Abstract

The green lettuce and Curly red lettuce have a high potential to be developed as commercial crops on limited land with verticulture cultivation system. The use of this cultivation system must be supported by adequate nutrients and water in addition to optimal environmental conditions. By using the vertical hydroponic plant cultivation method will increase the growth of Curly red and green lettuce plants. The method used is an experimental method and the data is processed using polynomial analysis method and descriptive method. The observation parameters in this study consisted of main parameters (flow rate, power requirement, energy requirement, and water pressure calculation). In addition, supporting parameters were evaluated including plant height, leaf count, fresh weight of plants, plant productivity, and harvest yield. Data were analyzed using descriptive and regression methods. The power requirement used from the initial stage of transplanting to harvest is 640.8 W. The total energy requirement used from the initial planting process to the harvest process is 2563.2 Wh. The average AB mix requirement of each stage of plant is 972.0 ppm; 1231.9 ppm; 1158.1 ppm; 1092.4 ppm. Flow rate is directly proportional to temperature; if the temperature increases, the flow rate for nutrients will increase, and if the temperature decreases, the flow rate will decrease for the fertigation system. Keywords: Energy, Hydroponic, Lettuce, Nutrition, Verticulture cultivation.

Abstract

The limited availability of forage during the dry season and the suboptimal capacity of farmers in Kota Daro II Village, have contributed to insufficient feed supply for cattle and reduce livestock productivity. The potential of available natural resources offers a viable solution to ensure feed continuity throughout the year. The utilization of swamp grass and agricultural waste through the application of haylage technology can serve as an alternative feed source during the dry season. This activity was a community service program aimed at improving the knowledge and skills of farmers in Kota Daro II Village in utilizing swamp grass haylage supplemented with cassava leaves as an alternative feed source during times of feed shortages. This activity was carried out at the Kota Daro II Village Hall on October 8, 2025, with education and training methods for farmers through counseling on the introduction of haylage technology and training, demonstration of haylage production, which was attended by 25 farmers. Evaluation of haylage results after 21 days of storage to see physical quality and palatability testing of haylage. The results showed that the knowledge, understanding, and skills of farmers in Kota Daro II Village had improved regarding the application of haylage technology in utilizing swamp grass and agricultural waste as alternative feed during the dry season. The training was increased farmers’ understanding by 40–46% regarding haylage technology using swamp grass and agricultural waste. Additionally, the interest and motivation of farmers on how to make haylage was quite good, which was marked by a 100% attendance percentage and 60% farmers in interactive discussions.
