Abstract

Transitioning toward a sustainable company is no longer an option but a necessity for the business entity to be agile in responding to sustainability issues. This study examines how an oil and gas company developed a program within the framework of Creating Shared Value (CSV) by bridging the local community and the resources with the company’s value chain. This study was conducted through a case study of the collaborative partnership between PT Pertamina EP Pendopo Field, an oil and gas company, and Sukakarya Village, STL Ulu Terawang Subdistrict, South Sumatra, Indonesia. The results indicate that the company’s initiative lies in developing a CSV prototype program that utilizes areca nuts as a pipe corrosion inhibitor to support the local economy and community empowerment. The company learned to work together with the Kelompok Wanita Tani Melati (Women’s Smallholder Group) and the local community to establish local business clusters. Challenges persist in three key areas: the learning activities related to areca nut extract production, the capacity of local institutions to serve as effective coordinators, and the establishment of cooperative mechanisms between the company and the community. Institutionally, the company has learned to navigate the intersection of sustainability and community-level socioeconomic development by reframing operational challenges concerning local social issues.

Abstract

Soil erosion represents a major environmental challenge, particularly in arid and semi-arid regions where natural factors and human activities intensify land degradation. This study evaluates the Soubella sub-catchment's susceptibility to water erosion using the MEDALUS (Mediterranean Desertification and Land Use) model. The assessment is based on four key quality indices Soil Quality Index (SQI), Climate Quality Index (CQI), Vegetation Quality Index (VQI), and Anthropogenic Quality Index (AQI) derived from remote sensing, GIS analysis, and field observations. Spanning 1837.33 km², the study region features diverse topography, with elevations ranging from 376 to 1871 meters and an average slope of 19.02 m/km, indicating moderate terrain. The climate is semi-arid, characterized by high temperatures, limited rainfall, and pronounced spatial and temporal variability. Average annual precipitation at the Soubella dam site is estimated at 289 mm. The findings reveal a distinct spatial classification into three erosion sensitivity levels: non-affected (27.5%), sensitive (16.1%), and highly sensitive (56.4%). The resulting erosion sensitivity map highlights the spatial distribution of vulnerable areas, demonstrating the significant roles of climate, topography, and land use in soil degradation. These insights are crucial for developing targeted and sustainable land management strategies to mitigate erosion risks in the region.Received: 2025-08-15 Revised: 2026-03-05 Accepted: 2026-04-14 Published: 2026-04-20

Abstract

 Despite the growing body of research on erosion risk management (ERM), a significant gap remains in studies specifically examining ERM through bibliometric analysis. This study bridges this gap by analyzing 81 ERM-related publications retrieved from the Scopus database using bibliometric techniques, VOSviewer, and Microsoft Excel. The analysis reveals that a limited number of prominent authors, affiliations, countries, and funding sources characterize ERM research. The United Kingdom dominates funding of ERM research, with the Environment Agency, Bristol, emerging as the organization with the most ERM-related publications, and India, aggregately, taking the lead as the country that is most associated with ERM research. The triad of Avanzi J.C., Curi N., and Viola M.R. has the most impactful works based on citation counts, with Catena having the reputation of the most cited journal concerning ERM research. A notable increase in ERM publications, post-COVID-19, suggests growing interest in sustainable development and risk assessment techniques like GIS.  Keyword Co-occurrence Analysis (KCA) identified four major research hotspots, which informed the identification of research gaps and future research directions. This study provides a foundation for further exploration of ERM and its potential to drive sustainable development.

Abstract

This study aims to delineate spatial conflict zones, assess navigational risk, and formulate geographic information system (GIS)-based design scenarios for a proposed eastern Inshore Traffic Zone (ITZ) in Sunda Strait which is a very important section of Archipelagic Sea Lane I (ALKI I) in Indonesia. International Maritime Organization (IMO) established a western ITZ in 2020, but the eastern sector lacked a systematic nearshore traffic scheme. This is due to the coexistence of competing activities such as fisheries, conservation zones, port access routes, and submarine infrastructure in a limited coastal corridor. Therefore, a spatially integrated method was adopted and combined with Automatic Identification System (AIS)-derived traffic density, longitudinal Vessel Traffic Services (VTS) deviation data, hydrographic maps, and Banten marine spatial planning (RZWP3K) layers in GIS overlay framework. AIS measurements showed that ferry crossings of 2,691–3,168 per month were significantly higher than the longitudinal Traffic Separation Scheme (TSS) flows reported as 365–576 per month and led to frequent crossing encounters in nearshore multi-use areas. The kernel density analysis also signaled that the interactions were concentrated east of TSS corridor specifically in Merak–Cigading waters and Sangiang Island. The two ITZ design possibilities assessed were the complete segregation model and a corridor-oriented layout. The corridor-based ITZ had enhanced spatial compatibility by reducing the overlap between reserve areas and underwater cable routes while augmenting navigational safety. The results showed that GIS-enabled spatial governance could improve traffic management by restructuring movement patterns rather than limiting navigation. This further led to the incorporation of navigational safety goals into maritime spatial planning across intricate archipelagic rivers.
