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.

Abstract

Higher education has an important role in the Tri Darma, namely participating in truly educating the lives of the nation and state in society. One step is to make humans no longer objects of development but subjects of development. As a development subject, abilities and skills in mastering science and technology are certainly required. The use of welding technology has developed and is widely used and exploited in the wider community, especially in meeting industrial needs. One of the welding methods is Shielded Metal Arc Welding (SMAW), namely welding using an electric arc. The aim of this activity is to increase the welding competency of Bungku Mining Vocational School students by adding special skills in the form of SMAW welding and providing encouragement and assistance so that Bungku Mining Vocational School students are able to provide welding equipment that supports learning in the laboratory. The benefit of this activity is to provide knowledge and train skills in SMAW welding so that it can be used to develop laboratory facilities.

Abstract

In the increasingly advanced and dynamic world of the manufacturing industry, the need for a skilled and qualified workforce is becoming increasingly important. One of the key skills required in the industry is the ability to operate a lathe effectively and efficiently. Lathes are used to shape and smooth workpieces by rotating the workpiece against a stationary tool. These machines enable precise and high-quality manufacturing processes, so employees need to master the correct and efficient operation of lathes. However, there is still a problem with employees who are not skilled enough to operate lathes in companies in the Morowali metal industry area. This condition can certainly hamper the productivity and efficiency of the company, and have an impact on the quality of the products produced. So, it is necessary to conduct training and mentoring to improve their knowledge and skills. Training is carried out using several methods, namely surveys through interviews to determine the appropriate type of training. Providing material to improve knowledge using the lecture method. Direct observation to train participants' skills in operating the lathe. Evaluation of training to measure the level of achievement. The evaluation results obtained an average pre-test score of 54.3 and a post-test of 84.6. There was an increase of 30.7 points after the participants participated in the training activities. Thus, the training activities showed success in improving employees' knowledge of lathe operation. In addition, each employee also showed skills in completing the job sheet that had been given. So, the training carried out provides various benefits for employees in developing careers and for companies in increasing their productivity.
