Abstract

This study aims to determine the depth of the aquifer layer in the Muara Batu and Dewantara sub-district as a source of groundwater that can be used continuously. The identification of this aquifer layer is based on the results of the resistivity values of subsurface rocks measured using the electrical resistivity method of the Schlumberger array. Data acquisition was carried out on 3 lines (MB1, MB3, and MB4) with a length of 330 m each. The variations in the resistivity values of the rocks obtained were modeled in the form of a 2D cross-section using the Res2DInv software, thus providing an overview of the subsurface for groundwater exploitation. The cross-sectional model obtained shows that the shallow aquifer layer is at a depth of 20-52 m (2-12 Ωm) on the MB1 and a depth of 60 m on MB3 and MB4. The low resistivity value 12 Ωm on the MB1 indicates that the subsurface is generally composed of water-saturated rock layers.

Abstract

Remaja sekarang sangat membutuhkan pendidikan yang mampu mempertimbangkan seluruh cakupan aspek karakter, dikarenakan rusaknya karakter remaja yang bisa diakibatkan oleh perkembangan teknologi. Usaha untuk membentuk karakter remaja yang baik dan bermutu dapat dilakukan di satuan pendidikan. Salah satunya penerapan karakter disekolah menengah atas pada pelajaran fisika. Penelitian ini dilakukan pada beberapa sekolah menengah atas di kawasan Aceh Utara. Tujuannya yaitu untuk mengetahui tingkat pembentukan karakter remaja dalam pembelajaran fisika di kawasan Aceh Utara. Metode yang digunakan pada penelitian ini adalah pendekatan deskriptif kualitatif. Subjek yang dijadikan penelitian yaitu para siswa sekolah menengah atas di kawasan Aceh Utara. Teknik pengumpulan data berbentuk angket tertutup melalui penyebaran link google form kepada responden untuk mendapatkan data-data secara tidak langsung dari pernyataan-pernyataan di angket tersebut. Adapun berdasarkan hasil penelitian, didapatkan data yang diperoleh dari pembentukan karakter remaja pada sekolah menengah atas kawasan Aceh Utara sudah dapat dibentuk dengan baik. Dibuktikan dengan adanya indikator-indikator nilai karakter yang mencakup aspek jujur, disiplin, bertanggung jawab, peduli, percaya diri, kreativitas, dan gotong royong. Karakter-karakter tersebut dapat dikembangkan dengan baik oleh para remaja.

Abstract

This research aims to investigate the influence of the project-based learning instructional model on students' science literacy skills and self-efficacy in rectilinear motion kinematics at SMA Negeri 1 Lhokseumawe. The research design employed is a quasi-experiment in the form of a Nonequivalent (Pretest And Posttest) Control Group Design. The study population consists of ten classes of eleventh-grade IPAS students at SMA Negeri 1 Lhokseumawe. The sampling technique used is purposive sampling, with XI IPAS 1 (36 students) selected as the experimental class using the PjBL learning model and XI IPAS 4 (36 students) as the control class using the direct instruction learning model. Data collection is conducted through a 10-item essay test and a non-test questionnaire on student self-efficacy comprising 20 statements. Data analysis utilizes the Manova test. This research indicates that the PjBL learning model impacts science literacy skills based on the Manova test results, which show 0.000 < 0.05, signifying a significant influence on the average science literacy skills. The PjBL learning model also influences self-efficacy according to the Manova test results, which demonstrate 0.004 < 0.05, indicating a significant impact on the average self-efficacy. Furthermore, the PjBL learning model affects science literacy skills and self-efficacy, as evidenced by the important results of the Manova test, 0.000 < 0.05. Therefore, it can be concluded that the null hypothesis  is rejected, and the alternative hypothesis is accepted. Based on this, it can be inferred that the PjBL learning model influences the science literacy skills and self-efficacy of grade XI students at SMA Negeri 1 Lhokseumawe.Keywords: Project-Based Learning Model, Science Literacy Skills, Self-Efficacy

Abstract

Scientific literacy is scientific knowledge that is used to identify various questions and draw conclusions based on facts. Based on the interview results, students' scientific literacy abilities were not optimal, this research was conducted with the aim of finding out the effect of the inquiry training model assisted by Assembler media on students' scientific literacy abilities. This research is quantitative research using quasi-experimental research and a nonequivalent control group design. The sampling technique chosen was a total sampling of 48 students, namely 24 students in class XI-IPA 1 as the control class and 24 students in class XI-IPA 2 as the experimental class. The instruments used in this research used non-test instruments in the form of interviews and test instruments in the form of pretest and posttest questions in the form of essays totaling 10 questions. Meanwhile, data analysis uses prerequisite tests which include normality, homogeneity and hypothesis testing. The research results showed that the average scientific literacy pretest score for the experimental class, namely class XI-IPA 2, was 35.21 with a posttest score of 76.46, while the control class, namely class the results of the statistical hypothesis test obtained a Sig value. (2-tailed) of 0.000 with a significance level of 0.05. It can be concluded that there is an influence of the inquiry training model assisted by assembler media on students' scientific literacy abilities.

Abstract

This research aims to determine the feasibility and practicality of STEM-based LKPD learning media products on thermodynamics material as a medium that makes it easier for students to study thermodynamics material. The instrument used in the research is a feasibility and practicality questionnaire which will be given by material and media experts and given to teachers in the field of physics and students in class XI IPA 2 MAS Syamsuddhuha. This development research method refers to Research and Development (R&D) with the ADDIE model (Analysis, Design, Development, Implementation and Evaluation). The research results showed that experts in the media field gave a feasibility assessment of 92.3% with a very feasible category, experts in the material field gave an assessment of 88.6% with a feasible category and teacher responses gave an assessment of 86% with a very practical percentage. The results of small-scale product trials gave an assessment of 86.9% in the very practical category and the results of large-scale product trials gave an assessment of 84% in the very practical category.
