Kegiatan ini dilakukan melalui tahapan yaitu penyampaian materi diskusi interaktif, demonstrasi, dan kegiatan praktik. Penyampaian materi dilakukan oleh 3 orang pemateri, kemudian dilanjutkan dengan kegiatan diskusi bersama siswa berkaitan materi yang telah disampaikan. Selanjutnya demonstrasi dilakukan untuk menjelaskan cara mengidentifikasi berbagai jenis spesies dilingkungan sekolah hingga cara menghitung indeks diversitasnya. Kemudian kegiatan praktik dilakukan disekitar lingkungan sekolah. Hasil pengabdian ini yaitu pemahaman siswa tentang keanekaragaman hayati menjadi lebih meningkat, siswa menjadi lebih paham tentang pentingnya menjaga alam sekitar, sehingga dengan kegiatan pelatihan ini siswa menjadi lebih baik dalam merawat lingkungannya.

Abstract

This study is based on the existence of learning activities that are still affected by the Covid-19 virus where learning only relies on material delivered by teachers through learning groups without any interaction that trains collaboration and critical thinking skills of students. This study aims to determine the effect of using the project-based learning model (PjBL) on students' critical thinking skills. The research design uses a pretest-posttest control group design, the research procedure is carried out through preparation, implementation of research, and conclusion. The instruments used are essay questions and instrument sheets with indicators of critical thinking skills. The data analysis technique for the pretest-posttest results uses the t-test (independent sample t-test). The highest critical thinking ability is found in the conclusion-drawing indicator with a value of 86.80. The hypothesis test obtained a t count value of 2.48 and a t table of 1.99, which means that the use of the PjBL learning model has a significant influence on students' critical thinking skills. Based on the results of the hypothesis test, it is known that the project-based learning model (PjBL) has an effect on the critical thinking skills of students at SMA Muhammadiyah 1 Bangurejo.

Abstract

The inquiry learning method in its development has a role in education in schools. In its implementation, the learning method for incuri plays a role for both teachers and students in the learning process, because the incuri method focuses on the activity of students in the learning process, while the teacher as a facilitator and mitivator when the learning process begins.The method used was Quasi Experiment with the Nonequeivalent Contol Group Design. This research was conducted at MT Agung Bandar Agung, East Lampung. In this study consisted of two groups namely the experimental and control groups. Learning outcomes instruments are in the form of a multiple choice form test that has been tested for validity, reliability and distinguishing features and the degree of difficulty. Data analysis using t-test on significance level of 0.05 can be seen from t table> t table.The results of the study revealed that, the learning outcomes of students after using the guided inquiry method was "significant" with an average final test of 84.83. While the learning process without using the guided inquiry method has a "less significant" qualification of 59.16. The t-test for the value of the final test obtained tcount> t table is 10.067> 1.658 at a significant level of 5% or 0.05. This is according to the t-test criteria which means that Ho is rejected and H1 is accepted. From this study it can be concluded that the learning outcomes of students who use guided inquiry methods have a positive effect on learning outcomes in the subject matter of the ecosystem.
