PT XYZ adalah salah satu perusahaan farmasi yang mengawali usahannya dalam kesederhanaan, namun mengemban cita-cita yang besar yang ada di kota sukoharjo. Produk - produk keseluruhan yang di hasilkan oleh PT XYZ sebagian besar menggunakan energi dari mesin boiler. Boiler merupakan alat yang digunakan untuk menghasilkan uap atau steam untuk berbagai keperluan, uap yang di hasilkan mesin boiler di gunakan untuk energi dalam proses produksi di seluruh PT XYZ. Mesin boiler batu bara yang berada di PT XYZ di operasikan 2 orang dalam 8 jam dan mempunyai 3 shif dalam 1 hari. Mesin boiler batu bara yang beroperasi 24 jam tentunya terdapat limbah akibat pembakaran batu bara yang disebut abu batu bara. Pekerjaan operator boiler yang harus mengemas abu batu bara menggunakan sekop kemudian di masukan ke dalam karung, sedangkan operator boiler harus mengoperasikan mesin boiler yang tidak bisa di tinggalkan dengan waktu lama menjadi masalah utama. Hasil dari perancangan alat bantu material handling untuk proses penanganan limbah abu batu bara yaitu rancanganan kereta rel pengangkut tong untuk abu batu bara yang bertujuan untuk operator boiler bisa lebih fokus mengoperasikan mesin boiler. Waktu proses penanganan limbah abu batu bara menggunakan karung mendapatkan waktu 9,21 jam, kemudian waktu proses penanganan limbah abu batu bara menggunakan kereta rel pengangkut dengan waktu 3,68 jam. Dari waktu proses dengan menggunakan karung lebih lama dengan selisih waktu 5,53 jam atau 60,04 % dan lebih efesien menggunakan kereta rel pengangkut. Untuk estimasi biaya ongkos material handling menggunakan karung adalah Rp 221,608,000,-/tahun dan menggunakan kereta rel pengangkut tong adalah Rp 156,162,256,-/tahun. Jadi dari perhitungan per bulan maka didapat selisih sebesar Rp 65,445,744,-/tahun atau hemat 29,53 %.

PT XYZ adalah salah satu perusahaan pertambangan batu bara di Indonesia. Dalam melaksanakan operasional pekerjaan pertambangan, kendala yang dialami PT XYZ pada periode Januari 2022 hingga Februari 2023 adalah pada bagian support power plant, yaitu pada tower lampu. Pada tower lampu Atlas Copco B5+, terjadi frekuensi kerusakan tidak terjadwal yang cukup tinggi. Kerusakan tersebut mengakibatkan rendahnya kinerja tower lampu Atlas Copco B5+. Akibatnya aktivitas produksi pada malam hari terganggu dan menimbulkan kerugian bagi perusahaan. Untuk mengatasi permasalahan ini, digunakan metode Reliability Centered Maintenance (RCM). Dengan metode ini, dihasilkan analisis mengenai mode kegagalan lampu tower Atlas Copco B5+, besarnya nilai risk priority number (RPN), analisis waktu antar kegagalan (MTBF), serta dihasilkan rekomendasi tindakan perawatan pada 3 komponen paling kritis yang paling tinggi nilai RPN-nya. Dari pengumpulan data primer diketahui 7 komponen mengalami mode kegagalan. Kemudian dengan perhitungan skor severity, occurance, dan detection; diperoleh tiga komponen dengan nilai RPN tertinggi yaitu filter bahan bakar (RPN 300), kapasitor (RPN 240), dan baterai (RPN 150). Hasil perhitungan mean time between failure (MTBF) pada komponen filter bahan bakar adalah 256,82 jam; kapasitor 714;29 jam; dan baterai 1.277,5 jam. Tindakan preventive maintenance yang yang disarankan untuk perawatan tiga komponen ini adalah penggantian. Penggantian filter bahan bakar disarankan untuk dilakukan sesudah 250 jam operasi, dari sebelumnya 500 jam operasi, untuk mengurangi terjadinya kerusakan tidak terjadwal. Untuk kapasitor dan baterai, tindakan perawatan yang disarankan adalah dengan menambahkan item ini pada lembar pemeriksaan berkala 7 hari. Penggantian kapasitor disarankan setiap 750 jam operasi, sedangkan penggantian baterai disarankan setiap 1.250 jam operasi.
