ABSTRAK/ABSTRACT

Proses pemesinan pada mesin cylindrical grinding konvensional di PT. Inti Presisi Toolsindo membutuhkan penggunaan cairan pendingin (coolant) dalam volume tinggi untuk menjaga kualitas permukaan benda kerja. Namun, interaksi antara putaran batu gerinda berkecepatan tinggi dengan cairan pendingin menghasilkan residu berupa kabut minyak (oil mist) yang menyebar ke udara. Paparan oil mist ini memicu dua risiko utama, yaitu menciptakan kondisi lantai area kerja yang licin serta risiko gangguan pernapasan bagi operator akibat terhirupnya Particulate Matter (PM) berbahaya. Penelitian Tugas Akhir ini bertujuan untuk merancang, membuat, dan menguji sistem Cover Oil Mist Collector yang efektif untuk mengendalikan sebaran polutan tersebut. Metode penyelesaian masalah meliputi observasi lapangan, studi literatur, reverse engineering, perancangan desain menggunakan software Autodesk Inventor, serta analisis potensi bahaya dengan metode HIRARC. Struktur cover dibuat secara custom berskala 1000 mm x 1031 mm x 717 mm menggunakan material plat baja karbon rendah SPHC (Steel Plate Hot Commercial) dengan ketebalan 2 mm. Hasil pengujian menunjukkan bahwa implementasi Cover Oil Mist Collector mampu menurunkan tingkat risiko bahaya operasional dari kategori Medium ke kategori Low/Very Low berdasarkan penilaian HIRARC. Pengukuran kualitas udara menggunakan Air Quality Detector Monitor mengkonfirmasi adanya penurunan konsentrasi partikel PM1.0, PM2.5, dan PM10 secara signifikan di lingkungan sekitar operator. Dari segi mekanika struktural, kekuatan material dinyatakan aman dengan Safety Factor sebesar 4,24. Secara keseluruhan, alat penangkap kabut minyak ini berhasil meningkatkan standar Keselamatan dan Kesehatan Kerja (K3) serta menciptakan lingkungan kerja yang lebih bersih, sehat, dan produktif.

The machining process on the conventional cylindrical grinding machine at PT. Inti Presisi Toolsindo requires the use of high-volume coolant to maintain the surface quality of the workpiece. However, the interaction between the high-speed rotation of the grinding wheel and the coolant generates a residue in the form of oil mist that disperses into the air. Exposure to this oil mist triggers two primary risks, namely creating slippery floor conditions in the work area (potential for physical workplace accidents) and the risk of respiratory disorders for operators due to inhaling hazardous Particulate Matter (PM). This Final Project research aims to design, manufacture, and test an effective Cover Oil Mist Collector system to control the dispersion of these pollutants. The problem-solving methods include field observations, literature studies, reverse engineering, design modeling using Autodesk Inventor software, and hazard potential analysis using the HIRARC method. The cover structure was custom-made with dimensions of 1000 mm x 1031 mm x 717 mm using SPHC (Steel Plate Hot Commercial) low-carbon steel plate material with a thickness of 2 mm. The test results indicate that the implementation of the Cover Oil Mist Collector successfully reduced the operational hazard risk level from the Medium category to the Low/Very Low category based on the HIRARC assessment. Air quality measurements using an Air Quality Detector Monitor confirmed a significant reduction in the concentration of PM1.0, PM2.5, and PM10 particles in the environment surrounding the operator. In terms of structural mechanics, the material strength was declared safe with a Safety Factor of 4.24. Overall, this oil mist collector system has successfully enhanced Occupational Safety and Health (OSH) standards and created a cleaner, healthier, and more productive working environment.
