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

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.

Abstract

The Environmental Impact Analysis course is one of the compulsory subjects in the Environmental Engineering Study Program, Jambi University. This course studies sustainable development, environmental issues, use of AMDAL, screening and scoping process, AMDAL methodology, UKL-UPL, DELH, DPLH, environmental audit and KLHS. One of the efforts to obtain optimal course learning outcomes, an active learning model is needed that can provide opportunities for students to design assignments and explore information to be applied. A learning model that can provide experience, knowledge, skills and attitudes for students, namely the project-based learning (PBL) model. The purpose of this study is to see the effectiveness of this project-based learning model in optimizing learning outcomes for the Environmental Impact Analysis course. This research was carried out in the Odd Semester of the 2022/2023 Academic Year. Based on the research results, it is known that this project- based learning model can improve learning outcomes for the Environmental Impact Analysis course. This can be seen from the results of the evaluation of the Environmental Impact Analysis course in the Odd Semester of the 2021/2022 Academic Year, namely the average quiz score of 60.65 and an increase in the Odd Semester of the 2022/2023 Academic Year, namely the average quiz score of 81.75. The results of the measurement using a questionnaire showed that as many as 83% of students considered the project-based learning model to improve understanding in the Environmental Impact Analysis course.

Abstract

This mentorship and workshop aimed to enhance the capacity of environmental activists to understand and apply statistical analysis to environmental issues. Through the use of Vizly (AI-Powered Data Analysis), participants were introduced to an artificial intelligence-based approach that simplifies data processing, visualization, and interpretation of results. The workshop method included intensive mentoring, theoretical presentations, and hands-on practice using relevant environmental data, such as air quality, waste management, and renewable energy utilization. The workshop was conducted in a systematic manner: identifying participant needs, introducing basic statistical analysis concepts, simulating the use of Vizly, and post-workshop mentoring to ensure continued understanding. The results demonstrated improved skills among participants in processing environmental data more quickly, accurately, and evidence-based. Vizly has been proven to assist environmental activists in producing analyses that can support decision-making, policy advocacy, and environmental program planning. The implications of this activity include facilitating the integration of AI technology into environmental work, while also opening up opportunities for collaboration between academics, government, and communities.

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 water quality of rivers can deteriorate due to the large amount of pollutants entering the river. Water quality assessments provide an overview of the actual state of water quality. The WQI can provide valuable information about the water quality of rivers. The calculation of the water quality index is carried out because there is a high probability that other parameters also exceed the quality standards, which are not considered when calculating the water quality index. Therefore, it is very important to assess the water quality of the river. The objective of this study was to assess the water quality of the Asam River, Jambi City. The research methodology involved collecting water samples from the Asam River at locations I (upstream), II (middle) and III (downstream) and testing the samples in the laboratory. Indices were analyzed using WQI for the following variables: temperature, total suspended solids (TSS), pH, BOD, COD, nitrate, total phosphate, dissolved oxygen and fecal coliforms. The method using WQI to determine water quality classification values ​​can serve as a reference for problem solving and evaluation of water pollution management. The results based on the calculations resulted in a WQI value of 96,27 at location II (middle); 70,95 at location I (upstream) and 186,01 at location III (downstream). The results of the study on the water quality of the Asam River are as follows: 1) very low water quality, 2) low quality water and 3) unfit for drinking water, posing a risk to aquatic life and human health.
