Abstract

The Central Laboratory of Universitas Andalas is equipped with Shimadzu 9050 Quadrupole Time-of-Flight (QTOF) LC-MS/MS instrument, which has strong potential to support scientific research at international standards. However, the utilization of this instrument remains limited due to the lack of optimized standard methods for both qualitative and quantitative analyses. This study aims to develop an LC-MS/MS analytical method that can be used as a standard method for research services in the laboratory. The research stages included sample preparation of red flower (BM) and white flower (BP) by extraction of sample using methanol pH 3 as the solvent, separation of sample using a rotary evaporator, method optimization including selection of mobile phase composition (isocratic and binary gradient), selection of analysis time (5, 10, and 15 minutes), and optimization of collision energy in the range of 5–40. Quantitative analysis of flower samples was then conducted using the optimized method. The optimisation results showed that a binary gradient mobile-phase method with an analysis time of 15 minutes and a collision energy of 25 could be used as the analytical method. Furthermore, quantitative analysis of both flower samples revealed that cyanidin in the red flower sample was 24.92 ppm, while cyanidin in the white flower sample was 71.69 ppm.

Abstract

Purpose – This study examines the extent to which the Grade V Arabic textbook issued by the Kementerian Agama Republik Indonesia supports writing instruction in accordance with the pedagogical principles of Douglas Brown. Design/methods/approach – The research used a qualitative content-analysis method to scrutinize maharah al-kitābah items in the Grade V textbook intended for Madrasah Ibtidaiyah students and to map task types against a theoretical coding framework. Findings – Analysis identified predominant task formats—picture-based word and phrase writing, simple sentence assembly, and constrained dialogue completion—that systematically reinforce vocabulary and orthographic accuracy. Evidence of Brown’s principles (e.g., meaningful learning, affective support, and strategic investment) appears in the textbook’s design, yet explicit process-writing sequences (prewriting, drafting, revising, publishing) and opportunities for extended, genre-varied composition are largely absent. Research Implications – These patterns suggest that the textbook affords essential foundational skills but insufficiently scaffolds fluency, idea development, and iterative revision for young L2 writers. The study recommends integrating concise, age-appropriate process-writing modules, teacher-facing scaffolds, and pilot classroom trials paired with professional development to evaluate impacts on composition outcomes. Limitations include single-textbook scope and analysis limited to printed materials rather than classroom enactment, which future mixed-methods research should address.
