To ensure food availability across Indonesia and mitigate potential food crises, the government introduced the Food Estate program under Presidential Regulation No. 109 of 2020. This initiative aims to strengthen national food security through the effective management of food reserves. This study analyzes the legal aspects of the Food Estate concept in Indonesia using a normative juridical approach, which includes a literature review, analysis of relevant laws and regulations, and an examination of legal cases related to the Food Estate program.The findings indicate that the legal framework governing the Food Estate program has undergone several revisions, beginning with Minister of Environment and Forestry Regulation No. 24 of 2020 and later amended by Minister of Environment and Forestry Regulation No. 7 of 2021. The Food Estate program presents both benefits and challenges. While it enhances food security, attracts investment, and increases farmers’ incomes, it also poses risks such as land conflicts, environmental degradation, deforestation, and shifts in agricultural practices that may threaten food sovereignty. Additionally, concerns arise regarding land conversion and the potential for price manipulation by financial stakeholders.

This study aimed to evaluate the landslide emergency management system at the Curug Cilember tourist site, Megamendung District, Bogor Regency, with a focus on the role of local community participation and optimization strategies based on ISO 45001 standards. A qualitative descriptive method was applied, using interviews, field observations, and literature studies, with purposively selected informants relevant to the research context. The results show that the emergency management system includes cross-sectoral planning, implementation through simulations and training, and regular evaluations involving community discussions. The findings highlight key supporting factors such as the presence of disaster-resilient village programs, while identifying obstacles including limited coordination, budget constraints, and low public awareness of landslide risks. Optimization strategies involve strengthening emergency communication, providing regular community-based training, improving evacuation infrastructure, and implementing ISO 45001-based procedures. In conclusion, the synergy between tourism managers, local communities, and visitors is essential to establish an effective and sustainable emergency response system that enhances disaster preparedness and community resilience.

The rapid expansion of urban populations and changing consumption behaviors have intensified solid waste challenges, particularly in developing countries like Indonesia. Used beverage cartons (UBCs), composed of layered paper, plastic, and aluminum, are among the most difficult packaging materials to recycle. Extended Producer Responsibility (EPR) is increasingly promoted as a policy mechanism to shift waste management responsibilities from local governments to producers. However, the implementation of EPR in Indonesia remains limited due to weak infrastructure, low market incentives, and fragmented stakeholder coordination. This study aims to identify strategic priorities for EPR implementation in managing UBC waste by applying the Analytical Hierarchy Process (AHP), integrated with a penta-helix stakeholder framework. Conducted in East Jakarta between March and November 2023, the research engaged five expert informants representing government, academia, industry, civil society, and waste management sectors. Through structured pairwise comparisons, the study evaluated five sub-criteria: stakeholder participation, regulatory framework, financial incentives, market access for recycled UBCs, and recycling technology. The AHP analysis revealed that stakeholder participation holds the highest priority weight (48.31%), followed by the regulatory framework (34.57%) and financial incentives (9.64%). Market and off-taker availability (5.63%) and recycling technology advancement (1.85%) were identified as lower-priority but still necessary components. These results indicate that socio-economic considerations dominate strategic decision-making in UBC waste management. The study offers a data-driven and context-sensitive framework for EPR implementation that can inform policymakers and industry actors. Furthermore, the AHP model demonstrates potential for replicability in other complex waste streams requiring coordinated multi-stakeholder engagement.

This study aims to assess Disaster Resilience Village (DESTANA) program has managed to enhance community resilience in the face of climate change impacts in Tambakreja Village, Cilacap Regency. The study utilized primary data collected through questionnaires and employed logistic regression analysis to examine the relationship between climate change, the DESTANA program, and community resilience. The results indicate that the DESTANA program positively impacts community resilience. However, the program's moderating role in the relationship between climate change and community resilience was not significant. This suggests that factors such as program implementation quality, community participation, and local context may influence the program's effectiveness. To enhance the impact of the DESTANA program, future research should explore the role of these factors in greater detail.

Peran Perhutani dan petani lokal dalam mengembangkan agroforestri di KPH Bogor penting dalam upaya mitigasi iklim berbasis penyerapan karbon. Areal yang luas di bawah kewenangan Perhutani dengan masyarakat lokal di sekitar kawasan tersebut membangun kemitraan berbasis agroforestri sebagai bagian dari pengelolaan hutan lestari. Perbedaan komposisi tanaman pada tujuh sistem agroforestri di KPH Bogor ditemukan pada masing-masing BKPH. Petani menyesuaikan tanaman multiguna yang ditanam dengan tanaman induk Perhutani yang lebih dominan. Stok karbon yang tersimpan di lahan agroforestri dapat meningkatkan pendapatan petani berdasarkan harga karbon, seperti nilai sosial dan ekonomi karbon. Potensi peningkatan karbon tahunan rata-rata yang dihitung berdasarkan stok karbon agroforestri di atas permukaan pada 7 petak contoh berkisar 2,26 – 66,65 ton CO2e per hektar, sedangkan pada 2 sistem lahan monokultur berkisar 13,65 – 18,29 ton CO2e per hektar. Peningkatan karbon dalam sistem pengelolaan lahan agroforestri lebih baik dibandingkan dengan hutan monokultur, karena memiliki keragaman tanaman dengan umur yang berbeda. Dari segi pendapatan karbon, semakin luas lahan agroforestri yang dikelola petani, semakin tinggi pula pendapatan karbon yang diterima. Dengan menggunakan metode transfer manfaat selama periode mitigasi 20 tahun, diperkirakan pendapatan meningkat 1,8 kali dari penjualan serapan karbon pada tingkat inflasi 3%.

Corruption in Indonesia's natural resource sector is a significant issue with far-reaching consequences for environmental sustainability. Despite the detrimental effects of corrupt practices on the environment, law enforcement penalties for corruption often fail to compensate for their environmental impact. The aim of the study is to explore how the use of Environmental Impact Assessments (EIAs) strengthens law enforcement efforts and increase penalties for corrupt practices in Indonesia's natural resource sector. The method used is to collect and analyze regulations, policies, and corruption study cases to examine the relationship between EIA and corruption penalties. The results showed that EIA can help corruption cases investigation and corruption cases involving EIA receive heavier penalties. This study concluded that the Indonesian government needs to reformulate its law enforcement approach by incorporating EIA into corruption investigations and using more severe penalties to deter corruption in the natural resource sector.

Oil palm smallholders, in particular non-plasma independent smallholders, experience significant yield gaps. Closing this yield gap is important to enhance sustainable livelihoods for oil palm smallholders and reduce the risk of yield increase through expansion. One of the key factors influencing yield is the harvest interval (number of days between two harvesting rounds). Although standards for Good Agricultural Practices regarding oil palm prescribe a harvest interval of 7-10 days, independent smallholders often maintain a harvest interval of 12-30 days. A longer harvesting interval not only reduces the number of fresh fruit bunch harvested per hectare per month but also leads to a larger harvest loss from overripe fruits falling to the ground, deteriorating quickly (harvest loss). We followed an interdisciplinary research approach, combining insights from agronomy and anthropology, to better understand farmersâ€™ practices, and drivers and challenges underlying decision-making. The approach consisted of field audits, farmer surveys, and qualitative interviews to explore which factors impact harvest interval. The harvest interval of smallholders in Riau and West Kalimantan ranged from 11 to 30 days. Farmers followed long harvest intervals (>16-d) due to the low fresh fruit bunch yield. However, longer harvest intervals increased potential harvest losses.
