PT. XYZ sebagai produsen beton masih menghadapi permasalahan kualitas produk berupa retak, segregasi, kuat tekan tidak sesuai, serta dimensi produk tidak presisi. Penelitian ini bertujuan menganalisis potensi kegagalan yang muncul pada proses produksi beton serta merancang langkah pengendalian menggunakan metode Failure Mode and Effect Analysis (FMEA) dan Fault Tree Analysis (FTA). Data terkait cacat produk dihimpun selama periode juli 2024 hingga januari 2025, kemudian dilakukan analisis untuk menghitung nilai Risk Priority Number (RPN). Dari hasil perhitungan, diketahui bahwa cacat dengan nilai RPN tertinggi adalah retak pada beton (RPN=288), diikuti segregasi (RPN=168), kuat tekan tidak sesuai (RPN=162), dan dimensi produk tidak presisi (RPN=48). Analisis lanjutan dengan FTA mengungkap bahwa akar penyebab berasal dari faktor manusia, lingkungan, dan mesin. Usulan perbaikan difokuskan pada peningkatan pelatihan operator, perawatan mesin secara berkala, standarisasi prosedur curing dan mixing, serta pengendalian kondisi lingkungan produksi. Temuan ini diharapkan dapat membantu perusahaan dalam meningkatkan kualitas produk beton dan mengurangi tingkat cacat produksi.
