The spesies composition of arthropods on agro-ecosystem can be seen as a general indicator for ecosystem stability and ecological resilience. Agricultural intensification has been linked with losses of biodiversity and disruption of key ecosystem services in farmed landscapes. This study aimed to determine how cropping system and farming systems able to increase the diversity of insects on potato field, that can be used as an integrated pest management strategy. The result showed that insect diversity index and population of natural enemies in polyculture cropping system is higher than monoculture cropping system, while the pest population is lower. Insect diversity index and population of natural enemies in organic farming systems is higher than conventional farming systems, in general the pest population was lower in conventional farming systems, but not significant with organic farming system. The polyculture cropping potatoes+cabbage+mustard+celery, potatoes+cabbage, potato+mustard respectively which grown by organic farming systems provide the highest insect diversity index, the lowest percentage of crop damage, the lowest populations of pest, and the highest natural enemy populations when compared with the same polyculture cropping with conventional farming systems.Â Keywords: Cropping system; farming system; insect diversity; potato

Research-based community partnership program activities involve two partners, namely the Murti Lestari Farmer Group and Agrina Creation UKM in Helvetia Village, XI Gang Sawit Hamlet, Labuhan Deli District Deli Serdang Regency. This dedication activity is the application of the results of research that had been carried out two years earlier which was USU's Talent Grants in 2017 and 2018. The problem faced was the lack of understanding of oyster mushroom baglog waste management techniques that have the potential to pollute the environment, on the other hand the farmer group Murti Lestari also experienced difficulties in increasing the quantity and quality of sweet potato production which is also widely cultivated in this village. The low interest of farmers is also encouraged because of the low price of sweet potato products and a relatively limited shelf life. The method implemented for training and discussion, accompanied by the practice of making compost from mushroom baglog waste, the practice of preparing planting material in the form of local sweet potato clones with high beta carotene content, compost application in sweet potato cultivation, maintenance to harvesting and post-harvest process using processing equipment into sweet potato flour rich in beta carotene and various other processed food products. Activities that have been carried out are training on composting of baglog mushroom waste using compost counting machines and bioactivators introduced in this activity so that the composting process goes faster, training on technical culture of orange sweet potato cultivation by applying mushroom baglog compost, training on mushroom making mushrooms and composting Oyster mushroom cultivation using shelves made of mild steel and fogging using a sprayer. Production and quality of yields of sweet potatoes that were given compost baglog oyster mushroom waste increased compared without the provision of compost. The next crop is processed into sweet potato flour with high beta carotene content and various food products using an introduced machine, which is a sweet potato slicing machine, flour machine, macaroni making machine and equipment for making sweet potato flour based food processing products.

Regemuk Village has the potential to be developed into a new tourist destination village. The village which is located along the coastline of Deli Serdang Regency is geographically the closest village to Medan City and the location is adjacent to Kuala Namu Airport. One of the advantages of this village is the presence of a stretch of mangrove forest which is still quite good along the 7 km coastline. The development of the village into one of the beach tourism destinations has been a long-term discourse, but until now it has not been implemented. To realize this, it is necessary to explore the development of supporting facilities in order to initiate the development of the village into a tourist destination mangrove tourism area. Seeing this reality, the USU PPM Implementation Team through the Professor Serves Program Scheme helped community problems by developing mangrove forest areas and providing supporting facilities, namely beach tourism park umbrellas. The existence of this facility is expected to help increase the carrying capacity of this newly formed tourist site. This program will encourage the spirit of the realization of mangrove tourism areas and be able to produce other downstream tourism products.

Deli Serdang District is one of the regions producing red guava fruit in Sumatra Utara. Cultivation of fruit trees is never separated from pest disorders, which can cause a decrease in the quality and quantity of fruit. Then proper control is needed so that it can maintain the balance of insect populations in the field. This study aims to determine the type of parasitoid and parasitoid parasitic levels in red guava crops. Identification morphology of parasitoidâ€™s fruit flies rearing from red guava fruit that had been attacked by fruit flies was taken from several locations of red guava crops in Deli Serdang District. Two species of parasitoid Psytalia sp. the parasitic fruit fly in the red guava crop. Â The parasitoids that have been found then identified at LIPI, Cibinong, Bogor morphologically has many similarities with Psytalia walker and Psytalia walkeri so that identification of species is only made close to the morphology of the species. Only in two locations were found parasitoidâ€™s rearing from infected fruit, namely Parasitization rate of 6.9% in Sei Beras Sekata village, and Kolam village of 3.6%.
