Land degraded due to over-exploitation is overgrown by Imperata cylindrica, which often causes fires in the dry season. This study aims to determine the species that occur in the secondary succession of Imperata grassland vegetation to assess soil fertility and differences in carbon stocks in various types of vegetation cover on the beach of Marsegu raised coral island. The measurement and calculation of carbon stocks used the Indonesian National Standard 7724:2011 with slight modifications in certain parts. The non-destructive method for calculating the above-ground and below-ground biomass used an allometric and the destructive method was carried out for understory and litter while the carbon content of the soil was taken compositely from several plots and layers and then analyzed in the laboratory. The results showed that the species that can grow and coexist with Imperata cylindrica is Timonius timon. In the final stage of the loss of Imperata cylindrica, the beach forest area was dominated by Terminalia catappa, Sterculia ceramica, and Cassia fistula. The soil's nutrient content of total N, P2O5 (available P) and cation exchange capacity (CEC) is low, with a very high sand texture percentage of 91-93%, which affects soil fertility. A comparison of total carbon stocks between differences in vegetation cover is the Imperata grassland area of 129.955 t/ha, the rehabilitation area is 82.920 t/ha, and the Terminalia vegetation is area 137.977 t/ha.","PeriodicalId":36513,"journal":{"name":"Journal of Degraded and Mining Lands Management","volume":"61 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139127262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has past volcano eruption history since 1911 up to date. Specifically, Plawangan Hill is a part of the TNGM recently designated as Geo-heritage and has experienced volcano eruption indirectly and directly. Additionally, since the Indonesian government designates Plawangan Hill as a Geological Heritage (Geo-Heritage) location, it is crucial to determine its geological features and how they relate to the development of the vegetation there as the studyâ€™s objectives. A field survey and a soil laboratory examination were conducted to obtain the data. As a result, Plawangan Hillâ€™s DEM was classified from very low to very high classes, while the DSM was categorized from flat to very steep slopes. Further, the results demonstrated that the pH of theÂ soil was typically somewhat acidic (5.93â€“6.54). While the soilâ€™s nitrogen content was found to be low to medium, both phosphorusÂ and potassium levels were typically very low. The carbon-nitrogen ratio wasÂ generally categorized into the medium, while the organic C ranged from low to medium (1.44% to 3.22%). The soilâ€™s N total, K total, organic matter, carbon content, and C-N ratio increased by the erupted material age. Additionally, it was discovered that the vegetation growth was excellent in indirect (IA) and directly affected (DA) conditions, as indicated by their diameter at breast height (Dbh) and height (H). The correlationÂ between soil characteristics andÂ vegetationÂ growth differed in indirectly affected (IA) and directly affected (DA) areas. As a result, the study found that volcanic materials significantly contributed toÂ Plawangan Hillâ€™s soil characteristics and vegetation growth. Furthermore, this studyâ€™s findings were highly beneficial because they were one of the primary explanations for why Plawangan Hill was designated a Geo-heritage site.","PeriodicalId":36513,"journal":{"name":"Journal of Degraded and Mining Lands Management","volume":"28 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139127696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methods used in this study area included a study of weathered tuff profile characteristics, weathered tuff infiltration testing and residual soil (RS) determination of weathered tuff water content and residual soil, and testing of shear strength of weathered tuff and residual soil. This research used aspects of engineering geology, including shear strength, water content, and infiltration rate, as well as rock weathering grade to determine the slip surface in tuff to determine the volume of landslide material. The results showed that the tuff profile consisted of four grades, namely moderately weathered tuff (MW), highly weathered tuff (HW), completely weathered tuff (CW), and soil residual (RS). The rate of tuff infiltration increases with increasing weathering grade. The water content is more significant with the high degree of weathering of tuff. At the same time, the shear strength decreases with high weathering. Therefore, the research area is prone to landslide events. The slip surface is in a layer of moderately weathered tuff rock (MW), and those that experience landslides are highly weathered tuff rock (HW), completely weathered (CW), and residual soil (RS).","PeriodicalId":36513,"journal":{"name":"Journal of Degraded and Mining Lands Management","volume":"52 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139128022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five heavy metals were evaluated in this study, including nickel (Ni), cadmium (Cd), chromium (Cr), copper (Cu), and lead (Pb). Roadside dust pollution in urban Ramadi streets was assessed using the ecological risk index (RI). Hazard quotient (HQ) and hazard index (HI) calculations were performed for all three exposure pathways (dermal contact, ingestion, and inhalation). The results showed that copper (mean = 49.520 mg/kg) and chromium (mean = 34.742 mg/kg) had the highest heavy metal concentrations, followed by nickel, lead, and cadmium.

The investigation encompasses an analysis of total mercury levels in soil samples obtained from Sukamenang, Muara Batang Empu, and Terusan Villages. As a comparative reference point devoid of gold mining activities, the neighboring Muara Lakitan Village was selected. The obtained results indicate a moderate to strong contamination level across the 30 sampled locations based on the Geoaccumulation Index (Igeo), with an average Igeo value of 2.6. Furthermore, Pollution Load Index (PLI) and Contamination Factor (CF) values demonstrate high contamination. Conversely, analysis of river water samples from 30 stations along the Rupit River reveals that most of the samples comply with quality standards (<0.0005 mg/L), with an average value at 0.000322 mg/L; only four stations exhibit total Hg concentrations surpassing regulatory thresholds. All soil and river water samples from the control area (10 stations) exhibited no signs of pollution.

Soil amendments are needed to reduce heavy metal content in contaminated soil to minimize heavy metals in plants. Biochar that contains high organic carbon material and is highly resistant to decomposition is claimed to inhibit and reduce the content of heavy metals in soil and plants. Banana wastes containing cellulose and lignin are considered good as biochar raw materials. This research that aimed to observe the ability of banana waste biochar to reduce heavy metals in soil taken from Subak Kerdung, Bali, was conducted in a greenhouse using maize plants as control plants. The treatments tested consisted of two factors. The first factor was the type of banana waste as biochar-making material consisting of banana stem biochar, banana peel biochar, banana fruit bunch biochar, and mixed biochar (banana stem + banana peel + banana fruit bunch). The second factor was the biochar dosage, which consists of four contents, namely 0 t/ha, 5 t/ha, 10 t/ha, and 15 t/ha. All treatment combinations were arranged in a two-factor, randomized block design with three replications. The results showed that mixed biochar (banana stem + banana peel + banana fruit bunch) effectively reduced Pb and Cu in maize plants. In contrast, banana peel biochar could optimally reduce Cd content in soil and its content in plants. Based on the dose, 15 t/ha of mixed biochar reduced Pb and Cd contents, while 10 t/ha of mixed biochar reduced Cu content.","PeriodicalId":36513,"journal":{"name":"Journal of Degraded and Mining Lands Management","volume":"41 39","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139125591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary data collection method uses a total sampling of 80 miners operating in the research area. Consumer data uses a field survey method with 8 hours of observation per day. Saddang River sand mining provides great socio-economic value and environmental impact, directly or indirectly. This significant socio-economic value and impact, if not accompanied by good management, can result in over-exploitation, which impacts the physical and ecological damage of the Saddang River. On the other hand, the high rate of sedimentation from upstream of the Saddang River results in shallowing, so sand mining activities help normalize the Saddang River.
