Abstract

As the frequency, severity, and costs of safety risks continue to become a challenge for mining industry, the company understood that the existing safety analytic does not provide adequate information, as it has been relying predominantly on collecting and evaluating aggregated data of lagging indicators about past accidents. This method has been negatively driving the organization to carry out repetitive cycle of accident analysis and problem solving, and therefore, undertaking reactive responses. This paper investigated how statistical process control, in particular control charts, can be applied to hazards data, as the leading indicator of accidents, to detect statistically trends in safety process and safety behavior, aiming to control the safety process in real-time manner before the occurrence of accidents. The result showed that the latest iteration of control limits development in Phase 3 is suitable as the control chart for safety process in one of case study mine operation site. Furthermore, the implementation of control charts to hazards data not only it helps the organization to transition its safety analytic to leading indicator analysis, it enables the organization to control safety process in real-time practice and to carry out timely safety intervention long before the potential occurrence of severe accidents, in which within this case, the first early warning signal was triggered 49 days before the occurrence of the fatality accident.

Abstract

The purpose of this research is to analyze the performance of the queuing system and parking needs at Bandar Lampung Mall Transmart Carefour. With various kinds of facilities available at Transmart Carrefour Mall, it can affect the number of visitors or the number of customers who come. The survey was conducted for 1 day and the observations were carried out for 10 hours at 10:00 to 20:00 WIB.This research was conducted in the parking area of the Transmart Carefour Mall and this survey included recording the number of vehicles, recording the number of vehicle police and the service time of vehicles entering and leaving the study site. The results of research on parking needs obtained the highest accumulation occurred on Saturday at 15.01-15.30 WIB namely 162 vehicles. The unit of car parking space (SRP) currently is 300 slots. With the accumulation and number of parking spaces, the available parking lots are not enough in the standard value but what happens in the field, the SRP can still accommodate customers who come. The highest average arrival rate at the entrance is 16 vehicles/hour with a service time of 15.6 seconds/vehicle. Thus there is still a lot of freedom in the parking gate, with the gate idle probability value of 0.366, so the parking gate is not too busy. Keywords: Parking Accumulation, Parking Space Unit, Arrival Rate, Service Time
