The teaching and learning process is built on three interaction aspects such as the interaction among the teachers, students, and learning sources. To ease this process, the teacher can make their own teaching material that will be used in learning process. This research aims to develop weather theme students’ book by using Four Steps Teaching Material Development (4STMD) method. The research method used was Research and Development (R&D). This students’ book consists of 5 sub-themes such as substance characteristics, interaction of organisms and their environment, temperature and heat, pollution and global warming. This book was developed by using 4STMD method through four stages such as selection, structurization, characterization, and didactic reduction. The feasibility test results show that the student book has complete material based on basic competencies and indicators, has accurate, actual and integrated material. Besides the student’s book that was developed also has aspects of legibility, language rules and language logic that is appropriate, presented attractively and has a layout and design that is feasible to be used. Overall the students’ perception on the usage and result of this students’ book development is positive. ABSTRAKProses belajar mengajar dibangun oleh tiga aspek interaksi. Interaksi tersebut adalah interaksi antara pendidik, peserta didik dan sumber belajar. Untuk memudahkan proses tersebut, guru dapat membuat sendiri bahan ajar (buku) yang akan digunakan dalam proses belajar mengajar. Penelitian ini bertujuan untuk mengembangkan buku siswa bertema Cuaca  dengan metode Four Steps Teaching Material Development (4STMD) dan menganalisis kelayakan serta persepsi siswa terhadap buku siswa yang dihasilkan. Metode penelitian yang digunakan adalah Research and Development (R&D). Buku siswa ini terbagi atas 5 sub tema yaitu karakteristik zat, interaksi makhluk hidup dengan lingkungannya, suhu dan kalor, pencemaran dan pemanasan global. Buku ini dikembangkan dengan metode 4STMD melalui empat tahap, yaitu seleksi, strukturisasi, karakterisasi dan reduksi didaktik. Hasil Uji Kelayakan menggambarkan bahwa buku siswa memiliki cakupan materi yang lengkap berdasarkan Kompetensi Dasar dan indikator, memiliki materi akurat, mutakhir serta terpadu. Selain itu buku dikembangkan juga memiliki aspek keterbacaan, kaidah bahasa dan logika bahasa yang baik, disajikan dengan menarik dan memiliki tata letak serta desain yang layak digunakan. Adapun persepsi siswa terhadap penggunaan dan hasil pengembangan buku siswa, secara keseluruhan bernilai positif.

Kompetisi Sains Nasional (KSN) memberikan peluang bagi siswa untuk berkompetisi dalam bidang ilmu pengetahuan dan teknologi. Kegiatan ini merupakan agenda tahunan yang diselenggarakan oleh Direktorat Jenderal Pendidikan Dasar dan Menengah Kementerian Pendidikan dan Kebudaya­an. Kegiatan Program pendampingan ini bertujuan untuk mem­berikan pemantapan dan pendalaman materi biologi SMA, yang meliputi: (1) Biologi Sel Molekuler, Mikrobiologi, dan Bioteknologi, (2) Anatomi dan Fisiologi Tumbuhan, (3) Anatomi dan Fisiologi Hewan, (4) Genetika dan Evolusi, (5) Etologi, (6) Ekologi, dan (7) Biosistematik pada program pembina­an olimpiade Biologi bagi siswa terseleksi tingkat kota/kabupaten. Metode yang digunakan adalah menerapkan strategi kontekstual, melalui metode praktik terbimbing dengan pemecahan masalah yang dihadapi siswa peserta olimpiade mengenai pemahaman dan kedalaman materi KSN bidang biologi. Pelaksanaan kegiatan pelatihan ini bertempat di labora­torium pembelajaran FKIP Unila dan Aula Perpustakaan SMAN 5 Bandar Lampung yang dilaksanakan pada bulan Januari sampai dengan April 2020. Peserta kegiatan adalah siswa SMA yang telah terseleksi kegiatan KSN Biologi tingkat sekolah yang berjumlah 11 orang peserta. Hasil kegiatan pen­damping­an menunjukkan adanya peningkatan penerapan iptek bagi siswa yang terukur sebagai output melalui lolosnya peserta pada tingkat 4 dan 10 besar  tahapan KSN Tingkat Provinsi Lampung. Hal ini membawa dampak pe­ning­katan signifikan terhadap pemahaman siswa di SMAN 5 Bandar Lampung, yang sebelumnya belum pernah lolos kegiatan KSN Bidang Biologi pada tingkat Provinsi.

This study aimed to describe the diversity of plants found in Bukit Barisan Selatan National Park. The analysis of plant diversity was carried out by applying the quadratic method. Twenty-five squares were constructed for sampling. The results showed that there were thirty two (32) plant tribes consisting of 256 individuals in the exposed area and 899 individuals in the burial area. Data on plant diversity were then mapped to be correlated with Basic Competence (BC) at each level of the educational unit. Mapping results showed, there are 6 BC at the elementary school level; 5 BC at the junior high school level; and 7 basic competencies at high school level that can be learned by utilizing information on plant diversity of Bukit Barisan Selatan National Park. Based on the results of the analysis, it is known that the existence of plant diversity in Bukit Barisan Selatan National Park has the potential to support the achievement of the objectives of the national curriculum.

This study aimed to describe students' metacognitive awareness and higher-order thinking skills through environmental issues-discovery. The research design was quasi-experimental with a pretest-posttest design. The data were collected through 52 Metacognitive Awareness Inventory (MAI) statements and the critical thinking test. The results show that the levels of students' metacognitive awareness are undeveloped (18 Percent), at-risk (8 Percent), poor (15 Percent), developed (22 Percent), high (14 Percent), and excellent (23 Percent). The discovery learning model significantly affects students' higher-order thinking skills (significant value of 0.000 with a 0.05 confidence level). Therefore, teachers are advised to utilize the surrounding environment in the discovery learning model to improve higher-order thinking skills and metacognitive awareness. Studies on other learning models need to be carried out to add references in organizing the learning process.

The research aimed to know the effect of Problem-Based Learning model supported by problem card media on cognitive learning outcomes and environmental care attitude of the TNWK by students of SMPN 1 Labuhan Ratu. The research design used in this study is the non-equivalent control group design. The research took sample of 60 students consisting of class VII 5 as a control class and VII 6 as an experimental class with cluster random sampling technique. The type of data in this research is quantitative data in the form of score on students’ cognitive learning outcomes and environmental care attitude of the TNWK. The data were obtained from environmental pollution questions and attitude questionnaires were analysed using the Independent Sample T-test. The results showed that at the 5% significance level, the Sig. score was obtained (2-tailed) 0,000<0,05 for cognitive learning outcomes and 0,004<0,05 for environmental care attitude. So it can be concluded that there is a significant effect of Problem-Based Learning model supported by problem card media on cognitive learning outcomes and environmental care attitude of the TNWK.
