Abstract

This research aims to explore the optimization of land clearing techniques in supporting agricultural sustainability in Dahana Tabaloho Village, Gunungsitoli District, North Sumatra. This research involved students of the University of Nias Agrotechnology Study Program who applied land clearing techniques which included weed removal, soil loosening, drainage and bed making. The methods used in this study were direct observation, interviews, and measurement of soil parameters before and after the application of the techniques. The results showed that the combination of traditional and modern techniques in land management can improve tillage efficiency and environmental sustainability. The use of cultivators for soil loosening is proven to speed up the process, but still requires organic fertilizer to maintain the quality of the soil structure. Good drainage is effective in managing excess water and ensuring water availability during the dry season. In addition, making beds with proper direction supports optimal plant growth. The 15% increase in organic matter content and the stability of soil pH to remain neutral are indicators of the success of the applied techniques. Overall, this study provides evidence that proper land management can support sustainable agricultural productivity in the tropics.

Abstract

This community service program was carried out with the main objective of reducing farmers’ dependence on chemical pesticides by introducing and training them in the production of botanical pesticides made from soursop leaves (Annona muricata) and lemongrass (Cymbopogon citratus). The program was implemented in Dusun II Bakaru, Siwalubanua I Village, Gunungsitoli Idanoi District, in collaboration with the Tanjung Morawa Farmers Group as the primary partner. The activities were systematically designed through several stages, including socialization about the negative impacts of chemical pesticides, training in the preparation of botanical pesticides, field assistance during application, and evaluation of the results. During implementation, farmers showed great enthusiasm in participating in every training session. Based on the evaluation results, farmers’ understanding of the benefits and working mechanisms of botanical pesticides increased by 85%. Moreover, the application of these natural pesticides successfully reduced pest attack intensity by up to 70%, which had a positive impact on crop yields. This activity not only provided ecological benefits by reducing chemical residues in the environment but also fostered entrepreneurial awareness among farmers. Several participants even began developing small-scale businesses to produce botanical pesticides independently. Thus, this community service program has made a tangible contribution to realizing sustainable agriculture, enhancing farmers’ self-reliance, and promoting the utilization of local resources as a new economic potential for rural communities.
