Abstract

This Research is aimed for knowing, (1) the implementation of contextual learning by using Batik Semarangan for physics material especially temperature and heat, (2) the improvement of students’ learning achievements after the application of contextual learning by using Batik Semarangan, and (3) the students’ responses after being given contextual learning by using Batik Semarangan. This research mix methods, namely quantitative and qualitative. This research was conducted in two classed at SMK Walisongo Semarang for student class X TKJ Telkom 1 as experimental class and X TKJ Telkom 2 as control class. The identification of local potential of Batik Semarangan was carried out by using interview and observation technique which were then analyzed qualitatively and the result was substituted to physics material, namely temperature and heat.  Furthermore, learning achievements were assessed from sides of cognitive, affective and psychomotor.  The result showed that contextual learning by using Batik Semarangan was effective for improving cognitive learning achievements as proved by experimental class having value of 0.79 which was higher than the control class of 0.57. In addition, the result showed that contextual learning by using Batik Semarangan was effective in improving effective learning achievements as proved by the experimental class average of 86.55 which was higher than the control class of 76.73. The result also showed that contextual learning by using Batik Semarangan was effective in improving psychomotor learning achievements as proved by the experiment class average score 33.3 higher than control class 25.4. The implementation of contextual learning by using Batik Semarangan got a positive responses by students because it made them easier to understand concepts, to be more skilled, and increased students’ interest in the learning process. Based on the result, it can be concluded that contextual learning with the use of Batik Semarangan can be applied to study temperature and heat material in classroom. Contextual learning with the use of Batik Semarangan can improve students’ learning achievement. Contextual learning with the use of Batik Semarangan got a good response by students.

Abstract

This research is motivated by the lack of digital literacy and the complexity of students in the process of teaching and learning activities. In the learning process during PPKM (Enforcement of Community Activity Restrictions) students do online learning at home, often students who are not active are found. In this case, the teacher's role changes from the main role of providing information to being a facilitator in thinking, reflecting and collaborating findings. The use of PhET virtual laboratory media can help improve technological literacy. The purpose of this study was to analyze the effectiveness of the Problem Based Leaning model assisted by the PhET virtual laboratory on student learning outcomes. PhET simulation is an interactive animation that is accessed online and offline using Java and Flash software. The method used is quantitative research with a one-shot case study design. Class X MIPA 7 was used as the experimental class and class X MIPA 8 was used as the control class. The effectiveness of the Problem Based Leaning model assisted by the PhET virtual laboratory in the experimental class obtained a classical completeness score of 83%, while the control class was far below the classical completeness value of 55%.

Abstract

This study aims to develop a five-tier form of fluid misconception diagnostic assessment and to reveal the profile of student’s conceptual understanding in maritime-based schools in the city of Tegal. This study used a 4D model (defining, designing, developing, and disseminating). The sampling technique used purposive sampling. The research samples were Bahari Vocational School Tegal, Al Maarif Vocational School Tegal, and Nahdlatul Ulama Senior High School Tegal. Methods of data collection used documentation, questionnaires, tests, and interviews. Expert validation states that the instrument was valid, has good readability, was easy to understand, and the sentence structure was correct. The reliability of the instrument is 0.958 and declared reliable. A total of 39 questions were categorized as medium, and one question was easy. The discrimination power of the questions obtained was that 30 questions were accepted, eight questions were received with a little improvement, and one question needed improvement. Seventy student misconceptions were identified from seven fluid sub-concepts. The biggest misconception, as much as 46.5% was found in the buoyancy sub-concept, while the smallest misconception was found in the application of Pascal's law at 35.2%. The most dominant misconception is that the deeper a point in the fluid is, the greater the buoyancy. Students assume that the greater the depth, the greater the fluid pressure, so that the buoyancy force is greater. Students believe that buoyancy is influenced by fluid pressure. This misconception is influenced by conceptual appreciation and intuition in daily life.

Abstract

Pendugaan struktur lapisan bawah permukaan lahan gambut di Desa Arang Limbung telah dilakukan dengan menggunakan metode geolistrik tahanan jenis (resistivitas). Penelitian ini bertujuan untuk memberikan informasi terkait struktur tanah dalam rangka persiapan perancangan bangunan di lokasi penelitian. Pengambilan data dilakukan pada lima lintasan dimana panjang tiap lintasannya adalah 150 m dan jarak antar lintasannya adalah 15 m. Konfigurasi elektroda yang digunakan adalah konfigurasi Dipole-Dipole dengan spasi elektrodanya adalah 15 m. Nilai resistivitas semu diinversi menggunakan perangkat lunak Res2Dinv untuk mendapatkan distribusi nilai resistivitas bawah permukaan pada tiap lintasan. Berdasarkan distribusi nilai resistivitas tersebut dapat diinterpretasikan bahwa struktur lapisan bawah permukaan lahan gambut di Desa Arang Limbung terdiri dari empat lapisan utama yaitu gambut, tanah liat berpasir, pasir basah dan batuan bercampur pasir. Ketebalan lapisan gambut bervariasi dari 2,56 m hingga 16 m. Lapisan ini berada pada posisi paling atas.  Lapisan tanah liat berpasir berada pada kedalaman 2,56 m hingga 32,7 m. Lapisan pasir basah berada pada kedalaman 13,1 m hingga 30 m dan lapisan batuan bercampur pasir berada pada kedalaman 13,1 m hingga 32,7 m. Berdasarkan struktur ini maka direkomendasikan agar kedalaman pondasi bangunan yang akan dibuat di lokasi ini harus melebihi 16 m.

Abstract

The distribution of magnetic anomalies in Sambas Sea has been investigated using the Magnetic method. The raw data, which acquired, have been corrected using IGRF data and tie-line leveling to obtain the local magnetic field distribution. Then, from the corrected data obtained four anomalous zones. Next, a slice that lying on the anomalous zones (line AB, CD, EF, and GH) was made to obtain the subsurface structures which obtain using inversion method. The results show that the presence of magnetic anomalies at the lines AB, EF and GH (with susceptibility values between 1.2 to 19.2) due to the magnetite rock at the subsurface. Moreover, The presence of magnetic anomalies at the line CD (with susceptibility values of 0.3 to 3.5) is caused by ilmenite rock. The correlation coefficients between the observation data and calculated data for all lines are between 0.98 to 0.99.
