Introduction The urban farming program in the city of Surabaya is one of the manifestations of the Surabaya City Government's policy to achieve food security.
Urban farming, which utilizes vacant land, has been implemented by the Surabaya City Government since 2017 (Athariyanto, 2.
Broadly defined, urban farming is an activity program that involves not only agriculture, but also livestock farming, aquaculture, agroforestry, and horticulture (Wijaya et al.
, 2.
One of the urban villages in Surabaya that implements urban farming is Gayungan Village.
Gayungan Village has several sectors within its urban farming initiatives, such as: a vanilla garden, a tabulampot .
otted fruit plan.
garden, maggot cultivation, a wastewater treatment facility, and oyster mushroom cultivation.
The growing trend of urban farming and oyster mushroom cultivation in Gayungan Village often leads to new problems.
Oyster mushroom cultivation can produce waste in the form of used baglogs that have already been harvested and are no longer active in producing Several mushroom farmers face limitations in land and facilities to manage these used baglogs.
The accumulated waste not only causes unpleasant odors and attracts pests, but is also often discarded carelessly due to a lack of understanding about its recycling In some cases, a single harvest cycle of oyster mushroom cultivation can produce up to 6 tons of baglog waste (Jumar et al.
, 2.
The community of Gayungan sub-district cultivates oyster mushrooms in a designated area located in RW 03.
This site includes one mushroom house .
with a capacity of 5,000 baglog units.
In a single harvesting cycle, the waste generated from these baglogs can reach approximately 1 ton.
This baglog wasteAiconsisting of old and contaminated baglogs refers to the spent growing medium that is no longer productive (Aris Priyanto, 2.
Without proper management, the accumulation of this waste may lead to environmental issues, such as air pollution and soil quality degradation in the disposal area.
Therefore, sustainable waste treatment efforts are essential to minimize the negative environmental impacts (Susilowati et , 2.
The baglog waste still contains several essential nutrients required by plants and has the potential to improve soil nutrient content.
The nutrient composition of baglog waste includes phosphorus (P) at 0.
7%, potassium (K) at 0.
02%, total nitrogen (N) at 0.
6%, and a high organic carbon (C-organi.
content, reaching up to 49.
These contents make baglog waste a valuable organic material for enhancing soil fertility and quality (Hunaepi et al.
, 2.
Due to this nutrient content, spent mushroom substrate holds significant potential to be processed into organic fertilizer.
Mushroom cultivation waste can be utilized through composting to produce organic compost fertilizer, which improves soil quality and supports plant growth.
In addition.
Stated that one of the alternative methods for waste management is utilizing spent mushroom baglog as a raw material for organic fertilizer production through the composting process.
Similarly, (Juniartini, 2.
that composting not only serves as a waste management strategy but also has the potential to reduce air pollution caused by waste incineration and to suppress methane gas emissions from decaying organic waste at disposal sites, due to the activity of methanogenic bacteria.
Moreover, the use of compost is also known to improve soil structure and characteristics (Bria et al.
, 2.
The conversion of baglog waste into organic fertilizer not only supports efforts to reduce environmental pollution but also utilizes its natural properties as an organic material that has already undergone partial decomposition.
As a result, the composting process is relatively faster compared to other organic materials.
While the general production of organic fertilizer typically requires 2 to 3 months (Arum, 2.
, the processing of mushroom waste into organic fertilizer takes approximately only 1 month (Alam et al.
, 2.

Method The implementation of the training program on the processing of oyster mushroom baglog waste into organic fertilizer in Kelurahan Gayungan began with a needs assessment conducted through surveys of local residents.
This assessment aimed to evaluate the communityAos knowledge, skills, and interest in utilizing baglog waste as raw material for organic fertilizer.
The findings served as the foundation for designing a training curriculum that was relevant and tailored to the characteristics and needs of the community.
The curriculum encompassed theoretical aspects such as the physicochemical properties and nutrient content of baglog waste, the basic principles of composting, and the concepts of sustainable agriculture (Rastono et al.
, 2.
To enhance participantsAo understanding, the program also incorporated practical sessions.
The outreach and training activities were carried out in Kelurahan Gayungan.
Gayungan Sub-district.
Surabaya City.
East Java Province, involving active participation from the community, particularly oyster mushroom cultivators.
Baglog waste, which had previously been discarded without further processing, actually contains high levels of organic matter and can be utilized effectively if properly managed.
Therefore, the program commenced with a socialization phase to raise awareness about the untapped potential of baglog waste.
Following the socialization, technical training sessions were conducted, emphasizing practical and applicable approaches.
The training covered the stages of organic fertilizer production, including material collection, ingredient mixing, fermentation, and evaluation of compost maturity.
Participants were taught to use dry leaves and banana peels as additional materials to accelerate the decomposition process (Salman et al.
, 2.
These materials, along with baglog waste, were mixed in plastic containers and stirred until homogeneous.
Subsequently, a solution of EM4, molasses, and water was added in appropriate amounts and stirred again to ensure thorough mixing.
The containers were then sealed tightly to create optimal fermentation conditions.
During the fermentation process, the mixture was stirred every 3 to 5 days to maintain aeration and support the activity of decomposing microorganismse (Matheus & Kantur, 2.
Through this initiative, participants not only gained theoretical insights but also acquired practical skills that could be independently applied in their local environments.
It is expected that the community will be empowered to manage oyster mushroom cultivation waste into useful and environmentally friendly products, thereby contributing to environmental quality improvement and the advancement of sustainable urban agriculture (Subekti et al.
Result The training program on organic fertilizer production from oyster mushroom baglog waste in Gayungan Village demonstrates comprehensive assistance through a series of structured activities.
These activities include community outreach, participatory training, and hands-on composting practice.
Technically, the program begins with an awareness-raising phase to highlight the hidden potential of mushroom cultivation waste, followed by practical sessions where participants are trained in mixing materials, fermentation processes, and harvesting mature compost.
The direct application of these skills is evident, as some participants successfully processed mushroom bag waste into organic fertilizer used for household-scale farming and community-based agricultural activities.
This program effectively improves waste management practices by transforming previously discarded baglog waste into valuable organic fertilizer.
This transformation contributes to reducing dependence on chemical fertilizers and promotes environmentally friendly agriculture, positively impacting local soil health, micro-ecosystem balance, and overall environmental quality.
The integration of composting activities into urban agriculture and edutourism initiatives also expands the relevance and appeal of sustainable practices among the community.
