Abstract

Conventional water filters available in the market cannot measure water quality, detect filter condition, automatically backwash when the filter is dirty and cannot be monitored anywhere. Therefore, by using ESP32, the filter condition can be determined and backwash if needed. From the existing problems, it is necessary to implement a control system and monitor the condition of the water filter, with the program features on the microcontroller and the web display used to control and monitor the tool, as well as internet of things-based testing and measurement of the tools made. From the research conducted, all sensors work well and the web display displays data in realtime so that it can support the performance of the tool to work as desired both automatically and manually.

Abstract

The study aims to design and develop a freeware application for electrical installation planning analysis. This research is categorized as development research, adopting the RAPID Application Development (RAD) model. The data collection process in this study involved a series of methods, including direct observation of the learning process, in-depth interviews with potential users, and the distribution of structured questionnaires to relevant respondents. The analysis of the collected data was carried out using a quantitative descriptive method, which aimed to describe and interpret numerical data related to the performance and acceptance of the developed application. The overall results of this study indicate that the designed and developed freeware application, as a learning media for electrical installation planning analysis, demonstrates highly satisfactory performance and falls into the "Very Good " category. Specifically, the evaluation of the application's functionality aspect showed a success rate of 100%, indicating that all designed features and functions operate according to the expected specifications. Similarly, the assessment of the user interface aspect also reached a percentage of 100%, implying that the application's interface design is intuitive, easy to use, and overall provides a positive user experience. In addition, in terms of material and media feasibility, it produces "Highly Feasible". The application is determined to effectively incorporate electrical installation planning content pertaining to the learning outcomes of determining cable sizes and circuit breaker capacity. Consequently, this freeware application has significant potential to become an effective learning media in enhancing the understanding and skills of students and practitioners in the field of electrical installation planning.

Abstract

This development research aimed to develop, assess the feasibility, determine student responses, and evaluate the effectiveness of virtual reality-based electrical motor rewinding learning media in enhancing electrical equipment repair competency at Vocational High Schools. Using the ADDIE model (Analyze, Design, Develop, Implement, Evaluate), the study was conducted at State Vocational High Schools 5 Batam, State Vocational High Schools 7 Batam, and S State Vocational High Schools Teladan Batam. The subjects were 11th-grade students specializing in Electrical Power Installation. Data was collected via interviews, questionnaires, and tests. Expert judgment validated the instruments, and Cronbach Alpha confirmed their reliability. Data analysis involved descriptive statistics and t-tests. The study yielded Virtual Reality based electrical motor re-winding learning media, a guidebook, and job sheets. Feasibility tests showed "very feasible" ratings from both material experts (93%) and media experts (83%). Student responses in the experimental group were "very good" (87%). The media proved effective in improving competency, with experimental group post-test scores significantly higher than the control group. The media demonstrated a "moderate" effectiveness level with a gain score of 0.47, and a t-test value of 0.000 indicated that Ho was rejected and Ha accepted, confirming its effectiveness in enhancing electrical equipment repair competency.

Abstract

This study aims to determine the effect of tax planning and voluntary disclosure on firm value with earnings quality and audit quality as moderation in pharmaceutical industry manufacturing companies listed on the Indonesia Stock Exchange for the period 2009-2018. The sample in this study amounted to 80 samples determined by the purposive sampling method. Tests are carried out using the Moderated Regression Analysis (MRA) test using Eviews 9. The test results show that tax planning and earnings quality have a significant negative effect on firm value. Voluntary disclosure has a positive effect on company value. And the quality of earnings does not affect the value of the company. Tax planning and voluntary disclosure have a significant effect on company value when moderated by earnings quality. Tax planning and voluntary disclosure do not have a significant effect on company value when moderated by audit quality. Earnings quality and audit quality can strengthen the relationship between tax planning and voluntary disclosure of company value.

Abstract

This research investigates the various factors that affect entrepreneurial interest among vocational secondary school students enrolled in the electronics engineering program in Yogyakarta, Indonesia. The study identifies entrepreneurship as a crucial mechanism for fostering innovation, self-employment, and enhancing national competitiveness. It examines five primary determinants: self-efficacy, family support, entrepreneurial attitude, entrepreneurship education, and social and institutional support. A quantitative ex post facto methodology was utilized, involving 104 respondents chosen through proportional random sampling from three vocational institutions.  Data collection employed a validated four-point Likert scale questionnaire, with analysis conducted via simple and multiple linear regression techniques utilizing SPSS. The findings indicate that all five variables have significant and positive impacts on students' entrepreneurial interest, both independently and in combination. Entrepreneurship education and social–institutional support exhibit the most significant impact, underscoring the critical role of practical learning, mentorship, and supportive ecosystems in shaping entrepreneurial trajectories.  Self-efficacy and family support enhance motivation and confidence, while positive entrepreneurial attitudes promote perseverance and proactive engagement in opportunity recognition. These factors account for nearly half of the variance in entrepreneurial interest, thereby affirming the significance of the Theory of Planned Behavior and Social Cognitive Theory within vocational contexts. This study empirically enhances the discourse on entrepreneurship in technical and vocational education by highlighting the combined influence of psychological, familial, educational, and structural supports on the development of entrepreneurial intentions. Policy implications indicate that promoting entrepreneurship necessitates the alignment of curricular design, family involvement, and institutional policies to enhance entrepreneurial ecosystems within vocational education. Vocational schools can enhance student empowerment by fostering self-efficacy and offering accessible institutional resources, enabling the translation of entrepreneurial aspirations into sustainable ventures.

Abstract

Tax is a mandatory contribution that taxpayers must submit to the state in accordance with the provisions of the law. However, in reality, tax avoidance by multinational companies through profit shifting has resulted in Indonesia losing tax revenue every year. Based on this, the discussion in this study is the causes of the threat of tax avoidance by multinational companies through profit shifting. This research also discusses intelligence strategies in facing the threat of tax avoidance. The method used is qualitative with data sourced from interviews and literature studies. The analysis used is Creswell analysis processed through the Nvivo application. This research also uses data source triangulation to examine data validity. Based on the research results, the causes of this threat are the intention and ability to jeopardize tax revenue. Intelligence strategies in facing this threat are a combination of intelligence objectives, intelligence methods, and intelligence resources. Intelligence objectives include state revenue, tax compliance, and Data-Based Organizations. Intelligence methods include Business Intelligence (BI), Compliance Risk Management (CRM), and data analysis. Intelligence resources include cooperation and data and information.
