Abstract

Pada umumnya siswa kurang tertarik untuk belajar fisika karena merupakan salah satu mata pelajaran yang dianggap sulit. Mempelajari fisika merupakan suatu petualangan. Proses belajar mengajar (PBM) di sekolah masih banyak menggunakan model konvensional yang dirasa membosankan dan akibatnya banyak pelajar masa kini sulit memahami pelajaran yang dipelajari di sekolah. Oleh karena itu, perlu adanya pengembangan PBM di luar kelas salah satunya dengan memberikan bimbingan belajar (bimbel) tambahan. Perkembangan teknologi yang semakin pesat dimanfaatkan oleh bidang pendidikan yaitu dengan menerapkan pembelajaran berbasis online yang dikenal sebagai bimbingan belajar online (bimbel online). Metode yang digunakan pada penulisan ini yaitu metode penelitian kualitatif dengan menggunakan pendekatan Studi Kepustakaan (Library Research). Sumber data yang digunakan dalam penelitian ini adalah data sekunder. Teknik analisis data yang digunakan dalam penelitian ini adalah metode analisis isi (Content Analysis). Media aplikasi bimbingan belajar online menjadi salah satu alternatif yang dapat sangat berperan membantu siswa dalam belajar terutama pada pembelajaran fisika. Hasil akhir yang pastinya ingin didapatkan yaitu siswa tidak lagi kesulitan dalam memahami pelajaran fisika yang dipelajari di sekolah, serta meningkatnya semangat, minat, dan bakat siswa dalam pemecahan masalah terkait fisika.

Abstract

Research on seismicity parameters in the East Nusa Tenggara region can use the a-value and b-value parameters as the main earthquake precursors. The two parameters are seismic activity level and relief level. In general, both parameters use the relationship between between the frequency of earthquake occurrences and magnitude earthquake from the Guternberg-Ritcher law in the form of a graph. This study uses secondary data from the USGS earthquake details which was processed with ZMAP 6.0 software with the maximum likelihood method. Statistics of earthquakes with a magnitude of 4,5 ≤ Mw ≤ 7,9 as many as 1685 events and a depth of 675.5 km in the period 1990-2020. Based on data analysis, the Gutenberg-Ritcher equation is log N (M)=8.72-1.19M where b-value = 1.19, a-value = 8.72, a-value (annual) = 7.23, fractal dimension = 2.38. From this reason, seismic activity in the East Nusa Tenggara region is relatively high, stress levels are low and the source of the earthquake is the main faults cause structural earthquakes and even tsunamis in the seismic tectonics of the arc area basin in front of the Australian plate subducting along the subduction zone in the northern Indonesia. Therefore, the seismic parameters can be used as a long-term earthquake disaster mitigation through knowledge such as socialization before a disaster, during a disaster, and after a disaster by considering the local wisdom of the local community.

Abstract

Research on the estimation of groundwater potential and its depth has been carried out in Nglanggeran Kulon which is the Nglanggeran Ancient Volcano Tourism Village in Gunung Kidul. The large number of tourists who visit makes the need for groundwater in this location also increases but has not been matched by its availability. This area is also a district that almost every dry season experiences a water crisis. The purpose of this study was to find out the potential presence of groundwater and its depth. This is related to the efforts of local residents who want to build new wells. The method used is the geoelectric resistivity method with the Shlumberger configuration. This method exploits the electrical properties of the rock beneath the surface. The physical parameter measured is the resistivity value to create a subsurface geological model in the form of a 1D model. The length of the stretch carried out is 125 m at two measurement points. The results of this study indicate that 1st point has two layers of rock and no groundwater potential is found. 2nd point has four layers of rock. Groundwater potential is found in 2nd layer because it has a low resistivity value of 9.89 ꭥm at depths ranging from 5-9 meters with a thickness of about 4 meters. So that the location of the 2nd point is more recommended for making new wells.

Abstract

The skill to think analytically is an important skill for students to have, where the skill to think analytically helps students solve problems in science lessons that require an analytical skill to solve them. The research method is qualitative with a naturalistic design. This research was conducted at some Junior High schools in Ponorogo using the purposive sampling technique. Data were collected using in-depth interviews, observation, and documentation, then analyzed using quantitative descriptive and qualitative descriptive. This study aims to determine the profile of students' analytical thinking skills in solving problem-based problems in the grade 8th at pressure material and determine the pattern of its relationship with scientific exploration. The results showed that: 1) the profile of the analytical thinking skill in terms of the learning styles of students, namely the visual style subjects intend to explain what is known through the direct explanation in more detail, the audiovisual subjects are more likely to form simpler patterns with reasoning patterns generalization and on kinesthetic subjects tend to apply different (unique) concepts, but still have a relationship with the problem, 2) the pattern of the relationship between analytical thinking skills and learning styles, namely the exploration of science, which includes aspects of experience, reasoning, modalities, and the mindset of students. Through the results of this study, it is hoped that it can provide theoretical and practical insights for educators in determining approaches and strategies for achieving science analytical competence according to students' learning styles at school.
