Abstract

Dolphinear is an instrument for monitoring sound wave signals underwater. This study aims to see how the results of sound recording by Dolphinear type DE200 based on variations in distance and frequency of the sound source using the Audacity Software. In this study, the sound source will be generated through a waterproof speaker with a frequency variation of 100 Hz to 20 kHz. The distance between the sound source and the dolphinear is also varied from 1 to 5 meters. Audacity software is used to generate, record, and obtain the spectrum of the recorded audio sound signal. Based on the spectrum of the sound recorded by the DE200 dolphinear, frequency peaks close to the source frequency can be detected in recording using a 500 Hz sound source, but the main frequency peaks in the spectrum are difficult to detect in recording using sound sources above 500 Hz. In this study, it was also found that there is a limit to the recording ability of the dolphinear DE200 for frequencies above 18 kHz which is indicated by a decrease in intensity at that frequency.

Abstract

The use of software in the field of geophysics is often limited to the instantaneous use of interfaces without a deep understanding of the computational processes behind them. This leads to limitations in data interpretation and the development of new methods. To address this issue, it is necessary to explicitly visualize the data processing process through programming in order to strengthen computational thinking skills, which are one of the important competencies of the 21st century. This study aims to visualize the microseismic data processing process using programming in GNU Octave software. The method used is a simulation of microseismic data processing based on the HVSR (Horizontal to Vertical Spectral Ratio) approach, with field data collected from the Yogyakarta area. The processing is carried out by building a programming script in GNU Octave, the results of which are then compared with the Geopsy software as a verification tool. The research results indicate that data processing visualization using the HVSR method through GNU Octave can be performed effectively, and the results exhibit high consistency with the output from Geopsy. The dominant frequency on both curves is the same at a frequency of 1.59 Hz. In addition to the dominant frequency, the HVSR curve shape of both software also shows a similar trend pattern in the mid to high frequency range (around 2–10 Hz), where the amplification value decreases gradually. This demonstrates the accuracy of the developed script and proves that this approach can serve as an educational tool for understanding the functioning of geophysical software in a more transparent and in-depth manner. Programming with GNU Octave can be used as an efficient and accurate geophysical analysis tool. This provides opportunities for users, especially in academic environments with limited access to commercial software.

Abstract

The philosophy of existentialism emerged driven by the uncertain world conditions due to world wars. So existentialism is present as a thought movement that emphasizes human subjectivity and freedom. This study has a purpose for reflection. Reflection means the process of understanding events in the mind or experience that is owned. This study uses descriptive qualitative research. This study utilizes a literature search. The literature search process begins with key phrases such as “existentialism”, “education” and “awareness”. Man must exist, which means realizing that he exists to control himself and act on his behalf. The philosophy of existentialism talks about human existence, while talking about humans means questioning educational issues. Each person is unique, which is different from one another. Realizing this is important for students, parents, teachers, principals, board members, and all those involved in education. Education is expected to realize the "intensity of awareness" of students. So that they are aware of their responsibility to determine the life they will live themselves.   Filsafat eksistensialisme muncul didorong oleh keadaan dunia yang tidak menentu akibat perang dunia. Sehingga eksistensialisme hadir sebagai gerakan pemikiran yang menonjolkan subjektifitas dan kebebasan manusia. Studi ini memiliki tujuan untuk refleksi. Refleksi berarti proses memahami peristiwa dalam pikiran atau pengalaman yang dimiliki. Studi ini menggunakan penelitian deskriptif kualitatif. Studi ini memanfaatkan pencarian literatur. Proses pencarian literatur dimulai frasa kunci seperti “eksistensialisme”, “pendidikan” dan “kesadaran”. Manusia harus eksis yang artinya menyadari bahwa dia ada untuk menguasai dirinya dan bertindak atas nama dirinya. Filsafat eksistensialisme berbicara tentang keberadaan manusia, sedangkan berbicara tentang manusia berarti mempersoalkan masalah pendidikan. Setiap pribadi adalah unik yakni berbeda-beda satu dengan yang lainnya. Menyadari hal tersebut menjadi penting bagi seorang siswa, orangtua, guru, kepala sekolah, anggota dewan, dan semua yang terlibat didalam pendidikan. Pendidikan diharapkan dapat mewujudkan “intensitas kesadaran” siswa. Sehingga sadar akan tanggungjawabnya untuk menentukan kehidupan yang akan dijalaninya sendiri.

Abstract

Building damage caused by earthquakes is more prevalent in the sedimentary areas of Yogyakarta City compared to the hilly regions of Wonosari and Kulonprogo, which have harder soil layers. The campus of Universitas Sarjanawiyata Tamansiswa (UST) is one of the campuses located in Yogyakarta City, where the regional geology is dominated by the Merapi Young Volcanic Deposits Formation. The UST campus area is vulnerable to earthquakes due to its proximity to an active seismic zone, making earthquake vulnerability mapping based on microseismic data an important necessity to support disaster mitigation efforts. The microseismic method was used in this study, while data analysis employed the Horizontal-to-Vertical Spectral Ratio (HVSR). Microseismic measurements were chosen because they have the advantage of not damaging the surface conditions of the ground, thus preserving the environment, and are easy to use in urban areas. The research method stages include survey design, field data collection, data processing and interpretation, and the creation of earthquake vulnerability maps. Data points were collected from 7 locations covering the Universitas Sarjanawiyata Tamansiswa campus area. The research results indicate that the study area has a dominant frequency value ranging from 1.10 to 2.74 Hz. Meanwhile, the amplification value ranges from 1.25 to 2.2. The sediment thickness of the study area ranges from 32 to 79 meters. The Seismic Vulnerability Index (Kg) of the study area ranges from 0.57 to 4 on a low to high scale. Based on the dominant frequency values, amplification, and seismic vulnerability index, the areas of the UST campus that are more vulnerable to earthquakes are the northern, eastern, and central parts, while the southern part is relatively safer.

Abstract

The study of dynamic electrical physics among first-semester students is often unpopular because it is considered abstract and difficult to relate to real-world applications. To foster a positive attitude and interest in the subject matter, contextual and technology-based learning strategies are needed. This study aims to apply a simulation of a BLDC electric motor using the open-source software GNU Octave in the context of electric vehicles, as well as to describe students' affective responses after participating in the learning activity. The study employs a quantitative descriptive approach with participants being students from the Physics Education and Vocational Mechanical Engineering Education programs. The simulation was developed based on the mathematical model of the BLDC electric motor and visualized using numerical methods in GNU Octave. After participating in the simulation-based learning activity, students were asked to complete a questionnaire measuring affective aspects such as interest, motivation, and attitude toward physics learning based on applications. The questionnaire results indicated that the majority of students responded positively to the use of simulations. The research results indicate that over 90% of students demonstrated interest, motivation, and positive attitudes toward simulation-based physics learning on electric motors. Students also evaluated GNU Octave as an attractive, free, and relevant tool for learning needs in the digital age. Thus, the application of GNU Octave as a simulation medium not only supports conceptual understanding indirectly but is also effective in fostering students' affective aspects toward physics and electric vehicle technology learning.

Abstract

Microtremor has been widely used to determine soil characteristics and dynamics. In this research, particle motion analysis was conducted on 15 microtremor data recordings around the surface of the Bribin Underground River in the Gunungsewu Karst Area. Spectrum analysis was conducted as a basis for determining the frequency range for the particle motion analysis process. Particle motion analysis was only carried out on the horizontal component of the microtremor signal which is expected to provide a representation of the river flow path. The results of particle motion analysis of microtremor recordings in the surface area of the Bribin Underground River show that there are only two points that have a motion-resultant oriented to certain direction, which is perpendicular to the river channel.The points are A4 and B4 which are located in the eastern part of the river flow path.

By utilizing the idea of coalgebra as a special case of commodules, the idea of clean coalgebra is the same as clean commodules. Then the idea of bi-clean Hopf module is defined through the cleaness properties of its basic structure as a clean module and also as a clean commodity, and the basis of mathematical thinking is generalization by combining the cleaness properties of its basic structure as a clean module and as a clean commodity. The idea and mathematical reasoning of the hopf clean module follow the idea and mathematical reasoning of the hopf bi-clean module.
