Students\u27 Mathematical Modeling Ability in Answering 2022 PISA-released items in Scientific Context
Get PDFMathematical modeling is one of the essential 21st-century skills that students must possess to connect mathematical concepts with real-world problems. Despite its recognized importance, the performance of Indonesian students in modeling tasks remains low, as reflected in the 2022 PISA results. This study aims to analyze students\u27 mathematical modeling ability in solving scientific-context problems derived from the 2022 PISA-released items. The research used a descriptive qualitative method involving 25 seventh-grade students from SMP IT Raudhatul Ulum. Data were collected through students\u27 written responses to four PISA problems and analyzed using a rubric based on modeling indicators by Blum and Leiss. The findings show that most students—56%—are in the low category of modeling ability, 36% are in the medium category, and only 8% reach the high category. Students struggle to translate real-world problems into mathematical models and interpret results contextually. These findings highlight the need for contextual learning strategies to strengthen students\u27 modeling competencies in scientific settings

Growth and Content of Flavonoids of Mustard Greens (Brassica juncea L.) with Different Humic Acid and Water Content
Get PDFWater deficiency disrupts metabolic pathways and reduces plant growth. The high demand for Brassica juncea (L.) due to its nutritional value necessitates improved cultivation practices to ensure high-quality yields. Although humic acid is known to support plant productivity, studies examining its interaction with soil moisture levels in B. juncea remain limited. This study aimed to determine the optimal soil moisture level and humic acid dosage for enhancing the growth and flavonoid content of B. juncea (L.). The experiment was conducted using a Randomized Block Design (RBD) with two factors: four levels of humic acid dosage (0 g/kg, 4 g/kg, 8 g/kg, and 12 g/kg) and four watering treatments based on field capacity (FC), namely 20%, 40%, 60%, and 80%, each with four replications. Observations were made 42 days after planting, covering plant height, number of leaves, leaf area, dry weight, and total flavonoid content. Data were analyzed using ANOVA at a 95% confidence level, and significant differences among treatments were further tested using Duncan’s Multiple Range Test (DMRT). The results showed that the treatment combination of 20% FC and 12 g/kg humic acid produced the highest values for growth and flavonoid content of B. juncea L. under drought stress conditions, with plant height (23.67 cm), number of leaves (8 leaves), leaf area (1,022 cm²), dry weight (0.55 g), and total flavonoid content (0.108 mg QE/g sample).Water deficiency disrupts metabolic pathways and reduces plant growth.

Implementation Analysis of Enterprise Risk Management (ERM) and Risk Mitigation Strategies in Securities Companies in the Digital Era
No full textThis study aims to analyze the effectiveness of implementing Enterprise Risk Management (ERM) and operational risk mitigation strategies in securities companies in the digital era. Amid the high dependence on technology, disruptions to trading systems have become a serious threat to business stability. The research method uses a descriptive qualitative approach with primary data obtained through interviews and observations, as well as secondary data in the form of financial reports and capital market statistics. Risk analysis is carried out using a likelihood–impact matrix based on Financial Services Authority regulations. The results show that operational risks in the form of technical disruptions (glitches) in online trading applications and reputation risk occupy the highest risk level (high risk). System reliability, including the Sharia Online Trading System (SOTS), is proven to be a fundamental factor in maintaining investor confidence. In addition, disciplined risk management implementation contributes positively to net profit growth and long-term business sustainability. The study concludes that mitigation priorities must be focused on strengthening information technology infrastructure and enforcing credit risk control procedures in order to minimize financial losses.This study aims to analyze the effectiveness of implementing Enterprise Risk Management (ERM) and operational risk mitigation strategies in securities companies in the digital era.
