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.

The application of organic agriculture in lowland rice farming is one of the interesting topics in an effort to reduce environmental pollution caused by the use of chemical fertilizers and pesticides. This study aimed to determine the level of production and analyze the environmental impact of the soil from the application of organic and conventional agriculture in the Banyan District, Deli Serdang Regency. The results showed that 1) There was a significant difference between the production of harvested dry grain (GKP) of organic paddy and the production of harvested dry grain (GKP) of conventional lowland rice. 2) The level of soil fertility in organic and conventional lowland rice farming has low criteria

Produksi dan Fisiologi Kedelai pada Kondisi Cekaman Kekeringan dengan Aplikasi Bradyrhizobium japonicum yang Diberi Penginduksi Genistein Hasanah, Yaya; Rahmawati, Nini

ABSTRACTMutualism symbiosis between B. japonicum and soybean root is a complex case and managed by molecular signal exchange. Genistein is one of the main isoflavones in soybean root exudates which is responsive to nod gen induction in B. japonicum. Drought stress could give negative effect on the symbiosis. The aim of the research was to study the role of B. japonicum induced by genistein on production and physiological characters of soybean under drought stress. The experiment was conducted in a green house, Faculty of Agriculture, University of Sumatera Utara, using a randomized complete block design with three factors. The first factor was genistein induction, consisted of with and without genistein. The second factor was B. japonicum inoculation consisted of without B. japonicum, isolate 1, isolate 2 and isolate 3. The third factor was soil water content condition, consisted of 40%, 60% and 80% of field capacity. The parameters observed were shoot dry weight, root dry weight, net assimilation rate, dry weight per plant, 50 seeds weight and proline content. The result showed that increasing drought stress conditions decreased shoot dry weight, root dry weight, net assimilation rate, effective nodules number, seeds dry weight per plant and 50 seeds weight. The result showed that as an inducer of B. japonicum in drought stress condition, genistein reduced the effects of water stress on root nodulation of soybean. Proline acts as osmoregulator for increasing tolerance to drought stress in plants.Keywords: drought, genistein, soybean, root nodulation

One of the cassava-producing districts in the highlands topography is Toba Regency. Cassava plantation centres spread across Toba Regency are located in Laguboti District. Cassava land is starting to be displaced due to a lack of land management and processing. This study aims to enable the community to maximize the growth of cassava-based on different genotypes and land use according to soil characteristics so as to increase the production of cassava as a food crop in Toba Regency, North Sumatra, Indonesia. The method is the determination of land units, observations of morphological characteristics of cassava, observations of land characteristics, and the collection and analysis of soil samples on cassava fields carried out in the laboratory. The results were 7 types of cassava diversity in Toba Regency with different morphological characters, namely Malaysia (G1), Siroti (G2), Simerah (G3), Sumedang (G4), Siputih (G5), Adira (G6) and UJ5. (G7). The distribution of pH and nutrient content in each cassava field with different genotypes in Laguboti District, Toba Regency is very varied. pH ranged from acid-neutral, Nitrogen ranged from 0.17% – 0.63%, Phosphorus ranged from 0.05% – 0.24%, and Potassium ranged from 0.04% – 0.27%. The altitude of the place ranges from 920-940 m asl.
