Organic waste is one of the major environmental problems caused by household activities. Improper waste management leads to environmental pollution and health risks. This community service activity aimed to educate and train the community in processing organic waste into ecoenzymes as a multifunctional and environmentally friendly product. The method used included socialization, training, and direct assistance to the community in producing ecoenzymes from fruit and vegetable waste through fermentation. The results showed that the community was able to understand the benefits and production process of ecoenzymes and began implementing them in daily life and agriculture. Ecoenzymes can be used as natural cleaning agents, plant fertilizers, and pest repellents. This activity contributes to reducing organic waste and improving environmental awareness and sustainable agriculture practices.

This community service aims to optimize the use of local potential in Ujong Tanoh Darat Village, Meureubo District, West Aceh Regency, in order to improve community welfare and realize village independence. Local village potential, such as natural resources, cultural diversity, and rich local wisdom, have not been optimally utilized, one of which is the management of plastic and household waste. This program focuses on community empowerment through skills training in processing waste into products of economic value, such as handicrafts from plastic waste and ecoenzymes from organic waste. As a result, the community gains new skills that can increase family income, reduce plastic waste, and increase environmental awareness. In addition, this program creates new economic opportunities through marketing local products and strengthening cooperation between residents. The sustainability of this program is expected to continue to support village economic independence, with support from the village government in developing environmentally friendly local potential-based businesses.

Surabaya as the second-largest city in Indonesia, faces serious challenges in waste management with daily waste generation reaching 1,800.05 tons in 2023, exceeding the capacity of Benowo landfill of 1,400 tons per day. Responding to this excess of 300 tons of daily waste, the Environmental Agency (DLH) of Surabaya City initiated the Zero Waste Village program. This program aims to increase public awareness about environmental cleanliness and waste management, implemented through collaboration between DLH and students from UPN Veteran East Java. The methods used include waste banks, composters, takakura, and processing into ecoenzymes. The program stages include sampling determination, initial waste weighing, intensive socialization, and final weighing. The results are encouraging, with a significant reduction in waste generation to an average of 0.19 kg per day per person after socialization. This success demonstrates the program's effectiveness in changing community behavior and reducing waste volume, providing hope for more sustainable waste management in Surabaya and reducing the excessive burden on the Benowo landfill.

A shipyard company in Surabaya, which is one of the major industries, generates a large amount of organic waste, including food waste, vegetables, fruits, leaves, and wood. Although this organic waste is a potential source of humus and essential nutrients for the soil, most of it has not been optimally managed. Composting is an effective method to process organic waste into compost, which can reduce the negative impact of toxic compounds and pathogens on the environment. This research aims to evaluate the effectiveness of using two types of activators, namely PROMI and ecoenzymes, in accelerating the composting process and improving compost quality in accordance with SNI 19-7030-2004 standards. PROMI activator, which contains various microorganisms such as Trichoderma Harzianium, Pseudokoningii, and Aspergilus sp., and ecoenzymes, which is produced through fermentation of organic materials, were applied to shredded organic waste. The results showed that the use of both activators could accelerate the decomposition process of organic materials and produce high-quality compost within 21 days. With the final measurement results of both composts, both with PROMI and ecoenzymes treatment, the same pH and temperature values were obtained, namely pH 7 and temperature 30℃. Parameters such as pH, temperature, colour, smell, and texture of the compost are recorded periodically to ensure the composting process is going well. Thus, the use of PROMI and ecoenzymes activators not only increases composting efficiency but also provides a sustainable solution for organic waste management in the shipyard industry.

The shipbuilding industry produces organic and inorganic waste. The organic waste produced by the shipbuilding industry is dry leaves, dry grass, dry wood and other dry materials. Organic waste management is becoming increasingly important in this industry because the industry's very rapid growth has the potential to increase negative environmental impacts if not handled properly. Utilizing organic waste into fertilizer is an activity that can be carried out with the aim of reducing waste around the shipyard industrial environment. This organic fertilizer is made using a simple composting method so that it can be applied in this industry. The composting process involves 2 different treatments, namely the first is an activator solution in the form of a mixture of ecoenzymes, water and sugar solution and the second is using Effective Microorganism 4 (EM 4). The results of the research showed that these two treatments produced a pH that was not much different, namely 6.9 for EM4 and a pH of 7 for the ecoenzymes activator. The temperature of the compost produced in the ecoenzymes mixture treatment was 300C and in the EM4 treatment was 300C. This shows that the activity of decomposing microorganisms is running well.    

Ekoenzyme or Eco enzyme (EE) is the result of fermentation from organic waste in the form of vegetables or fruits, Ecoenzyme products are environmentally friendly products, easy to use, and easy to manufacture, and multi-functional, can be used to increase plant nutrients, so that the soil becomes more fertile, to clean the surrounding environment (environmental sanitation), to clean. mop the floor, clean yourself (bathing, brushing teeth, and others) and to provide air, all of which boils down to helping save our earth. Household organic waste is generated by many people every day. Therefore, one of the efforts for waste management is needed to increase the knowledge of the community in the village of Suka Damai, namely additional information and knowledge and awareness of the community group will make EE as one of the multi-functional products, which can overcome the problem of a lot of waste or organic waste, especially in households, The effort is to overcome and protect the environment, which has a good positive effect that can also be used to fertilize the soil. . The method of this activity was carried out using lecture and discussion methods, as well as hands-on practice. The results of this EE making training can help the community in managing organic waste, both fruit and vegetable waste.

Kandangmas Village through the PKK mobilization team conducts a household waste treatment program one of which is by processing it into eco-enzymes. The stages of this program start from surveys and program planning, introduction of mentoring through workshops and training, monitoring evaluation, review of service results, and final report of service. The results of the household waste treatment program as many as 40% stated that this program is beneficial and 32% stated that it is quite important to be useful. Eco-enzyme products have an aroma favored by partners and are used for various purposes, in particular for anti-septic agents and plant nutrient additives.
