Banana peel is banana processing waste that can be used as poultry feed, but because of its high crude fiber content, it is necessary to do processing to reduce it, one way is by processing processes such as fermentation. The fermentation process takes time to get good nutritional results. This study aims to determine the content of crude protein, crude fiber and crude fat of banana peels fermented with SOC at different times. This study used an experimental method with a Complete Randomized Design with three treatments and six repeats. The three treatments are W0= (0 hours), W1= 24-hour fermentation, and W2= 72-hour fermentation. The observation parameters are crude protein content, crude fiber, and crude fat.  The results showed that the SOC Fermented Kepok banana peel nutrition showed the highest crude protein analysis results were P2 with an average crude protein of 22.14% and differed very markedly from P1 and P0, with the lowest crude protein average at P0: 10.20%. The results of the analysis of the highest crude fiber content were P0 with an average crude fiber of 22.38% and differed very significantly from P1 and P2 with the lowest average crude fiber at P2: 15.30%. The highest crude fat content analysis was P2 with an average crude fat of 16.67% and differed markedly from P1 and P0, with the lowest average crude fat at P0; 13,71%. Fermentation of kapok banana peel with SOC for 72 hours produced 22.14% protein, 15.30 crude fiber, and 16.67% crude fat.

Organic waste is still a problem that needs to be resolved. Piles of organic waste can cause the emergence of methane gas (CH4), giving rise to an unpleasant odor and can even potentially cause disease. The aim of this community service is to provide understanding, knowledge and skills to the community regarding how to utilize household organic waste in the form of fruit and vegetable waste into eco-enzymes by fermentation. eco-enzyme is a multi-purpose liquid that can be used to purify waste water, as a household cleaning product, as a detergent, as a pest control product, to remove pesticide residues, and also as an organic fertilizer for plants. The method used is Participatory Action Research (PAR) where the service team is integrated into the community and works with the community to increase the knowledge and abilities of the people who are members of the Women Farming Group (KWT) in understanding and changing the community to become better, more empowered and knowledgeable. The results of this activity were able to increase the understanding, knowledge and skills of Women Farmer Groups in 4 Districts of Bandar Lampung city both conceptually and practically, and have the awareness not to just throw away organic waste, but to use it because it not only protects the environment but also provides benefits to the community. This activity was considered successful and sustainable for future programs.  

The purpose of this activity is so that the environment of Batu Bersurat Village, XIII Koto Kampar District, Kampar Regency can become a clean and uncontaminated environment from cow dung. Cow dung can be processed into compost. Compost is an organic fertilizer made from animal waste that has undergone a fermentation process. The advantage of this compost is that it is environmentally friendly, can increase the income of farmers, and can increase soil fertility by repairing physical damage to the soil due to excessive use of inorganic (chemical) fertilizers. Batu Bersurat Village is an area with potential in agriculture, plantation and animal husbandry. The existence of cattle owned by the community has the potential to be used as compost which can be used for agriculture as well as for the fertility of plantation crops. However, the lack of knowledge of residents about the methods and benefits of making compost from cow manure causes cow manure to be thrown away, therefore people still use chemical fertilizers as a medium for the fertility of their plants. Therefore, a practice was held to make use of compost from cow manure in Batu Bersurat Village, District XIII Koto Kampar, Kampar Regency.

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.

Shallot is a horticultural commodity that has good market prospects because it contains high nutrition and can be used as spices and ingredients for traditional medicine. However, shallot production in Indonesia still often fluctuates and even experiences a shortage in meeting the needs of domestic consumers. To increase shallot production, this can be done through intensification efforts, namely by improving cultivation techniques, such as the use of organic fertilizers, proper fertilization, and the use of superior varieties. This study used a factorial randomized block design consisting of 2 treatment factors, namely factor I, fermented NPK ( F) consisting of 0 ml, 250 ml, 500 ml and 750 ml. Factor II was the variety (V) of the Brebes Bima variety, the Probolinggo variety and the Nganjuk variety. The parameters of plant observation were: plant height (cm) and production per plot (g). The data analysis method was a factorial randomized block design (RBD). The results showed that the application of fermented NPK and the use of varieties had a very significant effect on the parameters of plant height (cm) and production per plot (g).

Pharmaceutical biotechnology products in the form of hand washing soap with an active ingredient of telang flower kombucha fermented solution have the potential to inhibit the growth of Staphylococcus capitis, Bacillus cereus, and Pantoea dispersa bacteria. The aim of this study was to formulate and prepare hand washing soap with an active ingredient in a solution of seagrass kombucha fermentation to inhibit the growth of Staphylococcus capitis, Bacillus cereus, and Pantoea dispersa. This research is an experimental laboratory by making 4 hand washing soap preparations, which consist of a hand washing soap base without an active substance. Hand washing soap base added to a solution of fermented butterfly pea flower kombucha at a sugar concentration of 20%, 30%, and 40%. Disc diffusion is a method used to calculate the average diameter of the inhibition zone for the three tested bacterial growth. The research data obtained were analyzed through one way ANOVA and post hoc analysis. The results of the ANOVA test proved that the obtained p value <0.05, which means that there were significant differences in the three treatment groups in inhibiting the growth of the three test bacteria. The post hoc analysis results also proved that 40% concentration was the best concentration in inhibiting the growth of the three tested bacteria, namely 18.34 mm (S. capitis/strong), 16.39 mm (B. cereus/strong), and 13.33 mm (P. disperse/strong).
