Abstract

Communication between the two is done using a handy talky. Communication between langsir officers and train travel organizers is one of the most influential communications in train operations. In (PM No. 45 of 2018) concerning the technical requirements of railway telecommunications equipment, it is stated that at least lansiran communication meets the operating system requirements, every conversation must be recorded. There is currently no recording device for alert communication at Tegal station, while the alert process at Tegal station occurs at least 8 times a day.In this study, an application was made to record the voice of the langsiran communication to record all communications made by the langsir officer and the train travel controller. By taking voice data from the handy talky which is used as a master, then it is connected using a series of interfaces via a cable jack on a PC that has installed a voice recording application for langsiran communication that has been made with Microsoft Visual Studio. The recorded data that has been obtained is processed and stored in a MySQL database with the phpMyAdmin interface.From the test results, the designed software can be run properly, can automatically record alert communication, the stored data can be searched based on the recording code and recording date, and the recorded recordings can be played back and show the recording time

Abstract

The purpose of this research is to create a device that can track the temperature and vibration of an electric motor. It has two sensors: a thermocouple sensor and a piezoelectric sensor. When the electric motor is operating, the device displays digital data in the form of numbers on the monitor screen wirelessly. This research shows that the electric motor can be effectively monitored remotely. The Blynk app can connect with the unit within 0-200 meters without any obstacles. However, if the unit is blocked by a barrier, the distance that can be covered by the Blynk application is 0-160 meters. The test results show that the average electric motor temperature measured is 31.7°C, and the percentage of error value obtained is -1.01%.

Abstract

A bearing is a part that reduces the friction that builds up between moving parts. The proper type of grease must be considered to provide a long bearing life. This study aims to analyze the differences between Mobilith SHC 100 and Gulf Crown EP 2 greases. This study employed a laboratory test method conducted at PT Petrolab Services with the test parameters of base oil viscosity, dropping point, and worked penetration at 250C. Further, as the supporting data, a comparison of the bearing repairs was executed at Balai Yasa Manggarai using Gulf Crown EP 2 grease in 2018 and Mobilith SHC 100 in 2021. The study results suggested that Mobilith SHC 100 grease offered more advantages in maintaining its characteristic stability compared to Gulf Crown EP 2. Moreover, the bearing repairs at Balai Yasa Manggarai in 2018 and 2021 indicated that Mobilith SHC 100 had fewer bearing repairs and higher maximum mileage than Gulf Crown EP 2.

Abstract

Fires in electrical panels are a common problem experienced when electrical shorts occur. This research was carried out to identify and overcome the electrical panel fire problem. Therefore, the researchers automatically made a fire detection device on electrical panels based on the Internet of Things. This study uses NodeMCU ESP8266 Wifi Module as a microcontroller and DHT11 and MQ-2 as sensors. When a fire is demonstrated, or there is smoke and gas to detect a fire hazard on the electrical panel. In this fire detection device, a test of the DHT11 and MQ-2 sensors is carried out, which will turn on the fire alarm system in the form of a buzzer through the NodeMCU ESP8266 microcontroller command, and the results of the test of the tool will be displayed in a real-time database on the firebase. Testing the fire detection device on the electrical panel automatically uses a match tool and sensor readings to read the presence of a fire in the electrical panel. This measurement difference raises the value of the percentage error in the measurement tool.

Abstract

Technological advances have given us many advantages, electronic devices and new procedures. Technological advances can also have negative side impacts if not used appropriately and correctly. In particular, it covers risks arising from careless use of electricity and accidents in the workplace. The research method used is research and development; data is obtained by carrying out direct observations on the tools when assembled. With this sound-based system for turning on the lights, you will be able to control the turning on and off of the lights just by sound, which means you can find out whether the lights are on or off and will be given information via a 16x2 LCD which has been programmed on the Arduino UNO to detect frequencies. The sound sensor on the system receives sound.
