Abstract

The rapid advancement of health information technology has encouraged hospitals to provide fast, accurate, and integrated healthcare services that support physicians' clinical decision-making. At TK III Ciremai Hospital, access to patient information and electronic medical records is currently limited to desktop- and web-based Hospital Information Systems (HIS), restricting physicians' mobility and reducing the efficiency of healthcare service delivery. This study aims to design a mobile-based Physician Information System integrated with the Hospital Information System (HIS) to enable physicians to securely access clinical information through Android smartphones. A qualitative research approach was employed using observation, semi-structured interviews, and document analysis to identify system requirements. The system was designed using the Waterfall software development model, while Java, MySQL, RESTful APIs with JSON data exchange, and Unified Modeling Language (UML), including Use Case Diagrams and Entity Relationship Diagrams (ERD), were utilized to develop the system architecture and database design. The scope of this study is limited to the system design phase and does not include system implementation or performance evaluation. The study produced a prototype design of a mobile-based Physician Information System that provides access to patient demographic information, electronic medical records, laboratory and diagnostic examination results, and physicians' practice schedules while emphasizing data security and usability. The proposed design is expected to serve as a reference for developing integrated mobile physician information systems that improve healthcare service efficiency, enhance physicians' mobility, and support evidence-based clinical decision-making in hospitals.

Abstract

Ship repair projects are characterized by complex activities, interdependent work processes, and strict completion schedules. Delays in ship repair projects may result in increased operational costs, additional labor costs, and disruptions to the vessel's operational schedule. Therefore, an appropriate scheduling method is required to identify critical activities and determine efficient acceleration alternatives from both time and cost perspectives. This study aims to optimize the time and cost of a Work Barge repair project at PT Pasifik Karyasindo Perkasa by applying the Critical Path Method (CPM), Program Evaluation and Review Technique (PERT), and the crashing method using the Time-Cost Trade-Off approach. The study focuses on accelerating the repair project through additional working hours or overtime without causing disproportionate increases in the project budget. CPM is applied to determine the project network, project duration, and critical activities, while PERT is used to estimate the expected project duration based on optimistic, most likely, and pessimistic time estimates and to determine the probability of project completion. Furthermore, crashing analysis is conducted by comparing normal and crash durations as well as normal and additional overtime costs. The efficiency of each acceleration alternative is determined based on the additional cost required for each unit of time reduction using the cost slope approach. The final analysis is intended to identify the optimal combination of project duration and cost, enabling project acceleration while maintaining cost efficiency and avoiding excessive budget increases.
