In this article, a risk assessment of the Nanofluid stabilization process was made in order to optimize the process parameters using the HAZOP methodology. The results showed that the main parameters for the HAZOP risk assessment are as follows: the weight fraction of the surfactant, the temperature when the surfactant is used, the pressure and the speed of the fluid in the homogenizer, the PH solution, the time and the power of ultrasound, the temperature of the stabilization process, the volume fraction of nanoparticles, the size of the nanoparticles, the side surface to the volume of Nano particles, zeta potentials, Nanofluid concentrations. The results of the risk number calculations before control actions showed that after control actions, all risk numbers decreased 50% and more, so this decrease was significant. This decrease showed that all control actions were appropriate and effective.

Kapal merupakan moda transpotasi untuk memindahkan penumpang atau barang dari satu tempat ke tempat lain melalui laut. Kapal dengan umur lebih dari 25 tahun secara umum tidak dapat dioperasikan lagi karena adanya Peraturan Menteri Perhubungan pada tahun 2005. Ketika umur kapal bertambah, maka kapal tersebut menjadi tidak efisien untuk dioperasikan. Scrapping kapal pada saat ini dianggap sebagai solusi terbaik kapal yang tidak beroperasi. Kegiatan Scrapping kapal meliputi persiapan peralatan dan pekerja, bersandarnya kapal, pemotongan dan pengiriman material hasil scrapping. Tujuan utama dari penelitian ini adalah menyusun skenario risiko dan menilai risiko yang ada pada industri scrapping kapal di Bangkalan Madura dengan metode Hazard and Operability Study (HAZOP). Metode HAZOP merupakan suatu cara identifikasi suatu risiko yang terjadi pada setiap pekerjaan dengan menggabungkan 2 kata penting yaitu parameter dan guideword menghasilkan penyimpangan (deviasi) hingga memberikan usulan tindakan pencegahan pada risiko kecelakaan. Analisis data dilakukan mulai mempersiapkan perlengkapan dan kondisi pekerja hingga pengiriman hasil scrapping. Metode berfungsi untuk mengetahui tingkat/level kecelakan pekerja dan dampak terhadap lingkungan di usaha scrapping kapal. Risiko terekstrim diperoleh oleh pembersihan sisa bahan bakar/oli dengan menggunakan sabun dengan nilai 19,32. Tindakan pencegahan meliputi Memperhatikan faktor-faktor keselamatan pada waktu perencanaan, pembangunan sistem keamanan, sistem keselamatan bagi pekerja ataupun lingkungan, hingga pengawasan atau pengecekan setiap pekerjaan, menyelidiki kerusakan yang terjadi pada kecelakaan dan memelihara kalender kejadian.

“…Although the application of HIRA and HAZOP in industry has been discussed by many authors [ 18,19,20,9] only a few attempts have been made to integrate HIRA and HAZOP. Based on our best of knowledge, there is less specific attention paid on investigating the potential hazards using systematic hazard or risks assessment approach, particularly for SME industry.…”

“…HAZOP is a systematic safety study towards the assessment of safety and the operation of complex equipment or production process [19]. Interest of HAZOP is used to identify possible hazards that arise in facilities management in the company, eliminate a major source of accidents, such as toxic releases, explosions and fires [14].…”

This study aims to investigate the potential hazards and accidents that might occur at batik printing PT. Batik Merak Manis and recommends practical solutions to enhance safety and health at the workplace. This research adopts Hazard Identification Risk Assessment (HIRA) and Hazard and Operability Studies (HAZOP) to perform risk identification and assessment in the workplace. There are 17 findings of potential hazards in the production areas of batik printing which can be categorized into five types of hazards including: workers attitude, work posture, work procedure, workstation, and physical work environment. Of the risk assessment, the obtained value of 34% in the category of extreme hazard, 24% hazard in the high and medium category respectively, and 18% lower hazard category. Proposed improvements are made based HAZOP analysis worksheet. The proposed practical solutions include improvements in work attitude, work posture, and physical work environment.
