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.

Sumberdem Village in Wonosari Subdistrict, Malang Regency, has agricultural products in the form of medicinal plants, one example is African leaves. This plant is used as a tea product for consumption by diabetics. SMKN 1 Wonosari is a partner that produces African leaf tea. To make African leaf tea products, use a dryer. The drying machine owned by SMKN 1 Wonosari was not optimal due to several problems when we used it. There were 3 problems when the team used the partner's dryer, namely the location of the heating element was not optimal so that the drying of the African leaves was not evenly distributed, the sharp edges of the racks could cause work accidents and the wheels on the drying mat were not strong enough to withstand the load. The solution to the problem used is repairing the dryer. There are 3 methods in community service activities carried out to achieve the outcome, namely the approach method, the reverse engineering method and on the job training. The result of this activity is an African leaf drying machine using a heating element on each shelf. This drying machine with 1450 watts of power has the advantage that the results of drying African leaves can be evenly distributed, drying time is faster and safer to use. The use of this drying machine partners can save production costs of Rp. 7,403 for every 4kg of wet African leaves.

Refrigerant that is released into the environment will damage nature because of the chlorine. In addition, refrigerant is also a toxic substance and will damage the central nervous system and cause negative cardiovascular effects. To reduce the release of refrigerant into the environment, in this technical guidance, AC and refrigerator technicians were chosen as partners. AC and Refrigerator technicians are people who direct contact with the refrigerant. Offline Technical Guidance was carried out in the workplace by following strict health protocols during the covid 19 pandemic. For the provision of materials that do not use equipment, technicians were given via zoom meeting to reach all technicians at once. From the result of questionnaires , it was found that AC and refrigerator technicians have a good understanding of the effect of refrigerant on the environment, the effect on humans or the technicians themselves, the history of refrigerant, handling used refrigerant and safety and health at work.

Abstrak - Usaha olahan yang menjadi khas Kediri adalah sambel kacang atau sering dikenal dengan sambel pecel yang mempunyai rasa gurih dan pedas. Mitra dari pengabdian masyarakat ini adalah usaha sambel kacang milik Ibu Erni yang didirikan tahun 1998. Proses pengolahannya adalah yang pertama menyangrai kacang sampai matang, kemudian mengiling bersama bumbu dan mengemasnya. Dalam proses penggilingan kacang diperlukan jarak yang lumayan jauh karena harus menggiling ke pasar. Dan di penggilingan juga beresiko untuk tercampur dengan sisa gilingan dari penggilingan yang sebelumhya, sehingga bisa mempengaruhi rasa dan kehigienisan sambel kacang tersebut. Asalah mitra adalah: 1. Aspek produksi (permasalahan menyangrai, penggilingan dan pengemasan); 2. Aspek pemasaran.

Roads are the main means of transportation in everyday life. Transportation is divided into 3 parts, namely land, sea and air transportation. People really need facilities in transportation, because transportation will make it easier to increase people's income and can improve the economy in an area, both by the community itself and can increase income for a village. In the village of Pataan, Lamongan Regency, there is a temple that is a relic of King Airlangga. To get to the temple, residents or the community, as well as people from outside the city have to walk and the road is very up and down. The road during the rainy season will be very difficult to pass. So it takes road planning to build a road. The concrete road is the road to get to the temple location, because with the moving soil conditions in Lamongan, a road with the type or model of a concrete road is needed. Planning Concrete roads must be planned DED, and RAB first.
