Abstract

The current research has primary objective that is to assess the effect of implementing the Inquiry-Based Learning Model in enhancing students' academic performance in the field of Science at SMA Smart Indonesia. The Inquiry-Based Learning Model promotes proactive student engagement in exploring, gathering, and interpreting information through independent investigation. The study utilized a quasi-experimental design encompassing pre-test and post-test phases. The participants were selected randomly via a simple random sampling technique. The acquired data underwent analysis using the N-Gain method (T-test). The outcomes revealed a noticeable improvement in the academic performance of students in the experimental group who were exposed to the Inquiry-Based Learning Model, particularly in the context of the human respiratory system. Furthermore, the null hypothesis (H0) was invalidated, as was proven by the 2-tailed Significance value of 0.000 that was smaller than 0.05. This discovery underscores the substantial positive impact of applying the Inquiry-Based Learning Model on enhancing students' academic achievements when compared to conventional teaching methods employed in the control group. In conclusion, this study highlights the significant potential of integrating the Inquiry-Based Learning Model into the Natural Science curriculum at the secondary school level, which could potentially elevate the standard of education and overall student learning accomplishments.

Abstract

The Kampar River is one of the rivers in the upper reaches that has caused pollution due to local communities such as excessive activity and gravel and sand mining. The purpose of this study was to determine the density of phytoplankton in the Kampar River in Koto Kampar Hulu Subdistrict, Kampar Regency. Purposive sampling was used to determine observation stations, which took into account habitat types and biological parameters observed such as species composition, abundance, and diversity index. The findings revealed that five classes of algae were discovered in Kampar Chlorophyceae, Cyanophyceae, Zygnematophyceae, Bacillariophyceae, and Xanthophyceae. The abundance of phytoplankton in the Kampar River's waters is classified as moderate fertility, ranging from 2,419.96 cells/liter to 3,629.96 cells/liter.

Abstract

ABSTRAK: Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran sains teknologi masyarakat berbasis proyek terhadap hasil belajar siswa pada materi pencemaran lingkungan di kelas VII SMPN 30 Pekanbaru tahun ajaran 2015/2016. Penelitian ini dilaksanakan pada semester genap bulan Maret 2016. Penelitian ini merupakan kuasi eksperimen dengan nonequivalent pretest-posttest control group design. Sampel penelitian adalah siswa kelas VII1 dengan jumlah siswa 38 dan VII6 dengan jumlah siswa 34, yang diambil dengan teknik simple random sampling. Pengumpulan data dilakukan melalui pretest, posttest dan lembar observasi aktivitas guru dan siswa.Teknik analisis data yang digunakan dalam penelitian ini berupa t-test. Rerata N-Gain pada kelas eksperimen 0.66 (kategori sedang), sedangkan pada kelas kontrol 0.44 (kategori sedang). Berdasarkan uji hipotesis komparatif uji-t terdapat perbedaan yang signifikan antara N-gain kelas kontrol dan kelas eksperimen. Dengan demikian dapat disimpulkan bahwa terdapat pengaruh model pembelajaran sains teknologi masyarakat berbasis proyek terhadap hasil belajar siswa pada materi pencemaran lingkungan di kelas VII SMPN 30 Pekanbaru

Abstract

Pembelajaran yang berorientasi atau berpusat pada guru membuat siswa tidak mengerti terhadap materi yang disampaikan oleh guru sehingga mereka cenderung bertanya kepada temannya. Hal ini menyebabkan permasalahan terhadap hasil belajar siswa. Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Tutor Sebaya berbantuan media Standing Banner terhadap hasil belajar siswa pada materi sistem pencernaan manusia kelas VIII SMP Negeri 18 Pekanbaru Tahun Pelajaran 2018/2019. Penelitian ini dilaksanakan pada semester ganjil bulan Desember tahun pelajaran 2018/2019. Desain penelitian yang digunakan adalah Quasi Eksperimen dengan The Matching Only Pretest-Posttest Control Group Design. Sampel dalam penelitian ini adalah kelas kontrol VIII 2 dengan jumlah 36 siswa dan kelas eksperimen VIII 1 dengan jumlah 35 siswa. Sampel ditentukan dengan menggunakan teknik Purposive Sampling. Pengumpulan data dilakukan melalui pretest, posttest dan lembar observasi berupa aktivitas guru dan siswa. Teknik analisis data menggunakan uji-t Independent Samples Test. Rerata N-Gain pada kelas kontrol adalah 0.28 kategori rendah dan kelas eksperimen adalah 0.63 kategori sedang. Berdasarkan analisis hasil uji-t menunjukkan perbedaan yang signifikan antara kelas kontrol dan eksperimen. Dari hasil penelitian dapat disimpulkan bahwa terdapat pengaruh pembelajaran Tutor Sebayaberbantuan media Standing Banner terhadap hasil belajar siswa pada materi sistem pencernaan manusia kelas VIII SMP Negeri 18 Pekanbaru tahun pelajaran 2018/2019.

Abstract

A person's success in mastering a material is caused by the belief he has, because it is this belief that will cause a person to behave in such a way that the belief will materialize. One source of belief is the level of self-confidence. ability (self-efficacy). The Scientific Critical Thinking (SCT) model is a model that can be applied to material on the human respiratory system in class A1 and A2 biology lessons at Lancang Kuning University. This study aims to determine critical thinking skills, communication skills and self-efficacy of biology students in the application of the SCT model to the material on the respiratory system. The method in this study was a quasi-experimental study with a post-test nonequivalent control group design. The sample of this study were students in class A1 biology (experimental class) and class A2 biology (control class). Retrieval of data in research using test and non-test techniques. Data analysis techniques used in this study are descriptive and inferential. The results showed that (1) there was an increase in critical thinking skills (2) an increase in communication skills and (3) an increase in self-efficacy. The experimental class was better than the control class in training biology students' critical thinking skills, communication skills, and self-efficacy in learning material on the human respiratory system.

Abstract

This research aims to identify types of aeroplankton as air quality parameters in the Pekanbaru area. Aeroplankton samples were collected using the Purposive Sampling method where samples were taken 1x24 hours for 20 days in 2 different sub-districts, namely Sukajadi District and Tenayan Raya District. Identification and counting of aeroplankton is carried out in the laboratory. The results showed that the abundance of aeroplankton in Sukajadi subdistrict was higher than in Tenayan Raya subdistrict. In both sub-districts, the abundance of aeroplankton is dominated by the phytoplankton and zooplankton groups. Where aeroplankton can be the basis for air quality parameters in the two sub-districts.
