Rice husks are agricultural waste whose utilization is not optimal because the waste is usually only burned. Agricultural waste that is burned will harm the environment. Chemical contents such as cellulose and lignin in rice husks can be used to make active carbon. This research aims to determine the optimum operating conditions for producing carbon, obtain information regarding functional groups and changes in pore surface area on carbon before and after activation, and determine the effect of chemical activator HCl on the carbon produced. Rice husks were carbonized using a furnace at temperatures of 200°C, 250°C, and 300°C for 30, 60, and 120 minutes, followed by chemical activation using HCl for 12, 24, and 36 hours. The research results showed that the carbonization variation of 300°C at 120 minutes was closest to SNI standards: water content of 3.91%, ash content of 14.63%, volatile content of 20.01%, and fixed carbon content of 65.36%. Activation of HCl causes the appearance of carboxylic acids. Chemical activation of HCl for 12 hours resulted in proximate content that was close to the SNI 06-3730-1995 standard and resulted in the husk carbon having a larger pore surface area, namely 141,369 m2/g, compared with the pore surface area of the husk carbon before activation was 118,083 m2/g.

The research follows an associative approach with a causal relationship form and utilizes a quantitative method. The population and sample for this research include all Regional Apparatus Work Units (SKPD) in Sikka Regency. Data was collected through a questionnaire distributed to each SKPD, with a total of 72 respondents. The data analysis involved multiple linear regression analysis using the Statistical Package for the Social Sciences (SPSS). This research showed that the significance value of X1 is 0.004, which is lower than the significance level of 0.05 (0.004<0.05) with a t-value of 2.989. Similarly, the significance value of X2 is 0.000, also lower than the significance level of 0.05 (0.000<0.05) with a t-value of 4.365. Additionally, the F-test yields a significance vale of 0.000, which is less than the specified significance level of 0.05 (0.000<0.05) with an F-value of 36.690. Therefore, it can be concluded that both the Internal Control System and Regional Financial Supervision significantly impact the Reliability of Financial Report Presentation, both individually and simultaneously.

Abstrak:
In light of the increasing degree of competition in the international business environment resulting from the technological changes that have occurred recently, which has made companies rely on elements through which they can increase the companies’ capabilities to compete and achieve what they aim for, and for this reason the human element (human capital) was the factor. It is decisive in increasing productivity and companies’ abilities to compete in light of the changing and evolving business environment, as the research showed that there is a major role for human capital in increasing the financial performance of the research sample (Al-Janoob Islamic Bank) and achieving high profit levels as a result of that company’s acquisition of competent and skilled human capital. The research compared two different periods in terms of the company’s management at the levels of executive management and the board of directors, and after the bank applied governance and separated ownership of the institution from management, and competent banking and professional cadres took over the management of that company, which was characterized by efficiency and effectiveness, as the research showed the existence of a close and strong relationship between human capital. Efficiency and financial performance represented by the profitability index, where the level of profits achieved before the change of management was low, while it took an upward trend gradually after the change of management and the application of governance. This confirms the relationship between two variables in achieving what the institution aims to achieve in its current and future strategies.

There is a notable reluctance or uncertainty among practitioners regarding the effective grasp and application of health meditation techniques, which impacts the overall effectiveness of meditation education and potentially hinders the optimization of student learning outcomes in health meditation. This study aims to assess and enhance the effectiveness of teacher education methods in Buddhist Sunday schools, particularly focusing on the impact of these methods on student learning outcomes in health meditation. The research addresses the challenge of reluctance or uncertainty among Buddhist practitioners in grasping and applying health meditation techniques. This study employs a descriptive qualitative approach to provide a comprehensive understanding of the teaching strategies used in health meditation at Vipassana Giri Ratana, Bogor. The methodology encompasses a mix of interviews, observations, and documentation analysis. These methods are chosen to capture a holistic view of the educational practices and the context within which they occur. The primary focus is on the silent education method used by teachers, aiming to explore its effectiveness and impact on student learning. The analytical framework of this research is based on the model proposed, which involves four stages: data collection, data reduction, data display, and conclusion drawing. This framework allows for a systematic and structured analysis of the collected data, ensuring that the findings are robust and credible. Key areas of investigation include the pedagogical content knowledge shared in health meditation, factors influencing the practice of health meditation, and the challenges faced in the implementation of meditation education at Vipassana Giri Ratana, Bogor. The study seeks to provide detailed insights into the nature of health meditation education, including the forms of knowledge imparted and the specific obstacles encountered in practicing meditation education in this context.

The purpose of this article is to identify the factors that influence public compliance with traffic regulations and to find solutions for improving compliance. The data collection techniques used in this research include conducting surveys and field interviews, as well as gathering findings from various sources such as books, journals, and existing studies. As a country governed by the rule of law, Indonesia requires its citizens to abide by the laws in force, which is a fundamental principle in the context of law enforcement. The principle of the rule of law forms the foundation of Indonesia’s legal system, applying to all citizens and institutions, including the government. Compliance with the law is essential for maintaining order and harmony in society. Legal awareness is necessary for the comprehensive enforcement of regulations. Both the public and the government are responsible for understanding and complying with applicable laws, as well as fostering legal awareness in the community and future generations. The research findings reveal that the level of public compliance with traffic regulations in Surakarta is indeed influenced by several social factors such as education, honesty, and law enforcement. Based on these factors, solutions for improving public compliance with traffic regulations include strengthening law enforcement and enhancing the quality of education.
