Abstract. Indonesia has one of the highest number of fatalities caused by traffic accident. It is become main concern since last decades. Approximately of 10% fatalities is caused by tank truck accident, it recorded by PT. Pertamina Persero, Indonesia in 2015 that 17% and 20% tank truck accident is caused by over speed and fatigue, respectively. Therefore, over speed has become main factor the occurrence of tank truck accident. Main objective of this research is to install speed limiter on the tank truck in order to improve safety engineering system, decrease accident and to maintain engine performance. This research is conducted in Indonesia especially in Java-Bali route travel. Speed limiter is installed to the tank truck engine which completed by fuel cut-off solenoid to reduce the speed automatically when it exceeding the maximum speed that has been determined. From the result shows that top speed which performed by driver up to 133 km/h when tank truck uninstalled by speed limiter. Meanwhile, when speed limiter is installed to the tank truck, top speed locked at 70 km/h even though the driver want to speed up. It means that fuel cutoff system is very effective to lock the speed at 70 km/h and it shown the improvement up to 65%. The monitoring activities observed that the decreasing number of fatalities caused by tank truck accident become 7% as compared to last year of 17%. It can be found that the speed limiter coupled by speed recorder was very efficient to improve safety engineering system of the tank truck.
Fishbone analysis process is a conceptual stage in an engineering role and product design. It's a systematic method to analysis a failure system that was longer used in electronic industry application but not limit to use in oil and gas industry. In risk management concept that a failure as a risk shall prevent and identify in beginning process that may require to minimize them to happen in product and application in oil field equipment. The main interest of this paper is to propose for the potential of fishbone model can be insert and enclose onto risk management system and then implement in an oil field development project in oil and gas industry. This paper is provided a base on research and experiences into risk management and learned from the practical team and their opinion in the industry which matched by an application in oil field development equipment such as actuators, valves and Christmas tree that follow to an industry standard such as API 6A guidelines. A framework of implementation phase for risk management fishbone in an oil field development project in the industry was reviewed and added value by improving an effective communication and skills of the project and engineering team to the stakeholder and organization. The framework that added a Fishbone analysis method in engineering role may become a standard model and may work as a reference for academic and practitioners to help evaluate which risk management need to emphasize in order to maximize the organization in industry outcome from each stage of the model. The framework model may also use for reference of developing the oil field development project with a simple process and can be developed with the same concept for the next wide development project in industry.
Abstract. High pollutant level contributed by mobile sources/land transportation that become main problems for the human health. Improving exhaust emission system by improving catalytic converter properties is one of the most effective way to produce healthy air in our environment. It is conducted by two methods i.e. ultrasonic during electroplating (UBDEL) and electroplating process (EL) which are not fully investigated yet as catalytic converter coating process. UBDEL is conducted using sulphamate types electrolyte solution,
