Water turbine is a tool to convert the potential energy of water into mechanical energy, this mechanical energy is then converted into electrical energy by a generator. Crossflow turbines are radial, small pressurized turbines with tangential injection from fan rotation with a horizontal shaft. The flow of water flows through the pipe entrance, and is arranged by a propeller and into the turbine fan rotation. After the water passes through the turbine fan rotation, the water is at the opposite fan rotation, thus providing additional efficiency. Finally, water flows from the casing either freely or through a tube under the turbine so that it rotates and turns the generator so it can produce electricity. Maintenance of PLTMH is carried out namely preventive maintenance such as; cleaning, lubrication and periodic checks. Maintenance corrections are carried out with the aim of being able to maintain the PLTMH component. Predictive maintenance of a treatment carried out in accordance with the conditions of the PLTMH and predicting damage that will occur in PLTMH

Training and socialization of Occupational Safety and Health at PT. PLN (Persero) Teluk Sirih Generation Implementation Unit UIK SBS Bungus Padang District is a community service from the PKM PNP team. This training aims to provide education to employees of PT. PLN (Persero) Teluk Sirih Generation Implementation Unit, UIK SBS, Bungus District to always use occupational safety and health (K3) in the implementation of work. In the field there are still many workers or employees who do not heed the rules of work safety, such as not using safety shoes, helmets, gloves when needed, masks when needed, and even working at a height above 2 (two) meters must use a Body Harness.

K3 culture must be applied properly to maintain work stability in the field by providing education through training and socialization of Occupational Safety and Health at PT. PLN (Persero) Teluk Sirih Generation Implementation Unit UIK SBS Bungus Padang District is expected to provide a clear understanding and good education on the understanding of K3 in the industrial world, especially PT. PLN. The method applied to this service provides training and socialization to staff, employees and stake holders of PT. PLN and aims to familiarize the 5S Work Attitude culture, as we know Seiri, Seiton, Seiso, Sheiketsu and Shitsuke. This training helped increase the understanding and awareness of the workforce of PT. PLN (Persero) Teluk Sirih Generation Implementation Unit UIK SBS on K3 culture and the use of personal protective equipment (PPE) for workers when doing work. It is hoped that later when the participants work, they will apply K3 to avoid work accidents.
