In view of the significant failure modes of formwork-supporting system and reinforced- concrete member, the reliability analysis model of time-dependent system affected by human errors during the construction of typical multistory reinforced-concrete buildings was developed. Human Reliability Analysis (HRA) method was applied to simulate the error rates and error magnitudes of the reinforced-concrete members and the formwork-supporting system, and human reliability models were developed, two cases for error-free case and error-included case were considered. Furthermore the check emphasis of formwork-supporting system was pointed during multistory building construction.

This study conducts a practical application of shipboard operation human reliability analysis (SOHRA) to a crankshaft overhauling operation of a general cargo ship at dry-docking period. The SOHRA approach includes error producing condition (EPC) and general task type (GTT) parameters to consistently calculate the human error probability (HEP) values of operation steps. In this case, a comprehensive overhauling of main engine was planned at shipyard since the ship has experienced a catastrophic failure. An onboard survey to ship engine room is conducted to monitor the operational conditions. The targeted operation, involves disassembly, maintenance, and reassembly stages, is monitored based on 39 sub-tasks. According to the initial findings, immediate recovery actions are suggested to eliminate critical safety issues in a timely manner. Moreover, an extended discussion through long-term safety recommendations are also provided. The results revealed from case study illustrates that HEP values in maintenance operations are sensitive to ship operating conditions. The proposed approach is found very useful by company executives to support ship technical superintendents in critical operation monitoring. The further study is considered to develop mobile application of SOHRA specific to maintenance operations onboard ships.

Fuzzy Logic Approach

Human error is regarded as a critical factor in catastrophic accidents such as disasters at nuclear power plants, air plane crashes, or derailed trains. Several taxonomies for human errors and methodologies for human reliability analysis (HRA) have been proposed in the literature. Generally, human errors have been modeled on the basis of probabilistic concepts with or without the consideration of cognitive aspects of human behaviors. Modeling of human errors through probabilistic approaches has shown a limitation on quantification of qualitative aspects of human errors and complexity of attributes from circumstances involved. The purpose of this paper is to investigate the methodologies for human reliability analysis and introduce a fuzzy logic approach to the evaluation of human interacting system's reliability. Fuzzy approach could be used to estimate human error effects under ambiguous interacting environments and assist in the design of error free work environments.

Task Level

Kesalahan manusia (human error) memiliki keterkaitan dengan tujuan dari analisis keandalan manusia (Human Reliability Analysis). Kecelakaan kerja pada PG Rejo Agung Baru Madiun sebagian besar disebabkan oleh banyak faktor salah satunya ialah kelalaian manusia (human error). SHERPA merupakan salah satu metode untuk menganalisa terjadinya human error dengan menggunakan input hirarki task level dasar. Metode HEART adalah teknik yang digunakan dalam bidang penilaian keandalan manusia, untuk tujuan mengevaluasi kemungkinan kesalahan manusia terjadi diseluruh penyelesaian tugas tertentu. Fungsi utama proses perhitungan dengan metode HEART adalah untuk mengelompokkan task kedalam kategori generalnya dan nilai level nominalnya untuk human unreliability sesuai dengan tabel HEART Generic Task. Hasil penelitian menunjukkan bahwa hasil rekapitulasi nilai HEP untuk semua task yang menyebabkan error yaitu sebesar 0,2718 hasil ini menunjukkan bahwa probabilitas error yang dilakukan operator sebesar 27,18% dan terdapat 2 nilai HEP yang terbesar yaitu pada task 2.2 memanaskan nira hingga suhu tertentu dengan nilai HEP sebesar 0,952557 dan pada task 6.3 pengukuran gas menggunakan parameter PH dengan nilai HEP sebesar 0,849728.

Abstrak, Daftar kasus kecelakaan kerja di galagan kapal yang terjadi selama 8 tahun terakhir dengan jumlah kasus tertinggi pada proses pekerjaan grinding dan welding. Kasus kecelakaan kerja tersebut disebabkan oleh kesalahan manusia atau human error. Pada penelitian ini menggunakan pendekatan Cogitive Reliability and Error Analysis Method (CREAM) untuk memprediksi dan mengurangi terjadinya human error. Pada metode ini dilakukan dengan dua cara yaitu basic method yang berfungsi untuk hanya mendapatkan nilai probabilitas kegagalan secara umum, sedangkan extend method berfungsi untuk mendapatkan nilai probabilitas kegagalan kognitif pada setiap task. Hasil penelitian menunjukkan bahwa faktor yang menurunkan keandalan operator dan mempengaruhi timbulnya human error pada operator grinding dan welding adalah faktor kondisi pekerjaan dan waktu dalam hari saat pekerjaan berlangsung. Nilai probabilitas error tertinggi pada proses pekerjaan grinding dan welding terdapat pada aspek kognitif interpretation, dengan masing-masing nilai CFP pada proses grinding yaitu sebesar 0,024 dan pada proses welding 0,006. Usulan perbaikan untuk mengurangi probabilitas human error pada proses grinding dan welding adalah pada kondisi pekerjaan dengan membutuhkan penerangan yang cukup saat bekerja didalam kapal, membutuhkan sirkulasi udara yang baik saat bekerja didalam kapal, dan membutuhkan peningkatan pengawasan kepada operator agar operator dapat bekerja dengan aman dan disiplin dalam bekerja. Serta membutuhkan pengoptimalan manajemen waktu dalam bekerja, agar operator dapat bekerja dengan baik dan memiliki waktu istirahat yang cukup.   Kata kunci : Human Error, Cogitive Reliability and Error Analysis Method (CREAM), Human Realiability Analysis (HRA).

Human Error Probability

Reliability is always one of the most focal points for the power system researchers. With the improvement of equipment reliability, human error has become a great threat to the power system security. But the human reliability analysis in power system does not get as much attention as it perhaps deserve. As a representative HRA method, the Cognitive Reliability and Error Analysis Method (CREAM) is cited in this paper. And it is applied to evaluate the human error probability of a simple switching operation case. This practice is a beneficial attempt to introduce HRA method into the power system reliability research and lay a foundation for the further explorations.
