Abstract

Many areas in Central Kalimantan have a lot of small-scale gold mining activities (illegal mining), involved thousands of gold miners. These gold mining activities had caused extensive damage to the landscape, both on land and in waters. This activities carried out aim to; (1) Developing an integrated form of business incubation in agriculture and animal husbandry for gold mining communities in 3 villages in Central Kalimantan; (2) Conduct socialization, training, and assistance to the gold mining community in cultivating chickens intensively, diversifying livestock production, and carrying out integrated agriculture in a sustainable manner; (3) Fostering productive business units from upstream to downstream in integrated agriculture, through the support of infrastructure, purchase of tools and materials, to find prospective market networks through the implementation of post-harvest processing and appropriate marketing strategies. These activities were carried out in 3 (three) villages, namely, Tuwung Village, Sigi Village, and Marang Sub-District, from September to December 2022. The results of the activity showed an increase in the participants' knowledge regarding the dangers of mercury pollution and alternative types of businesses that were more productive and environmentally friendly. The skills of the miners have also increased, in terms of chicken cultivation, maggot cultivation, and post-harvest processing and also marketing. This activity is also able to support the economy of gold miners, which is obtained from the sale of 4 main products, namely chicken products, magot products, agricultural commodities, and livestock manure compost. On average, 60% of miners stated that they were willing to shift their jobs from gold miners to workers in integrated agriculture and animal husbandry.

Abstract

Gold mining uses mercury for the gold extraction process, where the mercury content in the Kahayan watershed reaches 2.996 - 4.687 µg/l and this value exceeds the standard limit for mercury content in water. Bioremediation is one solution to reduce mercury waste pollution. Mercury bioremediation using microorganisms and adsorbents requires appropriate process steps to be effective in eliminating mercury. This study aims to determine the effect of bioremediation stages on the effectiveness of mercury (Hg) elimination in liquid media and to determine the most effective bioremediation steps for mercury (Hg) elimination in liquid media. This study used an experimental method with a nonfactorial completely randomized design consisting of treatments namely control (K), treatment 1 (T1), treatment 2 (T2), treatment 3 (T3), treatment 4 (T4), with 5 (five) times repetition. Analysis of the results of the bioremediation stages using AAS (Atomic Absorption Spectrophotometry). Data were analyzed using the One-way Anova test, LSD test and effectiveness test. The results showed that the bioremediation stage had a significant effect on the effectiveness of mercury (Hg) elimination in liquid media. The most effective bioremediation stage for mercury (Hg) elimination in liquid media is the T3 stage which starts from Mercury Waste→Microalgae→Bacteria→Red Clay→Activated Charcoal, with an effectiveness value of 89.4% in reducing mercury.
