Socialization  and  Practice  of  Utilizing  Household  Organic Waste Remains in the Process of Making Liquid Organic Fertilizer (POC) in Talang Karet Village. Through this activity it is hoped that it will provide education and understanding to the public to maintain a clean environment and provide education in recycling the remains of organic waste to make it more useful. As for the activity of utilizing organic waste from leftover household vegetables as an  alternative  medium  in the  planting process  of  administering liquid organic fertilizer, it is hoped that it can make the yard of the house a place to grow crops and can help the people of Talang Karet Village in meeting their needs for vegetables for their daily needs. days and can also make it an additional source of income.

Kampung Depet Indah is one of the villages in the Celala District, Central Aceh District. Kampung Depet Indah is located in an area that is remote in the District of Celala with its vast natural potential with agricultural land and plantations. Based on the results of surveys conducted on several farms and plantations, there are still many farmers who on average use chemical fertilizers as a source of additional or substitute nutrients needed by plants to support growth. One of the work programs being carried out is the manufacture of liquid organic fertilizer (POC) from banana peel waste, where POC itself is a liquid organic fertilizer that can be used by farmers as a provider of nutrients for plants and crops. The implementation of making POC up to the socialization stage to the community consists of several stages which include: (1) Preparation of tools and materials (2) Making POC as a sample (3) Making POC posters (4) Socializing POC to the community (5) Question and answer session.

Organic waste is waste that can be decomposed such as food scraps, fruit, leaves, and so on. One of the factors that affect the environment is the problem of waste disposal and management. There are various ways to overcome the problem of organic waste, one of which is by processing organic waste into liquid organic fertilizer. In this research, the manufacture of liquid organic fertilizer used waste of banana peels, pineapple peels and dragon fruit peels with the addition of tape yeast and EM-4 bioactivators. The purpose of this study was to determine the effect of bioactivator concentration and type of bioactivator on phosphorus content in liquid organic fertilizer. The method used in this study is an experimental method using a randomized block design. Based on the results of the study, it was found that the concentration of bioactivators did not affect phosphorus levels in liquid organic fertilizer, but the type of bioactivator affects the phosphorus content in liquid organic fertilizer. but the type of bioactivator affects the phosphorus content in liquid organic fertilizer. The addition of 5 ml, 10 ml and 15 ml of EM-4 bioactivator resulted in phosphorus levels of 204.35 ppm, 217.85 ppm and 215.87 ppm respectively. The addition of 5 ml, 10 ml and 15 ml of tape yeast bioactivator resulted in phosphorus levels of 156.53 ppm, 134.07 ppm and 136.21 ppm respectively. The best treatment obtained in this study was the addition of 10 ml of EM-4 bioactivator, but the levels of phosphorus produced do not meet the standards of the Ministry of Agriculture No. 28 of 2009.

PKM is one part of the learning process that is applied directly in the community. Which focuses on "Agricultural/Fisheries Technology Management" (Manufacture of Liquid Organic Fertilizer (POC)). Lembang Mappa' is one of Lembang whose economy lies in the agricultural and plantation sectors. Almost all residents in Lembang Mappa' work as farmers. There is one problem that has not been resolved, namely how to make organic fertilizer whose ingredients are easily available in Lembang Mappa'. The activity of socializing and making liquid organic fertilizer from gamal leaves, rice washing water, brown sugar or granulated sugar, EM4 was carried out three times with socialization to the public about how to make liquid organic fertilizer and its application to plants. After this activity, it is hoped that farmers will be able to make their own liquid organic fertilizer at home, so they can save money on purchasing fertilizer.
