Abstract

Penelitian menggunakan citra Landsat-8 dan DEM telah dilakukan untuk analsis suhu permukaan tanah (land surface temperature/LST) dan kondisi geomorfologi kawasan geotermal Desa Tehoru. Penelitian ini dilakukan pada area dengan luasan 71,23 . Data citra Landsat-8 digunakan untuk analisis sebaran tutupan lahan dan LST. Seberan tutupan lahan diperoleh berdasakan klasifikasi nilai normalized difference vegetation index (NDVI). Data DEM digunakan untuk analisis kondisi geomorfologi daerah penelitian. Hasil analisis data menunjukkan bahwa area penelitian didominasi oleh lahan campuran dengan nilai NDVI rata-rata berkisar antara 0,302 – 0,338. Nilai LST di area penelitian berkisar antara C – C. Hasil analisis peta LST menunjukkan anomali LST tinggian lebih dominan pada kawasan permukiman. Anomali LST di sekitar titik manifestasi geotermal hanya terdeteksi sebagian kecil karena pengaruh tutupan lahan. Hasil analisis model topografi dan morfometri permukaan menunjukkan bahwa relief bergelombang dengan kemiringan lereng yang curam mendominasi daerah penelitian. Hasil analisis kelurusan geomorfologi, menunjukkan bahwa titik-titik manifestasi geotermal dominan berada pada daerah dengan tingkat kerapatan kelurusan yang tinggi. Penelitian ini secara langsung dapat memberikan informasi terkait tutupan lahan, LST, dan kondisi geomorfologi pada kawasan geotermal Desa Tehoru.

Abstract

Tiris area is one area that has geothermal prospects. Tiris area is located in the Tiris sub-district, Probolinggo regency, East Java. This study aims to identify the subsurface structure of the Tiris geothermal area using Topex gravity and DEM SRTM imagery data. The Topex gravity data obtained is still in Free Air Anomali (FAA) form, so it is necessary to make Bouguer and terrain corrections to get a complete Bouguer anomaly. A residual Bouguer anomaly is needed to study shallow subsurface structures. This anomaly is obtained by separating the residual and regional anomalies from the complete Bouguer anomaly using the moving average method. The study area has residual Bouguer anomaly values ranging from -0.5 to 2.9 mGal. The low residual Bouguer anomalies are seen in the body of the Lamongan volcano (LV) and the Tiris geothermal area (TGA). The study of subsurface structures is focused on the LV and the TGA through Forward 2D modeling. The A-A' cross-section illustrates the subsurface of LV, while the B-B' cross-section illustrates the subsurface of TGA. Cross-section A-A' modeling results show that the source of the low anomaly is in the second layer D2 = 1.24 g/  at a depth of 4.0 to 0.6 km below sea level and is suspected to be magma because it has a low density. Cross-section B-B' modeling obtained a low anomaly source at the second layer D2 = 2.03 g/  at a depth of 4.0 to 2.8 km below sea level and is suspected to be intrusive rock. The lineament display on the 2D of DEM SRTM map for the 45o and 135o azimuths shows that the TGA region has a high lineament density, and the orientation of the surface geological structure in the study area is dominant in a northwest-southeast direction.

Abstract

Kemampuan awal matematika mahasiswa dan tingkatan berpikir (aspek kognitif) dalam pemberian tes fisika menjadi perhatian khusus bagi pengajar dalam memantau dan mengontrol pencapaian hasil belajar fisika mahasiswa. Penelitian yang dilakukan bertujuan untuk menganalisis hubungan korelasional antara kemampuan awal matematika mahasiswa dengan pencapaian kognitif fisika umum. Capaian kognitif fisika yang dimaksud adalah kemampuan penyelesaian soal-soal tes fisika konsep gerak peluru. Sampel dalam penelitian yang dilakukan berupa sampel jenuh, yaitu 29 orang mahasiswa Pendidikan Matematika Semester II. Instrumen penelitian berupa dua bentuk tes essay yaitu tes kemampuan awal matematika dan tes kemampuan menyelesaikan soal fisika. Instrumen tes kemampuan matematika digunakan untuk mengukur kemampuan konsep aritmatika, aljabar dan trigonometri. Sedangkan tes kemampuan fisika digunakan untuk mengukur capaian kognitif fisika umum mahasiswa pada tingkatan berpikir aplikasi (C3) dan analisis (C4). Teknik analisis data dalam penelitian yang dilakukan menggunakan analisis deskriptif dan analisis inferensial. Hasil penelitian menunjukkan bahwa pencapaian kompetensi kognitif fisika umum mahasiswa untuk materi gerak peluru pada tingkatan berpikir C3 memiliki peresentase keberhasilan lebih tinggi yaitu 79,310% dibandingkan pada tingkatan berpikir C4 yaitu 24,137%. Hasil analisis korelasional menunjukkan adanya korelasi yang positif dan tinggi antara kemampuan awal matematika mahasiswa dengan pencapaian kognitif fisika umum pada materi gerak peluru dengan koefisien korelasi sebesar  = 0,895.

Abstract

This study aims to combine science process skills and students' cognitive abilities and improve students' cognitive learning outcomes by implementing the physics learning module in a cooperative setting. This research was conducted at SMA Negeri 3 Ambon, and this type is quantitative descriptive research. The design used in this study is the One-Group Pretest-Posttest Design. The sample in this study was class X MIA3, totaling 33 people, and it was taken using a purposive sampling technique. The instruments used in this study were test instruments, Student Activity Sheets, and non-test instrument rubrics. The research data shows that students' average initial cognitive ability is very low, achieving 28.78. In contrast, the final cognitive ability of students increases with achievement of 83.39. Student's cognitive ability through student worksheets has an average achievement of 85.51, while the average percentage of concept mastery with student worksheets is above 80%. Science process skills (SPS) with the highest average achievement are in conducting observations, namely 91.67, while the skill with the lowest is in planning experiments, namely 80.52. The difficulty level and complexity of the skills developed influence the high and low average SPS achievements. The results of the research data calculation obtained an increase in the achievement of learning outcomes of the N-gain value of 0.78, which indicates an increase in learning outcomes with a high category. The results of this study suggest that integrating SPS through learning modules in a cooperative setting can improve the physics learning outcomes on the solids elasticity concept.

Abstract

This study aims to develop a learning physics module through contextual learning design based on geothermal areas to improve scientific literacy ability and scientific communication skills on temperature and heat concepts. The sample in this study was 27 respondents of Mathematics Education STKIP Gotong Royong Masohi who are taking general physics subjects. The method used in this study is educational design research with the Plomp & Nieveen development model. The main instrument developed in this study is a prototype of a contextual physics learning module. The average percentage value of the validation results of the contextual physics learning module (prototype-1) from three experts on content (substance), language, and construct aspects is 88.41%, which shows that it is in the very valid category. The results of the trial of the practicality of the learning module in the one-to-one test obtained an average percentage value of 95.45%, and the results of the limited class trial (small group) received an average percentage value of 95.88%, which shows that the learning module developed is very practical. The results of the student's scientific literacy competency test at the field test (large class) showed an increase with an average N-gain of 0.75, which is in the high category; these results indicate that the learning physics module developed has been effective. The results of implementing the contextual physics learning module (prototype-2) in the field showed that students' average total scientific communication skills increased from 90.95 at the first meeting to 92.85 at the second meeting. Based on the results of the data analysis obtained, it can be concluded that the contextual physics learning module developed has met the valid, practical, and effective categories and can increase scientific literacy and scientific communication skills so that they are suitable for use in the learning process in the field.         Keywords: contextual physics learning, geothermal area, educational design research, science literacy and scientific comunication skills.DOI: http://dx.doi.org/10.23960/jpmipa/v25i2.pp986-1011
