Perkembangan industri di Indonesia, khususnya pada industri manufaktur, mengalami kemajuan yang cukup pesat. Populasi tenaga kerja industri bertambah seiring perkembangan industri dan nilai tambah industri nasional yang meningkat dengan jumlah sebanyak 30,992 orang pada tahun 2018, meningkat 17,92% dibanding tahun 2017. Namun, masalah dan penanggulangan pada kasus kecelakaan kerja masih kurang diperhatikan, dibarengi dengan jumlah kecelakaan kerja yang masih tinggi, tidak terkecuali di PT. Astra Daihatsu Motor. Maka dari itu penelitian dilakukan di area Assembly 2 di area pabrik PT. Astra Daihatsu Motor di kawasan Sunter, Jakarta, dengan metode Hazard and Operability Study (HAZOP) dan Fault Tree Analysis (FTA) untuk mengetahui potensi bahaya secara teliti serta mengungkap unsur-unsur yang berpotensi berbahaya dalam sistem. Pada penelitian ini ditemukan sebanyak 17 sumber bahaya dengan 2 sumber termasuk dalam level risiko tinggi, 3 sumber level risiko sedang, dan 12 sumber level risiko rendah. Analisis deduktif dengan Fault Tree Analysis didapatkan hasil dengan munculnya 5 basic event dari Thinner dan 4 basic event dari Lampu Heater dengan rekomendasi perbaikan pada aspek desain, konstruksi, dan pelatihan handling yang baik pada material tersebut. Abstract[Proposed Improvement of Hazard Sources In The Area of Assembly 2 With The Hazard And Operability Study And Fault Tree Analysis (Case Study: PT. Astra Daihatsu Motor)]The development of industry in Indonesia, especially in the manufacturing industry, has experienced rapid progress. The industrial labor population increased as industry development and national industrial value added increased by as many as 30,992 people in 2018, an increase of 17.92% compared to 2017. However, the prevention and countermeasures in cases of workplace accidents are still not considered as priority, including in PT. Astra Daihatsu Motor. Therefore a research has been conducted in the Assembly 2 area at the PT. Astra Daihatsu Motor in the Sunter area, Jakarta, using the applicability of Hazard and Operability Study (HAZOP) method and the Fault Tree Analysis (FTA) method to carefully identify potential hazards and reveal potentially dangerous elements in the system. In this study 17 sources of hazards were found with 2 sources including high risk level, 3 medium risk level sources, and 12 low risk level sources. Deductive analysis with Fault Tree Analysis is obtained, namely 5 basic events from Thinner and 4 basic events from the Heater Lamps with recommendations on aspects of design, construction, and handling training in the material.Keywords: work accident; hazard and operability; risk level; fault tree analysis
