The problem faced is the decline in the performance of a 650 liter/minute centrifugal pump due to wear on components, especially the impeller, rolling bearings, and mechanical seals in supplying process water and clean water in industrial production systems. The planning objective is to obtain a maintenance schedule for a 650 liter/minute centrifugal pump for the operational period of 2026 and the ratio between maintenance costs and profits generated by the machine. The maintenance planning method includes collecting maintenance data from previous maintenance periods, reviewing centrifugal pump specifications, applying the inspection, replace, repair, and overhaul (IRRO) approach, estimating the age and price of components that are expected to be damaged, estimating the cost and duration of dismantling and installing components that have been repaired in accordance with the provisions of the requirements for usable components or replacement parts, scheduling maintenance and repairs, estimating maintenance and repair costs for the 2026 period, and determining the ratio of maintenance costs to profits. The planning results are in the form of a maintenance schedule for the 2026 period worth IDR 4,290,000,-, a maintenance cost to profit ratio of 7.44% and the implications indicate that the machine is still suitable for use and prospective for operations in the next few years.  

In a steam power plant, of course, it has a very important prime mover, namely an electric motor, but electric motors are used in a variety of functions, one of the main roles in this electric motor is as a condensate extraction pump in a steam power plant which functions to push materials for power plant production. Steam power, namely sea water, goes to the generator to become a power plant. The method used is qualitative by using observation techniques, interviews and literature studies. This condensate extraction pump (CEP) electric motor can be operated automatically and manually for routine maintenance and good inspection results.    

The need for water consumption is currently very high, almost all human activities require water, therefore the process and production of water is very important to maintain health, the electric motor is the main driving tool needed in the process of cleaning water, therefore the motor is able to move the machine to clean the place water filter or water filter at the Tirta Madani Regional Drinking Water Company in Serang City to maintain water quality. The method used is qualitative by using observation techniques, interviews and literature studies. The filter backwash system is one of the ways to care and maintain the quality of drinking water. Backwashing requires an electric motor, a centrifugal pump and an air blower as its propulsion device.
