Abstract

Critical thinking ability is one of the important competencies that students must possess in biology learning. This research aims to develop Problem-Based Learning (PBL) Student Worksheets to train students' critical thinking skills in Plant Anatomy courses. This research uses the Research and Development method with a simplified 4-D model consisting of three stages: Define, Design, and Develop. The research subjects were second-semester Biology Education Study Program students at Universitas Muhammadiyah Bengkulu. Research instruments included media and material expert validation sheets, as well as student response questionnaires. Validation was conducted by one media expert and one material expert, then tested on 5 students (limited trial) and 22 students (extensive trial). Validation results showed that the student worksheets received a "very valid" category with 86% from media experts and 88% from material experts. Practicality tests showed "very practical" results with 89% in limited trials and 91% in extensive trials. The developed student worksheets contained contextual problem scenarios, systematic PBL stages, and critical discussion questions that encourage students to analyze, evaluate, and conclude based on empirical data. This research concludes that PBL-based student worksheets are feasible to use as learning media to train students' critical thinking skills in Plant Anatomy courses.

Abstract

This study aims to analyze the influence of interest rates, exchange rates, and coffee production on the value of coffee exports in South Sulawesi. The background of this study is based on the condition of South Sulawesi coffee exports which have experienced significant fluctuations in recent years despite coffee production tending to increase. This study uses a quantitative approach with time series data for the period 2009-2023 sourced from the World Bank, International Monetary Fund and the Directorate General of Plantations, the Food Crops, Horticulture and Plantation Service of South Sulawesi Province. Data analysis was conducted using multiple linear regression through the EViews 12 application with the classical assumption test as a model prerequisite. The results show that partially interest rates have a significant effect on coffee exports, while exchange rates and coffee production do not have a significant effect. Simultaneously, the three independent variables do not have a significant effect on the value of coffee exports. This finding indicates that external factors, especially interest rates, are more dominant in determining the performance of South Sulawesi coffee exports than internal factors of production and exchange rates.

Abstract

This study investigates the factors influencing export performance in five ASEAN countries Indonesia, Malaysia, the Philippines, Singapore, and Thailand during the 2014-2023 period. The topic is highly relevant given the vital role of exports in sustaining monetary stability and promoting long-term economic growth. The novelty of this research lies in its integrated approach, which simultaneously examines key export-related macroeconomic variables, namely foreign direct investment and inflation, while incorporating foreign exchange reserves as a moderating variable an approach that remains limited in existing ASEAN-focused studies. This analysis uses secondary data obtained from the World Bank and processed using panel data regression methods, including the Common Effect Model, Fixed Effect Model, and Random Effect Model, strengthened by a Moderated Regression Analysis (MRA) approach. The results show that foreign direct investment and inflation significantly influence foreign exchange reserves. Furthermore, foreign exchange reserves have been shown to play a strategic role in strengthening the economic resilience of ASEAN countries and can be used as a reference in formulating monetary and international trade policies.
