Abstract The objective of this paper is to showcase the successful and innovative troubleshooting data analysis techniques in one of the gas compression systems in upstream gas oil separation plants (GOSP-A). The gas compression system using gas compressors, dry gas seal systems and due point controls is used in almost all of upstream operation. These proven data analysis techniques were used to tackle major and chronic issues associated with gas compression system operation that lead to excessive flaring, mechanical seal failures, solidification, hydrate formation and off-specification products. Dry Gas mechanical seals are an important key element in gas compression and its lifetime represents a concern to the operation personnel. Most gas compression systems have a mechanical seal lifetime of 2 years which in some cases limit production, increase the potential of unnecessary flaring and increase OPEX significantly. In addition, solidification due to constant liquid carry over result in a wide range of undesirable results such as blockages that constrain production rates and result in safety concerns. In this paper, comprehensive data analysis of the potential root causes that aggravate undesired premature mechanical seal failure, material solidification, equipment damage and off-specification gas products will be discussed along with solutions to minimize expected impact. For example, improper product specification in some applications have been found to promote seal failures, corrosion, solidification and incur additional flaring which is both costly and environmentally undesirable. In addition, after extensive analysis improper operation practices during compressor startups, steady state operation and gas conditioning have been linked with premature compressor failures, product off spec and safety device failures. The field trial proved the effectiveness of the proposed innovative troubleshooting data analysis techniques in reinstating the gas compression unit in GOSP-A to its recommended design conditions, eliminated compressors and mechanical seal failures and avoided the off-specification products at the lowest operating cost. This innovative technique was based on deep and extensive process data analysis, evaluating operating and design data, reviewing international standards, benchmarking against other facilities, process simulation using Hysys, and finally the actual field trial.

This research is to improve the Character of Child Cooperation through playing blocks aged 4-5 years in the Pusaka Indah Karang Paci Samarinda Kindergarten 2018/2019 Learning Year which is conducted on children aged 4-5 years, totaling 16 children. The research was conducted in 2 cycles, starting with the pre-cycle, the first cycle, the second cycle each carried out as much as 2 meetings with 2 times the learning process. Data analysis techniques use qualitative description analysis, which is a research method that is describing reality or facts in accordance with the data obtained. The results of the research in each cycle can be seen as follows, This can be seen from the results of the pre-cycle average value obtained 24.47%, classified as Not Developing, in the first cycle increased an average of 33.80%, classified as Starting Developing, and at the second cycle increased again with an average of 56.73% classified as Developing as Expected. From the results of this study in each of the above cycles, it can be said that the use of beams can improve the cooperation character of children aged 4-5 years. Based on the results of the study that through playing the beam can improve the collaboration character of children aged 4-5 years in the Karang Paci Samarinda Heritage Park. With the implementation of this class it is hoped that schools, especially teachers, will use this method because the method of playing beams can improve the character of child collaboration.
