Abstract

The replanting process in plantation sectors generates significant biomass waste that is often underutilized. This study aimed to valorize felled trunks from replanting activities into a value-added food commodity at PT. Barumun Agro Sentosa. The method employed was participatory action research, comprising field observations, interviews, and production demonstration plots conducted in September 2025. Sap collection was performed using the apical meristem tapping technique on felled trunks aged approximately 25 years. To ensure quality and prevent fermentation, the sap acidity was maintained at a pH of 6.0 to 7.0 using natural preservatives before undergoing thermal evaporation. The results indicated that the average sap productivity ranged from 1.7 to 2.5 liters per trunk per day. The final product exhibited a solid texture, dark color, and distinctive savory-sweet taste comparable to traditional palm sweeteners. It is concluded that processing sap from felled trunks is technically feasible and supports the concept of zero waste agriculture. This practice offers a viable economic alternative for local communities and plantation workers by transforming residue into profitable resources.

Abstract

Organic waste management remains a significant environmental issue, particularly in school settings, where waste from daily activities is not managed effectively. Improper management of organic waste may contribute to environmental pollution and reduce ecosystem quality. This activity aimed to enhance students' environmental awareness through training on the production of liquid organic fertiliser (LOF) derived from organic waste at SMA Negeri 2 Padang Bolak, North Padang Lawas Regency. The activity was implemented through several stages, including the delivery of educational materials, demonstrations of LOF production, direct practical activities, and mentoring in the application of LOF to plants within the school environment. The LOF production process utilised vegetable and fruit waste fermented with water, EM4, and molasses for 2–4 weeks. The effectiveness of the activity was evaluated by assessing students' knowledge gains using pre- and post-tests. The results demonstrated an improvement in students' understanding of LOF concepts, production techniques, and their benefits after participating in the training. Furthermore, monitoring results indicated that the produced LOF had appropriate fermentation characteristics, including a brownish colour, a distinct acidic fermentation odour, and a pH value of approximately 5, indicating its suitability for plant application. This activity contributed to improving students’ knowledge, practical skills, and environmental awareness, particularly in promoting sustainable organic waste management and encouraging environmentally friendly practices within the school environment.
