Abstract

Mathematical thinking skills are high-level thinking competencies needed in the 21st century. Many physics problems are expressed in various forms of mathematical equations that require mathematical thinking skills. The low level of mathematical thinking has an impact on physics learning outcomes. Cramer’s rule is more attractive to students when solving the Linear Equation System (LES) than the substitution method or other methods. So this study aims to examine the effectiveness of Cramer’s rule on the system of linear equations of 2-loop electrical circuits as an alternative solution to problem solving. The research was conducted in the odd semester of 2024/2025 with research subjects as many as 44 students and 30 high school students in Jember using Pre-Experimental Design and One Group Pretest-Posttest form. The results showed the improvement of college students’ mathematical thinking skills in the high category for indicators of specializing (72.7%), generalizing (95.5%), and conjecturing (86.4%) while the convincing indicator was in the medium category (65.9%). The improvement of college student learning outcomes (79%) and high school students (81%) in the high category with a very positive response or 82.14%. So Cramer’s rule is effective in improving mathematical thinking skills and learning outcomes.

Abstract

Learning innovation is needed to make the learning process more attractive and improve student learning outcomes. Learning outcomes can be improved by making learning more interesting and developed according to student needs. Learning materials are packaged with different problem-solving methods that make learning more interesting to improve student learning outcomes. Based on existing findings, students' mathematical thinking skills are still relatively low. This study aims to measure the effectiveness of applying Cramer's rule to improve mathematical thinking skills and learning outcomes. This study uses a quantitative descriptive method which was carried out at Jember State High School and the Physics Education Study Program, Jember University in the odd semester of the 2024/2025 academic year. The results of data analysis from mathematical thinking skills affect the success of physics learning. The results of the homogeneity test and normality test that have been carried out show that the samples used are homogeneous and normal. The N-Gain value is obtained in the high category for improving mathematical thinking skills and learning outcomes. And the student response is very positive towards the use of Cramer's rule in solving the system of linear equations on the fixed pulley material. So it can be concluded that Cramer's rule in solving linear equation systems on pulley material remains effective in improving mathematical thinking skills and learning outcomes.

Abstract

This research aims to analyze the influence of organizational citizenship behavior (OCB) on performance through knowledge sharing at RSPAU Indonesia. This research was conducted in RSPAU Indonesia, located in the Adi Sutjipto Air Base office complex in Yogyakarta. The population of this research is all operational members of medical, nursing and other health personnel of RSPAU in Indonesia who are based on experience. At the same time, they are on duty, so they can assess OCB and measure knowledge sharing and performance. The sampling technique used was proportional random sampling, so the sample size was 167 samples of RSPAU Indonesia members from a population of 923. The data collection procedure in this research is to use a questionnaire, which will be analyzed using descriptive analysis. The research results show that voluntary Behavior is performed by members of an organization outside of specific tasks but contributes to the organization's overall effectiveness. Meanwhile, knowledge sharing is a process where individuals or groups share knowledge, experience and information with other people. The performance results are obtained by organizations or individuals when achieving organizational goals. Knowledge sharing as an intervening variable also mediates the performance of the OCB on staff. OCB has a significant influence on staff performance if met diated by knowledge sharing. I hope this research explains the success of RSPAU Indonesia in anticipating the dynamics of rapid changes in the world of health after the COVID-19 pandemic with its various complexities and problems. This research contributes to hospital leaders improving staff performance by looking at the influence of OCB on improving performance, both directly and indirectly, through knowledge sharing.

Abstract

The existence of BPJS makes healthcare services affordable for the community in Indonesia. Nationally, more than 95% of BPJS participants indicate that the public has confidence in BPJS, which supports the formation of loyalty. JKN participants in Malang Raya reach > 90% of the total population, but there are still inactive independent participants >20%. This situation demands that BPJS be able to maintain the sustainability of the JKN program, which can ensure the continuity of health financing. As an appropriate effort, it is to increase the loyalty of independent participants. The type of this research is Explanatory Research that analyzes the influence of E-Servqual and brand image on loyalty mediated by trust in Malang Raya. The population in this study consists of 618,893 JKN PBPU participants in the Malang Raya area, with a sample size of 200 participants. Data were obtained using a questionnaire and the Google Form application. The descriptive research results show that 100% of respondents agree that E-Servqual, brand image, and trust contribute to loyalty. The hypothesis test of the direct influence of E-Servqual on loyalty proved to be insignificant, but brand image has a significantly positive effect on loyalty. In the indirect influence of E-Servqual on loyalty, mediated by trust, it was proven to be significantly positive, whereas the indirect influence of brand image on loyalty, mediated by trust, was not significant. The results indicate that JKN participants have received services as expected through electronic services (E-Servqual), the image of the BPJS organization is perceived as good and of high quality, thus respondents trust and remain active BPJS participants. Based on the discussion, it is recommended that BPJS increase attention to the issues experienced by JKN participants through the website, as well as respond to participant complaints and periodically evaluate the website.

Abstract

The low learning outcomes of students in physics lessons are one of the main challenges in education. One of the reasons behind this low achievement is the lack of teaching materials available in schools. The purpose of this research is to improve student learning outcomes for the implementation of learning modules at SMA Negeri Arjasa. This type of research is quantitative descriptive with a One Group Pretest-Posttest Design. The sample used was 60 students. The results showed that in class XI 2 that applied the Cramer rule, the average posttest result was 84.87 and the pretest result was 49.53. A similar thing was found in class XI 4 with an average posttest result of 86.9 which was better than the pretest result of 55.8. The increase was analyzed using the N-Gain Score through SPSS 25 to get an average of 0.7 including the high category. The learning outcomes of students who applied Cramer's rule and the inverse matrix method showed a better improvement compared to the learning outcomes of students before being treated with both methods in solving fixed pulley problems

Abstract

Swimming pools integrated with the main structure are increasingly popular in modern high-rise buildings due to their aesthetic appeal and recreational value. As a result, there has been much research into the influence of swimming pools, which were previously considered as additional masses, now function as passive dampers, Tuned Liquid Dampers (TLD). The focus of the research is the optimal placement of the swimming pool position because the swimming pool can increase the eccentricity to the center of mass, which affects the dynamic behavior of the building. This study analyzes the position of the swimming pool to affect the TLD's effectiveness in reducing the drift ratio. The study was conducted numerically with ETABS at a 10-story hotel with two basements and a total building height of 39.6 meters. The swimming pool measuring 16.25 x 4.85 x 1.5 meters was analyzed in empty conditions and two positions, namely Pool P1 (existing pool) with a mass eccentricity of 20.679 m. In contrast, pool P2 is a pool with a position that is moved closer to the center of mass, with a mass eccentricity of 10.650 m. The swimming pool is modeled with a spring-mass model as a dynamic load, and the damping ratio is 5%. The analysis used the mass spectrum response method based on SNI 1726:2019.

Abstract

Tuned Liquid Damper (TLD) is a control system used to reduce structural vibrations in buildings or other structures (Hochrainer & Ziegler, 2006). One innovative use of this control system is a rooftop swimming pool (JIN et al., 2023). Research on utilizing pools as TLDs has been conducted, but no study has specifically focused on selecting the optimal depth of a rectangular rooftop swimming pool in irregular buildings. This study aims to analyze the influence of the selection of rooftop swimming pool depth on an irregular building structure's deflection. The analysis was conducted using ETABS, with the object being a 10-story hotel building with 2 basements. The existing swimming pool, measuring 16.25 x 4.85 meters and located on the rooftop, was analyzed with 3 different depth variations. The swimming pool was modeled using a spring mass model as a dynamic load according to ACI 350.3-2020. The analysis was carried out using the response spectrum method with parameters based on the building's location. The analytical findings reveal that the swimming pool depth can influence its performance as a tuned liquid damper (TLD) in an uneven building construction. The research revealed that model 3 had the least maximum displacement, with a reduction of 2.72% in the x-direction and 3.27% in the y-direction. It can be inferred that in the examined building, a swimming pool with a depth of 2 meters (model 3) is more successful at decreasing displacement, particularly in the y-direction.

Abstract

The 5.0 era has introduced substantial transformations in accounting practices through the incorporation of advanced technologies, including artificial intelligence (AI), big data, and automation. These technological advancements provide enhanced efficiency and precision in financial data processing and analysis; however, they also present challenges in upholding fundamental accounting principles such as transparency, integrity, and accountability. This article analyzes the integration of technology with humanistic accounting ideals in the digital age via the lens of the philosophy of science, namely positivism, interpretivism, and pragmatism. Additionally, the article discusses the importance of ethics in accounting in the 5.0 era, emphasizing the application of virtue ethics theory and discourse to ensure that accounting decisions continue to consider relevant moral and social values. This paper advocates for a decision-making framework in accounting that emphasizes fairness, transparency, and social responsibility, notwithstanding the efficiency offered by technological advancements.
