Abstract

This study aims to evaluate the implementation of evaluation and assessment in mathematics learning at MAN 1 Padang, focusing on the gap between the ideal expectations and the reality in the classroom. Using a descriptive qualitative approach and semi-structured interviews with mathematics teachers of grades 10, 11, and 12 conducted in May 2025, this study analyzes the evaluation practices, challenges encountered, and the alignment between expectations and actual practice. The results indicate that mathematics evaluation is still dominated by written tests that inadequately measure students' comprehensive abilities, while time constraints, conventional teaching methods, and low student participation remain significant obstacles. Therefore, it is necessary to develop more varied and authentic evaluation instruments and enhance teachers' capacity through training to make assessments more effective in supporting the achievement of comprehensive and sustainable mathematics learning objectives.

Abstract

Linear programming is one of several methods for finding combinations of numbers to maximize or minimize the objective function in order to produce an optimal solution. However, manual calculations take a long time due to the complexity of the Linear Programming formula. In this paper, the author designs an application to solve web-based Two-Phase Simplex Linear Programming problems using the Angular JavaScript Framework. The application can solve Linear Program problems accurately after the mathematical model is entered. Because the method used is the Simplex Method, the application is also able to solve problems that have more than 3 decision variables. The results obtained are a combination of numbers in the decision variables along with their optimal solutions.

Abstract

Palm wine (tuak) is a traditional fermented beverage that is prone to microbial contamination, thus requiring natural alternatives with antibacterial properties. This study aimed to determine the effectiveness of Curcuma xanthorrhiza (temulawak) extract in inhibiting microbial growth in tuak samples. The method used was the disc diffusion test with three extract concentrations, 25%, 50%, and 100%. The tuak samples were first femented, serially diluted, and inoculated on Nutrient Agar (NA). Sterile paper discs soaked in each extract were placed on the medium surface and incubated at room temperature for 24 hours. The results showed no visible inhibition zones around the discs at any concentration tested. The conclusion of this study is that temulawak extract at concentrations of 25–100% did not demonstrate antibacterial activity against microorganisms in tuak samples. This study serves as a foundational evaluation of natural antibacterial agents and highlights the need for further optimization of extraction techniques or targeted testing on specific bacterial isolates.

Abstract

Orthosiphon aristatus is a medicinal plant that has the potential as a natural antibacterial agent. This study aims to evaluate the effect of cat's whiskers leaf extract on microbial growth using Nutrient Agar (NA) media with variations in extract concentrations of 100 gr, 50 gr, and 25 gr. Antibacterial activity tests were carried out using the well diffusion paper disk method, and observations of microbial growth inhibition zones were carried out after incubation for 24 hours at 37°C. The test results showed that there was inhibition of microbial growth that varied according to the concentration of the extract used; a concentration of 100 gr gave the largest inhibition zone compared to 50 gr and 25 gr. Data analysis showed that increasing extract concentration was directly proportional to increasing antibacterial effectiveness. These findings indicate that Orthosiphon aristatus leaf extract has the potential as a natural antibacterial that is effective in inhibiting microbial growth in NA media, so it has the potential to be developed as an active ingredient in pharmaceutical formulations.
