Abstract

Penelitian untuk mengidentifikasi keberadaan air tanah dan kedalaman akuifer telah dilakukan di wilayah KEK Arun Lhokseumawe Provinsi Aceh dengan kondisi geologi daerah penelitian adalah batuan lanauan dan batuan lempung serta geomorfologinya berupa perkebunan dan sungai buatan. Penelitian ini mengaplikasikan metode geolistrik resistivitas 2D dengan konfigurasi Wenner-Schlumberger. Akuisisi data di lapangan menggunakan alat SuperSting R8 yang keseluruhannya mempunyai 4 lintasan pengukuran dengan lintasan 1 dan 2 memotong lintasan 3 dan 4, panjang masing-masing lintasan pengukuran tersebut adalah 400 m. Pemprosesan data Hasil akuisisi di lapangan menggunakan software Res2dinv untuk menampilkan model 2D bawah permukaan di lokasi penelitian. Hasil interpretasi menunjukkan lintasan L1 pada kedalaman sampai dengan 70 m terdapat lempung berpasir, lanauan dan gravel. Terdapatnya pengaruh instrusi air laut pada kedalaman 25 m yang ditandai dengan nilai resistivitas 1 Ώm. Lapisan akuifer di identifikasi pada jarak bentangan 100 - 200 m dan pada kedalaman 60 m dengan nilai resistivitas 30 Ωm. Penampang lintasan 3 dan 4 tidak menunjukkan adanya lapisan akuifer yang layak untuk diexploitasi pada lintasan tersebut. Interpretasi lintasan L4 menunjukkan adanya intrusi air laut yang besar pada lapisan pertama. Terdapat 3 lapisan yang kontras yaitu lapisan lempung berpasir, gravel/lempung lanauan dan batuan dasar. Lapisan akuifer pada lintasan 4 diinterpretasikan berada pada kedalaman 70 m dengan nilai resistivitas 30 Ωm. Rekomendasi yang paling layak untuk lokasi pengeboran yaitu pada lintasan 4 pada jarak bentangan 180 m dengan jenis akuifer tertekan. The research to identified ground water and depth of aquifer was conducted in KEK Arun Lhokseumawe Aceh Province. The geology contained siltstone and clay with geomorphology area are plantation and artificial river. The 2D resistivity acquisition was using Supersting R8 equipment with Wenner-Schlumberger array. There are 4 survey lines that conducted in the area where line 1 and 2 were crossed with line 3 and 4. The length of each line is 400 m respectively. The data processing was using Res2dinv software to shows 2D subsurface model. The result shown that line 1 is sandy clay, siltstone and gravel at depths up to 70 m. It was influenced by sea water at depth 25 m with resistivity value of 1 Ωm. The aquifer layer was identified at depth 60 m with resistivity value of 30 Ωm. However, line 3 and 4 were presented that the area surveys are suitable for exploration which have not indicate the existence of an aquifer layer. In the last line, it shown sea water intrusion at the first layer. There are 3 layers that contained in line 4 which is clayey sand, gravel and bedrock. The aquifer layer at Line 4 was interpreted at depth 70 m with resistivity value of 30 Ωm. The most feasible recommendation for a drilling location is on Line L4 at a distance of 180 m with a confined aquifer type. Keywords: Aquifer, Resistivity, Lhokseumawe, ground water, sand

Abstract

Physics learning is a complex subject that required an extraordinary understanding. Based on the results of interviews at SMAN 4 DKI Jakarta, in Banda Aceh, critical thinking skill tests have not been carried out and student responsibility in following lessons.  This research aims to optimize physics learning through the PjBL-STEM model, in order to improve students' critical thinking skills and lack of sense responsible attitudes. The research design that used in this research was a one group Pretest and Post-Test Design, it was involving 120 students in grade XI. The data collection techniques are carried out through observation, interviews, questionnaires and tests that are prepared based on indicators of critical thinking skills. This research data was analyzed using the average test, N-gain and paired sample t-test. The instruments used critical thinking skills tests and responsibility attitude questionnaires. The research results show that the average N-gain 0,67 is categorized as currently. The results of the responsible attitude questionnaire are in the effective category with an average of 367.2, From the findings of this research it can be concluded that the PjBL-STEM model can optimize physics learning in improving critical thinking skills and attitudes of responsibility.

Abstract

The purpose of this study is to analyze the improvement of student's science process skills with the application of visual gaining knowledge media in science subjects. The research method used is an experiment with a quantitative approach. The research design employed in this study is true experiment. The study's target population were all students at SMP Negeri 11 Banda Aceh, while the instance selected in this research were 56 pupils making use of the non-simple random sampling method by means of proportional sampling. The instrument used was 20 items to measure science process skills with multiple choice diagnostic tests. The outcomes of research on science process skills in the experimental class for each indicator were obtained: observing by 31.76%, classifying by 39.99%, interpreting by 62.31%, predicting by 53.42%, asking questions by 27.27%, formulating hypotheses by 21.74%, designing experiments by 34.95%, using tools and materials by 25.83%, applying concepts by 15.46%, and communicating by 21.72%. The study's findings allow for the conclusion that the highest indicator of students' science process skills is in the interpretation indicator, but the least significant indication is in the communication indicator. Therefore, the implementation of visual learning media in science subjects can have a positive impact on improving students science process skills.
