Abstract

In this final project has been conducted a study on risk analysis on subsea pipeline leakage by using hybrid risk analysis method. The study begins by determining the scope of the analysis using fault tree analysis which can be determined the main event of the leakage failure of subsea pipeline until the basic event. After determining the scope of the analysis then proceeded to calculate the frequency of each event using the quantitative method. In this calculation is known the frequency of basic event through data from scientific paper programming and scientific research and then calculated the frequency result of top event using Boolean Equation until we get the frequency of failure due to leakage pipelines for 0.0141213. After knowing how big the probability of failure, followed by determining how much impact or consequence of the failure. The consequences of failure are determined based on their impact on safety, environment, and business. In the determination of the impact with the qualitative method using questionnaires interviews to some respondents. After obtaining the result of questionnaire interview then calculated the mean of the questionnaire result to determine how big impact of the failure is based on safety, environment, and business. After knowing how big the probability and consequences of the failure, then determine the position of the risk zone on the risk matrix that refers to DNV RP-G101. After knowing the position of the risk zone, it can be determined how to control risk based on cause-effect.

Abstract

Optimizing costs and time and manpower planning are very important in project management. The case study raised in this research is a cooling water pipe fabrication project with a processing time duration of 231 days and a project cost allocation of Rp. 306,545,488,000. The method used to control project delays is earned value analysis, and to optimize the project is done by shortening the project duration and minimizing project cost losses using the crash program method. The results of the earned value analysis stated that the project experienced delays, exceeded budget costs and was subject to project delays penalties, which was 340 days of completion time more than 111 days from the planned time and with a total final project cost of Rp. 331,813,410,524.46 more than Rp. 25,267,922,524.44 of the costs that have been prepared. Then an effort was made to accelerate the duration of the project with three scenario options. From the results of the crash cost calculation, it is found that the final total cost estimate for scenario 1 with 3 hours overtime is Rp. 289,043,553,541. Scenario 2, the estimated total final cost with 4 hours overtime is Rp. 289,051,063,021 and scenario 3 the estimated total final cost with the addition of workers is Rp. 289,310.359,861. So, the scenario that can be used by PT. X in order to minimize losses is to impose 3 hours overtime with an estimated total final cost of Rp. 289,043,553,541.

Abstract

If the social phenomenon is a reflection of nature's thought, our culture and value system, then the multidimensional crisis afflicting our society today requires us to re-examine our educational philosophy and practice at least the past 40 years. We suffer all the bad influences of industrialization as part of the colonial process, precisely because we adopt the most advanced instrument, namely, mass schooling system with an obsession for quality-based standard as the magic spell. In this digital era, the effort of liberating society from the colonial, pioneer of independence as a condition of the proclamation of independence was a reform of the national education system. We should be scheduled deschooling society. This agenda includes the following: the paradigmatic shift from the school system to learning webs based Self Organized Learning Environment (SOLE); mass schooling to individualized, customized learning; of relevance to quality; of technical competence to the independence of the soul or creativity. This reform was way back on the three pillars of education philosophy of Ki Hajar Dewantara: family, community, and College. New demands upon the role of the teacher in the 21st century is changing.

Abstract

Accelerating marginal field development must consider the economic factor. While the structural strength must remain capable and robust when subjected to environmental loads. To meet the desired objective in design phase, optimization is used. With the rapid growth of computing technology, the optimization method is developed as more advanced and reduced iteration time. However, the structural evaluation of jacket structure is a complex problem. The usual process of structure evaluation is through finite element analysis, and it is still time-consuming. Thus, surrogate models can evaluate the structure, lowering computational time. This study optimizes the jacket structure to get an affordable and robust minimal jacket structure. Sizing optimization will be performed on the jacket's leg and bracing thickness. For single-objective optimization, weight structure is considered the objective function, and multi-objective optimization adds production cost as the second objective function. The surrogate model uses the radial basis function to predict the relation between design variables and ultimate limit strength. The functions generated from the surrogate model will act as behaviour constraints in the optimization process. For consideration, X-type and V-type bracing configurations are compared. Different results were obtained from the single objective and multi-objective optimization process.
