Abstract

Urban expansion occurs in big cities in Indonesia, including Batu City. An increase in the built-up area occurred in Batu City by 554.4 ha or 2.78%, and a decrease in agricultural land by 341.1 ha occurred in 2008-2018. If the Batu City government does not pay attention to the availability of environmental services or consider the geomorphological conditions of Batu City for developing settlements. In that case, it will have an environmental impact. The environmental problem in Batu City during the 2009-2019 period was an increase in greenhouse gases by 0.75% per year. Batu City is located in a hilly area. It is necessary to explore land capability in Batu City so that land use planning follows its environmental services and is sustainable. This study aimed to determine the land capability for settlements in Batu City based on the Regulation of the State Minister for the Environment Number 17 of 2009 concerning Guidelines for Determining Environmental Supporting Capacity in Regional Spatial Planning. This study used a geographic information system (GIS) and ArcGIS 10.8 software. The method used was overlapping soil texture, slope, drainage, effective soil depth, erosion, and flood potential maps. Batu City has a slope of 30-45% and a total area of 6,581.03 ha or 33% of the area of Batu City. The largest erosion rate reached 10,326.33 ha or 52% of the total area of Batu City. Erosion occurs on land used for agriculture or moorland. Soil protection and erosion control measures are strongly recommended. The area around Batu City, 1,174.28 ha, experienced considerable erosion, and 2,631.62 ha of land in Batu City is used for settlements. Land capability analysis can determine the starting point or basis for settlement land management in Batu City, which has a slope of more than 15%. There are only 461.9 ha of land management for settlement which follows the regional spatial planning and land capability in Batu City, spread over three different districts.

Abstract

In recent times, what is common in the scientific literature is findings showcasing the environmental and social menaces associated with artisanal and small-scale mining (ASM)–low-tech, low capital investment, and labor-intensive mineral extraction and processing. However, a better understanding of how ASM shapes livelihood and rural economies may present nuances as to how its negative ramifications can be addressed. As a result, this paper examines how galamsey engenders livelihoods and the transformation of rural economies in Ghana. We produced a nuanced counter-debate to the widely held view that galamsey is evil and a menace to national development by sourcing data from 236 operators using a questionnaire and key informant interviews with 11 relevant stakeholders in north-western Ghana. Findings show that galamsey is a source of employment, income, and accumulation of assets such as houses, motorbikes, cars, and filling stations, which together make the local economy thrive, thereby fostering a local economic boom. However, there is limited collaboration between regulatory agencies and local stakeholders in implementing sustainable mining policies in Ghana. To address this problem, the government should engage local community actors such as the chiefs and landlords, assembly members, and the lead miners on possible steps to streamline and effectively monitor galamsey operations as opposed to military clamp downs.

Abstract

The microbial fuel cell (MFC) is a device that harnesses microbial metabolism to convert chemical energy into bio-electrical energy. Extensive research has demonstrated its efficacy in both wastewater treatment and power generation applications. This study focused on the integration of a microbial fuel cell (MFC) with a biocathode constructed using the oxidoreductase-producing bacterium Bacillus sp. MCO22 and rice straw as a cost-effective substrate. The MFC utilized palm oil mill effluent (POME) as a chemical energy source for electricity generation in the anodic chamber. The ability of the MFC was evaluated by monitoring biochemical oxygen demand (BOD) activity and electrochemical properties. Post-operation, chemical oxygen demand (COD) and color removal were measured. The results revealed that the MFC with the BOD-based cathode achieved a maximum current density and power density of 0.58±0.01 A/m2 and 0.17±0.00 W/m2, respectively. Furthermore, it exhibited high COD and color removal rates of 95.10±0.10% and 98.53±0.33%, respectively, without requiring an external power supply. This study presents novel insights into utilizing a BOD-producing bacterium as a whole-cell biocatalyst on the MFC cathodic surface for both electricity generation and agricultural wastewater treatment.

Abstract

High-traffic highway crossing agricultural fields impacts the quality of food crops grown on Vertisol agricultural fields in Pasuruan. Lead (Pb) released from the exhaust of motor vehicles into the air can eventually enter the soil and be absorbed by plants. This study aimed to examine the effect of Pb from exhaust motor vehicles emission on the Pb status and its behavior in soil, water, and plants. The study was initiated by conducting a survey to determine the sampling locations in selected inundated paddy and maize cropping systems. A stratified random sampling method was used to collect soil, water, and plant samples. The soil of the study area is dominated by Vertisol, with clay content ranging from 54% to 76%. The soil attributes a high cation exchange capacity ranging from 80.53 meq 100 g-1 to 93.57 meq 100 g-1. Pb emitted from 2,913,000 vehicles within four months period that entered the agricultural field was not absorbed by paddy and maize crops. Pb entered the soil in the adsorbed form, and no Pb was observed in the soluble form, so it was not absorbed by the roots. In the paddy field, the total Pb of 84.33% was influenced by pollutant distance. Likewise, in the maize field, 83.18% of total Pb was influenced by pollutant distance. The far the pollutant distance from the agricultural field, the lower its total Pb. Paddy field water is adsorbed onto the colloidal clay, which is dispersed due to inundation and sloughing of the paddy, moving with the clay and then dissolved in the water flow.

Abstract

Cutleaf groundcherry (Physalis angulata L.) has the potential to be developed in various areas, including dryland. Information on drought-tolerant varieties, lines, or genotypes is needed for the development of cutleaf groundcherry in dryland. Selecting drought-tolerant lines is an alternative for alleviating yield loss potency caused by water shortages. A pot experiment that aimed to investigate the response of cutleaf groundcherry lines to a different level of water deficit, expressed in field capacity (FC), was run in two factors of factorial randomized block design. Each line (PA-01, PA-03, PA-05, PA-08) was set up in water deficit treatment (100, 80, 60, 40, and 20% FC). The result showed that vegetative growth and fruit production, such as fruit number and weight, mainly decreased at 60 or 40 % FC. In contrast, TSS increased at a higher water deficit which was in line with total flavonoid content, even inconsistently. PA-03 and PA-08 experienced a reduction in fruit weight at 40% FC, whereas other lines occurred at 60% FC. Water use efficiency (WUE) increased under severe water stress. Compared to other lines, PA-03 and PA-08 exhibit higher WUE at 60% FC. In conclusion, PA-03 and PA-08 lines were tolerant of water deficit.

Abstract

The effective management of natural resources is critical in achieving environmental sustainability, and it requires a careful balance of ecological and economic interests. Therefore, this study analyzed the effectiveness of village government policy in managing post-mining land for environmental sustainability using a non-doctrinal legal approach. Primary data were collected through interviews and observations, while secondary data came from regulations, scientific journals, and papers related to post-mining land rehabilitation governance. The study was conducted in Sukageuri View, Kuningan Regency. The study found that the policy implemented by the Cisantana Village Government in managing post-mining land through the establishment of the Village-Owned Enterprise (VOE) in 2016 has been effective. The area, formerly known as Sukageuri View, is home to various flora and fauna species, with several businesses operating and over 114,000 visitors engaging in social activities in 2022. Additionally, the site has contributed to the village's original income and supported the work program of the Cisantana Village Government. In conclusion, the policy implemented by the Cisantana Village Government effectively balances ecological, social, and economic factors, meeting the criteria for environmental sustainability.

Abstract

One method that can be used to improve soil properties is the addition of geopolymer cement to the soil to become more stable. This study aimed to determine the effect of geopolymer cement on soil stability. The raw materials for geopolymer cement include clay and basalt rock, with variations in the composition of 0%, 20%, 30%, 40%, and 50%. The levels of temperature variance used were 40 oC, 60 oC, and 80 oC, with variations in 4 and 6 hours. Characterization includes X-ray fluorescence (XRF), X-ray diffraction (XRD), and scanning electron microscope (SEM) tests of raw materials and products. The highest compressive strength was obtained on a mixture of 40% basalt, 200 mesh, and a heating temperature of 80 °C for 6 hours, 56.32 MPa. The California Bearing Ratio (CBR) test showed a significant increase in the heat treatment geopolymer products. The CBR value on y1 during the 10x collision was 16.67%; in the 30x crash, it increased to 63.33%, while in the 65x collision, it increased to 78.33%. Whereas in the Y2 measurement, at 10x collisions, it was 21.11%; at 30x collisions, the CBR value increased to 82.22%; and at 65x collisions, the CBR value increased to 100.00%.

Abstract

Volcanic eruptions are natural disasters with significant environmental and societal impacts. Timely detection and monitoring of volcanic eruptions are crucial for effective hazard assessment, mitigation strategies, and emergency response planning. Remote sensing technology has emerged as a valuable tool for detecting and assessing the effects of volcanic eruptions. One of the challenges in remote sensing image processing is handling large data dimensions that are difficult to address using traditional methods. Machine learning approaches offer a suitable solution to tackle these challenges. Machine learning demonstrates increasing computational capabilities, the ability to handle big data and automation. This study aimed to compare different machine learning classification algorithms, including Random Forest (RF), Support Vector Machine (SVM), Gaussian Mixture Model (GMM), and K-Nearest Neighbors (KNN). The data utilized in this study was derived from Sentinel-2A Multi-Spectral Instrument (MSI) imagery, which was tested in areas affected by the eruption of Mount Agung, Bali Province, in 2017. The results indicated that the GMM algorithm performed the best among the machine learning classifiers, achieving an Overall Accuracy (OA) value of 82.04%. It was followed by RF (78.86%) and KNN (77.55%). The areas affected by volcanic eruptions were determined by overlaying disaster-prone regions with areas mapped using the machine learning approach. The total affected area was measured as 29.89 km2, with an additional 3.31 km2 outside the designated zone. The findings of this study serve as a guideline for governmental entities, stakeholders, and communities to implement effective mitigation efforts for disaster risk reduction.

Abstract

Sand mining activities on agricultural land and rivers in Bambang Village, Wajak District, Malang Regency, have been ongoing for a long time. The sand mining activities on private agricultural lands, besides being illegal, also damage the land and the environment. In addition, these sand mining activities are also unsustainable. This study aimed to analyze and formulate sustainable alternative livelihoods of sand miners on agricultural lands in Bambang Village, Wajak District, Malang Regency, based on local resources. The study method was carried out using a combination of case studies and survey methods, accompanied by in-depth interviews and field observation. The in-depth interviews were conducted by interviewing 60 respondents for key informants from miners, farmers, many stakeholders, and experts that were selected purposively. The data obtained were analyzed using a multi-criteria analysis (MCA), namely PROMETHEE (Preference Ranking Organization Methods for Enrichment Evaluation) program to formulate sustainable alternative livelihoods. The results showed that the best alternative sustainable livelihood at this location is agriculture. The second best alternative sustainable livelihood is ecotourism, the third is animal husbandry, and the fourth is informal sectors based on local resources. The government should support the development of agriculture, ecotourism, animal husbandry, and the informal sectors in the village.

Abstract

The study, which aimed to analyze the use of chemical fertilizers and pesticides using the Cobb-Douglas production function approach and their reallocation to increase the income of vegetable farmers and prevent land degradation, was conducted in Sumberejo Village, Batu City, Indonesia. Data were collected from 138 pakcoy (Brassica rapa), celery (Apium graveolens), and red chili (Capsicum annuum) farmers through interviews using a questionnaire. The relationship between input and output was analyzed by regression with the Cobb-Douglas production function. Data validity, reliability, and classical assumption tests were performed to ensure the goodness of fit regression model. Furthermore, the F test and t-test were applied to analyze production response to chemical fertilizers and pesticides. This study revealed that the modeled regression equation is appropriate, where R2 = 0.827-0.933. Vegetable production gives a different response to the use of chemical fertilizers (TSP, Urea, and NPK) and pesticides. Increasing this chemical in pakcoy and celery farming is possible, but it needs to be considered because it has no significant effect on increasing production. The productivity of these two types of plants is relatively high. Farmers need to compare the costs of adding these inputs to additional income and the possibility of land degradation. Chemical fertilizers and pesticides have been excessive in red chili farming, so productivity is very low. There are indications that the land has been degraded, but to be sure, a study is needed on the chemical content of the vegetable fields in Sumberejo Village and the optimal use of chemical fertilizers and pesticides.
