Abstract

Pipe receiving is one of the operational activities with a high potential for occupational hazards because it involves unloading, lifting, transporting, and storing pipes using lifting equipment, as well as direct interaction between workers and heavy materials. Unsystematic hazard identification and control can increase the risk of workplace accidents, material damage, and operational disruption. This study aims to identify potential hazards at each stage of the pipe receiving process using the Job Safety Analysis (JSA) method and to evaluate its conformity with the ISO 45001:2018 approach at PT. XYZ. A descriptive method with a qualitative approach was employed. Data were collected through direct observation, interviews with workers and HSSE personnel, and documentation studies. The findings indicate that the pipe receiving process consists of ten work stages with various hazards, including being struck by materials, caught between objects, slipping, falling loads, and collisions with lifting equipment. Recommended control measures include toolbox meetings, equipment inspection, safe work procedures, barricade installation, improved compliance with Personal Protective Equipment (PPE), and regular supervision. The controls applied at PT. XYZ are generally consistent with Clauses 6.1.2, 8.1, and 9.1 of ISO 45001:2018, although continuous improvement in supervision and evaluation is still required.

Abstract

Pompa adalah suatu alat untuk memindahkan cairan bahkan benda padat dari suatu tempat ke tempat lain dengan cara menambahkan energi kepada cairan tersebut. agar dapat melaksanakan tugasnya, pompa perlu di gerakkan oleh motor listrik, mesin diesel atau mesin penggerak lainnya. Karena pompa digerakkan, pompa memperoleh energi dari penggeraknya, kemudian energi tersebut diteruskan atau diberikan oleh pompa terhadap cairan, sehingga dengan pompa cairan dapat dipindahkan dari tempat rendah ke tempat yang lebih tinggi,cairan dapat dipindahkan dari tekanan rendah ke tekanan tinggi,debit cairan dapat diperbesar. Pemindahan cairan melalui saluran dengan menggunakan pompa menjadikan cairan akan mengalir, sehingga kinerja pompa berkaitan dengan aliran cairan. Pada aliran cairan terdapat dua bentuk energi.yang pertama energi potensial yaitu bentuk energi yang ada pada cairan sehubungan dengan letak dari cairan tersebut. Makin tinggi letak cairan dari dasar, makin besar energi potensial cairan itu.demikian pula makin besar tekanan cairan semakin besar pula energi potensial cairan itu,yang kedua energi kinetik yaitu bentuk energi yang ada pada cairan sehubungan dengan kecepatan gerak cairan tersebut. makin besar kecepatan gerak cairan makin besar energi gerak cairan tersebut.
