Abstract

The Lantung area is one of the places on Sumbawa Island with a large gold deposit. One of the activities of the Lantung people that has the potential to damage the environment is separating gold from mercury. This study aimed to examine the activity of the gold laundering process, and the level of contamination of groundwater and river water due to gold processing from amalgamation by mercury (Hg+) waste. In this study, sampling was carried out for each location, namely two samples of wastewater, six samples of river water, and two samples of groundwater, which were then tested in the laboratory on the parameters of mercury and TSS. At the same time, pH was measured in the field. Furthermore, from the survey results, it was found that the use of mercury was ±150-250 mL at each gold processing location. The results showed that all samples from wastewater (tailings), groundwater and river water were contaminated with mercury with levels exceeding the acceptable quality standards. Furthermore, the status of water quality using the Pollution Index (IP) method shows that wastewater is light to moderately polluted, groundwater is lightly polluted, and river water is also lightly to moderately polluted.

Abstract

Marble is the most important natural material because of its structural features and its long durability. It is mined at operated quarries on hill slopes. The original landform is permanently altered, and vegetation cover is destroyed. Another important feature of marble quarries is the large amount of waste materials released during the quarrying process. In the last decades, together with the visible effects of global warming and climate change, fresh water resources are rapidly depleted and polluted due to careless land use. Quarrying operations are among the most important stakeholders of this process. Environmental effects of quarry activities depend on the location of the site in the landscape, the vertical and horizontal dimensions of the excavation, the methods used to excavate the marble, and the formation of the geological structure. Furthermore, the region's seismicity, microclimate conditions, ecological condition, and surface and groundwater conditions are all factors influencing environmental degradation. Additionally, numerous serious environmental impacts associated with quarrying activities near the site, such as visual pollution, water, dust, noise, air pollution, vibration, land subsidence, and landslides, will cause health issues and unpredictable biodiversity loss. Quarrying operations have the potential to impact pre-existing ecosystems, including groundwater depletion, loss of fertile topsoil, forest degradation, and human health. This article aims to draw attention to various serious environmental impacts, health problems and biodiversity loss resulting from quarrying operations in Burdur Lake Basin.

Abstract

Planting media is an important factor affecting coffee nurseries. Farmers in Wanagiri Village have problems in coffee cultivation because they have soil with a slightly acidic pH. This affects the availability of phosphorus (P) and potassium (K) in the soil. P and potassium K solubilizing fungi can be used to increase the availability of P and K in the soil. This study aimed to analyze the viability of Aspergillus costaricaensis fungi on coffee husk carriers and the effect of A. costaricaensis biofertilizer on planting medium and the growth of Arabica coffee seedlings. The method consisted of the preparation carrier material, viability test of A. costaricaensis on coffee husk carrier, and test of the effect of A. costaricaensis on the planting medium and growth of arabica coffee seedlings. There were four fertilization treatments, i.e., P1 (organic fertilizer), P2 (100% NPK), P3 (organic fertilizer + biofertilizer), and P4 (organic fertilizer + biofertilizer + 50% NPK). Coffee husk carrier material maintained the viability of A. costaricaensis during the nine weeks of storage. The number of populations that could be maintained was log 7.67 (4.7 x 107 CFU g-1). The application of biofertilizer combined with organic fertilizers (P3) increased soil pH to 7.13, and it could potentially reduce the use of NPK fertilizer. Based on the observed growth parameters, it was shown that the treatment of biofertilizers combined with organic fertilizers increased the growth parameters of plant height and stem circumference of Arabica coffee seedlings.

Abstract

Ultisols have considerable potential in developing agricultural cultivation, but in their management, they face several obstacles, including physical properties that do not adequately support plant growth. The low content of soil organic matter causes poor soil physical properties. Low organic matter content leads to low soil aggregate stability, obstructing pore distribution and infiltration so the soil can easily become compacted. This study aimed to observe the changes in some physical properties of the soil due to the application of cow manure and Gliricidia sepium pruning compost and its effect on the yield of soybean plants. This study used a randomized block design with five treatments, namely, K0 (without cow manure-Gliricidia compost), K1 (5 t ha-1cow manure-Gliricidia compost), K2 (10 t ha-1cow manure-Gliricidia compost), K3 (15 t ha-1cow manure-Gliricidia compost), and K4 (20 t ha-1cow manure-Gliricidia compost). The results showed that the 15 t ha-1 cow manure-Gliricidia compost was the best dose in improving the total pore space and penetration resistance of the soil studied. The application of 15 t ha-1cow manure-Gliricidia compost significantly increased soybean yield, reaching 2.97 t ha-1.

Abstract

Rivers on Java Island are one of the water supply sources to meet the surrounding population's water needs. However, only large, high-priority rivers underwent a comprehensive water quality assessment. Rivers that aren't a priority are rarely examined, such as sub-watersheds in Kuntulan, Rejoso. Upper Serayu, Gajahwong, and Glondong. The surrounding community utilizes these five watersheds for irrigation, industry, and domestic. Hence, analyzing the water quality index in the five watersheds during the dry season is necessary. The method used in this research is a comparison of the water quality results between the standards of the Indonesian government and WHO, as well as a comparison of the Water Quality Index (WQI) and Pollution Index (PIj). The method often used in Indonesia is PIj, while WQI is more global and hardly used. The difference in the two ways is expected to provide variations in the water quality index. The water quality parameters were pH, TDS, TSS, COD, PO43-, NO3-, Total Coliform, Temperature, and EC. Comparing water quality with water quality standards in the five watersheds shows that several samples exceed the standard. WQI result shows that all river water in the five watersheds belongs to the excellent classification. A different result from the PIj index shows that the five watersheds were dominantly moderately polluted, with several samples considered polluted and extremely polluted. Differences in the index formula and water quality standards cause these different results. The results of the analysis show that the PIj index is more representative than the WQI as the PIj index shows the suitability of the classification comparison of water quality values with water quality standards compared to WQI.

Abstract

Landslides are a recurring phenomenon that disrupts the natural environment and causes yearly property damage, economic losses, and fatalities. The damage is expected to increase due to deforestation rates, population growth, agriculture, slope-building infrastructure expansion, and global climate change. This study assesses the susceptibility to landslides through Weight of Evidence (WoE) and Frequency Ratio (FR) methods in the Temanggung Regency, Central Java Province, Indonesia, that located on the slopes of two active volcanoes. Initially, a landslide record and the input parameters of the landslide controlling factors were prepared from field surveys, remote sensing data, and secondary data and processed by a geographic information system (GIS). Six landslide parameters in thematic layer maps were selected to develop landslide susceptibility: slope, lithology type, geological structure density, land cover, and rainfall. According to the WoE and FR models, a landslide susceptibility zoning map was classified into four landslide-prone zones from low to very high. Finally, the success and predictive rate curves method confirmed the landslide susceptibility maps to check the model accuracy. The results showed that the landslide susceptibility map using the WoE method had better accuracy than the FR method, with a success rate of 78.48% and a prediction rate of 81.1%. In comparison, the FR method was 74.53% for the success rate and 78.48% for the prediction rate. These landslide susceptibility maps can be used as a guideline to develop land-use planning and landslide disaster mitigation.

Abstract

Landslides are one of the crucial problems that have an impact on land degradation and human life. This study aimed to develop vulnerability maps using ANN to mitigate land degradation in the Bromo Tengger Semeru with the extending area of Universal Transverse Mercator (UTM) Coordinate System Top 91277639, Bottom 911569, Left 692860, and Right 706860. The method applied the Artificial Neural Network (ANN) model using RStudio machine learning. Landslides were mapped using Sentinel Image and Orthomozaic photo interpretation from data acquisition using Unmanned Aerial Vehicle (UAV). The landslide control factor data was obtained through DEMNAS (National Digital Elevation Model) with a spatial resolution of 8 meters. Data normalisation was conducted using the Mix-Max method before it was processed using RStudio. The landslide existing for ANN workflow was processed using the Bioclim model. The results showed landslide susceptibility was categorised into four classes i.e., low susceptibility (29.83%), which was spatially spread on most in the lower slopes, moderate susceptibility (3.11%), high susceptibility (2.99%), and very high susceptibility (15.94) which is scattered on the upper slope to the middle slope of the watershed. The most significant factor influencing the landslide is the topography factor, with a Relative Importance (RI) value of 0.86; the hydrological factor, with an RI of 0.833 and the surface feature, with an RI of 0.355. The results of the landslide susceptibility model are very proper for land degradation mitigation strategies. It has high accuracy through an Area Under Curve (AUC) of 0.965 and a Precision Recall Curve (PRC) of 0.976.

Abstract

Rice grains produced in the conventional system are a prime source of heavy metal exposure in the human body leading to various health problems. The objective of this study was to assess heavy metals concentration in soil and rice grain under the conventional rice farming system in Banyumas, Indonesia, the pollution index, and the bioaccumulation factor. There were thirty-seven samples collected based on soil type, elevation, and irrigation system. The heavy metals level in soil ranged from 2.7 to 39.92 ppm of Pb, 0.11 to 3.01 ppm of Cd, and 4.79 to 61.32 ppm of Cr. Pb and Cr accumulation levels were below the maximum permissible concentration (MPC). A different result in Cd exceeded the MPC in 56.75% of sampling sites. Rice grain showed a high accumulation in Pb (6.85 ppm) and Cr (5.73 ppm) that exceeds the maximum standard. Cd exceeded 24.32% of sampling sites with an average of 0.54 ppm. The Pollution Index (PI) was medium in Cd and low in Pb and Cr. The Bioaccumulation Factor (BAF) of heavy metals in rice was Cd>Pb>Cr with averages of 0.64, 0.53, and 0.30, respectively. A high correlation resulted in Pb and Cd in soils and rice grains. Remediation is must done to reduce the heavy metals accumulation in soils and rice grains for environmental and health safety to prevent further contamination.

Abstract

Archipelago areas have high marine tourism resource potential, so they are often exploited for tourism needs. The characteristics of the Labuan Bajo region in the form of islands with geomorphological conditions in the form of hills have the potential to reduce the carrying capacity of the environment. Regional development in Labuan Bajo, classified as a semi-arid area for tourism purposes, can potentially cause a clean water crisis. This study aimed to analyze the environmental carrying capacity related to water availability to support the development of the Labuan Bajo region to become a super-priority tourism destination. The research method used is quantitative in the form of spatial analysis, literature studies, and water-carrying capacity analysis based on the Decree of the Minister of Environment and Forestry No. 297 of 2019. The research data were obtained from field observations and government agencies. The results show that the carrying capacity of water in 56.87% of the area in West Manggarai Regency has a deficit status. Most areas experiencing a deficit are on the mainland of Flores Island, especially in the urban area of Labuan Bajo. This is due to low rainfall, low soil ability to absorb water, and high anthropogenic activity from both local residents and tourism activities. In addition, the content of salinity, detergent, and BOD (biological oxygen demand) in groundwater samples in the urban area of Labuan Bajo has exceeded the water quality standard threshold. The results of this study can be considered for policy directions related to land use for regional development in semi-arid island areas.

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.
