Abstract

Worker certification is an important aspect in supporting company operations, especially in the oil and gas industry which has high work risks and requires workers with competencies that meet established standards. PT Pertamina Hulu Indonesia Regional 3 Zone 9 needs to ensure that worker certification validity periods are properly monitored so that recertification can be planned on time. The problem identified in this study is that certification monitoring is still carried out manually using Microsoft Excel, which requires data to be checked one by one and increases the risk of overlooking certifications that are approaching their expiration dates. This study aims to apply the Plan-Do-Check-Act (PDCA) method to improve the monitoring system and to design an interactive dashboard to support the control of worker certification data. The data used in this study consisted of historical training and certification records from 2023 to 2025. Data processing was conducted through cleaning, standardization, Master Data preparation, and the addition of supporting columns such as expired date, total day, month, remaining days, status reminder, priority, cost cluster, and training category. The processed data were then developed into dashboards using Microsoft Excel and Power BI. The results show that the designed dashboard can present certification information in a more concise, structured, and understandable format. Microsoft Excel was considered more suitable for daily operational monitoring because it is easy for the Human Capital Business Partner (HCBP) function to use, while Power BI was more effective for reporting needs due to its stronger visual display. The application of PDCA and the design of an interactive dashboard can support a more directed worker certification monitoring process. Keywords: PDCA, dashboard, monitoring, certification, Power BI

Abstract

TThe process of oil palm plantation maintenance at PT Perkebunan Nusantara IV Regional V that is not running optimally can cause various activities that do not add value (waste), such as waiting time, unnecessary movements, excess processes, and inefficient use of resources. The process of oil palm plantation maintenance includes various activities such as disk and market pickers, wire rope pickers, pest control, castration, preliminary shoots, stock inventory, construction of garden facilities, fertilization, and insertion. The complexity of these activities has the potential to waste time, so exploration was carried out through field observations, interviews, documentation, and literature studies to classify activities into Value Added (VA) and Non Value Added (NVA). The current state results show a Value Added Time (VAT) of 8,636 hours and a Non Value Added Time (NVAT) of 2,344 hours, which is dominated by wasteful waiting, transportation, and unnecessary movements. Based on this analysis, a future state was compiled with recommendations for improvements in the form of adding a tool warehouse and water tank in the garden area, adding workers, and improving coordination and process flow. This proposal is estimated to reduce NVAT to 1,640 hours and increase the efficiency of the oil palm maintenance process. With a Process Cycle Efficiency (PCE) value of 78.65%, dominated by wasteful waiting, transportation, and unnecessary movements, a future state was developed with recommendations for improvements such as the addition of a tool warehouse and water tank in the plantation area, additional manpower, and improved coordination and process flow. This proposal is estimated to reduce NVAT to 1,640 hours and increase the PCE value to 81.23%, thereby increasing the efficiency of the oil palm maintenance process by 2.58%

Abstract

The emergence of Balikpapan City Trans (BaCitra) as a new mode of transportation has caused concern among public transportation (Public Transportation) drivers due to a decline in passenger numbers. This study aims to analyze the impact of BaCitra's presence on public transportation usage using a Dynamic System approach. The analysis was conducted to identify factors influencing mode choice, develop a Causal Loop Diagram (CLD) and Stock and Flow Diagram (SFD), and formulate improvement strategies that could create intermodal balance. Based on existing modeling results, within five years the number of Public Transportation passengers decreased from 9,516 to 4,228 passengers, while the number of BaCitra users increased from 8,125 to 21,447 passengers. This imbalance led to the formulation of seven improvement scenarios. Scenario 7, which is a combination of increasing BaCitra fares and maximizing Public Transportation safety and comfort (value 1), is considered the most effective scenario. The implementation of this scenario resulted in 15,523 Public Transportation passengers and 14,112 BaCitra passengers. The results of the study show that this combined strategy is able to create a balance in the choice of transportation modes by the community, so that Public Transportation can continue to operate without sacrificing the quality of BaCitra services.
