Abstract

This unlicensed gold mining activity (PETI) can have a positive impact on the economy of the community, in the form of increased incomes so that it can improve the welfare of the community. However, besides having a positive impact, PETI's activities will harm the environment around the mining area. The negative impact caused by mining activities is environmental damage in the form of a decrease in land quality as indicated by a decrease in physical, chemical and biological soil quality. The purpose of this study was to determine the nutrient content and the total of microbes in former PETI soils in sub-districts of the Kuantan Singingi Regency. The parameters observed were analysis of nutrient content consisting of analysis of sand, dust, clay, soil pH, C-organic, N-total, P2O5, K2O, interchangeable cations, CEC, a saturation of bases, Aluminum Saturation, and analysis of total soil microbes. The results showed that the Singingi sub-district, Central Kuantan sub-district, Sentoja sub-district, and Logas Tanah Darat sub-district has the texture of sand soil clay to sand, the content of pH H2O Land classified as fertility is very sour, C-Organic (%), Ca-dd, Nitrogen-Total (%), Mg-dd and CEC with very low fertility criteria, C/N Ratio with low to very low fertility criteria, K-dd content with low criteria, Na-dd with moderate to very high criteria, aluminum saturation is very high with wet saturation the fertility criteria are low. The total microbes in the Sub-district of Sentoja Raya and Logas Tanah Darat Sub-district are much higher than Singingi Sub-district and Central Kuantan Sub-district.

Abstract

This community service activity aims to improve the knowledge and skills of the community, particularly women in the Family Welfare Movement (PKK), in sweet corn cultivation as an effort to optimize the use of yard land and strengthen household food security. The activity was conducted in Tanah Merah Village, Siak Hulu District, Kampar Regency, using a participatory approach. The methods used included outreach, technical cultivation training, interactive discussions, and ongoing mentoring. The material provided covered selecting superior seeds, planting techniques, fertilization, pest and disease control, and harvesting and post-harvest stages. The results of the activity demonstrated an increase in participants' understanding and skills in applying proper sweet corn cultivation techniques. Furthermore, there was a shift in community attitudes, leading to greater awareness of the importance of productive and sustainable yard land use. This activity also encouraged the emergence of small-scale, home-based agricultural initiatives with the potential to increase family income. Thus, this program not only contributes to community capacity building but also supports food independence and sustainable economic well-being at the local level.
