Abstract

The main problem faced by the Sumber Rejeki Farmers Group in Percut Village, Percut Sei Tuan District, is the low productivity of rice due to saline land and pest infestations. The high soil acidity and low fertility are the main factors hindering rice growth. To address this issue, the community service team from Universitas Sumatera Utara (USU), in collaboration with student activity units, Himadita Nursery, implemented a program utilizing Liquid Organic Fertilizer (LOF) Jakaba (Eternal Lucky Mushroom) and planting refugia plants. LOF Jakaba, derived from mushroom cultivation, helps reduce soil acidity and increases essential nutrients, thereby improving soil structure. Meanwhile, refugia plants serve as habitats for natural pest predators, enabling ecological pest control and reducing reliance on chemical pesticides. The methods used in this program included socialization, training, and assistance for farmers in producing and applying LOF Jakaba, as well as planting refugia plants. The results of this initiative showed improved soil fertility, reduced pest infestations, and increased rice productivity. The conclusion of this activity is that this sustainable agricultural approach has the potential to serve as a model for other areas facing similar challenges and can enhance the well-being of farmers in Percut Village.

Abstract

Purpose – The purpose of this community service is to improve physical readiness, minimize injuries, and enhance player evaluation quality at Gumarang FC Medan by applying the RAMP warm-up protocol, implementing structured trial management, and using ONCE Sport performance analysis technology. Design/methodology/approach – The activities included socialization, theoretical and practical training, and direct implementation of the RAMP protocol and ONCE Sport technology during training and trial matches. Data were collected using a Likert scale questionnaire and analyzed descriptively to assess coaches' perceptions of the program's effectiveness. Findings – The results show that coaches perceive the RAMP protocol as highly effective (mean 4.56), easy to implement (mean 4.38), and effective in improving physical readiness (mean 4.63) and reducing the risk of injury (mean 4.75). ONCE Sport technology was considered useful (mean 4.44), fairly easy to use (mean 4.13), and very helpful in evaluating players (mean 4.50). RAMP improved agility, speed, and endurance, and ONCE Sport provided objective, data-based evaluations. Originality/value – This community service integrated evidence-based warm-up protocols and performance analysis technology into local soccer clubs. It provides a model that can be replicated by clubs with limited resources to improve training quality and player evaluation.
