Abstract

This research was conducted due to the low problem-solving skills and learning outcomes of students at SMA Negeri 13 Bone due to unattractive conventional learning methods and the minimal use of interactive learning media. This study aimed to determine the effect of implementing the Problem-Based Learning model supported by SPICO (Spinner Game Economy) learning media on student learning outcomes at SMA Negeri 13 Bone. This study was a pre-experimental study with a One Group Pre-Test and Post-Test design. A sample of 35 students was selected using a random sampling technique. Data were collected through learning achievement tests and documentation, then analyzed using descriptive and inferential statistics, including normality tests, homogeneity tests, and paired sample tests. The results showed a significant increase, from an average pre-test score of 39.86 to a post-test score of 85.43, with the majority of students in the high to very high categories. These findings indicate that the implementation of PBL supported by SPICO media has an impact on student learning outcomes at SMA Negeri 13 Bone and encourages students to be more active, critical, and confident in their learning.

Abstract

Abiotic stress is an environmental condition that is unfavorable for plants such as drought, salinity, heavy metal contamination and nutrient deficiencies. Prolonged abiotic stress causes the stability of plant cell organelles to be disrupted, thereby inhibiting plant growth and development. This research aims to examine the role of membrane transport in responding to environmental stress, especially abiotic stress, and the implications for plant growth and development. The research method used was a literature study using meta-analysis techniques assisted by prism diagrams in analyzing 14 relevant scientific articles from various national and international journals. The analysis was carried out descriptively on the results of previous research. The results show membrane transport has a role in increasing plant resistance to abiotic stress. Cell membrane structure consisting of lipids, proteins and carbohydrates has been proven to increase plant safety from environmental stress. So it can be concluded that membrane transport has a role in mediating tolerance, resistance, and resolving plant stress conditions through maintaining cellular homeostasis. Implications of this research can help expand knowledge about how plants respond to unfavorable environmental conditions through membrane transport mechanisms and can be basis for developing plant varieties are resistant to various forms of environmental abiotic stress.
