Abstract

al of Chemistry Volume 4(1):33-42. Artikel 3 Fly-ash (FA) is largely alkaline in nature and contains many essential elements for plant growth along with toxic metals. Therefore, fly-ash is potential to be applied as soil ameliorate that may improve soil properties and plant growth. In this experiment we studied the changes in chemical properties and rice production of acid sulphate soils amended with fly ash. Six different amounts of FA, viz. 0 (100% soil), 5, 10, 20, 40 and 75 tones FA ha-1 were added homogenously to 6 kg of soils in pots of PVC and then chemical properties of acid sulphate soils were observed after a 3-week of incubation. Subsequent of the observation of soil properties, rice was planted onto the pots. Results of study showed that fly-ash application improved soil pH and exchangeable Ca. However, the availability of nitrogen of acid sulphate soils decreased significantly with fly-ash application. The experiment also showed that fly-ash application to soils improved rice growth (height plant, number of tillers, dried-weight root and dried-weight shoot) and rice production. Application 20 tones FA ha-1 resulted in higher rice production than the application 0, 5 and 10 tones FA ha-1, and increasing subsequent the amount of FA application did not significantly increase the rice production. Results of this study demonstrate that low-level fly-ash application resulted in the improvements of soil chemical properties and rice production.

Abstract

Mining activity may potentially produce acid mine drainage (AMD), which has relatively high acidity and dissolved heavy metal concentrations. Constructed wetlands is one of the AMD management methods in which organic matter (OM) plays a very important function in reducing the concentration of heavy metals in AMD through absorption and precipitation processes. Three types of OM (empty fruit bunches of oil palm, chicken manure and water hyacinth) and five levels of OM (0, 10, 20, 30 and 40 Mg ha-1) were applied to reclaimed-mining soils (RMS) in an incubation study. A batch experiment was then performed to measure the effect of OM application on the maximum sorption capacity (Qmax) of iron (Fe) from the AMD onto the mixed soil-OM. The application of OM resulted in increases in soil pH, carboxylic groups, and total functional groups, in which these increases varied based on the types and amounts of OM application. This study also revealed that OM application resulted in increasing Fe sorption. The application of OM increased Qmax values from 2077 to 2348-3259 mg kg-1 (water hyacinth), to 2607-3635 mg kg-1 (chicken manure), and to 2219-2992 mg kg-1 (empty fruit bunches of oil palm). Increasing these Qmax values may ascribe to increasing functional groups of the RMS with OM application. The results prove the importance of OM in controlling the sorption of Fe from AMD onto soils.

Abstract

Coal fly ash, resulted from coal combustion in power plants, with relatively high amounts of aluminium, iron, calcium, and magnesium oxides may modify the sorption capacity of soils. A batch experiment was conducted to examine the capacity of reclaimed mining soils (RMS) to adsorb organic carbon (OC) in response to coal fly ash application. Extraction of dissolved OC was carried out from dried albizia shoot residue and reacted with the RMS at dissolved OC concentrations varying from 0 to 175 mg C L-1 at pH 5.5. The results showed that the sorption capacity of the RMS for OC increased significantly with coal fly ash application, which may relate to increasing the contents exchangeable Ca and Mg, dithionite- and oxalate-extractable aluminium and iron, and surface areas of soils. Desorption experiment indicated that only 5-23% of the OC initially sorbed onto soil-coal fly ash interactions was freed using a single extraction step, suggesting that most of the OC is strongly sorbed to the mineral surfaces. Results of the study indicate an important role of fly ash in increasing OC sorption capacity of soils and reducing the percentage of OC sorption from the RMS-coal fly ash association.

Abstract

Red Yellow Podsolic soil is one type of land that is widespread in Indonesia and can be developed as agricultural or plantation land. Problems that exist in Red Yellow Podsolic soil include low organic matter, infiltration and slow pre-labeling, low porosity which makes the soil tend to be solid, acidic pH, high Al and Fe content and phosphorus deficiency (P). Solid waste (sludge) from a palm oil mill is a suspended sediment from liquid waste and microorganisms from the Wastewater Treatment Plant (WWTP), which can improve soil chemical properties. This study aims to determine the effect application of sludge waste from palm oil mills on decreasing Al-dd and increasing pH in Red Yellow Podsolic soil. Conduct this research in July to August 2019 at the Greenhouse of the Department of Agroecotechnology, Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru, South Borneo. The method used is a completely randomized design (CRD) of one factor, the observed factor is the sludge of the palm oil mill which consists of 5 levels of treatment, repeated 4 times so as to obtain 20 experimental units, namely: S0 control, S1 15 tons / ha (5.55 g / polybag), S2 25 tons / ha (9.26 g / polybag), S3 35 tons / ha (12.96 g / polybag) and S4 45 tons / ha (16.66 g / polybag). The results showed that the application of oil palm sludge solid sludge on the soil chemical properties of Red Yellow Podsolic soil significantly affected the increase in pH, P-available and CEC and reduced Al-dd.

Abstract

The use of fly ash as a material for amelioration has been applied in some countries. Fly ash is amorphous compound of silicate-aluminum-iron that contains essential nutrients for plants. Fly ash has a pH of about 8.5 and has chemical properties that can be used as a source of neutralizing acidity in the soil. This study aims to determine the effect of fly ash as a soil ameliorant of soil on dry land and paddy soil in Kalimantan Selatan . Soil samples on dry land were taken from Sungai Riam, Tanah Laut Regency. Soil samples on paddy soils were taken from Sungai Rangas, Banjar Regency. Six kilograms of each soil samples placed on 8-L pots. Fly ash is added to each pot with a dose of 0, 25, 50 and 75 tons ha-1. All treatments were made in four replicates using completely randomized design. Data were collected for soil pH, total-N, total-K, total-P, and cation exchange capacity. The results showed that only the soil pH and soil CEC significantly affected by the addition of fly ash. Application of fly ash by the number 50 - 75 tons per hectare compare 25 tons per ha does not provide a significantly difference to pH and CEC

Abstract

Forest and land fires were national and international disasters that caused crucial environmental problems and were a local and global concern. This research was conducted to determine the factors that affected forest and land fires in the media frame for future disaster mitigation in addition to the existing restoration efforts such as rewetting, revegetation, and community economic revitalization to minimize its impact. Data were collected from 2012 to 2021 through the framing method and analyzed using content analysis. The results showed that the factors affecting forest and land fires from September 2019 to June 2021 were associated with human activity and natural events. The dominant human activities were land preparation for agriculture and settlements, illegal logging, and lack of public awareness. Meanwhile, the natural factors were the dry season, lightning strikes, and areas with less intensive management, such as non-residential areas.
