Abstract

Mineral mining activities in Indonesia, especially those conducted in the open pit, to dismantle the hard rock is usually done by blasting. Blasting process is often conducted over the protests of the residents of the villages around the mining area , due to frequent ground shaking (ground vibration ) whose velocity exceeds the threshold value at certain distances from the center of the ground shaking explosions cause damage and discomfort felt by surrounding population . Based on this, the research was conducted to determine the safe distance from the blasting vibration of the ground (ground vibration) and air blast (air blast) criteria based on the value of the safety standards that blasting can be well designed and to determine a safe zone for blasting activities. This study uses data processing BlastMate III / Minimate Plus is recorded into the computer/laptop using software blastware. The recorded data is then analyzed by comparing these data with existing vibration standards. The results of the study on coal blasting vibration will use Standard Quality Decree No. LH. 49 of 1996 . The results showed a safe distance from the blasting vibration ground (ground vibration) in the village of Manggis sub district Kelumpang is as far as 1037.84 meters upstream from the point of explosive or active pit areas with the use of blasting and air blast (air blast) is safe for the environment is at a distance comfort 900 m from the blast point average into the borehole 15 m and average load of 40,000 kg of explosives.

Abstract

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.Key words: fly-ash application; soil ameliorant; heavy metals; sub-optimal low land.

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
