Abstract

Illegal gold mining (PETI) in Sijunjung Regency has triggered a severe environmental crisis, characterized by widespread heavy metal pollution from mercury (Hg) and arsenic (As) that threatens ecosystems and public health. To comprehensively assess this issue and evaluate existing management policies, this study conducted a systematic review following the PRISMA 2020 guidelines, synthesizing evidence from 20 empirical studies. The results reveal that heavy metal concentrations in water, sediment, soil, and biota significantly exceed quality standards, with a clear spatial gradient emanating from PETI sites and a worrying increasing trend over time. Concurrently, the evaluation of management policies uncovered critical weaknesses, including institutional fragmentation, low law enforcement effectiveness (achieving only 45% of its target), and an over-reliance on ineffective repressive measures. In conclusion, the findings underscore the urgent need for a fundamental policy shift from a repressive to an integrative and sustainable model. This study proposes an evidence-based framework that combines stringent regulation, real-time monitoring, community-based economic empowerment, and public health interventions to holistically address the root causes and multifaceted impacts of PETI in Sijunjung.

Abstract

The global water pollution crisis exacerbated by anthropogenic activities demands effective integration between science and policy. This study conducted a comprehensive bibliometric analysis of 285 publications to map the intellectual landscape and evolutionary trajectory at the interface of liquid waste contamination and environmental policy. Findings reveal an exponential acceleration of research since 2014, with 75.78% of publications concentrated in the last decade, reflecting increasing global urgency. China dominates as the research epicenter with the highest productivity (56 publications), the greatest citation impact (1,914 citations), and a role as a key collaboration link. Thematic analysis confirms the consolidation of this field around the core concepts of “environmental policy” (228 occurrences) and “wastewater treatment” (215 occurrences), marking a paradigm shift from technocratic approaches toward holistic policy integration. However, the polarization of international collaboration into 10 cohesive clusters indicates a fragmentation of global discourse. Critically, this study identifies an alarming disparity between rapid scientific progress and lagging policy adoption capacity, highlighting the urgent need for adaptive policy frameworks and transdisciplinary collaboration mechanisms to bridge the implementation gap and respond more effectively to emerging contaminants.

Abstract

Agrotourism is a series of tourism activities that utilize agricultural potential as tourist attractions that can be enjoyed through natural scenery, plant and animal conservation, educational activities in agricultural and plantation areas that have a diversity of production activities and technologies, and can also promote community culture. Agrotourism potential can be developed through integrated agriculture such as farming, animal husbandry, and educational tourism. This study aims to identify the development of research related to the sustainability of agrotourism conducted worldwide through data obtained from relevant journals for the period 2000 to 2025. There are 58 studies related to the sustainability of agrotourism. The method used in this study is the Systematic Literature Review (SLR) method. The SLR method is used to identify, review, evaluate, and interpret all available research in fields and topics related to relevant and specific research questions. Using the SLR method, systematic reviews and journal identification can be carried out, with each process following predetermined steps or protocols. The results of this study show that agrotourism research has shown consistent growth from 2000 to 2025, with a significant surge in 2024, indicating the importance of agrotourism in sustainable tourism. The country conducting the most research in the field of agrotourism sustainability is Indonesia, with research based on the number of citations each year 2000 to 2025 being 4 out of 20 studies.

Abstract

The Harau Valley Nature Tourism Park (TWA) faces complex sustainability challenges, with an increase in tourist visits reaching 270,790 visitors in 2022. This has led to ecological pressure, multi-stakeholder conflicts, and ambiguity regarding the destination's identity between conservation and commercial functions. This Systematic Literature Review (SLR) analyzes the multidimensional sustainability status (ecological, socio-cultural, economic, infrastructure), identifies gaps between formal public policy frameworks and field implementation practices, and formulates evidence-based, integrative policy recommendations. The study analyzes five peer-reviewed articles (2017-2024) using a multidimensional framework with MDS (Multidimensional Scaling), TALC (Tourist Area Life Cycle), and GRADE evidence synthesis. Inclusion criteria: publications in Indonesian/English, quantitative/qualitative/mixed-methods methodologies, field-based empirical research. The multidimensional sustainability index reached 59.45 (moderately sustainable) with dimension heterogeneity: ecology 66.52, infrastructure 65.66, economy 54.14, socio-culture 51.48. The optimal carrying capacity is 315,169 people/year, but temporal distribution is uneven, creating seasonal pressure. A significant gap was identified between formal regulations (Ministerial Decree, Regional Regulation) and implementation practices. The local leadership model of Tungku Tigo Sajarangan offers potential conflict resolution mechanisms for stakeholders. The Harau Valley Nature Tourism Park requires an integrative policy framework that balances conservation objectives, local livelihoods, and visitor satisfaction through community-centered governance, evidence-based quota systems, and the revitalization of traditional local leadership. A phased implementation is recommended, focusing on critical infrastructure (0-1 year), governance restructuring (1-3 years), and long-term ecological conservation (3-5 years).
