ne of the key challenges in supporting EV adoption is the provision of accessible charging infrastructure, which is closely related to user perception of acceptable service distance. This study aims to determine the optimal service distance of Electric Vehicle Charging Stations (EVCS) based on user preferences in Pekanbaru City, Indonesia, and to explore its implications for spatial planning. A quantitative approach was employed using a questionnaire survey of 51 respondents distributed across 15 administrative districts. All respondents were non-EV users, representing potential adopters in the early stage of transition. The survey captured preferred EVCS distance using interval-based categories, along with respondents’ awareness and intention toward EV adoption. The results indicate that the dominant preferred distance falls within the 2–4 km range, with an estimated mean of 3.08 km and a standard deviation of 1.98 km, resulting in an effective range of approximately 1–5 km. Considering urban road network constraints and detour factors, this range is further adjusted to 3–6 km to reflect more realistic travel conditions. These findings suggest that a relatively dense and accessible charging network is required to reduce range anxiety and support EV adoption. From a spatial planning perspective, a 4 km service threshold is proposed as a practical reference for EVCS deployment, representing the central tendency of user preferences within the adjusted range. This study highlights the importance of integrating user-based spatial parameters into infrastructure planning and contributes to the literature by emphasizing the role of perceived accessibility in shaping EV infrastructure demand in developing urban contexts.

the effect of deep breathing relaxation techniques on lowering blood pressure in elderly people in Bate Linteng and Lambunot Villages, Aceh Besar. This quantitative study used a pre-experimental design using a one-group pretest-posttest. The study was conducted from August 26 to August 31, 2024, with a population and sample of 16 elderly respondents with a history of hypertension. Data collection was conducted through observation using an observation sheet and the provision of deep breathing relaxation techniques. The results showed that the average blood pressure before the intervention was 148/90 mmHg with a standard deviation of 9.674, while after the intervention, it decreased to 143/87 mmHg with a standard deviation of 9.050. The statistical test results using the Paired Sample t-Test showed a significance value of 0.000 (p < 0.05), indicating a significant effect between deep breathing relaxation techniques and blood pressure reduction. The results of this study are expected to provide information for hypertension sufferers and their families that deep breathing relaxation techniques are a form of non-pharmacological therapy that can be performed independently to control blood pressure.
Abstract:Laboratory testing plays a crucial role in supporting patient diagnosis and monitoring; therefore, accurate and precise results are essential through the implementation of quality control (QC). Potassium level testing is…
one of the key parameters requiring robust quality control because it is closely linked to patients’ clinical conditions. This study aims to analyze the implementation of QC in potassium level testing using the EasyLyte device at the Kasih Ibu Hospital Laboratory in Surakarta. The research method used was quantitative descriptive with an observational approach using secondary data from QC results for the period from September to November 2025. Analysis was performed by calculating the mean, standard deviation (SD), coefficient of variation (CV), and evaluating the Westgard rules. The results showed that the CV values for normal and abnormal controls were within acceptable limits (≤5%), and no violations of any Westgard rules were found. This indicates that the test results have good precision and there are no deviations, either random or systematic. Overall, the analytical system is in control and the instrument performance is stable. Thus, potassium testing using the EasyLyte instrument meets quality requirements and is suitable for use in laboratory services, while still requiring QC monitoring as well as routine maintenance and calibration.
Abstract:This study aims to analyze the level of conformity of carbon emission disclosure based on Environmental Management Accounting (EMA) through the GRI 305 standard in companies included in the IDX LQ45 Low Carbon Leaders (LQ45LCL)…
Q45LCL) index during the period 2022–2024. The increasing global attention to Environmental, Social, and Governance (ESG) issues encourages companies to improve transparency in environmental reporting, particularly regarding carbon emissions. EMA plays an important role as an internal accounting system that provides environmental information used in sustainability reporting. However, variations in the quality of carbon emission disclosure among companies indicate that the implementation of EMA is not yet fully optimal. This research uses a quantitative descriptive approach by analyzing the level of disclosure conformity of GRI 305 indicators in sustainability reports of companies included in the IDX LQ45 Low Carbon Leaders index. The level of conformity is calculated by comparing the number of disclosed indicator criteria with the maximum number of criteria that should be disclosed. The classification of disclosure levels includes not applied, limited disclosure, partially applied, well applied, and fully applied. The results show that the level of carbon emission disclosure among companies varies across the observation period. Several companies demonstrate an increasing trend in disclosure, while others experience fluctuations or remain at a limited disclosure level. Overall, most companies fall within the partially applied category, indicating that carbon emission disclosure has not yet been comprehensively implemented according to the GRI 305 standards. These findings suggest that although companies in the LQ45LCL index are recognized as low-carbon leaders, improvements in the implementation of Environmental Management Accounting are still needed to enhance the transparency and completeness of carbon emission reporting.

e availability of competent and standardized laboratory human resources (HR). Polymerase Chain Reaction (PCR) testing has become the primary diagnostic method for pathogen detection, both in routine services and in public health emergency situations. The development of a PCR training curriculum and modules by the Center for Health Biology Laboratory (BBLBK) represents a strategic step toward standardizing the competencies of laboratory personnel. This article aims to describe the urgency of implementing certified PCR training policies as part of a national system for enhancing the competence of health laboratory human resources. The writing method employs policy analysis based on document review and the framework of national health regulations. The analysis results indicate variations in laboratory personnel competencies, the absence of a national certification scheme, limited availability of trainers, and the need for continuous curriculum updating. Certified PCR training is therefore recommended as a national instrument for fulfilling competency standards in health laboratories. The integration of training into the health human resource development system, along with the strengthening of quality- and safety-based approaches, is key to the successful implementation of this policy.
Abstract:This study aims to develop a technically compliant and economically feasible design for a Restricted Security Area (RSA) perimeter fence surrounding Substation 7, the Chiller facility, and the Ground Water Tank (GWT) at…
Kertajati International Airport. These facilities constitute critical operational infrastructure supporting electricity distribution, terminal cooling systems, and water supply, including fire suppression reserves. Field observations identified the absence of a regulation-compliant perimeter protection system, exposing the utility cluster to unauthorized access and operational risk. The research employed a quantitative descriptive–analytical approach integrating field measurement, engineering design modeling, volume computation, and cost estimation based on the 2024 Majalengka Regional Standard Unit Price. Technical evaluation referred to national aviation security regulations and ICAO Annex 17 principles. A BRC (British Reinforced Concrete) fence system with a total height of 3.20 meters (2.40 m fence body and 0.80 m concertina wire) was proposed. The structural configuration includes reinforced concrete isolated footings, tie beams (sloof), and a bottom plinth beam to ensure lateral stability and anti-climb resistance. The total perimeter length of 313.74 meters ensures complete enclosure of the critical facilities. The estimated total project cost amounts to IDR 509,553,000.00, including VAT. The results demonstrate that the proposed design is structurally reliable, regulation-compliant, and economically justified within a risk mitigation framework. The study contributes a replicable engineering and financial planning model for strengthening airport critical infrastructure protection and enhancing long-term operational resilience.
Abstract:This study examines the effect of financial performance and Corporate Social Responsibility (CSR) on firm value in cement companies listed on the Indonesia Stock Exchange (IDX) during the period 2020–2024. Financial performance…
rformance is proxied by Return on Assets (ROA), while firm value is measured using Price to Book Value (PBV). CSR is measured through a disclosure index based on the Global Reporting Initiative (GRI) Standards using content analysis. This research employs a quantitative associative approach with secondary data obtained from annual reports and sustainability reports of seven cement companies. Multiple linear regression analysis is used to test the hypotheses. The results indicate that ROA has a positive and significant effect on firm value, suggesting that efficient asset utilization enhances market perception. CSR disclosure also shows a positive and significant effect on firm value, supporting the legitimacy theory that socially responsible practices strengthen corporate reputation and investor confidence. These findings highlight the importance of integrating financial performance and sustainability strategies to enhance firm value, particularly in capital-intensive and environmentally sensitive industries such as cement.
Abstract:In facing global sustainability challenges, consumers play a strategic role in shaping the direction of the circular economy. This article presents a literature review on the relationship between consumer protection and…
the transition toward a sustainable consumption model. The main focus is directed at three key issues: the right to environmental information, the right to repair, and regulatory challenges related to greenwashing practices. By using a narrative literature review approach, this article examines various academic and policy sources to evaluate the extent to which consumer protection has been integrated into circular economy strategies. The findings show that although positive initiatives have been taken, regulatory implementation remains weak and often fails to provide effective protection mechanisms for consumers. The policy implications proposed include strengthening standards for environmental claims, expanding the right to repair across sectors, and increasing sustainability literacy at the consumer level. This article aims to enrich academic discourse and serve as a foundation for consumer-based policy development in support of the circular economy agenda.
Abstract:The objective of this study is to examine the management of water production residues and to analyze their implementation in environmental accounting at PERUMDA Air Minum Mutiara Tirta, Gorontalo City. This study employs…
a qualitative method with a case study approach. The research informants were selected using purposive sampling, consisting of individuals who were considered knowledgeable and directly involved in the issues under investigation, including the Production Coordinator, Maintenance Division, Laboratory Officer of Zone 1, Assistant Manager of Secretariat and Public Relations, and the Accounting and Budgeting Officer. Data were collected through interviews, observations, and documentation by applying data source triangulation to ensure data validity. The results indicate that the management of water production residues has been carried out in accordance with Standard Operating Procedures (SOPs); however, its effectiveness remains limited due to constraints in budget allocation, facilities, and waste treatment technology. In terms of environmental accounting implementation, the recognition, measurement, presentation, and disclosure of environmental costs have not been optimally integrated, as environmental costs are still recorded within general operational budgets without specific classification and detailed reporting. This condition reflects existing challenges in linking waste management practices with environmental accounting records. The main obstacles include limited technological capacity, insufficient human resources with expertise in environmental accounting, and the absence of specific regulations governing environmental cost recording. Therefore, clearer regulatory support, dedicated budget allocation, improved waste treatment technology, and employee training are required to ensure a more effective and sustainable implementation of environmental accounting.
