Abstract

Heavy metals are the main pollutant substances in the environment. Heavy metals are a type of metal with high density and are very dangerous to living organisms, especially humans. Living organisms can adsorb the bioaccumulative and sedimentation of heavy metals that settle in water. Some compounds which found in wastewater including Cadmium (Cd), Copper (Cu), Iron (Fe), and Lead (Pb). These heavy metals cannot naturally degrade, additional processing is required before it being released into the environment. To prevent environmental pollution impacts, wastewater containing heavy metals must be handled properly and optimally. One method that can be applied for wastewater treatment is degradation by photocatalysis, utilizing the assistance of light. This research is to investigate the effect of pH and irradiation time on the degradation of Cd (cadmium), Cu (Copper), Fe (Iron), and Pb (Lead) heavy metals. To enhance the photocatalytic activity, the synthesis of ZnO-Zeolite nanocomposites was conducted. The ZnO-Zeolite nanocomposites produced were analyzed by SEM-EDX and XRD. The utilization of ZnO-Zeolite nanocomposites is deemed effective in reducing heavy metal concentrations. The degradation with Ultraviolet (UV) light exposure runs within 15-120 minutes with pH variation between 4-8. The degradation of heavy metal runs at 60 minutes and 120 minutes showing an optimum percentage removal of metals approaching 100%. The optimum pH values for Cd, Cu, Fe, and Pb are pH 8, pH 7, pH 6, and pH 8, respectively. The sequential metal degradation percentages are 98.96%, 95.43%, 96.07%, and 95.53%, respectively.

Abstract

This study used a novel method to transform rice husk waste into a highly effective and specific adsorbent for several dyes, including malachite green, direct yellow, congo red, and rodhamine B. The rice husk was analyzed and used for the purpose of eliminating these colors from water-based solutions. The adsorbent exhibited excellent heat stability, and the sample retained the functional groups of lignin. The parameters pertaining to kinetics were also examined. The adsorption exhibited a time-dependent rise and reached its peak after 100 minutes. In the kinetics tests, the most suitable model to characterize the behavior was found to be the pseudo-first order, with a regression value near to one. The rice husk shown significant potential and selectivity in the removal of malachite green and rodhamine B, particularly in the presence of direct yellow and congo red, from aqueous solutions.

Abstract

Many surface waters in the world are impounded by eutrophication due to the global warming phenomenon. This study analyzed the trophic level in the Bangka Strait, a busy pathway that connects two provinces (Bangka and South Sumatra) of Indonesia, using MODIS-Terra chlorophyll-a (Chl-a) data from the 2020 year. We applied the GIS analysis to generate Chl-a concentration and trophic state maps over the study area. The results of the study revealed that the mesotrophic, eutrophic, and oligotrophic status encompass 50%, 43%, and 7% of the Bangka Strait region, respectively. The highest concentration of Chl-a was observed in May (5.38 g/L), while the lowest was observed in September (3.02 g/L). Our study revealed that the high Chl-a concentration was primarily due to nutrient contributions from South Sumatra rivers. On the other hand, the COVID-19 restriction policy significantly reduced Chl-a from July to October. The trophic state of the Bangka Strait was at a mesotrophic level, and the major contributors to the trophic condition in the strait came from the coasts of South Sumatra, which mostly consisted of agricultural and aquacultural activities. These findings will be useful in developing an effective policy for monitoring and protecting surface waters from eutrophication events.

Abstract

The cajuput plant (Melaleuca cajuputi) is valued for its essential oil production and its ability to thrive in challenging environments, including post-mining lands. PT Bukit Asam Tbk (PTBA) has cultivated this plant extensively to supply seeds for reclamation projects on former mine sites, along with the provision of location-specific fertilizers. This study aims to identify the new alternative organic materials, determining the optimal formula for plant growth media and also to measure the tangible and intangible impacts of the community involvement. Following the implementation of statistical testing involving the analysis of variance model (ANOVA) and subsequent test, which is the least significant difference (LSD) test, definitive findings reveal that incorporating coffee exocarp as a growth medium significantly impacts the elevation of plant height and the augmentation of Cajuput leaf count. The most efficacious treatment is delineated as P2, characterized by a 1:1 composition of coffee exocarp and soil. The involvement of the local community has precipitated several advantageous outcomes, encompassing the creation of employment opportunities, the facilitation of economic equilibrium, and the development of smallholder forestry enterprises within the local community.

Abstract

The world’s attention to climate issues is increasing as the issue of global warming and climate change emerges. Several studies with the scope of cities and urban areas concluded that urban surface temperatures have an increasing trend. This phenomenon will have an impact on the thermal comfort of urban population. Yogyakarta City as one of the National Activity Centers (PKN), is experiencing rapid urban development and leads to become a metropolitan city so it needs to be studied regarding its thermal comfort. This research is intended to identify the potential and vulnerability of thermal discomfort in Yogyakarta City. The identification of potential discomfort is carried out using the Discomfort Index (DI) approach and the Land Surface Temperature (LST) value. Meanwhile, vulnerability is identified in the social aspects of population. Furthermore, the potential and vulnerability scores are assessed to get an overview of thermal discomfort mitigation priorities. Based on DI analysis, thermal discomfort is felt by more than 50% of the Yogyakarta’s residents and it is estimated that in the future will get worse. By looking at the distribution of LST values, the high potential for discomfort is in the city center and has expanded to the north and northeast. Meanwhile, areas with high vulnerability are located in the center and south side of Yogyakarta City. From the combined assessment of threat and vulnerability, the areas that are the top priority for mitigation are in the center of Yogyakarta City, which include 7 districts, namely Danurejan, Gedongtengen, Gondomanan, Jetis, Kraton, Ngampilan, and Pakualaman. The medium priority districts are Gondokusuman and Wirobrajan.

Abstract

Extreme rainfall impacts rubber production, reducing effective tapping days and cumulative annual output and having a wide-ranging effect on rubber crop cultivation. This study aimed to find out how rainfall and rainy days affected the rubber production of the Kusen clone in Muara Enim Regency’s Rambang District. The study was conducted on a rubber plantation of Kusen clone, which has an area of 1 ha. The initial stage in analyzing the impact of climate change on Kusen clone rubber production in Rambang District, Muara Enim Regency, was identifying the independent and dependent variables. The T-test was conducted to see whether each independent variable partially has a significant effect on the dependent variable. Rubber production has fallen year after year, with an average of 205.12 kg/ha in 2019 during the first year of tapping and 118.43 in 2023. The coefficient value (r) shows a 27.2% (sufficient correlation) magnitude association between the rainfall and rainy-day variables and the rubber productivity variable of the Kusen clone. In Correlation test results, rainfall and rainy days are strongly associated with producing Kusen clone rubber, as demonstrated by the correlation analysis value of 0.846. Regression research showed that rainfall and rainy days had a statistically insignificant effect on rubber production on the rubber clone Kusen in Rambang District, Muara Enim Regency.

Abstract

Mining is an important global economic driver, contributing to human civilization’s advancement and foreign exchange revenues. However, it causes significant environmental contamination, particularly in developing nations with inadequate waste management and ineffective mining legislation. In the present study, the source distribution and ecological risk of heavy metals (HMs) from the soils of the mining area around Riruwai town, northern Nigeria, were assessed. Soil samples were obtained from active and abandoned mining sites, farmlands, and control sites and were analyzed for physicochemical characteristics and HM contents. The measured concentrations of HMs were used to evaluate the source distribution and ecological risks. The study’s findings indicated that, with the exception of Mn, Hg, and Ni, all HM concentrations were above threshold levels in all sample locations aside from the control sites. The results of the correlation analysis showed that there was a significant correlation between the HMs, indicating that they came from comparable origins. Principal component analysis and hierarchical cluster analysis results indicated that As, Cr, Hg, Ni, and Zn might originate from similar anthropogenic sources, possibly mining activities, while Cd, Mn, and Pb might come from natural sources (parent material). Results of an ecological risk assessment revealed that the soils from active and abandoned mining sites were severely polluted by HMs. The degree of pollution has begun to extend onto farmland, signifying a critical need for adequate HM pollution control in the study area.

Abstract

Carbonaceous substances, including hydrochar and biochar, have been produced from agricultural residue via hydrothermal and pyrolysis processes. The surface morphology of the materials was assessed using FTIR, XRD, BET, and SEM techniques. The identification of diffraction peaks at approximately 22° by XRD analysis suggested the existence of carbonaceous material. This is confirmed by FTIR analysis, which identifies cellulose vibration at 2931 cm?1. The results of the SEM analysis revealed that BC-Rice husk and HYC-Rice husk are heterogeneous in shape and surface area; conversely, HYC-Rambutan and Duku have a uniform, ball-like shape and aggregate. This is further corroborated by surface area data, which indicates that the material composed of rice husk has a larger surface area than the material composed of fruit peel.
