<![CDATA[Chrysanthemum is one of the most important flowers and has the highest consumption in the world. Apart from being used as ornamental flowers and cut flowers, several types of chrysanthemum are used as herbal plants, with their anti-microbial and anti-fungal properties, chrysanthemum plants are developed as a cure for tumors and cancer. One of the locations of chrysanthemum farming in East Java is Tutur District, Pasuruan Regency. Located at an altitude of 400 - 1,600 meters above sea level (masl), chrysanthemum cultivation in Tutur District is carried out by farmers who are members of the Agro Mitra Cooperative. In this community service program, several new problems were found from farmers who have used PLTS technology in greenhouses. The connection of an inductive load in the form of a water pump in a solar panel installation that uses a modified sine wave inverter causes the water pump and inverter to burn due to bad harmonic effects, so that the inverter will be replaced from the modified sine wave type to a pure sine wave inverter. The results of the activities that have been carried out are the assembly and installation of a pure sine wave inverter on a 1,400 Watt PLTS which is used to supply electricity to lighting for chrysanthemum plants and the irrigation process at Partners. Check the feasibility of greenhouse electrical installations. In addition, counseling and training on how to care for solar panels was also carried out. It is hoped that with this community service activity (abdimas), the provision of electricity from solar energy can help farmers improve the process of cultivating chrysanthemums because electrical energy will continue to be available. The application of pure sine wave inverters works better in handling various types of greenhouse loads, especially inductive loads. Besides that, with the pure sine wave inverter system, farmers do not need to worry if the PLTS system must be used to turn on the water pump for irrigation purposes.]]>
