Abstract

Peranan gas LPG pada saat ini sangatlah penting bagi kehidupan manusia baik di rumah tangga maupun di industri. Namun, gas dapat berdampak negatif, terutama bila tidak diketahui telah terjadi kebocoran dari tabung atau tempat penyimpanan gas LPG tersebut. Penyebab dari bocor tabung gas ini bisa terjadi karena kebocoran pada selang, tabung atau pada regulatornya yang tidak terpasang dengan baik dan tabung gas yang didistribusikan memang kualitasnya kurang baik ataurusak fisik. Penelitian ini bertujuan untuk menghasilkan sebuah rancang bangun alat pendeteksi kebocoran tabung gas LPG dengan menggunakan sensor MQ-5 sebagai sensor gas, dan ethernet shield sebagai modul pada mikrokontroler arduino uno untuk menghubungkan arduino dengan Berbasis SMS. Cara kerja alat ini yaitu, ketika sensor MQ-5 mendeteksi gas LPG maka sensorakan mengirimkan data ke mikrokontroler pada arduino untuk diberikan respon berupa menyalakan, buzzer sebagai alarm, dan alat ini dapat mengirimkan informasi data analog gas ke smartphone android menggunakan plaltform Cayenne melalui Perangkat SMS.

Abstract

One of the factors for the low mathematical understanding of students is the inappropriate learning method. The selection of the STAD method is believed to be able to improve students' mathematical understanding. This research uses a quantitative approach (pre-experiment). This study aims to determine the difference in students' mathematical understanding before and after using the STAD method. The research population consisted of STIKOM Tunas Bangsa students majoring in Information Systems in the 2023-2024 academic year, with 8 classes, and the sample was drawn from class 23S01. Quantitative data analysis using SPSS 25, namely paired sample t-test. The results showed that the correlation value was 0.714, indicating a strong and significant correlation between initial understanding and final understanding. Based on the mean value of initial understanding (pretest) with a value of 70.83, lower than the mean final understanding (Post-test) after using the STAD method of 79.44. The sig. A value of 0.00 or smaller than 0.05 states that mathematical understanding after using the STAD method is higher than before using the STAD method. Thus, it can be concluded that there is a significant and strong increase in mathematical understanding after using the STAD-type cooperative method in higher education, one of which is for STIKOM Tunas Bangsa students
