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

ABSTRACTThe purpose of this study was to determine the effect of both interaction and primary administration of Growtone ZPT and NASA POC on vegetative growth, Vitamin C content and flavonoids in Young Moringa plants. This research was carried out in the Experimental Garden of the Faculty of Agriculture, Riau Islamic University. This research was conducted for 4 months, from June 2019 to September 2019. This study used a Factorial Complete Randomized Design (RAL) consisting of the first 2 (two) factors (Growtone immersion duration) with a concentration of 50 ppm consisting of 4 (four) levels: L1 (20 minutes), L2 (40 minutes), L3 (60 minutes). The Second Factor (Nasa POC concentration), consists of 4 (four) levels: K0 (without treatment), K1 (2 ml / l water), K2 (4 ml / l water) and K3 (6 ml / l water). Data were analyzed statistically and continued with further tests of Honestly Significant Difference (BNJ) at the 5% level. Based on the results of research that has been conducted concluded that: The interaction of soaking time treatment and the concentration of real Nasa POC on the percentage of growth, number of leaf stalks, fresh leaf weight, number of leaflets. The best treatment was the growtone soaking treatment 40 minutes and the concentration of POC Nasa 6 ml/l water (L2K3). The main effect of growtone soaking time was apparent in all observational parameters. The best treatment is soaking for 40 minutes (L2). The main effect of real Nasa POC concentration on all parameters observed. The best treatment is the concentration of POC Nasa 6 ml/l water (K3). Giving growtone treatment with immersion for 40 minutes and POC NASA concentration by administering 4 ml per liter of water (L2K2) gives the best treatment results on the content of vitamin C,and  flavonoids  Moringa plants.
