ABSTRAK Pemodelan merupakan salah satu cara yang digunakan untuk melakukan suatu analisis risiko untuk mengetahui gambaran dan tingkat risiko terhadap potensi kegagalan yang disebabkan oleh adanya beberapa faktor dan dampak yang ditimbulkan akibat adanya kegagalan suatu sistem. Dalam melakukan analisis risiko pada sistem perpipaan yang digunakan untuk menstransmisikan natural gas di PT. XYZ dari suatu tempat ke tempat yang lain digunakan pemodelan dari W. Kent Muhlbauer, dimana model ini secara langsung dapat membantu dalam proses pengolahan data-data untuk menentukan gambaran serta besaran risiko pada suatu sistem perpipaan transmisi. Hasil dari olahan data ini dapat digunakan untuk melakukan justifikasi, tindakan serta sekala prioritas yang harus dilakukan.
ABSTRACT Modeling is one part of ways to determine and define the risk level of potentially failure caused by several factors and impact result due to system failures. On performing of pipeline safety risk analysis where pipeline is used to transport natural gas by PT. XYZ from one place to other place with using W. Kent Muhlbauer’s model. This model will use to calculate and to define the risk level from gathered data that collected from PT. XYZ. The risk analyses results are used to justify the actions are to be taken in accordance with priority level.
Based on the literature review, there is a relationship between work distress and safety climate, which affects to work accidents. This study aims to determine the relationship of the dimensions of work distress to the safety climate. A cross-sectional study was conducted on 152 employees of a gas-fired power plant company at the Prabumulih site, Palembang, and two Batam sites, in the operation and maintenance department who were randomly selected as research respondents. Respondents filled out the Nordic safety climate (NOSACQ-50) and NIOSH Generic Job Stress online questionnaire. Data were analyzed using bivariate correlation statistical tests and linear regression. Company's safety climate showed an average result of 2.73 or at a sufficient level, required improvement in the commitment of the workforce to safety and safety priorities. There were 10.53% of employees who have low levels of distress, 77.63% of employees who have moderate levels of distress, and 11.84% of employees who have high levels of distress. Bivariate analysis showed that the variables of work distress on self-assessment, future work, and social support, showed a significant relationship with safety climate. Multivariate analysis showed that the variables of work distress in conflict and role ambiguity were the most dominant variables related to the safety climate. To improve safety climate, Company should strive to reduce workplace distress through controlling conflict factors and role ambiguity.
ABSTRAK Pengoperasian pipa penyalur gas yang melintasi suatu kawasan tertentu mempunyai potensi risiko (bahaya) dan konsekuensi tertentu berdasarkan kehandalan dari instalasi pipa penyalur tersebut dan produk yang mengalir di dalam pipa tersebut Penelitian ini bertujuan untuk mengkaji risiko pengoperasian pipa penyalur gas sehingga didapatkan gambaran sumber bahaya. jenis bahaya dan risikonya beserta ukuran dan tingkat risiko tersebut yang pada akhimya dapat digunakan sebagai index) sebesar 302,33; nilai chance of survival sebesar 75,58%; chance of Failure 24,42% dan nilai faktor konsekuensi sebesar 8,33. Dengan melihat nilai chance of survival sebesar 75,58o/o., maka secara umum pipa penyalur gas PT. ABC yang dioperasikan pada jalur PT. ABC - PT. XYZ Cilegon Banten masih dalam kriteria aman, namun harus melakukan tindakan prevention dan mitigati secara tepat karena nilai leak impactfactornya sebesar 8,33. Hasil keseluruhan ini menunjukkan bahwa ketiga section yang ada mempunyai nilai yang tidak jauh berbeda, oleh sebab itu semua section yang ada harus mendapatkan perhatian yang sama, yaitu melakukan tindakan prevention dan mitigation secara tepat.
Operation of gas pipelines by PT X, built in 1998 along 14.4 km of which has a danger of gas leaks and fires. Risk analysis is conducted to anticipate the risks that would arise in the gas distribution activities whose results are expected to provide input for the company. This relative risk analysis using semiquantitative methods Risk Rating Index with the approach where the risk of possible dangers (Sum Index) and consequences (Leak Impact Factor). The results showed that the pipelines are in high risk areas (Intolerable) and most of the factors that play a role in contributing to the failure of the operation of the pipeline is the design factor. Keyword : Methods of risk rating index, the relative risk, probability, consequences.
