Heavy compaction can occur in agricultural soils due to intensive tillage, where its effects on soil properties have been the focus of many studies. The present study was undertaken to assess whether soil compaction occurs in agricultural soils adopting no-tillage systems and how the link between soil compaction and chemical-biological characteristics could be. A field investigation was carried out in two different locations that have different soil types, Entisol in Maitara Island and Ultisol in Halmahera Island, North Maluku Province. Sixteen undisturbed and disturbed soil samples were collected from each location grown with cassava and taken to the laboratory for analysis. Soil components observed included soil texture, bulk density, particle density, total porosity, soil permeability, soil organic matter (SOM), total nitrogen (N), phosphorous (P) availability, and phosphate-solubilizing bacteria (PSB). The findings revealed linear relationships between soil compaction and sand fraction, SOM, PSB, and available P, but none were found in soil total N. These results confirmed the importance of soil compaction management in food crop agricultural systems, particularly when soil carbon is low, to promote soil health. As the inconsistent correlation of soil compaction and chemical-biological properties was found in these two soil types, further investigation is necessary.</p> Lily Ishak Amiruddin Teapon Reginawanti Hindersah Nurmayulis Nurmayulis Erwin Erwin Tri Mulya Hartati Copyright (c) 2024 Journal of Degraded and Mining Lands Management https://creativecommons.org/licenses/by-nc/4.0 2024-04-01 2024-04-01 11 3 6049 6058 10.15243/jdmlm.2024.113.6049 Study of coastal land change in sand mining activities in Bandar Batauga Village, South Buton Regency, Indonesia https://www.jdmlm.ub.ac.id/index.php/jdmlm/article/view/16508 <p>This research focused on land changes in Bandar Batauga Village, South Buton Regency, Indonesia, related to environmentally damaging sand mining activities. The primary objective of this research was to analyze land evolution in coastal settlement areas vulnerable to disasters, with an emphasis on the impact of sand mining until the year 2050. The research methods encompassed quantitative and qualitative approaches, including coastal change analysis using ArcGIS, in-depth interviews, and statistical methods. The research findings highlighted a significant increase in coastline changes, reaching an erosion area of 511.3 m² in 2022. Projections until 2050 indicate a potential maximum erosion of 1,157.22 m². This research employed the analytic hierarchy process, focusing on social, economic, physical, and biotic environmental aspects to formulate disaster mitigation strategies. However, implementing environmental management policies faces challenges, such as a lack of competence in relevant departments and low awareness among mining permit owners. Therefore, strategic recommendations involve enhancing human resource capacity, strengthening oversight, and providing economic support as critical steps to reduce mining activities.</p> Zulkifli Mappasomba Romiyatno Suleman Copyright (c) 2024 Journal of Degraded and Mining Lands Management https://creativecommons.org/licenses/by-nc/4.0 2024-04-01 2024-04-01 11 3 6059 6069 10.15243/jdmlm.2024.113.6059 Influence of limestone as pre-treatment for sustainable acid mine drainage water quality management in Tanzania https://www.jdmlm.ub.ac.id/index.php/jdmlm/article/view/16509 <p>Acid Mine Drainage (AMD) is a major environmental problem due to low pH, high sulphate content, and dissolved metals. The aim of this study was to investigate the potential of limestone materials for the primary treatment of AMD water. Different doses of limestone were used in this study in the ratio of 0 g/1,000 mL as control, 20 g/1,000 mL, 40 g/1,000 mL, 60 g/1,000 mL, 80 g/1,000 mL, 100 g/1,000 mL, 200 g/100 mL (limestone/AMD) in a batch experiment of 1,500 mL plastic container. The results showed that the pH of AMD water improved to 8.6 at a dose of 100 g/1,000 mL, and the sulphate concentration decreased from 2,277 mg/L to 506 mg/L at a dose of 200 g/1,000 mL. The removal of Fe, Cu, Zn, Mn, and Ni at 200 g/1,000 mL was 99%, 92%, 68%, 96%, and 99%, respectively. The results of this study also showed that the Mn content decreased slowly as the limestone dosage increased. In addition, this study showed that limestone is a good neutralizing agent for increasing the pH of AMD water and reducing sulphate and dissolved metal concentrations. The results of this study indicated that limestone is suitable as a primary treatment agent for AMD water treatment in gold mines in Tanzania.</p> Alexander Marwa Lukuba Ngalya Sweya Copyright (c) 2024 Journal of Degraded and Mining Lands Management https://creativecommons.org/licenses/by-nc/4.0 2024-04-01 2024-04-01 11 3 6009 6015 10.15243/jdmlm.2024.113.6009 Understanding the impact of land use change on urban flood susceptibility mapping assessment: A review https://www.jdmlm.ub.ac.id/index.php/jdmlm/article/view/16504 <p>Over the past few years, numerous urban areas have been identified in floodplains and coastal regions. These areas should be repurposed as water storage zones to enhance surface water infiltration. The escalating demand for land in flat areas adds complexity to the susceptibility of urban areas to flood hazards. The observation focuses on understanding how land use change influences urban flood susceptibility assessment. Several aspects assumed to have a significant relationship with the flood phenomenon include the impact of land use change, environmental health impact, modification of land typology, explanation of urban flooding, appropriate model for flood-prone assessment, current state of research, appropriate steps in decision-making in susceptibility areas, and challenges of the scenario-based flood-prone mapping model in the future. Additionally, the assessment aspect should consider the impact of land degradation resulting from land use change. Integrated measures are necessary to guide future studies aimed at improving ecological quality and restoring environmental health. The availability of free and open-source datasets facilitates conducting studies to support decision-making both locally and regionally.</p> Eggy Arya Giofandi Boedi Tjahjono Latief Mahir Rachman Copyright (c) 2024 Journal of Degraded and Mining Lands Management https://creativecommons.org/licenses/by-nc/4.0 2024-04-01 2024-04-01 11 3 6025 6035 10.15243/jdmlm.2024.113.6025 Removal of heavy metal ions from water using nanocellulose-based membranes derived from macroalgae Chara corallina https://www.jdmlm.ub.ac.id/index.php/jdmlm/article/view/16502 <p><em>Chara corallina</em> is a freshwater macroalgae found in aquatic-terrestrial boundary environments. Their cellulose fibers have a crystallinity and biosynthesis similar to those of terrestrial plants. The algal nanocellulose (NC) was prepared through a series of chemical treatments, including alkaline, bleaching, grinding, and acid hydrolysis. The X-ray diffraction (XRD) crystallinity index of nanocellulose was 85.64%. The cellulose nanocrystals are seen in the form of nanorods, and the specific surface area of the sample of NC found was 5.823 m<sup>2</sup>g<sup>-1</sup>. The study aimed to test the effectiveness of a nanocellulose composite membrane in removing heavy metal ions, specifically cadmium (Cd), nickel (Ni), and lead (Pb) ions, from an aqueous solution. A vacuum filtration unit was used for the experiment, where up to five filter layers of composite membranes were examined for their ability to remove heavy metal ions. The results showed that the highest removal rates of Cd<sup>2+</sup>, Ni<sup>2+</sup>, and Pb<sup>2+</sup> ions were 98.20%, 95.15%, and 93.80%, respectively, when using five layers of membranes of NC with the adsorbent dose set at 20 ppm. Cellulose and its derivatives are essential in sustainable technology for wastewater treatment, as they demonstrate exceptional performance in removing various types of pollutants, including heavy metals, dyes, and other pollutants. Cellulose is preferred due to its low cost, biodegradability, eco-friendliness, and simple surface modification.</p> <p> </p> Yasir Yousif Omar Hassan Ibraheem J.
