Abstract

The cocoa industry is undergoing complex market dynamics driven by increasing global awareness of sustainability issues. Sustainable entrepreneurship has emerged as a strategic approach to balancing economic performance, environmental protection, and social equity. This study aims to examine the key factors influencing the sustainability of the cocoa industry from a sustainable entrepreneurship perspective and to analyze its impact on economic, social, and environmental outcomes. A quantitative descriptive approach was employed, with data analyzed using Structural Equation Modeling (SEM). The results indicate that all measurement indicators exhibit outer loading values exceeding 0.70, confirming acceptable convergent validity. Sustainable entrepreneurship demonstrates a strong and statistically significant effect on the overall sustainability of the cocoa sector. Specifically, its application leads to enhanced business efficiency, improved social welfare, and greater adoption of environmentally responsible practices. Moreover, the high R² values for the sustainability constructs suggest that sustainable entrepreneurship serves as a major explanatory variable for performance across all three dimensions. These findings highlight the strategic role of sustainable entrepreneurship in fostering a resilient and sustainable cocoa industry. The implications provide valuable insights for policymakers, industry actors, and stakeholders in developing sustainability oriented cocoa agribusiness models.

Abstract

The ever-increasing demand for electrical energy demands alternative, environmentally friendly, and sustainable energy sources. Conventional batteries generally rely on synthetic chemicals that have the potential to pollute the environment. One solution that is beginning to be developed is the use of organic waste as an electrolyte source in bio-batteries. This review article discusses the potential of orange peel, fruit, and vegetable waste as a natural electrolyte containing organic acid compounds, particularly citric acid (C₆H₈O₇), as well as mineral acids that can decompose into ions in solution, thus conducting electricity. Various research results show that the acid and water content of organic waste can produce a potential difference when paired with dissimilar metal electrodes, thus generating an electric current. In addition, the pH characteristics and natural electrolyte content of the waste indicate its suitability as a substitute for hazardous chemicals in batteries. Thus, the use of orange peel, fruit, and vegetable waste has the potential to become an environmentally friendly bio-battery innovation that can support efforts to reduce dependence on conventional batteries while contributing to sustainable organic waste management.

Abstract

This study investigates the effectiveness of ecological management in supporting reclamation of tailings land at the Mile Post 21 Reclamation and Biodiversity Research Center, PT Freeport Indonesia. Using a qualitative descriptive approach, the research employs primary data obtained through interviews, documentation, and direct observation, complemented by secondary data from archives, reports, and company records. The analysis is guided by ISO 14001 environmental management principles, using a checklist method adapted from the Global Environmental Management Initiative (GEMI) to evaluate ecological, technical, socio-economic, and regulatory aspects of reclamation practices. Findings reveal that ecological management at Mile Post 21 has been highly effective, achieving more than 80% compliance with ISO 14001 indicators. Vegetation cover increased from less than 10% to over 75%, with more than 160 planted species complemented by natural succession involving over 500 species. Soil quality improved significantly, with organic carbon rising from <0.5% to 2.5%, pH levels increasing toward neutrality, and cation exchange capacity reaching medium–high levels. These changes facilitated the restoration of ecological functions and supported biodiversity recovery. Moreover, reclaimed land has been transformed into productive agricultural areas integrating crops, livestock, and aquaculture, providing socio-economic benefits for local communities and involving indigenous landowners in sustainable management. Despite technical challenges related to poor soil properties and managerial constraints such as long-term funding, the program demonstrates that ecological management, when implemented systematically under ISO 14001, can effectively restore degraded post-mining land into ecologically resilient and socially beneficial systems.

Abstract

Coastal abrasion poses a significant threat to Indonesia, an archipelagic nation with one of the world’s longest coastlines. The phenomenon is particularly severe in Napabalano District, Muna Regency, where dense settlements, economic activities, and declining mangrove ecosystems increase exposure to erosion hazards. This study aims to assess the risk of coastal abrasion in Napabalano District using a GIS-based approach aligned with the Indonesian National Disaster Management Authority (BNPB) framework. Primary data, including GPS coordinates, satellite imagery, and field surveys, were integrated with secondary data such as demographic statistics, oceanographic parameters, and historical records of abrasion events. Spatial analysis in ArcGIS was employed to evaluate vulnerability, capacity, hazard, and disaster risk indices. Results show that all villages in Napabalano District fall into the high-risk category, with Napabalano and Napalakura recording the highest risk values due to concentrated populations, limited mangrove protection, and inadequate disaster management capacity. Social and economic vulnerabilities, including high poverty ratios and dependence on coastal livelihoods, exacerbate exposure, while institutional capacity remains critically low, marked by weak early warning systems and limited community preparedness. Mitigation strategies proposed include mangrove rehabilitation, strict coastal zoning enforcement, community-based disaster preparedness programs, and the establishment of effective early warning systems. These findings highlight the urgent need for integrated, multi-stakeholder approaches to strengthen resilience against coastal abrasion. The study provides a strategic basis for local government and community planning in managing and reducing the impacts of coastal hazards in Napabalano District.

Abstract

Electricity demand in Indonesia is increasing along with economic and population growth. The plan to build a nuclear power plant (NPP) in Kalimantan needs to be accompanied by support facilities such as disposal. Research on disposal facilities in West Kalimantan is crucial because of its proximity to the planned NPP, and using local materials like kaolin and clay will be more economical. In this study, compacted clay and kaolin layers were used as part of the engineered barrier at the disposal site. The goal is to prevent the release of Cs-137 from the facility into the unsaturated zone. XRD, XRF, and ICP-OES were used to characterize the clay and kaolin studied. Analysis revealed many absorbent minerals suitable for the engineered barrier at the disposal site.To evaluate the diffusion coefficient (Da) of Cs-137 in compacted clay and kaolin samples, a vertical diffusion model was employed. The diffusion coefficient was measured in a diffusion column unit with varying times and densities. Fick's law equation was used to calculate the Da value for the samples. The results showed that the diffusion coefficient for kaolin ranged from 2.75 x 10-12 to 3.96 x 10-12 m²/s, and for clay from 1.62 x 10-12 to 2.92 x 10-12 m²/s. In clay and kaolin samples, density affected the diffusion rate; higher density resulted in a lower Da value. However, time did not impact the Da value. The diffusion coefficient in kaolin was twice as fast as in clay samples.In the safety assessment experiment with RESRAD Offsite, a 0.2 m kaolin layer was sufficient.
