Fault tree analysis adalah suatu penilaian risiko yang mampu mengidentifikasi potensi bahaya secara spesifik, fokus, rinci pada satu kejadian yang tidak diinginkan, dan mengetahui penyebab kejadian tersebut beserta angka probabilitasnya. Tercatat mulai tanggal 1 Januari – 30 April 2014 terjadi kebakaran sebanyak 10 kali di divisi spinning PT. Apac Inti Corpora dengan kasus tertinggi di unit spinning V (50% kejadian).Tujuan penelitian ini adalah mengetahui faktor penyebab kebakaran, mengembangkan penilaian risiko, dan mengetahui gambaran umum sistem manajemen penanggulangan kebakaran di unit spinning V PT. AIC. Desain penelitian ini adalah kualitatif eksplanatoris. Hasil pengembangan bagan fault tree analysis didapatkan 41 basic event, 24 intermediate event, 1 conditioning event, dan 1 undeveloped event yang secara matematis melalui persamaan aljabar boolean akan menghasilkan 35 single minimum cut sets dan 5 double component cut sets, dengan perhitungan angka probabilitas sebesar 0,3552. Hasil kesesuaian sistem manajemen penanggulangan kebakaran didapatkan 76 poin dari 81 poin standar regulasi yang berlaku di Indonesia. Simpulan penelitian ini adalah kemungkinan terjadinya kebakaran di spinning V sebesar 35,52%. Saran dari penelitian ini adalah dilakukannya evaluasi terhadap kegagalan deteksi dini dan kegagalan teknis. Fault tree analysis has advantages in identifying potential hazards in specifics, focus, detail on a potential undesirable event that called top event, and was able to find out the causes with the value of probability. Recorded at January 1th – April 30th, 2014, there had been 10 cases of fires in the spinning PT. Apac Inti Corpora with the highest cases at spinning V (50% event). The purpose of this research was find out the cause of fires, develop a risk assessment, and learn an overview of fires countermeasures management system in spinning V. This research was a qualitative – explanatory design. Result of development fault tree analysis brings about 41 basic event, 24 intermediate event, 1 conditioning event, dan 1 undeveloped event  by boolean algebra, mathematically generates 35 single minimum cut sets and 5 double component cut sets, with the value of probability is 0,3552. Whereas the countermeasure of fire management system conformity obtained 76 points is according from 81 points of regulatory standards in Indonesia. Summary, spinning unit V had the possibility of going fires is 35,52%. Advice, conducted evaluation of failure from early detection and technical failures in the production process.

Cut Set

In case of fault tree analysis of large complex system, the probability of bottom event in dynamic fault tree is uncertain in some cases. To address the problem, the paper presented a dynamic fault tree analysis method based on fuzzy set computation. The method separates logic attributes and timing attributes of dynamic logic gates. It can convert dynamic fault tree into static fault tree not considering timing constraints and obtain minimum cut set of static fuzzy fault tree with set operations, then the concept of minimum cut set is extended to dynamical minimum cut sequence. Thus, the dynamic fault tree was analyzed in both qualitative and quantitative aspects, which solve the problem that it is difficult to assign value of event probability in previously process.

Offshore Operations

Safety and dependability are major design objectives for offshore operations such as the construction of wind farms or oil and gas exploration. Today processes and related risks are typically described informally and process specification are neither reusable nor suitable for risk assessment. Here, we propose to use a specification language for processes. We integrate this specification language in a generic modeling approach in combination with an analysis tool and a tool to construct health, safety and environment (HSE) plans — a mandatory document for granting a construction/operation permit. Specifically, for each planned scenario a process is modeled, describing the detailed operation of the involved actors as well as the interaction with resources and environmental conditions. We enrich this process model with hazardous events which is facilitated by integration with an offshore operation generic hazard list, thereby giving access to expert knowledge for the specific situation to be planned. This in turn allows us to perform an automatic quantitative risk assessment using fault tree analysis. We exemplify our approach on a standard offshore operation of personnel transfer from an offshore building to another naval unit by modeling, annotating with hazards, performing the fault-tree analysis, and finally generating HSE plans.

Accuracy Level

<p><em>Building a construction project is an activity which contains many dangerous elements.  It causes the construction industries have bad record in the terms of occupational safety.  Therefore, occupational safety is an aspect that must be improved any time because it is a very complex problem which covers issues in the terms of humanity, legal aspect, accountability and the image of the organization itself.  This study aims to (1) Determine the accuracy level of the Occupational Safety Management System Application in the Service Building (physical) Construction Project in Tidar Regional Hospital (RSUD) Magelang, (2) Identify and analyze the potential risks of work accident by using Fault Tree Analysis (FTA) method and planning mitigation to reduce the scope of construction in progress. This study is a quantitative analysis where the research is conducted by collecting the primary data through interview and observation, meanwhile the secondary data is in the form of data from the project itself. FTA is used to investigate the potential of workplace accidents by analyzing the direct causes to the basic causes of the accident itself.  The results of the study show that (1) The accuracy level of the application of Occupational Safety Management System which has been applied has an assessment rate of 97.29% and it is included in the level of satisfactory assessment.  (2)  The results of the analysis using FTA obtained several incidents that potentially can cause workplace accidents, incidents such as the workers who do not wear personal protective equipment, workers who act carelessly, and the lack of work experience are the frequent cases in the basic FTA incidents. </em></p>
