Abstract

The learning methods in Vocational High Schools (SMK) have undergone significant changes. These changes were made because the education system needs to adapt to the conditions of society during the COVID-19 pandemic. SMKN 8 Bandung has implemented a blended learning system with 50% offline and 50% online learning. To maximize the teaching and learning process, the school has developed a Webmoodle application to aid student learning. This research aims to determine students' responses to using e-class and WhatsApp as learning media and to assess the improvement in student learning outcomes through the implementation of Webmoodle-based learning media. This study uses a quantitative approach with a quasi-experimental method, employing a nonequivalent control group design with pre-test and post-test. The results of this study show that e-class learning media is superior to WhatsApp. Nonetheless, both e-class and WhatsApp can effectively enhance student learning outcomes.

Abstract

This research aims to address public concerns regarding the use of hydrocarbon refrigerants, which are prone to leakage and have the potential to cause explosions and fires. Therefore, a hydrocarbon refrigerant gas leak detector was developed using the MQ-2 sensor for accurate detection. This device utilizes an Arduino Nano microcontroller to detect the gas. The manufacturing method includes both hardware and software development. The results show that this device is effective in detecting leaks by measuring the PPM (parts per million) values from five sensors, producing 70 buzzer sounds in 20 minutes when 105 grams of hydrocarbon refrigerant is released, and the device tsemperature reaches 30°C. The visual indicator provides "safe" and "leak" statuses at a pressure of 130 Psi, and the light indicator remains on during testing. In conclusion, this device improves the maintenance procedures of hydrocarbon refrigerants in refrigeration systems, giving users peace of mind because leaks can be detected with sound and visual indicators every 17 seconds.
