Effective communication is essential for teamwork effectiveness in healthcare, particularly in inpatient units where patient care requires coordination among multiple professionals. Internal data from Hospital X showed that more than 50% of medical incidents in the last two years were related to miscommunication among healthcare workers. In addition, the 2024 employee satisfaction survey reported that workplace communication satisfaction was only 62%, below the hospital target of 75%. This study aimed to examine the influence of effective communication on teamwork effectiveness with interprofessional collaboration as an intervening variable at Hospital X.This study used a quantitative cross-sectional design involving 226 healthcare workers, including doctors, nurses, and medical support staff. Data were analyzed using the Three-Box Method and PLS-SEM. The findings revealed that effective communication significantly influenced teamwork effectiveness both directly and indirectly through interprofessional collaboration. Interprofessional collaboration also acted as a significant mediating variable between communication and teamwork effectiveness. These results indicate that communication is a key foundation for strengthening collaboration and improving teamwork in hospitals. Therefore, hospitals should enhance communication training and interprofessional collaboration programs to improve healthcare quality and patient safety

Patient-Centered Care (PCC) is a healthcare approach that places the patient at the center of every interaction and clinical decision-making. However, a preliminary study at Tarumajaya Hospital showed that 58% of healthcare workers had not yet optimally implemented the PCC approach. This study aimed to analyze the influence of self-efficacy and social support on the implementation of Patient-Centered Care, with safety culture as a mediating variable, at Tarumajaya Hospital. The research method used was quantitative analytic with a cross-sectional design. The study sample used a saturated sampling technique of 132 healthcare workers, consisting of doctors, nurses, and medical support staff. Data analysis used Structural Equation Modeling–Partial Least Squares (SEM-PLS). The results showed that self-efficacy and social support had a positive and significant effect on safety culture and PCC implementation. Safety culture also had a positive and significant effect on PCC implementation. Furthermore, safety culture was shown to mediate the influence of self-efficacy and social support on PCC implementation. The coefficient of determination value indicates that the model has strong ability to explain variations in PCC.

The Port Clearance Certificate (PCC / SPB) is a mandatory state document issued by the Harbor Master (Syahbandar) as proof of the ship's seaworthiness and the fulfillment of all administrative obligations before leaving the port. In the clearance process for foreign-flagged vessels, the role of the shipping agent is crucial as the representative of the ship owner to coordinate all required permits and documents with various related government agencies (Harbor Master's Office/KSOP, Customs, Quarantine, and Immigration). PT. Dalian Putra Maritim Belawan Branch utilizes an integrated digital system (Inapornet) to manage ship agency services for both incoming and outgoing vessels. This study aims to comprehensively analyze and describe the role and effectiveness of the ship agent, PT. Dalian Putra Maritim Belawan Branch, in expediting the process of issuing the Port Clearance for foreign ships at the Harbor Master and Port Authority Office (KSOP) in Belawan. This research employs a qualitative-descriptive method supported by: 1) Library Research to collect theoretical data and regulations; and 2) Field Research, which involves direct observation of Standard Operating Procedures (SOPs) and the collection of accurate data within the Belawan Port environment. The research results indicate that the ship agent plays a central and vital role in the entire Port Clearance issuance process. The success of issuing the Port Clearance is heavily dependent on the speed, accuracy, and efficiency of the coordination carried out by the agent, ensuring that the vessel meets all safety, security, and maritime environmental protection requirements before being permitted to sail.

Urban logistics is a significant source of carbon emissions in Indonesia, and effective decarbonization strategies are required. EVs offer a promising solution, but their impact requires quantitative evaluation within the local context. This study analyzes the effect of adopting an electric van fleet on total well-to-wheel carbon emissions within an urban distribution network in Indonesia. This study employs a comparative case study method. A baseline scenario consisting of 25 diesel vans is compared to an intervention scenario where electric vans replace the entire fleet. The emission analysis was conducted using the WtW framework, utilizing specific emission factors for diesel fuel from the IPCC (2006) and the Java-Madura-Bali (JAMALI) grid emission factor from IESR (2023) to ensure contextual relevance. The transition to an electric fleet successfully reduces the total well-to-wheel carbon footprint by 13.63%. This reduction is equivalent to an absolute CO2 emission decrease of nearly 3 tons of CO₂ per month. Nevertheless, indirect emissions from electricity generation still contribute a significant carbon footprint, indicating that the national energy mix is highly dependent on the environmental benefits of EVs. This study concludes that fleet electrification is a viable and effective decarbonization strategy for Indonesia’s logistics sector, even with the current state of the electricity grid. However, fleet decarbonization efforts must run in parallel with policies for a national transition toward renewable energy to maximize the emission reduction potential of electric mobility. Future research should include the total cost of ownership (TCO) and life cycle assessment (LCA) for a more holistic evaluation.

This paper explores how climate change has contributed to the armed conflict in Darfur, Sudan, by emphasizing the human security perspective. Prolonged drought, desertification, and resource scarcity have intensified tensions between farming and pastoralist communities. Using a case study method and the Human Security framework, this study finds that ecological stress acts as a threat multiplier in conflict-prone areas. Data from IPCC, SIPRI, and UNHCR reports highlight how environmental degradation worsens structural vulnerabilities and fuels horizontal violence. The analysis shows that climate change is not only an environmental issue but also a serious security concern in fragile states. The failure of state institutions to equitably manage natural resources exacerbates the crisis. Therefore, a long-term, multi-sectoral policy response is urgently needed. Integrating climate resilience into international security strategies is essential to protect basic human rights.

The impact of carbon emissions as a major cause of climate change has raised concerns and become a challenge for the international community. To reduce emissions, it is necessary to study the carbon footprint of activities in Al-Amin. The planning of Al Amin Living lab and Industrial Park along with the administration in which various activities produce carbon emissions these activities need to be calculated to find out how much the activity contributes to the emissions produced so that negative impacts on the environment can be minimized. Opportunities for PSE-GR Development Areas with the concept of Eco-Tech-Edu Tourism which has an understanding of Circular Economy Education (CED) is still very minimal in North Sumatra, PSE-GR can be a pioneer in spreading this understanding of CED where the integration of economic and educational activities occurs which at the same time helps maintain the preservation of nature. Encouraged by the development of the Independent Learning Curriculum (ILC), it is hoped that PSE-GR can become a place for research, service, and practicum of the UNPAB academic community that increases awareness of the need for nature conservation. Because Green Technology from across fields of science is still very minimally discussed and is still often partially researched, UNPAB can be an example of the integration of fields of science that become practical, dynamic, educational, and economic value innovations. The existence of 20 ha of land owned by the Prof. DR H Kadirun Yahya Foundation, it is hoped that UNPAB can develop a Living lab ecosystem at least on 10 ha of land. PSE-GR is not expected to be as exclusive as tourist areas in general, with the concept of CED, PSE-GR will not only help become an income generator & source of educational land for the academic community but also help the welfare of the village and the surrounding community. Carbon footprint studies are carried out in 3 scopes according to The Greenhouse Gas Protocol (GHG Protocol), namely emissions from sources owned or directly controlled by the faculty, indirect emissions from electricity consumption, and other indirect emissions (WRI and WBSCD, 2004). Carbon footprint emissions from all three scopes are calculated based on methods from the International Panel on Climate Change (IPCC) for the national greenhouse gas (GHG) inventory.

Patient-focused services or commonly called Patient Centered Care (PCC) have become the main focus in providing health care today. The PCC concept was first introduced by Picker in 1988 through the Picker Institute Europe in England. Regional General Hospital (RSUD) Dr. M Haulussy Ambon is a hospital that has been accredited and is required to be able to implement PCC in its services. Purpose this study was to determine the ability of nurses to apply PCC at RSUD dr. M. Haulussy Ambon. The research design used is descriptive quantitative using observational. The population in this study were nurses at RSUD Dr. M Haulussy Ambon as many as 302 nurses. The number of samples is 113 respondents. data collection techniques using a questionnaire. Results: Most of the nurses' ability to apply PCC showed good results but there were still a number of PCC dimensions that had sufficient results. The PCC dimensions that get good results are respecting patient choices and assessments, physical comfort, information and education, service coordination, and involving family and friends. It can be concluded that most nurses are capable of implementing PCC.
