Abstract

Nickel is formed through the weathering of ultrabasic or ultramafic rocks originating from oceanic crust which is transferred to the surface of continental crust. This formation process took millions of years, starting when ultramafic rocks were exposed on the earth's surface. Nickel mining plays an important role in the electric vehicle battery industry and economy in Indonesia, but its impact on the environment often results in mined land with unique characteristics that is difficult to reclaim. Ex-mining land often has a Mg/Ca ratio higher than one. In addition, the soil on ex-nickel mining land is usually shallow and hydrophobic, making it difficult to absorb water. Reclamation of ex-mining land is the focus to restore, increase the soil's water absorption capacity and land productivity. With an approach to improving physical, chemical, and biological properties, reclamation technology includes the method of making planting holes measuring 60x60x60 cm, composting organic materials, and using Super Absorbent Polymer (SAP) to increase the soil's water absorption capacity. In this context, reclamation technology is the key to accelerating the successful reclamation of ex-nickel mining land in a sustainable manner and optimizing the utilization of nickel mining resources in Indonesia.

Abstract

The "Dosen Pulang Kampung" (Lecturer Goes Home) program is a community service effort conducted by IPB University aimed at contributing knowledge and technology to rural communities. In this activity, the authors introduced Zeoponic planting media to horticultural farmers in Mojosongo District, Boyolali. Zeoponic, a zeolite-based planting medium, is designed to address the high electrical conductivity (EC) problems in traditional planting media, which often hinder nutrient absorption. With zeolite content, Zeoponic has a high cation exchange capacity (CEC), maintaining EC and moisture stability, thus supporting optimal seedling growth. The activity was carried out in three stages: a theoretical session explaining the concept and benefits of the medium, a demonstration of its preparation directly by the farmers, and an evaluation through discussions as well as pre-test and post-test to assess participants’ knowledge improvement. A total of 30 farmers from local farmer groups in Mojosongo participated in the program. Results showed that Zeoponic could improve the quality of horticultural plant seedlings and has great potential for adoption by local farmers. This program is expected to support sustainable agriculture and enhance the welfare of farmers.
