Abstract

In an effort to meet customer needs on supplying electricity in the industrial era 5.0, it needs to have good services which keep growing up and be innovative. One of them is running a premium service which guarantees better quality of service than that of the regular. This research will discuss all of the obstacles that can disrupt the continuity of electricity supply to the customer with premium services, starting from the disruptions at the supply side until at the installation owned by the customer. From the analysis result, ATS (Automatic Transfer Switch) failed several times on working so that caused a black out at the customer side which it should be avoided. Therefore, it is necessary to make some adjustments on setting and wiring to some problems which may arise so that the potential disruption of the ATS or equipment failure can be suppressed. This research aims to minimize and even eliminate ATS performance failures due to system disturbances by implementing rewiring, adding a permissive interlocking system and adding a PLC with a time delay setting.

Abstract

This analysis will discuss how to handle vibrations in the Turbine Rotor. The measuring instrument used is Vibration Analysis test with Prov. 2140 type which measured amplitude, time and frequency domain of vibration signal. The results obtained in this study, firstly, the measurement vibration of rotor at PT PJB Gresik found the highest amplitude of vibration was 59,6 μm at 3000 rpm. In this condition, the rotor is in very good condition as per standard vibration in ISO 7919-2 stated 80 μm at 3000 rpm. However in the next measurement, there is an dramatically increase of amplitude in each vibration measurement. The top amplitude of vibration reached at 115 μm at 3000 rpm and shown a symtom of damage on the rotor as a result of vibration. In solving the problem this time we use the method Root couse analysis (RCA). The results of this research found that there was a short turn to turn on the rotor windings and the closed slot liner holes that caused electric vibrations and needed to be repaired to eliminate vibration disturbances. After repairing the vibration, it decreased which initially 115 μm to 33.5 μm at 3000 Rpm, it is still on the range of the permitted safe zone of ISO standard 7919−2.

Abstract

The purpose of making this prototype is to make a water level pemantauan tool in the dam using ultrasonic sensors and an IoT system. To support the manufacture of this tool, several other electronic components are used, including the NodeMCU microcontroller, ultrasonic sensors, water pumps, relays, and buzzers. The process of the water level pemantauan system in the IoT-based dam works as a whole. The process begins with filling water from box 1 (analogous to river) to box 2 (analogous to a dam) assisted by a water pump to fill the water box. Then the ultrasonic sensor reads the water distance data from the dam and is sent to the microcontroller and then displayed on ThingSpeak via PC / HP. When box 2 is filled with water and reaches the maximum limit, the buzzer will sound and the relay will turn off the water pump automatically. The test results show that the data obtained is accurate. When the sensor reads the water level capacity data at a distance of 6 cm, the dam capacity will be fully read, the buzzer will sound and turn off the relay automatically then send the information to ThingSpeak. Reading or pemantauan the water level in the dam can be an alternative to control the water level in the dam and facilitate the dam guard.

Abstract

Technological developments continue to develop rapidly until the generation of the Internet of things (IoT). IoT is a collection of objects, in the form of physical devices (hardware / embedded systems) that can exchange information between operators or other devices connected to the system. One of the benefits that can be felt is a smart home or smart home, which is a term used to describe a modern residence, with remote control such as controlling electronic goods. This control is intended for savings in electricity use. By using the ESP32 which functions as a liaison between the device and the internet network so that electronic goods that are available from home can be controlled by using an application installed on the smartphone. Based on tests carried out for the same network with a distance of 20 meters the device is successfully controlled, namely turning on and off the electronic device with a response time of 5s for the fastest time and 40s for the longest time, then for different networks, the control can still be done. So that with this smart home application, electricity costs can be saved.

Abstract

Motor vehicle light boxes require a lamp holder installation process. This study aims to automate the process of installing a lamp holder into a motorized vehicle light box through the design of an air press machine. The machine has 5 (five) process stages, namely installing the lamp box on the jig, installing the lamp holder, pressing the lamp holder, installing the lamp on the holder, taking the lamp box from the jig. The product is pressed automatically through a cylinder press mechanism. Based on the test results, it is known that the machine takes an average of 9 (nine) seconds to install the lamp and lamp holder into the light box. The result of this machine is that the time produced is 3 (three) seconds faster than the previous machine, which takes an average of 12 (twelve) seconds. The use of machines has the potential to increase productivity and workforce efficiency. The machine in this research can be developed to increase the efficiency of the assembly process.

Abstract

Electronic equipment made using old technology or electronic equipment in the entry-level category has not been supported by networking equipment, so for the data communication process, the microcontroller requires interfacing facilities that are in accordance with the electronic equipment used, such as a USB port. With the microcontroller that supports IoT, it allows electronic equipment to communicate over the network. An IoT microcontroller such as the ESP32 is equipped with a WiFi feature but is not equipped with a USB controller feature, while the USB Host max3421e supports the communication process using SPI, so that those two microcontrollers can be used to form an interface using the SPI bus. This interface can be applied to electronic equipment with old technology and entry level electronic equipment for wireless communication. For the needs of making an interface between the ESP32 and max3421e, a software was developed by analyzing the SPI features of the ESP32 and the USB protocol according to the USB device state diagram. The results obtained are the handshake process between systems developed with USB devices in the Low-Speed ​​and Full-Speed ​​categories such as printers, flashdisk, bluetooth mouse and external hard disk, and the device descriptor data of each device tested can be read properly.
