The effort to stop the spread of the Covid-19 virus in the education sector is to implement the Distance Learning system so that the teaching and learning process is carried out online. As the rate of spread of the Covid-19 virus decreases, offline learning or Face-to-face Learning is now starting to be implemented again. The city of Surabaya is one of the regions in Indonesia that has made the transition from online to offline learning. Based on a preliminary survey conducted among students of SMP N 36 Surabaya and SMA N 10 Surabaya, there are several obstacles faced during online and offline learning including the inability of students to manage stress so that learning time is inefficient. Therefore, stress management education activities were carried out while studying for students at SMP N 36 Surabaya and SMA N 10 Surabaya in Facing Distance Learning and Post-Covid-19 Pandemic. This activity was attended by 33 students of SMP N 36 Surabaya and 28 students of SMA N 10 Surabaya. The activity is carried out in several stages, namely, the preparation stage, the implementation stage, and the evaluation stage. Based on the service activities that have been carried out, all students from SMP N 36 Surabaya and SMA N 10 Surabaya participated in stress management education activities while studying until the end of the activity. Students from both schools were able to recognize or identify the symptoms of stress shown by the results of a simple questionnaire

The volume of waste or residual materials arising from human fulfillment increases annually in line with the growth of the human population. The potential of household units to manage organic waste has the potential to minimize food waste and other forms of organic waste. Utilizing organic waste as a raw material for composting is an option for handling organic waste from households. This community service project aims to demonstrate to the community how to make liquid organic fertilizer and raise public awareness of the advantages of managing household waste. Training combined with direct demonstrations via interactive learning covering household waste sorting and composting techniques was performed. This event was attended by 25 community household representatives from Panjunan Village, Sukodono, Sidoarjo. The demonstration method that was used was thought to be effective because the community was interested and came up with new ways to use empty land as a follow-up after creating liquid organic fertilizer on its own

Endophytic bacteria are defined as a group of microbes that live in plant tissues that do not cause disease and are mutually related to the host plant, can be isolated from all parts of the plant were roots, stems, leaves, and seeds. Endophytic bacteria have the potential to produce natural products for agriculture, increase plant growth, and support the sustainable development of agriculture. The growth of endophytic bacteria in vitro generally uses a medium that contains nutrients including macronutrients, namely elements (C, H, O, and N), micronutrients, namely non-metallic elements (S and P), metallic elements (Ca, Zn, Na, K, Cu). , Mn, Mg, and Fe), vitamins, water, and energy. To meet these growth requirements, currently the growth and propagation of endophytic bacteria generally still use synthetic media which are expensive and in the field, mainly by farmers, are not easy to obtain. The study aimed to obtain an alternative medium made from beans for the growth and propagation of endophytic bacteria from lowland eggplants. The types of beans were soybeans, green beans, red beans, cowpeas, peanuts, and Nutrient Agar (NA) as control. Inoculation into the medium was done using the spread plate technique. This technique is preceded by a dilution and at dilution of 10-7 was taken 0.1 ml then to be spread on the growing medium. Observations were growing and colony counting was done 24 hours after inoculation. The results were: (1) endophytic bacteria from lowland eggplant can grow well on all mediums with the best growth on NA medium, (2) all media can be used as the propagation of endophytic bacteria from lowland eggplant plants, (3) the assumed of the growth curve is logarithmic with 4 phases were lag phase, exponential phase, stationer phase, death phase.

From the conservation standpoint, critical land is land that can no longer function to operate the water system, soil resources, and biodiversity that lives on the land. Critical land exhibits signs indications of environmental degradation as a result of numerous sorts of improper land resource utilization. The impact of critical land results in a decrease in the function of conservation, production function, and socio-economic life of the community. The Sumadi Farmer Group encountered hurdles downstream (marketing) and upstream (cultivation) due to limited land use and lack of human resources who understood plant conservation systems. Therefore, this community service aims to preserve critical land with biological conservation methods by improving soil quality, cultivating healthy plants, and controlling pests and diseases using vegetable pesticides. The activity began with the observation of agroforestry planting land, then socialization and presentation of material by the team of lecturers, followed by demonstrations on the land, and ended with an evaluation. Empowered with an understanding of cultivation techniques and restorative plant care, the Sumadi farmer group is passionate about developing an organic farming system to overcome land issues

Ngadilegi Utara Hamlet is one of the hamlets in Plinlahan Village, Pandaan District, Pasuruan Regency which has large potential land for cultivating plants. Farmers in Ngadilegi Hamlet grow many crop commodities, one of which is melons. Melon (Cucumis melo L) is an annual fruit plant originating from the Persian Hot Valley or the Mediterranean region which is the border between West Asia, Europe and Africa. Melon plants are a type of pumpkin plant which is in the same family as watermelon, cantaloupe and cucumber. One effort to increase melon production in North Ngadilegi Hamlet can be done by good development and correct cultivation technology and supported by the use of new technology, namely the use of bacteria contained in PGPR. Soaking seeds with PGPR aims to ensure that the bacteria contained in PGPR are able to colonize the seeds as early as possible. Proper long soaking treatment of seeds can increase plant yields because bacteria will bind to the seed coat and imbibition into the seeds.

The use of biological agents such as Bacillus sp. bacteria has begun to be widely used by farmers as a new form of control. Bacillus sp. needs to require special methods in its application because it has certain living conditions, and Bacillus sp. is vulnerable to environmental pressures. Bioencapsulated formulation in the form of granules is considered effective as a form of bacterial application in soil because it is able to protect Bacillus sp. and maintain survival. This study aims to determine the best concentration of sodium alginate in maintaining the viability of Bacillus sp. at the in vitro stage and to see changes in the size of the beads. The beads were made using extrusion method by combining Bacillus sp. suspension and sodium alginate suspension at 1%, 1.5%, and 2% concentration. The concentration of sodium alginate was not a major factor in changes in bead size and viability test results experienced significant changes in each observation. 1.5% and 2% concentrations can reach the highest viability value of 3x106 CFU/mL and decreased during 1 month of observation. Changes in bead size and viability were caused by the alginase enzyme produced by Bacillus sp.

Biological agent Bacillus sp. Based on the results of previous research, direct use of isolated microorganisms BCZ14, BCZ16, and BCZ20 was able to suppress Fusarium wilt disease. However, Bacillus sp. formulations in suspension form are less effective when applied in the field. This research focuses on analyzing the viability of three isolates of Bacillus sp. against several combinations of bioencapsulation coating materials. The experimental design used was a completely randomized design with a combination of treatment of three isolates and three types of coating materials, namely sodium alginate (B1), carrageenan (B2), and chitosan (B3) each 2%. Each treatment combination was repeated five times. Based on the experiments that have been carried out, the bioencapsulation formulation using 2% chitosan coating material was able to maintain the viability of the three isolates of Bacillus sp. BCZ14, BCZ16, and BCZ20. The population density of the three isolates of Bacillus sp. persisted consistently from the first week to the last week of observation. Therefore, the 2% chitosan coating material can be said to be able to maintain the viability of Bacillus sp. within six weeks.
