Abstract

Nagari Lawang is located in Agam Regency, West Sumatra, which is a nagari situated in the highlands with a slightly steep to very steep slope with the most types of land use in moors/fields. This can directly encourage erosion. This study aims to analyze the optimal land use pattern for reducing the rate of erosion in Nagari Lawang. The method used to calculate the erosion rate is the Universal Soil Loss Equation (USLE) and to obtain the optimal land use in reducing the erosion rate is a simulation with three scenarios. The results of the study showed that 47.29% of the Nagari Lawang land area was at an erosion rate above the tolerance erosion with the category of light to very heavy. Based on land use simulations, planning scenario III by allocating the use of shrubland into mixed gardens with planting according to contour lines and the use of shrub land into mixed forests is the best scenario because it can reduce erosion by 39.05% of the total erosion of Nagari Lawang. The reduction of erosion on the diverted land (moors/fields and shrubs) reached 45.83% of the existing condition, which was 2105.928 tons/ha/year. The best scenario land use can be used as a reference by policy makers and the community in determining appropriate land management actions in Nagari Lawang. Keywords: Erosion, Simulation, Land Use, USLE.

Abstract

Hydroponics is a modern agricultural innovation that uses water and nutrient solutions as a substitute for soil, making it more efficient, resource-efficient, and environmentally friendly, and allowing it to be implemented on small plots of land. These advantages make hydroponics a strategic solution for supporting food security, particularly through the involvement of the younger generation to foster innovation and creativity in agriculture. This Community Service (PKM) activity aims to introduce the concept of modern agriculture to the younger generation through hydroponic plant cultivation at SDIT Arafah in Padang. The activity targets elementary school students as part of an effort to instill knowledge, interest, and concern for agriculture from an early age. The implementation method included a coordination phase, the construction of a simple hydroponic system, outreach through lectures, educational videos, and hands-on demonstrations, as well as evaluation using pre- and post-tests. Monitoring was conducted 15 days after planting to assess the program’s sustainability and plant growth. The results of the activity showed an increase in students’ understanding of the basic concepts of hydroponics, the types of plants that can be grown, and the principles of plant nutrition and care. The students’ enthusiasm was evident in their active participation during the activity and their ability to explain the principles of hydroponics. Monitoring revealed optimal growth of the lettuce plants as well as consistent maintenance of the system by students and teachers. Overall, this program has been effective in enhancing students’ knowledge, interest, and positive attitudes toward modern agriculture. This initiative has the potential to serve as a model for contextual education that supports the development of a younger generation committed to agricultural innovation, environmental sustainability, and future food security
