Purpose: This study examines the impact of rubber price fluctuations on the income and welfare of rubber farmers in Lubuk Rengas Village, Rantau Bayur Subdistrict, Banyuasin Regency, and identifies strategies to increase income amid market uncertainties. Methodology/approach: Using a mixed methods approach, qualitative and quantitative data were collected from 35 farmers through questionnaires. Spearman correlation was applied to assess the relationship between price fluctuations and income, while SWOT analysis identified strategic options. Results/findings: The results show a strong, significant correlation between price fluctuations and farmers’ income (r = 0.831, p < 0.001). Key strategies include adopting pest-resistant clones, rejuvenating old plants, diversifying with intercropping and livestock, and enhancing farmer skills. Institutional support—through better financing access and private sector partnerships—is essential, while SWOT analysis highlights the need to maximize strengths and opportunities and mitigate weaknesses and threats like price volatility and climate change. Conclutions: Price fluctuations significantly affect farmers’ income, requiring sustainable, integrated strategies supported by institutional collaboration to safeguard and improve welfare. Limitations: The small sample size and single-location focus may limit generalizability; the cross-sectional design does not capture long-term trends. Contribution: This study provides empirical evidence on the link between commodity price volatility and farmers’ income, offering practical strategies and policy recommendations for resilience in volatile markets

Purpose: The purpose of this study was to determine the legal arrangements for the place of entry and release of animal and plant quarantine carrier media, and the factors, constraints, solutions, and implementation of the place of entry and release of animal and plant quarantine carrier media. Methodology: The research method of this thesis is normative juridical (legal research) through a literature study with an empirical juridical approach (sociological juridical) through field studies aimed at empirically obtaining legal knowledge. Results: Quarantine entry and exit regulations are based on Articles 86 and 87 of Law No. 21 of 2019. The Batam Quarantine Center shows strong biosecurity efforts despite challenges in resources and coordination. Solutions include technology use, staff training, and improved collaboration. Conclusions: The enforcement of quarantine entry and exit points in Batam reflects Indonesia’s strong commitment to biological security. Despite logistical and human resource challenges, legal compliance is improved through regulatory reforms, stakeholder collaboration, and continuous system evaluations. These measures collectively strengthen the country’s quarantine system and environmental protection. Limitation: This study is geographically limited to Batam City and relies primarily on qualitative analysis, which may not reflect broader implementation challenges across other regions in Indonesia. Contribution: This study contributes to the development of quarantine law enforcement strategies and provides practical insights for policymakers and quarantine agencies to strengthen institutional coordination, improve resource allocation, and enhance the effectiveness of biosecurity at entry-exit points.
