Abstract

The goal of this exploration is to fabricate an estimating instrument for perceiving Methane, Smelling salts, and Carbon Dioxide gas concentrations in cow feces within a confined space. The feasibility of gas concentration detection devices using MQ-2 sensors, MQ-4 sensors, and Arduino Uno-based MQ-135 sensors will also be tested. This research relates to physics, particularly instrument physics. The research will employ hardware design, software design, and testing methodologies. The gas used for testing was produced from 500 grams of cow feces through three treatments: no treatment, addition of 50 grams of activated charcoal, and addition of 50 milliliters of EM4. The tool validation test was conducted by three experts, and the typical worth acquired was 95.8%, classified as entirely achievable. The experiment yielded the highest concentrations of CH4, NH3, and CO2 gases at 11:30 AM (plus EM4), 03:00 AM (plus EM4), and 24:00 AM (without treatment), respectively, with readings of 9.49 ppm, 26.89 ppm, and 4.57 ppm.

Abstract

The purpose of this research is to increase the entrepreneurial spirit of students by utilizing social media in marketing strategies for Cassava Chips products. This study uses qualitative research methods with data collection techniques, namely observation, interviews, documentation, and questionnaires. This research was conducted on March 21, 2023, at Bengkulu University. The population and samples taken from this study were physics education students class of 2020. For the population, there were 51 students, while the samples were taken, namely 10 physics education students class of 2020. Observations were made when making observations while the questionnaire contained responses to Cassava Chips products. carried out by students as respondents. The results of this study indicate that the consumed cassava chips are very good and worth selling. The results of the study also stated that utilizing social media in marketing cassava chip products could improve the entrepreneurial spirit of Physics Education students for the better.
