Abstract

The complexity of science concepts which are interrelated with each other requires the competence to think systematically. Complex thinking which is the basis for critical, analytical, creative and metacognitive thinking is very important to master in responding to the challenges of the 21st century. The aim of this research is to explore students' thinking systems taught using the STEM-PjBL model. This research is quantitative descriptive research. The variables studied are students' thinking systems based on the ability to determine components that influence each other in the bioethanol synthesis and dehydrator processes. The population in the study was 17 students. Students are distributed in two semesters, namely semesters II and IV. The research uses pre-test and post-test systematic thinking ability tests as data collection techniques and tools. The test consists of 5 essay questions that assess students' systematic thinking competence, and the test used is analyzed for validity, discrimination power, and level of difficulty before use. This test was developed based on indicators of systematic thinking competency. Tests were given to students before and after carrying out project activities for making and dehydrating bioethanol. After carrying out the project, students strengthen their competence through computational simulations related to the project being carried out. The data obtained is then presented in a communicative graph. The research results showed that 35.2% had high system thinking, 29% medium, 35.6% low. These results show that the application of the STEM-PjBL model is able to foster students' systematic thinking competency.

Abstract

The Bayan traditional house in Lombok, West Nusa Tenggara, exemplifies traditional architecture that integrates Indigenous Knowledge (IK) in building construction. This study aims to analyze the construction techniques of the Bayan traditional house in enhancing earthquake resistance and environmental adaptation while exploring its potential application in sustainable modern architecture. A qualitative research approach with a case study design was employed, incorporating participant observation, in-depth interviews with key informants, and document and visual analysis. Findings reveal that Bayan traditional houses utilize distinctive construction techniques such as nail-free wooden joinery, flexible local materials like bamboo and hardwood, and thatched roofs that adapt to tropical climates. These techniques enhance structural flexibility in absorbing seismic shocks while providing optimal thermal efficiency and natural ventilation. These findings align with previous studies indicating that IK-based structures demonstrate greater resilience compared to modern concrete buildings. This study asserts that IK principles in Bayan traditional houses can be integrated into contemporary architectural design to create more environmentally friendly and disaster-resilient buildings. Therefore, policies promoting the adoption of IK-based construction techniques in modern housing and infrastructure development are essential to enhance sustainability and disaster preparedness in the future.
