Abstract

Sistem Manajemen Keselamatan dan Kesehatan Kerja (SMK3) merupakan bagian penting untuk perlindungan tenaga kerja agar pekerja tetap aman, sehat, dan selamat. Penerapan SMK3 di perusahaan akan menghindarkan dari risiko kerugian moral maupun material, kehilangan jam kerja, maupun keselamatan manusia, yang diakibatkan oleh kecelakaan. Kecelakaan yang dapat terjadi seperti keracunan, terjatuh, kulit terbakar, terpapar bahan kimia, bagian tubuh terjepit, dan lain sebagainya. Penelitian ini bertujuan untuk mengetahui implementasi Sistem Manajemen Keselamatan dan Kesehatan Kerja di PT. AIMTOPINDO NUANSA KIMIA. Metode penelitian yang digunakan adalah secara kualitatif dengan cara observasi. metode ini lebih cenderung pada hasil yang deskriptif. Teknik pengambilan data dilakukan dengan wawancara, pemaparan presentasi dari narasumber dan purposive sampling karyawan. PT. AIMTOPINDO NUANSA KIMIA telah melaksanakan identifikasi risiko kecelakaan kerja, meliputi Faktor fisik, Faktor kimia, Faktor biologi, Faktor fisiologi (ergonomi), Faktor psikologi dan melakukan tindakan upaya pengendalian risiko yaitu Training (intern dan ekster), Penyediaan Alat kerja yang sesuai, Pemasangan rambu-rambu, Penyediaan APAR, Pemeriksaan kesehatan (awal dan rutin), Pemeriksaan atau pengukuran lingkungan (intern dan ekstern), Penyediaan kotak P3K, Penyediaan APD, Simulasi dan Asuransi. Implementasi Sistem Manajemen Keselamatan dan Kesehatan Kerja di PT. AIMTOPINDO NUANSA KIMIA sudah baik dari segi identifikasi risiko kecelakaan kerja, pengendalian risiko dan bahaya kecelakaan kerja, serta dasar hukum.

Abstract

The proposed blue ammonia production considers technical, environmental, and economic aspects. The design of the blue ammonia using CCUS (Carbon Capture, Utilization, and Storage) technology in this study contributes to reducing carbon emissions and providing a more environmentally friendly ammonia supply in East Java, Indonesia, due to the availability of raw materials and geological storage locations for CO2 storage. Technically, the blue ammonia production was simulated with Aspen Hysys V.14.0. uses the Kellogg process, where the ammonia converter operates at a temperature of 437.60 °C and a pressure of 141.9 bar. From the environmental aspect, as much as 68.34 tons/h of ammonia produced produces CO2 71.36 tons/h, which is a total emission of 1.06 tons CO2/ tons NH3. In this study, CO2 delivery with a pipe length of 85 km  (ID:539.8mm; OD: 558.7mm) was simulated using default parameters in Aspen Hysys V.14.0. In economic calculations from APEA (Aspen Process Economic Analyzer), the manufacture of blue ammonia designed in this study is very large, with a TAC (Total Annual Cost) of $82.25x106/year and an LCOA (Levelized Cost of Ammonia) of $93.28x108/ tons NH3. This study demonstrates the integration of CCUS technology into ammonia production, resulting in a reduction of CO₂ emissions by 1.06 tons CO₂ per ton of ammonia produced. The proposed system provides a practical approach for improving the environmental sustainability of industrial chemical processes.
