Abstract

This study aims to develop an ethnoscience-based science teaching module on the forms of matter and their changes to improve elementary school students’ scientific literacy, as well as to determine its characteristics, feasibility, effectiveness, and practicality. The research employed a Research and Development (R&D) design using the 4D model proposed by Thiagarajan, Semmel, and Semmel, consisting of the Define, Design, Develop, and Disseminate stages. The module integrates local cultural knowledge from Bangka—such as traditional foods including martabak, jongkong cake, and es jeruk kunci—to contextualize scientific concepts for young learners. The results show that the developed module meets high validity standards, with Aiken’s V values of 0.88 for material experts, 0.86 for language experts, and 0.85 for media experts, all categorized as “very valid.” Effectiveness testing revealed an N-gain score of 0.80 (80%), indicating an effective improvement in students’ scientific literacy. Practicality assessments also demonstrated excellent results, with teacher responses averaging 95.31% and student responses 97.50%, both categorized as “very practical.” These findings indicate that the ethnoscience-based teaching module is valid, effective, and practical for enhancing scientific literacy in elementary school science learning.

Abstract

Taxpayer compliance remains a critical challenge in Indonesia’s tax revenue optimization, despite ongoing reforms in administration and enforcement. Corporate taxpayers often face complexities in the self-assessment system, leading to reliance on professional tax consultants. However, the interplay between consultant service quality, the tax administration system, and the role of sanctions in shaping compliance behavior has not been comprehensively examined, particularly in regional contexts. This research aims to analyze the influence of tax consultant service quality and the tax administration system on taxpayer compliance, with tax sanctions as a moderating variable. The research employs a quantitative approach using primary data collected from 106 corporate taxpayers registered at the Samsiah Tax Consultant Office in Cirebon, West Java, selected through saturation sampling. Data were analyzed using descriptive statistics, classical assumption tests, multiple linear regression, and Moderated Regression Analysis (MRA) via SPSS. The findings reveal that tax consultant service quality, the tax administration system, and tax sanctions each have a positive and significant direct effect on taxpayer compliance. Improvements in administrative systems and consultant professionalism significantly reduce the compliance burden and enhance adherence to tax regulations. However, the moderation test indicates that tax sanctions do not moderate the relationship between service quality or the administration system and taxpayer compliance. This study concludes that while tax sanctions function effectively as an independent deterrent, enhancing the quality of consultant services and the efficiency of the tax administration system should be prioritized as primary strategies for improving taxpayer compliance. The findings provide theoretical contributions to the attribution and deterrence frameworks and offer practical implications for tax authorities and consultants in designing targeted compliance interventions.
