Abstract

Population growth in urban areas increases rapidly due to improving economic conditions. However, this growth is not always followed by the addition of public facilities such as clean water facilities and sewage water system networks, especially in developing countries. There are still many people who use on-site sanitation systems that will cause groundwater pollution problems. In addition, many people in urban areas still depend on groundwater for drinking water. The quality of groundwater becomes an essential factor for this purpose. One of the common groundwater problems in urban areas is nitrate concentration. Therefore, this study aimed to determine the potential groundwater contamination, the primary source of nitrate contamination in groundwater, and their influencing factor in the study area. The research method used the Cl/NO3 ratio and Cl/Br ratio to determine the source of nitrate in the study area. The groundwater contamination potential was evaluated based on depth to the groundwater table, sorption capacity above the groundwater table, permeability, groundwater table gradient, and horizontal distance from the contaminant source. In addition, the total of family members, age of the settlement, the distance of the well from the septic tank, and groundwater table depth were correlated with nitrate concentration. The results showed that nitrate levels in the research area generally exceed the maximum drinking water limit by WHO, with the maximum concentration reaching 167 mg/L. The high concentration of nitrate in the groundwater is due to contamination. According to the diagrams of nitrate versus chloride and the Cl/Br ratio analysis, the primary source of groundwater nitrate contamination is a septic tank. The higher family member and age of the settlement have a positive correlation with increasing nitrate concentration. Besides, distance from the septic tank and depth of the groundwater table is negatively correlated with nitrate concentration.

Abstract

Assessment of land damage has been included in several Indonesian government policies, but it tends to have zero dimensions or only one point in the year. This study tried to propose an inter-time assessment of land damage with a land stability index by including the development of knowledge and technology at nickel mining sites in the easternmost part of North Konawe Regency. Orthophoto and Digital Elevation Model (DEM) images from drones in 2020 were taken in a field survey and used as primary data. While the SPOT 5 Imagery in 2014 and National DEM were collected as secondary data. The developed method combining slope, soil, TRI (Terrain Ruggedness Index), and land cover factor has been considered moderately accurate. Applying the method between different periods has produced a temporal land stability index where a positive value means more unstable, zero means unchanged, and a negative value means more stable. The results showed that after six years, the largest area due to nickel mining in the area has not changed much or had zero value. This is because the area tends to remain a natural forest. The more stable area is located in the southern part of the study site. However, the increasingly unstable area is located in the northern part of the study site. If no reclamation action is taken, the potential for further damage will occur.

Abstract

La présente étude a été menée dans le but de contribuer à une meilleure compréhension de l'adaptation des psammo-halophytes à leurs environnements hostiles à travers la détermination de leur statut mycorhizien. Il s'agissait de l'évaluation du statut mycorhizien de Plantago coronopus L. en relation avec les paramètres édaphiques de sa rhizosphère dans une dune du littoral oranais. Des échantillons de sol rhizosphérique et de racines ont été prélevés sur trois sites situés sur les dunes de Bomo-plage, à l'ouest d'Oran. Les paramètres de colonisation mycorhizienne de la plante et les paramètres physico-chimiques du substrat ont été déterminés. Les résultats ont montré que le substrat avait une texture sablo-limoneuse, il était légèrement salin, très pauvre en eau et en nutriments, avec une forte charge de calcaire total et une faible teneur en carbone organique et en azote total. Les racines ont été colonisées par des champignons de type mycorhizes arbusculaires avec une fréquence moyenne élevée (61,34%). Les résultats de l'analyse en composantes principales ont révélé que les paramètres mycorhiziens étaient positivement corrélés avec la salinité du sol, le carbone organique et la matière organique, l'azote total et le limon. Cependant, la corrélation entre les paramètres mycorhiziens et le pH,

Abstract

Many factors cause increasing Pb contamination in soils, including intensive crop production, motor vehicle exhaust gas around agricultural land areas, or irrigation mixed with household. An effort is needed to minimize Pb contamination in soils. This experiment aimed to examine the potential of Crotalaria juncea L. intercropped for minimizing the accumulation of Pb in vegetable crops grown intensively using agrochemicals. The treatments tested were monoculture of Brassica rapa, monoculture of Phaseolus vulgaris, monoculture of C.juncea, intercropping C. juncea with B.rapa, and intercropping C. juncea  with P. vulgaris. Results of the study showed that planting of C. juncea reduced the total dry weight of B.rapa by 33.47% and increased the total dry weight of P. vulgaris by 17.41% compared to monoculture. Intercropping of B rapa or P. vulgaris with C. juncea reduced the total Pb concentration of B. rapa by 45.64%, and that of P. vulgaris by 16.22%. Planting of C. juncea reduced the Pb concentration in B. rapa by 21.23% (Pb 0.89 mg kg-1) and that in P. vulgaris by 76.03% (Pb 0.93 mg    kg-1). Monoculture planting of C.juncea and intercropping of C. juncea with B. rapa or P. vulgaris reduced the concentration of available Pb and total Pb in the soil to not detected value, compared to monoculture planting of B. rapa and P. vulgaris.

Abstract

With limited land availability, the land use and management on the small island must be sustainable. Sulabesi Island, with an area of <2000 km2, makes it one of the small islands in North Maluku and a remote island. This condition makes Sulabesi vulnerable to land loss and faced with adverse threats both environmentally and socio-economically if the allocation of residential places does not manage appropriately. The study aimed to identify the distribution of coastal settlement land with the characteristics of the island landscape, including analyzing its suitability to coastal boundaries and recommending directions for the development of coastal settlements on Sulabesi island. The method of this study used the geographic information system (GIS) to provide a spatial picture with overlaying and buffering techniques. The data analysis used topography, slope, distribution of settlements, and coastlines with collected data sources from government agencies and remote sensing, including field observations. The analysis results showed that the settlements scattered Sulabesi island randomly and separately with linear patterns, clustering, and combinations. The distribution in the island landscape was with a dominant height at 0-200 m and a slope of 0-30% or is a flat-steep plain. Besides that also shows a mismatch of utilization between the residence and the coastal border area, so land use for future settlements can do on the more proportional ground, especially outside the coastal buffer area. The results of this study's analysis can be used for further direction in regional planning and land management on small islands.

Abstract

Sandy loam soils contain low organic carbon and have low ion adsorption capacity. Under certain conditions, the soils contain heavy metals that are harmful to plants. Soil amendments such as biosilica and humic acid from natural sources are expected to increase the soil adsorption capacity to heavy metals. A simulation experiment consisting of two factors was conducted to explore the effectiveness of humic and biosilica, as soil amendments, in adsorbing heavy metals from soils. The first factor was biosilica dose composing 0 t ha-1 (S0), 0.5 t ha-1 (S1), 1 t ha-1 (S2), and 1.5 t ha-1 (S3). The second factor was the humic acid dose composing 0 kg ha-1 (H0), 20 kg ha-1 (H1), 40 kg ha-1 (H2), and 60 kg ha-1 (H3). The humic acid and biosilica were applied to soil contaminated with Pb and Cd. The results showed that the combination of 0.5 t biosilica ha-1 (S1) and 20 kg humic acid ha-1 (H1) significantly increased soil pH, organic C content, cation exchange capacity, and reduced the availability of Pb and Cd at 90 days after treatment. The Pb and Cd contents in plant tissue decreased from roots to grains. Humic acid treatment was more effective in absorbing Pb of 86.89-90.49% and Cd of 71.47-76.33% than other treatments.

Abstract

Determining the oil palm dead roots contribution to total (Rt) and heterotrophic (Rh) respiration as a source of greenhouse gas/GHG emission in tropical peatland is urgently required, as well as predicting their magnitude to cope with difficulties of direct in-situ measurement. This study is designed to simulate the CO2 flux emitted from oil palm dead roots/Rdr in tropical peatland as affected by water content/WC and residence time/RT. The dead oil palm roots were cleaned, treated with control/15, 100, 150, 300, and 450%WC, and then incubated for three months. CO2 flux measurement, C, N, and CN ratio determination were conducted every month. This study demonstrated the importance Rdr among other CO2 emission sources, ranging from 0.05-2.3 Mg CO2 ha-1 year-1 with an average of 0.7 Mg CO2 ha-1 year-1. Rdr contribution for literature Rt and Rh were around 0.3 to 1.3 and 0.9 to 3.5%, respectively. As a product of microbial respiration, Rdr was affected by WC and RT, supported by analysis of variance, linear mixed effect model/REML, and multivariate analysis. 100-150%WC resulting in significant and highest Rdr, whereas the increase (300-450%WC) or decrease (15%WC) would generate lower emission. Rdr culminated in the first month after incubation; meanwhile, it declined in the following months. This study also emphasized non-linear relationships between CO2 flux and other root properties, which can be modeled conveniently using non-linear approach, particularly using polynomial and artificial intelligence-based models. The simulation presented in this study served as an initial attempt to separate Rdr from Rh, as well as to predict CO2 flux with reasonable accuracy and interpretable methods.

Abstract

Over the next years, Indonesia’s traditional gold mining technique (that employs mercury amalgamation) will be gradually replaced by cyanidation as a result of a Presidential Decree that has been recently issued. The cyanide-containing waste resulting from the processing tanks of this new method will be generally sedimented and flow directly into the surrounding small rivers. This study aimed to reduce the impact of cyanide contamination on the environment by using the simple activated carbon that can be produced by artisanal small-scale gold mining (ASGM). Water samples were taken from artificial wastewater as part of three replications. The highest recorded removal of cyanide from sewage was 98.43%, with an equilibrium reached at a fixed adsorbent dosage of 0.05 g over a contact time of 24 hours. Cyanide adsorption was also found to be pH-dependent, with the highest cyanide adsorption occurring at a pH of 8. The adsorption capacity for cyanide was estimated at 12.51 mg g-1 of the adsorbent, and it was considered to function based on a Langmuir isotherm model. The findings of this study confirm that the utilized glass wool in the assessed method can increase the yield of activated carbon, thereby offering a low-cost and effective adsorbent that can be used in order to remove cyanide from ASGM wastewater.

Abstract

 Topsoil in post-mined land generally has a low fertility level. Its availability is not always in sufficient quantities to meet minimal needs for mine reclamation, so substitute materials and ameliorants are needed to increase its quantity and quality. Fine coal and fly ash-bottom ash (FABA) are wastes expected to reduce the demand for topsoil and, at the same time, may improve topsoil quality. This study aimed to examine the application of fine coal as a topsoil substitution and its effect on changes in the chemical properties of topsoil and the growth of jabonv (Anthocephalus chinensis). The study was conducted in a greenhouse with a completely randomized design model with two factors. The first factor was fine coal with four levels of 0, 10, 20, and 50% from the topsoil (w/w), and the second factor was FABA with three levels of 0, 500, 1000 g/15 kg of growing media. The jabon plant was grown for 24 weeks. The results showed that up to 50% fine coal could be used as a topsoil substitution. The interaction of fine coal and FABA increase pH, organic C, total N, cation exchange capacity, available P, base saturation, exchangeable cations, and micronutrients, and reduce the amount of exchangeable Al in the soil. FABA with a dose of 1000 g/15 kg of growing media and 50% fine coal was the best treatment to increase the growth of the jabon plant.

Abstract

The vegetative coverage throughout the world is rapidly changing, which also directly affects the land degradation. Therefore, this study was intended to investigate the vegetation vulnerability analysis triggered by land use/land cover (LULC) dynamics as an indicator of land degradation conditions using Remote Sensing and GIS in Guna-tana watershed. Trend studies and cross-sectional research design was employed, which produces data from the population at a particular point in time and to examine patterns of change with a mixed research approach to examine the degree of influence to measure the sensitivity analysis. A multi-criteria decision evaluation was used to create a vegetation vulnerability map for the research area. The vulnerability model was run using four sets of parameters: closeness to the road, slope, settlement closeness, and land use planning. Landsat imageries of 1995 and 2020 was used to conduct a comparative study of land use pattern. The study area has experienced a sequence of land degradation from 1995 to 2020, according to the results of multitemporal data. Agricultural and built-up lands have increased throughout this time, while forest and shrub land has decreased. The vegetation vulnerability of the area also shows that 19.23% extreme vulnerable and 67.03% very strongly vulnerable which is more than 80% of the area is highly vulnerable to vegetation. Vegetation suitability and land management evaluation is critical for determining the risk of land deterioration, that shows the adverse effects on ecological elements due to a decrease in metabolic capacity and patch disintegration processes.
