Analysis of Patient Flows Using Discrete-Event Simulation (Case Study: Emergency Department of Hospital X)
Get PDFThis research is intended to analyze the patient flows through a number of processes in the Emergency Department (ED) using Discrete Event Simulation (DES) approach. In this paper, the time that a patient spends in the ED as well as the total number of patients served by the ED in a day were investigated and compared with the standard of the medical service time set by the hospital. A case study of Hospital X’s ED in Jakarta, Indonesia was modeled using ProModel software. In addition, this research also proposes a number of considerable scenarios for defining the suitable number of beds and nurses. The results signify that the average time spent in the ED and the number of patients served can be optimized by adding 1 nurse and 2 beds. This finding signifies that the DES modeling approach may assist the hospital managers with the decent decision for improving the efficiency of the patient flows in the ED

ANALISIS MANAJEMEN RESIKO APLIKASI MYPERTAMINA DENGAN MENGGUNAKAN ISO 31000
Get PDFDigitalization is one of the major trends changing society and business in the near and long term. Digitalization can impact the entire operating environment and internal functions of a company. To increase value added in retail, PT Pertamina Patra Niaga launched the MyPertamina application. Based on data on the number of application users in the Playstore, mypertamina application users have increased. With this increase, many problems must be faced by the company. Therefore, an analysis of risk management is needed to minimize losses that will occur. ISO 31000 is used as a standard for implementing risk management. ISO is considered to have a framework that is straightforward and easily adaptable to companies. This study aims to identify the risks that will occur in using the MyPertamina application and the highest level of risk that must be watched out for and its countermeasures. The results showed that there were 17 identified risks with 3 high-level risks, 8 moderate-level risks and 5 low-level risks. Proposed improvements in this study are prioritized at high levels of risk
ANALISIS PENGARUH KESELAMATAN, KESEHATAN, DAN LINGKUNGAN KERJA TERHADAP KINERJA KARYAWAN BAGIAN WORKSHOP (STUDI KASUS: PT XYZ)
Get PDFThis research was carried out with the aim of evaluating the impact of the working environment, health and safety at work on the performance of workers in the PT XYZ Workshop division. I thought about using Structural Equation Modeling (SEM) based on Partial Least Squares (PLS), and SMARTPLS software uses Least Squares handling for variation. The analysis results show that occupational safety and health factors have a significant influence on employees’ work performance and motivation, while work environmental factors do not have a significant impact on performance. And employee work motivation. Furthermore, work motivation has no effect on employee performance, so it does not play a mediating role in the relationship between safety, health and the work environment and employee performance
ANALISIS RISIKO DALAM PROSES PENGADAAN JASA DI RU III MENGGUNAKAN PENDEKATAN HOUSE OF RISK (HOR)
Get PDFThis study analyzes risks in the procurement process of services in RU III using the House of Risk (HOR) approach to enhance risk management effectiveness. Risk identification is conducted through observation, interviews, and relevant literature review. The analysis of HOR phase 1 identifies three best risk mitigation strategies: coordination with vendors/FPP before open registration (PA1), clarification of technical and administrative documents (PA2), and maximum negotiation and tender reprocessing if below Pertamina's HPS (PA3). HOR phase 2 involves calculating the Total Effectiveness Value (TEk) and the Efficiency Difficulty Ratio (ETDk) to evaluate the effectiveness and implementation difficulty of the mitigation strategies. This research provides recommendations for implementing the identified mitigation strategies and periodic monitoring to enhance risk control. The findings of this study contribute to the development of service procurement risk management in RU III and serve as a reference for decision-makers in risk mitigation during the service procurement phase
Optimizing Transit Operations and Passenger Experience: A Simulation-based Study of Bus Interarrival and Passenger Load Scenarios at a Major Transfer Point
Get PDFThis study employs simulation-based analysis of passenger flow and bus operations at the Adam Malik transfer point within the TransJakarta BRT system. The findings from the analysis of the current system indicate that the average number of total passenger exits in corridors 13, 13B, 13C, and L13E were 618, 509, 1143, and 790, respectively. Additionally, the average time spent by passengers within the system for each corridor was 4.48 minutes, 6.12 minutes, 5.94 minutes, and 5.46 minutes, respectively. Through the development of 15 scenarios, the study demonstrates the impact of adjusting passenger boarding procedures and reducing interarrival time on waiting times and passenger processing efficiency, particularly during peak hours. The results emphasize the substantial influence of these variables on waiting times, total exits, and system duration for passengers and buses

Get PDFPT. Pelabuhan Indonesia (Pelindo) is a world-class port offering integrated services between Indonesian ports. The establishment of Perind as a result of this integration is a strategic initiative of the government as a shareholder to realize national connectivity and a stronger logistics ecosystem network. This study was conducted with the aim of identifying hazards, assessing risks, and managing port service activities. Use HIRARC (Hazard, Identification, Risk Assessment and Risk Management) and SWOT (Strength, Weakness, Opportunity, and Threat) methods to identify hazards and perform risk assessments. With the use of the HIRARC method, 10 potential risks were found in one green risk assessment indicating that the potential problem was moderate. For inventory warehouse personnel activities, the value is 3, and the warehouse worker or worker unloading value is 3. Mixed strategies can be found in the four quadrants of analysis using SWOT for the following purposes: Improving and improving the quality of the company
Location Design of GIS-Based Temporary Evacuation Sites (TES) by Considering the COVID-19 Pandemic Situation: A Case Study in Padang City)
Get PDFPadang City is an area that is predicted to occur in the Mentawai Megathrust disaster. In dealing with these potential disasters, proper planning is needed to reduce the impact of disasters. The exact location of the Temporary Evacuation Sites (TES) will affect the safety level of the community. However, based on the current situation, the COVID-19 pandemic adds to the complexity of disaster management. Therefore, anticipatory steps are needed to prevent the spread of disease in the environment. This study aims to design a TES location-allocation to deal with the potential Mentawai Megathrust disaster in Padang City by adjust to physical distancing health protocols. Determination of the location-allocation in this study is using Network Analysis extension namely Maximum Capacitated Location Problem (MCLP) in Geographic Information Systems (GIS). In addition, this study uses an evacuation time scenario with an interval of 3-30 minutes consisting of two different scenarios involving the use of community response times to disasters. The location-allocation results consist of four results based on the scenario of evacuation time and the addition of Proposed TES. Based on the location-allocation results, with the addition of Proposed TES, the maximum number of people that can be accommodated is only around 34-39 percent in both evacuation scenarios. This shows that there is a need for further design related to both Existing TES and Proposed TES so that the percentage of the number of people who can be accommodated can increase
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
