Reverse Engineenering Pola Bodi Pompa Hydrant : Analisa Pengecoran Dan Proses Finishing Dengan Cetakan Pasir Semen Proses Menggunakan Material Aluminium Silikon (Al Si)
This research aims to reverse engineer the body pattern of a hydrant pump using sand-cement molds and aluminum (Al) material. It investigates the effect of the casting process on the mechanical properties of the resulting hydrant pump body pattern, as well as the extent to which the machining process performed after casting influences the final quality of the hydrant pump body pattern made from aluminum material. The casting results showed defects such as trapped gas and rough surfaces, which were improved through machining processes, including smoothing, filling, and painting. Tensile testing (ASTM E8) yielded a maximum load of 101.538 MPa and a strain of 3.25%, in accordance with the standards of 90 MPa and a strain of 3–5%. Impact testing (ASTM E23) indicated a value of 0.3625 J/mm², compared to the standard of 0.1179 J/mm², signifying good material toughness. Chemical composition testing (ASTM E415) revealed an aluminum content of 85.08% and silicon content of 9.545%, which enhances the material's strength. The aluminum material is classified as number 4030. Based on the measurement results, it is concluded that the mold pattern design should be made larger to anticipate machining, as the machining percentage is high for the hydrant pump body pattern measuring 430.50 mm, while the product volume is 422.40 mm. The average machining percentage for the cast hydrant body is 1.50% of the hydrant body pattern design

Sistem Monitoring Kualitas Udara Ruangan Berbasis IoT Dengan Peringatan Real-Time Melalui Notifikasi Telegram
Indoor air quality is an important factor that can influence human health and comfort, especially in urban environments and industrial areas which often experience a decline in air quality. In addition, unconscious human activities indoors, such as the use of fuel-burning equipment or chemical products, also have the potential to worsen air quality. Therefore, we need a system that is able to monitor air quality and provide real-time warnings. This research aims to develop an Internet of Things (IoT) based air quality monitoring system that can provide real-time notifications via the Telegram application. This system is designed to detect dangerous gases such as carbon dioxide (CO2), carbon monoxide (CO), LPG gas leaks, and measure room temperature and humidity. This system uses the MQ-135 sensor to detect CO2 gas, the MQ-7 sensor for CO, the MQ-2 sensor for LPG gas leaks, and the DHT22 sensor for temperature and humidity. The ESP32 microcontroller is used as a control center that sends sensor data to telegram. Buzzers and LED lights are used as indicators of air pollution directly on site. Real-time alerts are sent via telegram when gas levels or temperatures exceed preset thresholds, allowing users to take immediate action. The research results show that the system is successful in detecting air pollution and monitoring environmental conditions in real-time. In testing with the MQ-2 sensor, the LPG gas concentration was recorded at 7080 PPM at a distance of 1 cm, activating the red LED and sending a warning notification via Telegram, indicating dangerous air quality. These alerts allow users to immediately respond to detected air quality problems
