Abstract

In modern society, electricity is essential for both daily life and industrial operations. Frequent power outages in Indonesia frequently cause disruptions to household, office, and industrial operations, especially during periods of high demand. As a solution, generator sets (gensets) are commonly used as backup power sources. However, manual checks are still used in many installations for monitoring and switching between PLN (State Electricity Company) and genset sources, which can raise operational risks and delay response times. While switching is addressed by existing systems like Automatic Transfer Switches (ATS), they typically do not include real-time notifications or integrated remote monitoring. Using an ESP32 microcontroller and PZEM-004T voltage sensors, along with the Telegram Bot API, this study suggests designing and implementing a real-time voltage monitoring system. The system finds the active source, measures voltage from PLN and genset sources, and instantly alerts users via Telegram. In comparison to a calibrated multimeter, performance testing reveals an average notification delay of less than 5 seconds and a voltage reading error margin of less than ±2%. By offering an affordable, scalable, and interactive monitoring solution, the developed system fills in the gaps in earlier research. It improves responsiveness and dependability in settings that need constant electrical monitoring by giving users access to real-time updates on voltage levels and power source status.

Abstract

Salah satu jenis baja yang paling banyak digunakan adalah baja 42 atau baja karbon rendah yang dibuat dan dibentuk menjadi komponen, sparepart, atau alat-alat sesuai dengan kebutuhan didunia industri. Tujuan penelitian ini adalah untuk mengetahui analisis kekuatan tarik pengaruh perlakuan panas hasil pengelasan kampuh V baja 42 dengan media pendingin air dan oli. Pada penelitian ini material dibentuk menjadi kampuh V. Kemudian material dibentuk menjadi spesimen uji tarik ASTM E8M- 04 tipe 01,pada proses heat treatment dengan variasi temperature 00C sampai 2000C, 4000C, 6000C, 8000C, 10000C, masing- masing spesimen dilakukan quenching pada media air mineral dan oli SAE 10, selanjutnya material dilakukan pengujian tarik untuk mengetahui nilia kekuatan material. Berdasarkan penelitian tersebut diperoleh nilai kekuatan tarik paling tinggi media pendingin air mineral pada temperature 6000 dengan nilai 33.999 N/mm2 dan nilai kekuatan Tarik paling rendah pada temperature 10000 dengan nilai 30.388 N/mm2, kemudian nilai kekuatan tarik paling tinggi media pendingin oli SAE 10 pada temperature 6000C dengan nilai 34.589 N/mm2 dan nilai kekuatan tarik paling rendah temperature 10000C dengan nilai 29 N/mm2. Dari hasil penelitian tersebut dapat disimpulkan bahwa analisis kekuatan tarik baja St 42 yang paling tinggi berada pada temepratur 6000 C media pendingin oli dengan nilai 34,589 N/mm2 dan nilai kekuatan tarik paling rendah berada pada temperatur 100o0 C media pendingin oli dengan nilai 29,479 N/mm2, adapun media pendingin yang baik digunakan setelah proses heat treatment pada material baja St 42 adalah oli (SEA 10).
