Abstract

Organic fertilizer is fertilizer made from decomposed plant, animal, and human waste, produced from various types of organic materials with different properties and characteristics. Bekiung Village is one of the villages that cultivates oil palm plants. However, the utilization of oil palm waste, such as fibers, empty fruit bunches, and liquid waste from oil palm mills, is still limited or has not been effectively utilized by the community, which can cause negative impacts on the environment if left to degrade, while on the other hand, this waste has a high nutrient content. The Community Service Activity based on the Community Empowerment Scheme in the form of making solid organic fertilizer from empty fruit bunches and liquid waste from palm oil mills was carried out at BUMDEs Bangun Mandiri, Bekiung Village, Langkat Regency, in August 2024. The preparation of tools and materials consisted of 100 kg of empty palm fruit bunches, 200 kg of dried palm oil mill effluent, and a bioactivator. Next, the grinding process was carried out using a Hummer mill machine. The results obtained were an organic fertilizer capacity of ±300kg with a fermentation time of 21-35 days with a nitrogen content of 0.21% in the low category, P2O5 of 0.12% in the medium category, K2O of 1.09% in the high category, C -Organic at 2.30% in the low category, Ca at 1.57 me/100g in the medium category, Mg at 0.49 me/100g in the high category, pH at 6.34 in the neutral category, and KTK and moisture content at 15.20 me/100g and 10.28%, respectively.

Abstract

Sido Mulio Hamlet is a village with a lot of vacant land that can be used for hydroponic farming. This community service activity aims to increase the knowledge, skills, and empowerment of the community through training in organic hydroponic vegetable cultivation in support of the development of village edu-tourism. The activity was carried out from April to November 2025 using a participatory approach through the stages of socialization, training, production practice, mentoring, and evaluation. The method used was pre-experimental with measurements taken before and after training. Data were collected through questionnaires, observations, and focus group discussions, then analyzed descriptively. The results of the activity show a significant increase in community knowledge related to hydroponic cultivation, irrigation system installation, and plant nutrition management. This increase in knowledge contributes directly to improved practical skills and independent adoption of hydroponic technology. In addition, this activity has an impact on increasing the economic capacity of the community through the production of hydroponic vegetables and their use as a means of agricultural education. This activity confirms that practical organic- based hydroponic training supported by mentoring can have a real impact on community empowerment and the strengthening of community-based rural edutourism.
