Abstract

Mining activities often leave behind degraded land requiring restoration and sustainable utilization. This study aims to (1) analyze the suitability of post-mining land for agriculture, (2) assess the socioeconomic conditions of surrounding communities, and (3) evaluate sustainability factors influencing post-mining land use. A land evaluation was conducted using a matching system, while socioeconomic data were collected through purposive sampling interviews across four post-mining sites in East Kalimantan, Indonesia. The land suitability analysis identified three viable agricultural uses: rice cultivation (342.94 ha), corn production (209.51 ha), and pasture-raised cattle grazing (377.81 ha), with distribution across sites LP1, LP2, LP3, and LP4. The sustainability of each site was assessed across five dimensions: ecological, economic, social, legal, and infrastructure, using composite sustainability indices. Results showed varying sustainability levels: ecological (59.37, moderately sustainable), economic (80.35, highly sustainable), social (70.43, fairly sustainable), legal (57.42, moderately sustainable), and infrastructure (85.53, highly sustainable). These findings indicate that while economic and infrastructural conditions are favorable for sustainable land use, ecological and legal aspects require targeted improvements. The moderate social sustainability score suggests a need for greater community engagement and benefit-sharing mechanisms. These findings provide actionable insights for improving post-mining land use and promoting sustainable development in East Kalimantan, Indonesia.

Abstract

Brackish water, although often neglected due to its high salinity, represents a strategic water source for coastal communities facing freshwater scarcity. This study addresses a research gap in the utilization of heavily contaminated brackish water in tropical peatland areas of East Kalimantan through an integrated hybrid technology approach that combines local governance and renewable energy. Water samples were collected from two locations in Taddutan Island (RT 7 and RT 8) in December 2023 and analyzed at the accredited DLHK Kutai Kartanegara Environmental Laboratory. Results showed that raw water exhibited salinity of 0.22–4.42‰, total dissolved solids (TDS) of 244.6–4,658.5 mg/L, chemical oxygen demand (COD) of 18.4–46.4 mg/L, and extreme microbiological contamination (Total Coliform reaching 87,320 MPN/100 mL). The local PAMSIMAS unit failed to completely eliminate Total Coliform despite significantly reducing TDS. Based on these findings, a four-stage hybrid treatment system was designed: (1) coagulation-flocculation (alum + KOH), (2) multistage filtration (rapid sand, manganese zeolite, activated carbon), (3) reverse osmosis (RO) using brackish water membrane, and (4) UV disinfection. The system is operated using a 2,500-watt solar photovoltaic system (PLTS) to ensure energy sustainability, while governance by the Village-Owned Enterprise (BUMDes) Mekar Sejati and community Willingness to Pay (WTP) (IDR 50,000–150,000/month) guarantees operational sustainability. The novelty of this research lies in the integration of three pillars: (i) RO hybrid technology with adaptive pretreatment for peatland brackish water, (ii) integration of PLTS as a renewable energy source, and (iii) BUMDes-based governance. This model has high replication potential across hundreds of coastal peatland villages in Indonesia facing similar challenges
