Abstract

The infrastructure project has many lies on the mudrock foundation. Some reports in Hambalang, West Java, Indonesia, state the engineering problem related to landslides and foundation failure due to mudrock material's existence. The mudrock originated from Jatiluhur Formation. The problem is also present in slope stability, such as surface erosion and landslide on the many slopes. Landslide material from mudrock material has easily broken into smaller fragments. This research used the wet-dry cycle to evaluate mudrock's durability to weathering on a laboratory scale. The preparation of the test samples in the form of intact rock with a weight of 450-550 grams and then open exposure under sun dry was conducted. The sample was then immersed in water for 24 hours. ISRM physical properties were conducted and correlated with statistical analyses to determine factors affecting the mudrock's durability. From the index of durability, mudrock in Jatiluhur Formation in this research area had various degrees of disintegration. The siltstone samples remained intact until the 15th cycle, unlike shale and claystone samples had expressed low durability and rapid disintegration rate. A series of investigation durability characteristics of mudrock in this study can be applied to other samples and formations that are quantitively and qualitatively.

Abstract

Mercury (Hg) is commonly utilized in artisanal gold mining on Buru Island; the Hg-contaminated tailing possibly contaminates the agricultural land nearby. In general, tailings contain very low organic carbon and plant nutrients but are high in mercury and have extreme soil acidity. The objective of this study was to observe the growth of various legume cover crops (LCC) and the change of Hg in tailing inoculated with Azotobacter-Trichoderma. The field trial was conducted on Buru Island of Maluku by using a split-plot design with three replications. The main plot was LCC species, composed of Centrosema pubescens (CP), Mucuna sp. (MC), and Crotalaria sp. (CR); the subplots were microbial inoculants composed of two formulations of Azotobacter-Trochoderma inoculants. The results showed that the Mucuna sp. and consortia Azotobacter-Trichoderma (2:1) had the highest survival rate in the tailings and Hg uptake by 8.83 mg kg-1 per plant. Consortia Azotobacter-Trichoderma inoculant with the composition of 2:1 (v:v) was able to increase soil pH, total bacterial population, LCC biomass, and Hg uptake by LCC plants. The highest Hg removal effectivity was observed in the plot treated with Crotalaria sp. and in a plot with Azotobacter-Trichoderma (2:1), which was 34.0% and 33.6%, respectively.

Abstract

Batanghari River is the primary source of water for the people of Jambi. Batanghari River’s condition nowadays is worrying because its color is no longer clear. This research focused on determining the content of heavy metals in the Batanghari River's water and sediment. The conducted analysis is an ICP-MS analysis to determine the level of heavy metal (Cu, Cr, Co, Cd, Hg), and an enrichment factor calculation is conducted to determine the source of pollution. The enrichment factor value from the Batanghari River sediment sample declined with the following sequence Cd>Hg>Cu>Cr>Co, in 10 pinpoint locations. These indicate a high degree of anthropogenic activities along the Batanghari River which become the source of heavy metals entering the Batanghari River. The average concentration of heavy metals in the Batanghari River showed that the metal concentrations of Cd, Cu, and Hg are higher than the quality standards that have been set, whereas the metal concentrations of Cr and Co are still by the quality standards that have been set in PP 22 the year 2021.

Abstract

Land use changes become a problem that contributes to the decline in the watershed function and performance. Bedadung watershed divides Jember Regency, which has upstream from Mount Raung and a downstream Indonesian Ocean. During the last ten years in Jember, there has been a flood from the overflow of the Bedadung river, which is unable to accommodate water from upstream. It is alleged that the cause of flooding in upstream of the Bedadung watershed is land cover and land capability that has changed. The purpose of this study was to assess land use changes using a composite approach to Landsat 8 imagery and land capability index for the upstream of the Bedadung watershed. The results showed that land cover of the Kesambi sub-watershed during 1995-2020, forest decreased by 34.74%, settlements and open land decreased by 47.25%, dry land increased by 120%, while plantations and rainfed rice fields were fixed. The decrease in forest area can disrupt the water cycle, thereby increasing runoff volume and water discharge, causing flooding downstream of the Bedadung watershed and upstream of the Bedadung watershed. Land capability evaluation of the upstream of Kesambi sub-watershed, area of Bedadung watershed was mostly in class III, covering 5782.9 hectares (85.53%), class IV covering 214.8 hectares (3.18%), class VI covering 379.7 hectares (5.62%), and class VII covering 383.9 hectares (5.68%) with limiting factors of effective soil depth, land slope/slope, erosion sensitivity, and drainage. Areas with class III land capability covering land mapping units 1, 2, 3, 6, and 7 can be utilized as agricultural with good conservation technology, while land mapping units 4.5, and 8 are only capable for forest areas.

Abstract

The exploitation of natural resources remains a common practice in many countries to stimulate economic growth, and coal is the most commonly exploited resource. However, the mining process often causes environmental disturbance. Therefore, this research was conducted to analyze the ideal implementation of coal mine reclamation in Indonesia. In the post-mining area, the land is often arid, with voids that are prone to flood and erosion. The reclamation of this area is carried out by returning topsoil, adding organic material, and planting cover crops and fast-growing species. When the topographical conditions have steep slopes, scrap engineering is often added to hills up to a maximum height of 8 meters, trimming the slope with a maximum remaining slope of 35 degrees and making drainage channels with a width of more than 3 meters, a depth of more than 2 meters, and an edge slope of 2-5 percent. Approximately 70.59% of reclamation programs in Indonesia are aimed at reforesting mining areas into secondary forests because they were previously a forest ecosystem. The types of reclamation that had been carried out but were still uncommon included aquaculture, urban forests, parks playground, sports park, cattle farms, and fauna conservation ecotourism. A new approach to reclamation, such as eco-habitat, is important to obtain optimal social, economic, and ecological benefits. This approach involves optimizing sources of livelihood based on area rezoning according to the level of interference, revegetation of plants involving the community, and revitalization of sources of community livelihood, specifically environmental restoration with plant species as sources of food, nutrition, minerals, income, and non-timber forest products. Therefore, the reclamation program should be carried out through a collaborative partnership between companies, local communities, academics, technical ministries, and the media.

Abstract

In Algeria, solid waste management (SWM) is considered a major problem; most of this waste is dumped in landfills without any control. The Algerian authorities have developed a national strategy for the integrated management of urban solid waste by 2035 by working on the implementation, development and equipping of technical landfill centers (TLC). Therefore, the aim of this study was to help local authorities in choosing the optimal locations for the completion of the proposed TLC between municipalities. This research used a combination of the multi-criteria decision aid (MCDA) and geographic information systems (GIS). It combines two aggregation methods: Linear Combination of Weights (WCL) and Criteria Weighting. The analytical hierarchy process (AHP) pair-wise comparison method was applied for assigning weights to the 11 criteria that were divided into environmental, social, and economic criteria according to previous studies in the field and the characteristics of the HODNA area. The results showed that 22.56% is the most suitable location for a landfill site, especially on the southeastern side, while 20.70% was suitable and 18.40% was moderately suitable. Finally, the process of assessing the spatial suitability of public emptying sites based on the results obtained in the final digital map,4.76% of the landfill sites are located in inappropriate areas, 14.29% are located in less suitable areas, 33.33% are located in suitable areas, 33.33% are located in moderately suitable areas and 14.29% are located in very suitable areas.

Abstract

Artisanal gold miners usually dispose of gold mine tailings in storage ponds or agricultural land used for farming. However, the gold mine tailings still contain heavy metals such as cadmium, copper, lead, and zinc and can lead to bioaccumulation in food chains. This study investigated the influence of composted cow manure as organic fertilizer on heavy metals (Cd, Cu, Pb and Zn) content in sweet potatoes grown on soil contaminated by gold mine tailing. The MZ119 clone sweet potato plants were grown on soils added with mixtures of gold mine tailings at ratios of 0% (control), 30%, 50%, 70%, and 100% (w/w), and composted cow manure (0, 250, 500, and 750 g/10 kg of soil). The results showed that the higher the ratio of gold mine tailings to the soil, the higher the accumulation of metals in sweet potatoes. According to the translocation factor (TF) value, heavy metals (Cd, Cu, Pb and Zn) accumulated higher in the shoots than in the roots of sweet potatoes. Accumulation of heavy metals in sweet potato occurred in the following order: Zn>Cu>Pb>Cd. This study recommends that sweet potatoes could be used for the phytoremediation of heavy metals (Cd, Cu, Pb and Zn) in polluted soils, but the plants may not be used for consumption.

Abstract

Upstream Bali has tourist destinations with beautiful natural panoramas such as mountains, forest areas, and lakes. Characteristics of the area with steep slopes, high rainfall, and altitude above 1,500 masl. The area is inseparable from the threat of disasters, such as landslides, especially in the Baturiti District. This area often experiences landslides but has not been mapped spatially. Mitigation efforts are needed to minimize the impact of landslides. This study aimed to determine the potential for landslides and their distribution in different periods, namely 2000, 2010, and 2020. The scoring method considers four parameters: rainfall, slope, soil type, and vegetation density, using ArcGIS 10.8 Apps. Parameters extracted from remote sensing data include Landsat with ETM+ and OLI sensors, rainfall from the CHIRPS satellite, and slopes from DEMNAS. Geographic Information System (GIS) data includes soil types. Another role of GIS is to quantify raster data to build a landslide potential prediction model. Baturiti Subdistrict has a low to high potential for landslides, which are administratively distributed in Candikuning, Baturiti, Antapan, Batunya, and Bangli villages. The landslide potential in the high category in 2000, 2010, and 2020 respectively, is 70.12 ha (1%), 597.05 ha (5%), and 39.12 ha (1%). Based on the findings of this study, the leading cause of landslides is high rainfall followed by reduced vegetation density. Other factors include steep slopes (>45%) and soil types of Andosol and Regosol.

Abstract

Forest rehabilitation of Timor Island's dryland ecosystems using eucalyptus plants plays an important role in improving land cover but also in mitigating climate change and providing an alternative renewable energy source. The aim of this study is to explore the enormous energy storage potential of eucalyptus plants for commercial purposes using a high spatial resolution remote sensing approach. The Pléiades satellite imagery acquired on 10/09/2021 covering ca. 27 ha study area managed by Timor Tengah Selatan Forest Management Unit was used to identify the density of eucalyptus plants using Normalized Difference Vegetation Index (NDVI) values greater than 0.699. The density of eucalyptus plants is classified into low, moderate, and high tree density with NDVI values greater than 0.699 to 0.765, greater than 0.765 to 0.833, and greater than 0.833 to 0.901, respectively. The total potential energy production of the study area was estimated using a combination of assumed eucalyptus tree density, the calculated area of each density, and the average energy storage of individual trees. The results showed that the density of eucalyptus trees was classified as low, moderate, and high, with coverage areas of 6.8 ha, 12.9 ha, and 3.0 ha, respectively. The potential energy production of low, moderate, and high density approaches 1,103,432.33 MJ; 5,522,999.19 MJ; and 2,120,715.04 MJ, respectively, with a total estimated energy storage of 8,747,146.57 MJ. This obtained number of potential energy estimations indicates that forest rehabilitation of dryland ecosystems through eucalyptus plantations has a promising future as an alternative renewable energy source.
