Purpose: The cardiovascular system is a vital system responsible for the distribution of oxygen and nutrients throughout the body. The complexity of interactions between the heart and blood vessels often presents challenges in monitoring and analyzing health conditions. The research proposes the development of a Human Digital Twin (HDT) for the cardiovascular system through application of two different modelling approaches geometric modeling and physic-based modeling. Through this model physical conditions can be represented and real time data integrated to offer insights into the dynamics of the cardiovascular system.
Methods: This model development is based on two major components: a geometric modeling and a physic-based modeling. The geometric model is done in 3D to show the structure of the heart in detail, while the physical-based model is tabulated with different measurable physical parameters in the cardiovascular system, such as blood pressure and flow rate. This information is integrated into the Five Dimension Digital Twin model, including physical, virtual, data, connection, and service dimensions for the accurate simulation of cardiovascular conditions.
Result: Results confirm that the Five-Dimensional Digital Twin (DT) could give further development to how the dynamics of the cardiovascular system behave, possibly in real-time updates on conditions and a supply of data that is far more detailed in view of analyzing risk and further representation of specific cardiovascular disorders while providing personalized medical support.
Novelty: The Five-Dimensional Human Digital Twin Model (HDTM) developed in this research introduces novel innovations in the monitoring and simulation of the cardiovascular system through the application of geometric and physic-based modeling techniques. This approach offers a higher level of detail, compared to previous models, and added value for the advancement of health technology by integrating real time data into the simulations. This model serves not only as an advanced analytical tool but also as a reference for further research on DT technology in the medical field.

Coordination is the unification of perceptions between different parts within the organization so that they work together in order to contribute to the organization to achieve its goals. The purpose of this study was to analyze and explain the implementation of the coordination of the Pekanbaru City Health Service and the Pekanbaru City Regional Financial and Asset Management Agency in deleting assets for special operational service vehicles (ambulance). The theory used for the measurement in this study uses a theory that includes communication, awareness of the importance of coordination, participant competency, agreement, commitment and coordination incentives, and planning continuity. The type used in this research is descriptive research with qualitative methods. The results of this study indicate that coordination between the two agencies has been carried out, but there are still things that have not run optimally, namely coordination of preparing vehicle documents both before they were deleted and after they were deleted, more intensive communication, employee capabilities, and maximum participation. The two agencies must play a more optimal role by increasing their performance in order to coordinate so that what has been determined will be optimally achieved.Koordinasi merupakan penyatuan persepsi antara bagian-bagian yang dberbeda didalam organisasi agar saling bekerjasama dalam rangka memberikan sumbangsih kepada organisasi untuk mencapai tujuan. Tujuan penelitian ini adalah untuk menganalisis dan menjelaskan pelaksanaan koordinasi Dinas Kesehatan Kota Pekanbaru dan Badan Pengelolaan Keuangan dan Aset Daerah Kota Pekanbaru dalam penghapusan asset Kendaraan Dinas Operasional Khusus (ambulance). Teori yang digunakan untuk pengekuruan dalam penelitian ini menggunakan teori yang meliputi komunikasi, kesadaran pentingnya koordinasi, kompetensi partisipan, kesepakatan, komitmen dan insentif koordinasi serta kontinuitas perencanaan. Tipe yang digunakan dalam penelitian ini adalah penelitian deskriptif dengan metode kualitatif. Adapun hasil dari penelitian ini bahwa koordinasi antara kedua intansi telah dilakukan, namun masih terdapat hal-hal yang belum berjalan maksimal dinataranya adalah koordinasi mempersiapakan surat-surat kendaraan baik sebelum dihapus maupun telah dihaspus, komunikasi yang lebih instensif, kemapuan pegawai, partisipasi secara maksimal. Kedua intansi harus berperan lebih maksimal dengan cara meningkatkan kinerjanya dalam rangka melakukan koordinasi agar apa yang telah ditentukan akan tercapai secara maksimal.
