https://journals.insparagonsociety.org/index.php/epicentrum/article/view/175
<p><span style="font-weight: 400;">Hand Sanitizer is a hand sanitizer that has antibacterial ability to inhibit and kill bacteria. There are two types of Hand Sanitizer, namely Hand Sanitizer gel and Hand Sanitizer spray. Currently, countries in Asia and Europe, including Indonesia, are being hit by disasters, one of which is the Corona virus. Based on this problem, an Arduino Uno-Based Automatic Hand Sanitizer was made using a Sensor which aims to reduce the spread of the virus by taking precautions such as cleaning hands, minimizing direct contact with other people, and reducing touching objects in public places that are often touched by many people. This tool uses an infrared sensor, where this sensor detects objects that are blocking it and the servo motor will rotate to press the bottle cap of the Hand Sanitizer. To make an Arduino Uno-Based Automatic Hand Sanitizer Using the FC-51 Infrared Sensor, this is done in several stages, namely making a program with Arduino.IDE to provide instructions that will be programmed to make it easier for users. </span></p> <p><strong>Keywords :</strong><span style="font-weight: 400;">Arduino Uno, Infrared Sensor, Servo Motor</span></p>Athaya AtsiqKhairul Wildani Akbar

https://journals.insparagonsociety.org/index.php/epicentrum/article/view/164
<p>The Covid-19 pandemic has affected almost all aspects of life, including the education aspect. To break the chain of spread of the Covid-19 pandemic, the learning system that was originally offline switched to online learning. In addition, the current swift currents of globalization have caused the erosion of cultural values. Therefore, we need media that can restore cultural values, especially Minangkabau culture in students' lives. This study aims to produce an android-based supporting mobile learning media on circular motion material for high school students in class X. This application is contextual and integrated with Minangkabau culture so that students will be more interested in studying physics. The method used in this study, namely the Four D research and development (RND) method includes Define, Design, Develop, and Dessiminate. The resulting application is one of the contributions to the development of learning media which is expected to be one of the right Physics learning solutions towards the golden Indonesia 2045.</p>Tegar Putra SocratesHabil IhsanMelfa RahmayaniFanny Rahmatina Rahim

https://journals.insparagonsociety.org/index.php/epicentrum/article/view/181
<p><span style="font-weight: 400;">Natural disasters are disasters caused by events or a series of events caused by nature, including earthquakes, tsunamis, volcanic eruptions, floods, droughts, hurricanes, and landslides. Landslide is a phenomenon that causes vertical movement of the ground surface, especially in sloped areas and often causes property and even life losses. The condition of vulnerability to landslides can be supported by natural factors such as rainfall, geological conditions, soil types, and slopes as well as factors that can come from nature with human intervention such as land cover. The combination of anthropogenic factors and natural factors is basically the main cause of the emergence of this level of landslide vulnerability so that it is important to design mitigation efforts, both preventive and repressive, by analyzing the potential for landslide disasters that may arise in an area. One of the steps to support this problem is to provide an overview related to disaster vulnerability analysis supported by the appearance of data information from the results of GIS processing (Geographical Information System). This research focused on 3 (three) nagari areas including the Sungai Pinang, Sungai Nyalo, and Mandeh. The results of the initial description of the research area based on regional characteristics from secondary data used related to information on slope, soil type, geology, land use, and rainfall as a reference, each of which has a role that is interrelated with one another. The result found that, the parametric overlay by GIS that been used produce a description of the analysis that the level of vulnerability to landslides in the Nagari Sungai Pinang, Sungai Nyalo, and Mandeh areas is at the moderate to high level. The landslide susceptibility level starts from very low, low, medium, high, and very high levels, respectively, in the percentages of 1.30%, 6.24%, 42.93%, 41.74%, and 7.80%.</span></p>Aulia Fajrin Ramadhani NasutionDevrina Nur AzizahAnnisa KhairaniRamatul Akbar

https://journals.insparagonsociety.org/index.php/epicentrum/article/view/165
<p><span style="font-weight: 400;">This research is based on the problem of the modules used by lecturers in the Regulatory System course who are still not able to encourage their students to be able to study independently. The material presented by the lecturer in the regulatory system course at the Faculty of Engineering, Padang State University, has not been fully understood by students. This is because the material is not conceptual, and also less interactive. This has an impact on the one-way learning system, where students only expect explanations from the lecturer. This study aims to produce a valid, practical, and effective E-Module Regulatory System. This study uses a 4D model that is defined, designed, developed, and dissemination. While the subjects in this study were students of Electrical Engineering, Padang State University. The research instruments were validity questionnaires, practicality questionnaires, and tests. The results of the study obtained data on the validity of the E-Module from material experts and media experts with valid categories. Based on the practicality test with the lecturer and student respondents, it was found that the E-Module Learning System Management was in the very practical category. Testing the effectiveness of the E-Module Learning Management System through the students' post-test results, it was found that the E-module was categorized as effective.</span></p>Elsa Cipto RianiAdi ThohaSyukriNadatul Nazhifah DionaYoga EdlinoTio Martias Riani

https://journals.insparagonsociety.org/index.php/epicentrum/article/view/262
<p>This study aims to analyze the traditional roof of Minangkabau houses to determine their potential in reducing carbon emissions on the ozone layer. The analysis is conducted by examining the materials and construction techniques used in the traditional roof, as well as their impact on the environment. The results show that the use of natural materials such as wood, bamboo, and thatch in the construction of Minangkabau house roofs can contribute to the reduction of carbon emissions. Additionally, the unique shape of the roof, which resembles the horns of a water buffalo, provides natural ventilation and lighting, reducing the need for electricity.</p>Salsabila RahmiRihadatul AisyaMytha Amelya
