Abstract

Maintenance of distribution substations is a mandatory activity to minimize damage to electrical equipment. The state electricity company (PLN) of Ciputat's customer service implementing unit (UP3) as the executor is currently carrying out preventive maintenance with the total blackout method, this causes electricity distribution to consumers to be cut off. As a result, PLN suffers losses in terms of achieving the system average interruption duration index (SAIDI). So, we need a zero-downtime maintenance method in order to improve the maintenance of concrete type distribution substations without turning off the electricity supply to consumers and suppressing the SAIDI value of maintenance. Maintenance observation methods, trials, SAIDI values from the results of maintenance are used as references and assumptions for the maintenance plan of distribution substations for the following year. The zero-downtime maintenance method was successfully applied to the CP227 substation without going out on the consumer side, resulting in a maintenance SAIDI value of 0 (zero) minutes per customer and successfully reducing the duration of outages during maintenance by 100%. The total SAIDI value is 56.04 minutes per customer per year from the maximum SAIDI limit for maintaining PLN UP3 Ciputat which is 81.5 minutes per customer per year.

Abstract

Palm oil mill processing companies in their operations use Water Tube Boilers which are fueled by shells and fiber. Boiler or Steam Kettle is a container that contains water or other fluids to be heated. Boiler with a capacity of 30 tons. In general, every machine produced by the factory is always equipped with a handbook/instruction book on how to install, maintain and operate it. Likewise with the boilers in the Company there are manuals regarding specifications for operation, maintenance, installation, and others. of various kinds of boiler fuel mixtures for combustion can produce different thermic efficiencies depending on the percentage of the mixture, in this study the results of laboratory tests obtained the calorific value of the fuel mixture of 70% fiber and 30% shells had the highest calorific value, namely 4604.7 Cal /g. The highest boiler efficiency value produced was 53.9% using 100% shell fuel, the efficiency using 100% fiber fuel was 51% and the lowest boiler efficiency value produced was 49.5% using a mixed fuel of 70% fiber and 30 % shell.

Abstract

The distance to an object can be known without having to measure it with a meter. The design of this tool can determine an object with a certain position in the form of an indicator that is displayed automatically. An object is a part of determining indicators that can be used as receiving media for the final boundary reflection. With this tool, you can accurately determine the distance to objects without using conventional measuring instruments. The method used is to design the equipment and then test the tool. This tool works when there is input in the form of a password code via the keypad, and if the code or password is entered correctly, the microcontroller will provide high input to the relay to activate this solenoid which is run with the Arduino IDE software so that the microcontroller can detect keypad input properly, the delay is applied to activate the solenoid, by using the proximity sensor we know the accurate limit is for this tool to be able to read the distance of the object provided that the closest distance to the object is 0.5 meters and the farthest is 2 meters with a response time interval of 0.07 seconds to 2.10 seconds, this equipment controlled by Arduino with a listing program that has been set to read objects at a certain distance, with a reading distance. the program listing uses a sound indicator as an output with a sound indicator at a distance of approximately 2 meters.

Abstract

Programmable logic controller (PLC) can be design for various purposes, one of which is to design a fire extinguishing system, by assembling several components of PLC, solenoid, spingkle, power supply, adaptor,smoke detector, heat detector, pilot lamp, push button,relay, selector switch, Design the program setting to detect smoke and high temperetures that occur in the event of a fire. If the smoke detector detect smoke and high temperatures, the sensor will give a signal to the plc to turn on and activate all working components and extinguish the fire. . In the future, the use of this tool can be installed in lecture rooms in Unbari, especially the Faculty of Engineering room and developed for the use of Human Interface which is directly connected to firefighters.

Abstract

This study aims to plan a solar power plant with an off grid system that will be used for electricity needs in Hamlet Kunangan Jaya 2 RT.28 which is one of the Hamllet in Bungku Village. Bungku Village is included in the 3T area, which is left behind, foremost, and outermost.Hamle Kunangan Jaya 2 RT.28have not enjoyed electricity from PLN due to difficult access and far from urban areas.The research was conducted with a descriptive research method. The selection of this type of method is used on the basis of the consideration that the nature of the research describes a plan carried out to meet the electricity needs of public facilities. Studies field were carried out to determine the electricity needs of public facilities: Mosques, Polides, and Elementary Schools, find out the number of panels needed, measure solar radiation and measure the area of the building. Calculation of electricity requirements is carried out in order to find out how much electricity is needed in public facilities, carry out design plans and calculate a budget plan to describe the planned installation. The results of solar data measurement for Optimal Global Irradiation in Bungku Village are 4,549kWh/m2 per day, the required amount of solar cell power is 6,000WP, three 40A Solar Charger Controllers, 2,800Ah batteries and 8000Watt Inverters. The total load required for mosques, polides, and elementary schools is 25,126Wh. The total RAB for PLTS development using an off-grid system requires a cost of IDR 138,647,000.

Abstract

The learning system in vocational education is more directed to practical learning. Therefore, learning media is needed that can make students learn interactively and independently. The research aims to create an industrial automation system learning media as a learning medium for industrial automation courses. The learning media is in the form of a programmable logic controller (PLC) trainer equipped with sensors and combined with a human machine interface (HMI). PLC trainer is made because PLC devices are widely used in industrial automation systems. The PLC component has not been equipped with a display, therefore in this study PLC is combined with HMI. HMI is an interface that connects machines with humans. The Outsel PLC was chosen because the price is very affordable and developed by domestic developers. Trainers are made in a compact form, and easy to carry anywhere. Several simulations were carried out to test the function of the trainer. The test results of the PLC trainer show that the PLC trainer is able to control the process according to the logic programmed, and the HMI is able to display the ongoing process, thereby increasing the interaction between machines and humans.
