence (? = 0.45, p < 0.01), followed by Social (? = 0.30, p < 0.05) and Governance (? = 0.25, p < 0.05). Firms with high ESG scores (?75) reported 15% higher ROA and 20% higher ROE than those with lower scores. These findings underscore the importance of integrating ESG into SMA practices to enhance transparency, stakeholder trust, and sustainable decision-making processes. This study contributes to the literature by providing a comprehensive evaluation framework that aligns ESG metrics with corporate objectives. Practical recommendations include adopting global ESG standards, improving transparency in ESG reporting, and prioritizing strategic initiatives in sustainability. Future research could explore the long-term effects of ESG integration on non-financial outcomes, such as brand reputation and employee satisfaction.

Purpose: The main objective of this research is to develop a fall detection system and improve rapid emergency response or early warning systems for falls in the elderly.
Methods: In this research, the waterfall method was used for image analysis to detect falls with high accuracy. We also used Raspberry Pi 3, and OpenCV3 to set up a server to receive fall detection alerts and forward them to email.
Results: This system integrated a camera mounted on a Raspberry Pi 3 to continuously monitor the area captured by the camera. In the fall detection system, the results of testing with data showed that the system accuracy was 72.22%, sensitivity 72.72%, and error 27.77%.
Novelty: The approach this research adopted can be used in a variety of settings, including home healthcare, elderly care facilities, or places that require safety monitoring. With this system, we hope to improve rapid response in emergency situations, thereby protecting and improving the quality of life for people in need.

Abstrak:
In the world of education, learning difficulties are a complex problem that can have a significant impact on student academic achievement. Analysis of causal factors and solutions is important in understanding these dynamics. Factors that cause learning difficulties include health conditions, learning environment, and individual characteristics of students. The impact of learning difficulties can be felt in declining grades, emotional disturbances, and limitations in developing students' potential. However, through the right approach, solutions can be found. Solutions such as learning differentiation, additional support programs, and partnerships with parents are key in helping students overcome learning difficulties and improve their academic performance. These steps provide opportunities for all students to reach their optimal learning potential. This research explores in depth the relationship between learning difficulties and academic achievement, and analyzes the underlying causal factors. Through a better understanding of these issues, educators, education professionals, and parents can work together to create learning environments that are inclusive, supportive, and facilitate students' holistic development. This will have a positive impact in improving student learning outcomes and preparing them for success in the future.

Ring of Fire and at the intersection of three tectonic plates. Efforts are needed to minimize earthquake damage, one of which is the use of a base isolator system. This study aims to determine the effect of using High Damping Rubber Bearing (HDRB) with a diameter of 800 mm on the behavior of reinforced concrete structures in tall buildings under seismic loads. The research location is the 7-story Sapadia Hotel building in the city of Mataram. The research is conducted by analyzing a 3D model of the fixed base structure and the base isolator structure using numerical analysis. The results show an increase in the base displacement of the base isolator structure by 59% in the x-direction and 44% in the y-direction, while the inter-story displacement decreases by 36% in the x-direction and 69% in the y-direction. The use of base isolators can reduce the shear force by 35% in the x-direction and 15% in the y-direction. Based on the pushover analysis, the roof displacement values for the fixed base and base isolator structures are 0.159 m and 0.129 m respectively. These values can be used to determine the structural performance level according to ATC-40. The maximum drift value for the fixed base structure is 0.0055 m. For the base isolator structure, the maximum drift value is 0.0044 m, categorized as Immediate Occupancy (IO). This value can be used to determine the performance level of the structure based on ATC-40. The maximum drift value of the fixed base structure is 0.0055m. While in the base isolator structure, the maximum drift value is 0.0044 m which is included in Immediate Occupancy (IO). Thus, the use of base isolators in high-level buildings is able to reduce post-earthquake damage and the building is still safe to continue using.

The diversity in societal exercise preferences has increased significantly, with fitness emerging as a favored modern activity, particularly in urban areas of Indonesia. Fitness is valued for its effectiveness in restoring body fitness and achieving ideal body shapes swiftly. However, in the era of Industry 4.0, technological advancements have revolutionized the approach to fitness. Smartphone fitness applications have replaced the role of personal trainers by providing tailored exercise and dietary programs. User Interface (UI) plays a pivotal role in fitness applications, influencing User Experience (UX). The challenge lies in designing UI to accommodate user heterogeneity, both internally and externally. Adaptive UI emerges as a solution, capable of altering layout and content according to user characteristics. Kernwerk® Functional Fitness exemplifies a fitness application utilizing AI to optimize fitness routines. To enhance Kernwerk's UI adaptability, UX evaluation is conducted using UEQ+ modular extension, a comprehensive instrument for effectively and efficiently measuring user experience. Through this evaluation, components of UI and UX requiring further development to enhance Kernwerk's adaptability can be identified.
