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

ABSTRACTDomestic waste pollution has been among serious problem recently. Detergent contributed significantly lead to eutrophication as well as toxic to the environtment. A simple technology could be applicated by wetland system, in which bamboo were planted. The objective of the present study were to reduced level of detergent, Methylene Blue Active Substances (MBAS) by the bamboo wetland system. A laboratory experiment were conducted with Completely Randomized Design (CRD) with two factors including initial MBAS concentration, and residence time. Factors operating conditions were performed following Taguchi Methods. It revealed that the system has MBAS reduction efficnicy of 85,11%. The residence time significantly reduce the detergent concentration with a regression Ŷ = 12.22-0.4X2, with coeficient determination R = 79,46, apparently, four factors; initial detergent concentration, residence time, aerobic condition, and soil type (Podzolik Red Yellow) that affect the decreasing of MBAS level, with percentage of 9,11%, 8,34%, 2,68%, and 0,29% respectively.Key words: management, detergent, bamboo

Abstract

Management of peat soil for pineapple cultivation in Kualu Pineapple Village is still very traditional. In planting not using spacing, fertilization only uses fertilizers containing N, namely urea. In addition, there are differences in principles in managing peat, namely that there are farmers who add ameliorant ingredients and some do not. The purpose of this study was to determine the chemical properties of the soil, and nutrient uptake of pineapple plants in Kualu Nenas Village where the soil was given dolomite lime ameliorant and without ameliorant. This research method uses qualitative (survey) and quantitative (laboratory analysis) methods. A sampling of plants whose soil was given dolomite lime ameliorant and soil without ameliorant was carried out by purposive sampling technique. The research data were analyzed by a T-test to determine the difference between the chemical properties and nutrient uptake of pineapple plants. The T-test was analyzed using the SAS program (SAS User Manual Version 9, 2004). The results of this study were that the soil PH, P-available, K-dd, Ca-dd, Mg-dd, CEC, and base saturation content in pineapple plantations where the soil was treated with dolomite lime ameliorant had a significantly higher value based on the T-test compared to pineapple plantations with no ameliorant. Nutrient uptake of N, P, K, Ca, and Mg in pineapple leaves was not significantly different between plants whose soil was treated with dolomite lime ameliorant and those without ameliorant.

Abstract

The purpose of this study was to determine the interaction and main effects of biochar residue and POC NASA applications to increase growth and production and nutrient uptake of peanut plants. This research has been carried out at the Experimental Garden of the Faculty of Agriculture, Riau Islamic University, Pekanbaru City. The research was carried out for 4 months from January to April 2021. The design used in this study was a factorial completely randomized design (CRD) consisting of 2 factors, the first factor was biochar residue (B) which consisted of 4 treatment levels, namely biochar dose 0; 0,7; 1.4; 2,1 kg per plot. The second factor is POC NASA which consists of 4 treatment levels, namely POC NASA concentration 0; 3; 6; 9 ml/L of water. Parameters observed were relative growth rate, number of pods, the weight of wet pods per plant, the weight of dry pods per plant, and nutrient uptake of N, P, K in plants. Observational data from each treatment were statistically analyzed and continued with the further test of Honest Significant Difference (BNJ) at the 5% level. The results showed that the residue biochar and POC NASA had a significant effect on all observed parameters except for plant nutrient uptake parameters of N, P, and K. In terms of interaction and main, the best treatment was biochar residue, the dose of 2,1 kg/plot and POC NASA with a concentration of 9 ml/liter of water (B3P3).

Abstract

Onion production in Riau Province is still low, while the demand is quite large. Therefore, it is necessary to increase production. This study aimed to determine the effect of the application of oil palm ash and various types of organic fertilizers on ultisol soils on the growth and production of shallots. The design used was a completely randomized factorial design consisting of 2 factors. The first factor was the provision of oil palm ash which consisted of 4 levels of treatment, namely: 0, 200,400, and 600 g/plot. The second factor is various types of organic fertilizers which consist of 4 levels of treatment, namely: without giving organic fertilizer, chicken manure, tankos compost and corn litter bokashi. The parameters observed were plant height, number of tubers per clump, wet tuber weight per clump, dry tuber weight, percentage of tuber weight loss, relative growth rate and nutrient uptake. plants, number of tubers, wet weight per clump, dry weight per clump and tuber weight loss, the best treatment was giving palm ash 400 g/plot and corn litter bokashi. The main effect of giving palm ash bunches was real on all observation parameters, the best treatment was 400 g/plot. The main effect of organic fertilizer was real on all observed parameters. The best treatment was corn litter bokashi.
