Persediaan merupakan unsur aktiva perusahaan yang dapat memunculkan biaya dalam pengadaan maupun pengelolaannya sehingga harus di kelola secara efekktif dan efisien. Kelebihan persediaan dapat menaikkan biaya simpan, sedangkan kekurangan persediaan dapat menimbulkan permasalahan dalam proses produksi. PT X merupakan produsen rokok kretek yang permintaannya bersifat fluktuatif. Hal ini membuat perusahaan harus selalu memastikan ketersediaan bahan baku khususnya tembakau untuk kelancaran proses produksinya. Kendala yang dialami PT X dalam persediaan tembakau adalah tingkat pemakaian yang lebih rendah dari tingkat pengadaan tembakau, sehingga perusahaan mengalami kelebihan persediaan tembakau di gudang. Metode Continuous Review dengan Sistem (r,Q) digunakan sebagai pendekatan dalam penyelesaian masalah ini karena metode ini diklaim dapat meminimasi total biaya persediaan, sesuai untuk kondisi dimana tingkat kebutuhan terhadap material yang tinggi dan nilai satuan material yang mahal, serta sesuai untuk persediaan dengan fluktuasi permintaan yang tinggi. Berdasarkan hasil perhitungan total biaya persediaan, metode usulan ini terbukti mampu menghasilkan biaya persediaan yang lebih rendah dan mendapatkan penghematan sebesar Rp. 129.246.893,- atau 28,98% dari total biaya riil persediaan di PT X.

PT XYZ is the largest shipbuilding company in Indonesia. The company's products are shipbuilding and ship design based on consumer demand. In the production process of the BRS W-303 ship, defects were still found during welding, such as incomplete penetration and slag inclusion. The purpose of this study was to determine the percentage of the most dominant defects and the factors causing defects and to provide suggestions for improving the quality of welding. The methods used are Statistical Quality Control (SQC) and Failure Mode Effect Analysis (FMEA). SQC tools are check sheets, stratification, scatter diagrams, attribute control charts, and cause and effect diagrams. Then continue the FMEA analysis based on the cause-and-effect diagram for proposed improvements. Based on the results of Statistical Quality Control (SQC) research, it is known that the most dominant ship welding defects are incomplete penetration (32.81%) and slag inclusion (23.26%). Based on the results of research on Failure Mode Effect Analysis (FMEA) it is known that the root cause of the highest problem with RPN 288 is the determination of the root gap is too small or narrow. Recommendations for improvement that can be proposed are to ensure that the welder must read and understand the WPS used to weld correctly.
