Abstract

The increasing demand for 21st-century education requires innovative learning models that enhance students’ critical thinking and problem-solving skills. This study aims to analyse the effect of the Problem-Based Learning (PBL) model on Biology learning outcomes among Grade XI students at SMAN 1 Sikur, East Lombok. A quantitative approach was employed using a quasiexperimental design with a pretest–posttest control group. The sample consisted of two classes, XI IPA 1 (control group) and XI IPA 3 (experimental group), each comprising 30 students. Data were collected through pretests and post-tests and analysed using an independent samples t-test. The results showed a significant difference in post-test scores between the experimental group (81.2) and the control group (73.3), with a p-value of 0.0006 (p < 0.05). It can be concluded that the PBL model has a significant positive impact on students’ biology learning outcomes. These findings imply that PBL can be a practical instructional approach to foster meaningful and skilloriented learning in secondary education.

Abstract

Mangrove ecosystems provide essential ecological and socio-economic services that support coastal sustainability, yet their potential has not been fully optimized in ecotourism development. This study aims to identify the roles of mangrove ecosystem services, review effective ecotourism models, and formulate development recommendations for the Tanjung Batu Mangrove Area. A Systematic Literature Review (SLR) following the PRISMA 2020 protocol was conducted, and 52 eligible articles were analyzed using thematic synthesis supported by bibliometric mapping. The findings show that regulating and cultural ecosystem services are the most influential in shaping mangrove ecotourism, particularly through shoreline protection, habitat support, and educational value. Community-based ecotourism (CBE), educational tourism, and conservation-oriented approaches emerge as the most effective models across tropical coastal regions. Successful implementation is determined by ecological integrity, community participation, and supportive governance. For Tanjung Batu, integrating these components offers a strategic framework for enhancing tourism potential while strengthening conservation outcomes. This study recommends applying a hybrid community-based and education-focused ecotourism model supported by governance collaboration to ensure long-term ecological resilience and sustainable coastal development.
