Abstract

The primary focus of physics instruction in schools is to improve students' problem-solving skills. This study aims to determine whether employing problem-based learning can enhance students' problem-solving skills. This study employs a quasi-experimental design with a non-equivalent control group. It was discovered that students' problem-solving skills remained deficient due to less collaborative and active learning. The study was carried out in classes XI A through XI D at MAN 1 Mataram. The researchers used purposive sampling, which resulted in XI C and XI D being designated as the experimental and control classes, respectively. The test used in the research data collection method consisted of ten questions. Pretest and posttest results are research data. NGain is used to evaluate the effectiveness of the learning process. According to the N-Gain results, the N-Gain of the experimental class was 0,66, whereas the control class was 0,48. Therefore, it can be said that using PhET simulations to facilitate problem-based learning is a good way to enhance problem-solving abilities. Compared to traditional learning, the use of the problem-based learning paradigm with PhET simulation is more successful.

Abstract

Seagrass ecosystems play a crucial bioecological role in maintaining coastal stability, yet their management at the local level continues to face significant challenges. This study aims to analyze the conditions, threats, and bioecological aspects that underpin sustainable seagrass management in Sekotong. A case study approach was employed, using semi-structured interviews with purposive sampling, with the West Lombok Marine and Fisheries Office (DKP) as the key informant. The literature review was selected based on criteria focusing on seagrass bioecology, ecosystem threats, and coastal management. Data were analyzed through reduction, categorization, and synthesis. The results show that while some areas retain stable seagrass cover (supported by mangrove/coral rehabilitation), other areas are vulnerable to degradation from marine tourism, increased sedimentation, and declining water quality. Bioecologically, species such as Enhalus acoroides, Thalassia hemprichii, and Cymodocea rotundata function as habitat providers, blue-carbon storage, and substrate stabilizers, but their resilience is heavily influenced by ecological pressures. The study concludes that effective seagrass management requires integrating bioecological data, regulating marine tourism, and enhancing coordination between the Regency and Provincial DKP. This research underscores the need for an integrated monitoring system and further provincial-level research to strengthen future conservation policymaking.
