Abstract

Digital transformation in healthcare supply chain management is increasingly important in addressing operational and distribution efficiency barriers. However, many healthcare institutions have yet to adopt Business Intelligence (BI), causing delays in decision-making, inefficiencies in drug stock management, and waste of resources due to suboptimal distribution. The method used is a bibliometric analysis based on literature observations from major academic databases, with a quantitative approach using VOSviewer to map topic relationships, research trends, and collaboration patterns between researchers. The results of the study confirm that the application of Business Intelligence (BI) in healthcare supply chain management is more dedicated to existing technology-based solutions, such as Artificial Intelligence (AI), Internet of Things (IoT), blockchain, and Big Data, compared to new development methodologies. This study found that although BI can increase efficiency in inventory management by up to 50%, accelerate data-based decision-making by up to 40%, and reduce resource waste by 25%, there are still similarities in policy aspects and obstacles that hinder optimal implementation. In conclusion, the application of BI in the healthcare supply chain must be supported by a structured strategy, including investment in digital infrastructure and workforce training. Further research is recommended to explore policies that can accelerate the implementation of BI in the health sector.

Abstract

Quality has become a research concern in the field of manufacturing or services. Currently, there are several tools available that can be used to improve service quality. Each tool has advantages and disadvantages, so integration between tools is needed to increase the effectiveness and efficiency of improvement efforts. Some tools that can be integrated to evaluate service quality comprehensively are SERVQUAL, KANO, and QFD. This scientific article provides experiential information on applying quality tool integration in the health sector. A hospital was selected as a case study for an example of the application of service quality improvement steps. The trial of SERVQUAL, KANO, and QFD integration in the case study showed that the integration of SERVQUAL and KANO selected 30% of critical service attributes that need improvement. Furthermore, QFD plays a role in executing the improvements effectively and efficiently.

Abstract

The government is responsible for ensuring the right to health, one of its efforts is the Healthy Campus program. This initiative underpins the establishment of the ITS Medical Center at Institut Teknologi Sepuluh Nopember (ITS) to fulfill students' rights to healthcare services. ITS Medical Center aims to become the leading healthcare service provider for the ITS academic community and the public in East Surabaya. However, numerous complaints persist, with 50% related to extended service waiting times. Additionally, ITS Medical Center experienced an 11% increase in visitors in 2023. Consequently, a service quality evaluation was conducted by integrating Service Quality (SERVQUAL) and lean concepts to identify service gaps, eliminate waste, and enhance services. The study revealed negative results across all SERVQUAL attributes. Out of 24 identified wastes, 17 were deemed critical. These critical wastes and their associated attributes were grouped and analyzed for root causes using Fault-Tree Analysis. The prioritized wastes include patients waiting for medication preparation, the reprocessing of old patient medical records, and the excessive accumulation of medical records. Recommendations for improvement prioritize recording dispensed medications in stock cards at the end of the day and developing a system for medical record recapitulation. These improvements are expected to enhance service quality and increase consumer satisfaction at the ITS Medical Center.

Abstract

The growth of the construction industry in Indonesia demands a transformation of the technology-based recruitment system to improve efficiency and transparency. PT. Songgo Jati Baru experienced operational constraints due to the manual recruitment process that was prone to delays and human error. To overcome this, a recruitment application was developed to automate the candidate selection process. The system development was carried out using the Agile method iteratively, with UML modeling and Black Box testing. The implementation results were able to accelerate the selection process, reduce errors, and increase transparency. In addition, the application allows the compilation of a candidate database based on technical competency and work experience, which supports the company's long-term recruitment strategy. This study recommends the adoption of a digital recruitment system as a strategic innovation in improving the quality of human resources in the construction sector, in line with the direction of national digital transformation.

Abstract

In this study, a marketing strategy for Xiaomi mobile phones in Indonesia was designed based on market share analysis using the Markov Chain method and SWOT analysis. The mobile phone market is very competitive, so to maintain and increase market share, it is necessary to understand the dynamics of consumer movement between brands. The Markov Chain method is used to model the possibility of customer movement from one brand to another based on historical market share data of several major brands, including Xiaomi, iPhone, Samsung, Oppo, Asus, and Vivo. After the Markov Chain, it is continued with SWOT Analysis and Marketing Strategy Design. Some strategies that Xiaomi can use include creating a user-friendly Xiaomi image, actively advertising and promoting both electronic and non-electronic media, using public figures as brand ambassadors, creating recycling movements, and creating a campaign. This strategy successfully increased consumers' probability of choosing Xiaomi as their main choice.

Abstract

Tourist villages are villages with distinctive traditions, arts, culture and customs passed down from generation to generation which are used as tourist attractions by local residents. The Central Bira Tourism Village with Lon Malang Beach is included in the advanced tourist village category according to jadesta.kemenparekraf.go.id. Based on the results of observations, the management of the Tourism Village has not thought about plans and strategies regarding further development related to the Tourism Village, it has only focused on improving infrastructure, there has not been a plan for further development of the tourism village which has the potential to create risks, and there is a need for strategies to deal with the emergence of these risks. Risk analysis and risk mitigation to prevent risks and disturbances that are likely to arise in tourism village development activities. Risk analysis and determining risk mitigation strategies using the House of Risk method which consists of two implementation stages. The first stage is to identify the risk event, and the cause of the risk, then an assessment of the severity and occurrence values is carried out, followed by providing a correlation assessment of the relationship between the risk event and the cause of the risk. The results of the correlation assessment obtain an Aggregate Risk Potential value. In the second stage, using the Pareto concept, 15 risk agents were identified based on the results of the top ranking, mitigation strategies were used by the tourism village to overcome risks to tourism management activities.
