Abstract

PT. Perintis Makmur Indonesia (PMKI) is a smelting company that plays an important role in workforce absorption in the Morowali area. In particular, the mechanical department, consisting of 18 employees, requires an upgrade in pipe welding skills using the SMAW welding method. This is due to the fact that the mechanics are currently only capable of performing plate-to-plate welding, whereas they are required to have pipe-to-pipe welding skills to support their work. To enhance its employees' competencies, particularly in pipe welding, PT PMKI collaborated with the Morowali Metal Industry Polytechnic to organize a Shielded Metal Arc Welding (SMAW) training program for its employees. The primary goal of this training was to improve the employees' skills in performing pipe welding safely and efficiently. The training methods included lectures, discussions, and hands-on practice in the workshop, along with evaluations through pre-tests and post-tests. A total of 18 mechanics participated in this five-day training. The materials covered welding safety, SMAW techniques, and defect handling in welding. The results showed a significant increase in participants' understanding and skills. The initial understanding level, as measured by the pre-test, was only 19.8%. After the training, participants' understanding increased to 93.2%, as indicated by the post-test results. This training successfully improved the employees' pipe welding competencies, which are crucial for supporting the company’s operations.

Abstract

Permintaan terhadap bahan baku nikel terus meningkat seiring dengan pertumbuhan industri manufaktur, elektronik, dan baterai. Proses ekstraksi bijih nikel laterit melalui jalur hidrometalurgi, khususnya metode atmospheric leaching (AL), menghasilkan campuran padat-cair yang perlu dipisahkan melalui tahapan filtrasi. Filtrasi yang efisien dibutuhkan untuk memisahkan residu padatan dan filtrat dengan waktu proses yang singkat dan konsumsi energi minimal. Keterbatasan dari alat filtrasi konvensional seperti plate frame filter press mendorong perlunya inovasi dalam perancangan alat filtrasi yang lebih hemat energi dan mudah dioperasikan. Penelitian ini bertujuan untuk merancang dan membangun alat vertical pressure filter berbasis pompa hidrolik dengan kapasitas 600 mL yang digunakan untuk menyaring hasil ekstraksi bijih nikel laterit. Evaluasi performa alat dilakukan melalui pengujian efisiensi pemisahan padat-cair menggunakan pelarut asam sitrat. Metode yang digunakan mencakup tahap perancangan alat menggunakan perangkat lunak CAD, fabrikasi menggunakan material akrilik, besi holo, dan filter cloth 450 mesh, serta uji coba alat terhadap parameter efisiensi filtrat dan residu. Alat yang telah dibuat memiliki spesifikasi kapasitas 600 ml, pompa dengan motor hidrolik DC 12 V, pelat saringan nylon 450 mesh, gaya dorong 1000 N, dan waktu filtrasi 30 – 180 s. Dengan spesifikasi alat tersebut, hasil pengujian menunjukkan bahwa nilai efisiensi filtrat sebesar 3,76% dan efisiensi residu sebesar 76%. Ini mengindikasikan alat mampu menahan padatan dengan baik, namun filtrasi cairan belum optimal. Oleh karena itu, alat perlu disempurnakan, antara lain melalui peningkatan tekanan, pemilihan media filter yang lebih sesuai, dan optimasi waktu filtrasi untuk meningkatkan kinerja alat secara menyeluruh.

Abstract

Peningkatan daya saing industri dalam negeri tidak terlepas dari peran strategis sumber daya manusia yang kompeten, terutama dalam sektor industri berat seperti pengolahan logam. PT Indonesia Morowali Industrial Park (PT IMIP) sebagai salah satu kawasan industri terbesar di Indonesia menghadapi tantangan dalam memenuhi kebutuhan tenaga kerja terampil di bidang pengelasan pipa. Metode pengelasan Shielded Metal Arc Welding (SMAW) menjadi salah satu teknik pengelasan utama yang membutuhkan keterampilan khusus, terutama untuk pengelasan pipa dengan posisi yang kompleks. Program ini bertujuan untuk meningkatkan kompetensi teknis karyawan PT IMIP melalui pelatihan pengelasan pipa menggunakan metode SMAW berbasis kompetensi, pemberian materi teori dan praktik, evaluasi kompetensi peserta, serta pendampingan berkelanjutan. Metode pelatihan dirancang interaktif dan aplikatif, mencakup posisi pengelasan 1G hingga 6G, serta standar keselamatan kerja industri. Hasil yang diharapkan dari kegiatan ini adalah peningkatan signifikan pada keterampilan teknis peserta, terbentuknya budaya kerja profesional, dan terbukanya peluang sertifikasi profesi bagi karyawan. Program ini tidak hanya memberikan dampak langsung terhadap peningkatan kualitas tenaga kerja industri, tetapi juga menjadi bentuk kontribusi nyata perguruan tinggi dalam mendukung pembangunan sumber daya manusia yang unggul dan relevan dengan kebutuhan dunia kerja.
