Abstract

This study examines the potential of STEM in the context of indigenous farming systems in Urug Village to improve agricultural sustainability, increase crop yields, and promote environmental conservation through education. Surveys and data collection to identify challenges and opportunities, and to develop solutions that meet the needs of indigenous communities while prioritizing sustainability and environmental conservation are practical steps for this study. Data was collected from the agricultural practices of the Urug indigenous community using the survey method, which included participatory observations, interviews, literature reviews, and documentation. Technical terms are explained upon first mention. The Urug indigenous community follows a series of rice planting procedures. These include babad susukan, seed preparation, seed soaking for two days, stocking, ngabaladah, babad, mingul, ngangler, tandur, ngoyos, ngadares, dibuwat (harvest), lantayan, and ngunjal. The study of science in the community centers around concepts such as astronomy, ecosystems, simple aircraft, pressure, temperature, and heat. Additionally, simple technologies such as terracing, etem, and leuit are employed. Agricultural engineering focuses on environmentally friendly rice farming. Mathematics deals with numbers and operations used in solving numeric problems, as in the calculation of the Pranatamangsa calendar and the Tandur. This agricultural knowledge can be integrated into STEM education.

Abstract

Renewable Energy needs to be implemented in schools to build students' knowledge. This research aims to design a prototype of a Photovoltaic Power Plant (PLTS), which can be used as a medium for experimental high school physics activities. Besides that, the effect of light intensity on the power produced by the PLTS prototype was experimentally tested by observing temperature, humidity, and air pressure. The PLTS prototype is designed to be simple, with component selection (10 wp solar panels, SCC, batteries, lights and panel boxes) that are adapted to the learning media criteria, namely practical, durable, easy to use and able to demonstrate the concepts being taught. The PLTS prototype was tested when charging and discharging the battery. When charging the battery, the solar panel is tilted with a variety of tilt angles of 0º, 15º, 30º, 45º and 60º. When discharging the battery, lamps with varying powers are used, namely 3W, 5W, 7W and 9W. The research results show that the panel tilt angle is used to produce maximum voltage, current, and power when charging the battery, which is 30°. When the battery is discharged, a smaller lamp power can light the lamp for longer compared to a larger lamp power. In conclusion, the PLTS prototype can provide students with experience in conducting experiments and learning the application of physics concepts directly so that it can build students' knowledge and provide meaningful learning.

Abstract

The digital world has inevitably entered various fields of human life in carrying out their duties as world leaders. Technology is an important tool to ease the human workload, including in this discourse is human resource management. This study aims to reveal the perceptions of Taxable Entrepreneurs (PKP) and the Tax Service Office (KPP) on the implementation of e-invoicing and the impact of e-invoicing on taxpayer compliance. The focus of this research is to reveal PKP's perception of the implementation of e-invoicing from the aspects of inputting, data processing, and output. KPP perceptions from the aspects of tax administration and tax evidence, and taxpayer compliance assessed from the aspects of calculation, deposit and reporting. This research is qualitative research with a case study approach. Data analysis is carried out interactively starting from data collection, data reduction, data presentation, and conclusion drawing. According to PKP, the advantages of e-invoicing are more efficient processing time, more accurate tax calculation results, easier and safer storage because it has a QR code, but the weaknesses of e-invoicing are repetitive work in inputting input tax values, the system is not yet able to read invoice codes and the application is vulnerable to viruses. According to KPP, the application of e-invoicing is very helpful for the tax office in fully controlling in real time all tax invoices uploaded and reported by PKP. From the research results, there is not enough evidence that e-invoicing has an impact on improving taxpayer compliance, especially in tax calculations. According to the Tax Office, the application of e-invoicing can improve taxpayer administrative compliance in terms of calculating, depositing and reporting so that tax revenue will be increased.

Abstract

:  Computer technology with digital power will bring better tax payment procedures and expectations of compliance levels. The digital world will encourage increasingly widespread use of artificial intelligence components to make tax-related work easier. This research falls under comparative causal studies using a survey method. The population consists of MSME operators (individual taxpayers) in the city of Binjai who have filled out and returned the questionnaire to the researchers. The sample selection was carried out using purposive sampling technique, and data was gathered from the opinions or perceptions of MSME operators (individual taxpayers) in Binjai. The primary data obtained were descriptively analyzed, and the model and the influence of tax rates and tax penalties on taxpayer compliance through tax understanding were examined using path analysis. The findings indicate a significant influence of tax rates and tax penalties on taxpayer compliance both simultaneously and partially, with tax understanding as an intervening variable not fully proving to mediate the relationship between tax rates and penalties on taxpayer compliance. The low path analysis value in this study should be considered by subsequent researchers to include other variables that may affect corporate value
