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

Daya dukung tanah sangat penting dalam sebuah perencanaan stuktur pondasi bangunan, biaya penelitian tanah yang mahal menjadi penyebab tingginya biaya perencanaan. Oleh karena itu perlu solusi untuk mendapatkan nilai daya dukung tanah yang sesuai dengan kondisi sebenarnya. Penggunaan data tanah khususnya dari Cone Penetration Test (CPT), memainkan peran penting dalam analisis daya dukung untuk mencegah kegagalan fondasi tiang pancang. Analisis daya dukung dari data CPT telah banyak dikembangkan untuk memprediksi kapasitas aksial tiang dan juga mendapatkan jenis tanahnya (Shahin et al., 2010). Hubungan antara tahanan ujung, gesekan samping, dan sifat tanah yang diperoleh dari uji CPT sangat penting untuk merancang fondasi tiang (Wu et al., 2018). Selain itu, korelasi data CPT dengan kapasitas tiang telah menunjukkan hasil yang memuaskan karena informasi sifat tanah yang dapat digunakan sebagai tambahan informasi (Alkroosh & Nikraz, 2011). GIS terbukti lebih efisien dalam mengolah data dalam jumlah besar dan memberikan hasil yang lebih reliabel (Qader et al., 2023). Teknik ini memungkinkan analisis data yang lebih cepat dan akurat. GIS membantu dalam pemahaman yang lebih baik tentang struktur bawah tanah dan mendukung keputusan yang lebih informatif dalam perencanaan pembangunan dan disarankan agar penggunaan GIS diperluas untuk analisis geoteknik yang lebih komprehensif.

Abstract

This study aims to overcome the lack of weather monitoring tools in Indonesia. The main factors of extreme weather changes in Indonesia are the rainy season and strong atmospheric dynamics. Weather monitoring tools developed based on IoT, allowing monitoring remotely. The research method used the ADDIE model, with data collected through validation tools and analyzed qualitatively using the Likert scale. Validation by three experts showed an average result of 89.29%, which falls into the very decent category. This tool aims to provide solutions for coastal communities in the city of Bengkulu, allowing them to get early warnings about weather changes, especially strong winds. This tool has been proven to fit its design and works well. Recommendations for future research are the addition of regional classification, replacement of more durable sensors such as other types of DHT sensors, and the addition of data loggers to store previous measurement history.

Abstract

Geographically, Indonesia is located in three rings of active plates and surrounded by various active mountains that make Indonesia prone to earthquakes. When the earthquake occurred, there were still many people who were late in getting information to carry out the early evacuation process. This research aims to provide solutions to people who are late in receiving earthquake information by developing a microcontroller-based earthquake early warning system alarm with MPU6050 accelerometer sensors and NodeMCU ESP8266 to minimize possible losses. This research uses the Research and Development method with the ADDIE development model, to develop an Arduino uno-based earthquake alarm from previous research. This research uses a literature study system for analysis of earthquake problems when an earthquake occurs. The results of this study are in the form of a tool equipped with an Arduino Uno microcontroller system, where the earthquake warning system is run according to the system design. The tools developed were validated by three expert lecturers using validation questionnaires. Data analysis was carried out quantitatively to determine the feasibility of Arduino-based earthquake early warning tools using the Likert scale. Based on the average results of validation tests by experts, 91% of earthquake early warning tools developed are in the very decent category. Based on the trials carried out, the tool can provide warnings to the public directly
