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

The soil polluted by heavy metals in the old Talang Gulo TPA has been a waste disposal site for many years, so that the surrounding soil is contaminated with the heavy metals mercury, chromium and arsenic. For this reason, it is necessary to know the concentrations of heavy metals Hg, Cr, As, and to test the effectiveness of vetiver (Vetiveria zizanioides) in reducing the content of Hg, Cr, and As metals in polluted soil in the old TPA Talang Gulo Jambi TPA. The research method was in the form of a preliminary survey with the type of research being carried out in an experimental manner, to restore heavy metal polluted soil using the phytoremediation method using vetiver (Vetiveria zizanioides). The results showed that the height and weight growth of Vetiveria zizanioides based on the results of ANOVA statistical calculations showed that Vertiveria zizanioides plants did not differ significantly in plant growth between polluted soil and control soil. As well as the effectiveness of vetiver (Vetiveria zizanioides) in reducing the metal content of Hg, Cr, As, in TPA Talang Gulo Jambi. Shows a decrease in metal content that occurred for 8 weeks. The absorption of metal mercury (Hg) is T1 0.606 mg/kg (56%), T2 0.599 mg/kg (57%), T3 0.544 mg/kg (60%), T4 0.324 mg/kg (76%) on chromium metal (Cr) of T1 1.348 mg/kg (39%), T2 1.248 mg/kg (44%) , T3 1.078 mg/kg (51%), T4 0.759 mg/kg (76%), and in arsenic metal (As ) T1 0.904 mg/kg (46%), T2 0.759 mg/kg (55%), T3 0.685 mg/kg (59%), T4 0.589 mg/kg (65%).

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.
