Estimation of Potential Soil Erosion and Sediment Yield: A Case Study of the Transboundary Chenab River Catchment
No full textNear real-time estimation of soil loss from river catchments is crucial for minimizing environmental degradation of complex river basins. The Chenab river is one of the most complex river basins of the world and is facing severe soil loss due to extreme hydrometeorological conditions, unpredictable hydrologic response, and complex orography. Resultantly, huge soil erosion and sediment yield (SY) not only cause irreversible environmental degradation in the Chenab river catchment but also deteriorate the downstream water resources. In this study, potential soil erosion (PSE) is estimated from the transboundary Chenab river catchment using the Revised Universal Soil Loss Equation (RUSLE), coupled with remote sensing (RS) and geographic information system (GIS). Land Use of the European Space Agency (ESA), Climate Hazards Group InfraRed Precipitation with Station (CHIRPS) data, and world soil map of Food and Agriculture Organization (FAO)/The United Nations Educational, Scientific and Cultural Organization were incorporated into the study. The SY was estimated on monthly, quarterly, seasonal, and annual time-scales using sediment delivery ratio (SDR) estimated through the area, slope, and curve number (CN)-based approaches. The 30-year average PSE from the Chenab river catchment was estimated as 177.8, 61.5, 310.3, 39.5, 26.9, 47.1, and 99.1 tons/ha for annual, rabi, kharif, fall, winter, spring, and summer time scales, respectively. The 30-year average annual SY from the Chenab river catchment was estimated as 4.086, 6.163, and 7.502 million tons based on area, slope, and CN approaches. The time series trends analysis of SY indicated an increase of 0.0895, 0.1387, and 0.1698 million tons per year for area, slope, and CN-based approaches, respectively. It is recommended that the areas, except for slight erosion intensity, should be focused on framing strategies for control and mitigation of soil erosion in the Chenab river catchment.Water Resource

Effect of Knowledge toward the Behaviour of Gold Miners Environmentally Sound: A Case Study in Bombana Regency
No full textAbstrak
Gold is a mineral pursued by miners around the world. Wherever there is potential sounding gold by miners, then they instantly met by traditional gold miners either from outside, inside or around the mine area. With the discovery
of gold deposits in Bombay, it invites much traditional gold miners to do mining there. The more traditional miners, then affect on environmental damage are more quickly. In order to minimize damage from traditional
miners, it required an examination ofthe miners, particularly how the level of environmental knowledge miners toward the behaviour of environmental management at the mine location. The results showed that although the level of education ofthe miners is low, but their experience and behaviour towards environmental management are quite high. It is caused by the presence of other factors that they have such as experience, media or info, mature age, social, and culture

Namun bagi masyarakat Islam, pemanfaatan fintech tidak hanya ditinjau dari aspek manfaat dan resikonya, melainkan harus didasarkan pada penegakan prinsip-prinsip muamalah Islam untuk memastikan kepatuhan terhadap ajaran agama yang bermuara pada kemaslahatan dan kesejahteraan masyarakat. Adapun tujuan penelitian ini, yakni untuk menganalisis peran Financial Technology (Fintech) dalam pemberdayaan ekonomi umat melalui perspektif Hukum Ekonomi Syariah dengan menggunakan pendekatan kualitatif deskriptif-analitis. Hasil penelitian menunjukkan bahwa fintech dengan pengawasan pemerintah yang ketat dapat menjadi alat yang efektif dalam memberdayakan ekonomi umat, mendukung kesejahteraan sosial, dan memajukan inklusivitas keuangan sesuai dengan prinsip-prinsip Islam yang berorientasi pada kemaslahatan
Model-Based Design, HIL Testing, and Rapid Control Prototyping of a Low-Cost POC Quadcopter with Stability Analysis and Control
No full textUnmanned aerial vehicles (UAVs), particularly quadcopters, have several medical, agriculture, surveillance, and security applications. However, the use of this innovative technology for civilian applications is still very limited in low-income countries due to the high cost, whereas low-cost controllers available in the market are often tuned using the hit and trial approach and are limited for specific applications. This paper addresses this issue and presents a novel proof of concept (POC) low-cost quadcopter UAV design approach using a systematic Model-Based Design (MBD) method for mathematical modeling, simulation, real-time testing, and prototyping. The quadcopter dynamic model is developed, and controllers are designed using Proportional Integral, and Derivative (PID), Pole Placement, and Linear Quadratic Regulator (LQR) control strategies. The stability of the controllers is also checked using Lyapunov stability analysis. For verification and validation (V&V) of the design, Software-in-the-Loop, Processor-in-the-Loop, Hardware-in-the-loop testing, and Rapid Control Prototyping have been performed. The V&V methods of the MBD approach showed practically valid results with a stable flight of the quadcopter prototype. The proposed low-cost POC quadcopter design approach can be easily modified to have enhanced features, and quadcopters with different design parameters can be assembled using this approach for a diverse range of applications
Identification of potential mineral in a mining area plan using geoelectrical investigation
No full textThis geological structure estimation is done by flowing an electric current under the surface, then analyzing the different electrical resistance depending on the rock's quality, the degree of density, and soil moisture conditions. The research location is in East Kabaena, Bombana Regency, Southeast Sulawesi Province. The type of tool used is the G-Sound, a cheap and reliable resistivity (geoelectric) measurement tool. The geoelectric method used in this exploration is the resistivity method with the Schlumberger Method electrode configuration. Then the interpretation of the geoelectric survey data using the IP2Win software represents a sounding point. The results of field investigations found that the limonite layer with groundwater content had a resistivity value range of 0.28 -20.00 ohm-m. Then the limonite layer with a few chunks of rock with a resistivity value of 50.00 - 150 ohm-meters. The saprolite layer contains groundwater with a resistivity value of 100-200 ohm-m. The bedrock layer with a resistivity value greater than 5.034.00 - 23.351.00 ohm-m is the lowest part of the laterite profile. The nickel laterite is in the limonite and laterite layers with a resistivity value of 50.00 - 150 ohm-m with an estimated layer depth between 3 - 50 meters. The thickness of the layer ranges from 8 - 15 meters. Boring tests must accompany the use of geoelectric tools for the identification of soil structures. Interpretation of geoelectric data on metallic mineral resources includes the interpretation of geoelectric data into geological conditions
Cascading Failures Assessment in Renewable Integrated Power Grids Under Multiple Faults Contingencies
No full textCascading overload failures occurred in power systems due to higher penetration of renewable energy resources (RERs), which causes uncertainty in a grid. To overcome these cascading overload failures, proper assessment in the form of load flow balancing and transients stability is required in renewable integrated power grids (RIPGs). This problem becomes more critical in the occurrence of multiple intervals faults in multiple interconnected RIPGs, which causes the tripping of several RERs. Due to which outages occurred in various transmission lines, which lead the power system to cascading overload failures. To tackle this problem, hybrid probabilistic modeling is proposed in this paper for balancing load flow and an assessment of transients stability in multiple interconnected RIPGs. For balancing of load flow, a smart node transmission network topology is utilized along with integrating a unified power flow controller (UPFC), while transients instabilities are assessed through a UPFC alone. Contrary to the previously proposed algorithms, which are only suitable to compensate network instabilities in case of only a single interval fault, this work is supported by probabilistic modeling to compensate network instabilities under the occurrence of not only a single interval fault but also in case of more severe multiple intervals faults in multiple interconnected RIPGs that will lead the network to cascading failure outages. Simulation results verify that our proposed probabilistic algorithm achieved near an optimal performance by outperforming the existing proposed methodologies, which are only confined to mitigate the effect of network instabilities only in case of single interval fault and fails to address these network instabilities under the occurrence of severe multiple interval faults, which leads the network to cascading failure outages. These simulation results are also validated through an industrial case study performed on a western Denmark transmission network to show the superiority of our proposed algorithm
Detection of Changes in Surface Water Bodies Urban Area with NDWI and MNDWI Methods
No full textLand surface water bodies, an essential part of the Earth's water cycle such as rivers, lakes, swamp, and reservoirs, influence the global ecosystem and climate global significantly. Makassar, one of the most populated cities in Indonesia, recently experiences massive development that affects the existence of vegetation area and urban aquatic ecosystem. This study attempts to detect the urban surface water bodies and to monitor the change by using Landsat OLI TIRS. In order to extract the high accuracy of data, the image data utilized in this study was acquired by Landsat 8 OLI TIRS sensor on 14 December 2000, 27 December 2009 and 06 January 2019 from the United States Geological Survey (USGS) portal analyzed by Normalized Difference Water Index (NDWI) and Modified Normalized Difference Water Index (MNDWI). These methods are scientifically used to classify the data into two categories consisted of water and non-water objects. The result shows that in the last nine years, urban surface water bodies increased around 129.8 ha distributed mostly in Manggala area. Due to rapid urban development such as housing, makes the urban runoff concentrating in low land and creates giant swamp as well as an urban wetland. In coastal areas however decline of the water body due to dominantly by massive reclamation, housing and factory settlement. The increase of urban surface water bodies can lower the urban heat while massive development in the built-up area can worsen the urban heat
