Tarakan, Kalimantan Timur

TAHUN

2012


Project Background

Government Regulation Number 7 Year 2014 requires all companies including coal and ore mining to perform post mining reclamation. This regulation explains that the company must restore post mining lands according to their functions and uses. The type of soil to be reclaimed by PT Mandiri Inti Perkasa is high in clay and acidity contents, and thus is difficult to be used as a planting medium

Total Area: 2 ha

Duration of Work: 1 year

The Challenge

Overburden, bulk density caused by heavy equipment

High acidity, pH < 4

THE HANDYWORKS

1. Biosimultant Application to restore soil structure

Soil is plowed to help biostimulant restore the soil structure. The biostimulant used is specifically made to rehabilitate post-mining land. Once biosimultant has been applied, soil is saturated with water and allowed to stand for about two weeks while humidity is still maintained.

2. Providing the land with soil nutrients

After the first two-week incubation period, the next step it to apply the biostimulant in the soil as the source of nutrients for plants. Biostimulant is sown, sprayed with water and left out for one month to optimize the process. The biostimulant produced by PT Indmira is made from the fermentation of organic materials by a strain of bacteria that can reduce toxicity. It contains natural ingredients that are environmentally safe.

3. Planting and Revegetation

After the land restoration, revegation commences. Revegation is performed by planting and sowing Legume Cover Crop (LCC), fertilizing three times a month, with monitoring and mantainance.
