Abstract

Well water is a primary water source for communities and is vulnerable to contamination by heavy metals, particularly iron (Fe), which, at high concentrations, can cause organoleptic issues such as unpleasant odor, taste, and color, as well as pose health risks. According to Indonesian Ministry of Health Regulation No. 32 of 2017, the maximum allowable Fe content in water is 1 mg/L. This study aims to determine the concentration of Fe in well water samples from Padang City and evaluate the analytical data quality using Atomic Absorption Spectrometry (AAS). Water samples were collected and preserved with HNO₃ to maintain pH < 2, then analyzed using AAS at a wavelength of 248.3 nm. Method performance evaluation showed reliable analytical quality, with a calibration curve coefficient of determination (R²) of 0.9958, indicating excellent linearity. Accuracy validation through spike tests yielded recovery values within the acceptable range (85%–115%). However, the Relative Percent Difference (RPD) of duplicate samples indicated relatively high variability in precision (14.667%–26.415%), suggesting a need for optimization in the sample preparation stage. Despite this, precision in spike quality control showed excellent results, with an RPD of 0.221%. Quantitative analysis showed that all well water samples had Fe concentrations below the instrument detection limit, indicating compliance with water quality standards and general safety for sanitation and hygiene purposes.

Abstract

This study examines the application of artificial intelligence (AI) in developing teachers' soft skills in West Sumatra. AI technology plays an important role in supporting the improvement of communication skills, classroom management, and critical thinking through personalized training and instant feedback. This study uses a qualitative descriptive method with a case study approach to analyze the effectiveness of AI in supporting teacher competency development. The results of the study show that although AI is able to provide positive impacts, the main challenges faced are the digital infrastructure gap and low digital literacy among teachers, especially in remote areas. However, with the support of the right policies and more inclusive training, AI has great potential to improve the quality of education in West Sumatra.

Abstract

This study analyzes the challenges and opportunities for implementing artificial intelligence (AI)-based e-learning in West Sumatra, with global and regional comparisons. Infrastructure gaps are a major obstacle, with 30% of the region lacking adequate internet access, especially in rural areas. In addition, 25% of teachers do not have adequate training in the use of AI technology, hampering the effectiveness of its implementation in schools. Other challenges identified are low digital literacy and limited access to technological devices, which impact 20-25% of schools. This study uses a comparative approach and the results are expected to provide insights and recommendations for policy makers in improving infrastructure, teacher training, and digital literacy, in order to accelerate the adoption of AI in education in West Sumatra.
