Abstract

Fisika menganut metodologi ilmiah (sains) yang memuat tiga kegiatan terpadu dan membentuk daur (cycles) empirico-logico-verification yang pertama kali dirintis oleh I. Newton yaitu (1) pengamatan gejala-gejala alam (kegiatan empiris melalui fisika eksperimen), (2) Penalaran untuk menjelaskan hasil pengamatan tersebut dan ekstensinya sehingga mampu menghasilkan ramalan mengenai gejala baru (kegiatan berlogika melalui fisika teori) dan (3) pengujian mengenai kesesuaian ramalan tersebut dengan realitas alam (kegiatan verifikasi melalui fisika eksperimen). Keberadaan laboratorium di sekolah-sekolah menjadi kunci keberhasilan dalam memperkenalkan tiga kegiatan terpadu tersebut. Sekolah Menengah Atas Negeri (SMAN) 2 Harau, Kabupaten Lima Puluh Kota merupakan sekolah di bawah naungan Provinsi Sumatera Barat dengan jarak sekitar 138 km dari Jurusan Fisika FMIPA Universitas Andalas tepatnya berada di Kecamatan Harau. Dari informasi yang diperoleh masih terbatasnya sarana dan prasarana seperti jumlah peralatan praktikum. Berdasarkan hal tersebut, tim pengabdian Jurusan Fisika FMIPA Universitas Andalas akan melaksanakan rangkaian kegiatan pengabdian masyarakat di SMA N 2 Harau dengan pemanfaatan media online salah satunya Phet- Simulation. Hasil pengabdian menunjukkan 90 % siswa mengatakan setuju dan sangat setuju bahwa kegiatan seperti ini memberikan manfaat bagi pemahaman materi di bidang Fisika. Kegiatan seperti ini perlu dilakukan lebih banyak oleh Tim Pengabdian sehingga masyarakat merasakan keberadaan perguuruan tinggi yang ada didaerahnya. Kata kunci: PhET Colarado; Simulasi Fisika; dan Pengabdian Masyarakat

Abstract

A research study was conducted to estimate and visualize 2D vectors of blood flow in the heart using image processing algorithms to determine Doppler velocity at each point. The study used secondary data from ten patients who provided informed consent, encompassing healthy and unhealthy hearts. ECD image data were collected using a Philips epiq 7C machine in DICOM format. The image processing tasks, including area segmentation, flow velocity analysis, and area smoothing, were carried out using MATLAB R2016b software. These processes aimed to eliminate noise and other disturbances, enhancing the accuracy of blood flow velocity estimation in the heart. The study's findings included estimations and 2D vector visualizations representing the average blood flow velocity at each point within the heart. These achievements were made possible using image processing techniques to correct the acquired images, ensuring precise measurement of blood flow speed. Among the collected data, one patient exhibited indications of a healthy heart, with an average blood flow velocity of 40.2513 cm/s, a maximum speed of 68.5807 cm/s, and a minimum speed of 33.6971 cm/s. Deviations from the normal range of blood flow speeds were considered as potential abnormalities in heart health.

Abstract

The concept of electromagnetic induction is very important in understanding and developing modern electrical technology. Some factors cause students to often find it difficult to understand electromagnetic induction material in school is that this material involves abstract concepts such as magnetic flux, magnetic field changes, and emf. For some students, understanding these concepts may be difficult due to a lack of direct experience or concrete representations. Enrichment of physics material on electromagnetic induction has been implemented at SMA N 1 Gunung Talang. This service activity aims to improve students' understanding of the basic concepts of Electromagnetic Induction in Class XII. This service consists of three stages including: preparation, implementation and evaluation. The evaluation of this activity was carried out by comparing the pre-test results before enrichment and the post-test scores of students after being given enrichment material by the lecturer (service team). The results obtained show an increase in student knowledge towards understanding the concept of electromagnetic induction. This service activity can be an effort for school and university cooperation to support student success in understanding physics concepts that are considered complicated

Abstract

Nobita Hill, a tourist site in Padang City, is undergoing development as a tourist destination that offers a bird's-eye view of Padang City. Unfortunately, the hilly topography with steep slopes increases the risk of landslides in this area. In order to address the problem, the community service team from the Physics Department of Andalas University has carried out a six-month community service program from July to December 2022. It focused on disaster awareness education and used a qualitative approach. This activity aims to socialize disaster mitigation efforts, especially those related to landslides and earthquakes, considering that Padang City is also prone to earthquakes. The results of this activity showed an increase in the knowledge of the local community after the socialization, but repeated activities are needed to achieve optimal results. This ongoing activity is essential to ensure continuous improvement in the community's understanding of disaster mitigation and to support efforts to make Bukit Nobita a disaster-resilient area. Thus, this activity makes a positive contribution to shaping a safe, sustainable, and disaster-resilient tourism environment.
