Abstract

Proses pembuatan _small aluminium boat_ telah lama dikenal dalam bisnis rancang bangun kapal. Aluminium dianggap sangat berguna karena memiliki sifat ringan, kuat, serta tahan terhadap lingkungan. Korosi akibat air laut atau air tawar memiliki pengaruh yang cukup kecil terhadap badan kapal. Paduan aluminium cenderung mempunyai daktilitas yang rendah, oleh karena itu bentuk badan kapal yang dapat dibuat sangat terbatas. Jika keindahan bentuk kapal menjadi prioritas utama, maka paduan aluminium menjadi pilihan yang kurang menguntungkan.

Dalam proses pembangunan _Small Aluminium Boat_ melibatkan berbagai macam aktivitas, mulai dari tahap persiapan, fabrikasi, _assembly_, _outfitting_, pengecatan, sampai tahap penggabungan, sehingga di lapangan masih banyak terdapat cacat-cacat yang timbul. Dengan pendekatan analisis risiko serta analisis akar penyebab, dapat mengurangi terjadinya cacat yang akan timbul. Metodologi FMEA (_Failure Mode and Effect Analysis_) merupakan suatu pendekatan sistematis untuk menganalisis dan menilai potensi kegagalan dan penyebab kegagalan serta mencegah hal tersebut terjadi. Penelitian dilakukan pada proses pembangunan kapal aluminium dengan mencari nilai ketegasan, kekerapan, dan pengesanan. Hasil dari ketiga nilai tersebut menghasilkan _Risk Priority Number_ (RPN) untuk setiap potensi kegagalan yang timbul.

Setelah nilai RPN diketahui, maka harus segera direkomendasikan tindakan perbaikan yang mencakup penanggung jawab dan batas waktu, serta mencatat setiap tindakan perbaikan yang telah dilakukan. Langkah terakhir yang dilakukan adalah perhitungan ulang nilai RPN.

The manufacture of boats from aluminum has been known for a long time in the boat-building industry. Aluminum is considered a useful material for watercraft because it is lightweight, strong, and weather-resistant. Neither saltwater nor freshwater has a significant impact on the durability of aluminum. On the other hand, aluminum alloys tend to have limited ductility, making them difficult to form and therefore less desirable as a building material when formability is a priority.

There are many activities involved in the construction of small aluminum boats, including preparation, fabrication, assembly, outfitting, painting, and erection. Therefore, defects are often found in each activity. By using a Risk Assessment and Root Cause Analysis approach, potential failure risks can be identified. Failure Mode and Effect Analysis (FMEA), one of the root cause analysis tools, is a systematic engineering approach used to analyze and evaluate the potential failure modes and effects of a product or process. This study focuses on the construction process of a Small Aluminum Boat by determining the Severity, Occurrence, and Detection rankings for each failure mode. The Risk Priority Number (RPN) can then be calculated.

After the RPN value has been determined, corrective action recommendations must be implemented immediately, including identifying the person in charge, setting a target completion date, and recording every corrective action that has been taken. The final step is to recalculate the Risk Priority Number.
