Abstract

Soursop (Annona muricata L.) is a tropical fruit plant with high economic value; however, its cultivation is limited by seed dormancy, which delays germination. This study aimed to determine the most effective sulfuric acid (H₂SO₄) concentration for breaking seed dormancy and improving seed viability of soursop. The experiment was conducted at the Greenhouse and Plant Breeding Laboratory, Faculty of Agriculture, Universitas Riau, and implemented using a completely randomized design with four treatments: 0% (control), 70%, 75%, and 80% H2SO4 concentration. Each treatment was repeated five times. A total of 20 experimental units were obtained, each consisting of 25 seeds, for a total of 500 seeds used in the experiment. The results indicated that sulfuric acid treatment significantly affected most germination parameters. Seeds soaked in a 75% sulfuric acid solution exhibited the fastest germination time (28.40 Day After Planting), the highest germination percentage (88.80 %), and the strongest seed vigor (5.55%). These findings suggest that chemical scarification with 75% H₂SO₄ for 30 minutes can serve as a practical and efficient pre-sowing treatment to improve seedling establishment in soursop propagation.

Abstract

National chili demand continues to increase, but productivity at the farmer level remains low due to attacks by the whitefly (Bemisia tabaci Genn.) virus. Benai Kecil Village, Benai District, Kuantan Singingi Regency, Riau, is a horticultural center with low chili productivity (4–5 tons/ha), far below the potential of commonly used superior varieties. This community service activity aims to improve farmers' knowledge and skills in chili cultivation by initiating the use of the superior virus-resistant Neno variety. The program was implemented for five months with stages of socialization, field practice, mentoring, monitoring, evaluation, and follow-up. The results of the activity indicated that farmers improved their understanding and skills in chili cultivation techniques, including seeding, soil cultivation, maintenance, and pest and disease control. The evaluation showed that the Neno chili variety has the potential to be developed because it is adaptive to dynamic climate change and effectively reduces the risk of curly virus attacks. In addition, the use of virus-resistant varieties can also support environmentally friendly pest and disease control. This program demonstrates that the development of the superior Neno variety has the potential to be a sustainable strategy for increasing chili production while simultaneously strengthening food security and farmer welfare.

Abstract

This community service program aims to improve farmers' knowledge and skills in cultivating chili plants and preventing geminivirus infection, a major constraint in production. The activity was carried out through outreach activities covering the stages of land cultivation, virus infection prevention techniques, whitefly population control as a vector, land clearing of weeds that are hosts of geminivirus, sanitation of infected plants, and proper pesticide use. In addition, participants were also introduced to the use of chili varieties resistant to the yellow geminivirus as an alternative sustainable solution. The results of the activity showed an increase in farmers' understanding of healthy cultivation strategies and integrated pest control, with an average score increasing from 45% to 85%, with the vector control aspect increasing from 30% to 90%. This outreach is expected to reduce the level of virus infection and increase chili productivity.
