In this study, the solubility of m-hydroxybenzoic acid in 14 organic pure solvents (acetone, iso-propanol, ethanol, n-propanol, methanol, ethylene glycol, n-pentanol, n-butanol, methyl acetate, n-propyl acetate, ethyl acetate, butyl acetate, iso-propyl acetate, acetonitrile) at the pressure of 0.1 MPa (at T = 278.15–323.15 K) was studied by the static weight method. The order of solubility (molar fraction) of m-hydroxybenzoic acid in the 14 pure solvents at 278.15 K was acetone > iso-propanol > ethanol > n-propanol > methanol > ethylene glycol > n-pentanol > n-butanol > methyl acetate > n-propyl acetate > ethyl acetate > butyl acetate > iso-propyl acetate > acetonitrile. As the temperature improved, the solubility correspondingly increased. The m-hydroxybenzoic acid solubility data in pure solvents were connected using the modified Apelblat model, the λh model, the NRTL model, and the Wilson model, and the best-fit performance was obtained using a modified Apelblat model. Performance was obtained using a modified Apelblat model. Two molecular dynamics analysis methods, Hirshfeld surface analysis and molecular electrostatic potential surface (MEP) analysis, were used to determine the dissolution process of m-hydroxybenzoic acid crystals and the interaction sites with solvent molecules in solution. The Hansen solubility parameters (HSPs) were utilized to assess the solvent’s capability and to elucidate its ability to dissolve m-hydroxybenzoic acid.

This research investigates the strategies for utilizing artificial intelligence (AI) and data analytics to enhance the effectiveness of public services within Indonesian local governments. A quantitative analysis was conducted, involving a diverse sample of 200 participants, including local government officials, IT professionals, and citizens across various regions. The study employs a structural equation modeling approach, assessing the relationships between the implementation of AI, data analytics, and the effectiveness of public services. The measurement model confirms the reliability and validity of the constructs, while the structural model reveals significant positive paths from both data analytics and AI utilization to public service effectiveness. The findings contribute to the evolving landscape of technological integration in public administration, offering evidence-based insights for policymakers and practitioners.
