Abstract

Former solid waste disposal at Talang Gulo TPA Jambi City implements a waste management system using a controlled landfill. Leachate and rainwater absorb into the soil and accumulate to become polluted groundwater. Furthermore, the polluted water flows into the dug well water and can reduce the quality of the dug well water. The aim of this study is to determine the heavy metal pollution index of residents' dug well water and the influence of the distance between the ex-TPA and dug well water. This research method is purposive sampling based on the distance of heavy metal sample points, namely 70 m, 230 m and 300 m. Sample analysis used an Atomic Absorption Spectrophometer (AAS) in the laboratory. The results were classed and indexed (C/P), the groundwater was very lightly contaminated with Cd (<0.1), heavily contaminated with Fe (0.51-0.75), very lightly contaminated with Cr (<0.1), and moderately contaminated with Cu (0.26-0.50). Based on the R value of the four metals, it shows that there was a very high influence between the distance between the well water sample and the former solid waste disposal leachate product.

Abstract

Industrial and operational activities in various sectors, such as manufacturing, oil, gas, mining, and healthcare, have the potential to generate hazardous and toxic waste (B3) that can contaminate the environment, endanger human health, and threaten occupational safety. The management of B3 waste, which includes collection, storage, transportation, and final processing, carries a high risk of accidents and exposure to hazardous materials. These risks are generally due to workers' lack of knowledge of safe work procedures, improper use of personal protective equipment (PPE), and the failure to implement optimal occupational safety standards. The purpose of this study was to analyze the effectiveness of Safe Work Practices (SWPs) using the Hazard Identification, Risk Assessment, and Risk Control (HIRAC) approach at each stage of B3 waste management, from generation, packaging, and storage to transportation. The methods used included field observation, data collection from company documents, and risk analysis based on probability and severity matrices. The study results indicate that the implementation of SWPs has been generally effective, characterized by a predominantly low to moderate risk level. Therefore, the implementation of SWPs plays an important role in minimizing potential hazards in B3 waste management, but it is necessary to strengthen operational discipline and optimize supporting facilities to improve occupational safety performance.

Abstract

Tourism activities are a necessity for individuals and communities because they provide a refreshing impact, both physically and spiritually. One tourism activity that can bring humans closer to nature and the Creator is ecotourism or ecological tourism. This study aims to analyze the factors influencing public perceptions and preferences in Jambi Province towards Ecological Tourism during the Covid-19 Pandemic, spanning the initial pandemic period, PSBB, PPKM, New Normal, and post-pandemic. This research method uses a quantitative approach with primary data from a survey in the form of questionnaires distributed to the community, which data analysis uses SEM-PLS assisted by Smart-PLS software. The results of this study suggest that based on the SEM-PLS path diagram, the path coefficients indicate that all aspects of visitor assessments of ecological tourism destinations in Jambi Province need to be improved, especially related to tourist destination cleanliness, ecological tourism accessibility, tourist attractions, and infrastructure conditions. Therefore, good cooperation between the community and the government is highly recommended in the management of ecological tourism areas in Jambi Province.

Abstract

This study examined the potential of water jasmine (Echinodorus palaefolius) in reducing manganese levels in Coal Acid Mine Drainage (AMD) using an artificial wetland system. The study was conducted experimentally with time variations of 0, 3, 6, and 9 days, where the manganese concentration was analyzed using Atomic Absorption Spectrophotometry (AAS). The results showed that the initial manganese concentration of 9.75 mg/L, which exceeded the quality standard of the Minister of Environment Decree No. 113 of 2003 (4 mg/L), decreased significantly to 3.94 mg/L on the 3rd day and reached 1.002 mg/L on the 9th day with an effectiveness of 89.73%. An independent t-test showed a significant difference (p < 0.05) between with and without plants. The BCF value of 7.028 classifies E. palaefolius as a highly effective accumulator, while the TF value of 0.6 indicates the presence of a phytostabilization mechanism. Research has proven that water jasmine is effective as an environmentally friendly solution for coal-fired wastewater management with the ability to neutralize pH from 4.28 to 6.53 and reduce manganese concentrations below quality standards in a short time.

Abstract

The global transition toward renewable energy is increasingly urgent to mitigate climate change and reduce dependence on fossil fuels; however, it also introduces economic risks such as greenflation, driven by rising demand for green commodities. In Indonesia, renewable energy development has become a national priority, with Jambi Province identified as a strategic region due to its significant micro-hydropower (PLTMH) potential. This study aims to predict PLTMH potential as a means of supporting energy transition planning and preventing greenflation through data-driven policy decisions. The research employs a Bayesian Structural Time Series (BSTS) approach using JASP software, integrating Kalman Filter, spike-and-slab regression, and Bayesian Model Averaging. Time series data from 2008–2024 were analyzed with 2,000 MCMC draws and a 1% burn-in to ensure estimation stability. The results demonstrate a strong upward trend in PLTMH capacity, with high model accuracy indicated by an R² value of 0.991, low residual standard deviation, and acceptable prediction uncertainty. Forecasts suggest continued growth in PLTMH capacity over the next two decades before reaching a steady state. The study concludes that BSTS is a robust and reliable method for predicting renewable energy potential and supporting counterfactual policy analysis. This research contributes empirically to applied Bayesian time series modeling and practically to renewable energy policy planning, offering evidence-based insights to enhance energy security and mitigate greenflation risks.
