Rising atmospheric CO₂ emissions from fossil fuel-based industries have intensified the need for effective mitigation strategies, with Carbon Capture and Storage (CCS) in geological formations, particularly un-mined coal seams necessitates specialized research into numerous critical factors that are equivalent thorough characterization of coal properties such as porosity, permeability, uniaxial compressive strength (UCS), poisson ratio, and brittleness. This study serves as a preliminary assessment of the CCS potential of Coal Seam D in the Suban Burung Block, South Sumatra Basin, using drilling data from four wells (within area 960 m × 860 m). This study aims to describe the coal seam D strata for underground CO2 storage. Coal Seam D was identified from core sample data, with laboratory analyses conducted to determine density and porosity values. Then, in this study we predict velocity (Vp and Vs), UCS values, and BI using petrophysical and rock physics approaches. The analysis by integrates well correlation, estimation of elastic and mechanical parameters, and spatial interpolation of petrophysical properties. Results indicate that Coal Seam D has a thickness of 8.1–10.7 m and porosity ranging from 0.14–0.198. Mechanical properties show Uniaxial Compressive Strength (UCS) values of 9.5-9.7 MPa and a Brittleness Index 0.47–0.50 which indicate coal with low to medium strength and medium brittleness. Based on the preliminary analysis, the coal seam D in this region exhibits favorable candidate for implementation CO₂ storage in South Sumatra, Indonesia.

Regional inequality remains a regional development problem in Southern Sumatra, particularly in the provinces of Lampung, South Sumatra, and Bengkulu. Differences in the level of infrastructure development between regions lead to unequal economic development and public welfare. Education, health, road, and sanitation infrastructure are important factors influencing the level of regional inequality because they are related to public access to basic services and economic activities. This study aims to analyze the effect of education, health, road, and sanitation infrastructure development on regional inequality among the three provinces of Southern Sumatra in 2019–2023. This study uses quantitative methods with secondary data obtained from the Central Statistics Agency (BPS). Data analysis was conducted using panel data regression with the Random Effect Model (REM) approach through the RStudio application. Regional inequality was measured using the Williamson Index as an indicator of inter-regional development disparities. The results show that education infrastructure has a positive and significant effect on regional inequality. Health infrastructure has a negative and significant effect on regional inequality. Meanwhile, road and sanitation infrastructure have a negative but insignificant effect on regional inequality. These findings indicate that health infrastructure development can help reduce regional disparities, while unequal education development actually increases inequality between regions. Meanwhile, road and sanitation infrastructure development has not had a strong impact on reducing regional inequality during the study period. The study concludes that equitable infrastructure development, particularly in the education, health, road, and sanitation sectors, needs to be continuously improved to ensure more equitable development between regions and reduce regional inequality in Southern Sumatra.

Giant featherback (Chitala lopis) is an ancient species of freshwater fish considered globally extinct until extant populations were re-discovered in the Sundaland region of Indonesia in 2022. To improve management of the remaining populations, this study used genomic DNA and landmark-based geometric morphometric analyses of fish scales to evaluate whether these approaches can discriminate among phylogenetic clades, sexes and broad habitat ecotypes inhabited by extant C. lopis populations. DNA analyses of 39 specimens from eight rivers provided the first evidence of two phylogenetic clades: (i) those from Central and South Borneo and (ii) those from West Borneo, Riau, South Sumatra and Jambi. Scale morphology was characterised across eight body areas using scale dimensions (relative height and width to standard length and height-to-width ratio), centroid size and Procrustes shape coordinates, with repeated-measures structure accounted for using linear mixed models and Procrustes ANOVA with a randomised residual permutation procedure (RRPP). Scale dimensions and centroid size varied significantly among body areas (all p < 0.001), with lateral and dorsal regions bearing the largest scales and the pectoral region the smallest. Clade membership had a small but significant effect on relative scale height (H/SL; β = -0.44, p = 0.024), with Clade 2 individuals consistently showing lower values than Clade 1, though scale geometry overall showed limited promise as a rapid non-destructive stock discriminator. Both clade and sex had small but significant effects on Procrustes scale shape (R2 = 0.015 and 0.013, respectively; both p = 0.001), while phenotypic trajectory analysis revealed that males exhibited a significantly greater amplitude of scale shape change across body positions than females (trajectory magnitude: M = 0.289, F = 0.207; p = 0.034), despite both sexes following parallel shape trajectories along the body axis. These results provide a novel morphometric baseline for C. lopis and highlight the importance of body-position-specific and multivariate approaches when characterising scale morphology in endangered freshwater fishes.

This study proposes an Effectiveness Index (EI) that integrates inspection coverage, targeting accuracy, and risk derived from Weigh-In-Motion (WIM) data to assess vehicle overloading control. Using data from 6.054.617 vehicles during the observation period from November 2023 to July 2025 in South Sumatra, the index was applied to two enforcement units. Results show that Unit Kertapati achieved a moderate effectiveness score of 43.6, while Unit Talang Kelapa was classified as ineffective with a score of 6.7. The analysis reveals that increasing inspection coverage yields a higher marginal gain in effectiveness than improving targeting accuracy alone. This EI framework offers a scalable, data-driven tool for benchmarking performance and optimizing resource allocation in vehicle overloading control.

Planning for road network development in swampy areas is inseparable from determining road trace to obtain a suitable road network layout. The suitability of geological, topographic, soil, hydrological and land use conditions is a matter that must be considered, coupled with other issues such as land value, land ownership, social and economic impacts, and identification of environmentally sensitive areas. There are nine components that are considered in determining road trace in swamp areas in order to obtain environmentally sound road construction, namely: soil texture, puddle, CBR value, peat soil, land use, average daily traffic, tonnage, accessibility, and sociogeography. This study aims to obtain a road trace in an environmentally friendly swamp area using a road trace model in swamp areas developed by Indrayani, et al in 2019. The application was carried out in the swamp area of Banyuasin district, South Sumatra province, by taking the 9 components in the recommendation. The method used in this research is remote sensing in the introduction of the physical environment, while the scoring and weighting methods use multicriteria spatial analysis in determining the suitability of the area.. From the modeling results, it is found that the suitable area for road alignment is 136.66 km2, which is quite suitable for 3151.66 km2, and which is very inappropriate is 39.71 km2. Meanwhile, the road alignment that connects between districts in the study area is obtained in the form of a thematic map.

Production is increasingly shifting into village territories as a result of rural industrialization, leading to an uneven distribution of socio-ecological risks. This article examines how such manufactured risks arise and how women enact reflexivity in Bakung Village, South Sumatra. Using a qualitative descriptive design embedded in participatory action research, we combined in-depth interviews, focus group discussions, participant observation, and community social mapping to diagnose exposure pathways and responses. Findings reveal hamlet-specific configurations: domestic water contamination linked to tapioca effluent in Dusun 1; persistent dust and noise from a coal haul corridor disrupting livelihoods in Dusun 2; and cross-boundary particulates from a wood processing plant affecting Dusun 3. Women lead proactive contention—demonstrations, petitions, monitoring, and visual documentation—while developing adaptive micro-infrastructures such as household filtration, interior dust barriers, and intensified hygiene. Institutional responses were largely compensatory and reactive, reducing immediate burdens without addressing structural drivers. The research offers a gendered, community-driven viewpoint to discussions on risk society, illustrating how delocalized threats are made apparent through participatory mapping and how adaptation expenses are individualized at the household level. Enforced setbacks, cumulative impact assessment, independent monitoring with public dashboards, and stakeholder forums involving affected villages are among the implications of industrialization.

Apis dorsata Fabricius is a giant forest honey bee with a wide distribution that includes Indonesia. South Sumatra, Belitung, and West Kalimantan exhibit distinct geographic and ecological characteristics that may influence the morphometric variations of this species. This study aimed to analyze the similarities and differences across various morphometric parameters of A. dorsata colonies from these three regions. A traditional morphometric approach was conducted to measure 23 morphometric parameters. A total of 120 individuals from 12 A. dorsata colonies originating from South Sumatra, Belitung, and West Kalimantan were examined. The results indicated that 12 of the 23 parameters (52.2%) differed significantly among populations. Populations from South Sumatra generally exhibited larger structural dimensions across several head, thorax, and wing parameters, whereas the Belitung populations demonstrated higher values for proboscis length and antennal socket distance. Multivariate analysis (NMDS and ANOSIM) revealed statistically significant, albeit weak, differentiation among the populations. Overall, these findings indicate the presence of localized morphometric variations across the islands, although the degree of morphological differentiation remains relatively low.

Food is a priority human need for survival. The evaluate population's level of food security in Ogan Komering Ulu (OKU) Regency, South Sumatra. This study includes mapping and measuring food vulnerability based on the main indicators: availability, accessibility, and food utilization. The purposive sampling method was used to select the research location, which covers 157 villages and 13 sub-districts in OKU Regency. Primary data were obtained through field observations and surveys, while secondary data were obtained from various official sources. The results showed that the Food Security Index (IKP) of OKU Regency was in the moderate category, with variations in the level of food security in each sub-district. The vast agricultural land increases food availability, but low nutritional awareness and stunting rates in children challenge good food accessibility and utilization. In addition, the analysis found groups of people vulnerable to food insecurity, especially in remote areas. These findings will help policymakers create better strategies to address food security issues in the OKU Regency.

HIGHLIGHTS The survival rate of cervical cancer patients at Dr. Mohammad Hoesin Hospital was significantly higher for those undergoing surgery combined with chemotherapy or chemoradiation, with a median survival of 87.5% at 36 months, compared to other treatments such as chemotherapy or radiation alone. The loss to follow-up rate among cervical cancer patients at Dr. Mohammad Hoesin Hospital decreased over three years but remained high at 62%, with patients over 51 years old and those living far from healthcare facilities being more likely to miss follow-up appointments. ABSTRACT Objective: To describe survival patterns and associated clinical factors among cervical cancer patients treated at a tertiary referral hospital in South Sumatra over a three-year period. Materials and Methods: This retrospective cohort study analyzed cervical cancer patients diagnosed and treated at Dr. Mohammad Hoesin General Hospital, Palembang, Indonesia, between January 2021 and December 2023. A total of 494 patients (59 in 2021, 156 in 2022, and 279 in 2023) meeting the inclusion criteria were selected through total sampling. Survival analysis was conducted using the Kaplan-Meier method, and outcomes were stratified by stage, histopathological type, and treatment modality. Results: The median age of patients was 51 years, with most classified as multiparous and presenting at stage III (68.2%). Squamous cell carcinoma was the most common histopathological type (75.3%). The overall 3-year survival rate was 70.8%, with stage-specific survival rates of 82.8% (stage I), 78.2% (stage II), 70.3% (stage III), and 48.8% (stage IV). Survival was higher in patients with squamous cell carcinoma (74.5%) compared to those with adenocarcinoma (57.3%). Combination therapies, particularly surgery with chemoradiation (87%), resulted in better outcomes than monotherapies such as radiotherapy alone (28.1%). However, the study also reported a high loss to follow-up rate (62%), which may impact long-term survival evaluation. Conclusion: Survival patterns among cervical cancer patients in South Sumatra are strongly influenced by cancer stage, histological subtype, and treatment approach. Multimodal treatments were associated with improved survival, emphasizing the need for early diagnosis and comprehensive care. Addressing the high rate of loss to follow-up is essential for improving long-term outcomes in this population.

This study aims to analyze the effect of deforestation, the number of industries, and the level of urbanization on the Environmental Quality Index (IKLH) in the provinces of South Sumatra Region (Jambi, South Sumatra, Bengkulu, Lampung, and the Bangka Belitung Islands) from an Islamic economic perspective. This research uses a quantitative method with secondary data in the form of panel data from 2015 to 2024. The sampling technique used was saturated sampling with 5 provinces as cross-sectional units over 10 years, resulting in 50 observation data points. The data were analyzed using panel data regression analysis. The model selection tests (Chow and Hausman tests) indicated that the Fixed Effect Model (FEM) is the most appropriate. The results partially show that the number of industries has a negative and significant effect, and the level of urbanization has a positive and significant effect on the IKLH. Meanwhile, deforestation has a negative but insignificant effect on the IKLH at a 95% confidence level. Simultaneously, deforestation, the number of industries, and the level of urbanization have a significant effect on the IKLH in the South Sumatra Region. In the perspective of Islamic economics, these findings emphasize the importance of the principles of balance (tawazun), preventing damage (dar'u al-mafasid), and moral supervision (hisbah) in managing natural resources for the creation of public welfare (maslahah).

AH-052 well, which uses a Sucker Rod Pump (SRP), began to experience a decline in productivity over time. The performance of the AH-052 oil well in South Sumatra, which uses a Sucker Rod Pump (SRP) as an artificial lift system. This well has a depth of 289.87 meters with a perforation interval of 236.52–238.05 meters. Before optimization, this well showed a production rate of 264 BFPD with a water cut of 97% and a pump efficiency of only 72.28%. Through variations in the SRP pump system parameters, the available equipment specifications were 1 1/4 inch and 1 1/8 inch rods, rod number 109, plunger 2 inch, stroke length (SL) of 140 inch, and pump speed (n) of 5 spm. The parameters used successfully increased pump efficiency significantly to 91.12% and production rate to 381.2 BFPD. Economic feasibility analysis based on the Production Sharing Model Contract Cost Recovery contract model showed very positive results. This project generated a Net Present Value (NPV) of MU$202.08, an Internal Rate of Return (IRR) of 1153%, a Pay Out Time (POT) of 0.086 years, and a Profitability Index (PI) of 22.56. Based on these indicators, this optimization project is considered highly financially viable and provides substantial benefits.

Stunting represents a critical global health challenge, particularly in low- and middle-income countries, due to its impact on child development and long-term economic productivity. Despite national efforts in Indonesia, stunting remains prevalent and necessitates localised studies to address this issue. This study aimed to examine factors associated with stunting in rural South Sumatra, Indonesia. A cross-sectional study involving 348 respondents was conducted across 11 villages in Musi Rawas Regency, South Sumatra. Data were analysed using logistic regression to identify the dominant risk factors. Maternal knowledge during pregnancy was significantly associated with stunting prevention, with mothers having lower knowledge showing higher odds of poor preventive practices (OR=1.663; 95% CI=1.149-1.857; P=0.007). Postnatal maternal knowledge also remained a significant predictor (OR=1.479; 95% CI=1.036-2.112; P=0.031). In contrast, maternal attitudes during pregnancy (P=0.356) and after childbirth (P=0.109) were not significantly associated and were not retained as predictors in the final model. Maternal knowledge, education, and attitudes are pivotal in preventing stunting. Targeted interventions aimed at improving maternal education, awareness and attitudes are essential to mitigating stunting in rural South Sumatra.

This study examines the relationship between budgetary participation and budget goal clarity on organizational performance, with organizational commitment serving as a mediating variable. The research is conducted within the National Narcotics Agency (BNN) in South Sumatra Province, Indonesia, which plays a strategic role in implementing drug prevention and eradication programs. The study adopts a quantitative approach using survey methods, with data collected from 110 respondents involved in budgeting and planning processes. The data are analyzed using Partial Least Squares–Structural Equation Modelling (PLS-SEM). The results indicate that budgetary participation does not have a direct significant effect on organizational performance but exerts a significant indirect effect through organizational commitment. In contrast, budget goal clarity has a positive and significant effect on organizational performance both directly and indirectly. Furthermore, both budgetary participation and budget goal clarity significantly influence organizational commitment, which in turn positively affects organizational performance. These findings highlight the critical role of organizational commitment in strengthening the effectiveness of budgeting practices in the public sector. This study contributes to the literature on public sector performance management by integrating Agency Theory and Goal-Setting Theory to explain the mechanisms linking budgeting practices and performance outcomes. Practically, the findings suggest that public organizations should enhance employee involvement in budgeting processes and ensure clarity in budget targets to improve commitment and performance.

This study assesses coal and overburden production efficacy for the mining sequence at Pit Rista, PT Dewa Sukses Mandiri, South Sumatra, during July and August 2025, and recommends operational enhancements to facilitate production objectives in the following months. The investigation was prompted by the inability to meet monthly production targets, as evidenced by insufficient effective working hours, excessive downtime, low equipment availability, and discrepancies between planned and actual mining progress. A quantitative evaluative method was employed utilizing primary data consisting of loading and hauling cycle durations, alongside secondary data such as production reports, working hours, downtime records, mine design, and mining sequence plans. The examination encompassed equipment productivity, job efficiency, match factor, physical availability (PA), use of availability (UA), Pareto analysis of downtime, and a comparison between planned and actual implementation of the mining sequence. The findings indicate that production deficits in July and August 2025 were mostly attributable to diminished effective working hours resulting from operational and mechanical delays, low PA and UA values, and discrepancies between the planned mining sequence and actual field execution. In July, the primary cause of lost time was the lack of hauling help, however in August, weather-related delays emerged as the principal limitation. These conditions impeded mining advancement and diminished overall output efficacy. In light of these findings, production optimization should prioritize enhancing mining sequence execution, reinforcing equipment maintenance and oversight, reconfiguring pit front and haul road geometry, and regulating haul road gradients to minimize downtime and enhance operational efficiency.

Objective: Drawing on ethical leadership and organizational justice theory, this study examines how justice is enacted through leadership practices in private Islamic higher education institutions in South Sumatra, Indonesia. Method: Adopting a qualitative multiple-case study design, data were collected through in-depth interviews with institutional leaders and lecturers, supported by document analysis. Results: The findings reveal that perceptions of fairness are shaped less by distributive outcomes than by procedural justice embedded in governance practices. Ethical leadership emerges as a key mechanism enabling justice through transparency, consistency, and moral justification in decision-making processes, even under conditions of financial and structural constraint. Conversely, misalignment between ethical rhetoric and enacted practices generates ethical dissonance and undermines leadership legitimacy. Novelty: Justice in higher education governance is increasingly recognized as a critical ethical concern, particularly in relation to leadership practices that shape budget management, workload distribution, and reward systems. This study contributes to ethical leadership theory by repositioning ethical leadership as a governance capability rather than an individual moral trait, and extends organizational justice research by highlighting the primacy of procedural justice in resource-constrained academic environments. By offering contextually grounded insights from faith-based higher education institutions in the Global South, the study addresses a significant gap in the predominantly Western-centric literature on leadership and justice in higher education.

FABA production in South Sumatra reaches 1.2–1.8 million tons annually, yet landfill disposal dominates and causes significant environmental impacts (LCA score: 40.29). The reclassification of FABA as non-hazardous waste under Government Regulation No. 22/2021 creates utilization opportunities; however, evidence-based regional policies remain limited. This research examines the integration of LCA and policy analysis to formulate recommendations for sustainable FABA management in South Sumatra. A convergent parallel design was applied, using LCA to compare landfill, paving block, and compost scenarios, and AHP involving 33 stakeholders to prioritize policy criteria and alternatives. LCA results show that compost has the lowest environmental impact (5.62), followed by paving blocks (~18.00) and landfill (40.29). AHP prioritizes environmental (32.0%) and social (24.5%) aspects, with compost as the top alternative (46.5%). The LCA–AHP integration indicates strong alignment between scientific evidence and stakeholder preferences. Based on these results, policy recommendations are proposed across short-, medium-, and long-term horizons, supported by a stakeholder responsibility matrix to ensure effective implementation. The study provides integrated policy recommendations and supports circular economy development, multi-criteria decision-making, and SDGs 12, 13, and 15, positioning South Sumatra as a potential model for sustainable FABA management

This study aims to determine: (1) the effect of organizational commitment, work motivation, and compensation on the performance of marketing employees at Bank Syariah Indonesia in the South Sumatra and Bangka Belitung regions; (2) the effect of organizational commitment on the performance of marketing employees; (3) the effect of work motivation on the performance of marketing employees; and (4) the effect of compensation on the performance of marketing employees at Bank Syariah Indonesia in the South Sumatra and Bangka Belitung regions. This research is an associative study. The variables examined in this study include organizational commitment, work motivation, compensation, and employee performance. The population consists of all marketing employees at Bank Syariah Indonesia in the South Sumatra and Bangka Belitung regions, totaling 101 employees. The sampling technique applied was proportionate stratified random sampling. Primary data were collected using questionnaires. The data were analyzed using multiple linear regression. The results indicate that: (1) organizational commitment, work motivation, and compensation have a significant effect on the performance of marketing employees at Bank Syariah Indonesia in the South Sumatra and Bangka Belitung regions; (2) organizational commitment has a significant effect on employee performance; (3) work motivation has a significant effect on employee performance; and (4) compensation has a significant effect on the performance of marketing employees at Bank Syariah Indonesia in the South Sumatra and Bangka Belitung regions

This policy study is motivated by the low accessibility of religious services for Christians in marginalized areas of South Sumatra Province, characterized by a chronic gap in the ratio of religious instructors to religious teachers. The main problem focuses on the distribution of functional personnel, which is centralized in urban areas, while transmigration and coastal areas experience a lack of sustainable education and spiritual guidance services. This study uses a descriptive qualitative methodology with a policy evaluation approach modeled after William N. Dunn, which includes criteria for effectiveness, efficiency, adequacy, equity, responsiveness, and technical feasibility. Using the Urgency, Seriousness, and Growth (USG) scoring technique, it was found that the inequality in human resource distribution is the most pressing issue requiring immediate intervention. The analysis results indicate that conventional recruitment mechanisms fail to address the extreme geographic barriers in South Sumatra. Therefore, this study recommends policy engineering through the implementation of a "Cluster System" or Integrated Religious Service Unit. This scheme legalizes the accumulation of teacher and instructor workloads across locations within a single service zone to fulfill administrative requirements for civil servants and professional allowances. Through this regulatory transformation, it is hoped that the problem of the small number of students at one coordinate point can be overcome, so that the state can guarantee the fulfillment of citizens' constitutional rights to embrace religion and receive proper religious education without being hampered by spatial and administrative limitations.

This study aims to develop information literacy teaching materials based on South Sumatra’s local wisdom that are valid, practical, and effective in enhancing junior high school students’ 21st century skills specifically critical thinking, creativity, communication, and collaboration. A Research and Development (R&amp;D) approach was employed using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The subjects were eighth-grade students at SMP Negeri 1 Tanjung Lubuk. Data were collected through expert validation sheets, teacher and student response questionnaires, observation sheets, and learning outcome tests. Expert validation by material, media, and language specialists confirmed the teaching materials as highly valid. Practicality testing yielded very positive responses from both teachers and students. Effectiveness evaluation, based on improved learning outcomes and 21st century skills assessment, demonstrated effective to highly effective categories. The research innovatively integrates indigenous South Sumatra local wisdom into information literacy instruction, creating culturally responsive pedagogy that simultaneously develops essential 21st century competencies. The validated teaching materials provide educators with ready-to-use, contextually relevant resources for cultivating information literacy while preserving and transmitting regional cultural heritage. This study contributes a replicable development model demonstrating how local wisdom can be systematically embedded within modern competency-based curricula, bridging cultural preservation with future-ready skill development.

Forest and land fires remain a persistent environmental challenge in South Sumatra, Indonesia, despite the implementation of the Zero-Burning Land Management Policy. This study examines the dynamics of network governance in the implementation of the policy by integrating Social Network Analysis (SNA) and in-depth interviews within a mixed-method framework. The research aims to analyze the structure of governance networks, coordination mechanisms, conflict and power dynamics, and adaptive responses among key actors, including provincial and district governments, plantation companies, NGOs, and local communities. The findings reveal a moderately centralized governance structure, with the provincial government acting as the dominant coordinating entity. While the network exhibits characteristics of a lead organization model, horizontal collaboration—especially in operational coordination—is also evident. Formal mechanisms such as inter-agency meetings and integrated task forces are complemented by informal coordination based on trust and personal relationships. However, the network is influenced by unequal capacities, resource imbalances, and overlapping authorities, which affect the stability and effectiveness of collaboration. The research also identifies adaptive responses, including the formation of integrated task forces, technology-based fire monitoring systems, and adjustments to local regulations. While these responses demonstrate institutional flexibility, adaptation remains largely reactive to crises rather than being integrated into systematic learning processes. Theoretically, the findings contribute to adaptive network governance by highlighting the interdependence of network structure, coordination quality, and adaptive capacity in environmental policy. For developing countries facing ecological pressures, strengthening trust, data integration, and institutional continuity is key to improving policy resilience and long-term fire prevention effectiveness.
